Abstract

PURPOSE:To make it possible that the reception side confirms the communication mode by converting a communication mode information suitable for the function of an equipment on the reception side (the opposite of the communication), and transmitting said information prior to the image of an original. CONSTITUTION:The titled equipment is provided with a discrimination means A to discriminate the function of the reception-side equipment based on a procedure signal transmitted from said equipment, a decision means B to decide the communication mode in response to the output of the discrimination means A, and an output means C to convert the decided communication mode to an image information signal and output the result. On the transmission side, a signal transmitted from the reception side is identified, the mode-setting is executed; for instance, in case a reduction mode from an original in B4 size to that in A4 size is to be selected, an image information B4 A4 is generated and transmitted, and followingly, an original information is transmitted. As a result, necessary measure can be taken on the reception side preliminarily, and additional communication by the telephone after the communication can be prevented, or a repeated transmission due to the deterioration in the quality of an image can also be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an image communication device that transmits and receives an image information signal following the transmission and reception of a procedure.

[Prior Art] A facsimile device is widely known as one of this type of image communication device.

As a matter of course, conventional facsimile machines are capable of exchanging image information even if there is a difference between the functions of the sending device and the receiving device. For example, if the size of the document on the sending side is different from the size of the recording paper on the receiving side, reduction/enlargement is automatically performed, and if the scanning line density differs between the sending and receiving devices, the receiving side The scanning line density on the transmitting side is determined in accordance with the scanning line density of the transmitter.

Problem 1 to be Solved by the Invention However, since the communication mode is automatically determined, there is a drawback that the operator cannot know what mode has been selected.

As a result, depending on the type and content of the manuscript to be sent, it may be necessary to have another verbal meeting after the image information has been sent and received, or to send the manuscript again. It was said that

SUMMARY OF THE INVENTION In view of the above-mentioned points, an object of the present invention is to provide an image communication device configured to enable an operator on the receiving side to recognize the communication mode.

Means for Solving Problem E 1 In order to achieve the above object, in an image communication device that transmits and receives an image information signal following the transmission and reception of a procedure signal, a method is adopted to solve the problem based on the procedure signal sent from the receiving side device. A determining means for determining a function of a receiving device, a determining means for determining a communication mode in response to an output of the determining means, and an output means for converting the determined communication mode into an image information signal and transmitting the image information signal. Be equipped.

[Function] In the present invention, the function of the receiving side (communication partner) device is first determined, and communication mode information suitable for the function is converted into image information and transmitted prior to the original image. Due to this,
The operator on the receiving side can be informed of the transmission mode.

[Example] Hereinafter, the present invention will be explained in detail based on Examples.

In this embodiment, before transmitting the actual read image, the transmission mode information is converted into image information and transmitted as the image information. On the receiving side, it is possible to notify the operator of the transmission mode by simply reproducing the image on the recording paper without distinguishing between the actual read image and such transmission mode information (image).

Next, a process of converting transmission mode information into image information will be explained.

First, on the transmitting side, the N5F-C transmitted from the receiving side
5i-DiS signal and performs mode setting (5th
(see figure). At this time, for example, if it is necessary to select the reduction mode from B4 original to A4 recording paper, rB4→
The image information called A4J is converted into a character generator (RO
M 10 is stored in advance).

Image information must be transmitted line by line, so the above display rB4→A4J is changed to the transmission line density (3.85 lines/mff1 or 7.7 lines/mm).
) and create an image pattern for each line. That is, the transmission mode information is converted into image information and transmitted as if it were read data.

The transmission of such transmission mode information is as shown in FIGS. 3(A) to 3(C). First, when the control goes to the image signal transmission routine 514 (see FIG. 3(A)), the size of the original to be transmitted is detected (step 5l).
(10, see Figure 3 (C)),,For the sake of explanation,
It is assumed that the document size is B4 size.

Next, the DIS (Digital
11+fentjffcation Signal)
Based on the signal, the recording paper size (for example, A
4) is detected (step 5200). Examples of functions represented by this DIS signal include those shown in FIG. 11.

Then, on the transmitting side, the character information rB4→A smell is read out from the ROM 10 (see Figure 2) and stored in the RAM.
(step 5300) in which the data is temporarily stored in 8 and transmitted line by line. After all lines of information representing the character information are transmitted, the original manuscript information is subsequently transmitted (step 5400).

By doing so, information representing the transmission mode is recorded at the beginning of the received image. Therefore, if necessary, the operator on the receiving side can make a telephone reservation before receiving all the image signals, and then verbally check the image quality with the operator on the transmitting side after the reception is complete. When a telephone reservation is made from the receiving side, the device itself recognizes the operator's intervention and transmits the MPS after the image signal, as shown in Figure 9.
Send a PiP signal in response to the signal. Due to this,
The sending operator is called.

[Effects of the Invention] As described above, in the present invention, the communication mode information is converted into an image signal and notified to the receiving side, so the operator on the receiving side can take necessary measures in advance. As a result, repeat phone calls after communication,
This makes it possible to prevent retransmission due to deterioration in image quality.
