Description

  The present invention relates to control devices such as various printers, copiers, and facsimile machines, and more particularly to a recognition mark generation method in a printer control device.

  Confirm the contents of the printed matter by printing a recognition mark across the perforation of the continuous recording paper to facilitate the sorting of the printed matter on a bundle of printed matter consisting of a large number of printed continuous recording papers There is a method of recognizing a break of a job in a folded state without doing it.

  For example, in Patent Document 1 (Japanese Patent Laid-Open No. 10-44552), a recognition mark is generated so as to straddle the boundary of an image forming area corresponding to the size of continuous recording paper, and the generated recognition mark and image print data are combined. Thus, a printing method has been proposed.

  Similarly, in Patent Document 2 (Japanese Patent Laid-Open No. 1-125265), a signal indicating the position of a mountain fold perforation of continuous recording paper is received, the position of the mountain fold perforation is known from the signal, and the mountain fold perforation is straddled. A method for printing a rectangular recognition mark pattern is proposed.

  Patent Document 3 (Japanese Patent Laid-Open No. 2-55174) proposes a method of printing a recognition mark on a sprocket hole separating portion in order to lose waste paper.

  The methods described in the above publications have the following problems. The method described in Patent Document 3 is a method of recognizing a job break by printing one type of recognition mark on the sprocket hole separating portion over several pages from the job start page. Therefore, when a one-page job is printed, recognition marks are continuously printed before and after the one-page job. For this reason, it is not possible to recognize a break between jobs on one page.

  In the method described in Patent Document 2, a dedicated mechanism must be provided to recognize the position of the perforation.

  Further, in the method described in Patent Document 1, when the function of shifting the image print data in the main scanning direction and the sub-scanning direction by the operator for handling preprinted paper is operated from the operation unit, it is recognized together with the image print data. In some cases, the mark also shifts and the recognition mark cannot be printed across the perforation.

  For example, as shown in FIG. 6, the lower recognition mark 103 printed on the lower perforation for the N page image formation area 102 and the upper perforation for the (N + 1) page image formation area 104. When the upper recognition mark 105 to be printed is printed on the sprocket hole separating portion 101, if the lower recognition mark 103 and the upper recognition mark 105 are put on the sprocket hole 100, printing stains are generated. In order to avoid this, the length of the lower recognition mark 103 and the upper recognition mark 105 is smaller than the distance from the perforation to the sprocket hole. Here, as shown in FIG. 7, when the lower recognition mark 103 and the upper recognition mark 105 are shifted in the negative direction by a value L larger than the recognition mark length, the lower recognition mark 103 is placed across the perforation. In addition, the upper recognition mark 105 cannot be printed. In addition, there is a problem that the lower recognition mark 103 or the upper recognition mark 105 is caught in the sprocket hole 100 and printing stains occur.

  The object of the present invention is not to provide a dedicated mechanism for recognizing the position of the perforation, and even if the operator shifts the image print data from the operation unit, a plurality of recognitions are made on the sprocket hole separation part so as to straddle the perforation. An object of the present invention is to provide a printer control device that can print a mark and prevent a recognition mark from being applied to a sprocket hole.

In order to achieve the above object, the invention described in claim 1 includes a data receiving unit that receives data transmitted from a host computer, a main control unit that analyzes the received data and controls the entire printer control unit. An editing processing unit that edits the data analyzed by the main control unit, a page expansion unit that expands the print data in bitmap format based on the edited data, and the bitmap format data A page memory for storing print page data, a data transfer control unit for storing print page data from the page memory to the line buffer, a print data output unit for transmitting the print page data stored in the line buffer to the printer, and an image A printer control device having an operation unit having a function of shifting print data in the main scanning direction and the sub-scanning direction. Te,
A main scanning direction image print data correction value setting register for setting a deviation amount in the main scanning direction of the image print data set by the operation unit, and a sub scanning direction deviation amount of the image print data set by the operation unit. Sub-scanning direction image print data correction value setting register to be set, upper recognition mark selection register for storing the type of recognition mark for the upper perforation in the image forming area, and type of recognition mark for the lower perforation in the image forming area The lower recognition mark selection register for storing the image, the mode setting register for setting whether normal printing or copy printing, the paper conveyance synchronization counter for recognizing the perforation of continuous recording paper, and the print data of the sprocket hole separation part By providing a sprocket hole separation part print data generation part that generates the Even when the image print data is shifted in the main scanning direction and the sub-scanning direction by the operation unit without providing a special mechanism, a plurality of recognition marks can be printed on the sprocket hole separating portion so as to straddle the perforation. It is characterized in that the recognition mark is not hung on the hole.

  According to a second aspect of the present invention, in the first aspect, the paper conveyance synchronization counter changes a timing for starting counting according to a value of the sub-scanning direction image print data correction value setting register, and It is characterized in that it operates so that the value of the counter becomes the value of the sheet length on the perforation.

  According to a third aspect of the invention, in the first or second aspect of the invention, the paper conveyance synchronization counter holds the value of the counter even when the continuous recording paper conveyance is stopped, so that even when printing is resumed, The recognition mark on the page is continuously printed.

  According to a fourth aspect of the present invention, in the first aspect, the values of the lower recognition mark selection register and the mode setting register are valid at the reset timing of the paper conveyance synchronization counter during continuous printing. It is a feature.

  According to a fifth aspect of the present invention, the upper recognition mark selection register according to the first aspect is based on the value of the mode setting register at the reset timing of the paper conveyance synchronization counter, and the previous page during normal printing. The value set in the lower recognition mark selection register is stored, and at the time of copy printing, the value set in the upper recognition mark selection register on the previous page is stored.

  According to another aspect of the present invention, there is no dedicated mechanism for recognizing the position of the perforation, and even when the image print data is shifted in the main scanning direction and the sub scanning direction by the operation unit, the perforation is straddled. In addition, it is possible to print a plurality of recognition marks on the sprocket hole separating portion and to prevent the recognition marks from being applied to the sprocket holes.

  In the paper transport synchronization counter according to claim 2, the timing for starting the counting is changed according to the value of the sub-scanning direction image print data correction value setting register, and the counter value becomes the paper length value on the perforation of the continuous recording paper. Therefore, it is possible to recognize the perforation of the continuous recording paper without providing a dedicated mechanism for recognizing the position of the perforation.

  In the paper conveyance synchronization counter according to the third aspect, since the counter value is held even when conveyance of the continuous recording paper is stopped, it becomes possible to continuously print the recognition mark on the previous page even when printing is resumed. The same recognition mark can be printed during continuous printing and intermittent printing.

  The values of the lower recognition mark selection register and the mode setting register according to claim 4 are valid at the timing of resetting the paper conveyance synchronization counter during continuous printing. It is possible to prevent printing and correctly print the recognition mark.

  The upper recognition mark selection register according to claim 5 stores the value set in the lower recognition mark selection register on the previous page at the time of normal printing based on the value of the mode setting register at the reset timing of the paper conveyance synchronization counter. Since the value set in the upper recognition mark selection register on the previous page is stored at the time of copy printing, even when the image print data is set to be shifted in the positive direction in both the main scanning direction and the sub-scanning direction, The upper recognition mark on the next page can be printed.

FIG. 10 is a diagram when image print data is set to be shifted in the negative direction in both the main scanning direction and the sub-scanning direction during normal printing. FIG. 10 is a diagram when image print data is set to be shifted in the negative direction in both the main scanning direction and the sub-scanning direction during copy printing. FIG. 10 is a diagram when image print data is set to be shifted in the positive direction in both the main scanning direction and the sub-scanning direction during normal printing. FIG. 10 is a diagram when image print data is set to be shifted in the positive direction in both the main scanning direction and the sub-scanning direction during copy printing. It is a figure at the time of printing a recognition mark by conventional technology. It is a figure at the time of operating the function which shifts image print data to a subscanning direction with respect to the prior art.

  FIG. 1 shows an overall schematic block diagram of a recognition mark generation method according to an embodiment of the present invention.

  First, when the operator performs setting for shifting the image print data in the main scanning direction and the sub-scanning direction by the operation unit 9, the main control unit 2 sets the predetermined address in the printer based on the value set in the operation unit 9. By rewriting the set value, the writing start position of the image print data output from the print data output unit 8 is changed.

  Next, after the data receiving unit 1 receives the data transmitted from the host computer, the data received by the main control unit 2 is analyzed and transmitted to the editing processing unit 3. The edit processing unit 3 edits the transmitted data into a command / parameter for expansion processing, and transmits the command / parameter to the page expansion unit 4. The page expansion unit 4 expands the bit map format image print data in the page memory 5 in accordance with the command and parameter. After the image print data for one page is developed in the page memory 5, the main control unit 2 sets the head address and the transfer number of the image print data developed in the page memory 5 in the data transfer control unit 6.

  Further, the main control unit 2 sets the sheet width and sheet length of continuous recording sheets in the sheet width setting register 10 and the sheet length setting register 11, and the main scanning direction and sub-scanning direction deviation amounts set by the operation unit 9. The direction image print data correction value setting register 12 and the sub-scanning direction image print data correction value setting register 13 are set, and printing is performed on the perforation in the upper part of the image forming area from the command included in the data transmitted from the host computer. The upper recognition mark selection register 14 sets the type of the upper recognition mark to be printed, the lower recognition mark selection register 15 sets the type of the lower recognition mark to be printed on the perforation in the lower part of the image forming area, and the mode for normal printing or copy printing. Set in the setting register 16. After the register setting by the main control unit 2, the data transfer control unit 6 transfers the image print data from the page memory 5 to the line buffer 7 based on the transfer start address and the transfer number. After the image print data is transferred to the line buffer 7 to some extent, the print data output unit 8 reads the image print data from the line buffer 7 in synchronization with the image print data request signal from the printer, and the read one line of image print data Is sent to the printer in bytes.

  Here, as shown in FIG. 2, during normal printing, when the image print data is set to be shifted in the negative direction in both the main scanning direction and the sub-scanning direction, the image print data from the printer is set. When the request signal is received, white data is generated from the sprocket hole separation portion image print data generation portion 20 and sent to the printer in byte units. Each time 1-byte white data is sent to the printer, the paper width counter 17 counts up, and after sending white data for the width N of the sprocket hole separation part to the printer, the image print data is read from the line buffer 7 and the paper is read. The value set in the width setting register 10 is sent to the printer. If one line of image print data read from the line buffer 7 is larger than the value set in the paper width setting register 10, the image print data is read from the line buffer 7 but not sent to the printer. After the one-line image print data is sent to the printer, the paper length counter 18 is counted up, and the above operation is performed until the paper length counter 18 reaches the value Y set in the sub-scanning direction image print data correction value setting register 13. If the sheet length counter 18 reaches the value Y set in the sub-scanning direction image print data correction value setting register 13 repeatedly, the sheet conveyance synchronization counter 19 is enabled.

  In this state, when an image print data request signal is received from the printer, white data of (N1 + X) is generated by the sprocket hole separation portion image print data generation unit 20, and then the recognition set in the upper recognition mark selection register 14 is performed. A mark pattern is generated and sent to the printer. After sending the white data for the width N of the sprocket hole separating portion and the pattern of the recognition mark to the printer, the image print data is read from the line buffer 7 and sent to the printer. At this time, since the start position of the recognition mark is shifted by X, the image print data and the pattern of the recognition mark may be overlapped. The transmission of the recognition mark pattern is repeated in the same manner until the paper conveyance synchronization counter 19 indicates the recognition mark length M2. Data and image print data are repeatedly transmitted in the same manner. When the paper conveyance synchronization counter 19 reaches the value of ((M1-M2) -1), the sprocket hole separation part image print data generation part 20 generates (N2 + X) white data, and the lower recognition mark selection register 15 The pattern of the recognition mark set to “1” is generated, and then the image print data is read from the line buffer 7 and sent to the printer.

  The white data, the pattern of the recognition mark, and the image print data are repeatedly sent to the printer in the same manner as when the upper recognition mark is generated until the paper conveyance synchronization counter 19 reaches the value M1. After the paper transport synchronization counter 19 reaches the value M1, the paper transport synchronization counter 19 is reset while the paper transport synchronization counter 19 is enabled, and the lower part of the next page set during the transmission of the image print data to the printer. The values of the recognition mark selection register 15 and the mode setting register 16 are made valid. Regarding the setting of the upper recognition mark selection register 14 on the next page, the pattern is the same as the lower recognition mark on the previous page during normal printing. Therefore, the lower recognition mark selection register on the previous page is set at the timing when the value of the register is validated. The value of 15 is stored in the upper recognition mark selection register 14 on the next page. In this state, when the image print data request signal is received from the printer, the upper recognition mark and the image print data are transferred to the paper transport while the value of the paper transport synchronization counter 19 is 0 to (M2-1), as in the previous page. When the value of the synchronization counter 19 is between ((M1-M2) -1) to (M1-1), the lower recognition mark and image print data are sent to the printer, and at other times, white data and image print data are sent to the printer. Accordingly, the lower recognition mark having the recognition mark length M2 is printed on the upper part of the perforation and the upper recognition mark having the recognition mark length M2 is printed on the lower part of the perforation so as to straddle the perforation.

  During intermittent printing, sending of the lower recognition mark is stopped when the value of the paper conveyance synchronization counter 19 is between ((M1-M2) -1) to (M1-1), but the paper conveyance synchronization counter 19 must be reset. First, since the process waits with the counter value held, when the printing of the next page is resumed, the lower recognition mark can be continuously printed. The paper conveyance synchronization counter 19 is disabled and reset by software only when out of paper and NPRO operation.

  Next, as shown in FIG. 3, the operation when the image print data is set to be shifted by (−X, −Y) in the negative direction in both the main scanning direction and the sub-scanning direction during copy printing will be described.

  At the time of printing the first page, the same operation as normal printing is performed until the paper conveyance synchronization counter 19 reaches the value M1. After the paper transport synchronization counter 19 reaches the value M1, the paper transport synchronization counter 19 is reset while the paper transport synchronization counter 19 is enabled, and the lower part of the next page set during the transmission of the image print data to the printer. The values of the recognition mark selection register 15 and the mode setting register 16 are made valid. Regarding the setting of the upper recognition mark selection register 14 on the next page, since the same pattern as the upper recognition mark on the previous page is obtained during copy printing, the upper recognition mark selection register on the previous page is set at the timing when the value of the register is made valid. The value of 14 is stored in the upper recognition mark selection register 14 on the next page. Thereafter, the recognition mark and image print data of the next page are sent to the printer as in normal printing. Even during intermittent printing, the same operation as during normal operation is performed.

  Next, as shown in FIG. 4, the operation when the image print data is set to be shifted in the positive direction in both the main scanning direction and the sub-scanning direction during normal printing will be described.

  When the main control unit 2 sets the sub-scanning direction image print data correction value setting register 13 to shift in the positive direction of sub-scanning (X, Y), the paper transport synchronization counter 19 is enabled at the set time. At the same time, the value of the paper transport synchronization counter 19 is changed to the value Y set in the sub-scanning direction image print data correction value setting register 13.

  When the value of the paper conveyance synchronization counter 19 is 1 to (M2-1), when the image print data request signal is received from the printer, the white data of (N1-X) is received from the sprocket hole separation portion image print data generation unit 20. After that, the recognition mark pattern set in the upper recognition mark selection register 14 is generated and sent to the printer, and the white data for the width N of the sprocket hole separation portion and the recognition mark pattern are sent to the printer. Reads out the image print data from the line buffer 7 and sends it to the printer. Subsequent operations and operations on the next page are the same as those performed when the image print data is set to be shifted in the negative direction in both the main scanning direction and the sub-scanning direction during normal printing. As for the operation during intermittent printing, when printing is stopped, it is necessary to print the upper recognition mark on the next page without setting the next page, but after the paper transport synchronization counter 19 reaches the value of M1, During normal printing, since the value of the lower recognition mark selection register 15 of the previous page is stored in the upper recognition mark selection register 14 of the next page, the printing shown in A becomes possible and stops after printing A.

  When printing is resumed, if the sub-scanning direction image print data correction value setting register 13 is set to shift in the positive direction of sub-scanning, the values of the set lower recognition mark selection register 15 and mode setting register 16 are valid. To start the operation. Subsequent operations are the same as those performed when the image print data is set to be shifted in the negative direction in both the main scanning direction and the sub-scanning direction during normal printing.

  Next, as shown in FIG. 5, the operation when the image print data is set to be shifted (X, Y) in the positive direction in both the main scanning direction and the sub-scanning direction during copy printing will be described.

  When the first page is printed, the same operation as that in the case where the image print data is set to be shifted in the positive direction in both the main scanning direction and the sub-scanning direction during normal printing is performed until the paper conveyance synchronization counter 19 reaches the value of M1. Do. After the paper transport synchronization counter 19 reaches the value M1, the paper transport synchronization counter 19 is reset while the paper transport synchronization counter 19 is enabled, and the lower part of the next page set during the transmission of the image print data to the printer. The values of the recognition mark selection register 15 and the mode setting register 16 are made valid. Regarding the setting of the upper recognition mark selection register 14 on the next page, since the same pattern as the upper recognition mark on the previous page is obtained during copy printing, the upper recognition mark selection register on the previous page is set at the timing when the value of the register is made valid. The value of 14 is stored in the upper recognition mark selection register 14 on the next page. Thereafter, the recognition mark and image print data of the next page are sent to the printer in the same manner as when the image print data is set to be shifted in the positive direction in both the main scanning direction and the sub-scanning direction during normal printing. Even during intermittent printing, the same operation as that in the case of setting for shifting the image print data in the positive direction in both the main scanning direction and the sub-scanning direction during normal operation is performed.

  According to the present invention, a dedicated mechanism for recognizing the position of the perforation is not provided, and even when the image print data is shifted, a plurality of recognition marks can be printed on the sprocket hole separating portion so as to straddle the perforation. At the same time, it is possible to prevent the recognition mark from being applied to the sprocket hole, and the object can be achieved.
