Abstract
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.
