专利汇可以提供Facsimile receiving system专利检索,专利查询,专利分析的服务。并且PURPOSE: To secure the automatic adjustment for the heat value of the heater by applying the power corresponding to the shift speed of the recording paper to the heating/fixing heater after counting the driving pulse of the secondary scanning step motor.
CONSTITUTION: The electrostatic latent image, which is formed by electrode 2 on recording paper 1 drawn out by roller 6 driven by secondary scanning step motor 5, is turned to a visible image via developer 3 and then fixed by heating/fixing heater 4. In this case, the frequency of the driving pulse applied to motor 5 corresponds to the shift speed of paper 1. Driving pulse (a) is counted (9) by the timing pulse generated at the zero-cross point of the commercial power source, and conduction time designation circuit 11 is controlled at the fixed counting value. And then AC switching circuit 12 is controlled by the output of circuit 11 to control the conduction time for heater 4. As a result, the power corresponding to the shift speed of paper 1 can be applied to heater 4.
