Abstract

PURPOSE:To preheat a fluorescent lamp adequately before lighting and to prolong the service life of its tube, and to eliminate a waiting time by detecting preparatory operation for copying start and preheating the fluorescent lamp, and lighting the fluorescent lamp with a copying start signal. CONSTITUTION:The opening operation of an original cover 9 for placing an original on original glass 2 as preparatory operation for copying is detected by a magnet 21 fitted to the original cover 9 and a reed switch 22 which responds to the contacting/leaving operation of the magnet 21. The filament of the fluorescent lamp 10 is preheated with a detection signal of operation in a relatively early stage. Then when a mode selection key is operated and then a print key for the start of copying is operated, the fluorescent lamp 10 is turned on. Consequently, the fluorescent lamp is preheated neither too much nor too less simultaneously with power-on operation to prolong the life of the tube, and the waiting time for the preheating is eliminated.
