The detection of the recording paper 51 by the recording paper front edge detection sensor 18, the recording paper discharge detection sensor 19 and the recording paper presence sensor 20 will be described with reference to FIG. First, the presence / absence of the recording paper 51 in the recording paper cassette 59 is detected by the recording paper presence / absence sensor 20. Then, the paper feed roller 6
While the recording paper 51 fed in 1 is sent to the platen 53, the leading end of the recording paper is detected by the recording paper leading edge detection sensor 18, and the recording paper 51 is further fed to the platen 53 side, and the trailing end thereof is This is further detected when passing the front of the recording paper leading edge detection sensor 18, and the facsimile apparatus 10 of the present embodiment calculates the length of the recording paper 51 based on the detection of the leading edge and the trailing edge of the recording paper 51. Is configured to. When printing is performed on the recording paper 51, the ribbon 55 is moved by the line print thermal head 22 placed at a position facing the platen 53 in synchronization with the feeding of the recording paper 51 by the platen 53. The heat-soluble ink is melted and transferred (printed) to the recording paper 51. At the time of this transfer, the ribbon 55 is fed at the conveyance speed of the recording paper 51 by rotating the ribbon roll 57. Then, when the printed recording paper 51 is conveyed to the position of the recording paper discharge detection sensor 19, the recording paper discharge detection sensor 19 causes the recording paper 51 to move.
Is detected to be properly fed, and the recording paper 51 is ejected by the paper ejection roller 63. A slide-type partition plate 59a is provided inside the recording paper cassette 59. When the recording paper cassette 59 is positioned at the rear end A of the recording paper cassette 59, a recording paper of a legal size of 356 mm, As shown in the figure, when it is positioned at the front end B, it can accommodate a recording sheet 51 of letter size 279 mm.

Next, a reception recording (printing) process by the facsimile apparatus 10 of this embodiment will be described. Prior to this description, first, a document (image information) sent from the facsimile machine on the other side will be described with reference to FIG. In the original 80, the print portion continues from the first line 80a to the line 80b, and then from the line 80b to the line 80c.
It is assumed that the blank portion continues until the line 80c and the printed portion continues to the line 80d again.

First, the overall processing of reception recording by the facsimile apparatus 10 of the present embodiment will be described with reference to the flowchart (main routine of reception recording) shown in FIG. When the image information (original 80) shown in FIG. 3 sent from the facsimile machine on the other side is received by the NCU 12, it is demodulated into a digital signal by the modem 14 and the CP is transmitted.
Added to U16. The CPU 16 determines the protocol, the communication speed, and the resolution in the communication control of step 1. Next, in the judgment step 2, the recording paper presence / absence sensor 20 judges whether or not the recording paper 51 is present in the recording paper cassette 59. If the recording paper 51 is not present (judgment step 2 is No), the recording paper is detected. On the other hand, if the recording paper 51 is present, the process proceeds to the paper feed control process in step 3, and the recording paper 51 is removed from the thermal head 22.
Transport to. This process will be described in detail later.

Next, in step 4, a process for decoding one line of the image information shown in FIG. 3 is performed. Then, the process proceeds to decision step 5, and it is determined whether or not the page end is detected. If the page end is not detected (decision step 5 is No), the process returns to step 4 and the decoding process for the next line is performed. To do. By repeating this process, the decoding of the image information shown in FIG. 3 is completed. When the determination step 5 is Yes after the image information decoding process is completed, the process proceeds to the recording control process of step 6 to record one page of the recording paper 51. This process will also be described in detail later.

When the recording of one page in step 6 is completed, the process proceeds to decision step 7, and it is determined whether there is data for the next page, that is, whether all the image information has been recorded,
If there is data for the next page (Yes at determination step 7), the process returns to step 6 to record the next page. Then, when the recording of all the image information is completed, the judgment step 7 becomes No, and the process proceeds to step 8 to exchange with the facsimile apparatus on the other side for communication end, and all processing is completed.

Next, regarding the "paper feed control" process for feeding the recording paper 51 in step 3 of the flow chart shown in FIG. 5, the flowchart shown in FIG. 6 and FIG. Will be described in detail with reference to. In this "paper feed control", first, in step 61,
The CPU 16 sends a command to the thermal head 2 shown in FIG.
Release 2 to the arrow C side. Then, the process proceeds to step 62, and the recording paper 51 is fed by one step (line). Next, in a judgment step 63, it is judged by the recording paper leading edge detecting sensor 18 whether or not the leading edge of the recording paper 51 can be detected.
When the leading edge of the recording paper 51 cannot be detected (No in the determination step 63), the process returns to step 62 and the recording paper 51 is further fed. When the leading edge of the recording paper 51 is detected by the recording paper leading edge detection sensor 18, the judgment step 63 returns Y.
It becomes es and the process proceeds to the next step 64. In step 64, the recording paper 51 is fed by an amount (predetermined amount) corresponding to the length from the recording paper leading edge detection sensor 18 to the platen 53. Then, in step 65, the thermal head 22 is nipped in the direction of arrow D in the figure.

Next, the "recording control" process for recording on the recording paper 51 in step 6 of the flow chart shown in FIG. 5 will be described with reference to FIGS. 7, 8, 9, 10 and 1.
This will be described in detail with reference to the flowchart shown in FIG. 1 and FIG. 2 showing the operation of conveying the recording paper 51. First, in the flowchart shown in FIG. 7 which is the main routine of the "recording control", in step 71, the recording paper length counter for measuring the recording paper length is cleared. Next, decision step 7
In step 2, it is confirmed whether or not there is data in the recording buffer.
Here, since the process is proceeding for the leading line 80a of the document 80 shown in FIG. 3, it is determined that there is data in the recording buffer, and the process proceeds to step 73 to start the recording of each line by the thermal head 22. First, in the judgment step 74, it is judged whether or not the line to be printed is the last line. However, since the leading line 80a of the document 80 is not the last line, the judgment step 74 becomes No and the process proceeds to the next judgment step 75. In the decision step 75, it is checked again whether or not there is data in the recording buffer. However, since there is data here, the decision step 75 becomes Yes and the process proceeds to the next decision step 76. In the judgment step 76, it is judged whether or not the recording is stopped, that is, whether or not the white line skip described later is being executed. Here, since the recording of the first line 80a of the original 80 is to be started, the judgment step 76 becomes No, and the process proceeds to step "1 line recording control" processing.

"1 line recording control" of this step 77
This will be described with reference to the flowcharts shown in FIGS. 8 and 9. In step 81 of the flowchart shown in FIG. 8 showing the "1-line recording control", the "recording basic control" for measuring the length of the recording paper and printing (recording) on the recording paper 51 is advanced. The "basic recording control" processing in step 81 will be described in detail with reference to the flowchart shown in FIG. First, in step 91, the CP
The U 16 feeds the recording paper 51 by one line (step) by giving a command to the motor driver 30 shown in FIG. 1 and giving a pulse to the recording paper feed motor 28. Next, in a determination step 92, the recording paper leading edge detection sensor 18 sets the recording paper 5
Judge whether 1 is output. Here, the recording paper 5
If 1 is output, the judgment step 92 returns Y.
When es is reached, the process proceeds to step 93, and the value of the recording paper length counter for measuring the length of the recording paper 51 is incremented by 1.

Next, in step 94, the CPU 16
Transfers the data in the print buffer to the thermal head 22 and gives a command to the strobe generating circuit 24 shown in FIG. 1 to perform printing (recording) on the one line. As a result, the "recording basic control" process for one line is completed, and the process shifts from the "recording basic control" process in step 81 shown in FIG.

In step 82 shown in FIG. 8, the data in the print buffer is checked. Here, it is determined whether one line in the determination step 83 is completely white, that is, whether the ribbon 55 has been thermally transferred to the recording paper 51. Since the leading line 80a of the original 80 has been recorded as described above, the judgment step 83 becomes No and the processing shifts to the step 89. In step 89, the value of the white counter that counts the number of lines that have not been printed due to white line skip is initialized, and as a result, "1 line recording control" shown in FIG. 8, that is, step 77 of the flowchart shown in FIG. The "1-line recording control" process ends.

When the "1-line recording control" process of step 77 of the flowchart shown in FIG. 7 is completed by the above-described series of processes, the determination step 74 is performed in order to process the next 1 line of the leading line 80a of the document 80. Then, the process goes through the judgment steps 74, 75, and 76 again to the "one-line recording control" of step 77. Then, the procedure again goes to the "basic recording control" in the first step 81 of the "1 line recording control" flowchart (FIG. 8).
In this "basic recording control" of step 81, step 93 is performed through steps 91 and 92 of the flowchart shown in FIG.
Then, the process advances to step S6 and further increments the value of the recording paper length counter for measuring the length of the recording paper 51 by one.

Next, in step 94, printing (recording) is performed on the one line. As a result, the "recording basic control" in step 81 (FIG. 8) for one line is performed.
Processing is completed, and the processing proceeds to the processing after step 82. By repeating the above processing for each line, recording is performed while feeding the recording paper 51, and at the same time, the value of the recording paper length counter is incremented in step 93 of the flowchart shown in FIG. Measure the length. The state of printing on the recording paper 51 is shown in FIG. Figure 4
(A) shows the first sheet of recording paper 51 on which recording is currently being performed.

Recording for each line on the recording paper 51 shown in FIG. 4A is repeated, and the rear end portion 51 of the recording paper 51 is repeated.
When a'passes in front of the recording paper leading edge detection sensor 18 (see FIG. 2), the determination at determination step 92 in the flowchart shown in FIG. 9 becomes NO, and the process proceeds to determination step 95. In the judgment step 95, it is judged whether or not the recording paper 51 is the first one. Here, since the recording paper 51 is the first sheet,
The determination step 95 becomes Yes and the process proceeds to step 96. In step 96, the value of the recording paper length counter incremented in step 93, that is, the recording paper leading edge detection sensor 18 causes the leading edge of the recording paper 51 (5 in FIG. 4A).
1a) is detected and then the trailing edge of the recording paper 51 (see FIG. 4A) is detected.
51 a ′) of the recording paper 51, the recording paper length data (the length of the recording paper 51) based on the value of the pulse (the number of pulses) given to the recording paper feed motor 28 for feeding the recording paper 51.
To get. Based on the acquired recording paper length data, the facsimile apparatus 10 of this embodiment performs page division processing as described later. When the processing of step 96 ends,
The process moves to step 94 to print on the recording paper 51 and the "recording basic control" for the line is completed.

When the "recording basic control" in step 81 of the flow chart shown in FIG. 8 is completed, the print buffer data is checked in step 82,
The "1-line recording control" is completed. As a result, the "1-line recording process" in step 77 of the flowchart shown in FIG. 7 is completed, and the process returns to the judgment step 74. When the recording of the final line 51a ′ of the recording paper 51 shown in FIG. 4A is completed in the judgment step 74, the judgment step 74 becomes Yes and the process shifts to the “discharge control” in step 79.

The process in the "discharge control" of step 79 will be described in detail with reference to the flowchart shown in FIG. In this "emission control", first, step 3
At 1, the CPU 16 sends a command to release the thermal head 22 shown in FIG. 2 to the arrow C side. Then, the process proceeds to step 32, and the recording paper 51 is fed by one step. Next, in a judgment step 33, it is judged whether or not the recording paper 51 is detected based on the output of the recording paper discharge detection sensor 19. When the recording paper 51 cannot be detected, the determination step 33 becomes Yes, and the process returns to step 32 and the recording paper 5
Send 1. When the recording paper 51 is detected by the recording paper discharge detection sensor 19, the determination step 33 becomes Yes and the process proceeds to the next step 34. In step 34, the recording paper 51 is fed from the paper discharge roller 63 shown in FIG.

By the above processing, printing on the first recording paper 51 shown in FIG. 4A is completed. This completes the "recording control" process of the flowchart shown in FIG.
From the "recording control" process in step 6 of the flowchart (main routine for receiving and recording) shown in FIG. In this judgment step 7, since there is the next page data, the judgment step 7 becomes Yes, the process returns to step 6 and the "recording control" for the second recording paper 51 shown in FIG. 4B is started. . First, in the flowchart shown in FIG. 7 showing the "recording control" in step 6, the recording paper length counter is cleared in step 71.
Next, in decision step 72, it is confirmed whether or not there is data in the recording buffer. Here, since the process for the line 80a ′ (the line corresponding to the line 51a ″ of the second recording paper 51 of FIG. 4B) on which the document 80 shown in FIG. 3 is printed is being advanced, If there is data in the recording buffer, the judgment step 72 becomes Yes and step 73
Go to. In step 73, the thermal head 22
Start recording line by line. Here, the judgment step 74 (the judgment step 74 is No), the judgment step 7
5 (Yes in the determination step 75) and determination step 7
After 6 (No in the determination step 76), the process proceeds to the one-line recording control process in step 77.

[1 line recording control] of this step 77
Will be described with reference to the flowcharts shown in FIGS. 8 and 9 again. Printing (recording) is performed in the "recording basic control" of step 81, which is the first step of the flowchart showing "1 line recording control" of this step 77.
Start processing. Reference is made to the flowchart shown in FIG. 9 showing the "recording basic control" processing in this step 81. First, in step 91, the CPU 16 feeds the recording paper 51 by one line (step) by giving a command to the motor driver 30 shown in FIG. 1 and giving a pulse to the recording paper feed motor 28. Next, in a judgment step 92, it is judged whether or not the recording paper leading edge detection sensor 18 outputs the existence of the recording paper 51. Here, since the recording paper 51 is present, the judgment step 92 becomes Yes, and the routine proceeds to step 93, where the value of the recording paper length counter is incremented by one.

Next, in step 94, the CPU 16
Prints (records) the one line. This completes the "recording basic control" processing for one line, and proceeds to the processing at step 82 in the flowchart shown in FIG.

In step 82, the data in the print buffer is checked. First, in the judgment step 83, it is judged whether or not the printing line is a blank part. However, since the line 80a 'of the printing part is being recorded, the judgment step 83 becomes No and the process is step 89.
Move to. In step 89, the value of the white counter is initialized, whereby the "1-line recording control" process of the flowchart shown in FIG. 8, that is, the "1-line recording control" process of step 77 of the flowchart shown in FIG. 7 is completed.

Step 77 of the flowchart shown in FIG.
When the "1 line recording control" process is completed, the process returns to the judgment step 74 and the same processes are repeated in order to process the next 1 line of the line 80a 'of the document 80 shown in FIG. Then, when the line to be processed reaches the line 80b (blank portion) of the document 80 shown in FIG. 3, the increment of the value of the white counter for counting the number of lines that have sent the blank portion is started. The description of this process will be continued with reference to the flowcharts shown in FIGS. 9 and 8.

When the processing for the line 80b of the original 80 is started, step 91 of the flowchart shown in FIG.
Then, the recording paper 51 is fed by one step, and the following judgment step 9
2 (Yes in the determination step 92), steps 93 and 94 are performed, the "recording basic control" processing (step 81 shown in FIG. 8) shown in FIG. 9 is completed, and the determination is made after the processing in step 82. In step 83, it is determined whether the line is for printing. Here, the determination step 83 becomes Yes and the process proceeds to the determination step 84. Judgment step 8
In step 4, it is determined whether the ribbon save process is effective. Here, the determination step 84 becomes Yes and the process proceeds to the next step 85. In step 85, the white counter for recording the number of blank lines continued is incremented by one. Then, in the next judgment step 86, it is judged whether or not the value of the white counter is larger than the value α set as the judgment value for stopping the recording paper 51 for ribbon save. Here, since the process for the line 80b is started, the determination step 86 is No. This completes the "1-line recording control" process of the flowchart shown in FIG.

Then, when the above-mentioned processing for the blank line is repeated while incrementing the value of the white counter by 1 in step 85, the value of the white counter becomes larger than the value α set as the judgment value. . As a result, the determination step 86 becomes Yes and the process proceeds to step 87. In step 87, the recording stop is instructed to stop the ribbon feeding to save the ribbon 55. Then, in step 88, the value of the white counter is initialized to 0, and the "1-line recording control" process of the flowchart shown in FIG. 8 ends.

Returning to the flow chart shown in FIG. 7, when the "one-line recording control process" in step 77 is completed, a judgment step 74, a judgment step 75, and a judgment step 76 are made to judge whether the recording is stopped. Here, the determination step 76 is Yes, and the process proceeds to the process of "control after recording stop" of step 78. This step 7
The "control after recording stop" process 8 will be described in detail with reference to the flowchart shown in FIG. For the sake of convenience, the two types of processing, that is, the case where the recording paper 51 is long and the case where the recording paper 51 is short, will be described separately. That is, long (legal size)
Since the recording paper 51 is used, the blank lines 80b to 80c of the original 80 shown in FIG. 3 are accommodated in the second recording paper 51 and the printing from the line 80c of the original 80 is performed on the second recording. Fig. 4 (b) shows the case of restarting on the paper 51.
On the other hand, short (letter size) recording paper 5
A case in which the blank lines 80b to 80c of the original 80 shown in FIG. 3 cannot be completely accommodated in the second recording paper 51 by using 1 is described as an example of FIG. 4C. .

[Case of FIG. 4B] First, the flowchart shown in FIG. 11 (control after recording stop)
In step 101, the data in the recording buffer is checked. Here, in the judgment step 102, it is judged whether or not the data of one line is the data which is not printed.
Here, since the data is not printed, the determination step 102 becomes Yes and the process proceeds to step 103. In step 103, the white counter value is incremented by 1. Then, in the next determination step 104, it is determined whether or not the recording paper 51 on which the recording is performed is the first page.
Here, since the second page is being processed, the determination step 104 is No, and the process proceeds to the determination step 106. In this determination step 106, the number of lines recorded on the recording paper 51 (recording paper counter value {the number of lines from the leading line 51a ″ of the recording paper 51 shown in FIG. 4B to the line 51b} + white counter Value) and the length of the recording paper 51 (recording paper length data measured at the time of recording on the first recording paper 51 (here, line 51a to line 51a ′ shown in FIG. 4A)). The number of pages is allocated based on this determination as will be described later.Since the processing of the line 51b of the recording paper 51 shown in FIG. The value + the value of the white counter does not exceed the recording paper length data, the determination step 106 is No, and the process of “control after recording stop” in the flowchart shown in FIG. 11 ends.

When the "post-recording stop control" process of the flow chart shown in FIG. 11 is repeated to reach the process for the line 80c which is the print portion of the document 80 shown in FIG. 3, the determination step 102 of the flow chart shown in FIG.
Is No, and the process proceeds to the determination step 108. In the judgment step 108, it is judged whether a page division flag described later is set. Here, since the page division flag is not set, the determination step 108 is No, the process proceeds to step 112 and recording is restarted, and
Recording (printing) on and after the line 51c of the recording paper 51 shown in (b) is advanced.

[Case of FIG. 4 (c)] Similar to the case of the long recording paper 51 shown in FIG. 4 (b), the flowchart shown in FIG. 11 (control after recording stop)
The determination of the determination step 106 is performed through the processing of steps 101, 102, 103, and 104. In this judgment step 106, the value of the recording paper counter + the value of the white counter exceeds the length of the recording paper 51 (recording paper length data, here, the short recording paper 51 is measured as the first sheet). Determine if Since the processing of the line 51b of the recording paper 51 shown in FIG. 4C has just started, the value of the recording paper counter + the value of the white counter does not exceed the recording paper length data, and the judgment step 106 is No. Then, the process of "control after recording stop" in the flowchart shown in FIG. 11 ends.

When the process of "control after recording stop" in the flow chart shown in FIG. 11 is repeated and the process for the line 51b 'which is the trailing end portion of the recording paper 51 shown in FIG. The value of the counter + the value of the white counter become equal to the length of the recording paper 51, the determination step 106 of the flowchart shown in FIG. 11 becomes Yes, and the process proceeds to step 107. In step 107, the page division flag is set, and the "post-recording stop control" processing of the flowchart shown in FIG. 11 ends. Next, the "control after recording stop" of the flow chart shown in FIG. 11 is advanced, and the line 80 which is the print portion of the document 80 shown in FIG.
When the process for c is performed, decision step 102
Is No, the process proceeds to the judgment step 108. In the judgment step 108, it is judged whether or not the page division flag is set. However, since the page division flag is set here, the judgment step 108 becomes Yes, and the processing shifts to the processing of step 109, as shown in FIG. The operation of ejecting the recording paper 51 shown in c) is performed (see the flowchart shown in FIG. 10). Next, the process proceeds to step 111, the page division flag, the recording paper length counter, and the white counter are cleared, and "control after recording stop" in the flowchart shown in FIG.
The process ends. As a result, the "recording control" in step 6 of the flowchart (reception recording main routine) shown in FIG. 5 is completed, the process returns to the "recording control" in step 6 through the judgment step 7, and the third recording paper 51 (not shown) The printing process for the document line 80c and subsequent lines shown in FIG.

If there is a blank portion during printing on the first sheet of recording paper 51, step 104 of the flowchart shown in FIG. 11 becomes Yes, and judgment step 105
Go to. In this judgment step 105, the number of lines recorded on the recording paper 51 (recording paper counter value + white counter value) is compared with the letter size. This is because it is not possible to discriminate whether the recording paper 51 is the letter size or the legal size when the first sheet is being recorded, and therefore the processing is performed assuming that the first sheet is the short letter size.

As described above, in the facsimile apparatus 10 of this embodiment, the length of the recording paper 51 required for page allocation for ribbon save is determined by the recording paper front end detection sensor 18 from the front end of the recording paper 51 and the rear end. The edge and the edge are detected and automatically calculated based on this. Therefore, the facsimile machine 1
Even if the recording paper 51 of different length is used for each call, the page can be automatically allocated and recording can be performed. Further, according to the facsimile apparatus 10 of the present embodiment, it is not necessary to provide the recording paper cassette 59 for each of the recording papers 51 having different lengths, and it becomes unnecessary for the user to specify the recording paper length. In addition,
In the above-described embodiment, an example is described in which the legal size and the letter size having the same width but different lengths are automatically discriminated from each other for recording, but the present invention is not limited to this, and the width and the length are not limited thereto. different. For example, it is possible to discriminate between A4 and B5 size recording sheets. Furthermore, A
Recording can be suitably performed not only on the recording paper 51 having a standard size such as 4, B5 or the like, but also on the recording paper 51 having an arbitrary length.

[0038]

As is apparent from the above description,
According to the facsimile apparatus of the present invention, recording sheets of different lengths accommodated in the same recording sheet cassette can be automatically discriminated. Therefore, it is necessary to provide recording sheet cassettes for recording sheets of different lengths, and the operator It is not necessary to specify the recording paper length by.
