It is configured.

Next, the operation of the battery holder 10 configured as described above will be described.
Storage Operation of Battery 2 When the battery 2 is not stored in the storage recess 12 of the battery holder 10, as shown in FIGS. 4 and 7 to 9, the engaging claws 1404 are biased by the first spring means 1407. The operating portion 1402D is positioned at the non-operating position by the biasing force of the second spring means 1407, and the operating portion 1602C is pressed by the biasing force of the third spring means 1407. Located in the locked position.
In this state, the engaging portion 1402E of the first operating member 1402 and the engaging portion 1404B of the engaging claw 1404 are engaged, and the second spring means 1407 keeps this state. It is energized.
Therefore, as shown in FIG. 10, even if the operation portion 1602C of the second operation member 1602 is slid from the lock position to the lock release position, the posture of the first operation member 1402 does not change, and therefore, When the finger is released from the operation unit 1602C that has been slid to the unlocked position, the second operating member 1602 is returned to the locked position by the third spring means 1604. That is, in a state where the battery 2 is not housed in the housing recess 12, the operation portion 1602 </ b> C of the second operation member 1602 does not stay at the unlock position but is located at the lock position.

When the battery 2 is housed in the housing recess 12 in this state, as shown in FIG. 5, the engaging portion 1010 is engaged with the engaging recess 202 of the battery 2, and the engaging claw 1404 is engaged with the engaging recess 204. Engaged. As a result, the battery 2 is housed and held in the housing recess 12. That is, the battery 2 is housed and held in the housing recess 12 by housing the battery 2 in the housing recess 12 without operating the first operating member 1402 and the second operating member 1602 at all.
At this time, the claw portion 1404C of the engagement claw 1404 contacts the bottom of the engagement recess 204, so that the engagement claw 1404 is displaced outward by the distance S as shown in FIG.
Accordingly, as shown in FIGS. 11 and 12, a gap S corresponding to the distance S is formed between the engaging portion 1402E of the first operating member 1402 and the engaging portion 1404B of the engaging claw 1404. The
That is, the first operating member 1402 is urged upward of the housing recess 12 by the first spring means 1406, but the upper surface of the second arm 1402C of the first operating member 1402 (directed upward of the housing recess 12). The first arm 1602A of the second operation member 1602 is positioned on the surface of the first operation member 1602A. Therefore, even if the engagement claw 1404 is moved by the battery 2, the first operation member is interlocked with the movement of the engagement claw 1404. 1402 is not oscillated and is maintained in the non-actuated position, which corresponds to the distance S between the engaging portion 1402E of the first operating member 1402 and the engaging portion 1404B of the engaging claw 1404. Thus, the gap S is formed.

Removal operation of battery 2 When removing the battery 2 from the housing recess 12 of the battery holder 10, as shown in FIGS. 13 and 4, the operation unit 1602C is slid with a finger to bring the second operation member 1602 into the unlocked position. Move.
When the second operating member 1602 is moved to the unlock position, the first arm 1602A of the second operating member 1602 is retracted from the upper surface of the second arm 1402C of the first operating member 1402. In this case, the first arm 1602A retracts from the upper surface of the second arm 1402C, and at the same time, the second arm 1402C has the engaging portion 1402E engaged by the urging force of the first spring means 1406 as shown in FIG. It swings until it comes into contact with 1404B. That is, the battery 2 swings by the gap S generated by housing the battery 2 in the housing recess 12.
Here, when the finger is removed from the operation portion 1602C, as shown in FIGS. 15 and 16, the second operation member 1602 tries to move to the lock position by the urging force of the third spring means 1604. Since the two arms 1402C are swung by the gap S, the front end of the main body portion 1602A abuts on the side surface of the second arm 1402C of the first operation member 1402, so that the second operation member 1602 is unlocked. Stay on.
In the unlocked position, the first arm 1602A located on the upper surface of the second arm 1402C is eliminated, so that the second arm 1402C can be swung above the receiving recess 12, and can be operated with a finger. When the portion 1402D is swung upward (when swung to the operating position), as shown in FIGS. 17 and 18, the first operating member 1402 is swung upward, and the engaging portions 1402E and 1404B are moved. The engaging claws 1404 are retracted toward the outside of the housing recess 12. Thus, the battery 2 is lifted from the bottom wall 1002 of the housing recess 12 by the action of the leaf spring 1012 and can be taken out from the housing recess 12.
If the upper part of the battery 2 is covered with a hand in this state and the battery holder 10 and the battery 2 are turned upside down as they are, the battery 2 comes off the housing recess 12 by its own weight and gets on the hand.

As described above, according to the first embodiment, when removing the battery 2 from the housing recess 12, the user moves the second operation member 1602 from the locked position to the unlocked position with one hand. Since the operation member 1602 remains in the unlocked position as it is, the first operation member 1402 is moved by the hand operating the second operation member 1602, thereby releasing the engagement state of the battery 2 with the housing recess 12. The battery 2 can be removed.
Accordingly, the unlocking operation by the second operating member 1602 and the disengaging operation of the battery 2 by the first operating member 1402 can be performed with one hand, so that the operation of removing the battery 2 from the housing recess 12 is simplified. This is advantageous, for example, when the battery 2 is exchanged with the other hand while holding the main body of the imaging apparatus 100 with one hand.
In the present embodiment, the operation units 1402D and 1602C of the first and second operation members 1402 and 1602 are arranged in close proximity to each other, so that the position of the hand is determined when operating these operation units 1402D and 1602C. There is no need to change, which is more advantageous in improving operability.
In addition, when the second operation member 1602 is in the locked position, the first operation member 1402 does not move even when an external force is applied to the first operation member 1402, thereby preventing the battery 2 from being inadvertently dropped. This is advantageous.
Further, the first arm 1602A of the second operating member 1602 moves forward and backward with respect to the swinging locus of the first operating member 1402, thereby preventing the movement of the first operating member that releases the battery engagement state. Therefore, since the number of parts constituting the lock mechanism 16 is small, the configuration is simplified, which is advantageous for cost reduction.

In the present embodiment, the imaging apparatus is exemplified as the electronic device, but the present invention is applicable to various electronic devices using a battery.
In the present embodiment, the battery holder that accommodates and holds the battery in the accommodation recess has been described. However, the present invention is naturally applicable to an adapter holder that accommodates and holds various adapters instead of the battery.
