Abstract:
A battery-powered apparatus which makes it possible to perform battery check with accuracy irrespective of whether a battery is used as an internal battery or an external battery and make the end voltages of the internal battery and the external battery coincide with each other. It is determined whether the battery or an accessory having the battery incorporated therein has been attached to the apparatus, and a predetermined voltage threshold level is set based on the determination result. The voltage value of the battery or the accessory having the battery incorporated therein is detected, and the detected voltage value and the voltage threshold level are compared with each other to decide whether or not it is possible to drive the apparatus.
