The sheet finisher includes a predetermined folding mode for receiving a sheet from a copy machine and which features a plurality of transfer guides through which the sheets received from the copy machine are selectively transferred; switching flappers for switching the flow of the sheet between guides, a temporary holding guide in which the leading end portion of sheets can be temporarily inserted; a sheet folding arrangement including press roller pairs for folding the sheets; a sheet discharge angle control device which varies the angle at which the sheets are discharged onto an upper tray in accordance with the folding mode that is being used; a tray shift mechanism for moving the tray left and right so as to stack the sheets which are discharged thereonto in a classifying manner; a friction roller for moving a predetermined corner of each of the sheets into a preselected corner of the tray; a fastening device for fastening the sheets which have been maneuvered into the preselected corner by the friction roller; a tray rise mechanism for changing the distance between the upper surface of the tray and the level at which the sheets are discharged; an escape mechanism which drops processed stacks of sheets from the upper tray into a lower one; and a tray angle varying mechanism for changing the angle of the lower tray when the stacks are dropped theretowards.

An extremely compact sorting apparatus includes a plurality of trays, each tray having a pin on each side of an entry portion side where a recorded sheet is received. The tray pins are guided by a vertical guide groove disposed on a frame so as to form a tray entry portion, as cam wheels with slots shift trays one level upwardly or downwardly. A transport plate for guiding a recorded sheet pivotally supports a discharge roller shaft and a cam wheel shaft coaxially. Furthermore, a motor for driving the discharge rollers and a motor for driving the cam wheels are mounted on the transport plate to provide a transport unit. When a recorded sheet is inserted onto the transport plate, it is detected by a detector, so that the drive of the discharge rollers begins and the recorded sheet is discharged to the tray entry portion. When this discharge is completed, the drive of the cam wheels begins so that the trays are shifted by one level. At this time, the cam wheels shift integrally with the transport plate so that the sorting machine is readied for insertion of the next recorded sheet.
