Abstract
In an embodiment of the invention, a detection unit arranged near a feed roller is rotatably arranged. A space where the feed roller is attached and detached is formed by rotating the detection unit. The detection unit is rotated in accordance with an operation of attaching and detaching the feed roller to and from a shaft, and the maintenance of the feed roller is performed while the formed space is used.
Claims20
A sheet feeding device comprising:
- a feed member to transport a sheet in a containing section in a feeding direction;
- and
- a detection unit which is arranged to be close to the feed member, has a detection element to detect passing of the sheet, and rotates and moves to form a space for attachment and detachment of the feed member at a position adjacent to the feed member.
An image forming apparatus comprising:
- an image carrier;
- an image forming unit to form a toner image on the image carrier;
- a transfer unit to transfer the toner image to a sheet;
- a fixing unit to fix the toner image transferred to the sheet;
- a feed member to transport the sheet in a containing section in a direction toward the transfer unit;
- and
- a detection unit which has a detection element to detect that the sheet passes through a position of the feed member, and rotates and moves to form a space for attachment and detachment of the feed member at a position adjacent to the feed member.
An attachment and detachment method of a feed member to which a detection unit of an image forming apparatus is provided to be close, comprising:
- forming a space between the feed member and the detection unit by rotating the detection unit in accordance with a worker's operation of moving the feed member;
- attaching and detaching the feed member in the space;
- and
- rotating and returning the detection unit to a detection position after an operation of detaching the feed member by the worker is ended or an operation of attaching the feed member by the worker is ended.
