Abstract

PURPOSE:To avoid the reduction of a picture in an original by fetching the picture in the range of a right edge or a left edge designated with the original and executing the transmission or copy of the picture. CONSTITUTION:Signals corresponding to the position of the left edge or right edge in a designated original 1 are detected from a position detecting element 3 and a range detecting part 4 detects the left edge position and right edge position from these signals. A reading part 6 reads the picture signal of the range sandwiched by these left edge position and right edge position from the picture signals of the original 1 and the picture signal is transmitted or copied. Accordingly, when there is a margin, etc., in the edge of the original 1, the picture signal in the rage of these designated left and right edges is read by designating the left and right edges of the range where a significant character in the original 1 is printed. Then, the picture signal is transmitted or copied and it can be avoided to reduce the picture signal.

Description

[Detailed Description of the Invention] [Summary] Regarding a main scanning range specification method in a facsimile machine that detects a specified range in the main scanning direction of a document, an image within a specified range of the left and right edges of the document is captured and transmitted or copied at the time of transmission or copying. , with the purpose of avoiding reduction of the original image, is provided in correspondence with the main scanning direction of the original, and is placed at a specified position (
a position detecting element for detecting the left end position and the right end position), a range detecting section for detecting the left end position and the right end position from the signal detected by the position detecting element, and a position detecting element for detecting the left end position and right end position detected by the range detecting section. The configuration is such that an image signal read from a document can be captured and transmitted or copied within the range of the right end position.

[Industrial application field]

The present invention relates to a main scanning range designation method in a facsimile machine that detects a designated range in the main scanning direction of a document.

[Conventional technology]

In recent years, there has been an increase in the use of facsimile machines to transmit originals of sizes other than standard sizes (A3, B4, A4, etc.), such as printer paper for computers.

In such a case, the facsimile machine is A4 or B4
If the width of the destination facsimile machine is narrower than this, it will be reduced at the sender's end. I'm trying to send it.

[Problem to be solved by the invention]

Therefore, when the document is slightly larger than A4 width, the facsimile machine recognizes that the document width is 84 mm, and if the destination facsimile machine's recording paper width is A4, it will be the width of A4 from the B4 width. The image will be reduced in size (81% reduction) and sent, and the image will be reduced and printed in small size (printed) on the recipient's recording paper.

For this reason, for example, if you are trying to send a document printed on computer printer paper, there will be margins on the left and right edges, and even if the area where significant characters are printed is within the width of A4 paper. However, there is a problem in that the entire image is reduced in size and transmitted, making the printed image small and difficult to see on the receiving side.

An object of the present invention is to capture an image within a specified range of the left and right edges of a document, and to avoid reducing the image of the document when transmitting or copying.

[Means to solve problems]

Means for solving the problem will be explained with reference to FIG.

In FIG. 1, the position detection element 3 detects signals corresponding to designated left and right end positions in the document.

The range detecting section 4 detects the specified left end position and right end position from which an image signal is to be captured from within the document, based on the signal input from the position detecting element 3.

The reading unit 6 reads the image signal of the range sandwiched between the specified left end position and right end position from among the image signals of the original 1.

[Effect]

As shown in FIG. 1, the present invention detects signals corresponding to the specified positions of the left end and right end in the document 1 from the position detection element 3, and the range detection section 4 detects the left end position and right end position from these signals. The position is detected, and the reading unit 6 reads an image (No. 3) in the range sandwiched between the left end position and right end position from the image signal of the original 1, and transmits or copies it.

Therefore, if there is a margin at the edge of document 1, by specifying the left and right ends of the range in which significant characters are printed in document 1, the image signal of the specified left and right end ranges will be It is possible to avoid being read, transmitted or copied, and reduced.

〔Example〕

Next, the configuration and operation of one embodiment of the present invention will be explained in detail using FIGS. 1 to 5.

In FIG. 1, a CCD (charge coupled device) 2 reads an image of a document 1. As shown in FIG.

The position detection element 3 is an element that is provided in correspondence with the main scanning direction of the original 1 and detects a position corresponding to a specified position (left end position and right end position), and is an element for scanning in which LED elements are arranged in a line. It is composed of an LED 31 and a light receiving section 3-3 (see FIG. 2).

The range detection unit 4 detects the left end position and right end position from which the image signal is read from the signal detected by the position detection element 3.

The reading control section 5 controls the reading section 6 so as to read the image signal corresponding to the reading range (the range sandwiched between the left end and the right end) notified by the range detection section 4.

The reading unit 6 reads the original 1 read by the CCD 2.
The image signals in the range controlled by the reading control section 5, that is, the image signals in the range sandwiched between the designated left end position and right end position are read out from among the image signals.

The printer section 7 prints the image signal read by the reading section 6 or the image signal received and restored by the data restoration section 10 on recording paper.

The data compression section 8 compresses the image signal input from the reading section 6.

The transmitting/receiving unit/protocol control 9 modulates the compressed image signal and transmits it to the line, and demodulates the signal received from the line.

The data restoration unit IO restores the received image signal and returns it to the original image signal.

FIG. 2 shows an example of detecting a designated position. In this case, a scanning LED 3-1 is provided in the panel portion where the original document 1 is inserted into the facsimile machine 11, and the scanning LED 3-1 is scanned and sequentially turned on. Then, the light receiving unit 3-3 specifies the left end position and right end position to be transmitted as an image signal in the document 1,
The signal detected at this time is input to the range detection section 4 in FIG.
The left '5Ra position and the right end position are respectively detected.

Next, the configuration and operation of the range detection section 4 and the position detection element 3 will be explained using FIGS. 3 and 4.

In FIG. 3, the light emitting unit 3-2 has a plurality of light emitting elements such as LEDs arranged in the width direction of the document as shown in the scan LED 3-1 in FIG.

This light emitting section 3-2 is controlled to emit light at the positions (timings) shown in scan timings l to n in FIG. 4, respectively.

The light receiving section 3-3 is the light receiving section 3-3 in FIG. 2, and receives the light sequentially emitted by the light emitting section 3-2. This light receiving section 3 is placed at the position of ED31 for scanning in FIG. 2 corresponding to the left and right end positions to be read from the document I.
-3, and a setting instruction is given to detect signals at the left end position and right end position.

The reference timing generator 4-1 generates the reference timing signal shown in FIG.

The scan timing generating section 4-2 supplies signals as shown in scan timings 1 to n in FIG. 4 to the light emitting elements 1 to n constituting the light emitting section 3-2, respectively.

The scan comparison section 4-3 compares the light received by the light receiving section 3-3 with the timing supplied from the reference timing generation section 4-1 to the scan timing generation section 4-2, and sets it to -I. For example, the positions indicated as the left end and right end in the light reception timing in FIG. 4 are detected.

Next, the operation will be explained.

The scan timing generator 4-2 synchronizes with the reference timing signal sent from the ill i quasi-timing generator 4-1, and the scan timing generator 4-2 activates the light emitting unit 3-2 (scanning LED 3-2 in FIG.
1) Each element is caused to emit light in sequence.

(2) Place the light receiving unit 3-3 at the position corresponding to the left end position and right end position where image No. 43 is taken out from the original, and when position detection is sequentially instructed, it will correspond to the left end and right end as shown in the light receiving signal in Figure 4. signals are detected sequentially,
The data is input to scan comparison units 4-3.

(3) The scan comparison unit 4-3 compares the human-horned reception timing signal with the reference timing signal, and detects the matching left end position and right end position. As a result, the specified left end position and right end position are detected, and the image in the range sandwiched between these positions is read from the document by the reading unit 6.

Next, using FIG. 5, the CCD reading range and the captured data captured from the original document according to this embodiment will be explained.

In FIG. 5, the width of the image signal read from the original l by the CCD 2 is the entire range as shown.

Then, according to this embodiment, as described above, by specifying the left end position and right end position at which image signals are read from the document, the illustrated read data of the range sandwiched between the specified left end position and right end position is captured. . Therefore, like line printer paper for computers,
If printing starts from a predetermined position on the left end, and each line is short and the margin on the right end is large, if you send this as is to a facsimile machine, it will be slightly larger than the 4 size, so the recipient's facsimile machine will be unable to print. Conventionally, when the recording paper is A4, the entire image is transmitted in a reduced size and printed on the recording paper in a small size on the receiving side, making it difficult to see. According to this embodiment,
By specifying the left end and right end and extracting the image signal in the range between these, you can avoid being reduced (
, because it is sent as is and printed on recording paper on the receiving side.
Easy to see! In addition, when transmitting original 1, (1) the part of original 1 to be sent is detected by light receiving section 3-3;
Set points (set left and right edges).

(2) Enter your phone number and make a call.

Through the above operations, the image of the range sandwiched by the two points set in (1) on the original 1 is transmitted to the destination facsimile machine.

〔Effect of the invention〕

As explained above, according to the present invention, since a configuration is adopted in which images within the designated left and right edges of the original are captured and transmitted or copied, it is possible to avoid reducing the image of the original. .

In particular, when there is a margin at the edge of a document, by specifying the left and right edges of the range in which significant characters are printed in the document, and reading, transmitting, or copying the image signals of these specified ranges, It is possible to send or copy an image that is easy to see without reducing it.
