Abstract
A rotation device according to an embodiment includes a first gear, a second gear, and an energizing part. The first gear includes a toothless part and is connected with a rotation driving source. The toothless part is obtained by cutting a part of continuous teeth of the first gear. The second gear is arranged to be able to be engaged with the first gear and is rotated, when engaged with the first gear, in a predetermined direction by a rotation of the rotation driving source in one direction. The energizing part energizes the second gear in a direction reverse to the predetermined direction when the second gear is in a free state in which an engagement of the second gear with the first gear is released by the toothless part.
Claims14
A rotation device comprising:
- a first gear that includes a toothless part and is connected with a rotation driving source, the toothless part being obtained by cutting a part of continuous teeth of the first gear;
- a second gear that is arranged to be able to be engaged with the first gear and is rotated, when engaged with the first gear, in a predetermined direction by a rotation of the rotation driving source in one direction;
- and
- an energizing part that energizes the second gear in a direction reverse to the predetermined direction when the second gear is in a free state in which an engagement of the second gear with the first gear is released by the toothless part.
A rotation device comprising:
- a first gear that is connected with a rotation driving source;
- a second gear that is arranged to be able to be engaged with the first gear and is rotated, when engaged with the first gear, in a predetermined direction by a rotation of the rotation driving source in one direction;
- and
- an energizing part that energizes the second gear in a direction reverse to the predetermined direction, wherein
- at least one of the first and second gears includes a toothless part obtained by cutting a part of continuous teeth of the at least one of the first and second gears, and
- the energizing part has an energizing force in which a force for rotating the second gear by energization in the direction reverse to the predetermined direction is weaker than a force for rotating the second gear in the predetermined direction caused by the rotation driving source.
