Filed: 2001-05-11
Abstract: PROBLEM TO BE SOLVED: To provide a device for driving a high voltage power source for paper transfer of which the stability of the output operation is enhanced. SOLUTION: A CPU(central processing unit) 1 captures outputs of various sensors and performs the control of the whole of a device such as the control of an optical writing and calculates and updates the driving condition of a high voltage power source at the interruption of a timer and drives a high voltage transformer 4 by making a pwm(pulse width modulation) generator 2 turn a switching transistor on/off with a necessary condition. An A/D converter 3 monitors an output to be applied to a high voltage output terminal and the CPU 1 repeats calculation and updating of the driving condition until timing that the high voltage output is stopped. A temperature sensor 5 is a sensor for grasping an environmental condition.  When a feedback value which is monitored in order to perform arithmetic control is changed largely when performing a continuous printing, it is detected that a recording paper is at a top end or a rear end and a calculation equation for updating the pwm calculation based on the duty of the pwm when applying a high voltage to a former page to perform the calculation and updating of the pwm. As a result, this driving device can follow up even abrupt load fluctuations by the top end and the rear end of the recording paper quickly and can ensure supply of proper amount of electric charge to enhance the quality of an image.
