摘要： A power source unit for an image recording apparatus having a CPU which controls an operation sequence of a load, includes a current sensor and a relay. The current sensor senses a load current. The relay is connected to a supply path to the load. The relay is operated to interrupt the supply path to the load when the CPU determines that the load current sensed by the current sensor exceeds a current limit value which is determined in advance for every operation cycle of the unit.

摘要： A braking system for image forming apparatus returns an optical scan system in the image forming apparatus to a preselected home position after each scan of a document placed on a platen, within a predetermined period of time. Various factors including temperature, the number of copies of the document previously made, can change the operating performance of the braking system so that it does not return the optical scan system to the home position within the predetermined period. Detectors are provided to detect and sense the factors which will change the operating performance of the braking system. Brake control apparatus is responsive to the detectors and controls the braking system to return the optical scan system to its home position within the preselected period of time to thereby maintain the efficiency of the braking system even as the factors such as temperature, and number of copies previously made changes during operation of the image forming apparatus.

摘要： A fail-safe apparatus for an image forming apparatus includes a central processing unit (CPU), a drive section or load, a disconnecting circuit, and a watchdog circuit. The CPU controls an image forming sequence. The drive section or load is controlled by the CPU through an input-output controller. The disconcerting circuit disconnects power supply to the drive section or load upon reception of a trigger signal. The watchdog circuit monitors an operation of the CPU so as to output a reset signal to the CPU and the input-output controller upon detection of an operation abnormality, and to output the trigger signal to the disconnecting circuit.
