An embodiment of the mobile communication device of the present invention will be described below with reference to FIGS.

As shown in FIG. 1, the mobile communication device is a mobile phone, and includes a device main body or a telephone main body 10 and an earphone microphone 20.

The telephone body 10 is a hollow box-shaped case 1.
1 is provided. At the top of the case 11, the antenna 12
However, a speaker 13 and a liquid crystal display
However, a push button 15 is incorporated near the center of the front, and a microphone 16 is incorporated at the lower part of the front. Although not shown, a printed wiring board and a battery are incorporated inside the case 11, and the printed wiring board is electrically connected to the antenna 12, the speaker 13, the liquid crystal display panel 14, the push button 15, and the microphone 16. .

The earphone microphone 20 includes an earphone 21, a microphone 22, and a cord 23. The earphone 21 and the microphone 22 are connected by a cord 23. In this portable telephone, the cord 23 is electrically connected to the printed wiring board via an automatic winding mechanism inside the case 11 of the telephone body 10. .

The automatic winding mechanism includes, for example, a reel,
It has a known structure including a spring for constantly rotating the reel in the winding direction, a latch mechanism for stopping the rotation of the reel by the spring at an arbitrary position, and the like. In FIG. 1, among these, only the button for releasing the latch mechanism is indicated by reference numeral 31. The cord 23 of the earphone microphone 20 is drawn into the inside of the case 11 from the hole 32 provided on the right side surface of the case 11, is wound around a reel of an automatic winding mechanism, and is electrically connected at its end to a printed wiring board. ing. The hole 32 is provided at the lower part on the right side of the case 11, and the release button 31 is located at the upper part of the hole 32 and protrudes outside from the hole provided on the right side of the case 11.

[0014] In this normal state of the mobile phone,
The cord 23 of the earphone microphone 20 is wound by an automatic winding mechanism incorporated in the telephone body 10, and the earphone 21 and the microphone 22 are located near the hole 32.

In carrying, the cord 23 of the earphone microphone 20 is stored inside the telephone body 10 and the earphone 2
1 and the microphone 22 are located near the bottom surface of the telephone main body 10, so that the portable telephone can be carried with the earphone
Not only does the “0” not disturb, but also when stored in a bag or the like, the earphone microphone 20 can be stored without worrying of being entangled or cut off by another cord 23 of the earphone microphone 20.

A telephone call with the telephone body 10 can be made by holding the telephone body 10 with a hand, arranging a speaker 13 at an ear, and arranging a microphone 16 at a mouth, similarly to a conventional portable telephone. At this time, the cord 23 of the earphone microphone 20 is drawn into the inside of the telephone main body 10, and the earphone 21 and the microphone 22 are located near the bottom of the telephone main body 10, so that the user has no special burden.
