Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer using continuous paper having folding perforations, and more particularly to a printer capable of securing a binding margin and controlling a separator page serving as a cover, and a pile of continuous paper. The present invention relates to a recognition mechanism for recognizing a folded / valley fold shape.

With the recent development of office automation, electrophotographic printing apparatuses such as laser printers are widely used in output terminals of computers, facsimile machines, copying machines and the like.

Although these devices are progressing toward low noise, high functionality, and high speed, there is a strong demand for higher speed. The higher the speed, the greater the burden on the operator who handles continuous forms (hereinafter referred to as forms) (such as checking the requester name and sorting), so it is necessary to reduce the load.

The printed paper is cut for each print job and folded in a zigzag at the perforations to file, but when the printed paper is bound at the upper end and filed, the valley-folded portion of the fold is the printing position. Is close to the top, making it difficult to see.

In addition, for example, in a printer such as a print center that prints a large amount of computer program lists,
First page of printing (However, valley fold page)
And the job information such as print job name, date and time, and name are printed on the page after the last page (however, the folding mountain fold page), but if the first page is not a valley fold page or the last page If the next page is not a mountain break page, skip one page and print on the next page.

However, the operator inputs mountain fold / valley fold information from the operation panel at the time of initial setting of paper and stores it in the printer. As a result of converting to →, the stored mountain fold / valley fold information may be the reverse of the actual paper mountain fold / valley fold, and the job information page may not always appear in the folded state. It is inconvenient because it is necessary to turn over the folded page in such a case.

Therefore, there is a demand for a method of printing with a binding margin for filing and a method of printing so that the print page of the job information always appears on the surface.

2. Description of the Related Art FIG. 20 illustrates an internal side view of a laser printer to which the present invention is applied. In the figure, reference numeral 1 is a paper feed unit for accumulating and accommodating sheets 2a folded at perforations, and 3
Reference numerals a and 3b are tractors, 30 is an automatic load table, 4a is a transport path, 5a is a printer section, 6 is a cutting section, 7 is a swing guide, and 8 is a stacker table.

The printer unit 5a includes an optical unit 50, a photosensitive drum 51 as an image forming body, a cleaner 52, a charger 53, a developing device.
54, a transfer device 55, a static eliminator 56, and a fixing device 57. A cut portion 6 is provided at the end of the transport path 4a, and cuts at a perforation each time one print job is completed.

With such a configuration, first, when the power supply of the apparatus is turned on and the paper 2a is loaded in the paper feeding unit 1, the size of the paper 2a is detected by the size sensor S, and the control unit (not shown) is displayed. Remembered. The size sensor S is composed of a plurality of optical sensors shielded according to the paper size.

Next, as shown by the one-dot chain line, the perforation (for example, the leading edge) of the paper 2a is set to the designated position a on the auto load table 30, and the auto load button is depressed to drive the drive mechanism (not shown). As a result, the auto load table 30 moves in the direction of the tractor 3a, and the sprocket 31 provided with the feed holes at both ends of the paper on the belt B of the tractor 3a.
And the tractors 3a, 3b and the feed roller R are driven in the direction of arrow A, and the paper of a predetermined number of pages of the stored size
2a is sent.

The sheet 2a is the swing guide 7 (sheet
A pair of oscillating plates facing each other with an interval 2a passing through are rotatably supported at the upper ends and oscillate in the same direction), and the leading ends are guided on the stacker table 8 with perforations. Fold it up and stop as it is accumulated,
The print standby state is set.

Then, the fixing device 57 is heated to a predetermined temperature and becomes ready for printing. The photosensitive drum 51 has already been neutralized by the static eliminator 56, the residual toner is cleaned by the cleaner 52, and is charged again by the charger 53.

Thus, a host computer (not shown)
Print job data consisting of commands, print data, and job information (print name, date and time, name, etc.) from (hereinafter referred to as the host) together with the command, as shown in FIG. 21 (a),
The job information (previous separator) is sent to the first page, the print data is sent from the next page, and the job information (post separator) is sent to the page next to the last page of the print data.

Then, according to the command, the front separator,
After the print data and the post-separator are expanded page by page in a bitmap memory (not shown), they are converted into optical data by an optical unit 50 including a laser light source and the photosensitive drum 51 is scanned.

The electrostatic latent image formed on the photosensitive drum 51 is a developing device.
The toner image is developed at 54 and transferred to the paper 2a that is being transferred.
After being transferred by 55, it is fixed by the fixing device 57 and is sequentially folded and accumulated on the stacker table 8.

The upper and lower margins (print prohibited area) of the paper 2a on which the print data is printed are generally set to have a wide upper margin and a narrow lower margin. In addition, the rear separator is printed on the page next to the last page of the print data, and as shown in Fig. 21 (b), the paper is printed at the perforation at the end of the rear separator page.
2a is cut by the cutting part 6. Cut paper 2a
Are fed by the feed roller R and are folded and accumulated.

The method for printing the front separator page and the rear separator page is as follows.
When set to 30, the operator inputs the mountain fold / valley fold information of the perforation fold from the operation panel (not shown) and stores it in the printer, and the previous separator page is printed on the first valley fold page and the mountain fold / Every time one page of valley fold information is printed, it is stored by switching it to mountain → valley → mountain →, and if the next page after the last page is a mountain fold, print the subsequent separator page on that page and select the valley fold. For example, one page is skipped and printed on a mountain page. Therefore, the front separator and the rear separator are always exposed.

Here, the mountain folds / valley folds are, as shown in FIG. 21 (c), upward protrusions / downward depressions of perforations on the printing surface of the sheet 2a. A mountain fold page / valley fold page refers to a page following the mountain fold / valley fold.

In this way, the print jobs are sequentially printed and accumulated on the stacker table 8. When a predetermined amount of sheets 2a is stacked on the stacker table 8, a stacker full sensor (not shown) detects and informs the stacker table 8. Therefore, the operator removes the stacked sheets 2a from the stacker table 8 and prints each stack for each print job. The folded paper 2a is bound at the upper end portion by, for example, a stapler or the like and filed.

[0021]

According to the above-mentioned conventional method, when the paper is initially set, the operator inputs the mountain fold / valley fold information of the paper set from the operation panel. If the information opposite to the actual mountain fold / valley fold shape is entered, the front separator will be printed on the mountain fold page and the rear separator will be printed on the valley fold page. Since it is not possible, the operator has to turn the page and check the print job, which increases the work load. Especially when a large number of print jobs are handled, the burden becomes large. Also, in order to use the folded printed paper as a heading for storing / using each job, copy three copies of the rear separator,
There is also a method of binding the sheets before and after binding, but the paper and the printing time are wasted except when an input error occurs.

Since the paper on which the print data is printed has a wide upper margin and a narrow lower margin, when the sheets are folded for each print job and bound at the upper end, the margins of the front and back pages are the same. Since it is different, pages with narrow margins are hard to read, which is inconvenient for utilizing the materials. There is a problem.

Therefore, it is not necessary to input the operator's mountain fold / valley fold information, or even if there is an input error, it is automatically corrected, and the separator appears on the surface after printing, making it easy to confirm the print job. A printing method is desired, and a mountain folding page is printed, that is, a printing method that does not make it difficult to read a page to be folded even when folded for each print job and bound at the upper end.

According to the present invention, the detection mechanism capable of easily detecting the shape of the perforation / valley fold of the perforation of the paper, and the separator appearing on the surface after printing to facilitate confirmation of the print job, and printing An object of the present invention is to provide a printer that can print a rolled-up page so that it can be easily read even when folded for each job and bound at the upper end.

(1) First, as described in the conventional example, when the paper 2a is set on the auto load table 30, the operator inputs the perforation shape (a mountain fold or a valley fold) by the mountain / valley switch 141. The entered information is the mountain / valley information control unit.
The flag corresponding to the mountain / valley is set in the mountain / valley information file 130 by 110.

(2) When the operator depresses the auto load button 140, the paper 2a is conveyed by driving the tractors 3a and 3b, and the peak / valley detecting section 9a detects the shape of the first perforation of the paper 2a.

(3) As for the detection result, the mountain / valley discriminating unit 113 discriminates a mountain fold / valley fold, and the discrimination result and the mountain / valley information read from the mountain / valley information file 130 are compared with each other.
Compare with 114.

(4) As a result of the comparison, if they match, a predetermined number of pages are sent and the autoloading is completed. During this period, every time one page is sent, the peak / valley information control unit 110 inverts the peak / valley information flag of the peak / valley information file 120.
(Same as below.) (5) If there is a mismatch as a result of comparison, after sending a specified number of pages, "Press the page feed button" is displayed on the display 144 and the buzzer 145 rings. Then, the operator is notified of the disagreement.

(6) Then, the operator pushes the page forward button 14
When 3 is pressed, one page is fed by the conveyance control unit 111 in accordance with a command from the mountain / valley skip control unit 117, and the autoloading ends. Mountain / valley information file 130
The peak / valley information of s is switched to accurate information.

(7) Then, the print start button 142 is pressed to notify the host 18, and the host 18 starts transmitting the print job data. (8) When the print job data is received, the print job data analysis unit 116 refers to the peak / valley information flag of the peak / valley information file 130 and confirms that it is the same valley fold page as the valley fold specification of the command on the previous separator page. The print start line control unit 118a, the print start line control unit 118a
The print start line with the large margin set in 12a is read out, and the conveyance control unit 111 and the print control unit 119 are instructed to print the front separator as shown in FIG. 12 (a).

(9) If the flag of the mountain / valley information is mountain fold, the mountain / valley skip control unit 117a skips one page to make a valley fold page, and prints from the printing start line with a large margin to the previous separator. Print.

(10) The next page is a mountain-folding page, and print data is printed from the print start line having the small margin set in the print start line setting unit 12. After that, the valley fold page is printed from the print start line with a large margin, and the mountain fold page is printed from the print start line with a small margin.

(11) Thus, as shown in FIG. 12 (b), the page on which the front separator is printed is folded on the stacker table 8 so that the page is on the lower side, and when the printing of the print data ends, , The print job data analysis unit 116 specifies that the mountain fold specification of the next separator command is
It is determined whether or not it matches the valley information.

(12) When the determination results are the same, the mountain / valley skip control unit 117a prints a rear separator with a small margin on the mountain-folded page, as shown in FIG. 12 (a). (13) When they do not match, the mountain / valley skip control unit 117a sets 1
Only the pages are skipped to make a mountain-folded page, and the rear separator is printed from the print start line with a small margin.

(14) When the printing of the rear separator is completed, the rear end of the page of the rear separator is cut at the cut portion 6 and folded on the stacker table 8 as described in the conventional example of FIG. 21 (b). Accumulate.

(15) When the next print job is subsequently printed, the flow from (8) is repeated. When a paper jam occurs in the above printing process and the paper is repaired, the jammed paper 2a is removed, so that the flag of the peak / valley information file 130 may be misaligned. Therefore,
The above steps (2) to (7) are performed again.

Further, even if the apparatus power is cut off due to the end of work or the like, since the peak / valley information file 130 is supported by the battery, the flag is held and the apparatus power is turned ON unless the paper 2a is set. It is not necessary to input the mountain / valley information again after printing, and printing can be continued.

14 and 15 are flowcharts of the second embodiment, and FIGS. 16 and 17 are explanatory diagrams of the second embodiment. The same reference numerals denote the same objects throughout the drawings.

The second embodiment of FIG. 13 differs from the first embodiment described with reference to FIGS. 5 and 6 in that the print job data sent from the host 18 is organized for cut sheets and When printing on the paper 2a with a grain, as shown in Figure 16 (a), specify the command of the print job data (LoadPrin
Control the print start line for each page depending on whether (t Format) is single-sided print or double-sided print.The format of the print start line is for print start line for single-sided print and valley fold for double-sided print. And three types of print start line for mountain folding are set, and as shown in Fig. 16 (b), the command specification is double-sided printing, front-side printing (front-side skip) or back-side printing
Depending on (Skip back side), it is determined whether the next page to be printed is a valley fold page or a mountain fold page, and if it does not match the flag of the mountain / valley information file 130, one page is skipped. is there.

That is, in FIG. 13, 10a is MPU and 11a
Is a ROM, 114a is a mountain / valley information comparison unit, 116a is a print job data analysis unit, 117b is a mountain / valley skip control unit, 118b is a print start line control unit, and 12a is a print start line setting unit. The configuration of the device is the same as that of the first embodiment shown in FIG.

The MPU 10a controls each part based on the control program stored in the ROM 11a. ROM11a
Is a mountain / valley information control unit 110, a conveyance control unit 111, a mountain / valley detection transfer control unit 112a, a mountain / valley determination unit 113, a mountain / valley information comparison unit 114a, an informing unit 115, a print job data analysis unit 116a, It is provided with a control program such as a mountain / valley skip control unit 117b, a print start line control unit 118b and a print control unit 119, and a print start line setting unit 12a.

The mountain / valley information comparing unit 114a is used by the mountain / valley determining unit 11
The mountain fold / valley fold shape determined by 3 is compared with the mountain / valley information flag stored in the mountain / valley information file 130 to determine whether they match. In addition, by comparing the flag of the mountain / valley information in the mountain / valley information file 130 with “the next page to be printed is a mountain fold / valley fold” analyzed by the print job data analysis unit 116a described below, whether or not they match with each other. To determine.

The print job data analysis unit 116a uses the host 18
If the instruction of the command of the print job data sent from is a single-sided printing instruction (in this case, printing is performed in the same way as when printing on cut paper)
If "double-sided printing" is specified for "No binding margin" and "Skip function is enabled" and "Binding margin is present", and if "skip function is enabled" and the command is skipped on the front side, "Next print" If the page you want to print is a valley fold page, or if the back side is skipped, then "The next page to print is a mountain fold page."
To determine. Here, the skip function is a function of skipping one page by an idle when necessary, and the binding margin and the binding margin do not need to change the print start line of the mountain-folding page.

The mountain / valley skip control unit 117b has a blank page format for one page, and the mountain / valley information comparison unit 11b.
When the comparison results of 4a do not match, the print job data analysis unit 11
When the judgment result by 6a does not match, and the page forward button 143
When is pressed, a blank page blank feed command is sent to the conveyance control unit 111 together with a blank page format.

When the judgment result of the print job data analysis unit 116a is "no binding margin", the print start line control unit 118b sets the print start line of the standard margin set in the print start line setting unit 12a described below. Is selected, and when “Binding margin” is set and “The next page to be printed is a valley fold page”, the print start line setting section 12
Select a print start line that is larger than the standard margin of a, and select a print start line that is smaller than the standard margin of the print start line setting part 12a when "Binding margin" is "The next page to be printed is a mountain fold page". And instructs the transport control unit 111 and the print control unit 119.

The print start line setting unit 12a sets the print start line "standard margin" when the one-sided print instruction (no binding margin) and the print start line of the valley fold page (when the binding margin is taken into consideration). Larger than standard margin: For example, the standard margin plus 1 line.
Hereinafter, there are three types of print start line formats: a "standard margin + 1") and a mountain-folded page print start line (smaller than the standard margin: for example, a standard margin-1 line; hereinafter referred to as "standard margin-1"). Is set.

Since it has such a structure and function, its operation will be described below with reference to the flowcharts of FIGS. 14 and 15 and the explanatory view of FIG.

(2) If it is a single-sided print instruction, the printing of each page is started with the "standard margin" set in the print start line setting unit 12a as "skip function invalid" and "no binding margin".

(3) If it is a double-sided printing instruction, it is determined that the "skip function is valid" and "the binding margin is present". (4) If "Skip function enabled" is specified and the command is skipped on the front side (usually, the print start page is the front side skipped designation), "The next page to be printed is a valley fold page."
To determine.

(5) When it is determined that the printed page is a valley fold page, the flag in the page crest / valley information file 130 is referred to, and if they match, as shown in FIG. When printing a valley fold page, print from the print start line of "standard margin + 1" (print the front separator on the first page). The flag of the mountain / valley information file 130 is reversed by turning the page. (Same as the following) (6) When they do not match, one page of blank feed is performed, and printing is performed from the print start line of "standard margin +1" set in the print start line setting unit 12a as a valley fold page.

(7) If "skip function is valid" and the command is specified as the back side skip, it is determined that "the next page to be printed is a mountain fold page". (8) When it is determined that the page is a mountain-folded page, refer to the flag of the page mountain / valley information file 130, and if they match, skip one page of the paper 2a to print the front separator, and then trough it. Turn it into a folded page, and add "standard margin + 1" as in (5).
Print from the print start line of. When they do not match, the sheet 2a is a valley-folded page, so printing is started from that page from the print start line of "standard margin +1" as in (5).
(In the subsequent printing of print data, if there is a mismatch, one page is skipped.) (9) The print data after that is discriminated in the same way as in (3) and (4), and the mountain / valley information is determined. The print page skip control is performed depending on whether the flag of the mountain / valley information of the file 130 matches / does not match, and the print start line of "standard margin +1" for the valley folded page and the "standard" for the mountain folded page. Printing is performed according to the print start line of "margin-1". FIG. 17 shows a case where the first page of the print data next to the previous separator is designated for front surface printing.

(10) After printing the print data, refer to the flag of the mountain / valley information file 130 for the mountain fold designation of the separator after the command, and if they match, the mountain fold page is directly displayed with "standard margin". The subsequent separator is printed at the print start line of "-1".

(11) When they do not match, one page is fed in the blank and then the rear separator is printed on the mountain-folded page at the print start line of "standard margin-1". (12) and the subsequent steps are the same as (15) and (16) in the flowchart of FIG. 11 described in the first embodiment.
