Abstract

A printing apparatus including a roll paper accommodating unit configured to accommodate roll paper, a single sheet paper accommodating unit configured to accommodate single sheet paper, a printing unit configured to perform printing on the roll paper fed from the roll paper accommodating unit, and to perform printing on the single sheet paper fed from the single sheet paper accommodating unit, and a main body frame that supports the single sheet paper accommodating unit and the roll paper accommodating unit, in which the roll paper accommodating unit and the single sheet paper accommodating unit are located in ranges, in a front-back direction of the printing apparatus, overlapping a range in which the printing unit is present, and are located downward of the printing unit with respect to a vertical direction, and the roll paper accommodating unit and the single sheet paper accommodating unit are movable frontward of the printing apparatus.

First claim

What is claimed is:

1. A printing apparatus, comprising:
a roll paper accommodating unit configured to accommodate roll paper;
a single sheet paper accommodating unit configured to accommodate single sheet paper;
a printing unit configured to perform printing on the roll paper fed from the roll paper accommodating unit, and to perform printing on the single sheet paper fed from the single sheet paper accommodating unit;
a main body frame that supports the single sheet paper accommodating unit and the roll paper accommodating unit;
a first transport path that transports the single sheet paper from the single sheet accommodating unit;
a second transport path that transports the roll paper from the roll paper accommodating path;
a third transport path which connects to the first and second transport paths and transports the single sheet paper and the roll paper to the printing unit, the first and second transport paths connecting to the third transport path at an inverting roller;
a fourth transport path that transports the single sheet paper and the roll paper from the printing unit to the inverting roller, the fourth transport path branching from the third transport path at a branch point that is downstream of the inverting roller and upstream of the printing unit, the fourth transport path extending from the branch point to a first joining point where the second transport path contacts the inverse roller, and the first transport path contacting the inverse roller at a second joining point where the first and second transport paths connect, wherein a portion of the fourth transport path overlaps a portion of the third transport path in a vertical direction; and
a fifth transport path that transports the single sheet paper and the roll paper from the printing unit to an ejection port, wherein
the roll paper accommodating unit and the single sheet paper accommodating unit are located in ranges overlapping, in a front-back direction of the printing apparatus, a range in which the printing unit is present, and are located downward of the printing unit in the vertical direction, and
the roll paper accommodating unit and the single sheet paper accommodating unit are movable frontward of the printing apparatus.

2. The printing apparatus according to claim 1 , wherein
the single sheet paper accommodating unit is located downward of the roll paper accommodating unit in the vertical direction.

3. The printing apparatus according to claim 1 , wherein
a cutting unit configured to cut the roll paper, and
a cutting waste accommodating unit configured to accommodate cutting waste generated by cutting by the cutting unit, wherein
the cutting waste accommodating unit is not located on a movement path of the single sheet paper accommodating unit so that the single sheet paper accommodating unit is movable frontward of the printing apparatus with respect to the main body frame.

4. The printing apparatus according to claim 1 , wherein
the roll paper accommodating unit is configured to be withdrawn frontward of the printing apparatus with respect to the main body frame, by removal, from the main body frame, of a cutting waste accommodating unit located on a movement path of the roll paper accommodating unit.

5. The printing apparatus according to claim 1 , wherein
the single sheet paper accommodating unit is movable further frontward than a frontward movement range of the roll paper accommodating unit with respect to the main body frame.
