 An embodiment embodying the present invention will be described below with reference to FIGS. As shown in FIGS. 1 and 2, a communication circuit 2 is built in the main body 1 which constitutes the handset. The communication circuit 2 is adapted to be operated by a power supply from a battery pack 4 mounted in a battery housing portion 3 formed on the back surface of the main body 1.

A claw portion 5 is formed on the lower portion of the battery housing portion 3. Further, a guide hole 6 which constitutes a substantially L-shaped permitting means is formed through the rear surface of the main body 1. Inside the guide hole 6 (on the left side in FIG. 1), a main switch 7 composed of a slide switch shown in FIG. 3 is fixedly arranged.

The operating portion 7a of the main switch 7 can be switched between two positions, an "ON" position and an "OFF" position. When the operation unit 7a is in the "ON" position, the communication circuit 2 is held in an operable state when power is supplied, and when the operation unit 7a is in the "OFF" position. The communication circuit 2 is held in an inoperable state.

As shown in FIGS. 1, 2 and 7, a lock member 8 is provided between the guide hole 6 and the main switch 7. As shown in FIGS. 4 to 6, the lock member 8 is formed so as to have a plate-shaped restricting portion 8a, a claw portion 8b projectingly formed on the lower surface of the center of the restricting portion 8a, and a front surface of the restricting portion 8a. , And an operation portion 8c protruding outward from the guide hole 6.

A vertically long groove 8d is formed on the back surface of the restriction portion 8a. Then, as shown in FIGS. 1 and 7, the operation portion 7a of the main switch 7 is engaged with the groove 8d. Therefore, the lock member 8 is in a state of being vertically movable relative to the operating portion 7a. A spring S is arranged above the lock member 8, and the lock member 8 is always urged downward by the urging force of the spring S.

Further, the operating portion 8c of the lock member 8 can be moved along a switch operation passage 6a extending in the lateral direction of the guide hole 6 and a lock passage 6b extending in the vertical direction of the hole 6. It is like this.

When the operating portion 8c is moved to one side along the switch operating passage 6a, the operating portion 7a of the main switch 7 is changed from the "ON" position to the "OFF" in conjunction with the movement. It is designed to switch to the position. Further, when the operating portion 8c is moved to the other side along the switch operating passage 6a, the "OFF" position is switched to the "ON" position.

When the operating portion 8c of the lock member 8 is moved up and down along the lock passage 6b, the operating portion 7a of the main switch 7 is held in the "OFF" position, Only the lock member 8 moves up and down. That is, since the concave groove 8d of the lock member 8 with which the operation portion 7a of the main switch 7 is engaged is formed vertically long, when the lock member 8 is moved up and down, the lock member 8 is operated. It is adapted to move up and down relative to the working section 7a. Further, when the lock member 8 is at this position, the pawl portion 8b is held by the biasing force of the spring S so as to project downward from the inner upper surface of the battery housing portion 3. On the other hand, when the operating portion 8c is above the lock passage 6b against the biasing force of the spring S, the claw portion 8b is accommodated in the main body 1.

As shown in FIGS. 1 and 2, the battery pack 4 is configured by housing a plurality of batteries 10 in a box-shaped case 9. A cover (not shown) is welded to the inner surface of the case 9 by ultrasonic welding, and the battery 10 is covered with the cover.

On the lower surface of the case 9, there is formed a concave portion 11 that engages with a claw portion 5 formed in a lower portion of the battery accommodating portion 3. Further, a laterally long groove 12 is formed on the upper surface of the case 9. The recessed groove 12 is a groove that engages with the claw portion 8b of the lock member 8 provided in the main body 1 when the battery pack 4 is stored in the battery storage portion 3.

When the battery pack 4 is attached to the main body 1, the electrode plate of the battery pack 4 and the electrode plate of the main body 1 (both not shown) are connected, and the power source from the battery pack 4 to the main body 1 is connected. Supply becomes possible.

Next, the operation of this embodiment will be described. First, a description will be given of mounting the charged battery pack 4 on the main body 1. First, the claw portion 5 formed in the lower portion of the battery housing portion 3 is engaged with the concave portion 11 of the battery pack 4. Then, the battery pack 4 is brought into contact with the inclined surface of the claw portion 8b, and the lock member 8 is moved upward against the biasing force of the spring S.

When the battery pack 4 is accommodated in the battery accommodating portion 3, the lock member 8 moves in the lock passage 6b of the guide hole 6 by the biasing force of the spring S, as shown in FIGS. 9 and 10. Moved down. That is, the claw portion 8b is engaged with the recessed groove 12 of the battery pack 4, and the battery pack 4 is held in a state in which it does not come off the main body 1.

At this time, even if the electrode plates of the main body 1 and the battery pack 4 are connected, the power is not supplied to the communication circuit 2 because the operation portion 7a of the main switch 7 is not in the “ON” position. Therefore, in order to supply electric power to the communication circuit 2 to bring the mobile phone into a communicable state, the operation portion 8c of the lock member 8 is moved to the right side, as shown in FIGS. As a result, the operation unit 7a of the main switch 7 is also moved to the "ON" position in conjunction with it, and the communication circuit 2 is supplied with power from the battery pack 4 to keep the mobile phone in a communicable state.

In this state, the operation portion 8c of the lock member 8 cannot be moved upward due to the restriction of the switch operation passage 6a of the guide hole 6, and the claw portion 8b does not come off from the concave groove 12. .

When the battery pack 4 is replaced, when the battery pack 4 is removed from the main body 1, the above operation is reversed. As described above, according to the mobile phone of this embodiment, the lock member 8 and the operating portion 7a of the main switch 7 are connected to each other, and only when the operating portion 7a is in the off position where the communication circuit does not operate. The lock member 8 is allowed to move up and down, and the claw portion 8b of the lock member 8 is disengaged from the groove 12 of the battery pack 4.

Therefore, in the present embodiment, unlike the prior art, when the mobile phone is held in a communicable state, that is, the operation portion 8c is in the switch operation passage 6a and the operation portion 7a of the main switch 7 is " When in the “ON” position, the battery pack 4 cannot be removed from the main body 1.

As a result, the battery pack 4 cannot be removed from the main body 1 during standby of a received radio wave, during a call, or the like, so that reliability during communication can be improved. The present invention is not limited to the above-described embodiment, and the main switch 7 and the lock member 8 may be provided on the battery pack 4 side without departing from the spirit of the invention.
