Abstract

PURPOSE:To control properly the transmission mode of additional information depending on the size of a recording paper and the size of an original by providing a means discriminating the size of the recording paper, deciding the size of an original to be sent and generating additional information such as sender information. CONSTITUTION:When sender information is selected in a control circuit 28 for applying control, a data is inputted from an operation section and the data is stored in a sender information storage circuit 18. When the transmission mode is selected, the type of recording paper of the opposite side (long recording paper or cut paper) is recognized. When the recording paper of the opposite side is cut paper, the sender information is overlapped on a part of region of the original and then sent. When the original of a transmitter side is a long original, the sender information is added before the original information and sent as to the original obtained by dividing the long original (or the 2nd and succeeding original). When the recording paper of the opposite side is long recording paper, the sender information is added before the original information and sent.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image communication device that transmits not only a document image but also additional information such as sender information and time.

[Conventional technology]

A facsimile device is known as one of this type of image communication device, but in a conventional facsimile device, sender information (information for identifying the sender) that is sent before sending a single message (V). The delivery mode was fixed. In other words, as a mode of transmitting source information that is transmitted before the image signal, ■ A mode of transmitting the source information immediately before the original information to be transmitted: (
The first part of the original to be transmitted and the transmission source information are superimposed and transmitted; either of the following was selected by test switch calculation.

[Problem I7!1 to be solved by the invention] However, in conventional facsimile machines, the recording paper size of the other party's facsimile machine is determined for each communication, and based on this, the transmission signal is sent before the single-picture signal. Because the method of sending the original information was not changed, the drawbacks described in Section F were observed.

First, we will discuss the case where the recording paper on the communication side is cart/cart paper of the same size as the original size on the transmitter side.

In this case, if the sender information is sent before sending out the image signal, there is a drawback that two sheets of recording paper (cut paper) are required due to the sender information. Further, unlike the above-mentioned transmission mode, if the sender information and the original information are transmitted in a superimposed manner, only one sheet of recording paper (cut paper) is required, but there is a drawback that the received image becomes difficult to see.

Next, a case will be described in which the recording paper on one communication partner side is a long recording paper with the same width as the original on the transmitter side.

In this case, even if the source information is transmitted just before the original information, the recording paper (cut paper)
There is no need for two copies. However, when the first part of the document and the source information are transmitted in a superimposed manner, the source information and the image information overlap, making it difficult to see the recorded image.

Therefore, an object of the present invention is to change and control the sending mode of various additional information such as sender information and sending time to a more appropriate one according to the recording paper size on the receiver side and the document size on the transmitter side. An object of the present invention is to provide an image communication device that achieves the following.

↓ [Step F to solve the problem] Unreleased 1! In IJ, there are means for identifying the size of recording paper attached to the other party's device to which image information is to be transmitted, and means for determining the size of the document to be transmitted.

and means for generating additional information such as sender information, and is configured to appropriately control the transmission mode of the additional information according to the size of the recording paper and the size of the original document.

〔Example〕

As shown in FIG. 1, an image communication device to which IJ1 is applied has a means C-1 for identifying the size of recording paper installed in the other party's device to which image information is to be transmitted, and a means for identifying the size of the recording paper to be transmitted. a means C-2 for determining the size of the source information, a means C-3 for generating additional information such as source information, and a mode of transmitting the additional information in ri77 according to the size of the recording paper and the size of the document. and a control means C-4 for appropriately controlling.

More specifically, the operation of this device will be explained as follows.

First, in a pre-procedure, the type of recording paper loaded on the receiver side is notified to the present apparatus.

It is now assumed that an A4-sized document is set in the apparatus as image information to be transmitted, and an A4-sized cut sheet is loaded as recording paper in the receiver. In this case, the sender information is superimposed on a partial area of the document and transmitted.

On the other hand, if the original to be sent is a long original and the recording paper on the receiver side is an A4-sized cut sheet, the original to be sent is divided into a plurality of parts and sent.

At this time, for images obtained by dividing a long original, sender information is added to the front of the original image and transmitted.

Furthermore, if a long recording paper is installed as the recording paper on the receiver side, sender information is added immediately before the original information and transmitted, regardless of the size of the transmitted original.

Add before transmission.

Furthermore, if the recording paper on the other side is a long recording paper, sender information is added to the front of the original information and transmitted.

FIG. 3 is a flowchart showing the control procedure to be executed by the control circuit 28 shown in FIG.

In Fig. 3, the telephone line is connected to the stay and bus S30.
Connect to the filling machine side. That is, a signal with a signal level r Q of 1 is output to the signal line 28a.

In step S32, it is determined whether the transmission mode is selected or not. If the transmission mode is selected, the process proceeds to step 538; on the other hand, if the transmission mode is not selected, the process proceeds to step S34.

In step 534, it is determined whether or not the source information storage mode is selected.0If the source information storage mode is selected, the process proceeds to step 536.On the other hand, if the source information storage mode is selected. If not, the process advances to step S32.

In step 536, storing source information;
That is, after outputting 1 source information to the signal line 18b,
A write pulse is generated on the signal line 28e.

In step 538, the telephone line is connected to the facsimile machine. That is, a signal of signal level "1" is output to the signal line 28a.

Step S40 represents the previous order. binary
Signal transmission is performed by controlling signals on the signal line 28f and the signal line 28g. Further, the binary signal is received by manually inputting the signal on the signal line 8a.

In step S42, it is determined whether the recording paper on the communication partner side is cut paper (that is, whether the signal on the signal line 8b has a signal level of "1"). When the recording paper on the phase "side" is cut paper (that is, when the signal 1ab is at the signal level "1"), the process advances to step S44; on the other hand, when the recording paper on the phase "to" side is not cut paper ( Namely.

It is a long recording paper, and the signal on the signal line 8b is at the signal level "
0), the process advances to step S54.

In step S44, the sender information is superimposed on a partial area of the document and transmitted. That is, after outputting a signal of signal level "1" to the signal line 128b, a reading start pulse is generated to the signal line 28c.

In step 346, it is determined whether the length of the transmitted information in the sub-scanning direction exceeds 297 mm. This is determined based on the number of transmission lines output to the signal line 20b and the transmission mode (standard/fine mode). The length of the transmitted information in the sub-scanning direction is 297
If it exceeds mm, the process advances to step S50. On the other hand, if the length in the sub-scanning direction in the transmitted information does not exceed 297 mm, the process advances to step 548.

In step 348, it is determined whether reading of the image information for one sheet has been completed (that is, whether a pulse has been generated on the signal line 20c). When the reading of the image information for one sheet is completed (that is, when a pulse is generated on the signal line 20c), the process advances to step 358. On the other hand, when the reading of the image information for one sheet has not been completed (that is, when the pulse is generated on the signal line 20c), the process proceeds to step 358. , when no pulse is generated on the t1 return line 0c), step 5
Proceed to step 46.

Step S50 represents a post-procedure. The binary signal is transmitted by controlling the signals on the signal line 28f and the signal line 28g. Further, reception of the binary signal is performed by inputting the signal on the signal line 8a.

In step S52, one source information is added to the front of the document and transmitted. That is, a signal of reliability level "0" is output to the signal line 28b.

In step S54, sender information is added to the front of the original and transmitted. That is, a signal of signal level "0" is output to the signal line 28b.

In step S56, it is determined whether or not the reading of one sheet of image information has been completed, that is, whether or not a pulse has been generated on the signal line 20c. When the reading of the image information for one sheet is completed (that is, when a pulse is generated on the signal line 20c)
, proceed to step 358.

Step S58 represents the subsequent order.

In step S60, it is determined whether or not the next document is set.If there is a zero-order document and there is one mode change, the process advances to step S40, and the other
If there is no mode change, proceed to step S42.
Further, if there is no next document, the process advances to step 362.

In step S62, the telephone line is connected to the telephone side. That is, the signal level "0" is applied to the signal line 28a.
Output a signal.

Step S64 represents an off state (line open state).

In the embodiments described above, if the recording paper on the receiver side is not cut paper (that is, if it is a long recording paper), sender information is added to the front of the document and transmitted.

On the other hand, if the recording paper on the receiver side is cut paper and the original size on the transmitter side and the recording paper size on the receiver side are approximately 100 yen, the sender information is superimposed on the original information ( In other words, the information was logically ORed) and transmitted. The reason for this is that if the sender information is added before the TX document and transmitted, two sheets of recording paper will be required on the receiver side. For this reason, the logical sum of the source information and the document information is transmitted, and the size of the image information sent from the transmitter side is made to be the same as the recording paper size on the receiving side.

However, other methods may be used to make the size of the image information to be transmitted the same as the size of the recording paper. For example, it is also possible to stop the transmission of the original image by the information j1'L corresponding to the source information. Additionally, the transmission of source information may be removed if desired.

Further, in the embodiments described above, A4 size recording paper was used, but it goes without saying that the present invention can be applied to other recording paper sizes as well.

〔Effect of the invention〕

By implementing the present invention, specifically, the following effects can be obtained.

If cut paper of the same size as the original on the sending side is loaded as recording paper on the receiving side, the sender information can be superimposed on a partial area of the original and transmitted, so the reproduced image will not be received. It does not protrude from one sheet of recording paper (cut paper) on the machine side, and as a result, the recording paper can be used effectively.

In addition, if the recording paper on the communication side is a long recording paper that has the same width as the original on the sending side, the sender information can be transmitted before the original information, so the beginning of the original can be transmitted. Even when there is image information in a part, the inconvenience that the source information and image information are confused is solved. As a result, it is possible to obtain the effect that the recorded image becomes easier to see.
