Abstract
A pressing rotator can contact a rotatable member. An arm rotatably supports the pressing rotator and changes the distance from a rotation center of the pressing rotator to the rotatable member by rotation. A pusher is rotatable around a rotation center of the arm. An elastic member is located between the arm and the pusher and biases the arm in a direction in which the pressing rotator contacts the rotatable member. A cam follower is mounted on the pusher. The cam can contact A cam follower and is rotatable around a first rotation center. The distance from the rotation center of the arm to the first rotation center of the cam is shorter than the distance from the rotation center of the arm to the center of the cam follower.
Claims20
A pressing device, comprising:
- a rotatable member;
- a pressing rotator configured to contact the rotatable member;
- an arm configured to rotatably support the pressing rotator and to change a distance between a rotation center of the pressing rotator and the rotatable member by rotation;
- a pusher rotatable around a rotation center of the arm;
- an elastic member located between the arm and the pusher and configured to bias the arm in a direction in which the pressing rotator contacts the rotatable member;
- a cam follower mounted on the pusher;
- and
- a cam configured to contact the cam follower and to rotate around a first rotation center, in which a distance between the rotation center of the arm and the first rotation center is shorter than a distance from the rotation center of the arm to the center of the cam follower.
An image processing apparatus, comprising:
- a scanner,
- an image forming unit,
- a sheet feeder,
- a conveyance unit, and
- a pressing device, comprising:
- a rotatable member;
- a pressing rotator configured to contact the rotatable member;
- an arm configured to rotatably support the pressing rotator and to change a distance between a rotation center of the pressing rotator and the rotatable member by rotation;
- a pusher rotatable around a rotation center of the arm;
- an elastic member located between the arm and the pusher and configured to bias the arm in a direction in which the pressing rotator contacts the rotatable member;
