Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite portable device, and more particularly to a radiotelephone device with a radio in which a radio is integrated with a radiotelephone device.

[0002]

2. Description of the Related Art Conventionally, portable radios and portable telephones (wireless telephone devices) have been widely used outdoors as broadcasting and communication media. Each functional block is shown in FIGS. In the portable radio of FIG. 3, the antenna 2
The weak radio wave input from 1 is amplified by the reception front end 22 that acts as a reception wave amplification unit, and further, the signal from the local oscillator of the synthesizer unit 23 is mixed to create an intermediate frequency of a desired broadcasting station, and detection is performed. The part 24 extracts the original audio signal. The radio can be heard by amplifying this signal in the baseband processing unit 5 and sounding the speaker 6. The control of the entire radio is performed by the control unit 7. A display unit 8 displays a tuning frequency and the like. An operation unit 9 performs tuning, volume adjustment, and the like.

In the radio telephone apparatus of FIG. 4, the receiving side outputs sound to the speaker 6 in the same manner as the portable radio of FIG. 1, 2, 3, 4 are 2 of the portable radio shown in FIG.
An antenna, a reception front end, a synthesizer section, and a detection section corresponding to 1, 22, 23, and 24, respectively. On the transmitting side, first, the input sound from the microphone 10 is converted into an electric signal, amplified by the baseband processing unit 5, and then modulated by the modulation unit 1.
Input to 1. Here, a carrier wave is received from the synthesizer unit 3, mixed and modulated, amplified to a specified output by a transmission front end 12 that acts as a transmission wave amplification unit, and passed through a bandpass filter 13 that divides a transmission / reception signal by a frequency and an antenna. 1 is transmitted as a radio wave. Further, 7 is a control unit, and 8 is a display unit, which displays a telephone number, the state of the device, and the like. An operation unit 9 is used for making a call and inputting a telephone number. In the case of a wireless telephone device, transmission / reception frequency selection is usually performed automatically between the base station and the wireless telephone device. In the above description of each unit, the baseband processing unit 5, the speaker 6, and the microphone 10 are collectively referred to as an audio processing unit, and the blocks from the detection unit 4 or 24 and the modulation unit 11 to the antenna 1 or 21 are collectively referred to as a high-frequency processing unit. Can be called.

[0004]

Both the portable radio and the wireless telephone device as described above have been miniaturized, and have been accepted and widely spread as having high utility value. But,
These are manufactured and used as individual products, and there is a problem that each product must be carried if one wants to use both.

The present invention has been made in order to solve the above-mentioned problems, and provides a radio telephone device with a radio by assembling components that can be used as common parts in a portable radio and a radio telephone device. Has a purpose.

[0006]

In a radiotelephone device with a radio according to the present invention, a control unit, a voice processing unit, a display unit, and an operation unit of the radiotelephone device and a portable radio are configured to be common at least, and modulated. A high-frequency processing unit above the detection unit is provided in each of the wireless telephone device and the portable radio, and a common control unit is equipped with a microcomputer that controls the entire device, and the wireless telephone device and the portable radio are in the same housing. It is constructed integrally.

[0007]

In the present invention, since the radio frequency processing section of the radio requires less space, portability is not impaired.
You can use the radio and telephone with one device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIG. FIG. 1 shows an embodiment of a functional block diagram of a radio telephone device with a radio. 1, the same reference numerals as those in FIGS. 3 and 4 denote the same components, and the baseband processing unit 5, the speaker 6, the control unit 7, the display unit 8, and the operation unit 9 are common parts for the radio and the telephone. Are using. Although not shown, of course, the housings are common and only one is provided. Reference numerals 31 and 32 are changeover switches for switching between the radio and the telephone, which are interlocked with each other. That is, the changeover switch 31
1 to the radio side (state shown in FIG. 1), the changeover switch 32 may be off as shown in FIG.
When 2 is set to the telephone side, the changeover switch 31 is also controlled to be connected to the telephone side. Also, the changeover switch 3
Reference numeral 1 has a contact 31a on the telephone side and a contact 31b on the radio side. By using the microcomputer 7a in the control unit 7 to control all of them, various automatic controls and the like are performed, and at the same time, various settings can be made so that the user can easily use them. In addition, the changeover switches 31 and 32 are electronic type automatically controlled by the microcomputer 7a for confirming the presence or absence of reception and position registration as a telephone, and the telephone section is intermittently used while using the radio (state of FIG. 1). Only the presence or absence of reception is detected by the output signal of the detection unit 4 from the microcomputer 7a.
When it is received, the radio switches are turned off and the telephone is used by automatically connecting the changeover switches 31 and 32 to the telephone. With this configuration, even when using the radio,
You can immediately know when the phone is in reception, and you can turn off the radio and use the phone. This operation will be described below with reference to the flowchart of FIG.

In FIG. 2, (1) to (10) indicate respective steps. First, switch it on (1) and artificially select either the phone or the radio (2). If the radio is selected here, the radio is continuously controlled (3), and in this state it is checked whether or not the telephone is receiving.
(Four). If there is no reception to the telephone, the radio control continues as it is. On the other hand, when the telephone is selected in step (2), the telephone is in the reception standby state, and it is checked whether or not the reception is present (5). If there is no reception, the reception standby state is continued. When there is a reception to the telephone, the changeover switches 31 and 32 are switched to the telephone side (6), and a reception sound is generated.
(7) The call is controlled (8), and when the call ends, the next mode is selected (10). Also, if the telephone is in the receiving state in step (2), call / call control is performed.
Go to (9) and step (10).

Although the antennas 1 and 21 and the synthesizer portions 3 and 23 are separately provided in the above embodiment, they may be made common by devising.

[0011]

As described above, according to the present invention,
Since the mobile radio and mobile phone are integrated, it is possible to use the two media while maintaining portability.
It has a great effect in practical use.
