Abstract

A liquid discharging apparatus includes a discharge unit capable of discharging a liquid to a discharge region, a medium movement unit capable of moving in movement directions while supporting a medium onto which the liquid is discharged, a base unit that constitutes a movement path along which the medium movement unit moves, a detected unit, and a detector unit capable of detecting a position of the medium movement unit by detecting the detected unit. The detected unit and the detector unit are disposed so that the detected unit is detected by the detector unit when the medium movement unit is at a protrusion position at which a one direction-side end portion of the medium movement unit which is at a one direction side in the movement directions protrudes more toward the one direction side than does a one direction-side end portion of the base unit.

First claim

What is claimed is:

1. A liquid discharging apparatus comprising:
a discharge unit capable of discharging a liquid to a discharge region;
a medium movement unit capable of moving in movement directions while supporting a medium onto which the liquid is discharged;
a base unit that constitutes a movement path along which the medium movement unit moves;
a detected unit; and
a detector unit capable of detecting a position of the medium movement unit by detecting the detected unit,
wherein the detected unit and the detector unit are disposed so that the detected unit is detected by the detector unit when the medium movement unit is at a protrusion position at which a one direction-side end portion of the medium movement unit which is at a one direction side in the movement directions protrudes more to the one direction side than does a one direction-side end portion of the base unit.

2. The liquid discharging apparatus according to claim 1 ,
wherein the detected unit and the detector unit are disposed so that the detected unit is detected by the detector unit when the medium movement unit is in a range between the protrusion position and a predetermined position at which the one direction-side end portion of the medium movement unit is a predetermined distance apart from the one direction-side end portion of the base unit to an another direction side in the movement directions.

3. The liquid discharging apparatus according to claim 2 ,
wherein the detected unit and the detector unit are disposed so that when the medium movement unit is at a position that is more to the another direction side than the predetermined position, the detected unit is not detected by the detector unit.

4. The liquid discharging apparatus according to claim 2 , wherein:
the discharge unit is disposed so as to be more to the another direction side than the medium movement unit when the medium movement unit is positioned at the protrusion position; and
the predetermined position is a position at which an another direction-side end portion of the medium movement unit reaches the discharge region.

5. The liquid discharging apparatus according to claim 2 , further comprising
an interfering object detection unit that detects whether or not an interfering object that interferes with the discharge unit when the medium movement unit moves is present on or at the medium movement unit,
wherein the interfering object detection unit is disposed so as to be more to the another direction side than the medium movement unit when the medium movement unit is positioned at the protrusion position, and
wherein the predetermined position is a position at which an another direction-side end portion of the medium movement unit reaches a detection region in which the interfering object detection unit is able to detect the interfering object.

6. The liquid discharging apparatus according to claim 1 , further comprising
a control unit that, when having accepted a predetermined instruction, causes the detector unit to execute a detection operation for detecting the detected unit.

7. The liquid discharging apparatus according to claim 6 , wherein
if the predetermined instruction is an instruction to turn on a power supply of the liquid discharging apparatus, the control unit causes the detector unit to execute the detection operation, and
if the detector unit detects the detected unit, the control unit does not cause the medium movement unit to move.

8. The liquid discharging apparatus according to claim 6 , wherein
if the predetermined instruction is a print start instruction to start a printing operation that discharges the liquid onto the medium, the control unit causes the detector unit to execute the detection operation, and
if the detector unit detects the detected unit, the control unit causes the medium movement unit to move to a print start position at which the printing operation starts.

9. The liquid discharging apparatus according to claim 6 , wherein
if the predetermined instruction is an instruction to turn off a power supply of the liquid discharging apparatus, the control unit causes the detector unit to execute the detection operation, and
if the detector unit detects the detected unit, the control unit turns off the power supply.

10. The liquid discharging apparatus according to claim 6 , wherein
the control unit causes the detector unit to execute the detection operation, and
if the detector unit does not detect the detected unit, the control unit causes the medium movement unit to move to the protrusion position.
