Here, as shown in FIG. 11 (A3), the calculation operation data of the calculation data memory 22d is cleared based on the operation of the [CA] key 11h, and therefore, as shown in FIG. 11 (B1). , The registration data print start mark "... 0 ..." indicating that the printing is [CA] (clear all) printing in the reprint mode is printed on the recording paper P by the printing unit 13. Only (step P1), no calculation data is printed even if the current line number data for the calculation data memory 22d is updated after “01” (steps P2 to P8 (No) → return).

Here, assuming that the calculator 10 with a printer is used in a Chinese shop, a Japanese person purchases four products of 300 yuan, and the shipping fee of the purchased products to Japan becomes 100 yuan. Suppose you want to calculate how much the total amount including the shipping fee will be in yen conversion.

As shown in FIG. 11 (A7), when the numerical data "300" which is the price of the product is input in response to the user operation of the numerical key (step S8 (Yes)), the data of the line number is displayed. It is (+1), updated to "01", and displayed on the display unit 12. Further, the input numerical data "300" is displayed on the display unit 12. Then, the state flag of the state flag memory 22f is set to the [numerical value input state] (step S9).

Then, when the calculation data [x] is input in response to the operation of the calculation key [x] (multiplication) (step S9a (Yes)), the current line number data "01" stored in the line number memory 22e In response to the above, the input numerical data "300" and the calculation data [x] are stored and registered in the area of the line number "01" of the calculation data memory 22d (see FIG. 3) (step). S9b).

Subsequently, as shown in FIG. 11 (A8), when the numerical data "4" which is the number of purchased products is input (step S8 (Yes)), the line number data is (+1) in the same manner as described above. Is updated to "02" and displayed on the display unit 12 (step S9).

Then, when the calculation data [+ =] is input in response to the operation of the calculation key [+ =] (addition total) (step S9a (Yes)), the current line number stored in the line number memory 22e The input numerical data "4" and the calculation data [+ =] are stored and registered in the area of the line number "02" of the calculation data memory 22d (see FIG. 3) according to the data "02". (Step S9b).

Then, the calculation according to the calculation operation data "300 [x] 4 [+ =]" registered in the calculation data memory 22d is executed, and the calculation result data "1200" as the total amount of the purchased products is displayed. It is displayed in unit 12 (step S9c).

Subsequently, as shown in FIG. 11 (A9), when the numerical data "100" which is the shipping fee of the purchased product is input (step S8 (Yes)), the line number data is (+1) in the same manner as described above. Is updated to "03" and displayed on the display unit 12 (step S9).

Then, when the calculation data [+ =] is input in response to the operation of the calculation key [+ =] (addition total) (step S9a (Yes)), the current line number memory 22e is stored in the same manner as described above.

Then, the calculation according to the calculation operation data "100 [+ =]" registered in the calculation data memory 22d is executed, and the calculation result data "1300" as the total amount including the shipping fee of the purchased product is displayed on the display unit. It is displayed in 12 (step S9c).

Here, after the total amount "1300 yuan" including the shipping fee of the purchased product is specified as the conversion target by operating the [*] (total) key 11n, the total amount "1300 yuan" is changed from "yuan" to "yuan". To convert to "yen", first, as shown in FIG. 11 (A10), when the [C2] (currency 2) key 11l for which the conversion rate of "yuan" is set is operated (step S10h (Yes)). , The data of the line number is (+1), updated to "04", and displayed. Then, the displayed numerical data "1300" was divided by the conversion rate [C2: 6.585 yuan / $] of the "yuan" registered in the conversion rate memory 22g, and converted into the basic currency "$". The total amount "197.4183 ..." is calculated (step S10i).

Then, according to the current line number data "04" stored in the line number memory 22e, the numerical value displayed in the area of the line number "04" of the calculation data memory 22d (see FIG. 3). The calculation operation data "[÷] [C2]" that divides the data "1300" by the conversion rate [C2] is stored and registered (step S10j).

In the state during the correction operation of the calculation operation data corresponding to the above, even if the [REPRINT] (registered data print) key 11g is operated (step S51a (Yes) / S53a (Yes)), nothing Printing is not performed and unnecessary printing is prevented.

After that, as shown in FIGS. 12 (A11) to 12 (A13), when the registration data confirmation key ([▽] key 11d) is repeatedly operated (step S46 (Yes)), the current line number is used each time. It is confirmed whether or not there is calculation operation data registered in the calculation data memory 22d in association with the line number next to (step S47). Then, when there is calculation operation data associated with the next line number (step S47 (Yes)), the calculation operation data is called and displayed on the display unit 12 together with the next line number. (Step S48).

That is, as shown in FIG. 12 (A11), when the registration data confirmation key ([▽] key 11d) is operated (second time in the confirmation mode), it is registered corresponding to the line number "01". Tax-included amount data (tax calculation 1 result data) calculated based on tax-included calculation operation data (numerical data (tax-excluded amount data) "300" and tax-included data (tax calculation 1 data) [TAX +]) after correction ) "324" and the symbol "TAX +" corresponding to the tax-included data [TAX +] called corresponding to the line number "02" are displayed.

Further, as shown in FIG. 12 (A12), when the registration data confirmation key ([▽] key 11d) is operated (third time), the tax-included data registered corresponding to the line number “02” is included. (Tax calculation 1 data) According to the tax amount data "24" as a result of the tax-included calculation (tax calculation 1) based on [TAX +] and the tax-included data [TAX +] called corresponding to the line number "03". The symbol "TAX +" is displayed.

Further, as shown in FIG. 12A13, when the registration data confirmation key ([▽] key 11d) is operated (fourth time), the tax-included data registered corresponding to the line number “03” is included. The tax-included amount data "324" as a result of the tax-included calculation (tax calculation) based on [TAX +] and the tax-excluded data (tax calculation 2 data) [TAX-] called corresponding to the line number "04" The corresponding symbol "TAX-" is displayed.

As a result, even after modifying a part of the series of calculation data calculated by tax by the tax-included calculation (or tax-excluded calculation), the registration data confirmation key ([▽] key 11d) can be repeatedly operated to obtain the relevant data. You can easily check the revised tax-included amount data, tax amount data, and tax-excluded amount data.

When the registration data confirmation key ([Δ] key 11e) is operated to set the confirmation (search) mode in step S44, the registration is registered in association with each line number of the calculation data memory 22d. Of the series of calculation operation data, the calculation operation data associated with the last line number is called and displayed (step S45).

Further, in the confirmation (search) mode, when the registration data confirmation key ([Δ] key 11e) is operated (step S46 (Yes)), it is associated with the line number before the current line number. The calculation operation data registered in the calculation data memory 22d is called, and the result data and symbols of the tax calculation based on the calculation operation data are displayed (steps S47 and S48).

Then, as shown in FIG. 12 (A14), the tax-included amount data (tax calculation 1 result data) "324" corresponding to the calculation operation data (tax-included data (tax calculation 1 data) [TAX +]) of the line number "03". Is displayed and the [REPRINT] (registered data print) key 11g is operated (step S56 (Yes)), the registered data printing process shown in FIG. 10 is executed (step SP).

That is, when the registration data printing process is started, as shown in FIG. 12B2, the registration data printing start mark "..." indicating that the printing is [CA] (clear all) printing in the reprint mode. 0 ... ”is printed on the recording paper P by the printing unit 13 (step P1).

Then, the current line number data of the line number memory 22e is set to "01" (step P2), and the calculation operation associated with the current line number "01" and registered in the calculation data memory 22d. It is determined whether or not the data is calculation operation data including numerical data and calculation data or tax-included (or tax-excluded) data (step P3).

Here, the calculation operation data associated with the current line number “01” and registered in the calculation data memory 22d (see FIG. 4B) are numerical data “300” and tax-included data (tax calculation 1). Data) It is determined that the calculation operation data includes [TAX +] (step P3 (Yes)).

Then, following the registration data print start mark "... 0 ..." printed on the recording paper P, the tax calculation print data corresponding to the numerical data "300" and the tax-included data [TAX +] is used. , The numerical data (tax-excluded data) "300" and tax-excluded mark "-T", tax rate data "8" and tax rate mark "% T", tax amount data "24" and tax amount mark "T", including tax. The amount data (tax calculation 1 result data) “324” and the tax-included amount mark “+ T” are printed on the recording paper P by the printing unit 13 (step P4).

After that, it is determined whether or not the calculation data memory 22d (see FIG. 4B) has the calculation operation data associated with the next line number (step P8). Here, it is determined that there is calculation operation data (tax-included data [TAX +]) associated with the next line number “02” (step P8 (Yes)), and the current line number “01” of the line number memory 22e is determined. Is (+1) and updated to “02” (step P9).

Then, the calculation operation data associated with the current line number “02” and registered in the calculation data memory 22d (see FIG. 4B) is tax-included data (tax calculation 1 data) [TAX +]. It is determined that the data is not calculation operation data including numerical data and tax-included (or tax-excluded) data (step P3 (No)). In addition, there is tax-included data (tax calculation 1 data) [TAX +] in both the calculation operation data associated with the immediately preceding line number "01" and the calculation operation data associated with the current line number "02". Then, it is determined that the tax calculation data is continuous (step P5 (Yes)). In this case, printing is not performed on the recording paper P (printing is suppressed) (step P6).

After that, even when the current line number "02" is updated from "03" to "04" in the same manner as described above (steps P8 (Yes), P9), the calculation associated with each line number is similarly performed. Since the operation data is determined to be continuous tax calculation data (steps P3 (No), P5 (Yes)), printing is not performed on the recording paper P (printing is suppressed) (step P6).

As a result, even after a part of the series of calculation data calculated by tax by the tax-included calculation (or tax-excluded calculation) is corrected, the correction is performed by operating the [REPRINT] (registered data print) key 11g. The tax-excluded amount data (-T), the tax rate data (% T), the tax amount data (T), and the tax-included amount data (+ T) according to the result data of the tax-included calculation can be easily printed on the recording paper P.

In this case, since the registration data print start mark "... 0 ..." is printed at the head of the recording paper P, the user can use the [CA] key 11h in the print mode (ON). Clearly distinguish from normal printing (normal printing start mark "... 0 ...") according to the operation of, and confirm that the registered data is printed after correction according to the operation of the [REPRINT] key 11g. can do.

Note that the calculation operation data associated with the current line number and registered in the calculation data memory 22d is not the calculation data including the numerical data and the calculation data or the tax-included (or tax-excluded) data (step P3 (No.). )), If it is determined that the tax calculation data is not continuous (step P5 (No)), the calculation operation data registered in association with the current line number is printed (step P7).

In the second embodiment described with reference to FIG. 12, for example, after inputting the numerical data “200” which is the product price (tax excluded amount), the [TAX +] (tax included calculation: tax calculation 1) key 11b is repeatedly operated. Then, display the tax-included amount data "216" → tax amount data "16" → tax-included amount data "216", and then operate the [TAX-] (tax-excluded calculation: tax calculation 2) key 11c to display the tax-excluded amount data. The process of displaying "200" has been described as a process according to steps S10 to S23 shown in FIG. 6 and steps S41 to S43 shown in FIG. 7.

On the other hand, for example, after inputting the numerical data which is the product price (tax included amount), the [TAX-] (tax excluded calculation: tax calculation 2) key 11c is repeatedly operated to tax-excluded amount data → tax amount data → tax-excluded amount data. After that, for the process of operating the [TAX +] (tax included calculation: tax calculation 1) key 11b to display the tax included amount data, the above-mentioned "tax included" [TAX +] and "tax excluded" [TAX-] The process is the same as described above except that the handling of the above is reversed, and the process is performed according to steps S27 to S40 shown in FIG. 7 and steps S24 to S26 shown in FIG.

Therefore, according to the printer-equipped calculator 10 of the second embodiment of the above configuration, the input numerical data and the operation of the tax calculation key ([TAX +] (tax-included calculation) key or [TAX-] (tax-excluded calculation) key) The tax-included data (or tax-excluded data) corresponding to is registered in the calculation data memory 22d as the calculation operation data associated with the row number data to be updated sequentially, and the registration data confirmation key ([▽] key 11d or [△]] When the key 11e) is operated, the registered calculation operation data is called in order from the calculation operation data associated with the first (or end) line number data for each key operation, and the called calculation operation is performed. The tax-included amount data (or tax-excluded amount data) and the tax amount data according to the data are displayed in sequence. Then, when the [CORRECT] (correction) key 11f is operated, the correction mode is set, and the numerical data of the displayed tax-included amount data (or tax-excluded amount data) can be corrected. After that, when the [REPRINT] (registered data print) key 11g is operated, the tax-excluded amount data (-T), the tax rate data (% T), the tax amount data (T), and the tax-included amount according to the corrected numerical data are operated. The data (+ T) is printed on the recording paper P. In the state of the correction operation of the calculation operation data, no printing is performed even when the [REPRINT] (registered data printing) key 11g is operated, and unnecessary printing is prevented.

This makes it possible to easily check and correct the contents of the tax calculation, and to prevent unnecessary printing and save money.
