BATTERY HOLDER USED FOR RADIATION METER
Document Type and Number:
Japanese Patent JP2014179273
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To supply power even when all batteries are not attached to a battery holder which is used for a radiation meter and to/from which a plurality of batteries can be attached/detached.SOLUTION: When a battery is not attached to one of battery holding parts (10-1, 10-2), energization force is given from a helical spring 16 to a negative movable conductor 14, and the negative movable conductor 14 contacts a contact conductor 20. Thus, the negative movable conductor 14 is connected with a positive conductor 12 via the contact conductor 20 and a conducting wire 22, and a spring fixing conductor 18 is conducted with the positive conductor 12. When a battery 28 is attached to the battery holding part, a positive pole of the battery 28 contacts the positive conductor 12, and a negative pole of the battery 28 contacts the negative movable conductor 14. The battery 28 gives force to the helical spring 16 via the negative movable conductor 14, and shrinks the helical spring 16. Thus, the negative movable conductor 14 is separated from the contact conductor 16, and the spring fixing conductor 18 is blocked from the positive conductor 12.
