Abstract
A medium ejection device includes a lever that is movably disposed at the position of a pair of ejection rollers including a first roller and a second roller that nip and eject a medium and moves from one of the rollers to another of the rollers to push the medium, a lever position adjustment unit that moves the lever in a movement direction to adjust an advance position, and a motor that transmits power to the pair of ejection rollers. When turning forward, the motor rotates the pair of ejection rollers in the direction in which the medium is ejected. When turning backward, the motor transmits power to the lever position adjustment unit and moves the lever.
Claims17
A medium ejection device comprising:
- a pair of ejection rollers including a first roller and a second roller that nip and eject a medium to be transported;
- a lever that is movably disposed at a position overlapping the pair of ejection rollers in an axial direction parallel to rotation shafts of the pair of ejection rollers, the lever moving in a movement direction from one of the first roller and the second roller to another of the first roller and the second roller to push the medium nipped between the pair of ejection rollers;
- a lever position adjustment unit that moves the lever in the movement direction to adjust an advance position;
- and
- a motor that transmits power to the pair of ejection rollers, wherein
- the lever includes a first lever and a second lever, the first lever being located on one side of the pair of ejection rollers in the axial direction, the second lever being located on another side of the pair of ejection rollers in the axial direction away from the first lever,
- the first lever and the second lever are disposed to sandwich the pair of ejection rollers in the axial direction, and
- turning of the motor in a first rotation direction rotates the pair of ejection rollers in a direction in which the medium is ejected, and turning of the motor in a second rotation direction that differs from the first rotation direction transmits power to the lever position adjustment unit and moves the first lever and the second lever to the advance position.
