Description

The present invention relates to a facsimile machine.

[Prior Art] A facsimile apparatus will be described as an example of a conventional communication apparatus.

In conventional facsimile communication, the transmitter recognizes the document length by detecting the leading and trailing edges of the document using sensors and the like arranged in a reading unit and the like, and recognizes the document length, and transmits data for the document length. Was to be sent.

[Problems to be Solved by the Invention] However, in the above-described conventional example, for example, when a plurality of originals having different lengths are to be sent, except when the receiving side can adjust the length at the time of image reproduction with a memory receiver or the like. In this case, the length of the reproduced image varies. For this reason, when filing a received document, it is necessary to re-copy to a fixed length, or a stack failure occurs when an extremely short or long image is reproduced.

Also, since the other machine uses cut paper, etc., if a cut paper declaration has been made on the DIS, there is also a case where the transmitter side sends it in a fixed length, but in this case, for example, a short original Since the remaining space of the standard length is sent out white, the efficiency of the recording paper on the receiving side deteriorates,
There is a problem that transmission efficiency is reduced.

Therefore, by continuously transmitting image data of a plurality of pages as image data of one page in a communication procedure, communication efficiency can be improved.

However, in the case of facsimile communication, an operator on the transmission side requests a change in transmission resolution in accordance with the fineness of the characters of the original, or a mode change is required due to a change in size when originals of different sizes are mixed. . In order to perform a mode change, the facsimile recommendation specifies that a new transmission mode be notified from the transmission side.

On the other hand, in the case of continuously transmitting image data of a plurality of pages as image data of one page in a communication procedure according to the recording paper size of the receiving side or a preset size, communication of a procedure signal between pages is not performed. Since the mode change is not performed, the transmitting side cannot notify the receiving side of the mode change.
Then, when a mode change is required, if the image data is transmitted in the previous mode without notifying the new mode from the transmission side, the mode change must be performed according to the instruction of the user on the transmission side. Nevertheless, the mode was not changed ignoring the user's instruction, and the image data was changed to match the new mode. It is conceivable that the image is transmitted continuously and the image intended on the transmitting side cannot be restored on the receiving side.

In view of the above, the present invention provides an apparatus capable of improving communication efficiency and transmitting a mode change correctly by continuously transmitting image data of a plurality of pages as image data of one page in a communication procedure. Aim.

Means for Solving the Problems The present invention resides in a facsimile apparatus for transmitting image data in a facsimile apparatus capable of continuously transmitting image data of a plurality of pages as image data of one page in a communication procedure. Detecting means for detecting whether or not a mode change is performed between pages; and, if the mode change is not performed between the pages, according to the detection result of the detecting means, the image data of a plurality of pages is transmitted to the transmitting procedure. If the image data before and after the mode change is to be transmitted continuously as the image data of the upper one page, and the mode is changed between the pages, the image data before and after the mode change is transmitted in the communication procedure in the first step.
And control means for preventing the image data of the page from being continuously transmitted.

Embodiment FIG. 1 is a block diagram showing a schematic configuration of a facsimile apparatus according to an embodiment of the present invention.

The display unit 1 displays various types of information such as the status of the apparatus, the caller, the telephone number, and time information.

The reading unit 4 is composed of a CCD or the like and reads a document, and the recording unit 6 records an image of an image signal on recording paper.

The control unit 5 is configured by a microprocessor element or the like,
It controls the entire apparatus, and executes control operations according to a control program stored in the ROM 2. ROM2
Stores a program for controlling the control unit 5. The RAM 3 stores data that can be set by an operator, such as whether or not the original length can be selected.

The communication unit 7 modulates and demodulates image signals during facsimile communication.
It controls the automatic dialing (automatic calling) to the communication line 9 and the like. The communication unit 7 is configured by a modem, a network control device, and the like.

The operation unit 8 is used for operating the apparatus and inputting various information, and includes a plurality of key input switches, a key input switch scanning circuit, and the like.

FIG. 2 is a flowchart illustrating a transmission operation based on the above configuration.

First, at the time of transmission, the control unit 5 determines whether or not to control the document length to a fixed form (S1).
Normal document transmission (S2) is performed. This selection can be set by the operator using the operation unit or the like.

Next, when performing the standard transmission control of the original, it is determined whether the original length is determined by ISO or adjusted to a special size desired by the operator (S3).

When the original is adjusted to a special size, in the present embodiment, the original length is adjusted to the original length of the first page. First, an original of one page is transmitted (S4), and the original length is stored in the RAM 3 by a method such as counting the number of lines.

If there is no next manuscript (S5), go to the next step.
The image transmission ends.

If there is a next original in S5, the original is stored in RAM3
While comparing with the original length of the first page stored in (S
7) Send image data (S6).

In S7, if the original reaches the original length of the first page, the transmitter sends out an MPS (Multi Page Signal) to divide the page (S13), and continues the image transmission again from S6 with the rest as the next page. I do.

If the page ends on a stair less than the length of one page (S8), it is determined whether the next document is packed in the remaining document space and sent, together with the presence or absence of the next page (S9).

If there is no next page, the remaining document length is white-filled (S12), and the transmission is terminated in a post procedure.

If the original is not packed and sent even if there is a next page, the remaining original length is packed with white (S14), and the original transmission is continued.

In the case of setting the document to be packed and transmitted in S9, it is checked whether or not there is a mode change (S10). If there is a mode change, the document is not packed.

If there is no mode change, the transmission of the next original is continued (S15).

The time required to start reading the next original can be, for example, a method of transmitting a FILL and providing a receiver, as described in the CCITT T4 recommendation.

 The above control is repeated until the transmission original is completed.

Further, in S3, the adjustment to the document length specified by ISO can be realized by changing the specified length referred to in S17 from the length of the first page of the previous example to the ISO standard length.

That is, first, image data is transmitted (S1
6) When the ISO standard length is reached, divide the page in a later procedure (S1
3) The remaining page is the next page, and the image transmission is continued again from S16.

If the page ends at a stage where the length does not reach the ISO standard length (S18), it is determined whether or not the next original is packed in the remaining original space and transmitted, together with the presence or absence of the next page (S1).
(9, S20) If there is no next page, the remaining document length is white-filled (S12), and the transmission is terminated toward the post procedure.

If the original is not packed and sent even if there is a next page, or if the remaining original length is not packed and sent, the remaining original length is packed with white (S23) and the original transmission is continued. .

In the case where the setting is such that the original is packed and transmitted in S20, the presence or absence of a mode change is subsequently checked (S21).

If there is no mode change, transmission of the next original is continued (S24).

As described above, in the present embodiment, when transmitting a facsimile image, a procedure is provided in which an operator can select a document length to be adjusted.When transmitting a fixed length, when a document having a plurality of leaves less than the fixed length is used, a fixed size is set. By making it possible to select to pack data for a long time, it is possible to improve the communication efficiency as well as the efficiency of the other party's recording paper.

In the above embodiment, the selection of the original length is set by the transmitting side operator. However, the transmitter side declares the expected original length by, for example, a non-standard signal (NSF) from the receiver side. The same effect can be obtained by sending the document according to the document length.

According to the first and second aspects of the present invention, it is detected whether or not a mode change in a facsimile recommendation is performed between pages.
If the mode change is not performed between the pages according to the detection result, the image data of a plurality of pages is transmitted in one communication procedure.
In the case where the image data of the page is continuously transmitted and the mode is changed between pages, the image data before and after the mode change is not continuously transmitted as the image data of one page in the communication procedure. When the mode change must be performed according to the instruction of the user, the mode is not changed by ignoring the user's instruction, or the image has changed the mode, but without notifying the receiving end of the mode change, one page in the communication procedure. The image data is transmitted continuously as the image data, and a problem that the image intended on the transmitting side cannot be restored on the receiving side can be prevented.
