Original feed control unit

摘要

An original feed control unit for a copying machine has programming means for variably setting a stop position of an original fed by an original feed device prior to the start of the copy operation. By varying the stop position, the size of the margin formed on the copy paper can be varied. The position of a detector for detecting a jam of the original may be also varied in accordance with the desired size of the margin in order to properly detect a jam.
