Then, as shown in FIG. 10 (A11), when the [x] (multiplication) key is operated (step S12 (Yes)), the calculation data memory 22c (FIG. 3) corresponding to the current row number "06" Calculation data consisting of the displayed numerical data "5" and the operation data "x" input by the [x] (multiplication) key is stored in the memory area (see step S13).

Then, the symbol "x" of the input calculation data "x" is displayed on the display unit 12 (step S14).

Here, when it is determined that the print mode (ON) is in the state (step S15 (Yes)), as shown in FIG. Numerical data "5" and arithmetic data "x" stored correspondingly are printed on the recording paper P (step S16).

After that, as shown in FIG. 10 (A12), when the numerical data "110" which is the operand for the operand "5" is input (step S9 (Yes)), the current row The number is incremented by (+1) and updated to "07", and the input numerical data "110" is displayed on the display unit 12 in association with the line number "07" (step S11).

Then, as shown in FIG. 10 (A13), when the [=] (execution function) key 11c is operated (step S17 (Yes)), the input numerical data "110" and the [=] key 11c is stored in the memory area corresponding to the current line number "07" of the calculation data memory 22c (step S18).

Then, the current line number is incremented by (1) to be updated to "08", the series of calculation data "5×110=" stored in the calculation data memory 22c is calculated, and the total (calculation result) is obtained. Data "550" is displayed in association with row number "08". Also, the total (calculation result) data "110" is stored in the memory area corresponding to the current row number "08" of the calculation data memory 22c (step S19).

When it is determined that the print mode (ON) is in effect (step S21 (Yes)), as shown in FIG. The numerical data "110", the execution function data "=", and the total (calculation result) data "550" saved corresponding to the current line number "08" are printed on the recording paper P. (step S22).

After that, in order for the user to obtain a print copy including the payment amount data "360" which is the total (calculation result) data, the final deposit amount data "560", and the change data "200", see FIG. As shown in A14), when the [REPRINT] (saved data print) key 11e is operated (step S29 (Yes)), as shown in FIG. A stored data print start mark "...0..." indicating that the calculated data is printed is printed on the recording paper P (step S30).

Then, a series of calculation data stored in the calculation data memory 22c (see FIG. 3(B)) is read out, and as shown in FIG. 10(B4), "120+", "240=" ', '360*', '560', '200C=', '5x', '110=', and '550' (step S31).

As a result, immediately after inputting deposit amount data and temporarily calculating and displaying change data for payment amount data, which is total (calculation result) data corresponding to a series of calculation data, different deposit amount data is displayed again. Even if you enter numerical data (deposited amount data) for recalculating change data or numerical data for the next calculation, the numerical data that you input will be According to the line number provisional display processing (mode 1), it is displayed in association with the line number (temporary display) data "---" (or blank), so that the calculator 10A saves the input numerical data. It can be clearly shown that the destination is currently unknown.

Therefore, even when the change is calculated by inputting the deposit amount and then recalculating the change by repeatedly inputting a new deposit amount, it is possible to display a line number that is easy for the user to understand according to the recalculation operation. be possible.

In the case of the general calculator 10B instead of the printer-equipped calculator 10A, the processing related to printing among the calculation data display processing (steps S2, S3, S7, S8, S15, S16, S21, S22, S27 to S31/ 10 (A14) (B1 to B4)) are not provided, and other processes are the same.

FIG. 11 is a diagram showing the display operation according to the user's operation in the first embodiment (line number display mode "2", "3") of the calculation data display process. FIG. 11B shows a display operation corresponding to the line number display mode "2", and (B1) to (B13) of the figure show display operations according to the line number display mode "3".

(Line number display mode "2")
In the display operation according to the line number display mode "2" shown in FIGS. 11(A1) to (A13), the display according to the line number display mode "1" shown in FIGS. The display operation of the line number (temporary display) data when the numerical data is input immediately after the change data is once calculated and displayed ((A8) and (A10) in FIG. 11) differs from the operation.

That is, for the total (calculation result) data (payment amount data) "360" calculated as shown in FIGS. 11(A1) to (A5), as shown in FIG. (Steps S9 and S11), and then, as shown in FIG. 11 (A7), the [CHANGE] (change function) key 11d is operated (Step S23 (Yes)).

Then, the calculation result data "140" obtained by subtracting the payment amount data "360" from the numerical data (first numerical data) "500" as the deposit amount data is displayed as change data (first change data) (step S25), the deposit amount data "500" and the change function data "CHANGE" are stored in the memory area (see FIG. 3A) of the current line number "04", and the line number is increased by (+1). is updated to "05", and the change data "140", which is the calculation result data, is stored (step S26).

Here, as shown in FIG. 11 (A8), when the user (clerk) inputs the numerical data (second numerical data) "560" as the deposit amount again presented by the customer (step S9 (Yes) ), similar to the above, it is determined that the function operated by the user immediately before is the change function data "CHANGE", that is, immediately after the change is calculated (step S10 (Yes)), and the line number in FIG. A transition is made to temporary display processing (step SA).

In the line number temporary display process, if the current line number display mode is determined to be "2" (step A2 (Yes)), the current line number "05" is stored in the line number data/line number temporary display data memory 22d. " is (-1) and the row number (provisional display) data "04" is stored (step A4).

Then, although the current line number "05" is incremented by (1) and updated to "06", here, as shown in FIG. 11A8, the input numerical data (amount data) " 560" is displayed in association with the row number (provisional display) data "04" (step S11).

That is, the calculator 10A assumes that the input numerical data (second numerical data) "560" is deposit amount data for recalculating the change data, and assumes that the immediately preceding change data (second numerical data) 1 Change data) The line number (provisional display) data "04" to be overwritten with the deposit amount data is displayed by subtracting (-1) from the line number "05" which is the storage destination of "140".

Then, as shown in FIG. 11A9, when the [CHANGE] (change function) key 11d is operated (step S23 (Yes)), the function operated immediately before by the user is the change function data "CHANGE". , it is determined that the change has just been calculated (that is, the input of the [CHANGE] (change function) key 11d this time is a repeated input) (step S24 (Yes)).

Then, the current line number "06" is decremented by (-2) to be updated to "04" (step S24a), and the numerical data " The calculation result data (second change data) "200" obtained by subtracting the payment amount data "360" stored in the payment amount memory 22f from the payment amount data "360" from the payment amount memory 22f is re-used as the change data as shown in FIG. 11 (A9). is displayed (step S25).

Then, in the same manner as described above, as shown in FIG. 3B, the deposit amount data (second numerical data) "560" and the change function are stored in the memory area of the current row number "04" of the calculation data memory 22c. The data "CHANGE" is overwritten and saved, the line number is incremented by (1) to be updated to "05", and the change data (second change data) "200", which is the calculation result data, is overwritten and saved. (step S26).

Here, as shown in FIG. 11 (A10), when the user inputs the numerical data "5" as the operand of the next calculation (step S9 (Yes)), the change is calculated in the same manner as described above. 8 (step S10 (Yes)), and the process proceeds to the line number provisional display process in FIG. 8 (step SA).

Then, it is determined that the current line number display mode is "2" (step A2 (Yes)), and the current line number "05" in the line number data/line number provisional display data memory 22d (-1) is displayed. Number (temporary display) data "04" is stored (step A4).

Then, although the current line number "05" is incremented by (1) and updated to "06", here, as shown in FIG. (Temporary display) Displayed in association with data "04" (step S11).

That is, here again, the calculator 10A assumes that the input numerical data "5" is deposit amount data for recalculating the change data, and is the save destination of the immediately preceding change data "200". The line number (provisional display) data "04" obtained by subtracting (-1) from the line number "05" is displayed.

Then, as shown in FIG. 11 (A11), when the [x] (multiplication) key is operated (step S12 (Yes)), the calculation data memory 22c (FIG. 3) corresponding to the current row number "06" Calculation data consisting of the displayed numerical data "5" and the operation data "x" input by the [x] (multiplication) key is stored in the memory area (see step S13).

As a result, immediately after inputting deposit amount data and temporarily calculating and displaying change data for payment amount data, which is total (calculation result) data corresponding to a series of calculation data, different deposit amount data can be displayed. Even if the numerical data (deposit amount data) for re-inputting and re-calculating the change data or numerical data for the next calculation are input, the line number provisional display process ( According to mode 2), the input numerical data is assumed to be the deposit amount data for recalculating the change data, and the row in which the deposit amount data entered along with the calculation of the immediately preceding change data is saved is stored. It is displayed in association with the number (temporary display) data "04". Therefore, the calculator 10A can clearly indicate that the storage destination of the input numerical data is the storage destination to overwrite the deposited amount data for recalculation of the change data at the present time.

Therefore, even when the change is calculated by inputting the deposit amount and then recalculating the change by repeatedly inputting a new deposit amount, it is possible to display a line number that is easy for the user to understand according to the recalculation operation. be possible.

(Line number display mode "3")
In the display operation according to the line number display mode "3" shown in FIGS. 11(B1) to (B13), the display operations shown in FIGS. , the display operation of the line number (temporary display) data when numerical data is entered immediately after the change data is calculated and displayed (Fig. 11 (B8) (B10)) are different.

That is, for the total (calculation result) data (payment amount data) "360" calculated as shown in FIGS. 11(B1) to (B5), as shown in FIG. (steps S9 and S11), and as shown in FIG. 11(B7), the [CHANGE] (change function) key 11d is operated (step S23 (Yes)). ).

Then, the calculation result data (first change data) "140" obtained by subtracting the payment amount data "360" from the numerical data (first numerical data) "500" as the deposit amount data is displayed as the change data (step S25), the deposit amount data "500" and the change function data "CHANGE" are stored in the memory area (see FIG. 3A) of the current line number "04", and the line number is increased by (+1). is updated to "05", and the change data (first change data) "140", which is the calculation result data, is stored (step S26).

Here, in the same manner as described above, as shown in FIG. 11B8, when the user (clerk) inputs the numerical data "560" (second numerical data) as the deposit amount again presented by the customer (step S9 (Yes)), it is determined that the function operated immediately before by the user is the change function data "CHANGE", that is, immediately after the calculation of the change (step S10 (Yes)), and the line number in FIG. A transition is made to temporary display processing (step SA).

In the line number temporary display process, if it is determined that the current line number display mode is "3" (step A2 (No)), the current line number "05" is stored in the line number data/line number temporary display data memory 22d. ” (+1) to store the row number (temporary display) data “06” (step A5).

Then, although the current line number "05" is incremented by (+1) and updated to "06", here, as shown in FIG. 560" is displayed in association with the row number (provisional display) data "06" (step S11).

That is, here, regarding the input numerical data "560" (second numerical data), the calculator 10A assumes that it is numerical data input as an operand of the next calculation, and the immediately preceding change data The data "06" of the new line number (provisional display) obtained by (+1) the line number "05", which is the storage destination of the (first change data) "140", is displayed.

Then, as shown in FIG. 11B9, when the [CHANGE] (change function) key 11d is operated (step S23 (Yes)), the function operated immediately before by the user is the change function data "CHANGE". , it is determined that the change has just been calculated (that is, the input of the [CHANGE] (change function) key 11d this time is a repeated input) (step S24 (Yes)).

Then, the current line number "06" is decremented by (-2) to be updated to "04" (step S24a), and the numerical data ( The calculation result data (second change data) "200" obtained by subtracting the payment amount data "360" stored in the payment amount memory 22f from the second numerical data "560" is as shown in FIG. 11 (B9). is displayed again as change data (step S25).

Then, in the same manner as described above, as shown in FIG. 3B, the deposit amount data (second numerical data) "560" and the change function are stored in the memory area of the current row number "04" of the calculation data memory 22c. The data "CHANGE" is overwritten and saved, the line number is incremented by (1) to be updated to "05", and the change data (second change data) "200", which is the calculation result data, is overwritten and saved. (step S26).

Here, as shown in FIG. 11 (B10), when the user inputs numerical data "5" as the operand of the next calculation (step S9 (Yes)), the change is calculated in the same manner as described above. 8 (step S10 (Yes)), and the process proceeds to the line number provisional display process in FIG. 8 (step SA).

Then, it is determined that the current line number display mode is "3" (step A2 (No)), and the line number obtained by adding (+1) the current line number "05" in the line number data/line number provisional display data memory 22d. (Temporary display) Data "06" is stored (step A5).

Then, although the current line number "05" is incremented by (1) and updated to "06", here, as shown in FIG. (Temporary display) Displayed in association with data "06" (step S11).

That is, here again, regarding the input numerical data "5", the calculator 10A assumes that it is the numerical data input as the operand of the next calculation, and the last change data "200" is saved. Data "06" of a new line number (temporary display) obtained by adding (+1) the line number "05" is displayed.

Then, as shown in FIG. 11 (B11), when the [x] (multiplication) key is operated (step S12 (Yes)), the calculation data memory 22c (FIG. 3) corresponding to the current row number "06" Calculation data consisting of the displayed numerical data "5" and the operation data "x" input by the [x] (multiplication) key is stored in the memory area (see step S13).

As a result, immediately after inputting deposit amount data and temporarily calculating and displaying change data for payment amount data, which is total (calculation result) data corresponding to a series of calculation data, different deposit amount data can be displayed. Even if the numerical data (deposit amount data) for re-inputting and re-calculating the change data or numerical data for the next calculation are input, the line number provisional display process ( According to mode 3), the input numerical data is assumed to be the numerical data input as the operand of the next calculation, and a new row number (temporary Display) Displayed in association with data "06". Therefore, the calculator 10A can clearly indicate that the storage destination of the input numerical data is the storage destination of the numerical data input for the next calculation at the present time.

Therefore, even when the change is calculated by inputting the deposit amount and then recalculating the change by repeatedly inputting a new deposit amount, it is possible to display a line number that is easy for the user to understand according to the recalculation operation. be possible.

In addition, in the calculation data display process in the line number display mode "3", as shown in FIG. ” is assumed to be numerical data input as an operand of the next calculation, and is displayed in association with the current row number “05” (+1) to the row number (temporary display) data “06” ( S9, S10, SA, S11). Then, as shown in FIG. 11(B9), according to the operation of the [CHANGE] (change function) key 11d, it is judged that the calculation of the change data is repeated, and the input numerical data (deposit amount data) " 560” and the change function data “CHANGE” are overwritten and saved in the memory area of line number “04”, which is the storage destination of the previous deposit amount data, and the current change data “200” is stored in line number “05”. was overwritten and saved in the memory area of , and displayed in association with the line number "05" (S23, S24, S24a, S25, S26).

On the other hand, when it is determined that the change data is to be calculated repeatedly according to the operation of the [CHANGE] (change function) key 11d, as shown in FIG. Amount data) "560" is displayed in association with the row number "04", which is the storage destination (overwrite destination), and then the current change data "200" is displayed as shown in FIG. By displaying in association with the line number "05", the overwritten storage destination of the re-inputted numerical data (deposit amount data) "560" to the re-calculated change data "200" is displayed in a more comprehensible manner. may be configured.

Therefore, according to the calculator 10 (10A, 10B) configured as described above, a combination of numerical data and operation data "+", "-", "x", and "÷", numerical data and execution function data "= , numerical data (deposit amount) and change function data "CHANGE" are sequentially input and displayed, and calculation is executed in response to the input of the execution function data "=". When the calculated total (calculation result) data is displayed, and when the change data calculated according to the input of the change function data "CHANGE" is displayed, the displayed calculation data is sequentially displayed, It has a calculation data saving mode for saving in correspondence with the row number of the calculation data memory 22c, and each calculation data is displayed in association with the row number as the saving destination.

Immediately after the change data is once calculated, when the numerical data (deposit amount) and the change function data "CHANGE" are repeatedly input and the change data is recalculated, the numerical data (deposit amount) and the change accompanying the recalculation are input. The set of function data "CHANGE" and its change data are overwritten and saved on each data saved according to the calculation of the immediately preceding change data.

If the numerical data is re-entered immediately after the change data is once calculated, the re-entered numerical data will not be re-calculated in line number display mode "1". Since it is unclear whether it is the deposit amount data or the numerical data for the next calculation, it is displayed in association with the line number (temporary display) data "---" (or blank). In the line number display mode "2", it is assumed that the re-entered numerical data is deposit amount data for recalculating the change data, and the current line number where the last change data is stored is displayed. is displayed in association with the row number (temporary display) data corresponding to the storage destination of the previous deposit amount data minus 1. In the line number display mode "3", it is assumed that the re-entered numerical data is the numerical data inputted as the operand of the next calculation, and the current change data storage destination of the immediately preceding change data is stored. The line number (temporary display) data corresponding to the storage destination of the next calculation data whose line number is incremented by (+1) is displayed in association with it.

After that, when the [CHANGE] (change function) key 11d is input, the re-input numerical data is overwritten and saved as deposit amount data (second numerical data), and [+] [-] [X] is displayed. ][÷] is input, the re-input numerical data is saved as numerical data for the next calculation in association with the next line number. In the line number display mode "1", when the user operates [CHANGE] (change function), the second change data is calculated by subtracting the payment amount data from the second numerical data.

Thus, for example, the user can select and set one of the line number display modes "1 to 4" in advance depending on whether or not there are frequent opportunities to recalculate the change data. , After calculating the change by entering the deposit amount, even if you repeatedly enter a new deposit amount and recalculate the change, it is possible to display a line number that is easy for the user to understand according to the recalculation operation. become.

When one of the line number display modes "1 to 3" is set, the input numerical data (deposit amount data) and the recalculated change data are stored in the calculation data memory according to the recalculation of the change data. Since the numerical data (deposit amount data) previously input in 22c and the previously calculated change data are overwritten and saved in the storage destination, even if the change data is repeatedly calculated, the memory of the calculation data memory 22c is saved. Saves space and can be used.
