a conveyance unit that conveys a material to be conveyed, wherein the conveyance unit comprises a first conveyance roller;
a guide unit that guides the material to be conveyed, the guide unit being movable between a first position at which a first conveyance path is formed and a second position at which a second conveyance path is formed, wherein the guide unit comprises a guide surface;
a driving motor that drives the conveyance unit and the guide unit;
a first contact surface that comes into contact with the guide unit moving in a first moving direction from the second position to the first position at the first position by a driving force of the driving motor to restrict the movement of the guide unit in the first moving direction; and
a blocking unit that blocks transmission of the driving force of the driving motor to the guide unit when a moving load greater than or equal to a predetermined load acts on the guide unit moving in the first moving direction, wherein the blocking unit comprises a torque limiter,
wherein the driving motor sets a driving speed until the guide unit positioned at the second position is brought into contact with the first contact surface at the first position to be less than a driving speed after the guide unit is brought into contact with the first contact surface.
