[Industrial applications]

The present invention relates to a printing control apparatus for a printing apparatus that automatically performs printing on a print sheet that has been cut into a standard size and has a binding hole so that a binding margin does not overlap a binding hole.

[Conventional technology]

A printing apparatus is widely used as one tool for output of a computer system, but when the printing paper is continuous paper, its size is too large to be stored and managed as it is. For this reason, the print result is reduced-size copied on a standard size paper (A3, A4, A5, B4, B5 paper, etc.) of a desired size using a copying machine, and stored in a file or the like for management.

In order to save such trouble, A3, A4, A5, B4,
Printing devices that use cut paper cut to a standard size such as B5 as printing paper and directly print on these cut papers have been used. Further, in order to simplify the file and storage of printed cut sheets, a binding device for a file is provided in advance on the cut sheet, and a printing apparatus for directly printing on the cut sheet having the binding holes has been developed. Have been.

When printing directly on a printing sheet made of such cut sheets with binding holes, the conventional printing apparatus does not have a function to consider the presence or absence of a binding hole in the cut sheet printing paper. With upper binding, lower binding, left binding,
The print data is created in accordance with the binding method in consideration of the printing result by the binding method of the paper such as right binding. Further, at the time of printing, a user selects a position of a binding hole with respect to a sheet feeding direction and performs sheet feeding so as to obtain a printing result suitable for a desired binding margin.

[Problems to be solved by the invention]

A conventional printing apparatus for printing paper made of cut sheets with binding holes has no function of considering the presence or absence of binding holes in the cut sheet to be printed, and performs printing in the same manner regardless of the presence or absence of binding holes.

For this reason, the user who performs printing creates print data in consideration of the binding holes according to his / her request, and
Since it is necessary to set the binding holes in the hopper of the printing apparatus with their binding hole positions aligned so as to match the desired binding margin, there is a problem in that the amount of work and load on the user side is large.

The present invention automatically recognizes the size of the printing paper, the conveying direction of the printing paper, and the position of the binding hole of the printing paper on the printing apparatus side, and automatically performs the binding margin intended by the user so as not to overlap the binding hole. It is an object of the present invention to provide a print control device which is modified so as to perform printing while correcting the position, thereby reducing the amount of work and the burden on the user side.

[Means for solving the problem]

Means adopted by the present invention to solve the above-mentioned problem will be described with reference to FIG. FIG. 1 is a block diagram showing the basic configuration of the present invention.

In FIG. 1, reference numeral 10 denotes a printer mechanism which includes a hopper 12 for storing printing paper 11 therein, a paper transport unit 13 (13A, 13B) for transporting the printing paper 11, and printing for performing one-sided or two-sided printing on the printing paper 11. The unit 14 includes a mechanism such as a stacker 15 that stores the printed printing paper 11 and performs one-sided or two-sided printing on the printing paper 11 that has been cut into a fixed size.

The present invention further includes a binding hole sensor section in the printer mechanism section 10.
A binding hole 16 is provided to detect a binding hole provided in the transported printing paper 11 and generate a binding hole detection signal corresponding to the paper size and the binding hole position. Since the binding holes of the printing paper are defined by the respective paper sizes, for example, a plurality of sets of binding hole sensors are provided in accordance with the binding hole positions of the printing paper of each size, or a movable binding hole sensor is provided. Is moved in accordance with the sheet size, thereby detecting the binding hole.

Reference numeral 20 denotes a printer control unit which controls the operation of each unit in the printer mechanism unit 10.

In the printer control unit 20, a binding hole position detection unit 21 designates a binding hole position corresponding to the paper size of the transported printing paper 11 based on a binding hole detection signal input from the binding hole sensor unit 16. To generate binding hole position information.

A print position correction unit 22 corrects the print position to a position that does not overlap the binding hole position based on each information of the printing paper size and the binding hole position, and develops the print data so as to be in a designated binding method. The print position correction information to be generated is generated.

Reference numeral 23 denotes a printing control unit which controls the printing operation of the printing unit 14 and moves the printing position based on the printing position correction information input from the printing position correction unit 22 to perform printing.

(Operation)

The user sets printing paper 11 having a required paper size and a binding hole in the hopper 12 of the printer mechanism unit 10. The hopper 12 detects the paper size and notifies the printer control unit 20 of it.

When the printing paper 11 is set on the hopper 12, the binding hole position direction may be arbitrary. That is, even when the binding margin is right (or left) binding, the binding hole position at the time of setting the printing paper may be any position on the right or left. Even when the binding hole position of the binding margin is above or below, the binding hole position at the time of setting the printing paper may be an arbitrary upper and lower position. It is desirable from the viewpoint of print processing efficiency to align the binding hole positions on one side, but they may not be aligned.

On the other hand, the host computer of the printing apparatus (not shown,
According to the print information registered in advance by the user, the instruction indicates whether the print format is one-sided printing or two-sided printing, and the binding margin of the print result is left binding, right binding, top binding, or bottom binding. Is instructed to the printing apparatus.

The printer control unit 20 of the printer device causes the printer mechanism unit 10 to perform one-sided or two-sided printing according to an instruction from the HOST.

The printer mechanism 10 is the first printing paper from the hopper 11
11 and take out the binding hole sensor 16 by the paper transport unit 13B.
To the side.

The binding hole sensor unit 16 detects a binding hole provided on the conveyed printing paper 11, generates a binding hole detection signal corresponding to the paper size and the binding hole position, and outputs the signal to the printer control unit.
This is sent to the 20 binding hole position detection units 21.

The binding hole position detection unit 21 generates binding hole position information indicating a binding hole position corresponding to the paper size of the transported printing paper 11 based on the input binding hole detection signal, and corrects the printing position. Send to part 22.

The print position correction unit 22 corrects the print position to a position that does not overlap with the binding hole position based on the paper size of the transported printing paper and the binding hole position information, and performs the specified binding method. The print position correction information for expanding the print data is created and sent to the print control unit 23. This print position correction information is used, for example, to correct the print position left or right or up and down so that the print content is located at the center of the binding hole position and on the opposite side of the paper edge, and to perform printing in the designated binding method. This is information for expanding data.

The printing control unit 23 controls the printing operation of the printing unit 14 and moves the printing position based on the printing position correction information input from the printing position correction unit 22 to perform printing.

When the printing paper 11 is set in the hopper 12, if the binding hole position direction that matches the designated binding margin and the binding hole position direction that is different are set unequally, the binding hole position differs. Those are assembled such that the print data development direction and the print data do not overlap the binding holes so as to match the binding margin specified by the print position assembly unit 22 provided in the printer control unit 20 (for details, refer to Section).

In the case of double-sided printing, after printing on the front side by the above-described method, the printing paper is reversed by the paper reversing mechanism and the back side is similarly printed.

When the designated one-sided printing or two-sided printing is completed, the printed printing paper is stacked on the stacker 15.

As described above, the printing paper size and
By automatically recognizing the binding hole position in the transport direction of the printing paper, it is possible to perform the printing by automatically correcting the position so that the binding margin does not overlap with the binding hole intended by the user.

This makes it possible for the user to create print data without being aware of the binding hole position, thereby simplifying the user's print data creation work and having compatibility with print data for print paper without binding holes. Can be made.

In addition, if the binding hole sensor for detecting the binding hole is configured using a movable sensor, the configuration of the binding hole position detection unit can be greatly simplified.

25 is the host interface section (hereafter referred to as the HIF section)
Then, reception processing of a command or print data from the HOST (not shown) is performed.

A main control unit 26 manages the operation of each unit in the printer control unit 20 and also manages the operation of the entire printer device.
Therefore, the main control unit 26 also shares the functions of the binding hole position detection unit 21, the print position correction unit 22, and the print control unit 23.

(B) Operation of Embodiment The operation of the embodiment during single-sided printing and double-sided printing will be described with reference to the processing flowchart of FIG. 3 and the processing steps.

The user sets printing paper 11 having a desired paper size and a binding hole on the hopper 12 before starting printing.
The hopper 12 detects the size of the set printing paper and sends it to the mechanism control unit 24. The mechanism control unit 24 sets this paper size to MS
It is set in the T register 241 and managed. The main controller 26 refers to the contents of the MST register 241 to recognize the size of the set printing paper 11.

On the other hand, the HOST (not shown) determines whether the print format is one-sided printing or two-sided printing according to print information registered in advance by the user, and determines whether the binding margin of the print result is left binding,
A command for instructing right binding, top binding, or bottom binding is issued to the printer device.

The HIF unit 25 of the printer receives a command from the HOST, decodes the command, and sends it to the main control unit 26.

The main control unit 26 instructs each print control unit 23, the mechanism control unit 24, and the like according to the print format (single-sided or double-sided printing) and the binding margin specified by the HOST to start the printing process. Less than,
The printing operation of the embodiment will be described separately for single-sided printing and double-sided printing.

(B-1) operation process S ₁ main control unit 26 of the single-sided printing, print format instructed by the HOST is determined whether the duplex printing (process S _1).

At a printing start, since the printing paper from the hopper 12 is not being fed, "NO" when the single-sided printing in the process S ₁
Is determined.

If it is determined as "NO" in the process S ₂ process S _1, the main controller 26
The mechanism controller 24 controls the hopper 12 and the sheet transport unit 13B to take out the first print sheet 11 from the hopper 12 and transport it to the binding hole sensor unit 16 side.

Note that the main control unit 26, upon completion of the command receiving process,
The host requests the HOST to transmit the print data, converts the transmitted print data into each character pattern to be printed, and develops it on a bitmap memory (not shown).

Processing S ₃ binding hole sensor unit 16 detects the binding holes are provided on the printing paper 11, and generates a binding holes detection signal corresponding to the paper size and binding hole located, and sends a binding hole position detector 21 (For details on the binding hole detection method and the binding hole detection signal,
This will be described in detail in the following section (C)).

The binding hole position detection unit 21 generates binding hole position information indicating a binding hole position corresponding to the paper size and the paper transport direction of the printing paper 11 based on the input binding hole detection signal, and corrects the printing position. Send to part 22.

Processing S ₄ print position correcting unit 22, based on pre-designated sheet size information from the binding hole position information and the main control unit 26 which is input, to correct the print position to a position that does not overlap with the binding hole position, and designated The print position correction information for expanding the print data so as to perform the binding method is created and sent to the main control unit 26.

The main control unit 26 develops each character pattern of the print data sent from the HOST on a bitmap memory (not shown), but the binding hole position information in the input print position correction information is instructed by the HOST. When it is confirmed that the position matches the specified binding hole position, the print content expanded in the bitmap memory is corrected to the position indicated by the print position correction information, and the print content is redeployed in the bitmap memory. 23 and
Instructs MCC24 to start printing.

Note that the binding hole position when the printing paper 11 is set on the hopper 12 does not always coincide with the binding margin position, and may be set at a position opposite to the binding margin position. In this case, the binding hole position specified by the binding hole position correction information is opposite to the binding margin position specified by the HOST. At this time, the main control unit 26
Develops print data on a bitmap memory in the main control unit 26 based on the print position aggregation information from the print position aggregation unit 22, thereby matching the closing hole position of the printing paper 11 with the binding margin position. .

Also, the binding hole position of the printing paper 11 may be sent directly from the binding hole position detection unit 21 to the main control unit 26 instead of being included in the print position correction information.

When instructed to start printing by the main control unit 26, the print control unit 23 takes out the print data expanded on the bitmap memory in the main control unit 26 and controls the data printing unit 141 of the printer mechanism unit 10. To print on the printing paper 11.

As a result, the printing position is moved in accordance with the paper size, printing direction, and binding hole position, and single-sided printing is performed so that the print content does not overlap the binding hole.

Hereinafter, repeated processing of the processing S ₁ to S _4, one-side printing of second and subsequent sheets is performed.

(B-2) Operations at Duplex Printing Processes S ₁ and S _{5 The} main control unit 26 determines whether the print format specified by the HOST is duplex printing (process S ₁ ).

When a double-sided printing, the printing performed by the print control unit 23 determines whether a reverse printing (process S _5).

At a printing start, since the printing paper from the hopper 12 is not being fed, it is judged as "NO" in the process S _5.

Processing _{S 2, S 3, S 4} , S 1, when it is determined "NO" in S ₅ process S ₅ is performed the process S ₂ to S ₄ described above, the first sheet of printing paper 11 is hopper The paper is fed from the printer 12 and printed on the front side of the paper so that the position of the paper is corrected so as not to overlap the binding hole position.

When printing on the front side is completed, the print control unit 23 is instructed,
The paper reversing mechanism 142 reverses the printing paper 11. Then, S ₁ the following processing is resumed again. Now, in the process S ₁ and S _2, both the main control unit 26 determines "YES".

If it is determined as "YES" in the process S ₆ process S _2, the main control unit 26
Instructs the print control unit 23 to take out the inverted printing paper from the paper reversing mechanism unit 142 and set it so that the back side is printed.

Binding hole position and the printing position correction amount of the processing S ₇ inverted print paper 11 is obtained by inverting the binding hole position and the printing position correction amount determined by the surface side. Therefore, the main control unit 26
It is to keep the binding hole position and the print position correction information of the surface side, to calculate the binding hole position and the printing position correction amount of the back side as a value obtained by inverting it (processing S _7).

Processing S ₄ main control unit 26, re the rear surface bitmap memory to correct the position indicated by the print position correction information obtained printing contents developed in the backside bit map memory in the process S ₇ It is developed and printed on the back side in the same manner as the front side.

In the same manner, it is repeated processes S ₁ to S ₇ described above,
Double-sided printing of the second and subsequent sheets is performed.

As a result, the printing position is moved according to the paper size, the printing direction, and the binding hole position, and double-sided printing is performed so that the print content does not overlap the binding hole.

The AND circuit 254 generates an AND output (lower binding hole position detection signal L) of the upper binding hole sensor U and the lower binding hole sensor 1 inverted by the NOT circuit 251.

When the paper size is A5, the upper and lower binding hole sensors u and l
Are the positions of the binding hole sensors e and f in FIG. 4, and the upper and lower binding hole position detection signals U and L at that time are the upper and lower binding hole position detection signals E and F of A5.

When the paper size is B5 / B4, the upper and lower binding hole sensors u and l are at the positions of the binding hole sensors g and h in FIG. 4, and the upper and lower binding hole position detection signals U and L at that time are the upper and lower positions of B5 / B4. These become the binding hole position detection signals G and H.

When the paper size is A4 / A3, the upper and lower binding hole sensors u and l are at the positions of the binding hole sensors i and j in FIG. 4, and the upper and lower binding hole position detection signals U and L are A4 / A3. It becomes an upper and lower binding hole position detection signal.

FIG. 9 (B) summarizes the above results as a straightforward value table.

In this way, by using the pair of movable upper and lower binding hole sensors u and l shown in FIG. 8, the configuration of the binding hole position detection circuit in the binding hole position detection unit 21 can be greatly simplified.

Although the embodiments of the present invention have been described above, the embodiments of the present invention are not limited to these embodiments.

For example, in the above-described embodiment, the result of the binding hole sensor is referred to each time printing is performed. However, the result is referred only when the printing paper is set on the hopper, and thereafter, when the size of the printing paper is changed. Or if the binding position of the paper is different from the printing paper printed immediately before,
Since it is not necessary to refer to the result of the binding hole sensor every time printing is performed, the printing processing speed can be improved.

〔The invention's effect〕

As described above, according to the present invention, the following effects can be obtained.

(A) As described above, the printing apparatus automatically recognizes the size of the printing paper and the position of the binding hole with respect to the transport direction of the printing paper so that the binding margin intended by the user does not overlap the binding hole. Printing can be performed with the position automatically corrected.

(B) Since the user can create print data without being aware of the binding hole position, it simplifies the user's print data creation work and has compatibility with print data for print paper without binding holes. Can be made.

(C) The configuration of the binding hole position detection unit can be greatly simplified by configuring the binding hole sensor unit that detects the binding hole using a movable sensor.
