In inkjet printers there has been the problem that the recording medium becomes charged due to friction or peeling during conveyance of the recording medium, causing the ink mist to be drawn towards the charged locations and an unexpected pattern being recorded. Thus in the present invention, an ionizer that generates positive ions and an ionizer that generates negative ions are provided to a carriage, and by generating ions during the scanning of the carriage, static electricity arising at the recording medium is eliminated. By disposing ionizers generating ions of both positive and negative polarities at the carriage and performing on/off control of the generated ions for each scan, the amount of ions supplied per unit area of the recording medium is caused to be uniform, and so it is possible to efficiently eliminate static electricity.

In printers such that an inkjet head is mounted on a carriage that moves in a direction intersecting the direction of conveyance of a recording medium, and ink is discharged from the inkjet head, thus recording an image at the recording medium, there has been the problem that the recording medium becomes charged by friction or peeling during conveyance of the recording medium, resulting in ink mist being drawn to the charged locations and unexpected patterns being recorded. Thus, in the present invention, an ionizer that generates positive ions and an ionizer that generates negative ions are provided to the carriage, and ions are generated during the scanning of the carriage, thereby eliminating static electricity generated at the recording medium. The efficient elimination of static electricity is enabled by disposing ionizers generating ions having both positive and negative polarity at the carriage.

There has been a problem of having difficulty in removing an ink firmly adhered on a nozzle surface of an inkjet head in the cases of cleaning the nozzle surface using a wiper blade. The present invention uses, as the wiper blade, two kinds of wiper blades, i.e., a wiper blade configured from a porous member, and a wiper blade configured from an elastic member. Then, by having the wiper blades pass through a cleaning bath containing a cleaning liquid, the cleaning liquid is adhered on the wiper blades. Moving speed of the wiper blades is controlled, and in the cases of adhering the cleaning liquid on the nozzle surface, the wiper blades are moved at a high speed, and the cleaning liquid is adhered without sufficiently wiping the nozzle surface, and in the cases of wiping the nozzle surface, the wiper blades are moved at a low speed, and the nozzle surface is sufficiently wiped.
Provided is a recording device that is provided with a handle that prevents the possibility of fingers slipping, improving handling characteristics. For this purpose, the handle is provided on the back of the recording device. A plurality of slits are provided in a metal plate on the back side of the main unit and the handle is passed through these slits to secure both end sections of the handle. The central section of a belt protrudes to the outside and this portion acts as a handle for a user to grip. The slits are disposed in a vertical orientation and the width of the belt is disposed in a vertical orientation. Moreover, because the belt is restricted by the slits, the structure makes it easy for the user to grip the belt and to transmit force without twisting the belt. The recording device, having been laid down, can be easily set in an upright position again by gripping and lifting this handle.
The present invention prints using nozzle intervals to form a test pattern having a long cycle in a first outward and return scan. A correction value candidate is selected therefrom, a short-cycle test pattern is recorded using values before and after the correction value candidate, and the density of the test pattern is read by a sensor. An approximate expression of the value read from the short-cycle test pattern is used, and a correction to the value of a minimum resolution unit that is closest to the vertex of approximated lines is determined. By using such a correction value, and performing conveyance, the present invention is capable of recording an image in which dot deviation has been suppressed. Provided is a recording device which, in an inkjet printer, is capable of performing high quality recording by controlling in a more accurate and detailed manner the conveyance of a recording medium actually being used.

In the conventional technique, image quality defects occur when ink cannot be discharged in the same position for outward and return strokes when ink is discharged to a recording medium by outward and return strokes of a carriage in an inkjet printer. In the conventional technique, a test pattern using offset discharge timings is recorded on a recording medium, and an appropriate timing is input as a correction value. Conventional techniques that automatically read a test pattern are also known, but the precision thereof is poor because the test pattern is recorded without taking into account the state of a head. Therefore, in the present invention, a test pattern having a long period and a test pattern having a short period are recorded, and the density of the test patterns is read by a sensor. A candidate for an extreme value is calculated from the test pattern having a long period, and a rough adjustment is first performed. Then, in a range around the extreme value, an extreme value from the test pattern having a short period is calculated. An extreme value corresponding to a period belonging to both extreme values is used as a correction value. By fixing a discharge timing for the recording head using this correction value, an image can be recorded in which dot offset between outward and return strokes is suppressed.

There had been a problem wherein, when the leading end of of a wiper blade abuts an edge of a nozzle guard member (20) of an inkjet head, the amount of wear at that portion increases, resulting in a shorter life span for the wiper blade, as well as deterioration in cleaning performance, and difficulty in cleaning firmly adhered ink. To address this, a wiper blade is given a two blade configuration, comprising a porous wiper blade (4) and a wiper blade (3) having slits at two locations (15, 16), both ends (12, 14) of the wiper blade (3) being used for wiping the nozzle guard (20) and the middle portion (13) thereof being used for wiping the nozzle surface (22). By setting the distance between the slits (15, 16) so as to be shorter than the width between the side walls (21) of the nozzle guard and having this portion (13) wipe the nozzle surface (22), contact with the edge of the nozzle guard member (20) is prevented. Further, for each instance of wiping, the surface to be wiped is wiped by the porous wiper blade (4) while a cleaning solution (8) is applied thereon, thereby removing firmly adhered ink.
In the present invention, an inkjet head capable of changing dot sizes in printing is used, and image data (90) that the printing is based on have data widths corresponding to dot sizes. Further, print masks (91, 93) comprise data having widths of 2 bits or more. When print data (92, 94) are generated from the image data (90) and the corresponding print masks (91, 93), the print data (92, 94) are generated so as to have dot sizes that are based on combinations of image data (90) values and print mask (91, 93) values. As a result, it is possible to form dots having different sizes for the same value in the image data (90), depending on the mask value. The print head is divided into a plurality of blocks, and a different print mask (91, 93) is used for each block such that there is a complementary relationship among the blocks, thereby counteracting banding and other image quality flaws and preventing density loss when printing at low resolutions at high speed.

Therefore, if it is desired to confirm the status of a machine from a remote place, it may not be able to operate or confirm the status of the machine without escaping from the access restriction. In the present invention, the machine management computer contributes the information showing the status of the machine as the machine information from a computer in the local area network to a contribution service means on the Internet from the computer connected to the machine, stores that information in the contribution service means, and discloses that information to the user of the machine. The user can acquire the status of the machine via the contribution service.
The distal edge of a wiper blade is in constant contact with a specific location on an inkjet head, creating variability in the amount of wear occurring at the distal edge of the wiper blade, with the lifespan of the wiper blade being determined by the cleaning capabilities of those locations having the greatest amount of wear. Lifespan was limited by the decline in cleaning capabilities in only those portions of the wiperblade having the greatest amount of wear. Accordingly, by varying within a prescribed range the positions of the wiper blade and the print head during wiping, the distal edge of a wiper blade can be prevented from being in constant contact with a specific location on an inkjet head, preventing damage to a specific section due to a specific cause.
An objective of the present invention is, when displaying in a display screen a plurality of scaling images which are displayed on the basis of a prescribed source image, to create and display each scaling image more rapidly than before. To this end, desired regions (vertical-horizontal target regions (532, 533)) of a source image (690) are designated, and desired images (vertical-horizontal target images (700, 710)) including the entirety of the designated desired regions are read out from the source image and stored separately from the source image (690). A scaling rate (P) with respect to the source image (690) is acquired, and a scaled source image (620) wherein the source image (690) is scaled in both the longitudinal direction and the latitudinal direction by the scaling rate (P) is created and displayed in a display screen (53). Scaled desired images (scaled vertical-horizontal target images (621, 622)) wherein only the longitudinal direction of the separately stored desired images are scaled by the scaling rate (P) are created and displayed in the vertical-horizontal target regions (532, 533) overlapping the scaled source image (620).

Each of a plurality of releasing nails fixed on the frame is formed, by use of a respective flat plate made of resin, such that the releasing nail tapers down toward a front end thereof, while having a constant thickness in the thickness direction. The plurality of releasing nails are fixed on the frame in the longitudinal direction of the photoconductor drum such that any recording medium can be released regardless of the paper size thereof. The recording medium can be released from the photoconductor body regardless of the thickness of the recording medium. In addition, the frame can be shifted, thereby easily adjusting the positional relationship between each of the releasing nails and the photoconductor drum. In this way, there can be made an image forming apparatus that can release, by use of the releasing nails, any thin recording medium, even if used, from the photoconductor body without damaging the recording medium.
An ink jet recording device equipped with a sub-tank positioned between a main tank and an ink jet head is configured in such a manner that a tube pump is used for a pressure-adjusting means for adjusting the air pressure inside the sub-tank, and a valve for opening and closing a flow path is not used; and is further configured so that the inside of the sub-tank is partitioned by porous members into three spaces, namely, an ink inflow part, an ink outflow part, and an outside air communication part, and ink or gas invariably moves through the porous members. Thus, an increase in the size of a recording device equipped with a sub-tank capable of adjusting air pressure is minimized, and the removal of bubbles generated inside an ink jet head is achieved.
The purpose of the present invention is to easily modify drawing data at a working site, and to accurately reflect the modified content. A management server (2) stores drawing data (4), which constitutes a design drawing, and when there is a request from a terminal (3a-3c), generates, from the drawing data (4), terminal drawing data for display on the terminal and transmits the terminal blueprint data to the terminal (3a-3c). At the management server (2), an administrator can view handwriting specified by attribute information (5a1) superposed over the drawing data (4), and if the administrator approves, the management server (2) adds the attribute information (5a1) to an attribute file (6). When the attribute information (5a1) is added to the attribute file (6), the handwriting specified by attribute information (5a1) is displayed superposed over the drawing data (4) on the terminal (3a-3c). By adding the attributes of a terminal (3a-3c) to the attribute file (6), handwritten changes made using the terminal (3a-3c) can be added. The terminals (3a-3c) are usually offline, and can be connected to the management server (2) by a worker in order to download and display the drawing data (4) and the attribute file (6).
An ink jet recording device equipped with a sub-tank positioned between a main tank and an ink jet head is configured in such a manner that a tube pump is used for a pressure-adjusting means for adjusting the air pressure inside the sub-tank, and a valve for opening and closing a flow path is not used; and is further configured such that the inside of the sub-tank is partitioned by porous members into three spaces, namely, an ink inflow part, an ink outflow part, and an outside air communication part, and ink or gas invariably moves through the porous members. Thus, an increase in the size of a recording device equipped with a sub-tank between a main tank and an ink jet head is minimized, and bubbles generated inside the ink jet head can be removed.
Regarding an ink supply system provided with a sub-tank having a structure wherein a flexible film is attached around the peripheral edge of a rigid case, there are drawbacks that when the tank is initially filled with ink or when the ink is removed, if the flexible film is bent and closely attached to the inner wall of the rigid case, an ink flow path cannot be secured, and thus, defective filling may occur. Therefore, in the present invention, the sub-tank is structured to comprise a rigid case and a flexible film, the rigid case is provided with an ink inflow port and an ink outflow port, an ink flow path is formed between the rigid case and the flexible film, and a connection means is provided so that even if the flexible film is bent and closely attached to the inner wall of the rigid case from the inflow port to the outflow port, the ink inflow port and the ink outflow port can be connected to prevent the ink flow path from being blocked.
Provided are a flexible ink bag having a thickness which varies in accordance with the amount of ink, a detection plate secured to the ink bag, a securing plate for securing the ink bag to a hard case, a supply port which supplies ink from the ink bag and which is secured to the hard case, and a securing hole which is arranged on the side opposing to the side of the supply port and which is secured to the hard case. Further, an ink cartridge which houses the ink bag, and a recording device provided with the ink cartridge, are configured. Thereby, an ink bag which can be easily and precisely secured to a hard case, an ink cartridge, and a recording device mounted with the ink cartridge, are provided.
In a structure wherein an infrared-ray irradiation device is arranged directly above an inkjet head, the infrared-ray irradiation device will cause the temperature of a carriage to rise, resulting in poor discharge of ink. Further, employing a heat insulation material in the carriage will incur costs and require space for the heat insulation material. Even if a fan is attached to the device to introduce external air, decreasing the temperature around the carriage is difficult because the carriage is located at the center of the device. If external air is actively introduced and directed to the carriage, there are the problems of the temperature of a recording medium dropping and causing poor adherence of the ink landing on the recording medium, and the wind blowing on a nozzle surface of the inkjet head and causing poor discharge of ink. Therefore, a structure wherein the external air introduced into the device is directly drawn inside the carriage is provided, so that the temperature within the carriage can be made similar to the temperature of the external air regardless of the temperature in the device, to thereby enable a stable discharge from the inkjet head. At the same time, the external air introduced to the device is exhausted out of the device through a duct located at a position away from a print surface, so as to prevent the decrease of the temperature of the recording medium, and poor discharge of ink from the inkjet head.

Provided is an image forming device which detaches recording media from a photosensitive body using a detachment claw, without impairing the recording media, even if the media is thin in shape. For the detachment claw secured to the frame, a flat resin board is used. The detachment claw is formed so that thickness is gradually reduced toward the tip, and a slit which runs from the vertex toward the frame is provided. In the thickness direction, thickness does not gradually decrease, but rather stays constant. The frame is structured so that a plurality of detachment claws are secured in the length-wise direction of the photosensitive drum, and so that the recording media can be detached regardless of the paper size. The positional relationship between the detachment claw and the photosensitive drum is easily adjustable, by moving the frame.
The present invention provides a printing system which enables high-gloss print at a high concentration while reducing defective print such as color banding. The present invention makes it possible to use the effects of "spreading" to prevent defective print such as bi-directional banding which is caused by printing colors over another in two ways each in a different order, boundary banding, beading, and solid faint print. It is also possible to prevent the occurrence of a slight feeling of graininess and the degradation of the feeling of gloss, which can be said to be adverse effects of the "spreading." Furthermore, the white streaking or solid faint print or the like which may particularly occur in a combination with paper sheets having reduced dot diameters can be made unnoticeable by increasing the amount of discharge per unit area without decreasing the print speed. It can be thus expected to achieve a high print quality with stability.
