Printer

摘要

The disclosure discloses a printer including a load circuit, a controller, a power receiving terminal, a first switching circuit, and a second switching circuit. The controller is configured to control voltage supply to the load circuit, and is connected to an input part. The power receiving terminal is configured to be connected to a power feeding terminal of an external power source device. The first switching circuit includes a first switch element configured to switch between conduction and interruption in accordance with a first control signal input from the controller, and is connected between the power receiving terminal and the input part. The second switching circuit includes a second switch element configured to switch between conduction and interruption in accordance with a second control signal input from the controller, and is connected between the battery storage part and the input part.
