Image forming apparatus for processing sheets of image-bearing copy paper

摘要

A copying apparatus having a stapling function and a punching function. When the allowable sheet capacity for stapling is X and the allowable sheet capacity for punching is Y and the both the staple and punch modes are selected, the number of processable sheets in the staple/punch mode is determined by setting the value X or Y, whichever is smaller, as the sheet capacity of the device. While processing is on-going in the staple/punch mode, the staple/punch mode is cancelled when the number of copy sheets exceeds the capacity of the mode.
