Claims

[Claims for Utility Model Registration] A sheet conveyance device that conveys a sheet 17 onto a conveyance path and then discharges the sheet from the conveyance path, the first roller 32 being rotatably supported on the supply side of the conveyance path; The first roller 32 is supported so as to be switchable between an active position where the sheet 17 is pressed and a non-active position where the sheet 17 is pushed away from the first roller 32. a second roller 33 capable of supplying sheets 17; a third roller 36 rotatably supported on the discharge side of the transport path; an operating position for pressing the sheet 17 to the third roller 36; a fourth roller 42 which is provided so as to be switchable between a separate inactive position and a fourth roller 42 that can eject the sheet 17 in cooperation with the third roller 36 when placed in the active position; and the fourth roller 42 is rotatable. a switching member 37 that supports the fourth roller 42 and can move the fourth roller 42 between two switching positions;
and an actuating member 55 that can similarly switch the second roller 33 to the active position or the non-active position when the second roller 33 is in the active position or the non-active position.
