Abstract

PURPOSE:To prevent the unnecessary reduction of picture data by transmitting the size of a recording paper till then to a transmitting side as the size of the temporary recording paper so as to make the transmitting side set the reduction ratio of the picture data when the exhaustion of the recording paper is detected in the course of the reception or the output of the picture data. CONSTITUTION:When the end mark of the recording paper is detected in the couse of processing (101), and a system falls into the exhaustion state of the recording paper, the size of the loaded recording paper is detected (105), and is transmitted to the transmitting side (106), and the transmitting side is made to set the reduction ratio, and henceforth, the picture data transmitted from the transmitting side is received and stored in a memory. After the memory reception of the picture data of all pages is finished, a line is cut off. Namely, when the exhaustion of the recording paper occurs, memory interception is performed automatically on the assumption that the recording paper of the same size as the recording paper loaded at present is supplemented temporarily. Accordingly, such trouble that the picture data reduced on the assumption that the recording paper of other size is supplemented is received can be eliminated.

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a memory proxy receiving method in a facsimile machine, and more specifically, when recording paper is used up, recording paper of the same size as that which has been installed up to that time is installed. The present invention relates to a device having a characteristic that it is configured to receive a memory as a substitute.

[0002]

2. Description of the Related Art Facsimile devices have been developed and used in which receiving recording paper (heat-sensitive roll paper) of A4 width or B4 width can be replaced and set according to the user's usage. .. In such a facsimile device, the reception recording paper size is transmitted from the reception side to the transmission side before the image data is transmitted, and the transmission side compares the transmission document size with the reception recording paper size. Then, when the size of the transmitted document exceeds the size of the received recording paper, the image data is reduced and transmitted.

For example, as shown in FIG. 4 (a), if the transmission original is A4 size, whether the thermal roll paper on the receiving side is A4 width or B4 width, it is read from the transmission original. The image data is transmitted as it is. Further, as shown in FIG. 4B, when the transmission original is B4 size, when the receiving side thermal roll paper is A4 width, the image data read from the transmission original is displayed. On the other hand, when the thermal roll paper on the receiving side has a B4 width, the image data read from the transmission original is transmitted as it is. The image information is completely transmitted and printed out.

By the way, in such a facsimile machine, if the recording paper of the facsimile machine on the receiving side runs out during the transmission of image data, it is assumed that the recording paper of either A4 size or B4 size is temporarily set. There is a memory proxy reception function that transmits the recording paper size to the transmitting side to set the reduction ratio and then stores the received image data in the memory.

FIG. 5 (a) schematically shows such a memory proxy reception function. In the case of performing the memory proxy reception assuming that a recording sheet of A4 width is temporarily set, from the transmission side. The transmitted image data of A4 size is directly received and stored in the memory, and the image data stored in the memory is printed out as it is on the recording paper regardless of whether the replenished recording paper is A4 size or B4 size. ..

Further, as shown in FIG. 5B, B4
In the case where the memory proxy reception is performed assuming that the width of the recording paper is set, the A4 size image data transmitted from the transmitting side is directly received and stored in the memory, and the replenished recording paper has the width of B4. For example, the image data stored in the memory is printed out as it is, but when the replenished recording paper has an A4 width, the image data stored in the memory is reduced and printed out at a predetermined reduction ratio.

Further, as shown in FIG. 6A, B4
In the case of performing the memory proxy reception assuming that the width of the recording paper is set, the B4 size image data transmitted from the transmitting side is directly received and stored in the memory, and the replenished recording paper may be the B4 size. For example, the image data stored in the memory is printed out as it is, but if the replenished recording paper is A4 size, the image data stored in the memory is reduced at a predetermined reduction ratio and printed out. ing.

However, as shown in FIG. 6B,
When transmitting a B4 size document to a medium for proxy reception with A4 size recording paper set, the image data read from the B4 size transmission document is transmitted at the transmission side at a predetermined reduction ratio. Since the data is transmitted to the receiving side after being reduced, only the reduced image data can be printed even if the receiving side supplements the recording paper of B4 size, and the image quality is impaired due to unnecessary reduction. It was

SUMMARY OF THE INVENTION The present invention proposed in view of the above circumstances reduces unnecessary image data by referring to the size of the recording paper currently mounted when the recording paper runs out. SUMMARY OF THE INVENTION It is an object of the present invention to provide a memory proxy receiving method for a facsimile apparatus, which reduces the occurrence of the above.

[0010]

SUMMARY OF THE INVENTION The present invention proposed to achieve the above object is mounted by the time when a paper-out condition of a recording paper is detected during image data reception and printout. The size of the recording paper is transmitted to the transmitting side as a temporary recording paper size to set the reduction ratio of the image data, and thereafter, the image data transmitted from the transmitting side is sequentially received in the memory. ..

[0011]

According to the present invention, when the out-of-paper state of the recording paper is detected during the reception of the image data and the printing output, after the reception of the image data of the page and the printing output are completed, the recording that has been mounted by then The paper size is detected, and the detected recording paper size is transmitted to the transmitting side as a temporary recording paper size to set the reduction rate of the image data.After that, the image data transmitted from the transmitting side is sequentially stored in the memory. To receive. Therefore, if a recording paper of the same size as the one loaded up to that time is replenished, the recording paper of A4 size is replenished although the same B4 recording paper is intended to be replenished. As a result, the disadvantage that only the reduced image data can be received is eliminated, and unnecessary reduction can be reduced.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a flow chart showing an outline of the memory proxy receiving method of the present invention. The operation will be described with reference to the drawing. The procedure necessary for the reception of image data (data mutual transmission) is executed by the handshake. After that, the normal operation of receiving the image data of one page and printing out on the recording paper is repeated until the image data of all the pages are received. When the image data of all pages have been received and printed out, the line is cut off. However, during the above process, when the recording paper end mark (a black belt mark printed in advance at the end of the recording paper as described later) is detected and the paper runs out, the recording paper attached at that time is detected. The size (recording paper width) is detected and transmitted to the transmitting side, whereby the transmitting side sets the reduction ratio, and thereafter, the image data transmitted from the transmitting side is received and stored in the memory. In this way, when the memory reception of the image data of all pages is completed, the line is cut off. (See steps 100 to 108 in FIG. 1).

As described above, according to the method of the present invention, when a paper shortage occurs, the memory proxy reception is automatically performed assuming that the recording paper of the same size as the currently mounted recording paper is temporarily replenished. Although the same B4 recording paper as before is intended to be replenished, there is no inconvenience that the reduced image data is received as the A4 size recording paper is replenished.

2 (a) and 2 (b) show the essential structure of the facsimile apparatus for carrying out the present invention described above. The A4 width and the B4 width are detected from the center of the heat-sensitive roll paper P. As shown in FIG. To the recording paper P on which the reflective recording paper sensors S1 and S2 for detecting the black stripe B (recording paper end mark) previously printed on the end portion of the thermosensitive roll paper P are conveyed. The structure is such that they are opposed to each other.

Next, FIG. 3 is a flow chart showing a more detailed operation of the method of the present invention, which will be described with reference to the drawing. When a call signal is transmitted through the telephone line, the line is connected to receive an incoming call. When a CNG signal (calling tone) is transmitted from the calling side, a CED signal (callee terminal identification signal) is returned from the called side, and phase A for starting facsimile transmission is executed. When the black band B of the recording paper P is not detected by the paper break sensor S3, the recording paper size currently mounted is detected by the recording paper sensors S1 and S2, and necessary data including the detected recording paper size data is transmitted. Phase B is performed for mutual transmission by handshake with the side. Thereafter, the operation of receiving the image data of one page that is transmitted and printing it out is repeated until it is determined in the subsequent phase D that there is no image data of the next page. Note that once the phase B is executed, the phase B after the second time is skipped. In this way, receiving the image data of all pages,
When the print output is completed, the line is cut off by phase E and the system returns to the standby state. On the other hand, when the black band B of the recording paper P is detected by the paper shortage sensor S3 during the process of 1, the recording paper sensor S
1 and S2, the size of the currently installed recording paper is detected, and phase B is performed in which necessary data including the detected recording paper size data is mutually transmitted by handshaking with the transmitting side. Thereafter, the operation of receiving the transmitted image data of one page in the memory is repeatedly performed until it is determined in the subsequent phase D that there is no image data of the next page. In this way, when the memory reception of the image data of all the pages is completed, the line is cut off by the phase E to return to the standby state. (The above is steps 200 to 215 in FIG.
reference).

In the above description, the size of the recording paper loaded is detected when the paper runs out. However, before the paper runs out, the size of the recording paper is stored in a memory or the like in advance. It is also possible to keep it.

In the above description, the heat-sensitive roll paper is used as a premise, but the method of the present invention can also be applied to standard-size recording paper. For example, the standard-size recording paper size is preset before the paper runs out. It is also possible to store the above, and when the paper runs out, the stored fixed-size recording paper size data is transmitted to the transmitting side to perform memory proxy reception.

[0018]

As will be understood from the above description, according to the memory proxy receiving method of the present invention, when a paper shortage occurs, a recording paper of the same size as the recording paper that has been installed up to that time is temporarily installed. Since the memory proxy reception is automatically performed as if it had been loaded, if the recording paper of the same size as that loaded before is replenished, the same B4
A4 despite intending to replenish the recording paper
Only the reduced image data can be received because the recording paper of the size is replenished, and unnecessary reduction of the image data can be prevented in advance.
