ABSTRACT:
To reset only the CPU in a component in an abnormal condition without affecting CPUs of components in a normal condition, a multi-component system, in which a plurality of components each including at least a CPU are connected via a common bus to each other, includes a first reset signal generating unit which generates a reset signal by a switch operation to send the reset signal to respective components and a judge unit which is disposed in each component to determine whether or not resetting of a CPU is allowed. The judge unit inhibits, if the CPU is in a normal condition, the resetting of the CPU in response to the reset signal and resets, if the CPU is in an abnormal condition, the CPU in response to the reset signal.
