Abstract
An original feeding system having a rotary drum provided with sheet original hold-down claws for clamping the leading edge of the sheet original against the surface of the periphery of the rotary drum and with a control mechanism for keeping the claws in clamping engagement with the sheet and releasing the claws from clamping engaging therewith. A belt drive is provided for feeding the copy sheet by holding same between the rotary drum and the belt. The rotary drum is adapted to be stopped in its rotation before it completes one revolution, while the belt drive continues to be driven to feed the sheet original, which is subjected to the frictional force exerted by the belt and slides along the surface of the rotary drum. Therefore, it is possible to feed a sheet original having a length larger than the circumferential length of the rotary drum.
