ABSTRACT:
A sheet supply device including: a device main body; a storage cassette having a stacking portion on which a sheet is loaded; a lifting mechanism that lifts up the stacking portion by using driving power supplied from a driving source; a delivery unit that is disposed above the stacking portion and performs a delivering operation in a contact state with the sheet on the stacking portion lifted up by the lifting mechanism, thereby delivering the sheet to a downstream side in a conveying direction; a control unit that controls the delivering operation of the delivery unit; and a detecting unit that detects whether the sheet is loaded on the stacking portion at a predetermine detecting position above the stacking portion; wherein, when the detecting unit detects that the sheet is in existence, the control unit starts the delivering operation of the delivery unit.
