Abstract

PROBLEM TO BE SOLVED: To prevent image deviation and image absence due to a difference in the size system between an original and recording paper by providing an original size information means which informs reception-side facsimile equipment of the original size with a specific signal of facsimile protocol. SOLUTION: Transmitting facsimile equipment measures the width and length of an original so as to determine the original size at the time of transmission and determined transmission size according to those two data. Once the transmission size is determined, a scanner 3 reads the original and in memory transmission mode, the read data are stored in a RAM 4, compressed by a DCR 5, and transmitted through an NCU 6. The Reception-side equipment, on the other hand, receives the image data through an NCU 5 and stores the data in a RAM 4 through a DCR 5, and the data are printed out on a plotter 7. At this time, an NSS or DCS signal which is sent from transmission side is received to recognize whether the received image data is of a letter system or A4 system, and the received image data are outputted by an output method matching the received image data.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine and a copying machine, and more particularly, it records the image data of a letter-based document such as a letter or double letter on an A4 type recording sheet such as A4, A3, B4. Or, conversely, it relates to control when recording image data of an A4 type original on a letter type recording paper.

[0002]

2. Description of the Related Art In a facsimile machine, a non-standard protocol is used in order to notify the receiving side of what transmission conditions (modem speed, I / O speed, document width etc) are used for transmission. Signal NSS (Ricoh specification) or CCITT specification standard signal DCS (G3
Specifications) are used.

In the protocol of such a facsimile machine, the paper width declaration is A3 width in CCITT specifications,
Since there are three types of B4 width and A4 width, the letter width (216
A document of (mm) is handled as an A4 width (210 mm).

For this reason, when the receiving side uses A4 recording paper, if the center registration is specified as the writing registration value, 3 mm on the left and right of the image is cut off, and if the left end is specified, the image is biased to the right, Right end 6
mm may be missing.

Similarly, in a copying machine, when the original is a letter size and the recording paper is an A4 size and the same size copying is performed as it is, the left and right 3 mm of the image is missing or the right edge of the image is 6 mm. It will be chipped. Note that the operator can set the lateral (width direction) and vertical (length direction) magnifications independently to record a letter size original on A4 size recording paper, but this operation is cumbersome and The fact is that the functions are rarely used.

On the other hand, Japanese Patent Laid-Open No. 5-227394 discloses a plotter capable of selectively performing inch-based recording and millimeter-based recording on cut sheets of a standard size.
A facsimile apparatus is disclosed in which a reduction unit that thins out lines in the sub-scanning direction is provided when the size of image data does not fit within a cut sheet so that the image data fits within the recording sheet.

Further, in Japanese Patent Laid-Open No. 61-242168, the received image is reduced in the sub-scanning direction at a reduction ratio corresponding to the length of the received image and the length of the recording paper and recorded on the recording paper. There is disclosed a facsimile apparatus capable of appropriately recording even when an image longer than a recording sheet is received.

[0008]

As described above, in the conventional facsimile apparatus or copying apparatus, if the size of each original is different and the recording sheet is A4 type, the image is projected from the recording sheet. The problem of chipping arises. In particular, since the letter type is used as a standard overseas in North America and the like, when receiving from abroad or sending to overseas, there is a problem that image bias or image cutout occurs due to difference in paper size type. there were.

Note that reduction by thinning or the like as disclosed in JP-A-5-227394 and JP-A-61-2242168 described above is possible because the process becomes complicated and the image is deteriorated. I don't want to use it alone.

Therefore, the present invention has been made in order to solve such a problem, and provides a facsimile apparatus capable of preventing image deviation and image breakage caused by a difference in size system between a document and a recording sheet. The purpose is to do.

FIG. 5 is a flowchart showing the processing contents of the PU 1, and FIG. 5 is a flowchart showing the processing contents of the CPU 1 in the receiving side facsimile apparatus.

First, the transmission side facsimile apparatus shown in FIG. 1 measures the document width and the document length in order to determine the document size during transmission, and determines the transmission size based on these two data (FIG. 4). Processing 101).

When the transmission size is determined, the original is read by the scanner 3 (process 102). In the case of memory transmission, the read data is stored in the RAM 4, compressed by the DCR 5 and transmitted via the NCU 6 ( Processing 1
04).

In the present embodiment, a bit for notifying whether the transmission image data is letter type or A4 type is set in the protocol at the time of transmission (process 103), and the receiving side outputs by this bit. To judge.

A signal suitable for setting this bit is a non-standard signal that informs the receiving side at what transmission conditions (modem speed, I / O speed, document width etc) for transmission. NSS (Ricoh specification) or C
There is a standard signal DCS (G3 specification) of CITT specification.

Further, as a method of judging whether the manuscript is a letter type or an A4 type, The paper width sensor automatically determines by the facsimile device. 2. A changeover switch is provided on the operation port so that the operator can change the size according to the document size at the time of transmission. 3. An internal switch (serviceman mode) enables fixing to either letter type or A4 type according to the user's request. And so on.

On the other hand, in the receiving side facsimile apparatus shown in FIG. 2, when receiving, the image data is transferred to the DCU via the NCU 6.
After passing through CR5, it is stored in the RAM 4 and printed out by the plotter 7.

At this time, the NSS or DCS signal sent from the transmitting side facsimile apparatus as described above is received (process 201 in FIG. 5) to recognize whether the received image data is letter type or A4 type ( In step 202), output is performed by an output method (recording paper selection, writing registration, etc.) according to the received image data.

That is, it is checked whether or not the scaling process by changing the speed of the polygon motor is necessary (decision 203), and the relationship between the received image and the recording paper is the letter system to the letter system,
Alternatively, if there is a match such as the A4 system to the A4 system (N in the determination 203), it is determined from the relationship between the received image and the size of the recording paper, and processing such as standard scaling, rotation, and division is performed as usual. Output.

On the other hand, when the received image and the size system of the recording paper do not match, in addition to the conventional recording paper selection method, the rotation speed of the polygon motor is controlled to perform the image scaling processing (decision 203). Y → process 204).

In this variable magnification processing, when the speed is output slower than the rotational speed of the polygon motor at the time of print output and equal magnification, the output image is reduced in the main scanning direction and enlarged in the sub scanning direction. It That is, the magnification of the output image uses a characteristic that is proportional to the rotation speed of the polygon motor in the main scanning direction and inversely proportional to the sub scanning direction.

A method of setting the polygon motor speed for each recording paper size for each original size will be described below.

1. Manuscript is letter length (216mm × 279m)
m, the following mm is omitted), and the recording paper is A4 portrait (210 x
In case of 297), the polygon motor speed at the same size output is V
o, if the changed polygon motor speed is Vc, then Vc = 210/216 · Vo≈0.972Vo. At this time, the 216 × 279 image is 210 ×
Since it is scaled to an image of 287 (287≈279 / 0.
972), fits perfectly on A4 portrait recording paper. Therefore,
It is possible to prevent image deviation and image cutout due to the difference in the size system of the original and the recording paper, and it is easy to realize because it uses the variable magnification characteristic by changing the speed of the polygon motor without depending on the thinning process. It is possible to prevent deterioration of the image.

2. The manuscript is vertical letter (216 x 279)
When the recording paper is rotated and output in A3 portrait (297 × 420) or A4 landscape (297 × 210), Vc = 297/279 · Vo≈1.065Vo. At this time, the 279 × 216 image is 297 ×
The image is scaled to 203 (203≈216 / 1.06)
5).

3. The manuscript is next to the letter (279 x 216)
When the recording paper is A3 portrait (297 × 420) or A4 landscape (297 × 210), the same as in the above case 2.

4. The manuscript is next to the letter (279 x 216)
When the recording paper is B4 portrait (256 × 364), Vc = 256/279 · Vo≈0.918Vo. At this time, the 279 × 216 image is 256 ×
235 images are scaled (235≈216 / 0.91
8).

5. When the original is A4 portrait (210 × 297) and the recording paper is letter portrait (216 × 279), Vc = 216/210 · Vo≈1.029Vo. At this time, a 210 × 297 image is 216 × 2
It is scaled to 89 images (289≈297 / 1.02)
9). In this case, the image is still over in the vertical direction of the recording paper only by the scaling processing by changing the polygon motor speed. In order to prepare for such a situation, in this embodiment, FIG.
After the processing 204 of step 207, it is checked whether or not thinning processing is necessary (decision 205), and if the image overshooting occurs as described above (determination 205 Y), thinning out is performed so that the image is not overwhelmed. After performing the process (process 206), the printout is performed (process 207). Since the scaling process by changing the polygon motor speed is preferentially performed and the thinning process is performed as necessary, the image deterioration due to the thinning process can be minimized.

6. The document is A4 portrait (210 x 297),
When the recording paper is rotated horizontally in the letter horizontal direction (279 × 216) or double letter vertical direction (279 × 432), Vc = 279/297 · Vo≈0.939Vo. At this time, the image of 297 × 210 is 279 ×
224 images are scaled (224≈210 / 0.93
9). In this case, the recording paper is double-letter portrait (27
9 × 432) is fine, but next to the letter (279 × 21)
In case of 6), the image is overlaid in the vertical direction of the recording paper.
In this case as well, similarly to the above, the thinning-out processing is performed so that the image is not overexposed (processing 206), and the print output is performed (processing 207).

7. The document is A4 landscape (297 x 210),
When the recording paper is letter horizontal (279 × 216) or double letter vertical (279 × 432), it is the same as in the above case 6.

8. The original is B4 vertical (256 x 364),
When the recording paper is letter horizontal (279 × 216) or double letter vertical (279 × 432), Vc = 279/256 Vo≈1090 Vo. At this time, a 256 × 364 image is 279 × 3
The image is scaled to 34 images (334≈364 / 1.09)
0). In this case, as in the case of 6 above, there is no problem if the recording paper is double-letter portrait (279 × 432), but the letter landscape (279
X216), the image is overlaid in the vertical direction of the recording paper. Also in this case, similarly to the above, after the thinning processing is performed so that the image is not over (process 20).
6), print output (process 207).

FIG. 6 is a flow chart showing the main part of a facsimile apparatus according to another embodiment of the present invention, and the apparatus configuration is the same as that shown in FIGS. The receiving party determination means and the scaling processing means according to claim 2 are realized by the CPU 1.

In the present embodiment, a specific receiving party using a document of a size system different from that of the recording paper of its own is designated as R in advance.
It is registered in AM4 etc., and when received from the registered destination, it is judged that the received image is of a size system (letter system vs. A4 system) different from the recording paper of its own machine, and the scaled output is performed. To do. The scaling method is the same as in the above embodiment.

That is, as shown in the flowchart of FIG. 6, when a facsimile is received, it is first checked whether the receiving party is a registered party (decision 30).
1). If it is registered (Y in judgment 301), the scaling process is performed by changing the polygon motor speed as described above (process 302). Then, similarly, it is checked whether or not the thinning process is necessary, and if it is not necessary, it is directly printed out (N in judgment 303 → process 305), and if necessary,
Printing is performed after thinning processing is performed (Y in determination 303 → process 304 → process 305). According to this embodiment, the same effect as that of the above embodiment can be obtained, and since the facsimile protocol can be the same as the conventional one, there is an advantage that it can be easily realized.

4, the method of distinguishing between double letter and letter type such as A3 or A4 type is 1. The copying machine automatically discriminates by the paper width sensor. 2. The operator makes a judgment and makes a judgment by switching a switch or the like set on the operation port. And so on.

In this manner, when it is recognized whether the original is the letter type or the A4 type, the print method is performed by the output method (recording paper selection, writing resist, etc.) adapted to the size type of the original.
That is, it is checked whether or not the scaling processing by changing the polygon motor speed is necessary (determination 402), and the relationship between the original and the recording paper is the same as the letter system for letter system or the A4 system for A4 system. If (decision 4
02 N), as is conventional, it is judged from the relationship between the size of the original and the recording paper, and output using processing such as standard variable magnification and rotation.

In this way, after performing the scaling processing by changing the polygon motor speed, it is checked whether or not the thinning processing is necessary (decision 404). If the thinning-out process is not necessary, it is printed out as it is (N in judgment 404 → process 4).
06), if necessary, perform thinning processing and then print out (Y in judgment 404 → processing 405 → processing 40).
6).

According to this embodiment, even in the copying machine,
The same effect as that of the above-described embodiment is obtained, and the troublesome operation is reduced.

When the original is A4 size (210 x 297) and the recording paper is letter size (216 x 279), the width direction is 216/210 ≈ 1.029 (enlarged to about 103%) Length direction: 279/297 ≈ It becomes 0.939 (reduced to about 94%). 4. When the original is A3 size (297 x 420) and the recording paper is double letter size (279 x 432), width direction: 279/297 ≈ 0.939 (reduced to about 94%) Length direction: 432/420 ≈1.029 (enlarged to about 103%).

Further, the processing by the independent variable magnification can be applied to the above-mentioned facsimile machine and is effective for the facsimile machine having a plotter such as thermal recording which does not use a polygon mirror.
