ALIGNMENT MECHANISM FOR SHEET FINISHING APPARATUS, IMAGE FORMING APPARATUS, AND ALIGNMENT METHOD FOR THE SHEET FINISHING APPARATUS

摘要

According to one embodiment, a sheet finishing apparatus includes a supporting unit, a positioning unit, a socket mechanism, and a moving unit. The supporting unit supports a sheet fed from an image forming unit. The positioning unit has a contact surface which a side end of the sheet placed on the supporting unit is come into contact with. The socket mechanism projects from the contact surface of the positioning unit and is located above the supporting unit. The moving unit comes into contact with the upper surface of the sheet placed on the supporting unit and moves the sheet in the direction of the contact surface of the positioning unit.
