Abstract
PURPOSE:To keep the originally set density characteristics uniform at every temperature, by carrying out the switching of the output of correction memory, which has been prepared in a multiple way for certain temperature steps, through the converted output, that is, the coded output of a temperature detector. CONSTITUTION:The production of pulses is started at a counter gamma CNT by a print start signal PS, and memory comprising correction values is prepared at a correction memory gamman ROM for obtaining the aimed characteristics in a multiple way for every certain temperature step. The correction output of the memory gamman ROM is subjected to parallel-serial conversion at a parallel-serial converter P/SMP, and is switched by multiplexer function at a certain temperature step to output gamma pulses to obtain the desired density characteristics. The output of the temperature detector T is amplified at an amplifier AMP, and is subjected to code conversion at a converter A/D in a multiple way in a certain temperature step, and its output is latched by timing of a signal PS to be used for switching the multiplexer.
