[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to portable radiotelephone equipment for use within the radio zone of a cellular or large zone configuration.

0002

2. Description of the Related Art Recently, the service area of cellular radio zones has been expanded for portable radio telephone devices, and the number of users thereof has increased.

[0003] A conventional portable radio telephone device will be explained below with reference to the drawings.

FIG. 3 is a block diagram of the configuration of a portable radio telephone device. In the figure, 1 is the main body of the device, which includes a control section 2, a radio section 3, a power source 4 using a battery, and the like. 5 is the antenna,
Reference numeral 6 denotes an operation section, 7 a speaker, 8 a microphone, and 9 a display section such as a liquid crystal display for displaying various information, which are integrated with the main body 1 of the apparatus.

FIG. 4 is a perspective view showing the general outline of a portable radio telephone device, in which (a) is an overall view, and (b) is an exploded view seen from the back side, with the antenna 5 shortened and the power source 4 removed. be.

In the conventional portable radio telephone device configured as described above, the antenna 5 is housed in the main body 1 of the device and carried around, and when necessary, the antenna 5 is pulled out and the display section 9 allows the call to be made at the site. After confirming the electric field strength, charging state of the power supply, etc., dial a call using the operation unit 6. The dialed input information is also displayed on the display section 9. After the called party goes off hook,
A call is started using the speaker 7 and microphone 8.

[0007] When a call is received, the operation unit 6 processes the call, connects the line, and starts talking with the caller.

[0008]

[Problems to be Solved by the Invention] However, portable radio telephone devices are generally used outdoors, and for example, when you want to talk in a moving car, you may want to know numerical information such as the telephone number of the other party or the opening time of a meeting. At that time, you have to stop the car to avoid danger and take notes, and there is a problem that it requires troublesome operations and time until you can make a call.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and provide a portable radio telephone device that stores numerical information such as a telephone number and time, and is capable of making automatic calls based on the stored numerical information.

0010

[Means for Solving the Problems] The present invention provides a mobile radio telephone device with a display section, DTMF (Dial Tone Mul
ti-Frequency) signal detection unit, a storage unit for the detection output of the DTMF detection unit, and an automatic dialing function, the received DTMF signal is displayed as numerical information on the display unit, or the DTMF signal is It is characterized by automatic dialing by directly using it.

[0011]

According to the present invention, necessary numerical information is stored and displayed in the portable radio telephone device, and when the displayed numerical information is a telephone number, it becomes possible to automatically dial that telephone number.

0012

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a configuration block diagram of a portable radio telephone device according to an embodiment of the present invention, and 1 to 9 are the same as or have the same functions as the conventional portable radio telephone device described above with reference to FIG. Other reference numerals include a storage section display button 10, a DTMF signal detection section 11, and a storage section 12 for storing the DTMF signal of the detection output.

FIG. 2 is a perspective view of a portable radio telephone device having the configuration shown in FIG. 1. The present invention has such an appearance, and this differs from FIG. This is the point.

The portable radio telephone device of the present invention constructed as described above operates as follows. First, when the user of the portable radio telephone device wants to make a call or receives a call, he or she can make a call in exactly the same way as in the conventional system. Then, while using the mobile radiotelephone device, some numerical information,
For example, if you need to obtain a phone number, time, etc.
The other party sends a DTMF signal as numerical information. The sent DTMF signal is detected by the DTMF signal detection section 11 and controlled by the control section 2 to be stored in the storage section 12 . Thereafter, the user of the portable radiotelephone device operates the storage section display button 10 at a convenient time. Thereby, the control unit 2 controls the display unit 9 to display the DTMF signal stored in the storage unit 12. Therefore, the user of the portable radio telephone device can record the information in a memo or the like later.

[0016] Furthermore, by providing an automatic dialing button for operating an automatic dialing function in addition to the storage section display button 10, when the DTMF signal sent from the other party is a telephone number, the use of the portable radio telephone device is made easier. When a person operates the automatic dialing button, the control section 2 controls the dialing automatically using the DTMF signal stored in the storage section 12. Therefore, a user of a portable radio telephone device can now immediately make a call and have a conversation even while driving, for example, without having to stop the vehicle.

[0017]

[Effects of the Invention] As explained above, the portable radio telephone device of the present invention can display and store numerical information without stopping operation no matter what condition it is in use. Since automatic calling is possible, it is convenient to use while traveling in a car.
