Sheet transfer apparatus and image reading apparatus

摘要

A sheet transfer apparatus transfers a sheet to a predetermined position. The apparatus includes a discharge tray; a support device for rotationally supporting the discharge tray; an interconnecting device that activates according to a rotation of the discharge tray; and a sheet regulating device engaging the interconnecting means to be movable between a regulating position for regulating a movement of the sheet and a retracted position for allowing the sheets on the discharge tray to move. A control device prevents the sheet regulating device from moving to the regulating position from the retracted position even though the discharge tray is rotated when a load greater than a predetermined value is applied to the sheet regulating device.
