Publication number: 20210094786Abstract: 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.Type: ApplicationFiled: September 24, 2020Publication date: April 1, 2021Inventors: Nobuyuki MIZUSHIMA, Kazuyoshi OHASHI, Akinori MUROMACHI, Kohei UENO
