Abstract

An electronic instrument, such as a camera, which is supplied with electric power from a battery and selectively receives two kinds of batteries which are different from each other in shape and output voltage. A battery chamber of the electronic instrument is constructed to commonly receive the first and second batteries such that a space of the battery chamber is commonly occupied by parts of the first and second batteries. Additionally, a member is projected into the battery chamber and determines which kind of batteries is received. In response to the result of the determination, a voltage converting means converts the output voltage of the battery to a given voltage such that an electionic circuit of the electronic instrument operates with the optimum voltage condition with the voltage supplied from either one of the batteries which are different from each other in shape and output voltage.
