A lock releasing member for moving the engaging claw in the unlocking direction to a position where the engagement can be released by the tapered surface.

In order to achieve the above-mentioned object, the second invention of the present invention is such that the claw portion projects from the battery mounting surface of the VTR camera body and is arranged so as to be movable in the locking and unlocking directions. First and second engaging claws that respectively engage with the formed hook-shaped first and second engaging parts, the second engaging part and the second engaging claw when a battery is mounted. First and second engaging claws, which engage with the claw portions of the first and second engaging claws, and first and second biasing springs that bias the first and second engaging claws in the locking direction, respectively. And a lock releasing member for moving the first engaging claw in the unlocking direction to release the engagement between the first engaging part of the battery and the claw part of the first engaging claw. It is characterized by that.

[0009]

According to the first aspect of the present invention, when the battery mounted on the battery mounting surface of the VTR camera body is to be removed from the VTR camera body, first, the engaging claw is attached to the biasing spring by the unlocking member. The engaging portion of the battery and the claw portion of the engaging claw are engaged with each other on the tapered surface by moving in the unlocking direction against the force. Next, when the battery is pulled in the detaching direction, the engaging part presses the claw part of the engaging claw and the engaging claw moves in the unlocking direction, so that the engaging part engages with the claw part of the engaging claw. Is released and the battery comes off the VTR camera body. That is, the battery is V if it is not pulled.
It does not come off from the TR camera body.

According to the second aspect of the present invention, the VTR
Replace the battery mounted on the battery mounting surface of the camera body with V
When detaching from the TR camera body, first, the lock releasing member moves the first engaging claw in the unlocking direction against the urging force of the urging spring, and the first engaging portion of the battery and the first The engagement of the engaging claw with the claw portion is released. Next, when the battery is pulled in the detaching direction, the second engaging portion presses the claw portion of the second engaging claw, and the second engaging claw moves in the unlocking direction. The part is disengaged from the claw part of the second engagement claw, and the battery is detached from the VTR camera body. That is, the battery is V if it is not pulled.
It does not come off from the TR camera body.
