PURPOSE:To prevent the power source of an electronic apparatus from becoming unable to switch from one source to another due to the trouble of a switch or loss of dismounted batteries by switching the electric source and voltage through the exchange of a battery lid covering a battery containing part. CONSTITUTION:An outer case 1 is formed with an upper case 1a and lower case 1b on an electronic apparatus, a chamber 3 is provided in the case 1 for containing at least two batteries B1, B2, and a battery lid 4 is provided to cover an opening 2 of the chamber 3. The battery lid 4 is made so as to automatically switch the electric source and voltage by exchanging the lid 4 with another lid. For example, a contact base 41 is formed on the center of back surface of the battery lid 4, and a contact plate, by which batteries B1, B2, may be connected in series or in parallel, is provided on the contact base 41. |
