Description

【００１６】
表１に示すように、用紙後端が搬送センサを通過してから一定時間経過後に、用紙先端は書き込み開始位置に到達する。認識している用紙サイズと実際の用紙サイズが一致した場合は、そのまま通常どおり印字を行う（ステップＳ１０４；ＹＥＳ、ステップＳ１０７）。サイズ不一致だった場合は（ステップＳ１０４；ＮＯ）、回転出力可能かどうか判断し（ステップＳ１０５）、可能な場合は（ステップＳ１０５；ＹＥＳ）、回転処理を施した後印字動作を開始する（ステップＳ１０６，Ｓ１０７）。一方、回転処理が不可の場合はサイズエラーとして処理を終了する（ステップＳ１０５；ＮＯ、ステップＳ１０９）。そして、印字動作が正常に終了し、次ページがあればステップＳ１０２に戻って繰り返し（ステップＳ１１０；ＹＥＳ）、次ページがなければ処理を終了する（ステップＳ１１０；ＮＯ）。ただし、本来回転出力しようとして給紙したが、サイズ不一致となり、非回転出力ならば可と判断し、非回転で出力するケースもあり得る。実際の用紙サイズが、定型サイズではない（不定型サイズ）と判定された場合は無条件にサイズエラーとする。
【００１７】
このように、サイズ不一致が発生しても、印字を続けるので、用紙をセット（またはサイズ設定）する手間がかからない。また、メモリ代行受信とならないので、即時性で有利、かつメモリフルによる通信エラーや受信拒否を回避できる。
【００１８】
ここで、以下の表２に、認識している用紙サイズと、実際の用紙サイズが異なった場合の判定を示す。なお、表中、○：通常出力、回：回転出力、×：エラーを表す。
【００１９】
【表２】

【００２０】
次に、上述した直接受信時の印字動作において、給紙カセットの出口（搬送センサの位置）から、レジストセンサの位置までの距離が、給紙した用紙の長さよりも短い場合、書き込み開始した時点で、用紙の後端が搬送センサを抜けていないので、サイズ不一致かどうか判定できない。この場合、用紙の後端が搬送センサを抜けた時点で、サイズ判定を行い、サイズが一致していれば、現在出力中の用紙を正常終了と判断する。サイズ不一致だった場合には、異常終了と判断し、用紙排紙後、再出力を試みる。再出力時は、サイズ測定の結果に従い、回転出力可能ならば再出力を行うし、不可ならばサイズエラーとして、代行受信待機とするか、サイズの再設定を待つ。
【００２１】
このような動作について当該動作フローを示す図３に従って以下に説明すると、先ずプロッタが動作可能であって、直接受信動作において、給紙動作を開始し、更に印字動作も開始する（ステップＳ２０１；ＹＥＳ、ステップＳ２０２〜Ｓ２０４）。そして、用紙サイズが一致するか否かを判断し、一致していれば印字動作を正常として終了する（ステップＳ２０５；ＹＥＳ、ステップＳ２１１）が、一致しなければ印字動作が異常として終了する（ステップＳ２０５；ＮＯ、ステップＳ２０６）。そして、異常終了後、回転出力可能かどうか判断し（ステップＳ２０７）、可能な場合は（ステップＳ２０７；ＹＥＳ）再度給紙を開始し（ステップＳ２０８）、給紙した用紙に回転処理を施した後（ステップＳ２０９）、印字動作を開始する（ステップＳ２１０）。一方、回転処理が不可の場合はサイズエラーとして処理を終了する（ステップＳ２０７；ＮＯ、ステップＳ２１２）。そして、印字動作が正常に終了し、次ページがあればステップＳ２０２に戻って繰り返し（ステップＳ２１１、ステップＳ２１３；ＹＥＳ）、次ページがなければ処理を終了する（ステップＳ２１３；ＮＯ）。
【００２２】
このように、メカレイアウト、つまり搬送センサから書き込み開始位置までの距離による制約を受けないので、より小型の装置にも対応可能となる。
【００２３】
次に、上述した直接受信時の印字動作において、サイズ不一致と判定された場合、縮小印字可能かどうか判定する。縮小すれば印字可能な場合は、縮小して出力し、不可の場合（不定型サイズの場合）は、サイズエラーとする。なお、変倍率は、主走査、副走査それぞれについて計算し、値の小さい方を採用する。認識している用紙サイズよりも長さ、幅の両方とも実際の用紙サイズのほうが大きい場合は等倍で出力する。
【００２４】
次に、以下の表３に、認識している用紙サイズと、実際の用紙サイズが異なった場合の、変倍率（％）を示す。
【００２５】
【表３】

【００２６】
上記変倍率は、サイズ不一致と判定されたときに、認識している用紙サイズと、実際の用紙サイズを比較して変倍率を決定しているが、画データの主走査、副走査と、実際の用紙サイズの長さ、幅を比較して変倍率を決定すれば、より最適な変倍率を得ることができる。例えば、Ｂ５原稿を受信し、認識している用紙サイズがＡ４横、実際の用紙がＢ５横だった場合、上記変倍率に従うと、８６．５％に縮小して印字することになるが、画データの主走査、副走査に基づいて変倍率を算出すれば、１００％（等倍）で印字される。
【００２７】
このような動作について当該動作フローを示す図４に従って以下に説明すると、先ずプロッタが動作可能であって、直接受信動作において、給紙動作を開始する（ステップＳ３０１；ＹＥＳ、ステップＳ３０２，Ｓ３０３）。そして、用紙サイズが一致するか否かを判断し、一致していれば印字動作を正常として終了する（ステップＳ３０４；ＹＥＳ、ステップＳ３０７，Ｓ３０８）。一方、一致しなければ実際の用紙サイズは縮小出力可能か否かを判断する（ステップＳ３０５）。そして、縮小出力が可能な場合は（ステップＳ３０５；ＹＥＳ）、縮小処理を施した後（ステップＳ３０６）、印字動作を開始する（ステップＳ３０７）。一方、縮小処理が不可の場合はサイズエラーとして処理を終了する（ステップＳ３０５；ＮＯ、ステップＳ３０９）。そして、印字動作が正常に終了し、次ページがあればステップＳ３０２に戻って繰り返し（ステップＳ３０８、ステップＳ３１０；ＹＥＳ）、次ページがなければ処理を終了する（ステップＳ３１０；ＮＯ）。
【００２８】
このように、サイズ不一致が発生しても、印字を続けるので、用紙をセット（またはサイズ設定）する手間がかからず、メモリ代行受信とならないので即時性で有利であり、かつメモリフルによる通信エラーや受信拒否を回避できる。
【００２９】
ここで、上述した直接受信時の印字動作において、給紙カセットの出口（搬送センサの位置）から、レジストセンサの位置までの距離が、給紙した用紙の長さよりも短い場合、書き込み開始した時点で、用紙の後端が搬送センサを抜けていないので、サイズ不一致かどうか判定できない。この場合、用紙の後端が搬送センサを抜けた時点で、サイズ判定を行い、サイズが一致していれば、現在出力中の用紙を正常終了と判断する。サイズ不一致だった場合には、異常終了と判断し、用紙排紙後、再出力を試みる。再出力時は、サイズ測定の結果に従い、縮小出力（等倍含む）可能ならば再出力を行うし、不可ならば（不定型サイズの場合）サイズエラーとして、代行受信待機とするか、サイズの再設定を待つ。
【００３０】
このような動作について当該動作フローを示す図５に従って以下に説明すると、先ずプロッタが動作可能であって、直接受信動作において、給紙動作を開始し、更に印字動作も開始する（ステップＳ４０１；ＹＥＳ、ステップＳ４０２〜Ｓ４０４）。そして、用紙サイズが一致するか否かを判断し、一致していれば印字動作を正常として終了する（ステップＳ４０５；ＹＥＳ、ステップＳ４１１）が、一致しなければ印字動作が異常として終了する（ステップＳ４０５；ＮＯ、ステップＳ４０６）。そして、異常終了後、縮小出力可能かどうか判断し（ステップＳ４０７）、可能な場合は（ステップＳ４０７；ＹＥＳ）再度給紙を開始し（ステップＳ４０８）、給紙した用紙に縮小処理を施した後（ステップＳ４０９）、印字動作を開始する（ステップＳ４１０）。一方、縮小処理が不可の場合はサイズエラーとして処理を終了する（ステップＳ４０７；ＮＯ、ステップＳ４１２）。そして、印字動作が正常に終了し、次ページがあればステップＳ４０２に戻って繰り返し（ステップＳ４１１、ステップＳ４１３；ＹＥＳ）、次ページがなければ処理を終了する（ステップＳ４１３；ＮＯ）。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a facsimile apparatus, and more particularly, to a process when a recording paper size set in the apparatus is different from a recording paper size recognized by the apparatus.
[0002]
[Prior art]
If the recording paper size set in the facsimile machine is different from the recording paper size recognized by the facsimile machine, the facsimile machine at the time of output of the received image data selects the paper based on the recognized recording paper size. If the width of the actual paper size is smaller than the width of the recognized paper size, for example, if the actual size is A4 vertical and the recognized size is B4 vertical, the left and right edges of the image data are missing. Is printed. Alternatively, if the actual paper size length is shorter than the recognized paper size length, the trailing end of the image data is missing and printed.
[0003]
In order to solve these problems, Japanese Patent Application Laid-Open No. 9-249338 and Japanese Patent Application Laid-Open No. 11-275280 disclose proposals for detecting a size error, displaying an error message, and switching to memory alternate reception. Have been.
[0004]
[Problems to be solved by the invention]
However, in any of the above-described conventional examples, after the size error is detected, the sheet cannot be fed from the sheet feeding stage. Therefore, the subsequent reception must be performed by the memory reception, and there is a risk that the memory becomes over and the reception becomes impossible. . When a size error is detected, switching to alternate reception is performed. However, if the received image data width is too large to print with the paper size at hand, that is, if there is only A4 size paper at hand, the If the image data of A3 width is received by setting the A3 vertical size due to a mistake, printing cannot be performed until a sheet of an appropriate size is obtained, so that the immediacy is significantly reduced.
[0005]
SUMMARY OF THE INVENTION The present invention has been made to solve these problems, and an object of the present invention is to provide a facsimile apparatus which can always receive signals without memory over and has high immediacy.
[0006]
[Means for Solving the Problems]
In order to solve the above problem, the present invention measures the length and width of recording paper fed from a paper feeding unit capable of continuously printing on fixed-size recording paper, and recognizes the length and width on the device side. This is a control method for a facsimile apparatus capable of detecting a size error different from the recording paper size that is currently set. If the size mismatch is detected before recording the received image data, the size of the recording paper is predicted from the measured length and width of the recording paper. If the predicted recording paper size is a recording paper size that does not impair the received image data if the rotation output is performed, the rotation output is performed without stopping the printing operation. Therefore, it is possible to provide a facsimile apparatus which can always receive data without over-memory and has high immediacy.
[0007]
If a size mismatch is detected during the recording of the received image data, the size of the recording paper is predicted from the measured length and width of the recording paper. Then, if the predicted recording paper size is a recording paper size that does not impair received image data if rotational output is performed, the recording paper being recorded is ejected, and then the same image data is re-outputted by rotational output. Therefore, there is no restriction due to the mechanical layout, and a smaller device can be accommodated.
[0008]
Further, when the size mismatch is detected before the recording of the received image data, the recording paper size is predicted from the measured length and width of the recording paper. If the predicted recording paper size is a recording paper size that does not impair received image data if the reduced printing is performed, the reduced printing is performed without stopping the printing operation. Therefore, it is always receivable and has high immediacy.
[0009]
If the size mismatch is detected before recording the received image data, the size of the recording paper is predicted from the measured length and width of the recording paper. Then, if the predicted recording paper size is a recording paper size that does not impair received image data if reduced printing is performed, the recording paper being recorded is discharged, and then the same image data is re-output with reduced output. Therefore, there is no restriction due to the mechanical layout, and a smaller device can be accommodated.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
According to the control method of the facsimile apparatus of the present invention, when a size mismatch is detected before recording of received image data, the recording paper size is predicted from the measured recording paper length and width. If the predicted recording paper size is a recording paper size that does not impair the received image data if the rotation output is performed, the rotation output is performed without stopping the printing operation.
[0011]
【Example】
FIG. 1 is a block diagram showing a configuration of a facsimile apparatus according to one embodiment of the present invention. In the figure, a facsimile apparatus 10 of the present embodiment includes a CPU 11, a ROM 12, a RAM 13, a line buffer 14, a SAF 15, a page memory 16, an SCU 17 for controlling a scanner 18, a PCU 19 for controlling a plotter 20, an operation port 21, a DMAC 22, a DCR 23, It comprises a modem 24 connected to the NCU 25, and each component is connected to an internal bus 26, respectively. The CPU 11 is an arithmetic processing LSI that controls the facsimile machine 10. The ROM 12 stores a program for operating the CPU 11. The RAM 13 is a memory for storing data necessary for controlling the facsimile machine 10, and is divided into a volatile memory section and a nonvolatile memory section. The line buffer 14 is a memory for sequentially storing read line data. The SAF 15 is a memory that compresses and stores image data obtained by document storage and memory reception. The page memory 16 is a memory for developing raw data when printing image data. The SCU 17 controls the scanner 18. The scanner 18 reads a document. The PCU 19 controls the plotter 20. The plotter 20 prints out image data. The operation port 11 includes various keys and buttons necessary for the operator to operate the facsimile machine 10, and LCDs and LEDs for notifying the operator of the state of the facsimile machine 10. The DMAC 22 is a DMA controller that transfers read image data from the SCU 17 to the line buffer 14 and transfers image data developed in the page memory 16 to the PCU 19. The DCR 23 encodes (modulates, compresses) or decodes (demodulates, expands) image data. The modem 24 transmits and receives data via the NCU 25. The NCU 25 controls communication with a network such as a public line network.
[0012]
According to the facsimile apparatus 10 of the present embodiment having such a configuration, the image data at the time of reception is directly expanded in the page memory 16 and the image data is stored in the SAF 15 in parallel with the direct reception for printing out. Memory reception. The flow of image data for direct reception is as follows: modem 24 → DCR 23 → page memory 26 → PCU 19 → plotter 20. The data flow at the time of memory reception is as follows: modem 24 → DCR 23 → SAF 15.
[0013]
Next, the operation of the facsimile apparatus of this embodiment will be described with reference to FIG. 2 showing an operation flow. First, in the direct reception operation, the facsimile apparatus 10 is capable of operating the plotter and constantly monitors the number of lines in the page memory 16 and sets the number of lines to a certain number of lines (the number of lines that can be printed on one sheet of recording paper). Is reached, or when the development of the image data for one page is completed, the image data printing operation is performed (step S101; YES, step S102). At this time, when a sheet of an appropriate size is selected from the number of lines and the image data width (A3 width, B4 width, A4 width), the paper feeding operation is started (step S103). The selected sheet is conveyed from the sheet cassette to the writing start position. In order to specify the writing start position, a sensor (hereinafter referred to as a registration sensor) for detecting the leading edge of the sheet is provided immediately before the writing start position on the transport path, and a paper width sensor (B4 width detection, A3 width detection). In addition to the registration sensor, a sensor (hereinafter referred to as a conveyance sensor) that is turned on while paper is passing is provided near the exit of the paper feed cassette. The paper length can be measured from the ON time of the transport sensor, and the paper width can be classified into three types when the paper width sensor is ON when the registration sensor is ON. In the case where the registration sensor is turned on before the conveyance sensor is turned off, it is impossible to specify the sheet length before the start of writing, so that this embodiment cannot be implemented.
[0014]
Here, the sheet size estimated from the measured sheet length and sheet width is shown in Table 1 below. However, in consideration of the error, the case where the paper length of each size ± 2 mm was included in the category of the standard size was used.
[0015]
[Table 1]

[0016]
As shown in Table 1, after a certain period of time has passed after the trailing edge of the sheet has passed the transport sensor, the leading edge of the sheet reaches the writing start position. If the recognized paper size matches the actual paper size, printing is performed as usual (step S104; YES, step S107). If the sizes do not match (step S104; NO), it is determined whether or not rotation output is possible (step S105). If possible (step S105; YES), the printing operation is started after performing rotation processing (step S106). , S107). On the other hand, if the rotation process is not possible, the process ends as a size error (step S105; NO, step S109). Then, the printing operation ends normally, and if there is a next page, the process returns to step S102 and repeats (step S110; YES), and if there is no next page, the process ends (step S110; NO). However, there is a case in which the paper is originally fed for rotational output, but the size does not match, and if the output is non-rotation, it is determined that the output is possible and the output is performed without rotation. If it is determined that the actual paper size is not the standard size (irregular size), a size error is unconditionally determined.
[0017]
As described above, even if the size mismatch occurs, the printing is continued, so that it is not necessary to set (or set the size of) the paper. In addition, since it is not a memory substitute reception, it is advantageous in immediacy, and it is possible to avoid a communication error or a reception rejection due to a memory full.
[0018]
Here, the following Table 2 shows a determination when the recognized paper size is different from the actual paper size. In the table, ：: normal output, rotation: rotation output, ×: error.
[0019]
[Table 2]

[0020]
Next, in the above-described printing operation at the time of direct reception, when the distance from the exit of the paper feed cassette (the position of the transport sensor) to the position of the registration sensor is shorter than the length of the fed paper, Since the trailing edge of the sheet has not passed through the transport sensor, it cannot be determined whether or not the sizes do not match. In this case, when the trailing edge of the sheet has passed through the conveyance sensor, the size is determined. If the sizes match, the sheet currently being output is determined to be normally terminated. If the sizes do not match, it is determined that the process has ended abnormally, and after the sheet is discharged, re-output is attempted. At the time of re-output, if the rotation output is possible, re-output is performed according to the result of the size measurement.
[0021]
Such an operation will be described below with reference to FIG. 3 showing the operation flow. First, the plotter is operable, and in the direct receiving operation, the sheet feeding operation is started, and the printing operation is also started (step S201; YES). , Steps S202 to S204). Then, it is determined whether or not the paper sizes match, and if they do match, the printing operation is terminated as normal (step S205; YES, step S211). If they do not match, the printing operation ends as abnormal (step S211). S205; NO, step S206). Then, after abnormal termination, it is determined whether or not rotation output is possible (step S207). If possible (step S207; YES), sheet feeding is started again (step S208), and rotation processing is performed on the fed sheet. (Step S209), the printing operation is started (Step S210). On the other hand, if the rotation process is not possible, the process ends as a size error (step S207; NO, step S212). Then, the printing operation ends normally, and if there is a next page, the process returns to step S202 and repeats (step S211, step S213; YES). If there is no next page, the process ends (step S213; NO).
[0022]
As described above, since there is no restriction due to the mechanical layout, that is, the distance from the transport sensor to the writing start position, it is possible to cope with a smaller device.
[0023]
Next, in the above-described printing operation at the time of direct reception, when it is determined that the sizes do not match, it is determined whether reduced printing is possible. If printing is possible if the image is reduced, the image is reduced and output. If printing is not possible (irregular size), a size error is generated. The scaling factor is calculated for each of the main scanning and the sub-scanning, and the smaller value is adopted. If the actual paper size is larger in both length and width than the recognized paper size, it is output at 1: 1.
[0024]
Next, Table 3 below shows the scaling ratio (%) when the recognized paper size is different from the actual paper size.
[0025]
[Table 3]

[0026]
The magnification is determined by comparing the recognized paper size with the actual paper size when it is determined that the size does not match. If the scaling ratio is determined by comparing the length and width of the sheet size, a more optimal scaling ratio can be obtained. For example, if a B5 document is received and the recognized paper size is A4 width and the actual paper size is B5 width, the image is reduced to 86.5% and printed according to the above scaling factor. If the magnification is calculated based on the main scanning and sub-scanning of the data, printing is performed at 100% (actual magnification).
[0027]
Such an operation will be described below with reference to FIG. 4 showing the operation flow. First, the plotter is operable, and the sheet feeding operation is started in the direct receiving operation (step S301; YES, steps S302, S303). Then, it is determined whether or not the paper sizes match, and if they match, the printing operation is determined to be normal and the process ends (step S304; YES, steps S307 and S308). On the other hand, if they do not match, it is determined whether the actual paper size can be reduced and output (step S305). If reduced output is possible (step S305; YES), after performing a reduction process (step S306), a printing operation is started (step S307). On the other hand, if the reduction process is not possible, the process ends as a size error (step S305; NO, step S309). Then, the printing operation ends normally, and if there is a next page, the process returns to step S302 and repeats (step S308, step S310; YES), and if there is no next page, the process ends (step S310; NO).
[0028]
In this way, even if a size mismatch occurs, printing is continued, so that there is no need to set (or set the size of) the paper, and there is no need for memory substitute reception, which is advantageous in terms of immediacy and communication with memory full. Avoid errors and rejections.
[0029]
Here, in the above-described printing operation at the time of the direct reception, when the distance from the exit of the paper feed cassette (the position of the transport sensor) to the position of the registration sensor is shorter than the length of the fed paper, Since the trailing edge of the sheet has not passed through the transport sensor, it cannot be determined whether or not the sizes do not match. In this case, when the trailing edge of the sheet has passed through the conveyance sensor, the size is determined. If the sizes match, the sheet currently being output is determined to be normally terminated. If the sizes do not match, it is determined that the process has ended abnormally, and after the sheet is discharged, re-output is attempted. At the time of re-output, according to the size measurement result, re-output is performed if reduced output (including the same size) is possible, and if not possible (in the case of irregular size), a size error is detected, Wait for reset.
[0030]
Such an operation will be described below with reference to FIG. 5 showing the operation flow. First, the plotter is operable, and in the direct receiving operation, the sheet feeding operation is started, and the printing operation is also started (step S401; YES). , Steps S402 to S404). Then, it is determined whether or not the paper sizes match, and if they match, the printing operation ends normally (step S405; YES, step S411), but if they do not match, the printing operation ends abnormally (step S411). S405; NO, step S406). Then, after abnormal termination, it is determined whether or not reduction output is possible (step S407). If possible (step S407; YES), sheet feeding is started again (step S408), and the fed sheet is subjected to reduction processing. (Step S409), the printing operation is started (Step S410). On the other hand, if the reduction process is not possible, the process ends as a size error (step S407; NO, step S412). Then, the printing operation ends normally, and if there is a next page, the process returns to step S402 and repeats (step S411, step S413; YES), and if there is no next page, the process ends (step S413; NO).
[0031]
As described above, since there is no restriction due to the mechanical layout, it is possible to cope with a smaller device.
[0032]
It should be noted that the present invention is not limited to the above embodiment, and it goes without saying that various modifications and substitutions can be made within the scope of the claims.
[0033]
【The invention's effect】
As described above, the present invention measures the length and width of a recording sheet fed from a sheet feeding unit capable of continuously printing on a fixed-size recording sheet, and records the length and width of the recording sheet recognized by the apparatus. This is a control method for a facsimile apparatus capable of detecting a size error different from the paper size. If the size mismatch is detected before recording the received image data, the size of the recording paper is predicted from the measured length and width of the recording paper. If the predicted recording paper size is a recording paper size that does not impair the received image data if the rotation output is performed, the rotation output is performed without stopping the printing operation. Therefore, it is possible to provide a facsimile apparatus which can always receive data without over-memory and has high immediacy.
[0034]
If a size mismatch is detected during the recording of the received image data, the size of the recording paper is predicted from the measured length and width of the recording paper. Then, if the predicted recording paper size is a recording paper size that does not impair received image data if rotational output is performed, the recording paper being recorded is ejected, and then the same image data is re-outputted by rotational output. Therefore, there is no restriction due to the mechanical layout, and a smaller device can be accommodated.
[0035]
Further, when the size mismatch is detected before the recording of the received image data, the recording paper size is predicted from the measured length and width of the recording paper. If the predicted recording paper size is a recording paper size that does not impair received image data if the reduced printing is performed, the reduced printing is performed without stopping the printing operation. Therefore, it is always receivable and has high immediacy.

If the size mismatch is detected before recording the received image data, the size of the recording paper is predicted from the measured length and width of the recording paper. Then, if the predicted recording paper size is a recording paper size that does not impair received image data if reduced printing is performed, the recording paper being recorded is discharged, and then the same image data is re-output with reduced output. Therefore, there is no restriction due to the mechanical layout, and a smaller device can be accommodated.
