Abstract

PURPOSE:To unnecessitate the use of a complicated command/response when starting transmission and to shorten time for transmission by adding additional information before a picture data, transmitting/receiving the information, using a standard control signal, and transmitting the additional information of a transmitting telegraphic message similarly to picture information. CONSTITUTION:An additional data to be transmitted with transmitting information stored in an additional information storage part 1 is inputted as a signal 13, and a transmitting data switching part 3 adds a header showing the head and outputs the data to a communication control part 4 as a signal 34. The data switching part 3 outputs a picture data 23 from a picture data input part 2 to the communication control part 4 as the signal 34 continuously to the additional data. The signal 34 generated in this way is transmitted according to the communication control process of a facsimile by the communication control part 4. On the other hand, a signal 47 outputted by the communication control part 4 is outputted to an additional information display part 5 and a picture data output part 6 as an additional data 75 by a received data switching part 7. Thus, the control process is simplified when starting transmission and time until starting transmission is shortened.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile device, and more particularly to a facsimile device that transmits additional information along with a document when transmitting a document.

[Conventional technology]

Conventionally, this type of facsimile machine uses non-standard equipment signal (NSF) and non-standard equipment setting signal (NSS), which are procedure signals defined as CCITT options, to add additional information to the image information of the transmitted document. Sending and receiving.

[Problem to be solved by the invention]

The above-mentioned conventional facsimile machine sends and receives the additional information of the transmitted document using NSS and NSF in the communication control procedure, so when the amount of additional information is large, the transmission time of the procedure signal becomes longer. be. In addition, since it is necessary to determine whether the recipient's facsimile machine has the ability to receive additional information before sending, the control procedure for determining the ability of the recipient's device at the start of transmission becomes complicated, and this process also takes time. The disadvantage is that it takes a long time to start.

[Means to solve the problem]

The facsimile apparatus of the present invention includes: an additional information storage unit that stores additional information to be added to image information to be transmitted; a transmission data switching circuit that switches between the image information and the additional information and outputs the image information as transmission data; an image data input section for inputting information, a received data switching circuit for switching and outputting received image information and additional information from received data, an additional information display circuit for displaying the received additional information, and an additional information display circuit for displaying the received additional information; It has an image data output section that prints out image information, and a communication control section that adds additional information to the image information and transmits and receives the added information according to a facsimile communication procedure.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, and FIG. 2 is a format diagram of transmission data used in this embodiment.

In FIG. 1, the reading section, encoding section, decoding section, recording section, etc. of a normal facsimile machine are omitted.

The additional information section storage section 1 stores additional data that is transmitted in addition to the transmitted information. The image data input section 2 is an inter-finis circuit that inputs image data (transmission information) of a transmission document. The data switching section 3 is a data switching circuit that switches between additional data from the additional information storage section 1 and image data from the image data input section. The communication control unit 4 is a communication control circuit that executes facsimile communication control.

The additional information display unit 5 is a display circuit that displays additional data transmitted together with the image data. The image data output section 6 is an interfine circuit that outputs the transmitted image data to a facsimile recording section.

Next, a case in which additional data is transmitted and received together with image data will be described with reference to FIGS. 1, 2, and 3. Additional data to be transmitted together with the transmission information stored in the additional information storage section 1 is input as a signal 13. The data switching section 3 adds a header (2 bytes of SYN) indicating the beginning of the data to the signal 13, and sends it to the communication control section 3.
It is output as a signal 34. Further, the data switching section 3 outputs the image data 23 from the image data input section 2 to the communication control section 4 as a signal 34 following the additional data. Signal 3 generated in this way
4 is transmitted by the communication control unit 4 according to the facsimile communication control procedure. Next, the operation when the data created in the above procedure is received will be explained. The signal 47 output by the communication control unit 4 is switched to SYN by the data switching unit 7.
Two bytes are detected and output as additional data 75 to the additional information display section 5. Further, the image data is processed by detecting the EOL of the received data, and is outputted as a signal 76 to the image data output unit 6.

Figure 3 shows a facsimile communication control sequence diagram.
Communication is started using DIS and DCS, which are standard signals specified by the CCITT T30 procedure.

Furthermore, when the data generated by the facsimile device according to the present invention is received by a normal facsimile device, the EOL pattern is not included in the additional data portion, so the image data portion to which the EOL pattern is added is fraudulent. Since it is deleted as data, there is no problem in transmitting data like this one to a normal facsimile machine using standard control procedures.

〔Effect of the invention〕

As explained above, the present invention adds additional information to image data prior to transmission and reception, thereby making it possible to transmit additional information in a transmission message in the same way as image information using T2O standard control signals defined by CCITT. This has the effect that there is no need to use complicated commands/responses when starting transmission.

Furthermore, since the additional information can be transmitted at the same transmission speed as the image information, there is also the effect that the transmission time is short.
