Battery accommodating chamber structure

摘要

A battery accommodating chamber structure includes: a battery chamber substantially in the form of a half cylinder and having a battery inserting opening through which a cylindrical battery is loaded in or unloaded from the battery chamber by moving it in a direction perpendicular to the axis of the battery chamber; and a battery lid pivotally coupled to the battery chamber through a shaft which is in parallel with the axis of the battery chamber, to open and close the battery inserting opening. In the structure, the shaft is so arranged that, when the battery lid is opened by turning it about the shaft, at least a part of the battery cover is caused to go into the battery chamber. The battery accommodating chamber structure is free from a difficulty that the battery lid is lost or damaged, and the battery can be readily removed from the battery chamber with simple structure.
