Abstract

A printing apparatus includes an automatic opening mechanism for an opening/closing cover, a carriage that has a print head configured to perform printing on a medium and that moves in a direction intersecting a transport direction of the medium, and a discharge portion that is exposed in a state in which the opening/closing cover is opened and that discharges a printed material. The automatic opening mechanism includes a lever for releasing maintenance of a closed state of the opening/closing cover by movement of the carriage. The discharge portion discharges the printed material outside the apparatus. The automatic opening mechanism is arranged so as to overlap a discharge opening region of the discharge portion in a height direction.

First claim

What is claimed is:

1. A printing apparatus comprising:
an automatic opening mechanism for an opening/closing cover, which is disposed along a first direction;
a carriage that has a print head configured to perform printing on a medium and that moves in a direction intersecting a transport direction of the medium;
a disk scale provided on a shaft of a transport roller that transports a printed medium in a transport direction in a height direction, the automatic opening mechanism overlapping the disk scale; and
a discharge portion that is exposed in a state in which the opening/closing cover is opened and that discharges the printed medium, wherein
the automatic opening mechanism includes a lever for releasing maintenance of a closed state of the opening/closing cover by movement of the carriage,
the automatic opening mechanism overlaps a discharge opening region of the discharge portion in a height direction,
the lever is disposed along a second direction perpendicular to the first direction, and
when the carriage comes to contact with the lever and causes the lever to rotate, the maintenance of the closed state of the opening/closing cover is released due to the displacement of the lever.

2. The printing apparatus according to claim 1 , further comprising:
a discharge tray that is provided inside the opening/closing cover in a drawable manner and that receives a printed material discharged in a state in which the discharge tray is drawn out.

3. The printing apparatus according to claim 1 ,
further comprising a medium support member located opposite the print head in the height direction, the automatic opening mechanism overlapping the medium support member.

4. The printing apparatus according to claim 1 ,
further comprising a motor that is a driving source of the transport roller in the height direction, the automatic opening mechanism overlapping the motor.

5. The printing apparatus according to claim 4 , wherein
further comprising a power transmission mechanism that transmits power of the motor in the height direction, the automatic opening mechanism overlapping the power transmission mechanism.

6. The printing apparatus according to claim 1 , wherein
further comprising an ink supply tube that supplies ink to the print head in a depth direction, the automatic opening mechanism overlapping the ink supply tube.

7. The printing apparatus according to claim 1 , wherein
further comprising a partition hinge, for a scanner unit, that is formed at an upper portion of the printing apparatus in a depth direction, the automatic opening mechanism overlapping the partition hinge.

8. The printing apparatus according to claim 1 , wherein
further comprising an operation range of the carriage in a moving direction of the carriage, the automatic opening mechanism overlapping the operation range.
