Provided is a drum surface scanner with which punched holes and/or cuts can be formed in a plate which has been correctly defined by position, and the plate can be clamped to a recording drum. When a plate ( P ) comes in front of movable pins (113), i.e., on a hole punch unit (4) side, the upper roller of a conveyor roller (125) moves down, and conveyor rollers (124,125), and conveyor belts (111) all start rotating in the positive direction. Once the plate ( P ) moves out of the range covered by a sensor (PH159), the movable pins (113) follow the tail end of the plate ( P ) at a given distance therefrom. When the front end of the plate ( P ) reaches the hole punch unit (4), the movable pins (113) which have been chasing the plate ( P ) push the tail end thereof to make the front end thereof abut to the hole punch unit (4). At the same time, based on the movement amount of the movable pins (113) from their original positions to current positions pushing the tail end of the plate ( P ), the plate ( P ) is checked for its length ( Y ). Plate conveyance with respect to positioning pins (51) on the recording drum (5) is carried out in a similar manner.

A device for acquiring an image of a slice medium, comprising: an upper channel plate (101) which is used for reserving a lower gap with a lower channel plate (102) to form a channel; the lower channel plate which is used for reserving the lower gap with the upper channel plate to form the channel; a driving wheel (103) which is used for driving a slice medium entering the channel to advance in the direction of the channel; a floating pressure roller (104) which is used for exerting a pressure on the slice medium, so that the slice medium is closely attached to the driving wheel; and an image collection device (105) which is used for collecting an image of the slice medium when the slice medium passes through the channel. The device for acquiring an image enables the slice medium to be always on the same plane in the process of channel transmission, without great fluctuation, thereby avoiding the change of a greyscale value of a collected image caused by fluctuation, thus ensuring that the greyscale value of the collected image may not influence analysis processing.

L'invention concerne un appareil de traitement de feuilles, comportant un bac d'approvisionnement équipé d'un capteur détectant la présence de feuilles dans ce bac. L'appareil comporte un organe (4) portant une matrice photosensible et une source lumineuse (5), chaque feuille (12, 13, 14) étant déplacée devant cet organe (4) pour en acquérir une image. Il comporte également un capteur incluant un doigt (15) mobile entre une position déployée et une position rétractée, pour identifier un état mécanique de l'appareil ou d'un de ses composants. Le capteur comprend un obturateur (17) lié en mouvement au doigt (15) en étant mobile entre une position fermée dans laquelle il réfléchit vers la matrice photosensible (6) de la lumière issue d'une portion de la source lumineuse (5), et une position ouverte dans laquelle il laisse passer la lumière issue de cette portion de la source lumineuse (5). L'invention s'applique notamment aux scanners et aux copieurs.

Disclosed is an image forming system comprising: a data processing apparatus (20); and an image forming apparatus (10), which are connected to each other through a communication line (N), and according to a print instruction transmitted from the data processing apparatus, the image forming apparatus performs an image forming on a sheet specified by the print instruction, wherein the image forming apparatus comprises: a setting section (141); a communication section (15); and a transmission control section (11), and the data processing apparatus comprises: a communication section (24); a registration section (23); and a printer driver section (21).
摘要:
When the last line recording is effected by a recording head at a tail end portion of a sheet, the recording head is controlled not to be passed through a lateral edge of the sheet opposite to or remote from a floating preventing portion, whereby a recording apparatus and a method for controlling such a recording apparatus in which a recording range at the tail end portion of the sheet can be increased without interfering with a scanning operation of the recording means regardless of kinds of sheets.
摘要:
An image forming apparatus comprises a plurality of decks for accommodating sheets, a feeder for feeding sheets from said decks, an image forming unit for forming an image on a sheet fed by said feeder, a detector for detecting thicknesses or colors of the sheets accommodated in said decks, an input unit for designating a desired thickness or color of the sheet, and a control unit for controlling said feed means to feed the sheet of the desired thickness or color from said decks.
摘要:
A portable image scanner capable of selecting a manual document loading mode in which a cover member (20) is united to a scanner body (1) to feed a cut-sheet document through a document passage (P) defined between the united scanner body and cover member for scanning the document (D), or a self-propelling mode in which the cover member (20) is separated from the scanner body to move the independent scanner body (1) on a thick document such as a book. The scanner body has a document sensor (16) for detecting the cut-sheet document placed in the document passage (P) in the manual document loading mode, and the thick document in the self-propelling mode to prevent the scanner body (1) moving on the document from falling out of the edge of the thick document.
