摘要:
A sheet finishing apparatus of the present invention takes in sheets of paper ejected from an image forming apparatus through a taking-in port and clamping and conveying the sheets of paper by a pair of pinch rollers for post processing, has a sheet guidance member which supports one of the pair of pinch rollers and can rotate between a first position where the one pinch roller and the other pinch roller make contact with each other and a second position where the one pinch roller is released from the other pinch roller, and furthermore includes a tray for loading the sheets of paper conveyed by the pair of pinch rollers and an assist arm which is attached rotatably to the sheet guidance member and when the one pinch roller and the other pinch roller are in contact with each other, is projected in the direction for pressing the sheets of paper in the tray and when the one pinch roller is released from the other pinch roller, is rotated in the opposite direction.

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 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 post-processing apparatus discharges and conveys a sheet from a process tray to a storage tray, and decelerates a bundle hook and a paper discharge roller when the bundle hook reaches a discharge start position of a bundle of sheets. At this time, a tangential speed of the paper discharge roller is faster than a movement speed of the bundle hook. Subsequently, the sheet post-processing apparatus stops the paper discharge roller in accordance with a rotation position of the bundle hook, and then decelerates the movement speed of the bundle hook. After the sheets are stacked on the storage tray, the bundle hook accelerates to return to a home position. Additionally, the sheet post-processing apparatus includes a spool 17 having a sheet pressing guide member 16 with a bent portion 16A. When the sheets are conveyed to a process tray 13, the spool 17 is rotated forward to longitudinally align the sheets and then is backwardly rotated to press the sheets using elastic force of the sheet pressing guide member 16, thereby preventing a gap from occurring between the sheets or preventing the sheets from being misaligned.
