Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device capable of transmitting and receiving images using a telephone line, and particularly to a device incorporated into a portable telephone.

[Prior Art and its Problems] Conventionally, a so-called facsimile is known as a device for transmitting and receiving images. With this facsimile, it is possible to accurately transmit information that is difficult to accurately transmit using language over the telephone or the like. However, such a facsimile is a stationary type and is difficult to carry.

Therefore, for example, if you want to immediately contact the person in charge at the head office about information you obtained on a business trip and which is difficult to convey accurately in the local language, you will have to go to a place where a facsimile machine is installed. There was a problem that information could not be transmitted quickly. The object of the present invention is to provide a mobile phone with a manual copying machine that solves the above problems.

[Summary of the Invention] In order to achieve the above object, the present invention provides an image input means for manually scanning a still image to produce an image signal, a storage means for storing the image signal, and a storage means for storing the image signal. a modulation means for generating a modulation signal obtained by modulating the audio frequency signal with the stored image signal at a speed faster than the scanning speed of the image input means; and a radio frequency for telephone line connection generated based on the modulation signal. a transmitting means for transmitting a signal; a receiving means for receiving a radio frequency signal from another portable telephone with a manual copying machine and converting it into the modulated signal; and a receiving means for demodulating the modulated signal to generate an image signal. The apparatus includes demodulating means for generating and storing the image signal in the storage means, and output means for reading out the demodulated image signal from the storage means or the image signal from the image input means and outputting it in a visible manner.

[Operation] According to the present invention, the still image scanned by the image input means is stored in the storage means in the form of an image signal. This image signal can be output visually by the output means, or it can be provided to the modulation means, which modulates the audio frequency signal into a modulated signal, and the transmitting means can be used to transmit the image signal to other manual copying machines. transmitted to the telephone. In other portable telephones with manual copying machines, this is received by the receiving means and converted into a modulated signal. This modulated signal is demodulated into an image signal by the demodulation means and stored in the storage means. The demodulated image signal stored in the storage means is outputted visually by the output means.

[Example] This example is based on the outer shell 2 of a mobile phone as shown in FIG.
A manual copying machine and a modulation/demodulation device are incorporated therein so that image signals from the copying machine can be transmitted and received by the transmitting section 4 and receiving section 6 of the portable telephone. As shown in FIG. 1, this portable telephone has a transmitting section 4
In addition to the receiving section 6, a transmitter 8, a receiver 10, a voice output section 12, a telephone communication circuit section 14, and a dial section 16 are observed.

When making a call using this portable telephone, switch the three-stage selector switch 18 provided in the call circuit section 14 during a call, operate the dial section l6, and input the telephone number of the other party. The dial signal is supplied from the circuit section 14 to the transmitter section 4 via the transmission selector switch 20, where a signal of an appropriate radio frequency is modulated by the dial signal and transmitted from the antenna 22. Note that the transmission selector switch 20 is switched to the communication circuit section 14 in the normal state. When the other party is called by this, an audio signal is generated by transmitting to the transmitter 10. On the other hand, a call from the other party is received by the antenna 22 as a radio frequency signal modulated with an audio signal, demodulated into an audio signal by the receiver 6, and then switched to receive. The signal is supplied to the receiver 10 and amplified through the switch 24, the telephone call circuit section l4, and the audio input/output section 12. Note that the reception selector switch 24 is also switched to the telephone call circuit section 14 side in the normal state.

This portable telephone has an image input section 26 at the bottom of the outer shell 2, as shown in FIG. ．． The image input unit 26 includes, for example, a photoelectric image scanner, an image sensor, and a light source, and scans the information paper 6 by moving the information paper 6 to be imaged onto the outer shell 2, as shown in FIG. Then, light from the light source is irradiated onto the information paper 6, and the light reflected from the information paper 6 is converted into an image signal by an image sensor. This image signal is input to a control section 30 composed of, for example, a microcomputer through an image signal input switch 28 and is stored in an image character memory 32. 34 is a speed detection section,
As shown in FIG. 2, a roller 34a is provided at the bottom of the outer shell 2, and the image input unit 2
6 scanning speed is detected and supplied to the control section 30. control f
The i30 determines whether or not this scanning speed is equal to or higher than the designated speed at which the information sheet 6 can be read by the image input section 26. If the scanning speed is equal to or higher than the designated speed, the i30 turns on the lamp 36 shown in FIGS. 1 and 2. Lights up to alert the user.

A print output section 38 is provided to transfer the information stored in the image character memory 32 in the form of an image signal onto another sheet of paper. This print output section 38 is also provided at the lower part of the outer shell 2, and the lower part of the outer shell 2 is placed on another paper 39 as shown in FIG. 3, and the output switch 40 shown in FIG. 1 is closed. When the outer shell 2 is moved at a speed lower than the set speed, the image signal from the image character memory 32 is supplied to the print output unit 38 and transferred onto another paper 39. In this case as well, when the outer shell 2 is moved at a speed higher than the set speed, the lamp 36 lights up.

Further, in order to transmit the information stored in the image signal form in the image character memory 32 to another portable image transmitter/receiver via a telephone line, a signal generator 42 and a modulator/demodulator 4 are provided.
4 is provided. The signal generating section 42 receives an image signal from the image character memory 32 via the control section 30 and modulates the image signal in a form suitable for modulation, for example, if the image signal is stored in a parallel format in the image character memory 32, Convert this to serial form. Then, the signal generating section 42 supplies the image signal converted into the serial form to the modulation/demodulation section 44 at a predetermined baud rate.

This baud rate is determined by the outer shell 2 when scanning an image in the image input section 26 and when transferring an image in the print output section 38.
is set faster than the movement speed of

The modulator/demodulator 44 modulates the audio frequency signal with the supplied serial image signal to produce a modulated signal.

This modulated signal passes through the transmission changeover switch 26 to the modulation/demodulation section 44.
By switching to the side, the signal is supplied to the transmitter 4, where it is converted into a radio frequency signal that can be connected to a telephone line, and is transmitted from the antenna 22.

Further, the antenna 22 receives a radio frequency signal from another mobile phone equipped with a manual copying machine supplied via a telephone line, and supplies this to the receiving section 6. The receiving section 6 converts this into an audio frequency signal, but the reception selector switch 24
If the modulation signal is switched to the modulation/demodulation section 44 side, the converted modulation signal is input to the modulation/demodulation section 44 . This input modulated signal is demodulated into a serial image signal and supplied to the signal generator 42. The signal generator 42 converts the serial image signal into a parallel image signal, and stores the parallel image signal in the image character memory 32 via the controller 30.

When actually transmitting the image signal stored in the image character memory 32, the three-stage selector switch 18 is switched during a call, and the earl section 16 is operated to call the transmission party and inform that the transmission will be carried out. As a result, on the receiving side, the reception selector switch 24 is switched to the modem/demodulator 44 side. On the other hand, on the transmitting side, the transmitting switch 2
0 to the modem/demodulator 44 side. As a result, the buzzer 46 sounds and the lamp 36 lights up, indicating that transmission has started. At the same time, the transmitter 4 starts transmitting. On the receiving side, when reception starts, the lamp 36 lights up to indicate that reception is being performed. When the transmission is completed, the lamp 36 on the transmitting side mobile phone turns off to indicate that the transmission has been completed. At this time, the transmission changeover switch 20 is automatically switched to the communication circuit section 14 side. In addition, in the mobile telephone on the receiving side, when the reception is completed, the lamp 36 is turned off to indicate that the reception has been completed. At this time, the reception changeover switch 24 is automatically switched to the communication circuit section 14 side. Although not shown in FIG. 1, automatic switching of the transmission changeover switch 20 and reception changeover switch 24 to the communication circuit section l4 side is performed by the control section 3.
It is done by 0.

In this way, the lamp 36 is turned on and off, and the transmission changeover switch 20 and the reception changeover switch 24 are automatically turned on and off.
In order to switch to the modem 4 side, the signal generating section 42 detects when the transmission changeover switch 20 is switched to the modulation/demodulation section 44 side (although this is not shown, the control section 30 detects this).

), a predetermined number of pulse signals, for example two pulse signals, are supplied to the modulation/demodulation section 44 and the control section 30 as transmission start instruction signals, and then, after a predetermined period of time, for example, one second, an image signal is supplied to the modulation/demodulation section 44.

Further, after a predetermined period of time, for example, 1 second, has elapsed since the transmission of the image signal is completed, a predetermined number of pulse signals, for example, two pulse signals, are supplied to the modulation/demodulation section 44 and the control section 30 as a transmission end instruction signal. The portable telephones on the transmitting side and the receiving side turn on the lamps 36 from the time when the transmission start instruction signal is generated until the transmission end instruction signal is generated. Further, in the transmitting side portable telephone, the control unit 30 or the buzzer 46 sounds when the transmission start instruction signal is generated. In addition, in the transmitting side mobile phone, when the transmission end instruction signal is generated or completed, the control unit 30 switches the transmission changeover switch 20 to the communication circuit unit 14 side, and in the receiving side mobile phone, the transmission When the generation of the termination instruction signal is finished, the control section 30 switches the reception changeover switch 24 to the communication circuit section 14 side.

When the receiver's mobile phone transfers the information stored in the image character memory 32 in the form of an image signal to paper, print output @1!3B is performed as described above.
is brought into contact with the paper, the output switch 40 is closed, and the outer shell 2 is moved on the paper at a speed lower than the set speed.
