A connection terminal 17 is provided on the first engagement support piece 11 attached to the back side of the camera body 10. The connection terminal 17 is attached to the inner side surface 11a of the engagement support piece 11 so that fingers or the like do not come into contact with the connection surface of the terminal.

Therefore, when the battery device is attached to the video camera by sliding it in the direction of arrow B in FIG. 10, the battery device is attached to the engaging protrusion 22a of the first engaging step portion 22 of the battery main body 21. The inner side surface of the connection terminal 25 comes into contact with the connection terminal 17 provided on the inner side surface 11a of the engagement support piece 11, and the battery body 21 and the video camera 10 are electrically connected.

On the contrary, when the battery device is detached from the video camera, the lock projection 26 provided on the camera body 10 is operated by the lock member operating portion 27 to release the engagement with the lock recess 24, and the battery body is released. 21 to FIG.
It can be easily removed by sliding it in the direction of the medial arrow B.

When the battery device is attached to the external charging device 18 shown in FIG. 11, as shown in the drawing, the first engaging portion 19 and the second engaging portion 19 provided on the charging device 18 are provided. Charging can be performed by engaging an engaging portion (not shown) with the first engaging step portion 22 and the second engaging step portion 23 of the battery body 21 and electrically connecting them.

Next, in the battery device of this embodiment, the cutout holes 3 are formed in parallel in the rear side corner portion of the battery body 21 facing the first engaging step portion 22 as shown in FIGS. 6 and 7.
0 and 31 are provided, and a notch 32 is provided on the bottom surface 22b of the front engagement step 22 that faces the notch 30. Inside the battery main body 21 corresponding to these cutouts 30, 31, 32, a rotary body 33 having a substantially L-shaped plane is rotatably disposed with its substantially central portion pivotally supported. This rotating body 33 is provided with a colored display portion 34 at the end on the long side.

By the way, in the built-in type charging device 5 shown in FIG. 9, when the battery main body 21 is inserted and attached, the protruding portion 3 that engages with the notch 30 of the battery main body 21.
5 is formed. Although not shown, when the battery main body 21 is inserted and attached to the external charging device 18 shown in FIG. 11, a protruding portion that engages with the notch 30 of the battery main body 21, for example, L A protruding portion formed in a letter shape is formed.

Further, as shown in the drawing, a protrusion 37 that engages with the notch 31 is formed in the battery storage portion 2 of the built-in type video camera 1 according to this embodiment shown in FIG.

Therefore, when this battery device is attached to the charging device 5 shown in FIG. 9 for charging, as shown in FIG. 6, the rotating body 33 has the protrusion 35 formed on the charging device 5 on the battery body 21. While entering from the notch 30, pressing and rotating the rotating body 33 to expose the display portion 34 of the rotating body 33 from the notch 31, it becomes possible to recognize that this battery device is charged with electricity. The short piece side 36 of the rotating body 33 is made to project from the cutout portion 32.

When the battery device is attached to the charging device 18 shown in FIG.
A protruding portion (not shown) formed on the charging device 18 enters from the cutout portion 30 of the battery body 21 and presses and rotates the rotating body 33, so that the display portion 34 of the rotating body 33 is removed from the cutout portion 31. It is exposed, and the short piece side 36 of the rotating body 33 is projected from the cutout portion 32.

On the other hand, when the battery device is once attached to the electronic equipment, the display unit 34 is housed in the battery main body 21 so that it can be recognized that the battery device has already been used.

That is, when it is mounted on the built-in type video camera shown in FIG. 8, the protrusion 37 provided at the position corresponding to the notch 31 of the battery main body 21 in the battery storage unit 2 of the battery main body 21. Since it enters from the notch 31, the rotating body 3 in the battery main body 21
3 is pushed and rotated by the protruding portion, and the display portion 34 is housed in the battery main body 21.

When the external engagement type video camera shown in FIG. 10 is mounted, the first engaging support piece 11 abuts the short piece side 36 of the rotating body 33, and the rotating body 33 is shown in FIG. Since the display unit 34 is rotated as shown, the display unit 34 is housed in the battery body 21.

From this, the display section 34 is in a display state when the battery main body 21 is inserted into the charging device 5 and when it is attached to the video camera, that is, the notch on the side where the display section 34 is exposed. Since the position of the portion 31 changes, it is possible to recognize at a glance whether the battery device has just been charged or has been used by looking at the cutout portion 31.

The battery device according to the present invention can be applied not only to the video camera as described above, but also to any electronic equipment requiring the battery device. Further, if the battery device standard of the electronic device is unified, this battery device can be commonly used among different types of electronic devices without being influenced by the mounting method such as the built-in method or the external method.

In the case of the external type, if the engaging portions for attaching to the video camera have the same shape,
By enlarging the battery body 21 itself, the capacity of the battery device can be increased. At this time, as shown in FIG. 12, the lower end on the back side of the battery main body 21 has the same size as a normal battery device, and if only the upper side is enlarged, as shown in FIG. 13, the built-in system shown in FIG. The charging can be performed by the charging device 5 for the vehicle.
