An object recognition device includes an illuminator configured to illuminate an object, an imager configured to take a first-type image of the object when the object is illuminated by the illuminator under a first illumination condition, and take a second-type image of the object when the object is illuminated by the illuminator under a second illumination condition different than the first illumination condition, and circuitry configured to calculate a position of the object based on the first-type image and the second-type image.
Provided are a medium conveyance apparatus, control method, and control program to enable determining whether multi-feed of a medium has occurred by a greater precision. A medium conveyance apparatus includes a storage device to store in advance region information of a predetermined region in a medium, a feed roller to feed the medium, a slant detection module to detect an amount of slant of the fed medium, an overlap detection module to detect region information of a region in which overlap has occurred in the fed medium, a correction module to correct the detected region information based on the amount of slant, and a multi-feed determination module to determine that multi-feed of the medium has occurred if the corrected region information does not correspond to the stored region information and determine that multi-feed of the medium has not occurred if the corrected region information corresponds to the stored region information.
B65H 7/12 - Controlling article feeding, separating, pile-advancing, or associated apparatus, to take account of incorrect feeding, absence of articles, or presence of faulty articles by feelers or detectors responsive to presence of faulty articles or incorrect separation or feed responsive to double feed or separation
B65H 7/08 - Controlling article feeding, separating, pile-advancing, or associated apparatus, to take account of incorrect feeding, absence of articles, or presence of faulty articles by feelers or detectors responsive to presence of faulty articles or incorrect separation or feed responsive to incorrect front register
A media conveyance device is provided with: a device body (1) in which a conveyance path (8) is formed; a paper feed tray (2) (95) supported by the device body (1); a paper output tray (3) (91) supported by the device body (1); a conveyance unit (11) that conveys a paper feed medium loaded on the paper feed tray (2) (95) along the conveyance path (8) and loads the paper feed medium on the output tray (3) (91); a first mechanism (34) that swings the paper output tray (3) (91) so that the paper output tray (3) (91) is stored in the device body (1), and stops the swinging of the paper output tray (3) (91) midway in the swing from a deployed position in which the paper output tray (3) (91) is deployed to a storage position in which the paper output tray is stored; and a second mechanism (35) that shortens the paper output tray (3) (91) when the swinging of the paper output tray (3) (91) is stopped.
A medium conveying apparatus includes a first optical sensor located on an upper part of the housing and in a central part of the housing in a direction perpendicular to a medium conveying direction, a second optical sensor located on an upper part of the housing and on a side of the first optical sensor in the direction perpendicular to the medium conveying direction, and a processor to detect a folding of a medium based on the first signal or the second signal, and stop feeding of the medium by the feed roller in accordance with a detection result of the folding of the medium. The first light emitter emits first light toward a downstream side of the medium in the medium conveying direction, and the second light emitter emits second light toward an upstream side of the medium in the medium conveying direction.
