Abstract
A cleaning device includes a contact member that contacts a rotation surface and a lever device which displaces the contact member. The lever device includes a roller which contacts the rotation surface and a lever which supports the roller to rotate in response to a forward rotation of the rotation surface. The lever is displaced by receiving a force of the rotation surface through the roller and separates the contact member from the rotation surface, in response to a backward rotation of the rotation surface.
Claims15
A movable cleaning device comprising:
- a contact member to clean a rotation surface;
- and
- a lever device comprising:
- a roller contacting the rotation surface;
- and
- a lever axially supported to be rotatable, the lever to:
- support the roller to rotate in response to a rotation of the rotation surface;
- displace the contact member to a first state in which the contact member contacts the rotation surface, in response to a rotation of the rotation surface in a first direction;
- and
- displace the contact member to a second state in which the contact member separates from the rotation surface, in response to a rotation of the rotation surface in a second direction.
A conveying device comprising:
- a conveying body comprising a rotation surface;
- a contact member which is to be movable between a contact state and a separation state, wherein the contact state indicates that the contact member contacts the rotation surface of the conveying body, and the separation state indicates that the contact member separates from the rotation surface;
- a roller contacting the rotation surface;
- and
- a lever comprising:
- a rotation shaft fixed in a shaft hole to displace the contact member;
- and
- a hole to support a shaft of the roller, the lever to:
- support the roller to rotate in response to a rotation of the rotation surface;
- displace the contact member to the contact state against a friction force between the rotation shaft and the shaft hole in response to a rotation of the rotation surface in a first direction;
- and
- displace the contact member to the separation state against the friction force between the rotation shaft and the shaft hole in response to a rotation of the rotation surface in a second direction.
An image forming apparatus comprising:
- a conveying body comprising a rotation surface;
- a contact member which is to be movable between a contact state and a separation state, wherein the contact state indicates that the contact member contacts the rotation surface of the conveying body, and the separation state indicates that the contact member separates from the rotation surface;
- a roller contacting the rotation surface;
- and
- a lever comprising:
- a rotation shaft fixed in a shaft hole;
- and
- a hole to support a shaft of the roller, the lever to:
- support the roller to rotate in response to a rotation of the rotation surface;
- displace the contact member to the contact state against a friction force between the rotation shaft and the shaft hole in response to a rotation of the rotation surface in a first direction;
- and
- displace the contact member to the separation state against the friction force between the rotation shaft and the shaft hole in response to a rotation of the rotation surface in a second direction.
