Abstract
A sheet feed mechanism for feeding individual sheets from a stack thereof comprises a first generally horizontal surface for supporting the edge of a stack of sheets and a second surface for supporting a face of the stack, the second support surface being provided by a plate member supported above the first surface and inclined at an obtuse angle with respect thereto. The plate member is supported so that the second surface is urged towards the nip defined between the first support surface and a sheet feed roller in such a manner that as the second surface approaches the nip the obtuse angle increases. In a preferred embodiment a cam surface is provided on the plate member to adjust the rate at which the obtuse angle varies as the second surface approaches the nip. The preferred embodiment also includes means for adjusting the height of the nip defined between the sheet feed roller and the first support surface to permit feeding of different gauges of sheets.
