[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal device, and more particularly to a terminal device which makes it easy to handle recorded received image information when the size of image information received via a communication line is different from the size of recording paper. Related to the device.

[0002]

2. Description of the Related Art Conventionally, in an image receiving terminal device such as a facsimile device, when the received image information is larger than the size of a recording paper, the two match, for example, as disclosed in JP-A-2-141173. The image information is reduced to a predetermined size and recorded. However, conversely, when the recording width is larger than the receiving (original) width, for example, in a facsimile apparatus using a roll-shaped recording paper (hereinafter, referred to as `` roll paper ''), it is usually at both ends. Margins occur (see FIG. 2A). In a facsimile apparatus using cut paper, margins usually occur at both ends and a lower part.
(See FIG. 2 (b).) However, no special consideration was given to this.

[0003]

As described above, if there are margins at both ends (in the case of roll paper) or both ends and the lower part (in the case of cut paper), when filing a received document, or
When copying (for filing), there is a problem that it is unexpectedly difficult to handle. The present invention has been made in view of the above circumstances, and an object of the present invention is to solve the above-described problems in the conventional technology, and to perform recording when the size of received image information and the size of recording paper are different. It is another object of the present invention to provide a terminal device which makes it easy to handle received received image information and makes effective use of recording paper.

[0004]

Comparing means, and, if the receivable width is greater than the transmission original width, means for notifying the transmission original width as the receivable width, and shifting the data for the transmission original width so as to be packed from the head of the notified original width. And a terminal device.

[0005]

In the terminal device according to the present invention, the recording start position is set to the left end of the recording paper, so that the received image information recorded in the received document can be filed or copied. The effect that handling becomes easy is obtained.

A control unit, respectively, are shown. FIG. 3 (a) and (b)
FIG. 5 is a diagram showing recorded image information of an output result of the terminal device according to the first embodiment of the present invention. Here, after receiving the image information, the reception width is printed from the edge of the recording paper.

The procedure for performing the above-described output will be described below. In the following description, A4, B
A4Y and B are the width and height of size 4
Described as 4T. FIG. 4 is a block diagram of a path at the time of reception.
Shown in FIG. 5 is an explanatory diagram relating to the above-mentioned size designation, and FIG. 6 shows a configuration example of the line buffer. In addition,
FIG. 6 shows the case of the maximum recording width A3 size.
FIG. 6A schematically shows the configuration of a line buffer having a maximum recording width of A3, where x1, x2, x3, and x4 are 1/2 of the difference between A3Y and B4Y, and B4Y and A4Y, respectively. Corresponds to one half of the difference. Basically, x1 = x4 and x2 = x3. The setting of the recording paper and the storage of the received image information in the line buffer are all performed by the center distribution. FIG. 6B is a diagram showing a storage position of data (indicated by oblique lines) in the line buffer corresponding to each size when the reception width = the recording width, and FIG. FIG. 11 is a diagram illustrating storage positions of data (also indicated by oblique lines) in a line buffer corresponding to each size in a case where reception width <recording width.

When recording is performed in the data storage state shown in FIG. 6B, if the reception width is smaller than the recording width, the state is as shown in FIG. In the present embodiment, when the reception width <the recording width, the storage position of the data stored in the line buffer is shifted to obtain the recording state as shown in FIG. FIG. 1 shows an operation flowchart of the present embodiment. FIG. 1 shows an operation flow when performing thermal recording. Hereinafter, an outline of the operation will be described. When the recording operation is started, first, in step 101, the line buffer is initialized. In step 102, the reception width is detected, and in step 103, the reception width detected in step 102 is compared with the maximum recording width. If the reception width is smaller than the recording width, then, at step 104, it is checked whether or not a recording sheet having the same width as the reception width is set. If the receiving width is not smaller than the recording width in step 103 (NO), and if the recording paper having the same width as the receiving width is set in step 104, the recording paper having the same width as the receiving width is selected in step 111. Then, the data is transferred to the thermal output buffer in the pattern shown in FIG. 6C according to the reception width (step 112).

If it is determined in the step 104 that no recording paper having the same width as the receiving width is set, in a step 105, an optimum recording paper is selected from the set recording papers. Here, for example, if the receiving width is B4, an A3 size (width) recording paper is selected. If the receiving width is A4, a B4 size (width) recording paper is selected. Will do. Next, in step 106, the shift amount of the storage position of the data stored in the line buffer is detected based on the equation (the width of the recording paper selected above−the receiving width) / 2.
Then, based on the result, the shift of the data storage position in the line buffer is executed. Here, first, FIG.
In the pattern shown in (c), from the top, x2, x1, x1 + x
Will be shifted by two. The data thus obtained is transferred to the thermal output buffer as the data of the recording paper width selected above (step 108). Thereafter, the processing shifts to the processing of the next line. In this case, the setting method of the start address of the next line is to give a recording size at the start of each line,
Here, in the case of the A3 size, the head address + the x1 in the case of the B4 size, and the head address + the x1 + x2 in the case of the A4 size.

According to the above-described embodiment, it is possible to select a recording sheet having an optimum size while being set in the apparatus, and to perform recording in the form shown in FIG. A terminal device that can easily handle received image information can be realized. In the above description, the case of performing thermal recording has been described as an example, but the case of performing laser recording is substantially the same.
In the case of performing laser recording, recording is started when one page of data is stored in the page memory. There are several methods for using the page memory described above. One example is shown in FIGS.
Shown in The example shown in FIG. 8 has an advantage that addressing can be performed regardless of the size, but has a disadvantage that loss occurs in a small size. FIG.
In the example shown in (1), the loss at the small size as described above is eliminated, but there is a disadvantage that the addressing is somewhat complicated. Next, an embodiment will be described in which the same effect as above is obtained by processing on the transmission side. FIG. 10 illustrates a main part of a facsimile transmission / reception procedure according to the present embodiment. In the present embodiment, the document size (w1) is determined on the transmitting side when the document is read by the reading unit, and held.

Then, DIS (or NS) from the receiving side
F1) Before detecting the receivable width (w2) included in F) and sending out DCS (or NSS), (1) When w1> w2: w1 = w after reduction on the transmitting side
By notifying as 2 or transmitting only the w2 part,
Notify as w1 = w2. (2) When w1 = w2: Notify as w1 without any problem. (3) When w1 <w2: Conventionally, this was notified as w1, and the result is as shown in FIG. 2. Here, data for w1 is packed from the head of each line, and then w3 = w2-w1. The margin is reduced, and the transmission width is notified as w2. This makes it possible to perform recording as shown in FIG. At this time, by appropriately inserting a black bit into the above-mentioned w3, an output as shown in the present invention of FIG. 11 is obtained, and operations such as cutting during filing become easy. Here, even if extra white continuations are inserted, the processing time hardly changes due to compression, so that the overhead of the transmission time is extremely small.

Next, when the size of the received image information and the size of the recording paper are different from each other, a page memory is used to effectively use the recording paper.
An embodiment in which degree rotation recording is performed will be described. The transfer of the received data from the line buffer to the page memory to the line buffer in the path of the LD (laser diode) output buffer to the page memory shown in FIG. In the case of a laser recording apparatus having a page memory, the output from the page memory is performed when the page memory is full, as described above, so that the operation of changing the reading direction from the page memory can be performed. is there. This is the principle of the present embodiment. That is, image data substantially equal to the image of the output image is temporarily stored in the page memory. At this time, when recording a size one rank lower than the maximum recording size (for example, the former is A3 size, and the latter is A4 size), A4T = A3
Since it is Y, a recording example by the conventional method (see FIG. 12A)
Can be output at the same magnification even if rotated by 90 degrees
(See FIG. 12 (b)).

Hereinafter, this will be described in detail. In order to effectively pack data in the page memory, the method shown in FIG. 9 is advantageous among the above-described methods of using the page buffer (see FIGS. 8 and 9). Hereinafter, the description will be continued according to this usage. When data accumulation in the page memory is started, if the data length of one line and the empty address at the head thereof are known, a head address (ST) buffer (see FIG. 9) for each line can be created. FIG. 13A schematically shows a state where A4 size data is stored in the page memory in the present embodiment. Normally (conventional), the size (width) is notified to the above-mentioned LD output buffer when one page is accumulated, thereby notifying the number of transfer data of one line. Next, data is DMA-transferred line by line from the contents of the head address buffer of each line. But here,
As described above, A4 size image information is recorded by rotating it by 90 degrees on A3 size recording paper. For this purpose, first, based on the contents of the page memory shown in FIG. As shown in FIG. 13B, the head data of each line is stored in the 90-degree rotation buffer.

After that, the next data of the head data of each line, the data of the next position, and so on are displaced (indicated by "Y"), and the data is sequentially rotated by 90 degrees. The head data of each line is stored in the buffer. In addition, the contents of the above-described 90-degree rotation buffer are sequentially
DMA transfer is performed to the LD output buffer (see FIG. 13C). That is, after the next line, the L1ST + Y data is set at the head of the 90-degree rotation buffer, the L2ST + Y data is set at the next position of the 90-degree rotation buffer, and so on. Here, if Y is sequentially incremented and repeated until Y = A4Y, 90
An output rotated by degrees is obtained. Depending on the linear density,
The data number of both or one of the sub-scans may be compressed to 1/2 ⁿ . For example, 8 × 3.85 (STD) and 8 × 7.7
In the case of having (DTL), with the output rotated by 90 degrees, the former has 2/1 main scanning. In this case, as shown in FIG. 13D, the effect can be substantially eliminated by using each data twice.

Further, α on the right side of FIGS. 13 (b) to 13 (d) is for dealing with the variation in the received image information due to the processing of the partner reading unit, the transmission processing unit, and the like. If α is −, the data corresponding to the margin is discarded. This is because it is necessary to notify the size at the time of DMA transfer of data from the page memory to the LD output buffer or from the 90-degree rotation buffer to the LD output buffer. Only when A4T of the data in the page memory has a value substantially equal to A3Y at the time of the DMA transfer, the above processing is performed and the data can be used. In the above-described determination, the maximum value (maxA4 length) and the minimum value (minA4 length) may be determined, and then minA4 length ≦ received A4 data length ≦ minA4 length. The maximum value (maxA4 length) and the minimum value (minA4 length) may be stored in a system RAM and made rewritable. The above-mentioned + α occurs when A4T <A3Y of the received data, and −α occurs when A4T <A3Y of the received data. The processing in this case may be as described above. FIG. 14 shows an operation flowchart of the above-described 90-degree rotation processing.

The process shown in FIG. 14 is started when one page of data is stored in the page memory. Here, as described above, an example is shown in which A4 size image information is rotated by 90 degrees and recorded on A3 size recording paper. In step 201, the reception width is detected, and in step 202,
The recording width is detected. As described above, when the recording paper size is A
3. If the received image information width is A4, in step 203,
The DMA transfer width is set to A3 for notification, and the aforementioned “Y” is initialized. Thereafter, in step 204, the linear density is determined. If it is DTL, the process proceeds to step 205, and if it is STD, the process proceeds to step 209. In step 205 (in the case of DTL), the data is stored in a 90-degree rotation buffer as shown in FIG. In FIG. 14, the symbol “90 ⁰ B” is 90
Degree rotation buffer. Step 209
In the case of STD, as shown in FIG. 13D, the same data is stored twice in the 90-degree rotation buffer. Y = 0
Is completed, the contents of the 90-degree rotation buffer are DMA-transferred to the LD output buffer (step 206). This is repeated until Y = A3Y (steps 204 to 208).

If the receiving width is not A4 size in step 201, and if the recording width is not A3 size in step 202, normal rotation is not performed and normal processing is performed (steps 210 to 218). . In the above embodiment, the case where the recording paper size is A3 and the received image information width is A4 has been described as an example. However, this method is applied to a rolled recording paper having the size of A3 width and the image information having the received width of A4. It is needless to say that the present invention is also effective when recording Also, as mentioned above,
If the recording paper size is A3 and the received image information width is A4,
If pages of the same condition are continuous, two pages can be output on one sheet of recording paper. Hereinafter, this will be described. FIG. 15 shows a schematic operation flowchart. As shown in steps 201 and 202 in FIG. 14, the conditions for 90-degree rotation are checked. If the conditions are satisfied, page n is stored in the page memory (step 301). Next, in step 302, the presence or absence of a mode change (EOM) is checked. If the mode is changed, the presence / absence of a change in recording width (step 303), the presence / absence of a change in line density (step 304), and the like are performed. If the line density is to be changed, the above-described page n is output by rotating one page by 90 degrees (step 308).

If there is no mode change in step 302, a post message (MPS) is sent in step 305.
Is checked, otherwise, the page is the last page, so only this page is rotated and output by 90 degrees (step 308). In step 305, if it is an MPS, wait for the next page (n + 1) to be stored in the page memory.
(Step 306) The page n and the page (n + 1) are rotated 90 degrees and output as the same page (Step 307). The same applies to the case where neither the recording width nor the linear density is changed in steps 303 and 304. Step 3
When the recording width is not changed in 03 and 304, but the line density is changed, processing corresponding to the line density is performed in the same manner as in steps 204 to 209 in FIG.
(In FIG. 15, the portion indicated by "A"). In this case, two types of 90-degree rotation buffers are used. Next, a case where the reduced document storage setting can be set on the receiving side will be described. In this case, for example, when page n is A4 size and page (n + 1) is B4 size, one of these two pages can be reduced and recorded and output on one page of A3 size recording paper.

The above-described example is effective when the user owns the cassettes of the respective sizes A4, B4 and A3 and runs out of the A4 size recording paper. First, the first page n is stored in the page memory in the same manner as in step 301 shown in FIG. Here, when there is recording paper of each size of B4 and A3 and there is also the next page (n + 1),
As described above, it is efficient to use A3 size recording paper. In the example shown in FIG. 15, when there is a mode change (EOM) between the next page, 1
Only the page is recorded and output. In this case, since there is a next page and it is a condition that can be reduced and output, the B4 size page (n + 1) is added to the A4 size page (n + 1) following the A4 size page n.
Reduce the size and store it in the page memory. This reduction is performed when decoding is performed by the DCR from the image memory and stored in the line buffer. On the page memory side, A4 size data is accumulated for two pages, and the subsequent processing is the same as the above-described processing. Next, a description will be given of an embodiment in which the above-described processing is applied to transmit the image information rotated by 90 degrees after confirming the maximum recordable size on the receiving side at the time of transmission.

It should be noted that, here, the fact that the transmission size and the data direction are rotated by 90 degrees can be notified between the transmitting and receiving terminals by a non-standard communication protocol. is necessary. FIG.
FIG. 3 is a diagram illustrating an outline of the present embodiment. FIG. 16 shows a situation where the other party can receive A3 size document and the transmitting side transmits an A4 size document rotated by 90 degrees. According to the present embodiment, when the size of the image information to be received and the size of the recording paper are different on the receiving side, the effect that the recording paper can be effectively used is obtained, and the communication time is shortened. There is also an effect that. When it is detected that the pages that can be transmitted by the transmission method shown in FIG. 16 are continuous with reference to the number of pages and the mode of the document stored in the memory, a plurality of originals are transmitted together. Thereby, the efficiency can be further improved. In the above embodiment,
Although the case where the recording paper is cut paper has been described, the same processing as in the present embodiment can be performed even when the recording paper is roll paper, and the above processing can be appropriately used depending on the type of recording paper. It is possible.

Recently, a terminal device having an AI learning function has been used. At that time, the condition of the recording paper of the other party (whether roll paper or cut paper, the size is
Etc.), the present invention can be easily used. Each of the above embodiments is merely an example of the present invention, and it is needless to say that the present invention should not be limited to these.

[0022]

As described above in detail, according to the present invention, when the size of the received image information is different from the size of the recording paper, the recorded received image information can be easily handled. This has a remarkable effect of realizing a terminal device that makes effective use of recording paper.
