专利汇可以提供Record control method专利检索,专利查询,专利分析的服务。并且PURPOSE: To realize the miniaturization and cost reduction for the power source in the thermal head type facsimile recording by securing a tone-type recording via the power source which features the periodic voltage change.
CONSTITUTION: Facsimile reception signal R is extracted for its tone level signal at control part 2' and then converted into the parallel signal every picture element through serial-parallel converter 5, and then decoded 6 to be supplied to registers 7a∼7g corresponding to each tone level. Power source 10 is divided into driving power source Ed for the thermal head and power source Eb for other parts. When the singular point of the AC waveform like OV is detected 11, counter 13 of driving buffer 8 and AR15 of fixed memory 16 are reset. The conduction data corresponding to the tone levels is memorized in memory 16, abd the conduction time is controlled for the thermal head in relation to the contents of the counter when the reception information is supplied and the characteristics of the recording paper.
