Abstract
A retard roller includes a roller main body, a shaft, a torque limiter, a holding member, and a restriction member. The torque limiter switches the roller main body between rotation and stopping. The holding member is disposed on one side of the roller main body in an axial direction thereof and supports the shaft. The restriction member is disposed on the other side of the roller main body in the axial direction thereof, includes a locking portion locked to the shaft, and restricts movement of the roller main body in the axial direction thereof. The roller main body is swingably supported via a first support portion provided in the holding member and a second support portion provided in the restriction member, and is pressed against the feed roller.
Claims5
A sheet feed device, comprising:
- a feed roller that rotates when a driving force is transmitted thereto, thereby conveying a sheet;
- and
- a retard roller that is pressed against the feed roller to form a nip portion and that conveys the sheet while separating the sheet from another sheet,
- wherein
- the retard roller includes:
- a roller main body that rotates about a rotation axis;
- a shaft that is attached to the roller main body and extends along the rotation axis;
- a torque limiter that switches the roller main body between rotation and stopping;
- a holding member that is disposed on one side of the roller main body in an axial direction thereof and that supports the shaft;
- and
- a restriction member that is disposed on another side of the roller main body in the axial direction thereof, that includes a locking portion locked to the shaft, and that restricts movement of the roller main body in the axial direction thereof, and
- the roller main body is swingably supported via a first support portion provided in the holding member and a second support portion provided in the restriction member, and the roller main body is pressed against the feed roller.
