Feeding device

A feeding device to transport a recording medium, the feeding device comprising:

• a main body having a drive source;
• a tray that is attached to the main body and on which the recording medium is to be loaded;
• a side guide unit provided on the tray and configured to move in a width direction of the recording medium to align positions of edge portions of the recording medium loaded on the tray;
• an operation arm portion attached to the main body and configured to move in the width direction by rotational movement from a cam follower configured to receive a driving force from the drive source;
• and
• an operation lever configured to rotate around a rotation shaft and move the side guide unit in case the driving force is transmitted,
• wherein the operation arm portion transmits the driving force to the operation lever in case that the operation arm portion abuts on the operation lever, and
• wherein the operation arm portion is formed at one end of the cam follower that is rotatable around an axis orthogonal to the width direction and the other end of the cam follower is configured to abut on a cam driven by the drive source.

A printing apparatus comprising:

• a printing unit configured to perform printing on a recording medium;
• a main body having the printing unit, a base, and a drive source;
• a tray that is rotatably attached to the base and on which the recording medium is to be loaded;
• a side guide unit having side guides provided on the tray without extending onto the base and configured to move relative to each other in a width direction of the recording medium to align positions of edge portions of the recording medium loaded on the tray;
• an operation arm portion attached to the main body and configured to move in the width direction by rotational movement from a cam follower configured to receive a driving force from the drive source;
• and
• an operation lever configured to rotate around a rotation shaft and move the side guides in case the driving force is transmitted,
• wherein the operation arm portion transmits the driving force to the operation lever in case that the operation arm portion abuts on the operation lever, and
• wherein the tray is configured to rotate around a tray rotation axis of the tray, and the operation arm portion and the operation lever abut on each other at a position of the tray rotation axis.
