Abstract
A battery-type power supply device realizes data transmission while also supplying power to a battery-driven external load device in a state in which the battery-type power supply device is mounted in a battery box of the external load device. The battery-type power supply device is mountable in the battery box of the external load device, has a shape and dimensions conforming to battery standards, and is capable of housing a small-size battery therein. An output transistor is interposed between a housed battery and an outer electrode terminal, and opening and closing of the output transistor are controlled by a PWM control section at a duty ratio corresponding to an instruction received from an external information processing device by a radio communication section, so that the battery type power supply device thereby functions as a switching power supply. Opening and closing of the output transistor are controlled by a transmission section in order to transmit data to the external load device through the outer electrode terminal. Connections of the transmission section and the PWM control section to the output transistor is switched by a connection switching section.
