Abstract
In a sheet supply apparatus, a type of sheet to be used can be specified using a sensor that detects a sheet separated from a roll at the time of automatic sheet feeding. The sheet supplying apparatus includes a driving unit configured to cause a roll including a wound consecutive sheet to rotate in a first direction for feeding the sheet or a second direction opposite to the first direction, a sensor that detects the sheet separated from an outer circumferential surface of the roll, and a specifying unit. In a case in which the sensor detects a leading end portion of the sheet while the roll is being rotated in the second direction, the driving unit changes a rotation direction of the roll from the second direction to the first direction and feeds the sheet, and the specifying unit is configured to specify a type of the sheet on the basis of an output of the sensor while the roll is being rotated in the second direction.
