PURPOSE:To enconomize a memory by using jointly a timer means for counting a prescribed time, and a timer menas for executing an abnormality flickering display, after an abnormality has been detected. CONSTITUTION:A check of a copy key 47e, a stop key 46d, etc. in case of cassette feed paper copying, and an operation of a display by a key input are executed. When the stop key 46d is depressed, the operation is shifted to the next step and the display is varied to ''1''. Thereafter, when the copy key becomes on, an initial set value stored in a display RAM2 is inputted to an RAM1, the RAM1 is displayed on a display device and the initial number of set sheets is reset. A subtraction of a timer clock of forward rotation, backward rotation, etc. and a time-UP are checked. Subsequently, a subtraction of a timer clock of a cassette feed paper solenoid SL301 and a time-UP are checked, and after the time-UP, the cassette feed paper solenoid becomes off. In this way, a memory can be economized by using jointly a count timer means and an abnormality flickering display timer means. |
