Abstract: A sheet processing apparatus includes a sheet stacking unit where sheets to be processed are stacked, a regulating member, a sheet waiting unit, a first moving unit, a second moving unit, and a control unit. The regulating member abuts on one edge of sheets conveyed to the sheet stacking unit. The sheet waiting unit keeps sheets waiting, stacks the waiting sheets displaced sequentially, and then conveys the sheets to the sheet stacking unit. The first moving unit sequentially moves the conveyed sheets, starting from a lowermost sheet, to be abutted against the regulating member. The second moving unit moves the conveyed sheets to the first moving unit. The control unit controls a moving speed of the second moving unit so that a next sheet does not reach the first moving unit until the sheet moved by the first moving unit is abutted against the regulating member.

This document feeder is constructed such that one reversible motor provides the drive power for all of drive parts of the document feeder, that is, a document feeding part, a document conveying part and a document recovering part, thus substantially reducing the manufacturing cost of the feeder. The document conveyor belt, on which a document to be copied is closely laid, moves in the forward and reversed direction, thereby causing the document to be exactly set on a reference copying position of a contact glass of the copying machine and, in this respect, improving the operational efficiency of the automatic document feeder. The present invention also provides a control circuit for automatically controlling such an automatic document feeder.

Abstract: In a document feeder, documents are contained on a document rest in a stacked state. These documents are sequentially transported to a specified exposure region on a table glass member of a copying machine by a feeder and transporter and are then exposed. The documents are then discharged again onto the document rest. The documents are thereby circulated for copying. When the documents are small in number, the documents are not discharged until a copying operation of a necessary number of sheets is completed, and the documents are moved back and forth for exposure between a transport path of the feeder and the transporter. This design enables the time required for copying a small number of documents to be shortened.

Abstract: In this printer, switching between a single-sheet form feed path and a continuous form feed path occurs by rotating a paper guide when feeding the forms. When the printed single-sheet form is to be discharged onto a table, the tail end of the form is detected by a first single-sheet form sensor. Form feed is stopped for a moment, and the paper guide is rotated toward the continuous form feed path. Reverse feed of the form is resumed and continued until the tail end of the form reaches approximate center of the paper guide. The paper guide is then rotated toward the single-sheet form feed path. The tail end of the form is bent toward the table, and the form is discharged onto the table. As a result, single-sheet forms fed from a manual insertion port or from an automatic paper sheet feeder can be conveyed after finishing printing to the position where the forms are inserted in a stabilized manner without causing the forms to jam on the discharge path.

In the two-sided copy mode, side fences provided on an intermediate tray are moved toward and away from each other in matching relation to the paper size. Even when the entry of a paper sheet in and the refeed of a paper sheet from the intermediate tray occur alternately, paper sheets entered the tray can be accurately controlled in position with no regard to the paper size.

Abstract: A switch is located near a pair of register rollers for feeding a document sheet toward a platen glass. A pair of document-feeding rollers are located near a platen glass. When the switch detects the rear edge of the document sheet being fed by the register rollers, it generates a signal. Upon receipt of this signal, the document-feeding rollers rotate, thus feeding the sheet for a prescribed distance and placing it at a predetermined position on the platen glass. The image on the sheet, thus positioned, is copied. An upper roller and a lower roller contacting each other are arranged at the exit side of the register rollers. The document sheets are braked as they pass, one after another, through the gap between the upper and lower rollers and are fed at the same speed, thus reducing their speeds to one and the same speed in spite of their different inertias.

Abstract: A system for efficiently feeding normal sized and oversized documents into different imaging positions overlying an imaging platen. All documents are initially fed onto the platen from an infeeding position desirable for normal documents substantially downstream from the upstream end of the platen. A normal document is only fed unidirectionally downstream into an imaging position. A sensed oversized document is initially fed downstream, but then, after its trail edge has cleared the infeeding position, it is reverse fed towards the upstream end of the platen into a imaging position partially overlying the normally unused upstream portion of the platen. A baffle normally directly overlies that area of the platen. During the initial reverse movement of an oversized document has baffle is pivoted upwardly at its downstream edge, at the infeeding position, to provide a document guide surface under the baffle.
