In the desk-top electronic calculator 10, power supply opening (herein, power key 11E is switched when being operated according to user To the position of [conversion] (currency translation)) when, by CPU21, as the processing of the initial setting with the power supply opening, in institute The setting data that printing model (opening) is stored in printing model memory 22b are stated, are deposited in the operational pattern memory 22c The setting data of enrollment mode are stored up, and the data (step S1) of line number " 0 " are stored in the line number memory 22e.

In the state of the printing model (opening), as shown in (A1) in Figure 11, if [PRT] (printing described in operation Pattern) key 11a (step S2 (YES)), then the setting data of the printing model (opening) are switched into printing model (closing) Set data (step S3).

Then, if operation [CA] key 11h (step S4 (YES)), changes the data of the line number and be set as " 0 " (step S5)。

Herein, for example, the coefficient of conversion at " yen " corresponding to basic currency " $ " is 111.2 yen/$, the conversion of " member " In the case that rate is 6.585 yuan/$, as shown in (A2) in Figure 11, due to the known exchange rate of yen corresponding to " member ", therefore head If first input numeric data " 111.2 " (step S8 (YES)), the data quilt (+1) of the line number show so as to be updated to " 01 " It is shown in the display part 12.In addition, the numeric data " 111.2 " inputted is shown in the display part 12.Then, institute The Status Flag for stating Status Flag memory 22f is set to " numerical value input state " (step S9).

Then, if inputting operator data [÷] (step S9a according to the operation of operator key [÷] (division calculation) (YES)), then according to the current line number data " 01 " stored in the line number memory 22e, in the operational data memory 22d Line number " 01 " region in the numeric data " 111.2 " and the operator data [÷] of the input are stored and stepped on Remember (step S9b).

Then, if input numeric data " 6.585 " (step S8 (YES)), as described above, the data of line number by (+ 1) so as to be updated to " 02 ", and it is shown in the display part 12 (step S9).

Then, if inputting operator data [+=] (step according to the operation of operator key [+=] (additional calculation adds up to) S9a (YES)), then according to the current line number data " 02 " stored in the line number memory 22e, in the operational data memory The numeric data " 6.585 " of the input and the operator data [+=] are stored in the region of 22d line number " 02 " And register (step S9b).If without the operation of operator key [+=] (additional calculation adds up to), it is transferred to shown in Fig. 6 2. (step S9a (no)).

After step S9b, arithmetic operation data " 111.2 [÷] with being registered in the operational data memory 22d are performed The corresponding computing of 6.585 [+=] ", and in fortune of the display part 12 display as the exchange rate of yen of " member " described in corresponding to Calculate result data " 16.886 ... " (yen/member) (step S9c).

Herein, due to the state in the printing model (closing), therefore without the arithmetic operation data The printing (step S9d (no)) of " 111.2 [÷] 6.585 [+=] " and operation result data " 16.886 ... ".

In addition, (the step S9d in the case where being judged as the state in printing model (opening) by the CPU21 (YES)), whenever registering arithmetic operation data " 111.2 [÷] " and " 6.585 [+=] " in the operational data memory 22d When, print the arithmetic operation data and its operation result data successively to recording sheet P by the Printing Department 13 " 16.886 ... " (step S9e).

Next, in order to set the coefficient of conversion of " yen " and " member ", as shown in (A3) in Figure 11, if operating [CA] again Key 11h (step S4 (YES)), then change the data of the line number and be set as " 0 " (step S5).

Herein, after the operation (step S4 (YES)) of [CA] key 11h described in progress, if as shown in figure 8, to the [% (setting)] (setting coefficient of conversion) key 11i carry out more than 3 seconds long-press operate (step S10a (YES)), then be transferred to step S10b.

Then, as shown in (A4) in Figure 11, as the coefficient of conversion of " yen ", input and show numeric data " 111.2 " (step S10b (YES) → S10d), as shown in (A5) in Figure 11, if operation [C1] (currency 1) key 11k (steps S10e (YES)), then in the coefficient of conversion memory 22g register " yen " coefficient of conversion [C1：111.2 yen/$] (step S10g)。

As shown in (A3) in above-mentioned Figure 11, (A4), in the long-press from [% (setting)] (setting coefficient of conversion) the key 11i Operation (step S10a (YES)) is untill before [C1] (currency 1) key 11k described in operation in the coefficient of conversion setting of (step S10d) In the state of, even in the case where operating described [reprinting] (registration data printing) key 11g (step S10c (YES)), Without any printing, so as to prevent unnecessary printing.

Hereafter, in the same manner as the setting of the coefficient of conversion of " yen ", in order to set the coefficient of conversion of " member ", in Figure 11 (A6) shown in, as [% (setting)] (setting coefficient of conversion) key 11i (step S10a (YES)) described in long-press operation again, input is simultaneously Numeric data " 6.585 " (step S10b (YES) → S10d) is shown, as operation [C2] (currency 2) key 11l (step S10e (YES)) When, the coefficient of conversion [C2 of registration " member " in the coefficient of conversion memory 22g：6.585 yuan/$] (step S10g).

Herein, as described above, (step is being operated from the long-press of [% (setting)] (setting coefficient of conversion) the key 11i S10a (YES)) in coefficient of conversion setting of the state untill the state (step S10d) for not operating [C2] (currency 2) key 11l, Even in the case where operating described [reprinting] (registration data printing) key 11g (step S10f (YES)), also without appointing What prints, so as to prevent unnecessary printing.

As shown in (A6) in described Figure 11, it is registered in the coefficient of conversion in by described in " yen " or the coefficient of conversion of " member " and deposits After reservoir 22g, by 1.~5. operate (step S57 (YES)) in the case of described [reprinting] (registration data printing) key 11g, If performing registration data printing treatment SP (Fig. 9), but (registration data printing) key 11g is not operated and [reprinted], be then transferred to (step S58))。

In registration data printing treatment SP, as shown in (A3) in Figure 11, due to the operation based on [CA] the key 11h To remove the arithmetic operation data of the operational data memory 22d, as shown in (B1) in Figure 11, when [being reprinted] described in operation During (registration data printing) key 11g, printed again due to having printed to represent to be in recording sheet P merely by the Printing Department 13 [CA] under pattern (all removes) registration data printing beginning label " the 0 " (step of the situation of printing Rapid P1), even therefore the current line number data relative to the operational data memory 22d is updated to more than " 01 ", The operational datas such as any arithmetic operation data, operation result data (step P2~P8 (no) → return) will not be printed.

Here, it is assumed that Japanese has bought 4 300 yuan of commodity in the shop that can use Chinese member, and described buy Commodity transport to Japan freight charges be 100 yuan, total volume including the freight charges is converted into yen be how many progress computing.

As shown in (A7) in Figure 11, after the operation (step S4 (YES), step S6 (no)) of [CA] the key 11h, If being operated according to the user of the value key, the numeric data " 300 " (step S8 (YES)) of the price as the commodity is inputted, Then the data of the line number are updated to " 01 " by (+1), are shown in the display part 12.In addition, the numbered inputted The display part 12 is shown according to " 300 ".Then, the Status Flag of the Status Flag memory 22f is set to " numerical value Input state " (step S9).

Then, if inputting operator data [×] (step S9a according to the operation of operator key [×] (multiplication calculating) (YES)), then according to the current line number data " 01 " stored in the line number memory 22e, in the operational data memory 22d In the region of the line number " 01 " of (reference picture 3), store and register the numeric data " 300 " of the input and the operator data [×] (step S9b, step S9c, step S9d (no)).

Then, as shown in (A8) in Figure 11, if numeric data " the 4 " (step of buying quantity of the input as the commodity Rapid S8 (YES)), then as described above, the data of line number are updated to " 02 " by (+1), and are shown in the display part 12 (step Rapid S9).

Then, if inputting operator data [+=] (step according to the operation of operator key [+=] (additional calculation adds up to) Rapid S9a (YES)), then according to the current line number data " 02 " stored in the line number memory 22e, stored in the operational data In the region of device 22d (reference picture 3) line number " 02 ", store and register the numeric data " 4 " of the input and the operator Data [+=] (step S9b).

Then, arithmetic operation data " 300 [×] 4 [+=] " phase with being registered in the operational data memory 22d is performed Corresponding computing, and show the operation result data " 1200 " for total volume that commodity are bought as described in the display part 12 (step S9c).

Then, as shown in (A9) in Figure 11, if the numeric data " 100 " of the freight charges of commodity is bought in input as described in (step S8 (YES)), then as described above, the data of line number are updated to " 03 " by (+1), and are shown in the display part 12 (step S9).

Then, if inputting operator data [+=] (step according to the operation of operator key [+=] (additional calculation adds up to) S9a (YES)), then as described above, according to the current line number data " 03 " stored in line number memory 22e, in the computing In the region of data storage 22d (reference picture 3) line number " 03 ", store and register the input numeric data " 100 " and The operator data [+=] (step S9b).

Then, perform corresponding with the arithmetic operation data " 100 [+=] " registered in the operational data memory 22d Computing, and the display part 12 display as include described in buy commodity freight charges total volume operation result data " 1300 " (step S9c).

Herein, if by [*] (total) key 11n operation, total volume " 1300 of the freight charges for buying commodity will be included Member " is appointed as the object of conversion, then is transferred to 8. (step S9f (YES)) shown in Fig. 8.In addition, in step S9f, if not operating [*] (total) key 11n, then be transferred to step S9d.In order to by total volume " 1300 yuan " from " member " be scaled to " yen " when, it is first First, as shown in (A10) in Figure 11, (the step when [C2] (currency 2) key 11l of the coefficient of conversion to setting " member " is operated Rapid S10h (YES)), the data of the line number are updated to " 04 " by (+1), and are shown.Then, by shown numbered According to the coefficient of conversion [C2 for " member " registered in " 1300 " divided by the coefficient of conversion memory 22g：6.585 yuan/$], and calculate and change It is counted as total volume " 197.4183 ... " (step S10i) of basic currency " $ ".

Then, according to the current line number data " 04 " stored in the line number memory 22e, stored in the operational data It is that object is simultaneously divided by described to the numeric data " 1300 " with the display in the region of device 22d (reference picture 3) line number " 04 " The arithmetic operation data " [÷] [C2] " of coefficient of conversion [C2] are stored and registered (step S10j).

" as operational data and are printed (S10l)。

In addition, in the present first embodiment, due to being set as printing model (closing), therefore without according to the step Rapid S10l printing.

In addition, as shown in (A10) in above-mentioned Figure 11, (A11), in the operation (step from [C2] (currency 2) the key 11l Rapid S10h (YES)) until the state in the scale operation untill (step S10j) before [C1] (currency 1) key 11k described in operation Under, even in the case where operating described [reprinting] (registration data printing) key 11g (step S10n (YES)), also without Any printing, so as to prevent unnecessary printing.

Also, after this, as shown in (A11) in Figure 11, in [C1] (currency of the coefficient of conversion to setting " yen " 1) when key 11k is operated (step S10m (YES)), the basic currency " $ " numeric data will be converted into " 197.4183 ... " $ is multiplied by the coefficient of conversion [C1 of " yen " registered in the coefficient of conversion memory 22g：111.2 yen/$], And calculate total volume " 21953 " yen (step S10o) for being converted into " yen ".

Then, the data of the line number are updated to " 05 " and shown by (+1), and are stored in the operational data In the region of device 22d (reference picture 3) line number " 05 ", to be converted into the numeric data of " dollar " from " member " " 197.4183 ... " $ is that the arithmetic operation data " [×] [C1] " of the coefficient of conversion [C1] of object divided by " yen " are deposited Store up and register (step S10p).

Then, make in the display part 12 display to be converted into the numeric data of " dollar " from " member " " 197.4183 ... " $ is operation result data " 21953 " (step that object is multiplied by after the coefficient of conversion [C1] of " yen " S10q)。

Herein, for example, in the case where being judged as the state in printing model (opening) (step S10r (YES)), as above State shown in (B2) PR1 in Figure 11, and then the fortune associated with the line number " 01 "~" 04 " being printed on recording sheet P Calculate the operational formula part " 300 [×] 4 [+=] 100 [+=] " of operation data and its operation result data " 1300 " and make The operation result data " 1300 " divided by the coefficient of conversion [C2 of " member "：6.585 yuan/$] arithmetic operation data operational formula Part and its operation result data " 197.4183 ... $ ", it is described basic to making to be converted into as shown in (B2) PR2 in Figure 11 The numeric data " 197.4183 ... " of currency " $ " is multiplied by the coefficient of conversion [C1 of " yen "：111.2 yen/$] computing behaviour The operational formula part and its operation result data " 21953 " for making data are printed (step 10s).

In addition, in the present first embodiment, due to being set as printing model (closing), therefore it will not carry out according to described The printing of the operational data such as the operational formula part of step S10s arithmetic operation data or operation result data.

Then, as shown in (A11) in Figure 11, terminating according to from [C2] (currency 2) the key 11l to [C1] (currency 1) key 11k operation after the currency translation of total volume " 21953 " of total volume " 1300 " to " yen " of " member ", warp Cross 1.~5., (registration data printing) key 11g (step S57 (YES) → SP) [is reprinted] described in operation, now perform Figure 10 shown in Registration data printing treatment.

If starting the registration data printing treatment, as shown in (B2) in Figure 11, by the Printing Department 13 to record Paper P printing registration data printing beginning labels " 0 ", it represents (complete in [CA] reprinted under pattern Portion remove) printing situation (step P1).

Then, the current line number data of the line number memory 22e are set to " 01 " (step P2), and judge with it is described Whether the arithmetic operation data that current line number " 01 " is associated and is registered in the operational data memory 22d are to include numerical value Operational data (the step of the operational formula part of data, operator data or the arithmetic operation data containing tax (or without tax) data Rapid P3).

Herein, it is judged as associated with current line number " 01 " and is registered in the operational data memory 22d (reference picture 3) In arithmetic operation data be to include arithmetic operation data (the step P3 of numeric data " 300 " and operator data [×] (YES)).

Then, and then printed on the recording sheet P registration data printing beginning label " 0 ", it is relative with the numeric data " 300 " and operator data [×] in recording sheet P printings by the Printing Department 13 The operational data (step P4) answered.

Hereafter, judge in the operational data memory 22d (reference picture 3) with the presence or absence of associated with next line number Arithmetic operation data (step P8).Herein, be judged as existing arithmetic operation data associated with next line number " 02 " (4 [+ =]) (step P8 (YES)), and the current line number " 01 " of the line number memory 22e is updated to " 02 " (step P9) by (+1).

Then, it is judged as associated with current line number " 02 " and is registered in the operational data memory 22d (reference picture 3) Arithmetic operation data as described above, be the arithmetic operation data for including numeric data " 4 " and operator data [+=] (step P3 (YES)), and printed on recording sheet P by the Printing Department 13 with the numeric data " 4 " and operator data [+ =] corresponding operational data and its operation result data " 1200 " (step P4).

Hereafter, also as described above, will be with the operational data memory 22d (references as shown in (B2) in Figure 11 The arithmetic operation data of registration corresponding operational data and its operation result data in each line number " 03 "~" 05 " Fig. 3) Printing is (100 [+]) (1300 [*]) on recording sheet P successively ... (21953 [C]) (step P3, P4, P8, P9).

Thus, even in the state of the printing model (closing), if currency translation terminates, by described in operation [reprinting] (registration data printing) key 11g, a series of arithmetic operation that will easily can be still bought with the adjoint commodity Data and with the corresponding operational formula part of a series of arithmetic operation data of the currency translation and its computing knot Fruit data printing is on recording sheet P.

Therefore, according to the desk-top electronic calculator 10 of the first embodiment of the structure, in printing model (opening) Under state, operational formula part and the fortune of the arithmetic operation data corresponding with user's operation can be printed successively in recording sheet P Result data is calculated, even in the state of printing model (closing), if currency translation terminates, (is stepped on by operating [reprinting] Remember data printing) key 11g, still a series of computing registered in operational data memory 22d can be printed in the lump in recording sheet P The operational formula part of operation data and its operation result data.No matter also, the printing model beats the shape of opening/closing State is how, when the state that the process of currency translation processing is in coefficient of conversion setting or the state in scale operation, by Even if in operating described [reprinting] (registration data printing) key 11g, will not also carry out any printing, thus can prevent it is unnecessary Printing.

Thereby, it is possible to after the operational data to being registered according to arithmetic operation terminates currency translation, operated according to user To be printed, therefore the unnecessary printing repeated due to the printing instruction before end currency translation can be eliminated, and fitted Locality carries out required printing.

(second embodiment)

In this second embodiment, set to being stored with printing model opening in the printing model memory 22b In the state of, corresponding with the tax calculation function action of fixed number illustrates.

Figure 12 be the second embodiment for representing the operational data printing treatment the display corresponding with user's operation/ The figure of printing action.

In the desk-top electronic calculator 10, printing model (opening) is stored with the printing model memory 22b Setting data printing model (opening) in the state of (step S1), for example, as shown in (A1) in Figure 12, if operation [CA] Key 11h (step S4 (YES)), then the data of the line number of the line number memory 22e be set to " 0 " (step S5).Described aobvious Show the symbol " PRT " that numeric data " 0 " is shown in portion 12 and represents the state in the printing model (opening).

Herein, if being judged as the state (step S6 (YES)) in printing model (opening), such as Figure 12 by the CPU21 In (B1) shown in, by the Printing Department 13 to recording sheet P print generally printing beginning label " 0 ", its represent with [CA] (Clear All, all removing) key 11h in the state of the printing model (opening) operates corresponding printing Situation (step S7).

Also, as shown in (A2) in Figure 12, operated according to the user of the value key, for example, being used as commodity in input During numeric data " 200 " of price (being free of the amount of tax to be paid) (step S8 (YES)), the data of the line number are updated to " 01 " by (+1), And the display part 12 is shown in, while the numeric data " 200 " of the input is shown in the display part 12.Also, institute The Status Flag for stating Status Flag memory 22f is set to " numerical value input state " (step S9).

Herein, as shown in (A3) in Figure 12, if [tax+] (computing containing tax described in operation：Tax computing 1) key 11b (steps S10 (YES)), then whether the Status Flag for judging the Status Flag memory 22f is " numerical value input state " (step S11).

If it is " numerical value input state " (step S11 (YES)) to be judged as the Status Flag, stored according to the line number The current line number data " 01 " stored in device 22e, in the operational data memory 22d ((A) in reference picture 4) line number In the region of " 01 ", (storage) described numeric data " 200 " inputted is registered and corresponding to [tax+] (computing containing tax：Tax Computing 1) key 11b contains tax (tax computing 1) data [tax+] (step S12).

Then, execution (is the tax rate in present embodiment for the computing containing tax (tax computing 1) of the numeric data " 200 " 8%) (step S13), and the line number data " 01 " are updated to " 02 " by (+1), and the display part 12 is shown in, with this Meanwhile the data containing the amount of tax to be paid (result data of tax computing 1) " 216 " after the display computing containing tax, and show and contain tax described in expression The symbol " tax+" of volume.Also, the Status Flag of the Status Flag memory 22f is set to that [computing containing tax shows containing the amount of tax to be paid Show state] (step S14).

Herein, if being judged as being stored with the setting data (step of printing model opening in the printing model memory 22b S15 (YES)), and be judged as not printing the operation result data (step S16 (no)) of the computing containing tax (tax computing 1), then As shown in (B1) in Figure 12, the usual printing beginning label " 0 " that is and then printed on the recording sheet P, lead to Cross the Printing Department 13 and print the numeric data (being free of amount of tax to be paid data) " 200 " of the input and without amount of tax to be paid mark in recording sheet P Remember "-T ", in next print line printing tax rate data " 8 " and tax rate mark " %T ", print amount of tax to be paid data in next print line again " 16 " and the amount of tax to be paid mark " T ", in next print line printing data containing the amount of tax to be paid (result data of tax computing 1) " 216 " again and containing the amount of tax to be paid Mark "+T ", be used as the tax computing printed data (step S17) of the computing containing tax.

Herein, as shown in (A4) in Figure 12, if [tax+] (computing containing tax described in operation again：Tax computing 1) key 11b (steps Rapid S10 (YES)), then it is judged as the Status Flag of the Status Flag memory 22f for [amount of tax to be paid that contains of the computing containing tax shows shape State] (step S18 (YES)).

Then, according to the current line number data " 02 " stored in the line number memory 22e, stored in the operational data In the region of device 22d ((A) in reference picture 4) line number " 02 ", store and register corresponding to described [tax+] (computing containing tax：Tax Computing 1) key 11b data containing tax (data of tax computing 1) [tax+] (step S19).

Then, the line number data " 02 " are updated to " 03 " and shown by (+1), in addition, after the display computing containing tax Amount of tax to be paid data " 16 ", and show the symbol " tax " for representing the amount of tax to be paid.Also, the state of the Status Flag memory 22f Mark is set to [amount of tax to be paid dispaly state of the computing containing tax] (step S20).

Herein, further, as shown in (A5) in Figure 12, if [tax+] key 11b (step S10 described in operation again (YES)), then it is [amount of tax to be paid dispaly state of the computing containing tax] (step S21 (YES)) to be judged as the Status Flag.

Then, according to the current line number data " 03 " stored in the line number memory 22e, stored in the operational data In the region of device 22d ((A) in reference picture 4) line number " 03 ", store and register and contain tax corresponding to [tax+] the key 11b Data (data of tax computing 1) [tax+] (step S22).

Also, the line number data " 03 " are updated to " 04 " and shown by (+1), transported in addition, display is described again containing tax The data containing the amount of tax to be paid " 216 " calculated, and show the expression symbol " tax+" containing the amount of tax to be paid.Then, the Status Flag memory 22f Status Flag is set as [dispaly state containing the amount of tax to be paid of the computing containing tax] (step S23) again.

Herein, as shown in (A6) in Figure 12, (tax computing is free of at [tax -] described in operation：Tax computing 2) key 11c when (step Rapid S27 (YES)), if not continuing to input numerical value (step S28 (no)), be judged as the Status Flag for [computing containing tax it is (aobvious Show and contain the amount of tax to be paid) state] (step S41 (YES)).

Then, according to current line number data " 04 ", in the operational data memory 22d ((A) in reference picture 4) row In the region of number " 04 ", store and register and be free of tax data (data of tax computing 2) [tax -] corresponding to [tax -] the key 11c (step S42).

Then, the line number data " 04 " are updated to " 05 " and shown by (+1), in addition, being free of amount of tax to be paid number described in display According to " 200 ", and show and represent the symbol " tax-" for being free of the amount of tax to be paid.Also, the state mark of the Status Flag memory 22f Will is set to and [is free of amount of tax to be paid dispaly state without tax computing] (step S43).

So, when inputting [tax+] (computing containing tax) key 11b described in the numeric data " 200 " and operation, execution contains tax Computing, and data containing the amount of tax to be paid " 216 " and its symbol " tax+" are shown, then [tax+] key 11b described in operation, is now being carried out every time Amount of tax to be paid data " 16 " and its symbol " tax " and data containing the amount of tax to be paid " 216 " and its symbol " tax+" are carried out during the operation alternately aobvious Show, further, when operating [tax -] key 11c, alternately display can be free of amount of tax to be paid data " 200 " and its symbol " tax-".Cause This, easily verifies that the content of tax computing at one's fingertips in display part 12 that can be.

Now, contained according to the input of the numeric data " 200 " and [tax+] (computing containing tax) key 11b operation to perform Tax computing (tax computing 1), and printing tax computing printed data of computing containing tax (tax computing 1) as described on recording sheet P Without amount of tax to be paid data (input data) " 200.-T ", tax rate data " 8.%T ", amount of tax to be paid data " 16.T " and data containing the amount of tax to be paid After (result data of tax computing 2) " 216.+T ", even under the setting state that the printing model is opened, will be to continuing to grasp [tax+] key 11b described in work or [tax -] key 11b is judged and continues as that [computing containing tax (contains tax to the Status Flag Volume shows/amount of tax to be paid shows) state] or [(show without the amount of tax to be paid/amount of tax to be paid show) state without tax computing] judged, as above State shown in (A4)~(A6) in Figure 12, display amount of tax to be paid data " 16 " → data containing the amount of tax to be paid " 216 " → are free of amount of tax to be paid data " 200 ", and without printing treatment during confirmation every time.So as to control the content for unwanted repetition of not repeating print.

It is next, interior for a series of arithmetic operation data that confirm to correspond to the computing containing tax (tax computing 1) Hold, it is described if operating the registration data acknowledgement key ([▽] key 11d) (step S44 (YES)) as shown in (A7) in Figure 12 Operational pattern memory 22c setting data are set to confirm (checking computations) pattern, and the display part 12 are shown described true Recognize the symbol " REV " of pattern.In addition, call go forward side by side associated with the line number " 01 " of the beginning of the operational data memory 22d The arithmetic operation data (numeric data (being free of amount of tax to be paid data) " 200 " and containing tax (tax computing 1) data [tax+]) of row registration, and With being shown in the display part 12 (step S45) together with the line number " 01 ".

Herein, for the numeric data corresponding to the line number " 01 " for showing the display part 12 and having been confirmed (being free of amount of tax to be paid data) " 200 " modify, as shown in (A8) in Figure 12, if [amendment] (amendment) key 11f (steps described in operation Rapid S49 (YES)), then the setting data of the operational pattern memory 22c are set to modification model, and to the display part 12 Show the symbol " CRT " (step S50) of the modification model.

Also, as shown in (A9) in Figure 12, input and show correct numeric data " 300 " (step S51 (YES), S52),, will be with if [amendment] (amendment) key 11f (step S53 (YES)) described in operation again as shown in (A10) in Figure 12 Current line number " 01 " is associated and is stored in the arithmetic operation data of the operational data memory 22d (numeric data (is free of tax Specified number evidence)) " 200 " are replaced into the numeric data " 300 " inputted, and are registered (step S54) (in reference picture 4 (A)、(B)).Then, the symbol " CRT " (step S55) for the modification model for being shown in the display part 12 is eliminated.

In addition, as (A8) and (A9) in described Figure 12 is shown, with the first time from [amendment] (amendment) the key 11f Operate the amendment operation of (step S49 (YES)) arithmetic operation data corresponding untill before second of operation (step S53) In in the state of, even in the case where having operated described [reprinting] (registration data printing) key 11g (step S51a (YES)/ S53a (YES)), also without any printing, so as to prevent unnecessary printing.

Hereafter, as shown in (A11) in Figure 12~(A13), if repeating the registration data acknowledgement key ([▽] key 11d) (step S46 (YES)), then carry out the operation every time, is confirmed whether in the presence of associated simultaneously with next line number of current line number It is registered in the arithmetic operation data (step S47) of the operational data memory 22d.Also, when exist and next line number During associated arithmetic operation data (step S47 (YES)), its arithmetic operation data is called, and show together with next line number It is shown in the display part 12 (step S48).

That is, as shown in (A11) in Figure 12, if operating the registration data acknowledgement key ([▽] key 11d) (under affirmation mode Second), then show revised arithmetic operation data (numeric data that is corresponding with the line number " 01 " and being registered (being free of amount of tax to be paid data) " 300 ", based on the input operation after the input operation by " 200 " before amendment and the number containing tax registered According to (data of tax computing 1) [tax+]) carry out the data containing the amount of tax to be paid (result data of tax computing 1) after computing containing tax (tax computing 1) Symbol " tax+" corresponding to " 324 " and the data containing tax [tax+] corresponding and called with line number " 02 ".In other words, phase For the numeric data " 300 " shown in (A10) in Figure 12, display carries out the number containing tax of the symbol shown in (A10) in Figure 12 Result according to the processing of " tax+" is data containing the amount of tax to be paid " 324 ", and will contain next processing of amount of tax to be paid data " 324 " i.e. for this Shown for showing " tax+" in the line number " 02 " of amount of tax to be paid data as mark.

In addition, as shown in (A12) in Figure 12, if operating the registration data acknowledgement key ([▽] key 11d) (third time), Then display carries out described contain based on the data containing tax (data of tax computing 1) [tax+] accordingly registered with the line number " 02 " The amount of tax to be paid data " 24 " of result after tax computing (tax computing 1) and [tax of data containing tax accordingly called with line number " 03 " +] corresponding to symbol " tax+".In other words, carry out Figure 12 is shown for the numeric data " 324 " shown in (A11) in Figure 12 In (A11) shown in symbol data containing tax " tax+" processing after result be amount of tax to be paid data " 24 ", and the tax will be directed to Specified number is to be used to show that " tax+" in the line number " 03 " of the data containing the amount of tax to be paid to be used as symbol to be shown according to next processing of " 24 " Show.

Further, as shown in (A13) in Figure 12, if operating the registration data acknowledgement key ([▽] key 11d) the (the 4th It is secondary), then the data containing tax [tax+] that display is based on the line number " 03 " is accordingly registered carry out the computing containing tax, and (tax is transported Calculate) after result data containing the amount of tax to be paid " 324 " and with line number " 04 " accordingly call be free of tax data (tax computing 2 counts According to) symbol " tax-" corresponding to [tax -].In other words, for the numeric data " 24 " shown in (A12) in Figure 12 come show into Result after the processing of the data containing tax " tax+" of the symbol shown in (A12) in row Figure 12 is data containing the amount of tax to be paid " 324 ", and Next processing that this contains amount of tax to be paid data " 324 " will be directed to be used to show that " tax-" in the line number " 04 " without amount of tax to be paid data is made Shown for symbol.

Thus, even in carrying out a series of fortune after tax computing by the computing containing tax (or without tax computing) After the part in that counts is modified, by repeating the registration data acknowledgement key ([▽] key 11d), it can still hold Change places and confirm the revised data containing the amount of tax to be paid, amount of tax to be paid data and without amount of tax to be paid data.

In addition, in the step S44, operating the registration data acknowledgement key ([△] key 11e) and be set as confirming In the case of (retrieval) pattern, in a series of fortune that each line number with the operational data memory 22d is registered in association Calculate in operation data, call and show the arithmetic operation data (step S45) associated with the line number at end.

In addition, under described confirmation (retrieval) pattern, the situation of the registration data acknowledgement key ([△] key 11e) is being operated Under (step S46 (YES)), call associated with the previous line number of current line number and be registered in the operational data memory 22d Arithmetic operation data, show the result data or symbol (step S47, S48) of the tax computing based on the arithmetic operation data.

Also, as shown in (A14) in Figure 12, when (containing tax with the arithmetic operation data of the line number " 03 " having shown Data (data of tax computing 1) [tax+]) in the state of corresponding data containing the amount of tax to be paid (result data of tax computing 1) " 324 ", operation During [the reprinting] (registration data printing) key 11g (step S56 (YES)), the registration data printing treatment shown in Figure 10 is performed (step SP).

That is, when starting the registration data printing treatment, as shown in (B2) in Figure 12, by the Printing Department 13 to note [CA] that the P printings of record paper represent to reprint under pattern (all removes) the registration data printing beginning label of the situation of printing " 0 " (step P1).

Also, the current line number data of the line number memory 22e are set to " 01 " (step P2), judge to work as with described Preceding line number " 01 " is associated and is registered in whether the arithmetic operation data of the operational data memory 22d are to include numbered According to and operational data or arithmetic operation data (step P3) containing tax (or without tax) data.

Herein, it is judged as associated with current line number " 01 " and is registered in (reference picture in the operational data memory 22d (B) in 4) arithmetic operation data be to include the computing of numeric data " 300 " and data containing tax (data of tax computing 1) [tax+] Operation data (step P3 (YES)).

Then, be and then printed on the recording sheet P registration data printing beginning label " 0 ", as the tax operational data corresponding with the numeric data " 300 " and data containing tax [tax+], by the print Brush portion 13 prints the numeric data (being free of amount of tax to be paid data) " 300 " on recording sheet P and without amount of tax to be paid mark "-T ", tax rate number According to " 8 " and tax rate mark " %T ", amount of tax to be paid data " 24 " and amount of tax to be paid mark " T ", data containing the amount of tax to be paid (result data of tax computing 1) " 324 " and mark "+T " (step P4) containing the amount of tax to be paid.

Hereafter, judge to whether there is and next line number phase in the operational data memory 22d ((B) in reference picture 4) The arithmetic operation data (step P8) of association.Herein, it is judged as the arithmetic operation data associated with next line number " 02 " being present (data containing tax [tax+]) (step P8 (YES)), the current line number " 01 " of the line number memory 22e by (+1) and enter " 02 " (step P9).

Then, it is judged as associated with current line number " 02 " and is registered in the operational data memory 22d (reference pictures 4 In (B)) in arithmetic operation data be data containing tax (data of tax computing 1) [tax+], and neither including numeric data and fortune The arithmetic operation data of operator data, nor the arithmetic operation data including numeric data and containing tax (or without tax) data (step P3 (no)).Further, since in the arithmetic operation data associated with line number " 01 " before and and current line number There are data containing tax (data of tax computing 1) [tax+] in the arithmetic operation data of " 02 " association, therefore be judged as continuous tax computing Data (step P5 (YES)).In this case, (suppress to print) (step P6) without the printing to the recording sheet P.

Hereafter, as described above, (the step P8 in the case that current line number " 02 " is updated to " 03 " → " 04 " (YES), P9), as described above, it is continuous tax operational data (step to be judged as the arithmetic operation data associated with each line number Rapid P3 (no), P5 (YES)), therefore (suppress to print) (step P6) without the printing to the recording sheet P.

Thus, even in a series of computing after carrying out tax computing by the computing containing tax (or without tax computing) After a part in data is modified, by [reprinting] (registration data printing) key 11g described in operation, still can easily it exist Recording sheet P, which prints, corresponding with the result data of the revised computing containing tax is free of amount of tax to be paid data (- T), tax rate data (%T), amount of tax to be paid data (T) and data containing the amount of tax to be paid (+T).

Now, due to the recording sheet P beginning printing registration data printing beginning label " 0 ", therefore user can clearly distinguish the operation phase with [CA] the key 11h in the state of the printing model (ON) Corresponding generally printing (generally printing beginning label " 0 "), and confirm it is the operation phase with [reprinting] the key 11g The printing of corresponding revised registration data.

In addition, it is being judged as computing behaviour that is associated with current line number and being registered in the operational data memory 22d Make data neither arithmetic operation data (step P3 including numeric data and operational data or containing tax (or without tax) data (no)), nor in the case of continuous tax operational data (step P5 (no)), printing is stepped in association with the current line number The arithmetic operation data (step P7) of note.

In with reference to described Figure 12 come the second embodiment that illustrates, on for example in input commodity price (being free of the amount of tax to be paid) I.e. after numeric data " 200 ", [tax+] (computing containing tax is repeated：Tax computing 1) key 11b, and it is shown as data containing the amount of tax to be paid " 216 " → amount of tax to be paid data " 16 " → data containing the amount of tax to be paid " 216 ", then operate [tax -] and (be free of tax computing：Tax computing 2) key 11c is simultaneously Processing of the display without amount of tax to be paid data " 200 ", with according to step S10~S23 shown in described Fig. 6 and the step shown in above-mentioned Fig. 7 Rapid S41~S43 processing is illustrated.

On the other hand, on for example after input commodity price (containing the amount of tax to be paid) is numeric data, repeating [tax -] and (being free of tax Computing：Tax computing 2) key 11c, and be shown as without amount of tax to be paid data → amount of tax to be paid data → be free of amount of tax to be paid data, then operation [tax+] (computing containing tax：Tax computing 1) key 11b and the processing of the data containing the amount of tax to be paid is shown, only described " containing tax " [tax+] and " being free of tax " The processing of [tax -] is opposite and identical with above-mentioned processing, so as to step S27~S40 for being formed as shown in above-mentioned Fig. 7 and above-mentioned The processing of step S24~S26 shown in Fig. 6.
