In order for skew relative to the transport direction to be detected in a sheet which is transported to a recording unit, a carriage is initially moved in a scanning direction to a first position and the sheet is transported in this state. Then, when the front edge of the sheet in the transport direction is detected by a second sensor, the carriage is moved in a direction so that the second sensor is no longer able to locate the front edge to a second position, which is separated from the first position by a regulating movement distance. Furthermore, the sheet is transported to where the second sensor locates the front edge of the sheet in the transport direction at the second position and skew in the sheet is detected based on this transport distance and the regulating movement distance. |

1. A printing apparatus comprising:
a transport unit configured to transport a medium to a recording unit configured to perform recording with regard to the medium, the medium having a lens sheet where a plurality of lenses are arranged parallel to each other; a carriage provided in the recording unit, the carriage being configured to move in a scanning direction which intersects with regard to a transport direction of the medium by the transport unit; a sensor provided in the carriage, the sensor being configured to locate presence or absence of the medium; a control unit configured to control operating of the transport unit and the carriage; and a detection unit configured to detect skew of the medium relative regard to the transport direction, the control unit being further configured to
move the carriage to a first position where a front edge of the medium in the transport direction is located by the sensor,move the carriage in a direction such that the sensor no longer locates the medium to a second position, which is separated from the first position by a regulating movement distance, when the front edge of the medium, which is transported to the recording unit by the transport unit, in the transport direction is detected by the sensor at the first position, andtransport the medium using the transport unit to where the sensor locates the front edge of the medium in the transport direction at the second position, the detection unit being further configured to detect skew of the medium relative to the transport direction of the medium based on the regulating movement distance and the transport distance of the medium by the transport unit from where the sensor locates the front edge of the medium in the transport direction at the first position to where the sensor locates the front edge of the medium in the transport direction at the second position. |
