Abstract
A rotation device includes: a rotary body having a recess in an outer peripheral surface thereof; and a brush configured to come into contact with the outer peripheral surface of the rotary body to remove a foreign matter adhering to the outer peripheral surface, in which the brush is separated from the outer peripheral surface of the rotary body in a state where rotation of the rotary body is stopped.
Claims16
A rotation device comprising:
- a rotary body having a recess in an outer peripheral surface thereof;
- and
- a brush configured to come into contact with the outer peripheral surface of the rotary body to remove a foreign matter adhering to the outer peripheral surface, wherein
- the brush is separated from the outer peripheral surface of the rotary body in a state where rotation of the rotary body is stopped, and wherein
- the rotation of the rotary body is stopped at a position where the recess opposes the brush, so as to separate the brush from the outer peripheral surface of the rotary body in a state where the rotation of the rotary body is stopped.

A rotation device comprising:
- a rotary body having a recess in an outer peripheral surface thereof;
- a brush configured to come into contact with the outer peripheral surface of the rotary body to remove a foreign matter adhering to the outer peripheral surface;
- and
- a contact member, wherein
- the brush is separated from the outer peripheral surface of the rotary body in a state where rotation of the rotary body is stopped, wherein
- the brush rotates, wherein
- the contact member is configured to come into contact with the rotating brush to drop the foreign matter adhering to the brush, and wherein
- the rotation device further comprises a separation mechanism configured to move the brush outward in a radial direction of the rotary body in a state where the rotary body is stopped, so as to separate the brush from the outer peripheral surface of the rotary body without changing a positional relationship between the brush and the contact member.
