When a call is received from the other party, that is, a voice signal is received, the signal is received by an antenna 30, and the received signal is input to an RF (radio frequency) receiving section 32 by a duplexer 31. The detected signal is sent to the first signal processing section 33. Among the outputs of the first signal processing section 33, the control signal is sent to the control section 50 to perform predetermined overall control, and the audio signal passes through the first amplification section 34 and drives the speaker 6 as a receiving sound. do.

Regarding the control system for the received signal, a control signal is applied from the first signal processing section 33 to the control section 50, and this control signal is subjected to predetermined processing and then sent to the ton generator 51.
is added, and a ringer sound is emitted from the ringer speaker 9. The control unit 50 also sends control signals back and forth to the telephone key matrix 52, and the send key in the telephone keypad unit 7 (reference numeral 7 is shown in FIGS. 1 and 2) connected to the telephone key matrix 52 By pressing
A predetermined protocol is performed with the base station, a connection is established, and a conversation is established. The call state is ended by pressing the end key on the same telephone keypad section 7.

Next, when making a call to the other party, that is, transmitting an audio signal (sending a call), the acoustic signal entering the microphone 8 is converted into an electrical signal, passed through the second amplifying section 35, and transmitted to the second amplifying section 35.
After performing predetermined processing in the signal processing unit 36 of the
Added to 0 and sent. telephone key matrix 52
By pressing the desired number with the numeric keys of the telephone keypad section 7 connected to the telephone keypad section 7, and then pressing the send key of the same telephone keypad section 7, the control section 50 is operated through the telephone key matrix 52, and the above-mentioned RF transmitter 37
is transmitted and the call state is established. The call state is ended by pressing the end key on the same telephone keypad section 7.

The audio system, ie, the transmission and reception of audio signals, has been described above. Next, the facsimile function, ie, fax transmission and reception, will be explained. When sending a fax, there are automatic sending and manual sending, and when receiving a fax, there are automatic receiving and manual receiving. The fax automatic manual transmission/reception switch button 3 (numeral 3 is shown in FIGS. 1 and 2) is
This is a switch button for switching between fax automatic/manual transmission and fax automatic/manual reception modes, and sends control signals back and forth to the fax key matrix 53.

[0017] In the case of automatic/manual fax transmission, first,
When reading a document, by pressing the read button in the fax key matrix 53, the control unit 50
from the reading unit 60 (contact image sensor 22 in FIG.
), a predetermined operation is performed under the control of the reading control unit 61, and by tracing the document, the rotary encoder 62 rotates. The signal generated from the rotary encoder 62 enters the waveform control section 63, and is calculated from the controlled signal and the signal read from the reading section 60 based on the pulse/rotation of the rotary encoder 62 and the radius of the roller 19 in FIG. The reading control unit 61 converts the image into an actual image signal. After being converted into an actual image signal by the reading control unit 61, the data (image signal) is compressed by the data compression unit 64, passed through the third signal processing unit 65, and then stored in the image signal storage unit 6.
6, and the image signal is stored.

Automatic transmission of stored image signals,
Switch the fax automatic manual transmission/reception switch button 3 of the fax key matrix 53 to automatic transmission mode, dial the other party, that is, press the desired number with the number keys of the telephone keypad part 7 connected to the telephone key matrix 52, Next, by pressing the send key on the same telephone keypad section 7, after receiving the call, the image signal storage means 6
The image signal stored in the fax modem 67 is read out, subjected to predetermined processing by the third signal processing section 65, and sent to the fax modem 67.
through the second signal processing section 36, and then from the duplexer 31 to the antenna 3 via the RF transmitting section 37.
Sent through 0. After the transmission is completed, the transmission will automatically end. That is, in the case of automatic fax transmission, after switching the fax automatic manual transmission/reception switch button 3 to automatic transmission mode, dialing, and pressing the send button, the fax is sent to the other party according to the fax communication protocol determined by CCITT, etc. Automatically transmits image signals and disconnects the line after transmission.

Next, manual fax transmission becomes possible by switching the fax automatic/manual transmission/reception switching button 3 of the fax key matrix 53 to manual transmission mode. Manual transmission of a fax is to switch to a predetermined fax transmission protocol and transmit a fax by pressing the fax manual transmission button in the fax key matrix 53 after once switching to an audio signal.

Before explaining the automatic/manual reception of faxes, the display means 2 (designated with reference numeral 2 in FIGS. 1 and 2) will be explained. The display means 2 is used to confirm in advance whether to make a hard copy of the content before sending it or after receiving it. By checking the content before sending it, you can correct any mistakes. To check the contents in advance,
A predetermined desired image signal is selected and read out from the image signal storage section 66 by the image call key in the fax key matrix 53, and after being subjected to signal processing in the fourth signal processing section 68, it is added to the data decompression section 69, There, the image signal is decompressed and applied to the image processing section 70, and after a predetermined function is added, it is displayed on the display means 2 through the screen control section 71, so that the contents can be checked.

When displaying an image signal on the display means 2, the screen control button 4 shown in FIGS. 1 and 2 is used to
The image is displayed by operating the image control key matrix 54, and this control has functions such as scrolling, enlarging, and reducing. In addition, the image control key matrix 54
can selectively erase part of the image signal. Therefore, there is no need to transmit or hard copy all the image signals stored in the image storage means 66, and it is possible to selectively transmit or hard copy them. That is, after confirmation on the display means 2, it is possible to send the displayed image signal as is by pressing the fax manual transmission button in the fax key matrix 53, but the image signal must be displayed and confirmed on the display means 2. There is no need to send it after that, and you can send it without checking it, or you can check it and make any necessary corrections before sending it.

Next, automatic/manual reception of faxes will be explained. Regarding automatic fax reception, first, the fax automatic manual transmission/reception switching button 3 of the fax key matrix 53 is used to switch to the fax automatic reception mode. In this case, the RF receiving section 32, etc., and the RF transmitting section 37, etc. are in a so-called idle state. When a call is received from the other party, the call is automatically received, a facsimile from the other party is received, and this signal is input from the first signal processing section 33 to the fax modem 67 according to a predetermined fax reception protocol. If this signal is a predetermined signal, the control section 50 sends the predetermined signal from the fax modem 67 to the fourth signal processing section 68 and the image signal storage section 66, and the sent image signal is stored in the image signal storage section. The information is stored in the means 66. Manual fax reception is possible by switching the fax automatic manual transmission/reception switching button 3 of the fax key matrix 53 to manual reception mode. Manual fax reception means to switch to the voice system, make a call, and then press the fax manual reception button in the fax key matrix 53 to switch to a predetermined fax reception protocol and receive a fax image signal from the other party. It is something.

The image signal received manually/automatically by fax can be displayed on the display means 2.
The operation is the same as the display on the display means 2 described above, so the explanation will be omitted. Since the image signal automatically/manually received by facsimile is stored in the image signal storage means 66, it is also possible to transmit the received image signal as is to another facsimile.

When printing a hard copy using the printer unit 72 (in FIG. 3, the thermal head as the printer unit is indicated by reference numeral 26), the fax key matrix 53
By pressing the print button inside, the specified operation is performed, and by tracing it on the thermal paper, the timing pulse is sent through the rotary encoder 62 and the waveform control section 63, and the pulse width of the pulse/rotation is set in the opposite direction from when reading. This is converted into an actual size calculated from the rotation of the roller 19, and the signal width of the thermal head 26 of the printer section 72 is changed. Thereby, even if the rotation of the rotary encoder 62 is not constant, the writing result is constant. This also makes it possible to realize a hard copy function. Note that 73 is a printer control section.

FIG. 5 is a schematic diagram showing a state in which the mobile telephone with facsimile according to the present invention and a conventional facsimile are connected by radio waves. In FIG. 5, 12 is a handset, 13 is a main body, and 14 is a curl cord, which is the separated type described in FIG. 2. Reference numeral 28 indicates a document, and reference numeral 29 indicates a conventional facsimile.
