<p>A battery is prevented from being wrongly inserted into an image pickup device due to reduction of battery sizes. A mechanism for loading/unloading the battery (2) on/from the device (image pickup device (1)) whereupon the battery (2), which is a flat rectangular parallelepiped with a substantially square main plane, is removably mounted. On the both ends in a longitudinal direction on a rear plane opposing a plane inserting into the device, protruding sections (26, 27) are formed along the rear plane. Thus, even the flat rectangular parallelepiped battery (2) having the substantially square main plane can be prevented from being wrongly inserted into the device. The protruding section (27) has an inclined plane (271) inclined at an acute angle to the rear plane, and at the time of taking out the battery (2) from the device, the inclined plane (270) receives contact pressure from a locking means, and ejection of the battery (2) from the device is facilitated. The device is provided with a notched section (122) for exposing the other protruding section (26) when the battery (2) is loaded, and the battery is easily taken out.</p> |
