5, and transmits a signal received by the antenna 4 to the control unit 25, while transmitting a signal transmitted from the control unit 25 from the antenna 4. The transmission / reception circuit 24 is connected to the lead wire 12 of the microphone earphone 2 and to the speaker 8 and the microphone 9 provided in the telephone body 1. The audio signal transmitted from the control unit 25 is bidirectionally connected to the control unit 25.
To the earphone and the speaker 8 on the main body side. on the other hand,
The audio signal transmitted from the microphone of the microphone earphone 2 or the microphone 9 on the main body side is transmitted to the control unit 25 side. The display control unit 7 includes the display unit 6 and the control unit 25.
In accordance with a display command signal from the control unit 25, the display unit 6 displays a sign indicating an incoming call, a telephone number at the time of calling, a level and a numerical value at various settings, and the like.

The control unit 25 performs signal processing, transmission / reception operation of the portable telephone, data processing for various settings, display control, and the like, and a count transmitted when the cord 3 of the microphone / earphone 2 is pulled. According to the data of the number, control is performed by going off-hook to shift to the call mode or on-hook to end the call. In addition, the level of the ring tone output from the sounder at the time of an incoming call is adjusted in accordance with the count number data, and the ring tone is emitted from the speaker 8 at an appropriate volume.

Next, an example of use of the portable telephone will be described. First, the user inputs and sets in advance the off-hook timing at the time of an incoming call, the volume of a ring tone, and the like. When setting the off-hook timing, the user enters the off-hook initial value setting mode with the menu key 5d, and then inputs the initial value of the count number while looking at the screen of the display unit 6 with the up / down key 5e. As the initial value, when the user pulls out the cord 3 with the mobile phone stored in the pocket, and at a position where the microphone earphone 2 can talk,
For example, 30 times are input. When the mobile phone is stored in the bag, the initial value of the count is input as 40 times. When the numerical value is input in this way, the data is stored in the memory 22.

When setting the ringtone, the mode is set to the ringtone setting mode by the menu key 5d, and then the volume is set while looking at the screen of the display unit 6 by the up / down key 5e and the volume adjustment key. In this case, while the count number is displayed by the up / down key 5e, the volume adjustment key is operated and the set key 5 is displayed when the volume level is displayed.
When f is pressed, data of the volume level is set corresponding to the data of the count value. Here, the volume level is set to be high when the count value is large, and to be low when the count value is small, so that the ring tone varies depending on the storage position of the mobile phone. In this example, the ringing tone is set to be silenced when the count is 25, which is 30 when the off-hook timing is set, or 35 before the count is 40. Further, the ringing tone is made to gradually decrease from the start of counting until the count reaches 25 times. The off-hook termination is set by a value obtained by adding, for example, five counts to the count at the time of setting the off-hook timing.

When the user uses the portable telephone, the microphone earphone 2 is put into a pocket or a bag with the microphone earphone 2 pulled out from the telephone body 1 to a certain extent, so that the microphone earphone 2 can be easily taken out from the pocket or the bag. If there is an incoming call when the mobile phone is put in the pocket, a ring tone is emitted from the speaker 8. At this time, when the user pulls the cord 3, the rotating plate 14 provided on the take-up reel 11 rotates, so that a detection signal is sent from the photo sensor 18 to the pulse generator 19. This pulse generator 1
Numeral 9 sends a pulse signal indicating the rotation state of the rotary plate 14 to the counter 20 according to the detection signal. This counter 2
0 outputs the count value data corresponding to the number of pulses to the control unit 25 upon receiving the pulse signal.

The control unit 25 compares the data of the count value with the set value of the memory 22 after the count is started, and controls the sounder until the set value is reached, so that the ring tone from the speaker 8 is output. It is made smaller gradually. Then, the pull length of the cord 3 increases, and the count value 2
At five times, the ring tone from the speaker 8 is muted. Further, the call connection circuit is turned off-hook when the microphone earphone 2 is at a position where a call can be made 30 times. This allows
The user can talk without taking out the mobile phone, but since the ring tone is gradually reduced and the sound is muted before off-hook, there is no problem of disturbing the surrounding noise.

On the other hand, if there is an incoming call when the user keeps the mobile phone in the bag, the ring tone from the speaker 8 is made louder because the initial value is larger than that of the pocket. Therefore, even if the user is in a distant place, he / she notices the incoming call, and can pull out the code 3 and respond to the incoming call without any trouble as described above. Then, when the user ends the call, the code 3 may be further pulled and added to the previous count value, and the control unit 25 causes the call connection circuit to go off-hook. In the above embodiment,
Although the example of the mobile phone has been described, it is needless to say that the mobile phone can be widely applied to various mobile communication devices such as PHS.

[0019]

As described above, according to the first aspect of the present invention, when the cord connected to the microphone / earphone is pulled, the rotating plate rotates, and the count value of the number of rotations transmitted from the counter is obtained. The connection of the telephone line is controlled in accordance with the above data, so that it is possible to communicate with the microphone earphone without removing the telephone body from the pocket or the bag, and the usability is greatly improved. Also, since the connection of the telephone line is controlled simply by counting the number of rotations of the rotating plate linked to the take-up reel, the mechanism is greatly simplified and the production is easy compared to the conventional system. In addition, there is an effect that the manufacturing cost is reduced. In addition, the invention according to claim 2 changes the ring tone from the ring tone notifying means when the count number reaches a predetermined value, so that the pull length of the code and the count number correspond to each other, There is an advantage that the ring tone can be varied between large and small depending on the pulling length.

Further, according to the third aspect of the present invention, when the count reaches a predetermined value, the ring tone from the ring tone notifying means is muted. Has the advantage of eliminating the problem of disturbing noise when answering an incoming call. Further, the invention according to claim 4 changes the ring tone from the ring tone notifying means in accordance with the initial value of the memory, so that the length of the cord arbitrarily pulled out is set as the initial value of the memory.
When the cord is long, the phone body is stored in a bag or the like and the ring tone is increased.When the cord is short, the phone body is put in the pocket and the ring tone is reduced. There is an advantage that a ringtone can be heard at a volume. According to the fifth aspect of the present invention, when the count value of the counter is larger than the initial value of the memory, the ring tone from the ring tone notifying means is increased.
There is an advantage that the user can respond without missing a ring tone when the device is located in a distant place. Further, in the invention according to claim 6, since the setting means for setting the initial value of the memory is provided in the telephone main body 1, the user can set the initial value of the memory arbitrarily and use it in a convenient manner for the user. There are advantages that can be.
