PURPOSE:To eliminate inconvenience of providing a spare holder for a primary battery separately by furnishing a primary battery holder in a single piece with a secondary battery externally fitted to an electronic apparatus. CONSTITUTION:As a power supply, a primary battery 26 is accommodated in a single piece with a secondary battery 20 externally fitted to an electronic apparatus. The primary battery 26 is accommodated while embraced by receipt plates 22, 22 and an elastic belt 24. Each receipt plate 22 can be opened and closed round a shaft 22A. The primary battery 26 is coupled parallelly with the secondary battery 20 through a contact 22B, and between them a diode 28 is installed. Accordingly the primary battery 26 provided for exhaust of secondary battery 20 does not require any special holder to permit simple accommodation. |
