PURPOSE:To control a device to be controlled without fail by generating the prescribed width pulse continuously when the control by the pulse control signal is unsuccessful. CONSTITUTION:A control deciding means 2 receives the control indicating signal from a control means 1, outputs the prescribed pulse, and judges, based upon this, whether the control of the device 6 to be controlled is executed within a constant time or not. A recontrol deciding means 3 sends the control instructing signal to the control deciding means 2 so that the control may be repeated at the prescribed number of times when the control unsuccessful signal is received from the control deciding means 2. Next, a pulse generating means 4 receives the control instructing signal from the control deciding means 2 and outputs the prescribed width pulse to the device 6 to be controlled. Thus, the control of the device to be controlled can be executed without fail. |
