Abstract
Abstract In a battery case mounting structure for electronic equipment, a battery case has a battery for supplying power to an electronic equipment. The electronic equipment has a main body provided with a mounting portion on which the battery case is to be mounted. A recessed portion is formed in the battery case. A locking projecting body is formed on the main body of the electronic equipment and inserted in the recessed portion to fix the battery case to the mounting portion. A guide portion supports the locking projecting body to be projectable from or retractable into the recessed portion so that the battery case is attachable to or detachable from the main body. A spring mechanism constantly biases the locking projecting body to project. An operating portion slides the locking projecting body to retract against a biasing force of the spring mechanism. Two terminals formed in the recessed portion are electrically connected to electrodes of the battery. Two different terminals formed on the locking projecting body come into electrical contact with the terminals formed in the battery case respectively and are electrically connected to an operating circuit of the electronic equipment when the locking projecting body is inserted in the recessed portion of the battery case.
