DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the present invention.
Here, a battery pack storage section 2 is formed on the back side of the mobile phone main body 1, and a battery pack 3 is mounted in the battery pack storage section 2 from obliquely above. Battery pack storage 2
On the rear end side, an engagement latch mechanism 4 for holding the battery pack 3 easily and detachably is provided. In addition, a locking concave portion 6 that engages with the front end side of the battery pack 3 is provided on the front end side of the battery pack storage section 2.

On the other hand, on the rear end side of the battery pack 3, a locking groove 5 for engaging with the engagement latch mechanism 4 of the battery pack housing 2 is provided.
The battery pack 3 is provided at its tip end with a locking projection 7 that engages with the locking recess 6 of the battery pack housing 2.

Further, on the side surface of the main body of the portable telephone in which the battery pack storage section 2 is located, a fall prevention lock section 8 is provided, and the fall prevention lock section 8 is provided on the bottom face of the battery pack 3 to prevent the fall. By fixing the nail 9,
The battery pack 3 is prevented from falling off.

FIGS. 2 and 3 are views showing the engagement latch mechanism 4, wherein the hooks 41 of the engagement latch mechanism 4 are shown.
Engages with the rear end side locking groove 5 of the battery pack 3.

The hook 41 is moved up and down by a shaft 43. Now, when the hook 41 is pushed down in the state shown in FIG.
Moves 90 degrees by moving along the guide 44 to reach the lowest point. Thereafter, when the hook 41 is pushed up by the restoring force of the coil spring 45, the pin 4
2 comes into contact with the latch claw portion 46, so that the state shown in FIG. 3B is reached, and the hook 41 is locked at the lower position.

The hook 4 is moved from the state shown in FIG.
When the hook 41 is pushed down, the pin 42 is rotated 90 degrees by the guide 44, so that when the hook 41 is pushed up, the pin 42 rises without contacting the latch claw portion 46, and as shown in FIG. As shown, the lock is released and the hook 41 is pushed up to the upper position. In this manner, the hook 41 is alternately positioned upward and downward each time the hook 41 is pressed.

Next, the operation when the battery pack is attached / detached will be described.

When the battery pack is to be mounted on the main body of the portable telephone, first, the locking projection 7 on the tip side of the battery pack 3 is engaged with the locking recess 6 of the battery pack storage 2, and the battery pack 3 is Push the rear end side toward the battery pack storage section. Assuming that the engagement latch mechanism 4 is in the state shown in FIG. 3A, the rear end portion of the battery pack 3 contacts the hook 41 of the engagement latch mechanism 4 and the hook 41 is pushed down. Go. When the bottom surface of the battery pack 3 is pushed down to a position where it comes into contact with the battery pack housing 2, the pin 44 of the engagement latch mechanism 4 rotates 90 degrees to reach the lowest point, and the hook 41 It engages with the locking groove 5 of the pack 3. Thereafter, when the pressing down of the battery pack 3 is stopped, as shown in FIG. 3B, the hook 41 is locked at the lower position, and the battery pack 3 is held in the battery pack storage section 2.

The hook 41 is locked at a position where the bottom surface of the battery pack 3 slightly rises above the surface of the battery pack storage section 2. When the hook 41 is pressed down again, the lock is released. There is a risk that the pack will fall off. In order to prevent such a battery pack from falling off, a drop-off prevention lock portion 8 is provided on a side surface of the mobile phone body 1.
And a drop-off preventing claw 9 is provided on the bottom surface of the battery pack 3. After the battery pack 3 is held in the battery pack storage section 2 by the hooks 41,
Is fixed by sliding the
The operation of the engagement latch mechanism 4 is stopped.

When the battery pack is to be removed from the body of the mobile phone, firstly, the captive lock portion 8 is slid in the opposite direction to release the engagement with the captive claw 9 of the battery pack 3. Is operable. Then, by pushing the battery pack 3 downward and pushing down the hook 41, the pin 42 of the engagement latch mechanism 4 is rotated 90 degrees to bring the lock release state. Thereby, the hook 41
Is pushed upward, the battery pack 3 is also pushed up, the hook 41 is released from the locking groove 5, and the battery pack 3 can be removed from the battery pack storage section 2. Such a battery pack attaching / detaching operation can be performed with one hand.

[0021]

As described above, according to the present invention, the rear end side of the battery pack housing provided in the main body of the portable telephone is provided with:
A latch mechanism having hooks that are alternately set upward and downward each time the button is pressed is provided, and the hook is engaged with a locking groove provided on the rear end side of the battery pack, so that the battery pack can be attached and detached. It can be easily done with one hand. In addition, by providing a claw for preventing the battery pack from falling off and providing a fixing means for fixing the claw to the main body of the mobile phone, it is possible to prevent the battery pack from falling off due to an impact or the like.
