Abstract

PURPOSE:To make the TTI(Transmitter Terminal Identification) information of a received picture easy to read by deciding the size of an original to be read and the size of the recording paper of a receiving side, and enlarging the size of the character picture of the TTI information to be added to the picture of the original in the case where the recording paper size is smaller than definite ratio to the original size. CONSTITUTION:The facsimile equipment of a transmitting of a transmitting side reads out the TTI information of character code information stored in a system control part 10, and converts it into picture information by a TTI picture generating part 3, and next, decides the original size according to the width of the original detected by a scanner 1, and besides, decides the recording paper size of the receiving side. Then in the case where the recording paper size is smaller than the definite ratio to the original size, the size of the character picture of the TTI information to be added to the original picture is enlarged. Thus, the character picture larger than definite size is recorded always in the receiving side, and the TTI information of the received picture becomes easy to read.

Description

[Detailed description of the invention] [Industrial application fields] The present invention relates to a facsimile device.

[Prior Art] When transmitting an image using a facsimile machine, the telephone number, station name, etc. that are registered in advance in the machine are added to the top of each page of the original image, and the information is recorded on the receiving side. TTI (TransmitterTerm)
The transmission function of ``inal identification'' is known.

1. Normal facsimile machines have the ability to send and receive original images of A4 size or larger, but last year, CCI
The TT recommends a small facsimile machine that sends and receives originals of A5 and A6 size as a notebook facsimile.

When such a small facsimile device receives a document image from a normal facsimile device, the received image is reduced to A5 or A6 size and recorded and output, depending on the recording size of the facsimile device. Therefore, the added 771 images are also reduced and recorded together with the original image.

For example, the line density of a typical 63 facsimile machine is 8 dots/l11 in the main scanning direction and 3.85 dots/l11 in the sub-scanning direction. On the other hand, when displaying alphanumeric and kana characters in a 771 image, a character font of about 16 dots horizontally and 9 dots vertically is often used. Therefore, the above font size is 211 in width! The height is about 2.
It becomes 34m5+.

[Problem to be Solved by the Invention] Now, for example, if an A4-sized document image is transmitted to an A6-sized small facsimile machine, on the receiving side, the font size is reduced to 172 in the vertical and horizontal dimensions. The above characters are extremely small, measuring 1 m+i in width and 1.17 mm in height.

In this way, conventionally, when the transmitted image is significantly reduced on the receiving side, such as when the sending side is A4 and the receiving side is A6, the text of the TTI image becomes smaller on the receiving side, making it difficult for the operator to read the TTI information. There was a problem that it became difficult to read.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a facsimile apparatus that solves the above problems and makes TTI information of received images always easy to read.

[Means for Solving the Problem] To this end, the present invention determines the original size to be read and the recording paper size on the receiving side when transmitting an image, and determines whether the recording paper size is smaller than a certain ratio to the original size. In this case, the size of a character image, which is TTI information added to a document image, is increased.

[Operation] If the transmitted image is significantly reduced on the receiving side, TTI
Since the text image of the information is enlarged and transmitted, the text image of a certain size or larger is always recorded on the receiving side, and the TTI information of the received image is always easy to read.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a block diagram of a facsimile machine according to an embodiment of the present invention. In the figure, a scanner 1 reads a document image and extracts image information, and in this embodiment, a document width sensor is provided to detect the width of a set document to be read. The plotter 2 records image information on recording paper.

The TTI image creation section 3 has a function of converting TTI information registered in advance into image information of a character image and enlarging the image as necessary.

The encoding/decoding unit 4 encodes the image information to be transmitted and decodes the received image information. The image memory 5 is used to temporarily store image information to be transmitted in the case of storage transmission.

The network control device 6 performs predetermined call origination and incoming call operations by acquiring a line, sending out a selection signal which is an originating optical telephone number, and detecting an incoming call.

The modem 7 modulates and demodulates image information and transmits the same, and also transmits various procedure signals in transmission control procedures.

The communication control section 8 controls the network control device 6 and the modem 7 to execute facsimile transmission according to a predetermined transmission control procedure.

The operation display section 9 displays operation guidance etc.
According to the guidance, various operations are performed to cause the facsimile machine to perform predetermined transmission/reception processing.

The system control section 10 is composed of a microcomputer system, and controls each section mentioned above to execute predetermined operations of the facsimile machine. In this embodiment, the system control unit 10 is provided with a RAM whose power source is backed up by a battery and which stores TTI information in the form of one-character code information.

The facsimile machine of this embodiment has the above configuration.

It is assumed that the telephone number, name, etc. of this facsimile station are registered in advance in the RAM in the system control unit 10 as TTI information.

When transmitting an image, the operator sets a transmission document on the scanner 1 and performs a predetermined startup operation.

This causes the facsimile machine to start the sending process,
As shown in Figure 2, a call is first made to the other party (process 10).
1). When the receiving party receives a call, it sends out a CHD signal and a DIS signal, as shown in FIG.

In response, the sending facsimile device sends out a DO8 signal, a modem training signal, and a TCP signal. The receiving side executes a predetermined modem training, and if the training is successful, sends out a CFR signal, and the sending side facsimile machine receives the CFR signal (as described above)
Process 102).

Here, the sending facsimile device has a system control unit 1.
0 reads out the TTIT information which is the character code information stored in
The TIT information is converted into image information for displaying an image in a dot pattern (processing 103). Next, the document size is determined based on the document width detected by the scanner 1 (process 104).
.

By the way, in the DIS signal in the transmission control procedure,
The CCITT recommendation stipulates that 40 bits of data be transmitted, and this data indicates the capabilities of the receiving facsimile machine.

Table 1 shows how to display the recording paper size, etc. using the above data. For example, the recording paper width is indicated by the 17th bit "
1", 84.18th bit is "1" in 256II+1
”, 297mm indicates A3, and in the case of the sort fax, the 33rd bit is set to “1”,
This indicates that the above 17.18 bits are invalid.

Then, at the 34th to 37th bits, the recording paper width is 151 ma.
The distinction between + A5 and 107 mm A6 and the resolution in the main scanning direction are shown.

The sending facsimile device determines the recording paper size of the receiving facsimile device based on the above data (process 10).
5), and the recording paper size on the receiving side is A3 compared to the original size on the sending side, as shown in Tables 2(a) to (c).
If the size ratio is about 1/2 or less, such as A5 or less for B4 or A5 or less for B4 (Y in process 106), each character image of the TTIT information is 2 times in the sub-scanning direction. Expand twice.

That is, the line density of this facsimile machine is 8 dots/sm in the main scanning direction and 3.85 dots/sm in the sub-scanning direction, and the font of each character in the TTIT information is as shown in Figure 4(a). , 16 dots horizontally and 9 dots vertically, the character size on the sending side is equivalent to 2m+++ horizontally and 2°34mm vertically. In the above process, such a character font is enlarged to 18 dots in the vertical direction (process 107), as shown in FIG.

On the other hand, the size ratio between the original size and the recording paper size.

If the set value is exceeded (N in process 106), the character image is not enlarged.

Next, start reading the original image (process 108)
. Then, the image information at the top of each page (processing 109
Y), after adding the image information of the TTI (processing 110
), encode and transmit (process 109). Further, image information that is not at the beginning (N in process 109) is encoded as is and transmitted (process 111).

Then, the above operation is repeated for each page of the transmission document (from N in process 112 to process 108), and when the final page has been processed (V in process 112), a predetermined post-message transmission control procedure is executed. (Process 113), the transmission process ends.

As a result, on the receiving side, the TTI image P is recorded at the beginning of the recorded image, as shown in FIG.

By the way, if the original size on the sending side is A4 and the original size on the receiving side is A6, the received image is recorded with the size ratio reduced to 1/2.

However, in this embodiment, as shown in FIG. 4(b), the characters are enlarged twice in the vertical direction and then transmitted on the transmitting side. Therefore, as shown in FIG. 4(c), the TT engineering image characters on the receiving side are reduced to 1 oboroma in the horizontal direction, but are recorded as 2.34+a+++ in the vertical direction, so the operator This makes it easier to read the TTIT information.

In addition, in the above embodiment, enlarging the TTI image is as follows.
This setting was made when the recording paper size is approximately 172 or less in size ratio to the original size to be sent, but it goes without saying that the size ratio can be set arbitrarily.
Although the image is enlarged twice in the sub-scanning direction, it may also be enlarged in the main-scanning direction, and furthermore, these magnifications can be set to arbitrary values, such as changing according to the above-mentioned size ratio. Of course.

[Effects of the Invention] As described above, according to the present invention, when transmitting one image, the document size to be read and the recording paper size on the receiving side are determined, and if the recording paper size is smaller than a certain ratio to the document size, In this method, the size of the character image, which is the TT information added to the original image, is increased and transmitted, so on the receiving side, the character image is always recorded over a certain size, and the TTI information of the received image is It becomes easier to read.
