Abstract

PURPOSE:To enable recording without generating a useless margin by discriminating difference between the size of an original and the size of a recording sheet on a reception side by a facsimile equipment on a transmission side and transmitting data in a form suitable for the size of the recording sheet on the reception side while executing the longitudinal/lateral conversion of the picture data when the sizes are different. CONSTITUTION:A longitudinal/lateral converting means for the picture data is composed of a picture storage part 18, extension circuit 19 and bit map 20. When the original on the transmission side is set throughout the longitudinal side of an A4 size (a short side is set in a main scanning direction and a long side is set in a sub scanning direction) and the width of the recording sheet on the reception side in the main scanning direction is same as the lateral width of an A3 size, such a state is discriminated on the transmission side and the picture data are transmitted while automatically converting the data from the lateral direction to the longitudinal direction. Accordingly, even when the longitudinal/lateral converting means for the picture data is not provided. in the facsimile equipment on the reception side, the contents of the original longitudinally set are reproduced on the recording sheet with the same form as a case that the original is laterally inserted. Thus, the margin is not generated in the recording sheet.

Description

[Detailed description of the invention] Dokuri Retired Emperor's Skin Separate The present invention relates to a facsimile machine.

In conventional communication between facsimile machines, if the width of the document is smaller than the width of the recording paper, it is recorded with some margin left in the width direction of the recording paper.

For example, as shown in FIG. 7, the width W of the document (2) on the sending side in the main scanning direction (A) is smaller than the width WIl of the recording paper (1) on the receiving side in the main scanning direction (A). If so, the recording paper (
There are margins (3a) at both ends of 1) in the main scanning direction (3
Recording is performed with b) remaining. However, such a recording method that produces blank spaces is not preferable from the viewpoint of economical consumption of the recording paper (1).

Therefore, when recording the image data of an A411 original on A3 recording paper by providing a storage means and an image data vertical/horizontal conversion means on the receiving side, the received image data is transferred through the storage means from horizontal to fir. A method for converting and recording data is proposed in JP-A-62-117468. According to this, as shown in Fig. 4, recording is performed with almost no margins on the recording paper (1), so there is no waste of recording paper.
Therefore, economical efficiency is improved.

However, since this conventional example always requires storage means and length/horizontal conversion means on the receiving side, facsimile machines without these means cannot enjoy the advantage of economical recording. Become.

In other words, it does not apply to many facsimile machines already in use.

The present invention has been devised in view of the above points, and is designed to economically consume recording paper during reception even in a facsimile machine that does not have a vertical/horizontal conversion means for image data. The purpose is to provide a facsimile machine with

The facsimile apparatus of the present invention, which achieves the above-mentioned object, includes a determining means for determining the difference between the recording paper size on the receiving side and the document size on the transmitting side, and a determining means for determining the difference between the recording paper size on the receiving side and the document size on the transmitting side, and in accordance with the determination result of the determining means. The apparatus includes a converting means for converting image data vertically and horizontally, and a transmitting means for transmitting the output of the converting means.

-■ If a facsimile machine with such a configuration is used as the sending side, even if the receiving facsimile machine does not have a storage means or a means for vertical/horizontal conversion of image data, the contents of a document to be read vertically can be read horizontally. The data will be reproduced on the recording paper in the same format as when it was sent, and there will be no blank space on the recording paper.

Disaster” L-retsu Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a block diagram of the facsimile apparatus of this embodiment, and LS (10) is a control section composed of a microcomputer. The control unit (10) includes an operation unit (11) having various operation keys, and a reading unit (11) that reads a document.
2), a recording section (13) that records image data, etc., a mechanical section (14) of the reading section and recording section, and a storage section (15) that stores various settings, image data, etc. A modem (16) that modulates and demodulates data, and an NCU that switches between telephone and facsimile and connects to a telephone line.
(17) is connected to exchange various data and perform control.

Figure 2 shows an image storage unit (18) consisting of a memory that stores compressed image data, an expansion unit (19) that expands the output of this image storage unit (18), and an expansion unit (19) that expands the output of the image storage unit (18), and sequentially and regularly stores the expanded data. This shows the relationship with the bitmap (20) to be stored in memory, and in normal cases, image data is stored in the bitmap (20).
) is output in the horizontal direction, but when the conversion control by the control unit (lO) is activated, it is output in the vertical direction (i.e. 3990001
,...1681,1. ...3990002.・・・
・21...3991680,...1680). The image storage section (1B), the decompression circuit (19)
) and the bitmap (20) constitute means for vertical/horizontal conversion of image data. Note that the expansion circuit (19) is connected to the control section (1
0), and the image storage section (18) and bitmap (20) can be provided within the storage section (15).

In this example, the document on the sending side is set with the short side of the A4 paper (lengthwise) in the main scanning direction and the long side in the sub-scanning direction), and the width of the recording paper on the receiving side in the main scanning direction is the same as the horizontal width of the A3 paper. In this case, the transmitting side determines this and automatically converts the image data from horizontal to vertical before transmitting the image. Explain with reference to.

In FIG. 3, first, in step (It), a document is set in the facsimile machine. Here, it is assumed that an A4 original is set so as to be passed vertically. Next, in step (112), the telephone number given from the operation unit (11) is input. Thereafter, the size of the document is detected in step (I3), and in the next step (I4), it is determined from this detection output whether the document is A4 size or not. In this case, since it is A4, it is determined Yes and the process proceeds to step (I5), but if it is not A4, the determination is NO and normal transmission is performed. Note that the flow of a normal transmission program is not shown. In step (15), the original data is stored in the image storage section (18) in a compressed form. Next, a call is made in step (+16), and after the call is made, the D sent from the receiving side is sent in step (I7).
is.

Receives NSF and C3I signals. The DXS signal includes information on the size of the recording paper on the receiving side (size in the main scanning direction - y).The NSF signal contains information on various functions on the receiving side, and the C8I signal contains the telephone number of the receiving side. .DI
The S signal is determined by the CCITT standard and is always sent, but the NSF and C3I signals are optional and are not necessarily sent, but if the NSF or C3I is sent, the recording paper on the receiving side is cut paper or
An identification signal indicating whether it is roll paper can be included.

Based on the received DIS signal, it is determined in step (#8) whether the recording paper is A3 or not. If the facsimile system also sends an identification signal indicating whether it is cut paper or roll paper, it is determined whether the paper is A3 roll paper or not. Here, if No, it will be sent normally, and if Yes, step (+19
) to send the DC3 signal. The DC3 signal is a signal that indicates in what mode data is to be sent, specifically A4
This includes information such as the original size such as 84 or 84, and the transmission speed. After transmitting this DC3 signal, the horizontal data is converted to vertical data (step 1110). This means sequentially outputting the data of the bitmap (20) in the vertical direction in FIG. This output data is then transmitted through the telephone line in step (1111).

Currently, the original is A4 size, but each time a sheet of original is sent, the receiving side must cut the roll paper, so information for this needs to be sent from the sending side.

Therefore, in step (1112) it is determined whether or not the manuscript is final, and if it is not final, it is determined in step (113) that the manuscript is
Send S signal. This MPS signal is a signal representing one sheet of original.

Next, in step (1114), the MCF signal (
Upon receiving the reception confirmation signal (receipt confirmation signal), data for the second document is transmitted in step (+111). Step (#12)
When the manuscript becomes final, that is, when all transmission is completed, EOP (final) signal and MCF (reception confirmation) are sent at steps (#15), (#16), and (#17), respectively.
signal, and a DCN (line disconnection) signal to end the flow. On the receiving side, the roll paper is cut every time the MPS signal or EOP signal is received.

In the above example, the original is A4 size and the recording paper is A3 size.
Although the description has been made regarding the case where the original size is 85 and the recording paper is 84 size, the same processing is performed. Further, although the case where the recording paper is roll paper has been described, the present invention is also applicable to the case where the recording paper is not roll paper but cut paper. In this case, the image is formed on half (1a) of the A3 or B4 paper as shown in Figure 6, and the remaining half (1b) becomes a blank space, but blank spaces remain on the left and right sides as shown in Figure 7. This is because there is an advantage in that the blank space can be used more effectively (for example, the blank space (1b) can be reused by cutting it in half).

In the above embodiment, the length Ls of the document in the vertical direction (sub-scanning direction)
(see Fig. 5) is equal to the horizontal direction (main scanning direction) dimension WR of the recording paper (see Fig. 4), but it is not necessarily necessary that =W□, and more generally is WS < W + t and equals.

It is sufficient if ≦WR. However, WS is the width of the document in the horizontal direction (main scanning direction).

As explained above, according to the present invention, the sender's facsimile machine determines the difference between the document size and the receiver's recording paper size, and if they are different, the image data is vertically and horizontally converted and sent to the receiver. Because the data is sent in a format that matches the recording paper size, the receiving facsimile machine does not have a special data conversion function (although it does have the effect of recording without unnecessary blank space). .
