发明名称 Safety load control apparatus and method
摘要 An image forming apparatus having a load control device which includes a load that executes a job, a relay that selectively connects the load with a power supply, and a central processing unit that outputs a plurality of control signals. Also included is an application specific integrated circuit that outputs a load driving signal to the load in response to a control signal sent from the central processing unit, an output condition observing device that observes an output condition of the application specific integrated circuit and a timer that counts pulses when the output condition is active and does not count pulses when the output condition is not active. In addition, the load stops driving when the timer has counted the prescribed number of pulses.
