As for 2c, the V-shaped tip 12d provided on one plate 12b is always in contact with the flat tip 12e of the other plate 12c by the urging force (see (a)).

The other plate 12c of the clip 12 is fixed to the back surface 11a of the telephone body 11, and the one plate 12b is pressed against the biasing force, that is, the other plate 12c of the telephone body 11. It can be separated from the back surface 11a (see (b)). When the force for separating the one plate piece 12b is removed, the one plate piece 12b is
Returns to the original parallel state, and the V-shaped tip 12c contacts the flat tip 12e (see (a)).

The width of the clip 12 is formed to be substantially the same as the width of the telephone body 11 so that the clip 12 can be securely inserted without falling down when the clip 12 is inserted into a holding object such as a waist belt. ing.

The clip 12 has a switch 14. The switch 14 includes a movable contact 14a provided substantially at the center of one of the plate pieces 12b and a movable contact 14a.
The fixed contact 14b is provided substantially at the center of the other plate piece 12c corresponding to a. The switch 14 includes, for example, a pair of contact terminals in which a fixed contact 14b is separated from each other. When the movable contact 14a contacts both contact terminals, both contact terminals are closed via the movable contact 14a and become conductive.

That is, in the normal state of the clip 12, in which the V-shaped tip 12d contacts the flat tip 12e, the contacts 14a and 14b contact and the switch 14 is turned on.

FIG. 2 is an explanatory diagram showing a portable state of the portable telephone of FIG. As shown in FIG. 2, when carrying the mobile phone 10, for example, the mobile phone 10 is mounted and held on the waist belt B by sandwiching the waist belt B of the mobile phone user H with the clip 12. The switch 14 of the mobile phone 10 mounted and held on the waist belt B is in an off state (see FIG. 1B).

Thus, the portable telephone user H can carry the portable telephone 10 directly without holding it in his / her hand, storing it in a bag or in a pocket of clothes, and without using a dedicated storage case. can do.

The mobile phone 10 can be mounted and held at any place other than the waist belt B, such as a pocket or a collar, as long as the switch 14 can be turned off by the clip 12. .

FIG. 3 is a flowchart showing the operation involved in using the portable telephone of FIG. As shown in FIG. 3, when the mobile phone 10 is not pinched by the clip 12, the switch 14 is turned on, a detection signal is input from the detection circuit 15 to the selection control circuit 16, and the numeric keypad 17
Is in the numeric keypad priority state in which the operation of (1) is prioritized (step S101).

In this state, the on-hook switch 17a and the off-hook switch 17b in the numeric keypad unit 17 can be used, and the on-hook switch 1 is activated by a ringing tone.
By operating the terminal 7a, the line can be connected, or the off-hook switch 17b can be operated after the end of the call to disconnect the line.

Next, the portable telephone 10 is attached to the waist belt B.
Is held (step S102). At this time, the mobile phone 10 sandwiches the waist belt B between the clips 12 (see FIG. 1B), and the detection circuit 15 does not output a detection signal. Since there is no input of a detection signal to the selection control circuit 16, the detection circuit 15
The operation is switched to the detection circuit priority state in which the operation of (1) is prioritized (step S103).

That is, the portable telephone 10 is attached to the waist belt B.
When the switch 14 is mounted and held (see FIG. 2),
Is changed from the on state to the off state, the detection circuit is in the priority state, and the numeric keypad section 17 does not function.

In this state, when a ringing tone is emitted,
The mobile phone user H tries to talk on the mobile phone 1
0 from the waist belt B (step S10).
4). When the mobile phone 10 is removed from the waist belt B and the clip 12 returns to the normal state, the switch 14 is turned on, and a detection signal is input to the selection control circuit 16.

At the time of this transition detection, since the ringing tone is generated, when the mobile phone user H removes the mobile phone 10 from the waist belt B, the ringing tone stops and the line is connected at the same time. The handset is set in a call-enabled state, and the state is switched to the numeric keypad priority state (step S105).

Then, the portable telephone user H talks on the detached portable telephone 10 (step S106), and after the termination of the call, operates the off-hook switch 17b to disconnect the line (step S107).

Thereafter, the mobile phone 1 is attached to the waist belt B.
It is determined whether or not 0 has been attached and held (step S10).
8). If the mobile phone 10 is mounted and held (Yes), the process returns to step S103 to switch from the numeric keypad priority state to the detection circuit priority state, and if the mobile phone 10 is not mounted and held with the mobile phone 10 removed (No), the process returns to step S101. Thus, the numeric keypad priority state is maintained.

FIGS. 4A and 4B show another example of a clip and a switch. FIG. 4A is an explanatory view of a clip having a curved tip, and FIG. 4B is an explanatory view of a switch in which a plate piece also serves as a movable contact.

As shown in FIG.
Has a curved end portion 20a instead of the V-shaped end portion 12d, and a tapered end portion 20b having a tapered open end instead of the flat end portion 12e. Thus, the clip 20 can be easily and smoothly inserted into the waist belt B or the like.

As shown in FIG. 4B, the movable contact of the switch is formed by deforming the open end of one plate 22a of the clip 22, and the plate 22a also serves as the movable contact. This simplifies the structure and facilitates manufacture.

As described above, according to the present invention, since the mobile phone 10 itself is mounted and held on the waist belt B, the mobile phone 10 can be taken out quickly and easily without taking up any space when carrying it. Further, when the mobile phone 10 is detached from the waist belt B, the receiver is put up, so that it is possible to promptly respond to the ringing tone and the ringing time is shortened.

That is, there is no need to take out the mobile phone 10 and no time is required from the time the ringing tone is issued to the time the call is answered. Don't worry about what you did.

Further, since the portable telephone 10 can be carried without using a dedicated storage case, there is no need to purchase a dedicated storage case suitable for the portable telephone.

In the above-described embodiment, the object to be sandwiched by the clip is not limited to the waist belt B, and various objects such as a back and a belt or a pocket of clothes can be inserted and held.
