Claims13
A sheet feeding device, comprising:
- a placement member having a placement surface on which a recording medium is placed;
- a friction body mounted to a part of the placement surface of the placement member;
- a pickup roller disposed so as to be opposed to the friction body on a side of the placement surface of the placement member, for pulling out the recording medium from the placement member by rotating in abutment against the recording medium;
- a drive mechanism for rotationally driving the pickup roller;
- and
- a lifting member for lifting up the placement member so as to bring the recording medium into abutment against the pickup roller when the recording medium is placed on the placement member and bring the friction body into abutment against the pickup roller when the recording medium is not placed on the placement member,
- wherein the drive mechanism rotates the pickup roller under a state in which the pickup roller abuts against the friction body, to thereby clean the pickup roller.
