摘要:
A sheet processing apparatus having a sheet post-processing unit for performing a post process such as aligning or binding sheets. The sheet processing apparatus is composed of a tray for supporting a sheet bundle, an auxiliary conveying unit including a first arm for hooking an end of the sheet bundle on the tray for moving the first arm, thereby conveying the sheet bundle to a predetermined position on the tray, and returning the first arm from the predetermined position to a home position, and a main conveying unit having a second arm for taking over the sheet bundle from the first arm at the predetermined position on the tray and hooking an end of the sheet bundle for moving the second arm, conveying the sheet bundle taken over, and discharging it from the tray.

A sheet processing apparatus comprises a processing tray for loading a sheet bundle, a first conveying unit having a rotary shaft which is installed at least at the end on the downstream side in the direction for moving the sheet bundle on the processing tray and is driven to rotate via a first drive source and a drive unit and a roller installed on the rotary shaft for loading and conveying the sheet bundle and discharging the sheet bundle from the end on the downstream side and from the processing tray, and a second conveying unit having a pair of pulleys having at least one of them installed rotatably on the rotary shaft on the downstream side driven to rotate via a second drive source and a drive unit, a belt stretched over the pair of pulleys, and an arm installed on the belt for hooking an end of the sheet bundle on the processing tray, conveying it together with the roller, and discharging the sheet bundle from the end on the downstream side and from the processing tray. The arm of the second conveying unit synchronizes the speed when moving along the straight portion of the belt with the rotational speed of the roller of the first conveying unit and changes the speed when moving in the peripheral direction of the pulley on the downstream side among the pair of pulleys from the rotational speed of the roller.

A sheet post-processing apparatus includes a processing tray and a stapler. The processing tray has a mounting area, a flexible portion, and an edge holding part. A sheaf of sheets is made on the processing tray. A sheet P to be stapled is stacked on the mounting area. The flexible portion is formed integrally with the mounting area and at the same level as the upper surface of the mounting area, along the edge of the mounting area of the side to staple the sheaf of sheets, and is bent easier than the mounting area in the direction of the thickness of the sheaf of sheets toward the mounting area. The stapler has a fixed part and an arm, and staples a sheaf of sheets. The fixed part is provided deviated from the upper surface of the mounting area to the mounting unit.

A sheet post-processing apparatus includes driving rollers that are arranged in a leading end position in a sheet conveying direction of a standby tray and axis of which are perpendicular to the conveying direction and driven rollers that rotate following the driving rollers and are provided in a front portion in the sheet conveying direction of the standby tray such that an interval thereof narrows in the sheet conveying direction. The driven rollers may be arranged in the front in the sheet conveying direction of the standby tray while being spaced apart from the standby tray.

An apparatus for processing printed sheets includes a processing tray and a standby tray having a pair of tray members that are movable in a width direction of sheets. The tray members are movable between a first position where a sheet is placed on the tray members and a second position where the sheet is dropped from the tray members. A roller mechanism for feeding the sheet onto the standby tray, a paddle mechanism, and an assist arm are arranged near a rear end of the standby tray. As the tray member moves from the first position to the second position, the paddle mechanism strikes a rear end of the sheet downward. The assist arm is placed near the roller mechanism to inhibit the rear end of the sheet from floating from the standby tray while the tray member is moving from the first position to the second position.

A post-processing apparatus has a standby tray to receive a paper sheet to be supplied from a digital copier, a processing tray to receive a paper sheet dropped from a standby tray, and a stapler to staple the rear end aligned on the processing tray. When a first paper sheet is supplied to the standby tray, the standby tray roller is brought into contact with the paper sheet and rotated reversely, the paper sheet is returned a little, and the rear end of the paper sheet is placed at the holding position on the tab. Then, the press member presses the rear end of the paper sheet, to receive a second paper sheet.
