ABSTRACT:
A copying machine permits a desired number of copies to be set therein even in a warm-up period after a power switch is turned on, and starts the operation of a timer after a first display unit displays a copy ready condition. When a manual sheet feed switch is turned on, the entry of a desired copy number is inhibited. When the manual sheet feed switch is turned on after the entry of a desired copy number, a second display unit is loaded with a numerical value "1", the copy number is stored in a memory, and the timer is disenabled. As the manual sheet feed switch is turned off again, the preset copy number stored in the memory is indicated by the second display and the timer is activated.
