Abstract:
Automatic sheet feeding of an installed roll is performed more reliably. To this end, a leading end F of a sheet is detected on the basis of a change in an output value of a sensor while causing a roll R to rotate in a winding direction using the sensor capable of detecting a distance to the sheet separated from the roll R. After the detection, the roll R is caused to rotate in a feeding direction, and a feeding state of the sheet is determined on the basis of the change in the output value of the sensor.

Claim (Index 1):
A printing apparatus comprising:\n a holding unit configured to hold a roll sheet being a continuous sheet wound in a roll form; a printing unit configured to perform printing on a sheet supplied from the holding unit; a driving unit configured to rotate in a first direction to cause the roll sheet held in the holding unit to rotate in a forward direction and supply the sheet to the printing unit; a sensor configured to change its output value in accordance with a distance to the sheet of the roll sheet held in the holding unit; a detecting unit configured to detect a leading end of the sheet on the basis of the output value of the sensor while causing the roll sheet to rotate in a reverse direction by causing the driving unit to rotate in a second direction opposite to the first direction; and a determining unit configured to determine a feeding state of the fed sheet on the basis of the output value of the sensor while feeding the sheet after switching a rotation direction of the driving unit from the second direction to the first direction after the detection.
