DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multifunctional handset of a terminal device in a digital mobile communication system, and more particularly, to a multifunctional handset capable of switching communication function services by an open / close structure.

[0002]

2. Description of the Related Art A conventional analog mobile communication system for business use is a main service of a simplex communication service, and a terminal device mainly has a microphone system and a speaker system of a press system. For this reason, digital business mobile communication systems in which new services are provided with the advancement of communication have a structure in which a press button switch is added to the telephone handset type in order to support duplex communication services. .
Specifically, an example of a terminal device in a conventional mobile communication system is described in Japanese Utility Model Publication No. 7-15222.

As shown in FIG. 1, a wireless telephone 10 has a receiver 12 electrically connected thereto.
2, a transmission button 14, a reception section 16, and a transmission section 18 are provided. Wireless telephone 10 and handset 12
Has a shape similar to that of a phone that is commonly found. The wireless telephone 10 has a function of switching between a simplex communication service and a duplex communication service inside, and the receiver 12 used for talking is different in usage depending on the simplex communication service and the duplex communication service. In the case of the duplex communication service, the handset 12 listens to the voice from the other party from the receiving part 16 in the same manner as a generally used telephone,
Used to speak from the transmission part 18. In the simplex communication service, the voice of the other party is heard from the reception monitor 20,
When transmitting, the transmission section 18 is pressed while pressing the transmission button 14. When the transmission button 14 is pressed, no sound is output from the reception monitor 20.

[0004]

In the terminal device described above, the operator has to hold down the press button when talking on the simplex communication service depending on the communication type. Therefore, there is a problem that it is difficult for an operator of the conventional analog communication system to operate the system, for example, forgetting to press the press button during a call.

Considering the above problems, for example, in a simplex communication service, a conventional analog communication system operator has a handset shape which is considered to be used by the operator, and has the same functions such as press talk. thing,
Also, in the duplex communication service, if the same usage method is used with the structure of a receiver of a general telephone, it is considered that the caller can smoothly transmit and receive without being confused.

Accordingly, an object of the present invention is to provide a multifunctional handset used for a terminal of a digital mobile communication system which provides two communication service functions of a simplex communication service and a duplex communication service, and which makes it easy to use the terminal. To provide a multi-functional handset.

[0007]

SUMMARY OF THE INVENTION According to the present invention, a handset of a terminal device has an opening / closing structure, so that when closed, a shape suitable for press talk is adopted and a microphone / speaker system is used. It has a structure similar to that of the handset. In addition, the communication mode is sensed when the handset is opened and closed to prevent erroneous operation. That is, the present invention relates to a multifunctional handset used for a terminal of a digital mobile communication system that provides two communication service functions of a simplex communication service and a duplex communication service. This makes it possible to easily switch between the simplex communication service and the duplex communication service.

[0008]

FIG. 2 shows an embodiment of the present invention.
This will be described with reference to FIG. Handset 22
Has a main body 26 and an opening / closing portion 28 rotatably supported by a hinge 30 on the main body. Opening / closing part 28
Can be opened and closed around the hinge 30. A microphone / speaker 24 is provided on the front of the main body 26. Further, a micro switch 32 capable of switching between two communication service functions is attached to the front of the main body 26. The micro switch 32 is turned on and off by opening and closing the opening and closing unit 28. A press button 34 is mounted on a side surface of the main body 26 so as to be able to switch between transmission and reception in a simplex communication service. The opening / closing section 28 is provided with a microphone 36 which is a microphone for transmitting when the duplex communication service is performed.
In addition, the handset 22 is electrically connected to the transmitting / receiving device 40 by a cord 38.

As shown in FIG. 2, by closing the opening / closing section 28 of the handset 22, the microswitch 32 is pressed and turned off, and is switched to the simplex communication service. In the simplex communication service, the microphone /
The speaker 24 can be used for transmitting and receiving. Press button 3 attached to the side of handset 22
4 allows the microphone / speaker 24 to be in a transmission state when the press button 34 is pressed, to talk the voice of the caller, and to be in a reception state when the press button 34 is released, so that the voice of the sender is output. It is designed to switch.

As shown in FIG. 3, when the opening / closing section 28 is opened,
The attached microswitch 32 is turned on to provide a duplex communication service. Microphone / Speaker 24
Acts as a speaker for duplex communication services,
You lose the role of the microphone. Press button 3
No. 4 is invalid in the duplex communication service. Therefore,
Even if the press button 34 is pressed by mistake, the voice of the other party can be output from the microphone / speaker 24. In the case of the duplex communication service, the handset 22 can communicate as if making a call with a general telephone.

As described above, the microswitch 32 is turned off when the opening / closing section 28 is closed, and turned on when the opening / closing section 28 is opened. Turn on / off the handset 2
By notifying the internal control unit 2, it is possible to switch to the simplex communication service and the duplex communication service, respectively.

As described above, when the communication mode is the simplex communication, as shown in FIG. 2, the communication unit is used with the opening / closing unit 28 closed.
The terminal device operates in the simplex communication mode by closing the opening / closing unit 28 of the handset 22. In the handset 22, when the opening / closing unit 28 is closed, the press button 34 is enabled, and when the breath button 34 is pressed, the transmission of the transceiver 40 is controlled and the transmission is turned on. The handset 22 is turned off when the press button 34 is not pressed, and the sound at the time of reception can be heard from the microphone / speaker 24. Further, when the communication mode is the duplex communication, as shown in FIG. 3, the handset 22 is used like a normal telephone with the opening / closing section 28 opened. When the handset 22 is open, the press button 34 is disabled. For example, even if the press button 34 is accidentally pressed during a call, the microphone of the receiver 24 does not cut off the voice of the sender. .

As described above, one embodiment of the present invention has been described in detail with reference to the drawings. However, the present invention is not limited to this embodiment, but may be modified and modified without departing from the gist of the present invention. Changes are possible. For example, the microswitch 32 can be provided not in the main body but in the opening / closing section.

[0014]

According to the present invention, the communication mode can be automatically switched by opening and closing the opening / closing section of the handset. When the opening / closing part is opened, the handset takes the shape of the handset of the telephone, and when the opening / closing part is closed, the operation at the time of communication is the same as that of the conventional analog type, so the operator presses the telephone when talking. This has the effect of preventing forgetting to press the button.
