摘要

The handling in activating a function of stopping the operation of a driving component during the charging is improved as the prohibition of the operation of the driving component during the charging and the allowance of the operation of the driving component upon the end of the charging are automatically switched in accordance with whether there is power supply from the outside. A portable device 6 is arranged to include a secondary battery 3 , a driving component 5 driven by charged power of the secondary battery 3, a charging unit 112 configured to charge the secondary battery 3 by outside power, a transformation unit (processing unit) 124 configured to output the charged power of the secondary battery 3 at a driving voltage of the driving component 5, a detection unit 123 configured to detect the input of the outside power to the charging unit 112, and a switching controller 122 configured to switch the state of the transformation unit 124 from an operation state to a stopped state only when the input of the outside power to the charging unit 112 is detected by the detection unit 123.
