Battery mounting structure for power source section of electronic apparatus
 In a miniature electronic apparatus, a battery mounting structure includes a flat battery chamber formed in the casing of the apparatus and having an opening in the upper portion thereof. A lid is rotatable about pins to selectively open or close the opening of the battery chamber. A pair of rails are provided on the inner periphery of the lid in order to support a disk-like battery. To limit the rotatable range of the lid, stops are provided on the lid and respectively received in stop grooves formed in the walls of the battery chamber. Lock pawls extend out from the lid and mate with lock grooves formed in the walls of the battery chamber. When the lid is in an open position, the battery can be loaded in the apparatus. When the lid is in a closed position, it closes the battery chamber. Such a structure facilitates the loading and unloading of the battery while preventing the constituent parts of the apparatus from being lost or damaged by accident.
