Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic desktop calculator with a printer, and more particularly to a printing device, numeric keys for inputting numerical values, and numeric information inputted by the numeric keys to a predetermined printing position. The present invention relates to an electronic desktop calculator with a printer (hereinafter referred to as a printer calculator) having an input device equipped with specific keys for printing.

In conventional printer calculators, a specific key with a name such as "Non-Add Key" and a "#" mark (hereinafter referred to as the "Non-Add Key") is provided on the keyboard as an input device, and pressing this key triggers input. There is a known device that has a function of printing the numerical information that has been generated, separated from the calculation data, in a left-aligned manner along with a "#" mark.

FIG. 1 shows the results of printing on roll paper using such a conventional printer calculator. In the print result shown in FIG. 1, the information printed with a "#" mark and aligned to the left is printed using the non-add key described above.

The above-mentioned non-add key printing function, as shown in #80.5.12 in the first line of Figure 1, is mainly provided to distinguish the calculation results printed by entering the date or product code related to the calculation. Many of these functions allow you to insert as many decimal points as delimiters in the sequence. This non-add key printing function is useful because it allows you to insert headings in calculations with limited type, but it can only be printed left-justified.
It also had the disadvantage of a narrow range of expression, such as not being able to include spaces within a number sequence. However, adding a space key or increasing the number of typefaces to solve this problem would lead to an increase in the size of the device, and it would be difficult to use a device like a printer calculator to type strings like a typewriter. doesn't make much sense either.

The present invention has been made in view of the above points, and an object of the present invention is to provide an electronic desktop calculator with a printer that has a simple and inexpensive structure and has a non-address key function with a wide range of expression without increasing the size of the device. do.

In order to achieve the above object, the present invention provides a printing means, an input means for inputting numerical information, an instruction means for instructing to print the numerical information inputted by the input means at a predetermined printing position, and the numerical information a detection means for detecting a break point in the middle; a means for replacing the numerical information of the entire line separated by the break point of the numerical information; and a specific character inputted at the beginning of the partial information in the line with a space; established,
A configuration is adopted in which the numerical information is printed on printing paper in a desired format in response to an instruction from the instruction means.

Hereinafter, the present invention will be explained in detail based on embodiments shown in the drawings.

FIG. 2 shows an embodiment of the printer calculator of the present invention. In the figure, what is indicated by reference numeral 1 is a keyboard equipped with numeric keys using a numeric keypad 11, and furthermore, on the keyboard 1 there are functions such as +, -, =, etc. key 1
The keyboard 1 is connected to a CPU (central processing unit) 2 via a data bus KBS. The CPU 2 is configured, for example, as a one-chip LSI, and includes a memory 21 for storing calculation data, an accumulator 22 for performing calculation processing, and a memory 22 for storing programs.
It consists of a ROM (read only memory) 23, flags 25, 26, 27 indicating the processing status, a stack pointer 28 that specifies the address of data stored in the memory 21, and a CPU 2.
It has a printer register 24 that stores information to be printed by the printer 3 connected to the printer. Also,
The CPU 2 is provided with a display device (not shown) using an LCD, an LED, or the like.

The processing operation of CPU2 in the above configuration is explained in the third section.
The process will be described in detail below with reference to the flowchart shown in FIG. 4 and the explanatory diagram shown in FIG. However, in the following explanation, when printing the date data "80.5.12" with 1 space before the month with 4 spaces from the left and a "#" mark (this is processing example A),
The operation will be explained by taking as an example the operation when the numerical sequence data "0046" and "#" mark are printed together (this will be referred to as processing example B). In the present invention, the above processing examples A and B are realized by treating numerical information of an entire line separated by decimal points and zeros added at the beginning of partial information within a line as spaces.
Therefore, the key input for processing example A is "000080,
05, 12#", the key input for processing example B is "0046
＃”.

First, in step S1 of FIG. 3, the stack pointer 28 is set to the initial value, and the first digit of the input data ("000080, 05, 12#" in processing example A, "0046#" in processing example B) is set to the initial value. Memory 2 to store
Specify address 1.

Next, in step S2, one of the above input data
The digit is transferred from the memory 21 to the accumulator 22, and then in step S3 it is determined whether or not this transferred digit is a decimal point. In both processing examples A and B, the first digit is 0 and is not a decimal point, so the process moves to step S7 to check whether the input data is complete. (If the process ends here, the process moves to step S9.) Since both process examples A and B have continuations, 1 is added to the stack pointer 28 in step S8 to designate the next digit.

By repeating the above operations, it can be determined that in processing example B, all "0046#" do not contain decimal points, but in processing example A, "000080, 05, 12#", they contain two decimal points (break points). Therefore, from step S3 to step S4, S at the 7th decimal point.
5. Move to loop S6.

In step S4, the state of the flag 25 indicating the presence of decimal point information is checked. Since the 7th digit in processing example A is the first decimal point, flag 25 is not set, so the process moves to step S5 and flag 25 is set.
is set and the process returns to step S7. Processing example A 10
When reaching the digit, there is already a decimal point at the 7th digit and flag 25 has been set, so the process moves from step S4 to step S6, and flag 26 indicating the presence of a second decimal point is set.

In the above steps S1 to S9, it is determined whether the decimal point is numerical data for calculation or comment data such as a date. If the data contains two or more decimal points as in processing example A, step S6 is performed. If it is determined that the data is not calculation data and does not contain a decimal point or contains only one decimal point, the process proceeds from step S7 to step S.
Move on to 9. In case of processing example B, since the decimal point is not included, steps S4, S5 and S6 are not passed, and flags 25 and 26 remain reset.

Next, in step S9, the flag 27 is set unconditionally. This flag 27 is for treating "0" as a space (not printing).

In the following step S10, a "#" mark is stored in the printer register 24, and in step S11, the stack pointer 28 is again set to the initial value and specifies the address in the memory 21 where the first digit of the input data is stored.

In the next step S12, the first digit of the input data ("0" in both processing examples A and B) is transferred to the accumulator 22, and in the following step S13, the state of the previous flag 26 is checked. In processing example A, since the input data includes two decimal points, the process moves from step S13 to step S14.

In step S14, it is determined whether the data is the decimal point in the accumulator 22 or not. Since the first digit of processing example A is "0", the process moves to step S15.
Check the status of flag 27. Since flag 27 remains set in step S9, step S15
The process moves to step S16, and the accumulator 22
Determine whether the data inside is "0" or not. Processing example A
Since the first digit is "0", the process moves to step S17, where the space code is transferred to the printer register 24, and the process moves to step S22, where it is determined whether or not the data is complete.

In processing example A, the first four digits are "0", so
The above operation is repeated four times while incrementing the stack pointer 28 by 1 in step S23, but when the fifth digit is "8", the data is "8" after passing through steps S12 to S15, so steps S16 to S18 are performed. After the flag 27 is reset in step S21, "8" in the accumulator 22 is transferred to the printer register 24.

If the 6th digit is "0", steps S12-S13-
The process moves to step S14, and since the flag 27 has been reset at the fifth digit, the process jumps to step S21.

When the decimal point appears at the 7th digit, it is time to step S.
14 to S19, the flag 27 is set again, and the decimal point code is stored in the printer register 24 in step S20, followed by step S21.
to move to.

Since the flag 27 is set for the eighth digit "0", the space code is transferred to the printer register 24 in the same way as for the first four digits.

By repeating the same process as described above, the print data based on the input data of processing example A is transferred to the printer register 2.
Transferred to 4. In processing example A, what is stored in the printer register 24 at the final stage of data transfer is "#★★★★80.★5.12" (★ is a space code).

When the data is completed, the process moves from step S22 to step S24, and the printing data stored in the printer register 24 is transferred to the printer 3, where printing is performed. A printing example of processing example A is indicated by reference numeral A in FIG. As shown in the figure, the dashed line "0" indicates the space, and the date comment is spaced 4 spaces apart, and 1 space is placed before "5".
Space has been added. Similarly, in the printing on the third line from the bottom in FIG. 4, the "0" at the beginning of the line and the "0" before the "3" are converted to spaces.

On the other hand, in processing example B, since the input data does not include a decimal point and the flag 26 is not set, the process moves directly from step S13 to step S21, and the data is transferred from the accumulator 22 to the printer register 24 digit by digit. Therefore, in processing example B, steps S12 to S13
~S21~S22~S23 are repeated to transfer all data from the accumulator 22 to the printer register 24, and finally the printer register 2
4 is stored with "#0046", and in accordance with this printing data, in step S24, the printer 3 performs left-aligned printing as in the prior art, indicated by the symbol B in FIG.

As described above, by adding "0" to the beginning of the numerical information of the entire line of input data separated by decimal points and the partial information within the line, the operator can print comments using the non-add key according to his/her preference. Printing can be done at the location.

In the above embodiment, the number "0" is used as an example of a specific character for specifying a space, but this specific character is not limited to this, and any character that can be provided on a calculator may be used. Of course. Further, the symbol attached to the non-ad key is not limited to "#", and other symbols may of course be used.

In addition, in the example shown above, when two or more decimal points are included as break points in the input information, the specific character is replaced with a space, but the setting regarding the number of decimal points is limited to the above two or more. You can increase the number to 3 or more, 4 or more by changing the flag setting without any trouble, or you can replace the specific character with a space when one or more is included.

As is clear from the above description, according to the present invention, there is provided a printing means, an input means for inputting numerical information, an instruction means for instructing to print the numerical information inputted by the input means at a predetermined printing position; Detection means for detecting breakpoints in numerical information, replacing the numerical information of an entire line separated by the breakpoint of the numerical information, and specific characters inputted at the beginning of partial information in the line with spaces. Since the numerical information is printed on printing paper in a desired format in response to an instruction from the instruction means, the numerical information can be easily and inexpensively expressed without increasing the size of the device. It is possible to provide an electronic desktop calculator with a printer that has a wide range of non-add key functions.
