The present invention is directed to reliably prevent a trouble that a battery is loaded either in a state where a ribbon is entirely housed in a battery housing or without a ribbon by a simple method using a ribbon. Guide parts ( 83, 84 ) are provided on both side walls ( 57, 58 ) of a battery housing ( 53 ). A ribbon ( 81 ) is set so as to cross the battery housing ( 53 ) in a stretched state by the guide parts ( 83, 84 ) in a position where the battery can be taken out by drawing the ribbon ( 81 ). With the configuration, at the time of loading a battery, by making the ribbon ( 81 ) extend outside, the ribbon ( 81 ) is not entirely housed in the battery housing ( 53 ) or absence of the ribbon ( 81 ) in the battery housing ( 53 ) can be prevented. By making the battery front end face come into contact with the stretched ribbon ( 81 ) and inserting a battery, a normal loading state in which the ribbon ( 81 ) is pushed to the deepest place can be assured. The battery ejecting function with a simple ribbon ( 81 ) can be reliably displayed.
