Signal processing apparatus.

摘要

An LED printer 21, after power-on, take steps a1 to a6 for preparation and then steps a7 to a9 for printing operation, as shown in Fig.28. In controlling the printing operation at step a9, the temperature of a fixing unit 46 is detected by a thermistor or the like. Collection of these various data is accomplished by providing a step for counting the number of executions of the operation in the operation executed every one-millisecond and by converting the number of executions thus counted into an elapsed time. The configuration of the processing apparatus is thereby remarkably reduced in size. <IMAGE>
