Medium feeding device and image forming device

An image forming device comprising a medium feeding device and an image forming unit, wherein

• the medium feeding device further comprises:
• a sheet holding unit, which holds a medium and is pivotally attached to a device main unit so that the sheet holding unit is pivotal between open and closed positions;
• a sheet feeding roller that is located close to the sheet holding unit and that feeds the medium to the inside of the device main unit;
• and
• a driving shaft that is located on an axis that is different from a rotation shaft for the sheet feeding roller and that drives the rotation shaft, and
• the image forming unit forms an image on the medium fed by the medium feeding device.

A medium feeding device comprising:

• a sheet holding unit, which is pivotally attached to a side of an image forming device so that the sheet holding unit is pivotal between an open position, in which the holding unit is ready for use, and a closed position, in which the holding unit is stored when not being used;
• a sheet feeding roller, which is located at an inner end of the sheet holding unit, wherein the sheet feeding roller feeds a sheet from the sheet holding tray to the inside of the image forming device through an opening in the side of the image forming device, wherein the sheet feeding roller is supported by a rotation shaft, which is coaxial with the sheet feeding roller;
• and
• a driving shaft, which drives the rotation shaft, wherein axes of the driving shaft and the rotation shaft are parallel, and wherein the axis of the rotation shaft is located outward of the axis of the driving shaft.
