Abstract
An equipment controller is disclosed that includes a CPU instructed to switch to a low power mode when being in a non-execution state. The equipment controller determines whether there is any execution task when the state of equipment switches to an energy-saving mode in which consumption power is reduced, and sets the interrupt cycle of a system timer of a real time OS that generates an interrupt for causing the CPU to awaken to be long if there is no execution task so that the CPU is caused to switch to the low power mode.
