ABSTRACT:
The present invention relates to a device for feeding sheets, one by one, to an automatic photographic processor or the like. The sheet feeding device generally includes a suction pad for taking out an uppermost sheet of stacked sheets stored in a sheet placement unit, a delivery mechanism for delivering the uppermost sheet to a sheet discharge port, a shutter mechanism used to open and close the sheet discharge port, a sheet insertion slot for directly introducing an extra sheet other than said stacked sheets to the sheet discharge port, a cover capable of opening and closing the sheet insertion slot, a magazine capable of accommodating a roll of sheet therein and capable of being disposed in the sheet insertion slot, a swingable plate having one end coupled to a drive source and the other end brought into engagement with the shutter mechanism so as to open and close the shutter mechanism, and a sensor for detecting angular positions of the swingable plate. Alternatively, the shutter mechanism may be opened and closed using a rack and pinion system.
