<p>PURPOSE:To make the degree of freedom in the arrangement of internal units wider, by providing a delaying circuit which can optionally set time and outputting a recording leading edge signal to an external apparatus after delaying the signal in accordance with the set value of the circuit and, on the other hand, making copying operations to proceed in the order of paper feeding, resist, and transferring and fixing irrespectively of the external apparatus. CONSTITUTION:When an external apparatus makes a printing request, paper feeding is started and, when transfer paper passes the location of a pass sensor 3, a plunger 21 is turned off and the paper is resisted at the location of a resistor roller 4 a fixed time after. Then a plunger 41 is turned on by a plunger controlling signal for resistor roller and the transfer paper is sent to a transfer side. When a delayed time has passed in accordance with the set value of a delaying time setter after the signal of the pass sensor is turned on, a recording leading edge signal is outputted to the external apparatus. Since the paper feeding, resist, and transfer are made to proceed irrespectively of the external apparatus and the recording leading edge signal is outputted in accordance with the set value of the delaying time setter in such ways, the degree of freedom in the arrangement of internal units can be made wider.</p> |
