ABSTRACT:
A preset counter apparatus is provided for copying machines having a plurality of key inputs for increasing or decreasing the number of copies to be made. The timer is used to measure a predetermined increment of time for changing the numerical value upon the continuation of a key input. The rate of change of the number of copies to be reproduced can be progressively increased, at least across a predetermined number of increments of values, by the continued activation key member.
