ABSTRACT:
A sheet dispenser for dispensing sheets one at a time from a stack of notched photographic X-ray film sheets. The essential part of this device is a pendulum which is capable of swinging from side to side across the sheets, which are stacked at a slight angle to the vertical, and also back and forth in the plane of the thickness of the sheet stack. The pendulum is made from a roller which has a plough release member attached to it. When the pendulum is moved side ways until it is in line with the notch on the uppermost sheet the release member locates into the notch, and, as the sideways movement continues, ploughs under the sheet and detaches it, allowing it to fall under the action of gravity. The pendulum then moves sideways in the opposite direction, remaining in contact with the next sheet, until the release member locates into the notch on the next sheet whereupon the plough detaching operation is repeated.
