Abstract

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.
