Abstract

A paper anti-skew device for maintaining alignment and pre-venting skewing of sheets fed from a stack into a copy sheet mass in an electrostatic copying machine for producing copies of documents. Sheets S are fed from lead edge by a top feeding pneumatic device 45 in seriatim. The anti-skew device 50 rests on top of the stack of sheets along the trailing edge of the stack and is longitudinally co-extensive with the trailing edge thereof. Corner portions 52 and 54 extend from the longitudinal portion of the member at an angle of 90° for a predetermined distance to maintain alignment of the trailing corners of the topmost sheets as they are fed and which may stick and skew relative to the direction of the copy sheet path in the absence of the anti-skew device. Cutout portions 56 are to accommodate the tray.
