Abstract
A document feed device provided with a pin tractor assembly which includes a pin tractor member supporting a number of feed pins and rotated by a feed shaft, and a body member nonrotatably mounted on the tractor member. Elastically deformable projecting bar with a slit protrudes from the body member. A stationary frame member is formed with a slot extending in the axial direction of the feed shaft. An eyelet portion is formed at each end of the slot. The projecting bar elastically engages the slot, thereby preventing the body member from rotating. As the rotating bar slides within the slot, the pin tractor assembly can move along the feed shaft so that its position is adjusted according to the width of a perforated sheet of material. The assembly may be located in either of two positions, depending on the width of the sheet, as the projecting bar alternatively engages the eyelet portions of the slot. The position of the assembly is shifted by manually operating a knob formed on the body member.
