HARDWARE DEVICE CONTROLLER, IMAGE FORMING APPARATUS, AND CONTROL METHOD

摘要

A hardware device controller includes a controlling unit, a relay unit, and a watchdog timer. The controlling unit outputs a control signal to control a hardware device. The relay unit outputs, on the basis of the control signal, a control signal to the hardware device. When not receiving a first signal output from the controlling unit via the relay unit for a predetermined length of time or longer, the watchdog timer outputs a second signal. When the second signal is output, the controlling unit and the relay unit perform initialization process, and the hardware device stops driving.

1. A hardware device controller comprising:
a controlling unit configured to output a control signal to control a hardware device; a relay unit configured to output, on the basis of the control signal, a control signal to the hardware device; and a watchdog timer configured to, when not receiving a first signal output from the controlling unit via the relay unit for a predetermined length of time or longer, output a second signal, wherein when the second signal is output, the controlling unit and the relay unit perform initialization process, and the hardware device stops driving.
