Sheet feeding device and image forming apparatus
First Claim
1. A sheet feeding device comprising:
- a pickup roller configured to feed a sheet;
a feed roller configured to rotate around a rotating shaft so as to convey the sheet fed by the pickup roller;
a feed holder configured to support the pickup roller and the feed roller;
a supporting frame having a storage recessed part in which the feed holder is supported so as to be attachable and detachable along a direction crossing an axial direction of the rotating shaft; and
a driving shaft rotatably supported to the supporting frame on one side of the storage recessed part in the axial direction, the driving shaft being configure to be coupled to the rotating shaft so as to transmit a driving force to the rotating shaft,wherein the storage recessed part includes;
a first side wall and a second side wall opposing to each other in the axial direction and extending along the attachment/detachment direction of the feed holder, the first side wall being on the one side in the axial direction and the second side wall being on the other side in the axial direction;
a guide part provided on each of the first side wall and the second side wall along the attachment/detachment direction and configured to slidably guide the feed holder; and
a positioning part provided on either one of the first side wall and the second side wall and configured to position the feed holder guided along the guide part at an aligning position in which the driving shaft and the rotating shaft are aligned on the axis direction,wherein the rotating shaft is coupled to the driving shaft by sliding the feed holder positioned at the aligning position by the positioning part in the axial direction,wherein the second side wall is provided with a pressing part,the pressing part is configured to push the feed holder in the one side in the axial direction while the feed holder is sliding into the aligning position and to couple the rotating shaft to the driving shaft.
