Abstract
The invention provides an arithmetic device which can print operation data registered according to an operation according to a user operation, eliminate redundant printing and properly perform required printing. In the print mode (open), the operation data and the operation result data corresponding to the user operation can be sequentially printed on the recording paper P, and even in the print mode (closed), the operation data and the operation result data corresponding to the series of operation data registered in the operation data memory can be collectively printed on the recording paper P by operating the [ reprint ] (registration data printing) key. In addition, regardless of the state of the print mode, when the process of the arithmetic processing is in a state in which the conversion rate is set or in a state in which the conversion operation is performed, no printing is performed even if the [ reprint ] key is operated, and therefore, redundant printing can be prevented.
Description
Technical Field
The present invention relates to an arithmetic device such as an electronic desk calculator having an arithmetic function, an arithmetic printing method, and an arithmetic program storage medium.

The operation of the desktop electronic calculator 10 will be described below.
Fig. 5 to 9 are flowcharts showing (one to five) the arithmetic data printing process of the desktop calculator 10.
Fig. 10 is a flowchart showing a registered data printing process in the arithmetic data printing process (fifthly) of the desktop calculator 10.
(first embodiment)
In the first embodiment, an operation corresponding to a money conversion function in a state where the setting data of the print mode OFF is stored in the print mode memory 22b will be described.
Fig. 11 is a diagram showing a display/printing operation corresponding to the user operation in the first embodiment of the arithmetic data printing process.
In the desktop electronic calculator 10, when the power is turned on (here, the power key 11E is switched to the position of [ conversion ] (currency conversion)) according to the user operation, the setting data of the print mode (on) is stored in the print mode memory 22b, the setting data of the registration mode is stored in the arithmetic mode memory 22c, and the data of the line number "0" is stored in the line number memory 22E as the processing with the initial setting of the power on by the CPU21 (step S1).
In the state of the print mode (on), as shown in (a1) in fig. 11, if the [ PRT ] (print mode) key 11a is operated (yes in step S2), the setting data of the print mode (on) is switched to the setting data of the print mode (off) (step S3).
Then, when the [ CA ] key 11h is operated (yes in step S4), the data of the line number is changed and set to "0" (step S5).
Here, for example, when the conversion rate of "yen" corresponding to the basic currency "$" is 111.2 yen/$, and the conversion rate of "yen" is 6.585 yen/$, as shown in (a2) in fig. 11, since the yen exchange rate corresponding to "yen" is known, first, when numerical value data "111.2" is input (yes in step S8), the data of the line number is (+1) updated to "01", and is displayed on the display unit 12. The input numerical data "111.2" is displayed on the display unit 12. Then, the status flag of the status flag memory 22f is set to "numerical value input status" (step S9).
Then, when operator data [ ÷ ] (step S9a (yes)) is input in accordance with the operation of the operator key [ ÷ ] (division calculation), the input numerical value data "111.2" and the operator data [ ÷ ] are stored and registered in the area of the line number "01" of the arithmetic data memory 22d in accordance with the current line number data "01" stored in the line number memory 22e (step S9 b).
Next, when the numerical value data "6.585" is input (yes in step S8), the data of the line number is updated to "02" by (+1) in the same manner as described above, and is displayed on the display unit 12 (step S9).
Then, when operator data [ + ═ is inputted from the operation of the operator key [ + ═ to (addition calculation total) (yes in step S9 a), the inputted numerical value data "6.585" and the operator data [ + ═ are stored and registered in the area of the row number "02" of the operation data memory 22d from the current row number data "02" stored in the row number memory 22e (step S9 b). If the operator key [ + ═ is not operated (addition calculation total), the routine proceeds to (step S9a (no)) shown in fig. 6.
After step S9b, an operation corresponding to the arithmetic operation data "111.2 [ ÷ ]6.585[ + ═ ]" registered in the arithmetic data memory 22d is performed, and the operation result data "16.886 … …" (yen/yen) as the yen exchange rate corresponding to the "yen" is displayed on the display section 12 (step S9 c).
Here, since the printing mode (off) is in the state, the printing of the arithmetic operation data "111.2 [ ÷ 6.585[ + ═ and" and the arithmetic result data "16.886 … …" is not performed (step S9d (no)).
When the CPU21 determines that the print mode (on) is set (yes in step S9 d), the printing unit 13 sequentially prints the arithmetic operation data "16.886 … …" and the arithmetic result data "16.886 … …" on the recording paper P every time the arithmetic operation data "111.2 [ ÷ and" 6.585[ + ═ are registered in the arithmetic data memory 22d (step S9 e).
Next, in order to set the conversion ratios of "japanese" and "yuan", as shown in (a3) of fig. 11, when the [ CA ] key 11h is operated again (yes at step S4), the data of the line number is changed and set to "0" (step S5).
After the [ CA ] key 11h is operated (yes in step S4), as shown in fig. 8, if the [% (set) conversion rate (set) key 11i is pressed for a long time of 3 seconds or longer (yes in step S10 a), the process proceeds to step S10 b.
Next, as shown in (a4) in fig. 11, numerical value data "111.2" is input and displayed as the conversion rate of the "yen" (yes at step S10b → S10d), and as shown in (a5) in fig. 11, when the [ C1] (currency 1) key 11k is operated (yes at step S10 e), the conversion rate of the "yen" is registered in the conversion rate memory 22g [ C1: 111.2 yen/$ ] (step S10 g).
As shown in (A3) and (a4) of fig. 11, even when the [ reprint ] (registered data print) key 11g is operated (yes at step S10C) in the state of the conversion ratio setting from the long press operation of the [% (set) ] (set conversion ratio) key 11i (yes at step S10 a) to the time before the [ C1] (money 1) key 11k is operated (step S10d), no printing is performed, and thus, unnecessary printing is prevented.
Thereafter, similarly to the setting of the conversion rate of the "yen", in order to set the conversion rate of the "yen", as shown in (a6) in fig. 11, when the [% (setting) ] (conversion rate setting) key 11i is pressed again (yes in step S10 a), numeric value data "6.585" is input and displayed (yes in step S10b → S10d), and when the [ C2] (currency 2) key 11l is operated (yes in step S10 e), the conversion rate of the "yen" is registered in the conversion rate memory 22g [ C2: 6.585 bits/$ (step S10 g).
Here, as described above, in the setting of the conversion ratio from the state of long press of the [% (set) ] (set conversion ratio) key 11i (yes in step S10 a) to the state of not operating the [ C2] (money 2) key 11l (step S10d), even if the [ reprint ] (registered data print) key 11g is operated (yes in step S10 f), no printing is performed, and thus redundant printing is prevented.
As shown in (a6) of fig. 11, when the [ reprint ] (registered data print) key 11g is operated from (r) to (v) after the conversion rate of "japanese yen" or "yuan" is registered in the conversion rate memory 22g (yes in step S57), the process proceeds to (step S58) when the registered data print processing SP is executed (fig. 9) but the [ reprint ] (registered data print) key 11g is not operated.
In the registered data printing process SP, as shown in fig. 11a 3, since the arithmetic operation data in the arithmetic data memory 22d is erased based on the operation of the [ CA ] key 11h, when the [ reprint ] (registered data printing) key 11g is operated, as shown in fig. 11B 1, since the registered data printing start mark "· · 0 · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · when the [ reprint ] (all erased) printing in the reprint mode is merely printed on the recording paper P by the printing section 13 (step P1), even if the current line number data with respect to the arithmetic data memory 22d is updated to" 01 "or more", no arithmetic operation data, such arithmetic operation data and arithmetic result data are not printed (steps P2 to P8 (no) → return).
Here, it is assumed that japanese purchases 4 300-dollar products in a store capable of using chinese dollars, the freight rate of the purchased products for japan is 100 dollars, and the total amount including the freight rate is calculated by converting the total amount into japanese dollars.
As shown in fig. 11a 7, when numerical value data "300" as the price of the product is input in response to the user operation of the numerical value key after the operation of the [ CA ] key 11h (yes in step S4 and no in step S6) (yes in step S8), the data of the line number is (+1) updated to "01", and displayed on the display unit 12. The input numerical value data "300" is displayed on the display unit 12. Then, the status flag of the status flag memory 22f is set to "numerical value input status" (step S9).
Then, when operator data [ x ] is input in accordance with an operation of an operator key [ x ] (multiplication) (yes in step S9 a), the input numerical value data "300" and the operator data [ x ] are stored and registered in an area of a row number "01" of the operation data memory 22d (see fig. 3) in accordance with the current row number data "01" stored in the row number memory 22e (no in step S9b, step S9c, step S9 d).
Next, as shown in (A8) of fig. 11, when numerical data "4" as the number of purchased products is input (yes in step S8), the data of the line number is updated to "02" by (+1) as described above, and displayed on the display unit 12 (step S9).
Then, when operator data [ + ═ is input by an operation of an operator key [ + ═ in ] (addition calculation total) (yes in step S9 a), the input numerical value data "4" and the operator data [ + ═ are stored and registered in an area of a row number "02" in the operation data memory 22d (see fig. 3) from the current row number data "02" stored in the row number memory 22e (step S9 b).
Then, an operation corresponding to the operation data "300 [ × ]4[ + ═ ]" registered in the operation data memory 22d is executed, and the operation result data "1200" as the total amount of the purchased products is displayed on the display unit 12 (step S9 c).
Next, as shown in (a9) of fig. 11, when numerical data "100" as the freight rate of the purchased product is input (yes in step S8), the data of the line number is updated to "03" by (+1) in the same manner as described above, and is displayed on the display unit 12 (step S9).
Then, when operator data [ + ═ is inputted by an operation of an operator key [ + ═ to (addition calculation total) (yes in step S9 a), the inputted numerical value data "100" and the operator data [ + ]arestored and registered in an area of a row number "03" in the operation data memory 22d (see fig. 3) from the current row number data "03" stored in the row number memory 22e in the same manner as described above (step S9 b).
Then, the calculation corresponding to the calculation operation data "100 [ + ═ ]" registered in the calculation data memory 22d is executed, and the calculation result data "1300" which is the total amount including the freight rate of the purchased product is displayed on the display unit 12 (step S9 c).
Here, when the total amount "1300 yuan" including the freight rate of the purchased product is designated as a conversion target by the operation of the [ ("total") key 11n, the routine proceeds to step S9f (yes) shown in fig. 8. In step S9f, if the [ (total) key 11n is not operated, the process proceeds to step S9 d. In order to convert the total "1300 yuan" from "yuan" to "yen", first, as shown in fig. 11 (a10), when the [ C2] (currency 2) key 11l in 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 value data "1300" is divided by the conversion rate of "element" registered in the conversion rate memory 22g [ C2: 6.585 yen/$ ], and calculates a total amount "197.4183 … …" converted into a basic currency "$" (step S10 i).
Then, the arithmetic operation data "[ ÷ ] [ C2 ]" obtained by dividing the displayed numerical value data "1300" by the conversion rate [ C2] is stored and registered in the area of the line number "04" of the arithmetic data memory 22d (see fig. 3) based on the current line number data "04" stored in the line number memory 22e (step S10 j).
Here, for example, in a case where it is determined that the state of the print mode (open) is present (yes in step S10 k), as shown in (B2) in fig. 11, immediately following the operation formula portion "300 [ × ]4[ + ═ 100[ + ]" of the operation data associated with the line numbers "01" to "03" printed on the recording paper P and the operation result data "1300" thereof, as shown in (B2) PR1 in fig. 11, the numerical value data "1300" displayed as described above is divided by the conversion rate of the "element" [ C2: the operation formula part of the operation data of 6.585 bits/$ and the operation result data "197.4183 … … $" are printed as operation data (S10 l).
In the first embodiment, since the print mode is set (off), the printing in step S10l is not performed.
As shown in (a10) and (a11) of fig. 11, even when the [ reprint ] (registered data print) key 11g is operated (yes at step S10 n), no printing is performed in the conversion operation from the operation of the [ C2] (money 2) key 11l (yes at step S10 h) to the operation of the [ C1] (money 1) key 11k (step S10j), thereby preventing redundant printing.
Thereafter, as shown in (a11) in fig. 11, when the [ C1] (currency 1) key 11k in which the conversion rate of "yen" is set is operated (yes in step S10 m), the numerical value data "197.4183 … …" $ "converted into the basic currency" $ "is multiplied by the conversion rate of" yen "registered in the conversion rate memory 22g [ C1: 111.2 yen/$ ], and calculates the total amount "21953" yen converted to "yen" (step S10 o).
Then, the data of the line number is updated to "05" and displayed (+1), and in the area of the line number "05" of the arithmetic data memory 22d (see fig. 3), arithmetic operation data "[ × ] [ C1 ]" obtained by dividing the numerical value data "197.4183 … …" $ converted from the "element" into "dollars" by the conversion rate [ C1] of the "yen" is stored and registered (step S10 p).
Then, the display unit 12 displays operation result data "21953" obtained by multiplying the numerical value data "197.4183 … …" $ converted from "yuan" by the conversion rate [ C1] of "yen" (step S10 q).
Here, for example, in a case where it is determined that the state of the print mode (open) is present (yes in step S10 r), as shown in (B2) PR1 in fig. 11 described above, the operation formula portion "300 [ × ]4[ + ]100[ + ═ ]" and the operation result data "1300" thereof immediately following the operation data associated with the line numbers "01" to "04" printed on the recording paper P, and the conversion rate [ C2: the operation formula portion of the operation data of 6.585 bits/$ ] and the operation result data "197.4183 … … $" thereof are, as shown in (B2) PR2 in fig. 11, obtained by multiplying the numerical value data "197.4183 … …" converted into the base currency "$" by the conversion rate of the "yen" [ C1: the operation formula part of the operation data of 111.2 yen/$ and the operation result data "21953" are printed (step 10 s).
In the first embodiment, since the print mode is set (off), the printing of the arithmetic data such as the arithmetic formula part of the arithmetic operation data or the arithmetic result data in step S10S is not performed.
Then, as shown in fig. 11 (a11), after conversion of the money from the total amount "1300" of the "yen" to the total amount "21953" of the "yen" in accordance with the operation of the [ C2] (money 2) key 11l to the [ C1] (money 1) key 11k is completed, the [ reprint ] (registration data printing) key 11g is operated (step S57 (yes) → SP) after the lapse of (r) to (r), and then the registration data printing process shown in fig. 10 is executed.
When the registered data printing process is started, as shown in (B2) of fig. 11, the printing unit 13 prints a registered data printing start mark "· · 0 · · · · · · · · · · · · · ·", which indicates a case of [ CA ] (all clear) printing in the reprint mode (step P1).
Then, the current line number data of the line number memory 22e is set to "01" (step P2), and it is judged whether or not the arithmetic operation data associated with the current line number "01" and registered in the arithmetic data memory 22d is arithmetic data of an arithmetic formula section including numerical value data, operator data, or arithmetic operation data including tax (or non-tax) data (step P3).
Here, it is determined that the arithmetic operation data which is associated with the current line number "01" and is registered in the arithmetic data memory 22d (see fig. 3) is arithmetic operation data including numerical value data "300" and operator data [ × ] (step P3 (yes)).
Then, immediately after the registration data printing start mark "· · 0 · · · · · · · · · · · · · · · · · · · · · printed on the recording paper P, the arithmetic data corresponding to the numerical value data" 300 "and the operator data [ × ] is printed on the recording paper P by the printing portion 13 (step P4).
Thereafter, it is determined whether or not the arithmetic operation data associated with the next line number exists in the arithmetic data memory 22d (see fig. 3) (step P8). Here, it is determined that there is arithmetic operation data (4[ + ═ ]) associated with the next line number "02" (yes in step P8), and the current line number "01" of the line number memory 22e is updated to "02" (step P9) by (+ 1).
Then, it is determined that the arithmetic operation data stored in the arithmetic data memory 22d (see fig. 3) in association with the current line number "02" is arithmetic operation data including numerical value data "4" and operator data [ + ═ as ] as in the above-described case (yes at step P3), and arithmetic data corresponding to the numerical value data "4" and operator data [ + ═ and its arithmetic result data "1200" are printed on the recording paper P by the printing unit 13 (step P4).
Thereafter, as shown in fig. 11B 2, the operation data corresponding to the operation data registered in each of the line numbers "03" to "05" of the operation data memory 22d (see fig. 3) and the operation result data thereof are printed in sequence as (100[ + ]) (1300 [) ] … … (21953[ C ]) (steps P3, P4, P8, and P9).
Thus, even in the state of the print mode (off), if the money conversion is completed, by operating the [ reprint ] (registered data print) key 11g, the arithmetic formula portion corresponding to the series of arithmetic operation data associated with the purchase of the product and the series of arithmetic operation data associated with the money conversion, and the arithmetic result data thereof can be easily printed on the recording paper P.
Therefore, according to the desktop calculator 10 of the first embodiment having the above-described configuration, the operation formula portion of the operation data and the operation result data corresponding to the user operation can be sequentially printed on the recording paper P in the print mode (open state), and even in the print mode (closed state), if the money conversion is completed, the operation formula portion of the series of operation data registered in the operation data memory 22d and the operation result data thereof can be collectively printed on the recording paper P by operating the [ reprint ] (registered data printing) key 11 g. Further, regardless of the state of the print mode on/off, when the process of the money conversion process is in a state in which the conversion rate is set or in a state in which the conversion operation is performed, no printing is performed even if the [ reprint ] (registered data printing) key 11g is operated, and therefore, it is possible to prevent redundant printing.
Thus, since the printing can be performed in accordance with the user operation after the completion of the money conversion with respect to the calculation data registered in accordance with the calculation operation, it is possible to eliminate redundant printing that is repeated by the printing instruction before the completion of the money conversion, and to appropriately perform necessary printing.
(second embodiment)
In the second embodiment, an operation corresponding to a tax calculation function in a state where the setting data of the print mode on is stored in the print mode memory 22b will be described.
Fig. 12 is a diagram showing a display/print operation corresponding to a user operation in the second embodiment of the arithmetic data print processing.
In the desktop electronic calculator 10, in a state of the print mode (on) in which the setting data of the print mode (on) is stored in the print mode memory 22b (step S1), for example, as shown in (a1) of fig. 12, if the [ CA ] key 11h is operated (yes in step S4), the data of the line number memory 22e is set to "0" (step S5). Numerical value data "0" and a symbol "PRT" indicating a state in the print mode (on) are displayed in the display portion 12.
Here, when the CPU21 determines that the state is the print mode (open) (yes in step S6), the printing unit 13 prints a normal print start mark "· · 0 · · · · · · · · · · · · · · · when the recording paper P is in the print mode (open) state, which indicates a case of printing corresponding to the operation of the [ CA ] (Clear All) key 11h in the print mode (open) (step S7), as shown in (B1) of fig. 12.
As shown in fig. 12 (a2), when numerical value data "200" as a commodity price (not including a tax amount) is input by a user operation of the numerical value key (yes in step S8), the data of the line number is updated to (+1) and displayed on the display unit 12 as "01", and the input numerical value data "200" is displayed on the display unit 12. The state flag of the state flag memory 22f is set to "numerical value input state" (step S9).
Here, as shown in (a3) of fig. 12, when the [ tax + ] (including tax operation: tax operation 1) key 11b is operated (yes at step S10), it is determined whether or not the state flag of the state flag memory 22f is in the "value input state" (step S11).
If it is determined that the status flag is "numerical value input status" (yes in step S11), the input numerical value data "200" and tax (tax 1) data [ tax + ] corresponding to the [ tax + ] (tax 1) key 11b are registered (stored) in the area of the row number "01" of the calculation data memory 22d (see (a) in fig. 4) based on the current row number data "01" stored in the row number memory 22e (step S12).
Then, tax-containing operation (tax operation 1) (tax rate 8% in the present embodiment) is performed on the numerical data "200" (step S13), and the row number data "01" is updated to "02" by (+1) and displayed on the display unit 12, and at the same time, tax-containing data (tax operation 1 result data) "216" after the tax-containing operation is displayed, and a symbol "tax +" indicating the tax-containing amount is displayed. The status flag of the status flag memory 22f is set to [ tax amount display status including tax operation ] (step S14).
Here, if it is determined that the print mode open setting data is stored in the print mode memory 22B (yes in step S15) and it is determined that the calculation result data of the tax containing calculation (tax calculation 1) is not printed (no in step S16), as shown in (B1) of fig. 12, the normal print start mark "· · 0 · · · · · · · · · · · · · · · · S" is printed on the recording paper P by the printing unit 13, the input numerical data (tax free data) "200" and tax free mark "" T "are printed on the recording paper P, the tax rate data" 8 "and tax free mark"% T "are printed on the next print line, the tax data" 16 "and tax free mark" T "are printed on the next print line, the tax containing data (tax calculation 1 result data)" 216 "and tax containing mark" + T "are printed on the next print line, as the tax operation print data including the tax operation (step S17).
Here, as shown in (a4) of fig. 12, when the [ tax + ] (tax operation: tax operation 1) key 11b is operated again (yes in step S10), it is determined that the status flag of the status flag memory 22f is [ tax amount display status of tax operation ] (yes in step S18).
Then, tax-containing data (tax operation 1 data) [ tax + ] (tax operation: tax operation 1) corresponding to the [ tax + ] (tax operation: tax operation 1) key 11b is stored and registered in the region of the line number "02" of the operation data memory 22d (see (a) in fig. 4) based on the current line number data "02" stored in the line number memory 22e (step S19).
Then, the line number data "02" is updated to "03" and displayed (+1), and the tax amount data "16" after the tax-containing calculation is displayed, and a symbol "tax" indicating the tax amount is displayed. The status flag of the status flag memory 22f is set to [ tax amount display status including tax operation ] (step S20).
Here, as shown in (a5) of fig. 12, when the [ tax + ] key 11b is operated again (yes in step S10), it is determined that the state flag is [ tax amount display state including tax operation ] (yes in step S21).
Then, the tax-containing data (tax operation 1 data) [ tax + ]correspondingto the [ tax + ] key 11b is stored and registered in the area of the line number "03" of the operation data memory 22d (see (a) in fig. 4) based on the current line number data "03" stored in the line number memory 22e (step S22).
The line number data "03" is updated to "04" and displayed (+1), and the tax amount data "216" including the tax operation is displayed again, and a symbol "tax +" indicating the tax amount is displayed. Then, the status flag of the status flag memory 22f is set again to [ tax amount display status including tax operation ] (step S23).
Here, as shown in (a6) of fig. 12, when the [ tax- ] (tax free operation: tax operation 2) key 11c is operated (yes in step S27), if the input of the numerical value is not continued (no in step S28), it is determined that the status flag is [ tax containing (tax containing amount display) status ] (yes in step S41).
Then, the non-tax data (tax operation 2 data) [ tax- ] corresponding to the [ tax- ] key 11c is stored and registered in the area of the line number "04" of the operation data memory 22d (see (a) in fig. 4) based on the current line number data "04" (step S42).
Then, the line number data "04" is updated to "05" and displayed (+1), and the non-tax amount data "200" is displayed, and the symbol "tax-" indicating the non-tax amount is displayed. The status flag of the status flag memory 22f is set to [ tax free display status of tax free operation ] (step S43).
In this way, when the [ tax + ] (inclusive tax operation) key 11b is operated while the numerical data "200" is input, inclusive tax operation is performed, and the data "216" inclusive tax and the symbol "tax +" thereof are displayed, and then the [ tax + ] key 11b is operated, at this time, the data "16" inclusive and the symbol "tax" thereof, and the data "216" inclusive and the symbol "tax +" thereof are alternately displayed every time this operation is performed, and further, when the [ tax- ] key 11c is operated, the data "200" exclusive of tax and the symbol "tax-" thereof can be alternately displayed. Therefore, the content of the tax calculation can be easily confirmed on the display unit 12 at hand.
At this time, after the tax-containing operation (tax operation 1) is executed based on the input of the numerical data "200" and the operation of the [ tax + ] (tax operation-containing) key 11b, and the non-tax amount data (input data) "200. -T", the tax rate data "8. T", the tax amount data "16. T", and the tax amount-containing data (tax operation 2 result data) "216. + T" which are the tax operation print data of the tax-containing operation (tax operation 1) are printed on the recording paper P, the continued operation of the [ tax + ] key 11b or the [ tax- ] key 11b is judged even in the set state where the print mode is on, and the state flag is continued to the [ tax amount-containing (tax amount display/tax amount display) state ] or [ non-tax amount display/amount display) state ] or the non-tax operation (non-tax amount display/amount display) state ], as shown in (a4) to (a6) in fig. 12, tax amount data "16" → tax amount data "216" → tax amount data not "200" are displayed, and printing processing is not performed for each confirmation. Thereby controlling the printing of unnecessary duplicated content so as not to be duplicated.
Next, in order to confirm the contents of a series of operation data corresponding to the tax-containing operation (tax operation 1), as shown in (a7) of fig. 12, when the registered data confirmation key ([) 11d is operated (yes in step S44), the setting data of the operation mode memory 22c is set to a confirmation (verification) mode, and the symbol "REV" of the confirmation mode is displayed on the display unit 12. Further, the operation data (numerical data (data not including tax amount) "200" and data including tax (tax operation 1) [ tax + ]) which are associated with and registered with the line number "01" at the head of the operation data memory 22d are called and displayed on the display unit 12 together with the line number "01" (step S45).
Here, in order to modify the numerical data (not including the tax amount data) "200" corresponding to the line number "01" which is displayed and confirmed on the display unit 12, as shown in (A8) of fig. 12, when the [ modification ] (modification) key 11f is operated (yes in step S49), the setting data of the arithmetic mode memory 22c is set to the modification mode, and the symbol "CRT" of the modification mode is displayed on the display unit 12 (step S50).
Then, as shown in (a9) of fig. 12, correct numerical data "300" is input and displayed (step S51 (yes), S52), and as shown in (a10) of fig. 12, when the [ correction ] (correction) key 11f is operated again (step S53 (yes)), the arithmetic operation data (numerical data (non-tax data)) "200" stored in the arithmetic data memory 22d in association with the current line number "01" is replaced with the input numerical data "300" and registered (step S54) (see (a), (B) of fig. 4). Then, the symbol "CRT" of the correction mode displayed on the display unit 12 is removed (step S55).
As shown in (A8) and (a9) of fig. 12, even when the [ reprint ] (registered data printing) key 11g is operated (yes at step S51 a)/S53 a) in the state in which the correction operation of the arithmetic operation data corresponding to the operation from the first operation (yes at step S49) to the time before the second operation (step S53) of the [ correction ] (correction) key 11f is in progress, no printing is performed, and thus unnecessary printing is prevented.
Thereafter, as shown in (a11) to (a13) of fig. 12, when the registration data confirm key ([ tom ] key 11d) is repeatedly operated (yes in step S46), it is checked whether or not there is operation data associated with the next row number to the current row number and registered in the operation data memory 22d every time the operation is performed (step S47). When there is arithmetic operation data associated with the next line number (yes in step S47), the arithmetic 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 ([ tom ] key 11d) is operated (second time in the confirmation mode), corrected operation data (numerical data (non-tax amount data) "300") registered in association with the row number "01", tax amount data (tax operation 1 result data) "324" after tax amount operation (tax operation 1) is performed based on tax amount data (tax operation 1 data) [ tax + ]) registered by the input operation after the input operation of "200" before correction, and a symbol "tax +" corresponding to the tax amount data [ tax + ] called in association with the row number "02" are displayed. In other words, the tax amount data "324" which is the result of the processing of the tax amount data "tax +" indicated by the symbol (a10) in fig. 12 is displayed with respect to the numerical data "300" indicated by (a10) in fig. 12, and "tax +" in the row number "02" for displaying the tax amount data which is the next processing for the tax amount data "324" is displayed as a mark.
Further, as shown in (a12) in fig. 12, when the registered data confirmation key ([ tom ] key 11d) is operated (third time), tax amount data "24" of the result after the tax-containing operation (tax operation 1) is performed based on tax-containing data (tax operation 1 data) [ tax + ] registered in association with the row number "02" and a symbol "tax +" corresponding to the tax-containing data [ tax + ] called in association with the row number "03" are displayed. In other words, the tax amount data "24" which is the result of the processing of the tax amount-containing data "tax +" indicated by (a11) in fig. 12 is displayed for the numerical value data "324" indicated by (a11) in fig. 12, and "tax +" in the row number "03" for displaying the tax amount-containing data, which is the next processing for the tax amount data "24", is displayed as a symbol.
Further, as shown in (a13) of fig. 12, when the registered data confirmation key ([ tom ] key 11d) is operated (fourth time), tax amount-containing data "324" of a result after the tax-containing operation (tax operation) is performed based on tax-containing data [ tax + ] registered in association with the row number "03" and a symbol "tax-" corresponding to tax-free data (tax operation 2 data) [ tax- ] called in association with the row number "04" are displayed. In other words, the tax amount data "324" which is the result of the processing of the tax amount-containing data "tax +" indicated by (a12) in fig. 12 is displayed for the numerical value data "24" indicated by (a12) in fig. 12, and the "tax-" in the row number "04" for displaying no tax amount data which is the next processing for the tax amount-containing data "324" is displayed as a symbol.
Thus, even after correcting a part of a series of operation data after tax operation by the tax-containing operation (or tax-free operation), the corrected tax-containing data, tax data, and tax-free data can be easily confirmed by repeatedly operating the registered data confirmation key ([. v ] key 11 d).
In the step S44, when the registered data confirmation key ([. DELTA. ] key 11e) is operated and the confirmation (search) mode is set, the arithmetic operation data associated with the last line number is called and displayed among the series of arithmetic operation data registered in association with the line numbers of the arithmetic data memory 22d (step S45).
Further, in the confirmation (search) mode, in the case where the registered data confirmation key ([. DELTA. ] key 11e) is operated (YES in step S46), the arithmetic operation data associated with the line number one before the current line number and registered in the arithmetic data memory 22d is called, and the result data or symbol of the tax operation based on the arithmetic operation data is displayed (steps S47, S48).
Then, as shown in (a14) of fig. 12, when the [ reprint ] (registration data printing) key 11g is operated in a state where tax amount-containing data (tax operation 1 result data) "324" corresponding to the operation data (tax-containing data (tax operation 1 data) [ tax + ]) of the line number "03" is displayed (yes at step S56), the registration data printing process shown in fig. 10 is executed (step SP).
That is, when the registered data printing process is started, as shown in (B2) of fig. 12, the printing unit 13 prints a registered data printing start mark "· · 0 · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · when the recording paper P shows the case of [ CA ] (all clear) printing in the reprint mode (step P1).
The current line number data of the line number memory 22e is set to "01" (step P2), and it is determined whether or not the arithmetic operation data stored in the arithmetic data memory 22d in association with the current line number "01" is arithmetic operation data including numerical value data and arithmetic data or tax-containing (or non-tax-containing) data (step P3).
Here, it is determined that the arithmetic operation data which is associated with the current line number "01" and registered in the arithmetic data memory 22d (see (B) in fig. 4) is arithmetic operation data including numerical value data "300" and tax-containing data (tax operation 1 data) [ tax + ] (yes in step P3).
Then, as tax calculation data corresponding to the numerical data "300" and the tax-containing data [ tax + ], the printing unit 13 prints the numerical data (without tax data) "300" and without tax label "-T", the tax rate data "8" and tax label "% T", the tax data "24" and tax label "T", the tax-containing data (tax calculation 1 result data) "324" and with tax label "+ T" on the recording paper P (step P4).
Thereafter, it is determined whether or not there is arithmetic operation data associated with the next line number in the arithmetic data memory 22d (refer to (B) in fig. 4) (step P8). Here, it is determined that there is operation data (including tax data [ tax + ]) associated with the next line number "02" (yes in step P8), the current line number "01" of the line number memory 22e is (+1) and "02" is entered (step P9).
Then, it is determined that the arithmetic operation data associated with the current line number "02" and registered in the arithmetic data memory 22d (see (B) in fig. 4) is tax-containing data (tax operation 1 data) [ tax + ], and is neither arithmetic operation data including numerical value data and operator data nor arithmetic operation data including numerical value data and tax-containing (or non-tax-containing) data (step P3 (no)). In addition, since the arithmetic operation data associated with the previous line number "01" and the arithmetic operation data associated with the current line number "02" both include tax data (tax operation 1 data) [ tax + ], it is determined as continuous tax operation data (step P5 (yes)). In this case, printing (suppressing printing) on the recording paper P is not performed (step P6).
Thereafter, as described above, even when the current line number "02" is updated to "03" → "04" (steps P8 (yes), P9), since it is determined that the arithmetic operation data associated with each line number is continuous tax operation data (steps P3 (no), P5 (yes)), the printing (the print suppression) on the recording paper P is not performed (step P6).
Thus, even after correcting a part of the series of operation data subjected to the tax operation by the tax-containing operation (or non-tax operation), by operating the [ reprint ] (registered data printing) key 11g, it is possible to easily print non-tax amount data (-T), tax rate data (% T), tax amount data (T), and tax amount-containing data (+ T) corresponding to the corrected result data of the tax-containing operation on the recording sheet P.
At this time, since the registration data print start mark ". cndot. cndot." is printed at the head of the recording paper P, the user can clearly distinguish the normal print (normal print start mark ". cndot. cndot.) corresponding to the operation of the [ CA ] key 11h in the print mode (ON) and confirm that the corrected registration data is printed corresponding to the operation of the [ reprint ] key.
In addition, when it is determined that the arithmetic operation data stored in the arithmetic data memory 22d in association with the current line number is neither arithmetic operation data including numerical value data and arithmetic data or tax-containing (or tax-free) data (no in step P3) nor continuous tax arithmetic data (no in step P5), the arithmetic operation data stored in association with the current line number is printed (step P7).
In the second embodiment described with reference to fig. 12, for example, the processing of repeatedly operating the [ tax + ] (tax-inclusive operation: 1) key 11b and displaying it as tax-inclusive data "216" → tax-inclusive data "16" → tax-inclusive data "216" after inputting numerical data "200" that is a commodity price (tax-exclusive), and then operating the [ tax- ] (tax-exclusive operation: tax operation 2) key 11c and displaying tax-exclusive data "200" is described in accordance with the processing of steps S10 to S23 shown in fig. 6 and the processing of steps S41 to S43 shown in fig. 7.
On the other hand, for example, after numerical data, which is a commodity price (including a tax amount), is input, the processing of repeatedly operating the [ tax- ] (non-tax operation: tax operation 2) key 11c and displaying the non-tax amount data → the non-tax amount data and then operating the [ tax + ] (non-tax operation: tax operation 1) key 11b and displaying the tax amount data is performed, and only the processing of "tax" [ tax + ] and "non-tax" [ tax- ] is reversed and the same as the above-described processing, so that the processing is performed in accordance with the steps S27 to S40 shown in fig. 7 and the steps S24 to S26 shown in fig. 6.
Thus, according to the desktop electronic calculator 10 of the second embodiment having the above configuration, when the input numerical data and the tax-containing data (or non-tax data) corresponding to the operation of the tax operator key ([ tax + ] (inclusive) key or [ tax- ] (non-tax) key) are registered in the operation data memory 22d as the operation data associated with the row number data updated in sequence, and the registration data confirmation key ([ ] key 11d or [. DELTA ] key 11e) is operated, the registered operation data are called in sequence from the operation data associated with the row number data at the beginning (or end) and the tax-containing data (or non-tax data) and the tax amount data corresponding to the called operation data are displayed in sequence each time the key is operated. When the [ correction ] (correction) key 11f is operated, the mode is changed to the correction mode, and the numerical data including the tax amount data (or not including the tax amount data) in the display can be corrected. Then, when the [ reprint ] (registered data printing) key 11g is operated, tax amount-free data (-T), tax rate data (% T), tax amount data (T), and tax amount-containing data (+ T) corresponding to the corrected numerical value data are printed on the recording paper P. In the state in which the correction operation of the arithmetic operation data is in progress, even when the [ reprint ] (registered data printing) key 11g is operated, no printing is performed, and thus, redundant printing is prevented.
This makes it possible to easily confirm and modify the content of the tax operation, and to prevent unnecessary printing and save money.
In addition, as programs executable by the computer, the methods of the processes of the desktop electronic calculator 10 described in the embodiments, that is, the methods of the calculation data printing process shown in the flowcharts of fig. 5 to 9 and the registration data printing process shown in the flowchart of fig. 10 can be widely stored in media of external storage devices such as memory cards (ROM cards, RAM cards, and the like), magnetic disks (floppy disks (registered trademark), hard disks, and the like), optical disks (CD-ROMs, DVDs, and the like), semiconductor memories, and the like. The Computer (CPU) having the electronic arithmetic unit with the printing function reads a program stored in a medium of the external storage device into the storage device, and controls the operation by the read program, thereby realizing the arithmetic data printing function described in each of the above embodiments and executing the same processing by the above method.
The data of the program for realizing each method may be transmitted as a program code on a communication network (N), or the program data may be introduced from a computer device (program server) connected to the communication network (N) to an electronic arithmetic unit having a printing function and stored in a storage device, thereby realizing the arithmetic data printing function.
The invention of the present application is not limited to the above embodiments, and various modifications can be made in the implementation stage without departing from the gist thereof. Further, the embodiments described above include inventions at various stages, and various inventions can be obtained by appropriately combining a plurality of disclosed structural elements. For example, even if some of the constituent elements shown in the respective embodiments are deleted or some of the constituent elements are combined in different forms, if at least one of the problems described in the technical problem section is effective, an invention can be obtained as a structure in which the constituent elements are deleted or combined.
