Abstract
A driving device includes a conveyer roller, a solenoid, a lever including a boss, a first gear, a pendulum gear, and a frame including a supporting shaft. The lever is engageable with the solenoid and is movable between a first position and a second position. The pendulum gear is movable in conjunction with movement of the lever between a third position, at which the pendulum gear meshes with the first gear, and a fourth position, at which the pendulum gear is disengaged from the first gear. The supporting shaft is inserted in the boss of the lever. The supporting shaft includes a first contact portion and a second contact portion contacting the boss of the lever, and a separated portion spaced from an inner circumferential surface of the boss and located between the first contact portion and the second contact portion.
Claims9
A driving device comprising:
- a conveyer roller extending in an axial direction;
- a solenoid;
- a lever engageable with the solenoid, the lever being movable between a first position, at which the lever is pulled by a pulling effect of the solenoid, and a second position, at which the lever is released from the pulling effect of the solenoid, the lever including a boss protruding in the axial direction;
- a first gear configured to transmit a driving force to the conveyer roller;
- a pendulum gear movable in conjunction with movement of the lever between a third position, at which the pendulum gear meshes with the first gear, and a fourth position, at which the pendulum gear is disengaged from the first gear;
- and
- a frame including a supporting shaft, the supporting shaft extending along the axial direction and being inserted in the boss of the lever,
- wherein the supporting shaft includes:
- a first contact portion contacting the boss of the lever;
- a second contact portion contacting the boss of the lever, the second contact portion being separated from the first contact portion in the axial direction;
- and
- a separated portion spaced from an inner circumferential surface of the boss and located between the first contact portion and the second contact portion.
