Description

[Detailed Description of the Invention] The present invention relates to a battery storage device for equipment that uses a plurality of power batteries, such as electronic equipment with multiple functions.

For example, in a device that houses an electronic clock and a portable radio in the same housing, the electronic clock part uses a disc-shaped snap-button lithium battery, and the radio part uses a regular cylindrical single-cell battery. There is.

This is because if the power supply for the counter part is shared with the power supply for the radio part, even though the electronic clock does not consume much battery power, the radio part consumes a lot of battery power and the clock part soon becomes inoperable. , to avoid this.

The present invention is designed to store multiple batteries as described above in as small a space as possible, so that the watch battery, which is small and easy to lose, will not be lost when replacing the radio battery, which requires frequent replacement.
