摘要
Based on the operation of a motor driver (16), a counter (13) makes an addition to and a subtraction from a heat generation counter value which is stored in a storage (14) and represents the temperature variation of a motor (7) and/or the motor driver (16). Once a switching decider (12) decides that a shift has been made from a normal operation mode, in which operating power is supplied, to a sleep mode which has a lower power consumption than that in the normal operation mode, a power source controller (15) refers to the heat generation counter value; and, when the heat generation counter value is equal to or more than a specified threshold value, the power source controller (15) stands by until the counter (13) makes a subtraction from the heat generation counter value to the threshold value and then shifts to the sleep mode.
