Abstract

PURPOSE:To confirm automatically contracted picture information in an original size. CONSTITUTION:Received picture information L is stored in a memory means 2, and the length by one page is detected by a reception length detecting means 3. When the length is within a prescribed range, the length is supplied to a contraction rate calculating means 6, and meanwhile, cut paper is set as recording paper to a recording means 4. The length of the recording paper is detected by a recording paper length detecting means 5 and is supplied to a contraction ratio calculating means 6. Then, the contraction rate is calculated. Picture information in the memory means 2 is contracted based on the contraction ratio by a reducing means 7 and is printed out by the recording means 4. Picture information is left in the memory means 2 as it is, and the information is directly printed out by the recording means 4 when the contracted picture information is difficult to see, and even details can be confirmed in this case since picture information is not contracted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus capable of reducing received image information and recording it.

[0002]

2. Description of the Related Art In a facsimile apparatus using a standard cut sheet (A4 size, letter size, legal size, B4 size, etc.) as a recording sheet, the length of one page of image information L received as shown in FIG. When L1 is longer than the length K1 (recordable length) of the recording paper K, it is usual to deal with the following two methods. That is, the length L1 of the image information L
When is less than or equal to the threshold value C, the image information L is reduced and printed out on one recording sheet K as shown in FIG. In this case, the reduction ratio α is the length K1 of the recording paper K and the received image information L
Value divided by the length L1, that is, reduction rate α = K1 / L1
Becomes

When the length L1 of the image information L exceeds the threshold value C, it is divided into a plurality of pages and printed out on the recording paper K without being reduced as shown in FIG. As a result, it is possible to prevent the image information from being too small and difficult to see.

[0004]

By the way, when the original transmitted by the transmission source is very small, for example, when a design drawing is transmitted, and when this is longer than the length K1 of the recording paper K set on the receiving side. May be recorded in a reduced size. In this case, even if the degree of reduction is not so great, the original fine image information is further reduced, which often makes it difficult to see.

At this time, it is troublesome because it is necessary to contact the transmitting side to enlarge the original and send it, or to turn off the automatic reduction function of the facsimile apparatus to send the original. In addition, communication costs and recording paper are wasted.

Therefore, the present invention has solved the above-mentioned problems. When image information that is automatically reduced is received, it is reduced and recorded, and then the image information is not reduced. A facsimile device capable of recording is proposed.

[0007]

In order to solve the above problems, in the present invention, a receiving means for receiving image information, a memory means for storing the image information, and a length of one page of the image information are detected. Reception length detection means, recording means for recording image information on a cut sheet, cut sheet length detection means for detecting the length of the cut sheet, image information by comparing the length of the cut sheet and the length of the image information A reduction ratio calculating means for calculating the reduction ratio of, and a reduction means for reducing the image information at the reduction ratio, and when the image information is longer than the cut sheet, after reducing and recording the image information,
The feature is that the image information can be recorded without being reduced.

[0008]

In FIG. 1, the image information L received by the receiving means 1
(FIG. 2) is stored in the memory means 2. The length L1 of one page of the image information L is detected by the reception length detecting means 3. In this example, the length L1 (= number of lines / resolution) is calculated from the number of lines and the resolution of one page written in the file control table (FIG. 4) created at the time of reception.
When the length L1 is between the threshold A and the threshold C (A
For <L1 ≦ C), this length L1 is supplied to the reduction ratio calculating means 6.

On the other hand, a cut sheet is set as the recording sheet K on the recording means 4, and the length K1 of the recording sheet K is detected by the recording sheet length detecting means 5 and supplied to the reduction ratio calculating means 6. Here, the length L1 of the received image information L and the length K of the recording paper K
The reduction ratio α (= K1 / L1) is calculated by dividing by 1.

Then, the image information L in the memory means 2 is reduced by the reducing means 7 on the basis of the reduction rate α, which is supplied to the recording means 4 and printed out on one cut sheet. Here, when the length L1 of the received image information L exceeds the threshold B (B <L1 ≦ C), the memory means 2 is used even after reduced printing.
If the image information L remains in the image information and the image information after reduction is difficult to see, for example, the image information L in the memory means 2 is directly supplied to the recording means 4 and printed out according to the instruction of the operator. In this case, since the image information L is not reduced, it is possible to confirm even a small portion.

If the length L1 of the received image information L is shorter than the threshold value A, it is printed out without being reduced,
When the length L1 exceeds the threshold value C, it is divided into a plurality of pages and printed out without being reduced.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a facsimile apparatus according to the present invention will be described in detail with reference to the drawings.

FIG. 1 shows functional blocks of a facsimile apparatus according to the present invention. In the figure, 1 is a receiving means,
Connected to the communication line and receive the image information transmitted from the other party. Reference numeral 2 is a memory means for storing the received image information. Reference numeral 3 is a reception length detecting means for detecting the length of one page of the image information stored in the memory means 2. A recording unit 4 prints out the image information in the memory unit 2 on a cut sheet. Various types of cut paper can be set.

Reference numeral 5 is a recording paper length detecting means, and the recording means 4
Detect the length of the cut paper set in. Reference numeral 6 denotes a reduction rate calculating means, which calculates a reduction rate α for reducing the length of the received image information within a predetermined range as described later. A reduction unit 7 reduces the image information in the memory unit 2 on the basis of the reduction rate α calculated by the reduction rate calculation unit 6. The image information reduced here is supplied to the recording means 4 and recorded on a cut sheet.

The criteria for printing out the received image information will be described with reference to FIG. Here, the length L1 of the received image information L as shown in FIG.
Are compared with three thresholds A, B, and C. The threshold value A is the same as the length K1 of the recording sheet K, and is a threshold value for discriminating whether the image information L is reduced or not reduced, and the threshold value B is left after the reduced printing and the image information L is left in the memory means 2 or The threshold value C for discriminating whether or not to leave the image data is a threshold value for discriminating whether the image information L is reduced or divided and printed without reduction.

Then, as shown in FIG. 2B, when the length L1 of the received image information L is less than or equal to the threshold A (L1≤A),
The image information L is printed out on the recording paper K without being reduced and is erased from the memory means 2. When the length L1 of the image information L exceeds the threshold A and is equal to or less than the threshold B (A <L1 ≦
In B), the image information L is reduced at a reduction rate α and printed out. Then, the image information L is erased from the memory means 2.

When the length L1 of the image information L exceeds the threshold value B and is equal to or less than the threshold value C (B <L1 ≦ C), the image information L is reduced at the reduction rate α and printed out, and thereafter the image information L is reduced. L
Are left in the memory means 2. When the length L1 of the image information L exceeds the threshold value C (C <L1), the image information L is not reduced but is divided and printed out on a plurality of recording sheets K. In this case, the image information L is stored in the memory means 2 after printing.
Erased from.

FIG. 3 shows the configuration of this facsimile apparatus. In the figure, 11 is a CPU that manages transmission / reception control,
Reference numeral 12 is a ROM that stores various control programs such as a transmission / reception program, and 13 is a RAM that stores image information to be transmitted. The image information read by the image reading unit 14 is stored in the RAM 13 via the interface 15 or is directly supplied to the modem and the network control circuit (NCU) 16 functioning as a transmitting / receiving unit. The image information input from the communication line is stored in the file memory 23 via the modem and the NCU 16 and is decoded and reduced or the page memory 2 as it is.
4 is supplied to the recording unit 18 which functions as a printer, and the contents thereof are recorded.

The telephone number of the transmission destination is displayed by being supplied to the display unit 20 through the interface 19. The operation unit 21 is provided with a plurality of keys (not shown), and when these keys are operated, the contents thereof are taken into the CPU 11 via the interface 22. Further, the facsimile apparatus is provided with the above-mentioned reception length detecting means 3, recording paper length detecting means 5, reduction ratio calculating means 6, and reduction means 7.

When the facsimile machine receives the image information L, it is stored in the file memory 23 and a reception file is created for each communication. The image information L is used for detecting the number of error lines and the length L for one page.
Decoded to detect a 1. When the image information L for one page is received, a file control table as shown in FIG. 4 is created. Information such as the received file name, the received time, the encoding method, the resolution, the number of lines of the page, the storage address of the received file, the file size, and the print flag are written in this file control table. In the print flag field, “1” indicating unprinted is initially set. The file control table is created for the second and subsequent pages by the same method.

5 and 6 are flow charts showing the procedure of the printout processing 30 of the image information L stored in the received file. For example, when the print button is pressed, it is determined whether or not there is a received file by referring to the file control table (FIG. 4) (step 31), and if it is determined that there is no received file, the printout process 30 ends. If it is determined that there is a received file, then it is determined whether the received file has not been printed, that is, whether the print flag is "1" (step 32).

If the print flag is judged to be "1", then the length L1 of the received image information L is calculated from the resolution and the number of lines (step 33). For example, if the resolution is 3.85 lines / mm and the number of lines is 770 lines, the length L1 of this page is L1 = 770 / 3.85 =
It becomes 200 (mm). Next, the length L1 and the threshold A are compared (step 34), and if the length L1 exceeds the threshold A, then this length L1 is compared with the threshold C (step 35).

If it is determined that the length L1 does not exceed the threshold value C, the image information L is read from the fill memory 23 (step 36) as shown in FIG. (Step 37). Subsequently, the reconstructed image information L is reduced at the reduction rate α (step 38) and written in the page memory 24 (step 39). Next, it is judged whether or not it is the page end (step 40). If it is not the page end, the next line is read from the file memory 23 in step 36, and the decoding and writing to the page memory are performed by the same processing as described above. Is performed.

If the page end is determined in step 40, the image information in the page memory 24 is printed out (step 41), and the received image information length L1 is compared with the threshold value B (step 41). Step 42). If the image information length L1 exceeds the threshold value B, the print flag of the file control table is rewritten to "2" (step 43). This printout process 3
0 ends. If it is determined in step 42 that the image information length L1 is less than or equal to the threshold value B, the received file is erased (step 44), whereby the printout process 30 is completed. That is, in this case, since the degree of reduction is small, it is determined that reprinting in the original size is not necessary as described later, and the received file is deleted.

If it is determined in step 32 that the received file is not unprinted, that is, the print flag is not "1", then it is determined whether or not a reprint request is made next.
That is, it is determined whether the print flag is "3" (step 45). If it is determined that the request is not a reprint request, that is, if the print flag is "2", the printout process 30 ends.

When it is determined in step 45 that the request is a reprint request, in step 34 that the image information length L1 is less than or equal to the threshold value A, and when the image information length L1 exceeds the threshold value C. If it is determined that the image information L exists, then the image information L is read from the file memory 23 (step 46). It is then decrypted (step 47) and subsequently written to page memory 24 (step 48). Next, it is determined whether or not the page is over (step 49). If not, then it is determined whether or not the page memory 24 is full (step 50).

If it is determined that the page memory is not full, the next line is read from the final memory 23 in step 46, and decoding and writing to the page memory are performed in the same procedure as described above. Done. Step 5
When it is determined that the page memory 24 is full in 0, the image information in the page memory 24 is printed out next, and in step 46, the image information L1 is read from the file memory 23. Processing similar to is performed.

If it is determined in step 49 that the page end is reached, the image information in the page memory 24 is printed out next, and in step 44, the received file in which the image information is stored is erased. The printout process 30 ends. Printout process 3 described above
When all 0s are completed, only the received file with the print flag “2” and its file information are left in the file memory 23 and the file control table.

The received file left in the file memory 23 even after being automatically reduced and printed out in this way can be printed out without being reduced according to the instruction of the operator. .. FIG. 7 is a flowchart showing the procedure of the reprint-out processing 60. For example, if the operator presses the reprint out button,
It is judged whether or not there is a received file (step 6)
1). If there is no received file, then the display of no file is performed (step 62), and this reprintout processing 60 ends.

If it is determined in step 61 that there is a received file, the process waits until the next received file name is input (step 63), and then there is the input file name by referring to the file control table. It is determined whether or not (step 64). If there is this, then the print flag of the file control table is rewritten to "3" (step 65), and then the image information L in the received file is printed out at the same size (step 66). The printout process 60 ends. If it is determined that the file name input in step 64 does not exist, then it is displayed that there is an input error (step 6).
7) This completes the reprinting process 60.

FIG. 8 is a flow chart showing the procedure of the remaining capacity display processing 70 of the file memory 23. First, the remaining capacity of the file memory 23 is a predetermined amount, 64 KB in this example.
It is determined whether the number is smaller than (byte) (step 71). If it is determined that the remaining capacity is 64 KB or more, it is then displayed that the file memory 23 has a free space (step 72), and the remaining capacity display processing 70 ends.

If it is determined in step 71 that the remaining capacity of the file memory 23 is less than 64 KB, then it is determined by referring to the file control table whether or not there is a received file whose print flag is "2" (step). 7
3). If it is determined that this is not the case, then it is displayed that the file memory 23 is full (step 7).
4) This completes the remaining capacity display processing 70.

If it is determined in step 73 that there is a received file whose print flag is "2", then the oldest received file among the received files is deleted (step 75), and then step 71. Then, it is determined whether the remaining capacity of the file memory 23 is less than 64 KB, and the same processing as described above is performed thereafter. In other words, this makes it possible to prevent the file memory 23 from becoming full because the received file that has been once reduced and printed out is left indefinitely.
