Description

[Detailed Description of the Invention] This invention provides a passbook printing method, more specifically,
The present invention relates to a dot-type character printing method for printing a plurality of special characters within the printing range of one general character in a bankbook or the like.

In the conventional dot-type character printing method, only one character can be printed within the printing range for one character. FIG. 1 shows an example of printing on a part of a bankbook. In the passbook,
Printed fields such as transaction date, bank number, deposit amount, payment amount, balance, and other information are arranged horizontally, and each transaction information is printed in one horizontal row in each of these fields. Since the dates 5, 6, -, 1, -, and 1 are each one character, the conventional printing method sequentially prints them within the range of one character by moving the print head horizontally. It will be printed. However, store number 123 consists of three characters arranged in the vertical direction and is printed within the range of one character, so it is difficult to print each character 1, 2, and 3 using the conventional printing method. Therefore, it is not possible to print as shown in FIG. Conventionally, this three-digit number arranged in the vertical direction was treated as one character, and its print pattern data was stored in advance in a memory, and printed by reading it out. Therefore, when printing 3-digit numbers arranged vertically, it was necessary to store printing pattern data for 1000 types of numbers from 000 to 999 in memory. , there was a problem that the memory capacity had to be increased.

SUMMARY OF THE INVENTION An object of the present invention is to provide a passbook printing method that can print a plurality of characters within a printing range for one character, and that requires less memory capacity to store character print pattern data. do.

In this specification, each term is defined as follows. The direction in which the print head moves is horizontal, and the direction perpendicular to the horizontal direction on the paper surface on which printing is performed is vertical. Characters that are printed once within the printing range of the print head, such as the numbers representing the date shown in Figure 1, are general characters; The characters printed are called special characters.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 2 shows a schematic configuration of the printing device. The printing device is controlled by a central processing unit (CPU) 10 for printing control.
10 is ROM1 that stores the execution program
1, a RAM 12 for storing various data, and a character generator 13 for storing a large number of print character pattern data. The main CPU 30 controls the entire system including the printing device, and print information is sent to the main CPU 30.
is sent to CPU10.

Line feed motor 16 is for paper feeding, and space motor 17 is for moving print head 25 laterally. These motors 16 and 17 are controlled by a motor control circuit 15. The motor drive command from CPU10 is
It is decoded by the decoder 14 and input to the control circuit 15. A print command from the CPU 10 is sent to a decoder 21, decoded here, and input to a print control circuit 22. The print pattern data read out from the RAM 12 or the character generator 13 is temporarily stored in the buffer register 23, and is sent to the drive circuit 24 according to a command from the control circuit 22, and the print head 25 is moved in accordance with this data. The dot pin solenoid is activated.

In this example, the character is 20 dots tall and 20 dots wide.
Represented by 30 dots. This 20 x 30 dot area is the printing range. FIG. 3 shows the arrangement of the dot pins 26 that make up the print head 25.
There are 20 dot pins 26, and these 20 pins 2
6 are arranged in two vertical rows in a staggered arrangement with an interval of half a dot. Each of these columns is called a left column and a right column. Also, from the top to the bottom of Figure 3, the first row ~
Add line 20 and line number. The left column is the odd row, and the right column is the even row.

FIG. 4 shows part of the contents of the RAM 12. The RAM 12 includes an area for storing print information (print character string) sent from the main CPU 30, an area for storing pattern data of the first to third digits of special characters read from the character generator 13, A storage area for logical OR pattern data of the first and second digits and an area for storing final print pattern data of special characters are provided. The print character string is composed of codes representing characters to be printed arranged in the order in which they should be printed. Of course, the character code also indicates whether the character is a general character or a special character.

FIG. 5 shows an area in the character generator 13 in which pattern data of special characters is stored. In this embodiment, the special characters are numbers and are printed in three digits in the vertical direction within one printing area. Inside the character generator 13, the lower side of the special characters arranged in the vertical direction is the first digit.
Thirty types of pattern data representing special characters from 0 to 9 are stored in advance for each digit, with the middle part being the second digit and the upper part being the third digit. The storage location of these pattern data is
In this example, addresses from 80 to 9D are assigned. Also, these pattern data are 18×30
Consists of bits.

The pattern data at address 81 is illustrated in FIG. The data corresponding to each of the 20 dot pins 26 are assigned row numbers from the 1st row to the 20th row. Further, column numbers from the 1st column to the 30th column are assigned to the data columns from the left. The 2nd to 7th lines (upper side) represent the special character in the 3rd digit, and the 8th to 13th lines (middle part)
represents the special character in the second digit, and the 14th line~
The 19th line (bottom) represents the special character in the first digit. Since the pattern data at address 81 is for printing only the special character in the first digit, a combination of data codes 1 and 0 representing special character 1 is arranged in the 14th to 19th lines. Data code 0 indicating no printing is arranged in the other rows. Similarly address 82-8
9, the 14th to 19th lines consist of combinations of data codes 1 and 0 representing special characters 2 to 9, and the other lines consist only of data codes 0. In addition, the pattern data at addresses 8B to 93 for printing special characters in the second digit consists of a combination of data codes 1 and 0 representing special characters 1 to 9 in the 8th to 13th lines, and consists of only data code 0. Address 95~ for printing special character in 3rd digit
The 9D pattern data consists of a combination of data codes 1 and 0 representing special characters 1 to 9 in the second to seventh lines, and only data codes 0 in the other lines. When printing special characters, the 1st and 20th lines are not printed.

FIG. 6 shows how pattern data is synthesized for printing a combination of special characters, in this example 123, and FIG. 7 shows the procedure for pattern data synthesis. Main
The character codes of the print character string transmitted from the CPU 30 and stored in the print information storage area in the RAM 12 are read out one by one, and it is checked whether the general character is a special character or not (step 41). If the location where a special character is to be printed, such as the store number on a bankbook, is determined in advance, the steps can be taken from the position data of the print head 25.
41 determinations may be made.

Corresponding to a character code, the address of the character generator 13 where the pattern data of that character is stored is fixedly assigned in advance at the time of program design. In the case of a general character, a corresponding address is determined from the character code, pattern data is read from that address, and printing is performed based on this data. In the case of a special character, the first
The address of the character generator 13 corresponding to the special character in the digit is determined (step
42), the pattern data for printing the first digit special character is then read out according to the address, and the first digit pattern data in the RAM 12 is read out.
Stored in the data area (step 43).
Similarly, the addresses of the special characters in the second and third digits are determined (steps 44, 46);
The pattern data of those characters are read out from the character generator 13, and RMA1
The data are stored in the second and third digit pattern data areas of No. 2, respectively (steps 45 and 47).

Next, the logical sum of the pattern data of the first and second digits stored in the RAM 12 is calculated for each column (step 48), and the result is the logical sum of the first and second digits of the RMA12. Stored in the pattern data area (step 49). The above-described logical sum operation is repeated for all 30 columns (step 50). The special character of the first digit is 100 and the special character of the second digit is 020, so
The character data obtained as a result of these logical sums is 120. Next, this logical sum pattern
The logical sum of data and 3rd digit pattern data is 1
Calculations are performed for each column (step 51), and the results are stored in the final print pattern data area (step 53). When this OR operation is completed for all 30 columns, the final print pattern data is obtained (step 53). By performing a logical sum operation on the logical sum data 120 and the third digit special character 003, pattern data 123 is finally obtained. This final print pattern data is shown in FIG.

This final print pattern data is transferred from the RAM 12 to the buffer register 23 and sent to the drive circuit 24 based on the print command, and the solenoid of the dot pin 26 of the print head 25 is controlled and driven based on this data. Ru. In this printing operation, the print head 25 is moved half a bit by the motor 17, and at each printing position the dot pins in the left column are driven and controlled by the data corresponding to that column, followed by the dot pins in the right column. The dot pins are driven and controlled by the data corresponding to that column. In this way, a three-digit special character is printed within the printing range of the print head 25.

With conventional printing methods, 1000 types of printing pattern data were required, but in this example, 30 types of printing pattern data were required.
Since it is sufficient to store each type of print pattern data in the character generator, the memory capacity is extremely reduced.

In this example, three
Although an example of printing a number of digits is shown, the number of digits is of course not limited at all. Furthermore, although a dot-type impact printer is shown in the above embodiment, the present invention can also be applied to a dot-type thermal printer with a thermal head, and can also be applied to other types of dot-type printing devices. be.

As explained in detail above, the present invention divides the printing range for one general character into multiple digits in the vertical direction in a part of the line of a general character that is printed across multiple characters in the horizontal direction. To provide a passbook printing method for printing a plurality of digits of special characters arranged in the vertical direction so that each digit divided into a plurality of digits in the direction is arranged with a horizontally flipped special character. In this invention, printing pattern data of a special character consisting of a collection of data codes representing one overturned special character within the range of the relevant digit and not being printed in the range of other digits is provided for each digit. For each type, the number of types used is stored in memory in advance. Then, when printing of a special character is commanded, the print pattern data of the special character corresponding to the given multi-digit character code is sequentially read from the memory for each digit, and then these read print patterns are By logical sum operation of data, final print pattern data that can print multiple digits of horizontally flipped special characters is created within the printing range of one general character, and the print head is controlled by this final print pattern data. are doing. Therefore, even if the number of combinations of special characters for each digit is large, the number of special characters for each digit that are basic elements is small, so the storage capacity of the memory that functions as a character generator can be reduced. . Furthermore, in a part of the line of a general character that is printed across multiple characters in the horizontal direction, a special character with multiple digits horizontally arranged vertically within the printing range of one general character is printed at the same time as the general character. can do.
