Thereby, the slide member 60 is slidably supported between the support plate member 64 and the rear panel 21D. The slide member 60 is always urged away from the connection terminal 56 by the elastic force of the coil spring 65. Thereby, the assembly of the mounting portion 44 is completed, and the rear panel 21D can be assembled.

  The attaching / detaching work of the battery device 1 to / from the mounting portion 44 configured as described above can be performed, for example, as follows. 9A is an explanatory diagram of the rear panel 21D when the mounting portion 44 is viewed from the front, FIG. 9B is a state when the insertion of the battery device 1 is started, and FIG. 9C is a locked state when the insertion of the battery device 1 is completed. It is explanatory drawing shown. 9B and 9C, the three engaging pieces 8a, 8b, 8c of the second engaging portion 8, the two hook pieces 62a, 62b of the second hook portion 62, and the second protruding piece 55b The engaging relationship of the three engaging pieces 7a, 7b, 7c of the first engaging portion 7 and the two hook pieces 61a, 61b of the first hook portion 61 and the first protrusion are configured symmetrically. Since the engagement relationship with the piece 55a is the same, the operation of one set (the first engagement portion 7 and the like) including the first engagement portion 7 and the like will be described here, and the other set (the second engagement portion 7 and the like). The description of the operation of the engaging portion 8 etc.) is omitted.

  First, a case where the battery device 1 is mounted on the mounting portion 44 will be described. In this case, as shown in FIG. 9B, the front portion of the battery device 1 on the output terminal 3 side is exposed to the lower side of the opening 45 of the mounting portion 44. And the 1st engagement piece 7a of the 1st engagement part 7 and the 1st engagement piece 8a of the 2nd engagement part 8 which were provided in the both sides of the width direction X of the 1st surface of the battery apparatus 1, The first protrusion piece 55a and the second protrusion piece 55b provided at both corners on the lower side of the opening 45 are engaged with each other so as to be hooked. In such an engaged state, the battery device 1 is rotated so as to approach the mounting portion 44 with the contact portion between the two projecting pieces 55a and 55b as the rotation center.

  Thereby, the second engagement piece 7b of the battery device 1 approaches the first hook piece 61a, the third engagement piece 7c approaches the second hook piece 61b, and the second engagement piece 7b becomes the first hook piece 61a. To touch. From this state, the battery device 1 is further rotated and pushed into the opening 45, so that the second engagement piece 7b connects the first hook piece 61a against the elastic force of the coil spring 65. Press and move to the terminal 56 side. And if the 2nd engagement piece 7b gets over the 1st hook piece 61a, the 3rd engagement piece 7c will contact the 2nd hook piece 61b next. When the third engagement piece 7c gets over the second hook piece 61b, the battery device 1 is completely inserted into the opening 45, and the lower surface portion 5a, which is the second surface of the battery device 1, is attached to the mounting portion 44. The bottom surface 45a which is the second surface is contacted.

Further, by pressing the operating portion 77b against the elastic force of the elastic member to retract the stopper portion 77a, the surface of the stopper portion 77a is pushed down to the same surface as the bottom surface portion 75a. Thereby, the battery device 1 can be moved in the longitudinal direction Y1.

  The attaching / detaching work of the battery device 1 according to the first embodiment of the present invention to the mounting portion 74 having such a configuration can be performed as follows, for example. 11A is an explanatory diagram of the rear panel 73 when the mounting portion 44 is viewed from the front, FIG. 11B is a state when the insertion of the battery device 1 is started, and FIG. 11C is a locked state when the insertion of the battery device 1 is completed. It is explanatory drawing shown. 11B and 11C, the three engaging pieces 8a, 8b, 8c of the second engaging portion 8, the two hook pieces 82a, 82b of the second hook portion 82, and the second protruding piece 55b The engaging relationship is such that the three engaging pieces 7a, 7b, 7c of the first engaging portion 7 and the two hook pieces 81a, 81b of the first hook portion 81 and the first protrusion are configured symmetrically. Since the engagement relationship with the piece 55a is the same, the operation of one set (the first engagement portion 7 and the like) including the first engagement portion 7 and the like will be described here, and the other set (the second engagement portion 7 and the like). The description of the operation of the engaging portion 8 etc.) is omitted.

  First, a case where the battery device 1 is mounted on the mounting portion 74 will be described. In this case, as shown in FIG. 11B, on the upper side of the opening 75 of the mounting portion 74 (on the side opposite to the connection terminal 56), the lower surface portion 5a of the battery device 1 is made to face the bottom surface portion 75a. Then, the battery device 1 is pushed in against the urging force of the stopper member 77, and the first opening 10a between the first engagement piece 7a and the second engagement piece 7b of the first engagement portion 7 is pressed. The first hook piece 81a of the first hook portion 81 is inserted into the first hook portion 81. At the same time, the second hook piece 81b of the first hook part 81 is inserted into the second opening 10b between the second engagement piece 7b and the third engagement piece 7c of the first engagement part 7. Thereby, the lower surface portion 5 a that is the second surface of the battery device 1 is brought into contact with the bottom surface portion 75 a that is the second surface of the mounting portion 74.

  In this case, the first discrimination recess 9a provided on the first step surface 6a of the battery device 1 is provided with the first hook provided on the first hook piece 81a of the first hook portion 81 in the same manner as in the above embodiment. The determination convex portion 53a is inserted. Similarly, in the third determination concave portion 13a provided on the second step surface 6b of the battery device 1, the second determination convex portion 54a provided on the first hook piece 82a of the second hook portion 82 is provided. Inserted. Then, the first determination convex portion 53 b provided in the second hook piece 81 b of the first hook portion 81 is inserted into the second determination concave portion 9 b provided in the first step surface 6 a of the battery device 1. Is done. Similarly, in the third discrimination recess 13b provided on the second step surface 6b of the battery device 1, a second discrimination projection 54b provided on the second hook piece 82b of the second hook portion 82 is provided.

That is, in this embodiment, the user presses the operation portion 77b to push down the surface of the stopper portion 77a of the stopper member 77 to the same surface as the bottom surface portion 75a against the urging force of the elastic body. From this state, the battery device 1 is slid until the four engagement pieces 7b, 7c, 8b, 8c are detached from the four hook pieces 81a, 81b, 82a, 82b. Thereby, the engagement state by the four engagement pieces 7b, 7c, 8b, 8c and the four hook pieces 81a, 81b, 82a, 82b is released, and the battery device 1 can be taken out. At this time, the output terminal 3 of the battery device 1 is peeled off from the connection terminal 56, and the electrical connection between the battery device 1 and the digital video camera 20 is released. Therefore, the battery device 1 can be taken out by pulling the battery device 1 away from the opening 75.
