The present invention proposes a self-standing housing body solving a typical program and stably standing as a penholder. Specifically, the self-standing housing body according to the present invention is a self-standing housing body including a housing portion having a main housing space surrounded by a bottom surface and side surfaces standing from the bottom surface, and a lid portion having a sub-housing space surrounded by an upper surface and side surfaces standing from the upper surface. An upper side of one side surface of the housing portion and a lower side of one side surface of the lid portion form a joint portion, and about the joint portion as a rotation axis, the lid portion is rotatably joined to the housing portion. When the lid portion is rotated approximately 180° relative to the housing portion and the side surface of the lid portion substantially contacts the side surface of the housing portion, the upper surface of the lid portion and the bottom surface of the housing portion are substantially flush with each other. An upper end portion of the side surface of the housing portion does not reach the upper surface.

The present invention provides a sharpening completion detection mechanism that does not apply a heavy load to a core tip, and especially proposes a mechanism that moves a pencil in an ejection direction immediately when the sharpening completion detection mechanism detects completion of sharpening to mitigate damage to the core. Specifically, a pencil sharpener according to the present invention includes: a slide unit that translates in pencil insertion and pencil ejection directions; a pencil biasing means supported by the slide unit; a slide locking means that locks a translation position of the slide unit upon the slide unit translating in the insertion direction; and a slide unit unlocking means that releases the lock for the translation position of the slide unit upon the sharpening completion detection means detecting a fully sharpened state of the pencil, and includes slide unit ejecting means that biases the slide unit in the ejection direction with energy stored by movement of the slide unit to a lock position.

The present invention provides a freestanding pen case which resolves various conventional problems and which stands independently as a stable pen stand. More specifically, this freestanding pen case comprises an accommodating portion (1) having a main accommodating space surrounded by a bottom surface (1e) and a side surface provided upright from the bottom surface (1e), and a lid portion (2) having an auxiliary accommodating space surrounded by an upper surface (2e) and a side surface provided upright from the upper surface (2e), characterized in that: one upper edge of the side surface of the accommodating portion (1) and one lower edge of the side surface of the lid portion (2) form a coupling portion (3); the lid portion (2) is coupled rotatably to the accommodating portion (1), with the coupling portion (3) as an axis of rotation; when the lid portion (2) is rotated through approximately 180° relative to the accommodating portion (1) and the side surface of the lid portion (2) substantially abuts the side surface of the accommodating portion (1), the upper surface (2e) of the lid portion (2) and the bottom surface (1e) of the accommodating portion (1) are in substantially the same plane; and an upper end portion of the side surface of the accommodating portion (1) does not reach the upper surface (2e).

Abrégé

The present invention provides a completion-of-sharpening detecting mechanism that does not apply a large load to a pencil-core tip, and the present invention particularly proposes a mechanism that mitigates damage to the core of a pencil by immediately moving the pencil in the ejection direction when the completion-of-sharpening detecting mechanism detects completion of sharpening. Specifically, a pencil sharpener according to the present invention is provided with: a slide unit that advances straightly in the pencil insertion direction and in the pencil ejection direction; a pencil impelling means that is supported by the slide unit; a slide lock means that locks the slide unit at a straight advancement position when the slide unit advances straightly in the insertion direction; a slide unit unlocking means that unlocks the slide unit at the straight advancement position when a completion-of-sharpening detecting means detects the sharpening-completed state of a pencil; and the like, the pencil sharpener being characterized by comprising a slide unit ejecting means that impels, when the slide unit moves to the lock position, the slide unit in the ejection direction by energy accumulated as a result of the movement.
