Filed: 1989-05-29
Abstract: PURPOSE:To noiselessly operate the image recorder by providing a control means which switches a cooling fan from a low speed to high speed ventilating operation when the set number of recording papers exceeds a reference value. CONSTITUTION:Data on the set number of papers from a device 21 which sets the number of copy papers is taken into a control part 22 composed of a microcomputer; the cooling fan 12 is switched between the high speed and low speed ventilating operations according to the set number of papers, A. When a power source is first turned on, the cooling fan 12 starts the low speed ventilation thus, comes to a normal idling operation.
