[0025]
First, a case where the digital cellular phone device 1 and the hand scanner 2 are not connected, that is, a case where a call is made will be described.
[0026]
For example, when making a call, the user performs a call operation using the operation input unit 14. For example, the control unit 20 controls the operation display unit 13 so that a screen based on the call operation is displayed, and a call signal is transmitted to the other party specified by the operation input unit 14 via the antenna 15. The wireless transmission / reception unit 17 is controlled as described above. As a result, a call state is established with the other party specified by the operation input unit 14.
[0027]
As described above, the voice input to the transmitter 121 is supplied to the voice encoding unit 19 when the telephone conversation state is established. At this time, the control unit 20 supplies control signals corresponding to the communication system to the speech encoding unit 19, the modem 18, and the wireless transmission / reception unit 17. The voice encoding unit 19 converts the voice from the transmitter 121 into digital data based on the control signal from the control unit 20 and supplies the digital data to the modem 18. The modem 18 generates a modem signal for voice communication from the digital data obtained by the voice encoding unit 19 based on the control signal from the control unit 20 and supplies the modem signal to the wireless transmission / reception unit 17.

The modem 18 demodulates the reception signal supplied from the wireless transmission / reception unit 17 and supplies the demodulated signal to the speech encoding unit 19. The voice encoding unit 19 decodes the received signal supplied from the modem 18 and outputs it as voice through the receiver 122.
[0029]
Here, at the time of audio signal transmission as described above, the modem signal obtained by the modem 18 corresponds to a communication system. For example, in a digital cellular phone device, a t / 4 shift QPSK signal of 42 kbps, a personal handyphone system ( PHS) is a 384 kbps t / 4 shift QPSK signal. On the other hand, the modem signals used when transmitting non-audio signals such as image signals are different, and when performing facsimile communication, for example, in a communication protocol, a 300 bps modem signal is transmitted by a low-speed modem. In image information transmission, an 8-level PSK signal (CITT V.27ter) of 4800 (2400) bps or a 16-level QAM signal (CITT of 9600 (7200, 4800) bps) is transmitted by a high-speed modem.
V. 29ter) must be generated.

[0035]
On the other hand, the image information processing unit 26 performs binarization and encoding processing on the information read by the reading unit 24 to generate an image signal, and the generated image signal is transmitted to the connection unit 22 and the connection unit 16. To the modem 18 of the digital cellular phone 1.
[0036]
At this time, the control unit 20 of the digital cellular phone device 1 controls the modem 18 and the wireless transmission / reception unit 17 based on the timing signal from the control unit 27 of the hand scanner 2.
[0037]
The modem 18 receives the image signal from the image information processing unit 26 in synchronization with the rotation of the roller 23 of the hand scanner 2 under the control of the control unit 20, and generates a modem signal corresponding to the facsimile communication system from the acquired image signal. To do. The modem 18 supplies the generated modem signal for facsimile communication to the wireless transmission / reception unit 17.
[0038]
Based on the control signal from the control unit 20, the wireless transmission / reception unit 17 converts the modem signal for facsimile communication from the modem 18 into a signal having a frequency corresponding to the transmission frequency and transmits it as a facsimile signal via the antenna 15. To do.
[0039]
As described above, in this embodiment, when the hand scanner 2 is connected to the digital mobile phone device 1 that can be used as a general digital mobile phone device, the digital mobile phone device 1 For example, the user can easily transmit a necessary part of a book to a home or the like in a library or the like by generating a facsimile signal from the information on the document 3 read in 2 and wirelessly transmitting it to the other party. Can do. In offices and the like, the user can easily perform facsimile transmission while staying on the seat. That is, since it is excellent in portability and the use range is not limited, facsimile transmission can be easily performed anytime and anywhere.
[0040]
Further, the hand scanner 2 does not have a function for generating a modem signal for facsimile communication, and generates a modem signal for voice communication in the modem 18 of the digital cellular phone device 1 and also transmits a modem signal for facsimile communication. By providing the function to be generated, the modem circuits can be integrated into one, so that the size can be reduced and the total cost of the digital cellular phone device 1 and the hand scanner 2 can be reduced.
[0041]
Moreover, the error rate between the digital mobile phone device 1 and the hand scanner 2 can be improved by digitizing the network control signal and the image signal transmitted from the hand scanner 2 to the digital phone device 1 as digital signals.
[0042]
Furthermore, since the digital mobile phone device 1 and the hand scanner 2 can be connected by a connector or the like, a facsimile function can be easily added without impairing the portability of the digital mobile phone device 1.
[0043]
In the above-described embodiment, the digital mobile phone device 1 and the hand scanner 2 are integrated by the connecting portion 16 and the connecting portion 22 such as a connector. However, the connecting portion 16 and the connecting portion 22 are used as cords with plugs. The digital cellular phone device 1 and the hand scanner 2 may be connected.
[0044]
Further, when reading the information on the document 3 by the hand scanner 2, the paper is fed by rotating the roller 23 by a motor (not shown). However, the paper is fed manually without providing the motor. Also good.
[0045]
Further, the digital cellular phone device 1 can be applied to a digital cordless phone device of a domestic personal handyphone system (PHS). In this case, the digital cordless telephone apparatus wirelessly transmits the image signal obtained by the hand scanner 2 to the parent device and transmits the image signal from the parent device via the telephone line.
