A compact camera including one mounting board to which a plurality of electronic components are mounted. A display panel, a control unit, and a land portion, located underneath input devices, are mounted on an upper surface of the mounting board. A first drive IC and a second IC are mounted on a lower surface of the mounting board. Furthermore, a low-power device, such as an autofocus device, is mounted on a lower surface of the mounting board. The autofocus device is disposed near the input devices. Therefore, an inhibiting circuit is provided which inhibits the operation of the autofocus device when the input devices receive operation input signals.
