A medium feeding device comprising:
- a medium placing portion on which a medium to be fed is placed:
- a guide portion that is provided on the medium placing portion, guides a side edge of the medium in a width direction intersecting with a feeding direction of the medium, and is movable in the width direction;
- and
- a positioning mechanism that determines a position of the guide portion in the width direction,
- wherein the positioning mechanism regulates the position of the guide portion by positioning portions arranged with a predetermined interval in a first region of a moving region of the guide portion and regulates the position of the guide portion in a stepless manner in a second region which is a region other than the first region, and
- wherein the positioning mechanism includes
- a protruding portion that is provided on a side of the guide portion,
- a plurality of recessed portions, as the positioning portions, that is provided with the predetermined interval on a part corresponding to the first region in the medium placing portion and regulates the position of the guide portion by receiving the protruding portion, and
- a friction member that is provided on a part corresponding to the second region in the medium placing portion and regulates the position of the guide portion by frictional resistance between the protruding portion and the friction member.
A medium feeding device comprising:
- a medium placing portion on which a medium to be fed is placed;
- a guide portion that is provided on the medium placing portion, guides a side edge of the medium in a width direction intersecting with a feeding direction of the medium, and is movable in the width direction;
- and
- a positioning mechanism that determines a position of the guide portion in the width direction,
- wherein the positioning mechanism regulates the position of the guide portion by first positioning portions arranged with a first interval in a first region of a moving region of the guide portion and regulates the position of the guide portion by a second positioning portion disposed with a second interval narrower than the first interval in a second region which is a region other than the first region.
A medium feeding device comprising:
- a medium placing portion on which a medium to be fed is placed;
- a guide portion that is provided on the medium placing portion, guides a side edge of the medium in a width direction intersecting with a feeding direction of the medium, and is movable in the width direction;
- and
- a positioning mechanism that determines a position of the guide portion in the width direction,
- wherein the positioning mechanism regulates the position of the guide portion by positioning portions arranged with a predetermined interval in a first region of a moving region of the guide portion and regulates the position of the guide portion in a stepless manner in a second region which is a region other than the first region,
- wherein the moving region of the guide portion includes an outside first region which is a first region provided to the outside of the medium in the width direction, an inside first region which is a first region provided in the inside of the medium in the width direction, and a second region which is provided between the outside first region and the inside first region, and
- wherein the second region is a region where the position of the side edge of a medium having at least a postcard size in the width direction is regulated.
