Abstract

PROBLEM TO BE SOLVED: To replace a primary battery when it is consumed, and to replace a secondary battery when it is consumed or deteriorated. If it is an electric device with a complicated structure that takes time for this replacement work, the convenience of replacement is lost, and problems such as poor contact of electric contacts and disconnection of electric wires are likely to occur, and the design is deteriorated. In addition, when it is necessary to protect the electrical contacts such as dustproofing and waterproofing, it becomes a more complicated structure.
SOLUTION: A battery is inserted from the root part of a tripod.
