Description

[Detailed description of the invention] The present invention relates to a facsimile device that can obtain a received image by shifting it to one end of the recording paper when a document with a width less than a specified size is set in the center of the document setting position. .

A facsimile device can transmit not only originals of sizes specified for the device, such as A3 size and B4 size, but also documents of smaller sizes not specified for the device.

Assume that FIG. 1A shows a document 1A having the same width as specified by a certain facsimile machine, and FIG. 1B shows a document 1B having a narrower width. The facsimile signal for the original 1A has a configuration as shown in FIG. 2A. In other words, the image signal 3A following the synchronization signal 2
All represent image information regarding the original 1A. When such a facsimile signal is received by the receiving device, a received image 4A recorded on the entire surface of the recording paper is obtained as shown in FIG. 3A.

On the other hand, if the facsimile device on the sending side uses, for example, a paper width setting guide to set a document 1B of a specified size or less at the center of the document setting position, the facsimile signal will have a configuration as shown in FIG. 2B. That is, the image signal 3B representing image information about the original 1B appears only in the central portion of the image signal inserted between the two synchronization signals 2. As a result, when such a facsimile signal is received by the receiving device, a received image 4B with unnecessary portions 7 and 8 on both sides of the recording paper is obtained as shown in FIG. 3B. Therefore, in this case, the operator needs to cut the recording paper at two locations in the vertical direction (sub-scanning direction) in order to remove the unnecessary portions 7 and 8.

Of course, in this case, if the paper width setting guide is set to the specified size and the document is set by aligning one end of the document 1B with one end of the guide, the image signal 3C representing the image information as shown in FIG. It comes into contact with either side of the synchronization signal 2. As a result, for example, in the case of a facsimile signal having a configuration as shown in the figure, a received image with an unnecessary portion 9 at the right end of the recording paper is obtained. In this case, the operator can remove the unnecessary portion 9 by cutting the recording paper at one location. However, it is not preferable to set the original on the transmitting side device so that it is biased to one end in this way from the viewpoint of resolution and uniformity of light amount. Therefore, such a method cannot be used in applications where high image quality is required, such as when seal impression certification is performed by facsimile transmission.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a facsimile device that only requires cutting the recording paper in the vertical direction at one location when a document smaller than a specified size is set in the center of the document setting position. With the goal. The present invention achieves this objective by equipping a facsimile apparatus with means for recording a received image by moving it by a predetermined amount in the horizontal direction (main scanning direction) of the recording paper.

The present invention will be described in detail with reference to Examples below.

FIG. 4 shows a facsimile device on the transmitting side in one embodiment of the present invention. This facsimile apparatus 10 is provided with two interlocking paper width setting guides 12 and 13 for setting the original 11 at the center of the original setting position regardless of the size. The operator sets the paper width setting guides 12 and 13 to be equal to the width of the document 11. The person who handles this is manuscript 1
1 into the insertion slot 14 along with the paper width setting guides 12 and 13, and operate the operation panel 15. As a result, the facsimile device 10 on the sending side starts a series of operations for transmission. At this time, the facsimile device 10 transmits information regarding the scanning line density and the width of the document 11 as a mode signal to the facsimile device on the receiving side. The information regarding the width of the document 11 consists of, for example, a binary code representing how far one of the paper width setting guides 12 is set from a specific position. When preparations for the facsimile device on the receiving side are completed and both facsimile devices are synchronized, the facsimile device 10 on the transmitting side starts transmitting the image signal.

FIG. 5 shows a facsimile device on the receiving side in this embodiment. When this facsimile device 16 receives the mode signal, it writes information regarding the width of the document 11 into a width setting memory (not shown).

FIG. 6 shows the image signal processing circuit of the facsimile device 16 on the receiving side. When an image signal 19 arrives from the facsimile device 10 (FIG. 4) on the sending side, an input timing circuit 21 that counts input clock signals 20 and determines the input timing of the image signal 19 outputs a write signal 22 at a predetermined timing. , the image signals for one scanning line are sequentially written into the buffer memory 23. This written image signal is read out by a readout signal 26 outputted from an output timing circuit 25 that counts the output clock signal 24 and determines the recording scan timing.
This becomes an output image signal 27. At this time, the contents of the width setting memory are also read out and applied to the output timing circuit 25 as a document switching signal 28 to determine the timing at which the readout signal 26 is output. That is, for an original whose width is narrower than the specified size, the output image signal 27 is read out from the buffer memory 23 half the time required to main scan a distance corresponding to the difference from the width of the specified size. As a result, a received image in which one end of the received image coincides with the scanning start end of the recording paper 17 is obtained. On the other hand, if the output image signal read from the buffer memory 23 is delayed by the same amount of time, a received image is obtained in which the other end of the received image coincides with the end of scanning of the recording paper 17.

Among the above, a case in which the output image signal is advanced by half the difference between the width of the recording paper 17 and the width of the document will be specifically described. At present, the received image signal is stored in the buffer memory 23 as shown in FIG. 3B.
However, the image signal is stored for one line, and readout and storage are repeated one after another. Now, when one line of image signal is stored (FIG. 7a), the output timing circuit 25 determines the timing Tb at which the recording section (not shown) starts recording one line (FIG. 7b).
Therefore, the readout signal 26 (FIG. 7c) is output earlier by half the difference W between the width of the recording paper 17 and the width of the document. The output timing circuit 25 is given the document width W _G from a memory (not shown) as a document switching signal 28, and the output timing circuit 25 itself has reference value information corresponding to the recording paper width W _K. There is. The output timing circuit 25 creates a difference between the reference value information and the original switching signal 28, and outputs the read signal 26 as early as half of this difference. Assuming that the recording section starts recording every time n output clock signals 24 (FIG. 7d) arrive,
Since n pieces _and W _K correspond, n: W _{K =} Output. As a result, a recorded image as shown in FIG. 3C is obtained.

In the above, the communication control section (not shown) is a detection means for detecting document width information according to a predetermined protocol, and includes an output timing circuit 25 and a buffer memory 2.
3 constitutes received image signal transmission control means. Further, the output timing circuit 25 also serves as a difference detection means.

The receiving side facsimile device 16 is equipped with an automatic cutter 29 as shown in FIG. 5, which cuts the recording paper 17 when it is ejected by the feed roller 30. The movement position of the automatic cutter 29 is set according to the contents written in the width setting memory so as to cut the boundary between the received image and the unnecessary portion. Therefore, there is no need to further cut the ejected received image.

As described above, according to the present invention, the recording paper only needs to be cut in one place in the longitudinal direction, which reduces the work of the operator.
Furthermore, when an automatic cutter is provided in a facsimile machine, there is an advantage that the control and structure of the cutter is simple because cutting only needs to be done at one location.

In this embodiment, the width of the document was calculated using a paper width setting guide, but it is also possible to scan the document on the sending side, determine the scanning width of the document, and calculate it using the facsimile device on the sending or receiving side. You can.
Furthermore, in a facsimile machine that uses different cassettes for each size or type of original, the cassette may be provided with different claws depending on the width of the original, thereby allowing the sending device to determine the width of the original.
Of course, there is no need to automatically detect the width of the document in this way; even if the operator inputs information about the width of the document from the operation panel and transmits it to the facsimile machine on the receiving side. Of course it's a good thing.
