<p>PROBLEM TO BE SOLVED: To provide a register clutch controller for controlling a resist clutch on and off without influence by a processing time of a control-purpose micro processor. SOLUTION: A time from detection of an original tip signal by a transition dietector 6 until a turn-on time of a register clutch and a time from the turn-on time until turn-off time of the register clutch are recorded in offset registers 9a, 9b by a micro processor in advance. And, a capture register 13 takes in an output value of a timer count register 8 by the detection of the transition detector 6, and a control mode is set at a mode setting unit 12, and an offset selector 10 selects in a setting mode either of recorded times of the offset registers 9a, 9b. And then, an output latch circuit 17 outputs a clutch control signal by the output values of the capture register 13, offset selector 10, and timer counter 8, and a mode detection latch circuit 19 informs the micro processor of the mode. And, ON-OFF control of the register clutch is executed with a high precision without being influenced by processing of the micro processor.</p> |
