PURPOSE:To surely control the dynamic operations of a display device by applying program interrupt signals from the outside at a fixed time interval to a microcomputer thereby controlling the operations. CONSTITUTION:In a step 8-1, the FF of an interrupt terminal INT is set; thereafter, an interrupt signal is inputtable and every time when the interrupt signal inputs, the outputs from PF0 to PF4 are set successively. In a step 8-2, whether a copy key is turned ON or not is judged and if turned ON, the step advances to 8-3, where a main motor and an exposure system go ON. From this point on, original scanning is accomplished and an electrostatic latent image is formed on a drum. In a step 8-4, a paper feed solenoid goes ON, and at the predetermined timing, transfer paper is delivered to the drum direction. In a step 8-5, the paper feed solenoid goes OFF. Thereafter, transfer takes place and in a step 8-6, the main motor and exposure system go OFF, and the step returns to 8-1. |
