An apparatus for sorting sheets on a tray in which a stacking position of sheets is changed for each set number of sheets to one of different stacking positions on the tray, includes a movable pressing member coming in contact with a discharging roller on its low position so that a discharging speed of the sheet is reduced, a movable lower guide plate so that the lower guide plate is positioned lower than a upper portion of the discharging roller on its low position; a sensor to detect a passage of a sheet; and a driving device to move the lower guide plate and the pressing member in response to a signal from the sensor.

Sheet sorting apparatus

A recording sheet finisher in use with an image forming apparatus such as a copier. The recording sheet finisher includes a stacker for stacking recording sheets, an aligning member for aligning the bundle of the recording sheets on the stacker, a counter for counting a number of the recording sheets bundled on the stacker, and a controller for controlling the aligning member so that the aligning member aligns the bundle of recording sheets after a first predetermined time period after the last one of the recording sheets is conveyed onto the other ones when the number of recording sheets bundled on the stacker is 25 or more, and aligns the bundle after a second predetermined time period when the number is not less than 25.

Recording sheet finishing apparatus

A recording sheet finishing apparatus connected with an image forming apparatus, in which recording sheets delivered from the image forming apparatus are stapled and the stapled sheets are ejected. The apparatus includes a plurality of stackers each having at least one stapler. The apparatus further includes a control means in which the recording sheets delivered from the image forming apparatus are stapled alternately by the staplers for each set of recording sheets and after that, each of the stapled set of recording sheets are delivered from the stapler to a delivery sheet tray, where a conveyor belt which transports the stack is operated at two different speeds with an initial speed followed by a faster speed to prevent damage to the stack.

A recorded sheet handling apparatus includes an intermediate holding section as a stacker for holding a set of recorded sheets externally fed one by one and stacked in a feeding order, a handling unit for selectively punching and/or stapling the set of recorded sheets held in the intermediate holding section at a holding position, a storage tray for storing the handled recorded sheets, first convey rollers for conveying the recorded sheets prior to handling to the intermediate holding section, and second convey rollers for conveying the handled recorded sheets to the storage tray.

Recorded sheet handling apparatus

A recorded sheet handling apparatus includes a holding unit for temporarily holding a set of recorded sheets externally fed one by one, a pair of side plates for moving the recorded sheets by a predetermined distance in a direction perpendicular to a recorded sheet convey direction prior to stapling when a size of the recorded sheets is a predetermined size, a punching machine and staplers for punching or stapling the set of recorded sheets while the sheets are held by the holding unit, and a conveying unit for conveying the punched or stapled copied sheets so as to exhaust the sheets.
