Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a facsimile machine, and more particularly to a facsimile machine that records information sent directly from a telephone.

(Prior Art) Generally, when a facsimile machine sends a document, it scans a document with a scanner to read image information, converts it into an electrical signal, and stores it in a buffer memory. The image information once stored in the buffer memory 4 is reduced in data amount (data compression) without losing the original information in the data compression/reproduction section, and then sent to the modem via the transmission control section and modulated. . The image information modulated by the modem is sent to the line via the network control section.

On the other hand, during reception, modulation number 18 (picture information) input from the line is guided to the modem via the network control unit, demodulated, and then
The data is sent to the data compression/reproduction unit via the transmission control unit. The data compression/reproduction unit reproduces the original information and stores it in a buffer memory. The image information stored in the buffer memory is sent to a plotter and recorded on recording paper.

Therefore, facsimile machines can quickly transmit image information to remote locations using telephone lines, and the spread of facsimile machines has been remarkable due to the immediacy of this information transmission and the reduction in size and cost due to technological advances. This applies not only within companies but also to ordinary households.

The widespread use of facsimile devices has required diversification of the functions of facsimile devices, and in particular, as a method for inputting and transmitting information, it is no longer possible to simply read image information written on a document with a scanner, as in the past. However, it also requires the transmission of information from terminals other than facsimile machines.

(Problems to be solved by the invention) However, regarding such conventional facsimile devices, CCITT (International Telegraph and Telephone Consultative Committee: Th

and Te1ephone Con5ultati
Since it is configured to receive only signals that have been compressed and modulated in accordance with the ``Ve Comm1ttee'' standard or a manufacturer's proprietary method, it is not possible to receive and record signals in other signal formats. Therefore, it was not possible to input information directly from the telephone to the facsimile machine and record it.

(Object of the Invention) Therefore, the present invention makes it possible to input information directly from the button phone to a facsimile machine by adding certain information to a combination of tone signals from the phone and detecting the tone signal. The purpose is to expand the functions of facsimile machines and improve convenience.

(Structure of the Invention) In order to achieve the above object, the present invention provides a facsimile device that modulates and transmits image information read by a scanner, demodulates the transmitted modulated signal, and records it on recording paper with a plotter. The apparatus further comprises a tone signal detection means for detecting a tone signal from an external terminal other than the apparatus, a decoding means for decoding the tone signal, and an information conversion means for converting the decoded information into information recordable by the plotter. This is a characteristic feature.

Hereinafter, the present invention will be specifically explained based on examples.

1 to 7 are diagrams showing one embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a facsimile machine, and the facsimile machine 1 includes a main body 2, a document table 3 provided above the main body 2 and on which a document is placed, an operating section 4, and a handset 5. The operation section 4 includes a numeric keypad 4a, operation keys 4b for inputting other commands, and a display section 40 for displaying input commands and information transmitted from the facsimile machine 1 to the operator. As shown in FIG.
, a network control section 16, a tone detector 17, a decoder 18, a system control section 19, the operation section 4, and the like.

The scanner 11 scans a document and converts it into an electrical signal, and the plotter 12 records image information sent from an external line and image information read by the scanner 11 on recording paper. The data compression/reproduction unit 13 compresses the image information read by the scanner 11 using the MR method or the MR method, and also converts the compressed information sent from the external line into original information. The modem 15 modulates the image information compressed by the data compression/reproduction section 13 into a signal form that can be transmitted over a telephone line, and also demodulates the signal sent from an external line. The network control unit 16 decodes the control signal and performs call settings, line establishment, etc.

The tone detector 17 receives a tone signal sent from the line,
In particular, MF)-n (Multi Freq'uency
Tone) and sends the detection result to the decoder 1B. This MF tone is a signal generated by pressing the button on a button phone, and generally,
Aiming to improve the transfer speed and stability when calling stations, we have created 6 frequencies in the band exclusively for selection signals, and by combining 2 of these frequencies, we can express 1 decimal number and 5 types of special codes, and it is possible to transfer signals within 1 second. Transfer of about 10 digits is possible.

The decoder 18 includes a memory that stores information using the tone signal as a parameter, and converts the tone signal into information based on the detection result of the tone detector 17. For example, the third
As shown in the figure, character information and numerical information are set by a combination of two types of tone signals and stored in the memory in the decoder 18, and the decoder 18 reads out the corresponding information from the detection results of the tone detector 17.

Output to.

Note that FIG. 3 shows an example of the correspondence between tone signals and information, and does not use all combinations. Furthermore, the correspondence relationship between tone signals and information is not limited to this. Furthermore, a fixed phrase may be displayed in combination with an asterisk button (*) or a pound button (#). In addition, in FIG. 3, SP indicates a space.

The system control unit 19 controls the operation unit 4, which is an interface unit with the operator, the data compression/reproduction unit 13, the buffer memory 14, the modem 15, the network control unit 16, the decoder 18, etc., and performs the sequence as a facsimile machine. Execute.

Next, the effect will be explained.

At the time of transmission, the facsimile machine 1 scans a document with a scanner 11 to read the image information, converts it into an electrical signal, and stores it in a buffer memory in the same way as a normal facsimile machine.
Store in 4. The image information once stored in the buffer memory 14 is compressed in the data compression/reproduction unit 13 to remove redundancy of the original, and then subjected to image conversion processing such as scaling conversion and linear density conversion, and then sent to the modem. 15 and is modulated. The image information modulated by the modem 15 is sent to the network control unit 1.
6 to the line.

On the other hand, reception differs depending on whether the transmitting station is a facsimile machine or a telephone, and will be explained separately for cases where the other party is a facsimile machine and a telephone.

First, when the other party is a facsimile machine, transmission and reception are performed according to normal facsimile transmission procedures, as shown in FIG.

That is, in response to ringing from the calling station, the facsimile machine 1, which is the called station, transmits a called station identification signal (CED) and a digital identification signal (DIS). The calling side receives this DIS and sends a digital command signal (DOS
) and a training check signal (TCP). The facsimile machine 1 on the called side receives the reception preparation confirmation signal (
CFR) to notify that reception preparations are complete. Upon receiving this CFH signal, the calling party sends information (ME
SSAGE) is transmitted, and when one page is transmitted and there is a next page, a multi-page signal (MPS) is transmitted. In response, the facsimile machine 1 on the called side sends a message confirmation signal (MCF), and the calling side, after a training check, sends the next page of information (MESSAGE).
) is output. When the next page runs out, the procedure end signal (
facsimile machine 1 on the called side sends an MC
After outputting F, the calling side outputs a disconnection command signal (DCN) to disconnect the line.

Next, when the other party is a telephone, signals are sent and received as shown in FIG.

That is, in response to ringing from the telephone that is the calling station, the facsimile machine 1 that is the called station responds to the CED as described above.
and the DIS signal.

An operator who wants to send information from a telephone should check the line connection and send, for example, a mensage mode signal (MM
D: MESSAGE MODE) is sent. This M
The MD signal is sent, for example, by pressing the asterisk button (*). When the facsimile machine 1 receives this MMD signal, it recognizes that the calling station is a telephone, connects the line to the tone detector 17 side, prepares to receive a message, and emits a READY signal (for example, a "beep"). ) is sent. After confirming this READY signal, the operator sends a message signal using the 12 keys (θ to 9 buttons, asterisk button, and pound button) of the button.

That is, as shown in FIG. 3, character information and numerical information are input by performing key operations corresponding to the information. In this case, as shown in FIG. 6, a fixed phrase may be stored in the decoder 18 in advance and input in the same manner as speed dialing on a telephone.

Alternatively, character information may be input in a pattern using the keys of the telephone. For example, the katakana shown in FIG. 7(a) is input as a pattern on the keys of a telephone as shown in FIG. 7(b). In this case, character information is sent by pressing the key in the hunting part in FIG. 7(b).

The message signal sent out in this manner is input to the scanner 11 as a tone signal and detected by the tone detector 17. The detection result of the tone detector 17 is sent to the decoder 18
The information is converted into information and recorded on recording paper by the plotter 12.

When the operator finishes sending the message signal, for example, the operator presses the pound button to send the message end signal (
ROM), and the facsimile machine 1 receives the ROM signal and sends out an ACCEPT signal (for example, a "pippy" sound). When the operator confirms the ACCEPT signal, he presses the pound button twice to send the disconnect command signal (DCN).
After sending the message, disconnect the line.

In this way, the functions of the facsimile device 1 can be expanded to send information directly from the telephone to the facsimile device 1, and the convenience of the facsimile device 1 can be further improved.

In the above embodiment, the decoded information converted by the decoder 18 is converted into recordable character information (dot information) by the plotter 12, but this conversion may be performed by a unique character generator or by a general A facsimile machine is provided to record the sender. Character generator fonts may also be used.

(Effects) According to the present invention, information can be input directly from a telephone to a facsimile device, and the functions of the facsimile device can be expanded to improve convenience.
