An electronic apparatus includes: a timer member that clocks time on the basis of the power supplied from a power source. A power supply member supplies the power to an electric motor of the electronic apparatus and to the timer member from the power source and interrupts the power supply thereto. A heat storage calculating member calculates heat storage of the electric motor and calculates heat storage of the electric motor after stop of the drive on the basis of the time clocked by the timer member. A controller controls the electric motor and controls the power supply member by initiating power-on and power-off operations. This is performed so as to, maintain the power supply to the timer member and the heat storage calculating member during a predetermined time, even after the power-off operation of the operation member.
