  • Publication number: 20210094786
    Abstract: A medium transporting apparatus includes a mounting portion configured to mount a medium, and a pressing portion configured to switch between a first state for pressing the medium against the mounting portion and a second state for releasing the medium. The pressing portion takes the first state in waiting for the medium to the mounting portion, switches to the second state in response to the sent medium and returns to the first state after the medium is sent to the mounting portion. When the last medium is mounted on the mounting portion, a timing at which the pressing portion returns to the first state from the second state is delayed with respect to the timing of the return therebefore.

  • Patent number: 10954091
    Abstract: A suction mechanism for suctioning a loop transporting belt a medium processed by a processing unit, a rotation mechanism for rotating the transporting belt, a stacker for stacking the medium transported by the transporting belt, and a change mechanism for changing a movable area are included. The rotation mechanism, after suctioning the medium to the transporting belt to rotate in a first rotation direction to transport the medium in a first transport direction, rotates the transporting belt in a second rotation direction to transport the medium in a second transport direction to stack the medium on a stacker. The change mechanism narrows a movable area when the medium is transported in the second transport direction compared to an area when the medium is transported in the first transport direction.
