However, depending on the reading mechanism of the transmitter of the facsimile apparatus, there is a reading mechanism that moves to one side, and the A4 recording paper 21 is disposed on one side in the transmission width of 216 mm.
Document information of 0 mm is distributed and transmitted. In this case, in the receiving-side facsimile apparatus that prints 210 mm at the center, the image information at one side end of 3 mm is lost.

When image information is sent using a letter-based transmission original, since the letter width is 216 mm, when the image information is recorded on A4 recording paper (paper width 210 mm), the image information data is lost by 6 mm. Will be done.

To solve such a problem, for example, it is conceivable that a framed and printed document is used as a transmission document, and the receiving side detects a frame in an image to determine the position of the transmission document.

Also, as disclosed in Japanese Patent Application Laid-Open No. 9-83786, at the time of transmission, original size information indicating whether the original size is A4 recording paper type or letter type is added to a predetermined signal in the facsimile protocol at the time of transmission. The receiving facsimile apparatus notifies the receiving facsimile apparatus whether the image size of the received image data is A4 recording paper type or letter type based on the document size information notified from the transmitting side. It has been proposed to perform a scaling process or the like based on the result to prevent image bias or image cutoff caused by a difference in size between the original and the recording paper.

[0008]

However, in these measures, it is necessary to insert a specific image such as an entry frame in a transmission image, and original size information indicating an A4 recording paper system or a letter system is transmitted from the transmitting facsimile machine. Has to be notified to the receiving facsimile machine.

According to the present invention, the definition of the A4 width in facsimile communication is 216 mm according to the letter system, whereas the actual width of the A4 recording paper is 210 mm. It is an object of the present invention to provide a facsimile apparatus capable of avoiding the problem of bias and image disconnection based on image information on the receiving side.

[0020]

An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing a configuration of a facsimile apparatus according to an embodiment of the present invention. In FIG. 1, a document reading unit 11 reads an image of a document set on a reading table, and stores the read image data in a reading memory 12. The read image data is transmitted to the modem 1
The data is transmitted to the facsimile machine at a predetermined destination via the network controller 3a and the network controller 13b. Also, the image data transmitted from the transmission source is received via the modem unit 13a and the network control unit 13b.

The management memory 14 stores data for managing the operation of the facsimile machine. The page memory 15 is configured to hold image information data transmitted from a transmission source at the time of reception, and to perform read control when necessary such as at the time of recording, and to store at least one page of received image information data. Have the capacity.

The operation unit 16 inputs operation data for operating the facsimile machine and displays information for the operation. The received image information data is read from the page memory 15 and recorded in the recording unit 17b via the plotter control unit 17a. At this time, an arbitrary position can be designated as a writing start position of the received image information data.

The main control unit 18 includes a CPU, a ROM, and a RAM.
And the above-described original reading unit 11 to the recording unit 17
The operation of the facsimile apparatus is controlled, including b.

Now, while the definition of A4 width in facsimile communication is 216 mm according to the letter system,
Since the actual width of A4 recording paper is 210 mm,
The recorded image is deviated or the image is cut off.

FIG. 2 is a diagram showing a positional relationship of image information data for explaining such a state. FIG. 11A shows a case where the transmission original of A4 recording paper is arranged at the center of the transmission width W1 (216 mm) in A4 width image information communication, and the width W2 (210
mm) A4 recording paper is arranged so as to print 210 mm at the center. As described above, when the A4 recording paper is arranged at the center of the transmission width W1 in the A4 width image information data communication as usual on both the transmission side and the reception side, image information data can be correctly received.

However, as shown in FIG. 2B, the width W2 (2
10 mm) A4 recording paper transmission original, one end of the transmission width W1 (216 mm) on A4 communication (left end in this case)
, The recording paper of the receiving-side facsimile apparatus is placed in the center of the transmission width W1 in the usual manner.
In a situation where the image data is arranged so as to print mm, image information corresponding to 3 mm at one end is missing as indicated by a broken line.

In the facsimile apparatus according to the first embodiment of the present invention, the number of black dots included in the same width at both ends of the received image information is measured, and the number of black dots included in the same width at both ends is measured. If there is a difference, the received image information is recorded on A4 width recording paper so as to include the end on the side where the number of black dots is large. As described above, the state in which the received image information data is arranged on one side is automatically determined, and the image information is recorded on A4 recording paper in accordance with the state arranged on one side. Prevent bias and omission.

The first embodiment will be described in detail with reference to the block diagram of the facsimile apparatus shown in FIG. 1 and the flowchart shown in FIG.

When the facsimile apparatus receives the image information data, the received image information data is stored in the page memory 15. Upon completion of the reception (step S31), at least a predetermined amount (per page) of the received image information data is read from the page memory 15 in the sub-scanning direction to the main control unit 18, and the image information data stored in the page memory 15 is read out. Then, the number of black dots included in the same width at both ends is measured (step S32).

The same width at both ends of the image information data in step S32 can be set to an arbitrary width such as 1 mm, 2 mm,... 5 mm. In this case, it is preferable to set the same width at both ends to 3 mm, that is, a value obtained by dividing a difference of 6 mm between 216 mm, which is the A4 width in facsimile communication, and 210 mm, which is the paper width of A4 recording paper, by two. By setting the same width at both ends to 3 mm in this way, it becomes easier to determine the position (center, left end, or right end) where the transmission document of A4 width recording paper is arranged.

Next, it is determined whether or not the same width at both ends of the image information data, that is, the numbers of black dots included on the left end side and the right end side are substantially the same (step S33). This step S
A predetermined numerical width is given to “same degree” in 33.
If the determination is No, the process proceeds to step S34 to determine whether the number of black dots on the left end is large (step S34). Steps S33 and S34 may be determined collectively.

If the result of determination in steps S33 and S34 is YES in step S33, step S35
So that the received image information data stored in the page memory 15 is written on A4 recording paper from the position at the left end of 3 mm, that is, the image information data for the center 210 mm of the received image information data is recorded on A4 recording paper. In this case, the image information data is read from the page memory 15 and is controlled to be recorded on A4 recording paper.

If Yes in step S34, the flow advances to step S36 to write the received image information data stored in the page memory 15 to the A4 recording paper from the position of 0 mm on the left end, that is, the left end of the received image information data. From 21
Control is performed so that image information data for 0 mm is recorded on A4 recording paper.

If No in step S34, the process proceeds to step S37, in which the received image information data stored in the page memory 15 is written on A4 recording paper from the position at the left end 6 mm, that is, the received image information data is written. Is controlled so that the image information data for 210 mm from the right end of A4 is recorded on A4 recording paper.

In step S38, the designated writing position (3 mm from the left end of the image information data,
(0 mm, 6 mm), the image information data is read from the page memory 15, and the predetermined image information data is actually recorded on A4 recording paper by the recording unit 17b via the plotter control unit 17a.

Finally, as the transmission source information of the image information data, the facsimile number of the transmission source and the processing information written from the left end 0 mm or the left end 6 mm are set and stored in the management memory 14. This transmission source information is used at the time of subsequent facsimile transmission. In addition, 3mm at the left end
In the case where the data is written from the same, it may be similarly recorded.

In the first embodiment, the transmission facsimile apparatus transmits a transmission width 2 in A4 width image information data communication.
Even when original information of A4 recording paper 210 mm is arranged and transmitted on one side of 16 mm, the state of arrangement on one side can be automatically determined from the received image information. Then, the image information received on the A4 recording paper is appropriately recorded in accordance with the result of the determination, that is, whether the image is transmitted in the state of being arranged on the left end side, the right end side, or the center portion. Deviation or omission can be prevented. Further, by setting the same width at both ends to 3 mm, it becomes easier to determine whether the transmission-side original information of 210 mm A4 recording paper is arranged in the center, right or left.

FIG. 4 is a flow chart of the facsimile apparatus according to the second embodiment of the present invention.

In the second embodiment, since the recording form on the A4 width recording paper in the first embodiment is recorded and held in the management memory 14 for each transmission source of the received image information, When the image information is transmitted to the transmission source using this information, the image information to be transmitted is shifted and transmitted according to the stored recording mode. As described above, the image information to be transmitted is shifted according to the stored recording mode, so that the other party's facsimile apparatus has a mechanism in which both the recording and reading are performed on one side.
This enables transmission suited to the other party.

In FIG. 4, first, a destination of transmission from the facsimile apparatus to a destination to be transmitted is input (step S41). The input transmission destination is stored in the management memory 14.
Facsimile number and processing information (such as writing from the left end 0 mm or the left end 6 mm) as the sender information
Is retrieved as information as to whether or not it matches the destination (step S42).

Here, the source information is 0 mm at the left end.
Alternatively, when writing is performed from the left end 6 mm, the facsimile number of the transmission source and its processing information are stored in the management memory 14. Therefore, in the case of No in step S42, the process proceeds to step S43, in which the image information data of the A4 width recording paper read by the document reading unit 11 is stored at the center position of the reading memory 12, that is, the width of the A4 width image information data communication. It is stored at a position 3 mm from the left end of 216 mm.

If the input transmission destination matches the transmission source information in step S42, the processing information set with the facsimile number of the transmission source is either the left end 0 mm or the left end 6 mm. In S44, it is determined whether the recording mode is 0 mm.

In step S44, in the case of Yes, the process proceeds to step S45, where the image information data read from the A4 width recording paper is stored at a position 0 mm from the left end of the reading memory 12, that is, from the leftmost end.

If No in step S44, the flow advances to step S46 to store the image information data read from the A4 width recording paper at a position 6 mm from the left end of the reading memory 12, that is, the rightmost end side.

After reading the image information data from the A4 width recording paper to be transmitted (step S47), the width 216 of the A4 width image information data communication from the reading memory 12 is read.
The image data is transmitted to the destination facsimile device via the modem unit 13a and the network control unit 13b as mm image information data.

As described above, according to the second embodiment,
Since the image information to be transmitted is shifted in accordance with the stored recording format, the transmission according to the destination is performed even when the facsimile apparatus of the destination has a mechanism for both recording and reading to one side. be able to.

FIG. 5 is a flowchart of the facsimile apparatus according to the third embodiment of the present invention.

In the third embodiment, a letter A4
If the image information is sent using the original,
Image information data having a 4-letter width (216 mm) is recorded on A4 recording paper having a smaller width (210 mm) without missing 6-mm image information data which would be lost in normal 1: 1 recording. Therefore, when the number of black dots at both ends of the received A4 width image information is both equal to or greater than a predetermined value,
The A4 width image information is reduced and printed on A4 width recording paper.

In FIG. 5, when image information data is received by the facsimile machine, the received image information data is stored in the page memory 15. When reception is completed (step S5
1) At least a predetermined amount (one page unit is acceptable) of the received image information data is read from the page memory 15 in the sub-scanning direction to the main controller 18 so that both ends of the image information data stored in the page memory 15 have the same width. The number of black dots included is measured (step S52).

The same width at both ends of the image information data in step S52 can be set to an arbitrary width such as 1 mm, 2 mm,... 5 mm. in this case,
It is preferable to set the same width at both ends to 3 mm. By setting the width of both ends to 3 mm in this way, it becomes easier to determine whether the transmitted document is A4 letter width (216 mm) or A4 width recording paper (210 mm).
Further, when the transmission original is A4 width recording paper, it becomes easier to determine whether the original is located at the center of A4 communication, is shifted to the left end side, or is shifted to the right end side.

Next, it is determined whether or not the number of black dots included in the same width at both ends of the image information data, that is, the number of black dots included in the same width at the left end side and the right end side is greater than a predetermined value at both end sides. A determination is made (step S53).

If Yes in step S53, the document to be transmitted has an A4 letter width (216 mm).
Prepare to record at a reduced ratio of / 216. In this case, for example, the image information data stored in the page memory 15 is once read out, reduced by the reduction ratio (210/216) by the main control unit 18, and then re-stored in the page memory 1 again.
5, and stored in the recording unit 17b via the plotter control unit 17a. Further, after the image data is reduced at the reduction ratio (210/216), the recording unit
7b may be recorded.

If No in step S53, the document to be transmitted is A4 width recording paper, so the flow advances to step S54 to prepare for performing the same-size recording. In the same-size recording, the flowchart of FIG. 3 of the first embodiment described above, in particular, the processing of steps S33 to S37 can be directly employed.

In step S56, reduced recording (210/216),
Alternatively, the image information data is written by the same size recording (writing position is 3 mm, 0 mm, 6 mm, etc. from the left end of the image information data) via the plotter control unit 17a.
At b, recording is actually performed on A4 recording paper.

As the source information of the image information data, the facsimile number of the source and the reduced recording (210/2)
16) Alternatively, processing information at the writing position of 1: 1 recording (3 mm, 0 mm, 6 mm, etc. from the left end of the image information data) may be set and stored in the management memory 14. In the case where the transmission source information is stored in this manner, the image information to be transmitted is determined at the time of subsequent facsimile transmission in accordance with the stored recording format, as in the second embodiment of FIG. Since transmission can be performed by enlarging (the reverse ratio of reduction recording is 216/210) or shifting, transmission suitable for the facsimile machine of the destination can be performed.

As described above, according to the third embodiment,
A facsimile apparatus that receives A4 width image information by mounting A4 width recording paper, and measures the number of black dots included in the same width at both ends of the received image information, and detects the number of black dots included in the same width at both ends. When the number of dots is equal to or greater than a predetermined value at both ends,
It is determined that the transmission original is an A4 letter width original, and the original is reduced and recorded on the A4 width recording paper so as to include all of the received image information.

Further, when the number of black dots included in the same width at both ends is not larger than the predetermined value at both ends, it is determined that the transmission original is A4 width recording paper and the original is recorded at the same size. At the time of this 1: 1 recording, similarly to the first embodiment, A4 is placed on one side of the transmission width 216 mm from the transmission side facsimile machine.
Even when the original information of the recording paper 210 mm is arranged and transmitted, the state where the original is arranged on one side is automatically determined from the received image information. The image information is appropriately recorded on the A4 recording paper in accordance with the result of the determination, that is, whether the image information is transmitted in the left end side, the right end side, or the central portion. And omission can be prevented.
