Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an A-plate / B-plate printer which can print, for example, both A-plate and B-plate cut sheets.

[0002]

2. Description of the Related Art Conventionally, in Japan, the B plate is often used as the size of printed matter. However, foreign printed matter is version A, and uniformized sizes of printed matter are being promoted in order to improve white color productivity.

It has been pointed out that the office work efficiency in Japan is lower than that in foreign countries. One of the reasons for this is that the forms used by Japanese companies and government agencies are mixed A and B versions, for example A4. It is mentioned that the plate and the B4 plate or the B5 plate are mixed and used. As a result of such mixing, inefficiencies have arisen, such as the need for two types of office equipment and fixtures, A type and B type, when filing documents.

In order to improve this inefficiency, it has been decided that documents used in government offices will be unified in A4 version in the future, and the previously used B4 or B5 forms will be A4.
Is being changed to.

However, from the viewpoint of resource saving, it is not allowed to dispose of B4 size paper which has already been purchased at the same time as switching to the A4 system. It is also possible to switch all at once when the B4 paper runs out, but in companies with multiple offices, the paper runs out at different times, so we can move smoothly to A4 forms. Measures are required.

FIG. 6 shows a conventional printer device for both A and B versions.
Will be described. In FIG. 6, 30 is a printer device, 31 is a paper cassette, 32 is a paper size detector, and 3 is a paper size detector.
3 is a development position table, 34 is a print data holding unit, 35
Is a paper comparison unit, 36 is a bitmap memory expansion unit, 37
Is a bitmap memory, 38 is a search unit, and 39 is a multiplexer. In the figure, the expansion position table 33 to the bit map memory 37 are described as being outside the printer device 30, but in reality, they are all inside the printer device 30, and these are shown in order to explain the state of each part in an easy-to-understand manner. It is listed outside.

In the print data holding section 34, print data 34-1, which is data to be printed on a form, and paper numbers 34-2, such as A4 and B4, on which this should be printed are described. The printer device 30 is equipped with a paper cassette 31 that stores cut paper.
0 indicates that the paper size is detected by the paper size detector 32.
The paper size inside is detected.

In the expansion position table 33, the print data 3
Coordinate positions indicating the developed position when 4-1 is expanded on the bit map memory 37 are entered in correspondence with the left edge, the upper edge, the right edge, the lower edge and the sheet number indicating the sheet size.

Since the paper cassette 31 is constructed for each paper size, when the paper cassette 31 is set in the printer device 30, the paper size detecting section 32 is used.
Checks the paper cassette 31 to detect the cut paper size, and the paper comparison unit 35 and the multiplexer 3
This is notified to the search unit 38 via 9.

On the other hand, in the paper comparison unit 35, from the print data holding unit 34, the paper number 3 attached to the print data 34-1
4-2 is applied, and when the paper size of the paper cassette 31 output from the paper size detection unit 32 matches, the paper comparison unit 35 outputs a match signal, and at that time, the search unit 38 outputs the paper. The entry in the expansion position table 33 corresponding to the number is searched, and the bitmap memory expansion unit 36 causes the print data 3 to be output based on the left end, upper end, right end, and lower end data output from the expansion position table 33.
4-1 is expanded in the bit map memory 37, and the predetermined printing is performed on the cut paper stored in the paper cassette 31.

However, as a result of the comparison in the paper comparison unit 35, when the paper number 34-2 accompanying the print data 34-1 and the paper number of the paper cassette 31 output from the paper size detection unit 32 are different, the paper comparison is performed. The section 35 notifies the upper mechanism of this difference in paper size, and is controlled so that the wrong paper is not printed.

When the operator is informed of the difference in the paper size, the operator stores the paper data in the paper cassette 31.
The sheet cassette of the sheet number 34-2 attached to the sheet No. 1 is replaced, and processing is performed so that the coincidence signal is output from the sheet comparison unit 35.

[0013]

In such a conventional apparatus, when it is required to print the print data of A4 on the paper of B4 in order to save the paper, the operator operates the switch, for example. A control signal is output to invalidate the comparison operation of the paper comparison unit 35, and the print data 3
Even if the paper number 34-2 associated with 4-1 does not match the paper number of the paper cassette 31 output by the paper size detection unit 32, the print data 34-1 is printed on the paper stored in the paper cassette 31.

In this case, since the paper number 34-2 attached to the print data 34-1 is transmitted to the search unit 38 via the multiplexer 39, the expansion position table 33 is searched based on this paper number 34-2. I will do so
For example, when printing A4 print data on B4 paper,
That is, when the sheet number 34-2 attached to the print data 34-1 is A4 and the sheet number of the sheet cassette 31 is B4, the developing position is A4, so the sheet is deviated to the left, right, up, or down. The print position is reached. Moreover, in order to stop the operation of the paper comparison unit 35, an erroneous operation of printing the print data of B4 on the paper of A4 is performed, and the form may be cut.

Therefore, an object of the present invention is to provide an A-version / B-version dual-purpose printer device in which the above problems are improved.

[0016]

In order to achieve the above-mentioned object, in the present invention, as shown in FIG.
1 is provided and the combination of the paper number attached to the print data and another paper number on which this print data can be printed is entered. For example, when the print data to be printed on the A4 paper number can be printed on the B4 cut paper, the paper number A4, the paper size, and B4 are registered as a pair in the special form table 11. In the case of FIG. 1, in addition to this, the special form table 11 is used when printing the print data of B4 on the cut paper of A3 and when printing the print data of B5 on the paper of A4.
Here is an example filled in.

A second development position table 6 in which the left end, the upper end, the right end, and the lower end, which indicate the printing positions on the cut sheet, are provided corresponding to the entries entered in the special form table 11, is provided.

Further, the printer device 1 holds print data including a paper size detector 3 for detecting the size of the cut paper stored in the paper cassette 2, print data 4-1 and a paper number 4-2 attached to the print data 4-1. Holding unit 4, first expansion position table 5 having the same function as the conventional expansion position table 33 shown in FIG. 6, bitmap memory expansion unit 7, bitmap memory 8, paper comparison unit 9, paper size error suppression unit 10, Expansion position table switching unit 12, search unit 13, 1
4, 15, 16 and the like are provided.

[0019]

Operation: The print data 4-1 is attached to the paper number 4
-2, for example, when printing print data for A4 on A4 paper, the paper size error suppression unit 10 and the expansion position table switching unit 12 are shown in FIG.
It is in the solid line state shown in.

First, referring to the special form table 11, the combination of the paper number 4-2 attached to the print data 4-1 and the paper number of the paper cassette 2 notified from the paper size detecting section 3 is the special combination. It is detected whether or not it is registered in the form table 11. For example, it is checked whether or not a combination of paper numbers A4 to A4 is registered. However, since such a combination is not registered, the paper size error suppression unit 10 and the expansion position table switching unit 12 are
The solid line state shown in FIG. 1 remains.

Therefore, the paper comparison unit 9 outputs the paper number 4-2 from the print data holding unit 4 to the print data 4-1.
And the paper cassette 2 output from the paper size detection unit 3.
The printer device 1 operates by notifying that the paper number indicating the paper size of No. 1 is matched.

At this time, the retrieval unit 13 accesses the first expansion position table 5 and outputs the data of the left end, the upper end, the right end and the lower end of the first expansion position table 5 corresponding to the sheet number to the expansion position table switching unit 12. It is transmitted to the bit map memory expansion unit 7 via. Based on this, the bit map memory expanding section 7 expands the print data 4-1 into the bit map memory 8, and the predetermined printing is performed on the cut paper stored in the paper cassette 2.

However, as a result of the comparison in the paper comparison unit 9, when the paper number 4-2 accompanying the print data 4-1 does not match the paper number of the paper cassette 2 output from the paper size detection unit 3, the paper comparison unit Reference numeral 9 notifies the printer device 1 of the difference in paper size, and the printer device 1 notifies the operator of this difference by displaying or the like. When the operator is notified of the difference in the paper, the operator sets the paper cassette 2 to the print data 4-1.
Will be replaced with a paper number that matches the paper number 4-2 attached to.

By the way, when printing the print data of A4 on the paper of B4, the paper cassette 2 for B4 is set, so that the paper number 4-attached to the print data 4-1 is set.
2 indicates A4, and the paper number output by the paper size detection unit 3 indicates B4. As a result of referring to the special form table 11, this combination of A4-B4 is registered, so this time suppressing the paper size error. A coincidence signal is applied to the unit 10 and the form position table switching unit 12, and the connection state of these is controlled to be switched to the dotted line state.

As a result, the paper comparing section 9 receives the same input paper number, for example, B4, which is output from the paper size detecting section 3 as the two input signals, so the paper comparing section 9 outputs a coincidence signal.

At this time, the second expansion position table 6 is read in conjunction with the special form table 11 and, for example, when the combination matches in the first line of the special form table, the first line is read, This is transmitted to the bitmap memory expansion unit 7 via the expansion position table switching unit 12.

In the first row of the second expansion position table, A4
When the print data of B is printed on the sheet of B4, the coordinate positions of the left edge, the upper edge, the right edge, and the lower edge of the B4 sheet are entered.
Is expanded in the bitmap memory 8 by the bitmap memory expansion unit 7, and the print data of A4 can be printed at a predetermined position on the paper of B4.

Even if the print data of B4 is to be printed on the print paper of A4, such a combination is not described in the special form table 11 and therefore is not erroneously printed.

The bit map memory expansion unit 7 expands the print data 4-1 in the bit map memory 8 based on the expansion position read from the first expansion position table 5 or the second expansion position table 6.

The bitmap memory 8 is used for the printer device 1.
The bit information to be printed on the cut paper stored in the paper cassette 2 is expanded by. The paper comparison unit 9 is for comparing whether the paper numbers, paper sizes, and the like input from the two input ends match.

The paper size error suppression unit 10 uses one of the data input to the paper comparison unit 9 as the paper number 4-2 attached to the print data 4-1 or the paper output from the paper size detection unit 3. It is something to choose whether to make it size. Initially, the paper number 4-2 is selectively output to the paper comparison unit 9, but as will be described later, when the combination of the paper number and the paper size registered in the special form table 11 in advance, the paper size detection unit 3 is used. The paper size input from is selected and output to the paper comparison unit 9.

The special form table 11 includes print data 4-
1 shows combinations that can be printed by the printer device 1 when the paper number associated with 1 and the paper size of the cut paper stored in the paper cassette 2 set in the printer device 1 are different. FIG. 3B shows the details of the special form table 11 and shows an example of the size of N rows. For example, the paper number (1) on the first line is A4, the paper size (1) is B4, and the paper number (2) on the second line is B4.
And the paper size (2) is A3. Then, the special form table 11 and the second expansion position table 6 are searched in association with each row.

The printing position table switching unit 12 outputs the expansion position data for the bitmap memory 8 output from the first expansion position table 5 and the bitmap memory output from the second expansion position table 6 in conjunction with the special form table. The expansion position data for 8 are switched and output to the bit map memory expansion section 7. Initially, the expansion position data output from the first expansion position table 5 is selectively output, but when the combination of the paper number and the paper size registered in advance in the special form table 11 is used, the expansion position data is output from the second expansion position table 6. The output position data to be output is selectively output.

The retrieving unit 13 sequentially retrieves the paper size item in the first expansion position table 5, and the paper size detecting unit 3
It is to detect whether or not the paper size output from is registered in this.

The retrieval unit 14 sequentially retrieves the sheet number item in the special form table 11 to detect whether or not the sheet number associated with the print data 4-1 is registered therein.

The search unit 15 sequentially searches the paper size item of the special form table 11 in cooperation with the search unit 14, and determines whether the paper size output from the paper size detection unit 3 is registered therein. It is to detect that.

The search unit 16 reads each item of the second expanded position table in conjunction with the search unit 14, and reads the left end of the item.
The upper end, right end, and lower end data are output to the expansion position table switching unit 12.

The microprocessor 21 controls the printer device 1 and performs a control operation as shown in FIGS. 4 and 5, which will be described later. In the microprocessor 21, the combination of the paper number and the paper size obtained by searching the same line of the special form table 11 in cooperation with the search units 14 and 15 is the paper number 4-2 attached to the print data 4-1. When the paper size detected by the paper size detection unit 3 matches, the flag 22 is turned on. Based on this, the paper size error suppression unit 10 and the expansion position table switching unit 12 are each controlled to be switched to the dotted line state, and the paper size error suppression unit 10 instructs the paper comparison unit 9 to input the paper size input from the paper size detection unit 3. Is sent and the paper size error suppression operation is performed. Further, the expansion position read from the second expansion position table 6 is sent to the bitmap memory expansion unit 7.

Next, the operation of the embodiment of the present invention shown in FIG. 2 will be described with reference to FIG.
It will be described based on the flowchart shown in FIG. In FIG. 2, the print data 4-
1 and the paper number 4-2 are entered, the printer device 1
A start signal is sent from the upper mechanism to the. As a result, the printer device 1 is activated and the operation shown in FIG. 4 is performed.

(1) The paper comparing unit 9 detects the paper number 4-2 attached to the print data 4-1 and the paper size detecting unit 3 indicating the cut paper stored in the paper cassette 2 set in the printer 1. Compare the entered paper size.

(2) If the paper number and the paper size match in the paper comparison unit 9, the paper comparison unit 9 outputs a match signal to the microprocessor 21 of the printer device 1.

(3) As a result, the microprocessor 21
Causes the search unit 13 to sequentially search for the item of paper size in the first development position table 5 from the top. (4) The microprocessor 21 checks whether or not the paper size transmitted from the paper size detection unit 3 is detected in the first expansion position table 5 by this search of the search unit 13.

(5) When this paper size is detected in the paper size section of the first development position table 5, the microprocessor 21 develops positions on the same line as the detected paper size, that is, the left end and the top end. , The right end and the lower end are output, and these are sent to the bitmap memory expansion unit 7 via the expansion position table switching unit 12.

(6) The bitmap memory expansion unit 7 expands the print data 4-1 on the bitmap memory 8 based on the expansion position information. (7) The printer device 1 prints the print data expanded on the bitmap memory 8 on the cut paper stored in the paper cassette 2. After the printing is executed in this way, the microprocessor 21 reports the printing result to the higher-level mechanism, and the printing ends.

(8) In the above (4), when the paper size transmitted from the paper size detecting unit 3 is not detected from the first expansion position table 5, the microprocessor 21 reports an error to the upper mechanism and ends. To do.

(9) Further, in the above (2), when the comparison result of the paper number and the paper size in the paper comparing unit 9 does not match, the microprocessor 21 controls the search of the special form table 11. That is, the search units 14 and 15
The paper number and the paper size entered in the special form table 11 are sequentially read line by line, and these are output from the paper number 4-2 and the paper size detection unit 3 attached to the print data 4-1. It is searched whether it matches the specified paper size.

(10) If there is a matching item, the microprocessor 21 determines that this combination of paper number and paper size is printable, and turns on the flag 22. (11) Then, the microprocessor 21 switches the paper size error suppression unit 10 to the state of the dotted line, so that the paper size detection unit 3 is provided at each of the two input ends of the paper comparison unit 9.
Since the same paper size input from the above is input, the paper comparison unit 9 does not output the signal indicating the mismatch, but outputs the match signal.

(12) The microprocessor 21 also switches the expansion position table switching unit 12 to the state indicated by the dotted line. (13) As a result, the second developing position table 6 is read by the searching unit 16 that operates in cooperation with the searching units 14 and 15, and the developing position corresponding to the combination of the paper number and the paper size, that is, the left end, The upper end, the right end, and the lower end are sent to the bitmap memory expansion unit 7 via the expansion position table switching unit 12. As a result, (6),
The same processing as (7) is performed, and this time, not the expansion position information of the first expansion position table 5, but the second expansion position table 6 which is the expansion format suitable for the combination of the paper number and the paper size is read. Printing is performed based on the expanded position information.

(14) If there is no matching item in (10), the microprocessor 21 determines that printing cannot be performed with this combination of paper number and paper size, and reports an error to the host mechanism.

The operation of the second embodiment of the present invention will be described based on the flowchart shown in FIG. In FIG. 2, when the print data 4-1 and the sheet number 4-2 are written in the print data holding unit 4 from the upper mechanism, a start signal is sent from the higher mechanism to the printer device 1. As a result, the printer device 1 is activated and the operation shown in FIG. 5 is performed. In FIG. 4, the paper comparison unit 9 first operates, but in the second embodiment shown in FIG. 5, the special form table 11 is searched first.

(1) The microprocessor 21 first searches and controls the special form table 11. That is, the search unit 14
And 15 are linked, the paper number and the paper size entered in the special form table 11 are sequentially read line by line, and the paper number read from the special form table 11 is made to match the paper number attached to the print data 4-1. Then, it is searched whether or not the paper size read from the special form table 11 at that time matches the paper size notified from the paper size detection unit 3.

(2) As a result, the special form table 11
The combination of paper number and paper size read from is
It is determined whether or not the combination of the paper number 4-2 attached to the print data 4-1 and the paper size notified from the paper size detection unit 3 matches. That is, the microprocessor 21 determines whether or not there is a matching item in the special form table 11. If there is a matching item, it is determined that this combination of paper number and paper size is printable, and the flag 22
Turn on.

(3) Then, the microprocessor 21 switches the paper size error suppression unit 10 to the state of the dotted line, so that the two paper inputs of the paper comparison unit 9 are the same paper sent from the paper size detection unit 3. The size is input, and the paper comparison unit 9 does not output a signal indicating inconsistency but outputs a coincidence signal.

(4) Further, the microprocessor 21 switches the expansion position table switching section 12 to the dotted line state. (5) As a result, the search unit 16 that operates in conjunction with the search units 14 and 15 reads the second expansion position table 6 and expands the position corresponding to the combination of the paper number and the paper size, that is, the left end. , The upper end, the right end, and the lower end are sent to the bitmap memory expansion unit 7 via the expansion position table switching unit 12.

(6) The bitmap memory expansion unit 7 expands the print data 4-1 on the bitmap memory 8 based on the expansion position information. (7) The printer device 1 prints the print data expanded on the bitmap memory 8 on the cut paper stored in the paper cassette 2. After executing the printing in this way, the microprocessor 21 reports the printing result to the higher-level mechanism, and the printing ends.

(8) If there is no matching item in (2), the paper size error suppression unit 10 and the expansion position table switching unit 12 are not switched and are in the state shown by the solid line.
Therefore, the paper comparison unit 9 receives the paper number 4-2 attached to the print data 4-1 and the paper size detection unit 3 indicating the cut paper stored in the paper cassette 2 set in the printer device 1 or the input paper size. Compare with.

(9) If the paper number and the paper size match in the paper comparison unit 9, the paper comparison unit 9 outputs a match signal to the microprocessor 21. (10) As a result, the microprocessor 21 causes the search unit 13 to sequentially search the item of the paper size of the first expansion position table 5 from the first line, for example.

(11) The microprocessor 21 checks whether or not the paper size transmitted from the paper size detection unit 3 is detected in the first expansion position table 5 by this search of the search unit 13.

(12) The microprocessor 21 determines that the paper size transmitted from the paper size detection unit 3 is the first
When it is detected in the paper size section of the expansion position table 5, the expansion position information of the same line as the detected paper size, that is, the left end, the upper end, the right end and the lower end is output, and is output via the expansion position table switching unit 12. Then, these are sent to the bitmap memory expansion unit 7. As a result, (6),
The same process as (7) is performed, and printing is performed based on the expansion position information output from the first expansion position table 5 this time.

(13) In (11), when the paper size transmitted from the paper size detecting unit 3 is not detected in the paper size section of the first expansion position table 5, the microprocessor 21 is set to the upper mechanism. Report an error.

(14) Further, in (9), if the paper number and the paper size in the paper comparing unit 9 do not match, the paper comparing unit 9 reports an error to the upper mechanism.
It should be noted that this error report can also be made through the microprocessor 21.

According to the second embodiment of the present invention shown in FIG. 5,
Since the special form table 11 is searched first, when the paper number attached to the print data and the paper size of the cut paper stored in the paper cassette 2 are different, it is possible to print quickly.

In the above description, an example in which cut paper is used has been described, but the present invention is not limited to this.
