Example 1
FIG. 4 is a first embodiment of the calculation data printing process, and a display corresponding to a user operation when the print data does not change due to the rounding process even if the numerical value of the calculation data is corrected in the PRINT mode ON state -It is a figure which shows printing and calculation operation.

  In the first embodiment, the print mode ON setting data is stored when the print mode switch 11a is at the "PRINT" position, the round (rounding mode) switch 11b is at the "5/4" position, and the decimal point is set. An operation in a state where setting data “rounded off” and “rounded digit: 2” is stored when the designation switch 11c is in the position “2” will be described.

  As shown in FIG. 4A, after the clear all key [CA] is input in response to a user operation of the key input unit 11, “33.334” [+ =] “33.325” [+ = ] Is input, the input calculation data is stored in the calculation data storage area 22f each time the [+ =] key is input. Then, as shown in FIGS. 4D1 to 4D3, calculation according to the setting data of the rounding mode (“rounding off” “rounding digit: 2”) is executed, and FIG. 4B1 → B2). As shown, the calculation data of the calculation result is displayed on the display unit 12 as “33.33” (rounding calculation result of 33.334) → “66.66” (rounding calculation result of 33.33 + 33.325). (Steps S3 to S5).

  At this time, since the print mode ON setting data is stored in the PRINT mode storage area 22b, as shown in FIG. 4 (C1), the printing unit 13 causes the [CA] key and [+ = ] Key is entered, “····· CA” “33.33+ (rounding calculation result of 33.334)” “33.33+ (rounding calculation result of 33.325)” and recording paper P sequentially (Step S6 (Yes) → S7).

  Here, when the total key [*] is input, the calculation data (33.33 + 33.325 rounding calculation result) “66.66” of the calculation result calculated as shown in FIG. As shown in FIG. 4 (B3), it is displayed on the display unit 12 (steps S3 to S5).

  Then, “66.66 *” is printed on the recording paper P by the printing unit 13 (Step S6 (Yes) → S7).

  In addition, in the calculation data input / registration / calculation / calculation result display according to the steps S3 to S5, if the print mode OFF setting data is stored in the PRINT mode storage area 22b (step S6 (No )), The data of the unprinted flag ON is stored in the unprinted flag storage area 22c, and the unprinted symbol “NOT PRINTED” is displayed on the display unit 12 (step S8).

  Here, in order to confirm the series of calculations, as shown in FIG. 4 (A), the input calculation data call key [▽] is input once. Then, the head of the series of calculation data (input data) “33.334+” “33.325+” and (registered calculation result data) “66.66 *” stored in the calculation data storage area 22f. Calculation data (input data) “33.334+” in the row “01” is called and displayed on the display unit 12 together with the verification symbol “REV” as shown in FIG. 4 (B4).

  In order to correct the calculation data (input data) “33.334+” of the first line “01” displayed on the display unit 12, a correction instruction key [CORRECT] is input as shown in FIG. When the calculation data corrected for the third and fourth digits after the decimal point is input as “33.3321” [+ =], as shown in FIG. 4 (B5), the corrected calculation data “33.3321+” Is displayed on the display unit 12 together with the correction symbol “CRT” (step S9 (Yes) → S10).

  Then, among the series of calculation data stored in the calculation data storage area 22f, as shown in FIG. 4 (D4), the calculation data “33.3321+” up to the corrected first row “01” is Print data “33.33”, which is recalculated according to the rounding mode setting data (“rounded off” and “rounded digit: 2”), and the calculation data of the calculation result is printed according to the previous calculation (before correction). It is compared with the data “33.33” (step S11).

  Here, the calculation data “33.3321” input this time (after correction) is different from the calculation data “33.334” input previously (before correction), but the calculation data (print data) of the calculation result is different. According to the rounding mode (“rounding off” “rounding digit: 2”), “33.33” is obtained, which is the same as the previous calculation data (print data).

  For this reason, it is determined that there is no change (difference) in the print data (printed) (step S12 (No)), the data of the unprinted flag OFF is stored in the unprinted flag storage area 22c, and FIG. 4 (B5). As shown, a printed symbol “PRINTED” is displayed on the display unit 12 (step S13).

  By displaying the printed symbol “PRINTED”, the user can easily know that there is no change (difference) in the recalculated calculation data (print data) even if the previously input calculation data is corrected. Can do.

  At this time, even if the [PRINT] key is input, since the unprinted flag OFF data is stored in the unprinted flag storage area 22c, the series of calculation data is not reprinted (step S17). (Yes) → S18 (No)). As a result, useless printing with the same print data can be prevented and printing can be saved.

  On the other hand, even when the unprinted flag is OFF, when the recording paper P on which the same calculation data is printed is desired (for example, to save), reprinting is performed by simultaneously pressing the [RE] + [PRINT] key. (Step S19 (Yes)), as shown in FIGS. 4 (B6) to (B8), a series of corrected calculation data “33.3321+” stored in the calculation data storage area 22f. “33.325+” is recalculated from the first line, and as shown in FIG. 4C2, each calculation data associated with the recalculation is sequentially printed on the recording paper P by the printing unit 13 in the same manner as described above. Is output (step S20).

  If the unprinted flag is OFF, the calculation data is not reprinted even if the [PRINT] key is input (step S17 (Yes) → S18 (No)). In response to the first input of the [PRINT] key, a confirmation message “RE PRINT?” Is displayed on the display unit 12 as shown in FIG. (Step S18a).

  Then, in response to the second input of the [PRINT] key, a series of calculations stored in the calculation data storage area 22f as in the case shown in FIGS. 4 (B6) to (B8) (C2). The data may be recalculated, and the calculation data associated with the recalculation may be sequentially printed on the recording paper P by the printing unit 13 (step S18b (Yes) → S20).

  FIG. 5 is a first embodiment of the calculation data printing process, and shows a display / printing / calculation operation according to a user operation when the print data changes when the numerical value of the calculation data is modified in the PRINT mode ON state. FIG.

  First, as shown in FIG. 5 (A), a series of calculation data “123.454” [+ =] “987.645” [+ =] input in response to a user's operation is shown in FIG. As shown in (D3), when the calculation is executed in accordance with the rounding mode setting data ("rounded off", "rounded digit: 2") and the total key [*] is input, (B1) to (B1) in FIG. As shown in B3), the calculation data of the calculation results sequentially calculated are “123.45+ (rounding calculation result of 123.454)” “1111.10+ (rounding calculation result of 123.45 + 987.645)” “1111. 10 (total display: rounding calculation result of 123.45 + 987.645) ”is displayed on the display unit 12 (steps S3 to S5).

  Further, as shown in FIG. 5 (C1), the calculation data of the calculation result are “····· CA” “123.45+” “987.65+” “1, 111.10 *” and the printing unit 13 sequentially. Is printed on the recording paper P (step S6 (Yes) → S7).

  Here, as shown in FIG. 5A, the input calculation data call key [キ ー] is input twice, and the series of calculation data (input data) “123.454+” “987.645+”, (Registered calculation result data) The calculation data (input data) “987.645+” of the second line “02” of “1111.10 *” is called, and the verification symbol is displayed as shown in FIG. 5 (B4). It is displayed on the display unit 12 together with “REV”.

  When the [CORRECT] key is input to instruct correction, and the corrected calculation data “987.654” [+ =] is input, as shown in FIG. 5 (D4), the corrected second line “02” Calculation data (input data) “123.454+” and “987.654+” up to “” are recalculated according to the setting data of the rounding mode (“rounded off” “rounding digit: 2”), and the calculation result Print data “987.65” is compared with print data “987.65” corresponding to the previous calculation (before correction) (steps S9 to S11).

  Here, the calculation data “987.654” input this time (after correction) is different from the calculation data “987.645” input previously (before correction), but the calculation data (print data) of the calculation result is different. According to the rounding mode (“rounding off” “rounding digit: 2”), “987.65” is obtained, which is the same as the previous calculation data (print data). For this reason, as described above, it is determined that there is no change (difference) in the print data (printed) (step S12 (No)), the unprinted flag is turned OFF, and the display unit 12 is displayed as shown in FIG. 5 (B5). The printed symbol “PRINTED” is displayed (step S13).

  Subsequently, as shown in FIG. 5A, the call key [Δ] (return) is input once, and the calculation data (input data) “123” of the first row “01” in the series of calculation data. .454+ ”is displayed and displayed on the display unit 12 together with the verification symbol“ REV ”as shown in FIG.

  When the [CORRECT] key is input to instruct correction, and the corrected calculation data “123.456” [+ =] is input, as shown in FIG. 5 (D5), the corrected first line “01” The calculation data “123.456+” up to “” is recalculated in accordance with the rounding mode setting data (“rounded off” “rounding digit: 2”) as described above, and print data “123. 46 "is compared with the print data" 123.45 "corresponding to the previous calculation (before correction) (steps S9 to S11).

  Then, since the calculation data (print data) “123.46” of the current (after correction) calculation result is different from the previous calculation data “123.45”, it is determined that the print data has changed (unprinted) ( In step S12 (Yes), the unprinted flag ON data is stored in the unprinted flag storage area 22c, and the unprinted symbol “NOT PRINTED” is displayed on the display unit 12 as shown in FIG. Step S14).

  By displaying the unprinted symbol “NOT Printed”, the user can easily know that there is no change (difference) in the recalculated calculation data (print data) by correcting the previously input calculation data. be able to.

  When the [PRINT] key is input, based on the fact that unprinted flag ON data is stored in the unprinted flag storage area 22c (step S18 (Yes)), FIG. 5 (B8) to (B10). As shown in FIG. 5, the corrected series of calculation data “123.456+” and “987.654+” stored in the calculation data storage area 22f are recalculated from the first row, and are shown in FIG. 5 (C2). As described above, the calculation data “123.46+”, “987.65+”, “1, 111.11 *” of each calculation result accompanying the recalculation are sequentially printed on the recording paper P by the printing unit 13 and output (Step S20). ).

  Even if the [RE] + [PRINT] key is pressed at the same time and reprinting is instructed (step S19 (Yes)), the calculation data “123.46+” of each calculation result accompanying the recalculation is the same as described above. "987.65+" and "1, 111.11 *" are sequentially printed on the recording paper P by the printing unit 13 and output (step S20).

  As a result, when the calculation data is corrected, only when the calculation data (print data) of the calculation result is different from the calculation data (print data) before the correction, after the correction by the [PRINT] key. Since the calculation data can be reprinted, useless printing can be prevented and printing can be saved.

  Currently, the calculator 10 stores the print mode ON setting data when the print mode switch 11a is at the "PRINT" position, the round (rounding mode) switch 11b is at the "5/4" position, and the decimal point. Since the designation switch 11c is in the “0” position, the setting data “rounded off” and “rounded digit: 0” are stored.

  As shown in FIG. 6A, when “251” [×] “3” [=] [TAX +] is input according to the user operation of the key input unit 11, the input calculation data is [× ] [=] [TAX + (tax rate 8%)] key is stored in the calculation data storage area 22f each time a key is input. Then, as shown in FIG. 6 (D1), calculation according to the setting data of the rounding mode (“rounded off” “rounding digit: 0”) is executed, as shown in FIGS. 6 (B1) to (B4). Then, the calculation data of the calculation result is displayed on the display unit 12 as “251” → “3” → “753” → “813” (steps S3 to S5).

  Further, as shown in FIG. 6 (C1), the calculation data of the calculation result is “····· CA” “251. ×” “3. =” “753.” “753.-T” “8. % T "" 60.T "" 813. + T "are sequentially printed on the recording paper P by the printing unit 13 (step S6 (Yes) → S7).

  Here, the tax amount is added by “rounding off” and “rounding digit: 0”, but the round (rounding mode) switch 11b is switched to the “CUT” position in order to recalculate with “rounded down” after the decimal point. (Step S15 (Yes)), it is determined whether the calculation data to be recalculated is stored in the calculation data storage area 22f (Step S16).

  When it is determined that the calculation data corresponding to the series of calculations “251” [×] to [TAX +] is stored in the calculation data storage area 22f (step S16 (Yes)), the series of calculations. As shown in FIG. 6 (D2), the data is recalculated according to the switched rounding mode setting data (“truncated” after the decimal point), and the print data “813” that is the result of the calculation is executed. Is compared with the print data “813” corresponding to the previous calculation (before the rounding mode switching) (step S11).

  Here, the setting data of the rounding mode has been switched from “rounded off” to “rounded down” after the decimal point, but the calculation data (print data) of the calculation result is “813” and the previous calculation data (print data). Be the same. For this reason, it is determined that there is no change (difference) in the print data (printed) (step S12 (No)), the data of the unprinted flag OFF is stored in the unprinted flag storage area 22c, and FIG. 6 (B5). As shown, a printed symbol “PRINTED” is displayed on the display unit 12 (step S13).

  By displaying the printed symbol “PRINTED”, the user can easily know that there is no change (difference) in the recalculated calculation data (print data) even if the rounding mode setting data is changed. be able to.

  Similarly to the case shown in FIG. 4, even if the [PRINT] key is input, the unprinted flag OFF data is stored in the unprinted flag storage area 22c. Reprinting is not performed (step S17 (Yes) → S18 (No)). As a result, useless printing with the same print data can be prevented and printing can be saved.

  If the [RE] + [PRINT] key is pressed simultaneously (step S19 (Yes)), as shown in FIGS. 6 (B6) to (B9), a series of calculation data after the rounding mode switching is obtained. As shown in FIG. 6 (C2), the calculation data associated with the recalculation can be printed on the recording paper P by the printing unit 13 as described above (step S20).

  Similarly to the case shown in FIG. 4, in response to the first input of the [PRINT] key, as shown in FIG. 6 (B10), a confirmation message as to whether or not reprinting has been performed. “RE PRINT?” Is displayed (step S18a), the series of calculation data is recalculated in response to the second input of the [PRINT] key, and the calculation data associated with the recalculation is sequentially recorded on the recording paper P. (Step S18b (Yes) → S20).

  FIG. 7 is a second embodiment of the calculation data printing process, and when the setting of the rounding mode is changed while the PRINT mode is ON, the display / printing / calculation corresponding to the user operation when the print data changes (differs). It is a figure which shows operation | movement.

  Here, in a state where the rounding mode is set to “round off” after the decimal point, a series of calculation data [CA] “253” [×] “3” [=] [TAX +] is input according to the user operation. Similarly to the case shown in FIG. 6, the calculation according to the calculation data is executed (see FIG. 7 (D1)). Then, the calculation result data is sequentially displayed on the display unit 12 (see FIGS. 7B1 to B4) and printed on the recording paper P by the printing unit 13 (see FIG. 7C1) (steps S3 to S7). ).

  Here, when the round (rounding mode) switch 11b is switched to the “CUT” position (step S15 (Yes)) in order to recalculate with “rounded down” after the decimal point (step S15 (Yes)), FIG. As shown in D2), the recalculation is executed in accordance with the switched rounding mode setting data ("rounded down" after the decimal point), and the print data "819" which is the calculation result data is the previous time (rounding mode switching). It is compared with the print data “820” corresponding to the previous calculation (step S11).

  Then, since the calculation data (print data) “819” of the current calculation result (after switching the rounding mode) is different from the previous calculation data “820”, it is determined that there is a change (difference) in the print data (unprinted). (Step S12 (Yes)), the data of the unprinted flag ON is stored in the unprinted flag storage area 22c, and the unprinted symbol “NOT PRINTED” is displayed on the display unit 12 as shown in FIG. 7 (B5). (Step S14).

  By displaying this unprinted symbol “NOT PRINTED”, the user can easily know that there is a change (difference) in the calculation data (print data) of the calculation result obtained by switching the rounding mode and recalculating.

  Then, as in the case shown in FIG. 5, when the [PRINT] key is input, as shown in FIG. 7 (B6) to (B9) according to the data of the unprinted flag ON (step S18 (Yes)). In addition, the series of calculation data after the rounding mode switching is recalculated from the first row, and as shown in FIG. 7 (C2), calculation data “253. ×” to “253.x” to “ 819. + T ″ are sequentially printed on the recording paper P (step S20).

  If the [RE] + [PRINT] key is pressed simultaneously (step S19 (Yes)), the calculation data of each calculation result accompanying the recalculation can be sequentially printed on the recording paper P (step S20). .

  As a result, when the rounding mode is switched, only after the calculation data (print data) of the calculation result is different from the calculation data (print data) before the switching, after correction by the [PRINT] key. Since the calculation data can be reprinted, useless printing can be prevented and printing can be saved.

  Therefore, according to the calculation data printing function of the calculator 10 with a printer having the above-described configuration, a rounding mode of “rounded down”, “rounded up”, or “rounded off” is set in accordance with a user operation, and a calculation composed of a numerical value and a calculation function is set. When the data is input, each time the calculation data is input, the calculation data is stored in the calculation data storage area 22f in the input order, and the calculation according to the calculation data is performed according to the setting contents of the rounding mode. The series of calculation data including the calculation result is sequentially printed on the recording paper P by the printing unit 13. Then, when any calculation data in the series of calculation data stored in the calculation data storage area 22f is corrected or the setting of the rounding mode is changed, the corrected calculation data (or the changed rounding mode) Recalculation is performed, and it is determined whether the recalculated calculation data is different from the printed calculation data. If the calculation data is different, the unprinted flag in the unprinted flag storage area 22c is turned on and the calculated data is not yet determined. The print symbol “NOT PRINTED” is displayed on the display unit 12, and if not different, the unprinted flag is turned OFF and the printed symbol “PRINTED” is displayed.

  When the unprinted flag is ON ("NOT PRTED" is displayed), the calculation data is corrected (or the rounding mode is changed) regardless of whether the [PRINT] key is input or the [RE] + [PRINT] key is simultaneously input. A series of calculation data including the calculation result recalculated in (after) is sequentially printed on the recording paper P by the printing unit 13.

  When the unprinted flag is OFF ("PRINTED" display), even if the [PRINT] key is input, the recalculated series of calculation data is not printed, and the [RE] + [PRINT] key is pressed. Only when simultaneously input, the recalculated series of calculation data is reprinted.

  As a result, even if a series of calculation data once calculated and printed is corrected by verification or recalculated after changing the rounding mode, there is a change (difference) in the recalculated calculation result according to the setting of the rounding mode. If not, reprinting with the [PRINT] key is prohibited, and reprinting is performed only when the [RE] + [PRINT] key is pressed at the same time, thus preventing unnecessary printing and saving printing. Is possible.

  It should be noted that each processing method by the calculator 10 with a printer described in each of the embodiments, that is, each method such as calculation data printing processing shown in the flowcharts of FIGS. 3A and 3B can be executed by a computer. As a memory card (ROM card, RAM card, etc.), magnetic disk (floppy (registered trademark) disk, hard disk, etc.), optical disk (CD-ROM, DVD, etc.), external memory, etc. Can be distributed.
