Further, a recording medium according to claim 5 is recorded with a program for causing a computer to function as the printing control means of the tape printer according to any one of claims 1 to 3 and readable by the computer. Features.

In the tape printer according to claim 1, the tax rate of the consumption tax is stored , and this is stored in advance when the tax-excluded amount without the consumption tax is calculated from the tax-included amount input by the amount input means . The tax-excluded amount is calculated based on the tax rate. If there is no surplus in this tax-excluded amount, that is, if there is no fraction less than one currency unit, this tax-excluded amount is displayed as the tax-excluded amount corresponding to the input tax-included amount, and the print start key By pressing, it is possible to easily obtain a label on which label data including the tax-excluded amount is printed.
On the other hand, if there is a surplus in the tax-excluded amount, the tax-excluded amount obtained by discarding the remainder is stored as the first candidate tax-excluded amount. Then, the first candidate tax-included amount is calculated from the first candidate tax-excluded amount according to any currently set calculation method of “rounded up”, “rounded off”, or “rounded down”. If the first candidate tax-included amount matches the input tax-included amount, the first candidate tax-excluded amount is displayed as the tax-excluded amount corresponding to the input tax-included amount, and the print start key is pressed. By doing this, it is possible to easily obtain a label on which label data including the first candidate tax-excluded amount is printed.
On the other hand, if the first candidate tax-included amount does not match the input tax-included amount, the amount obtained by adding one currency unit to the first candidate tax-excluded amount is stored as the second candidate tax-excluded amount. Then, the second candidate tax-included amount is calculated from this second candidate tax-excluded amount according to any currently set calculation method of “rounded up”, “rounded off”, or “rounded down”. If the second candidate tax-included amount matches the input tax-included amount, the second candidate tax-excluded amount is displayed as the tax-excluded amount corresponding to the input tax-included amount, and the print start key is pressed. Thus, a label on which label data including the second candidate tax-excluded amount is printed can be easily obtained.
On the other hand, if the second candidate tax-included amount does not match the input tax-included amount, the first candidate tax-included amount and the first candidate tax-excluded amount are made to correspond to each other, and the second candidate tax-included amount and the second candidate tax-included amount The withdrawal amount is displayed in parallel with the corresponding amount. Then, by selecting one of the first candidate tax-excluded amount or the second candidate tax-excluded amount displayed in parallel as print data, a label including the selected first candidate tax-excluded amount or second candidate tax-excluded amount Data is printed on tape.
As a result, the user calculates the tax-excluded amount excluding the consumption tax corresponding to the input tax-included amount simply by inputting the tax-included amount, and easily labels the label data including the tax-excluded amount printed. Thus, it is possible to improve the workability of creating a label on which a tax-excluded amount is printed. If the tax-excluded amount excluding consumption tax corresponding to the input tax-included amount cannot be calculated, two candidate tax-included amounts modified from the input tax-included amount and each candidate tax-excluded corresponding to each candidate tax-included amount Since the amount is displayed, the user can easily confirm the two candidate tax-included amounts corrected and the respective candidate tax-excluded amounts corresponding to the candidate tax-included amounts. In addition, when one candidate tax-excluded amount is selected from these two candidate tax-included amounts and each candidate tax-excluded amount corresponding to each candidate tax-included amount, label data including the candidate tax-excluded amount is printed. A label can be easily obtained, and the workability of creating a label on which a tax-excluding amount is printed can be further improved.

In the tape printer according to claim 2, if the second candidate tax-included amount does not match the input tax-included amount, an error display indicating that the tax-excluded amount that matches the input tax-included amount cannot be calculated. Displayed at the same time. As a result, the display of the two candidate tax-included amounts corrected for the input tax-included amount and each candidate tax-excluded amount corresponding to each candidate tax-included amount indicates the corrected candidate tax-included amount and the candidate tax-excluded amount. This can be intuitively recognized, and the workability of creating a label printed with a tax-excluded amount can be further improved.

Further, in the tape printing apparatus according to claim 3, when the predetermined rate is changed by the rate changing means, since the rate which is changed in place of the predetermined rate are stored, then enter a tax amount case, and the tax amount on the basis of the changed tax rate, each candidate tax amount, Ru each candidate tax amount is calculated.
Thus, the user, when the rate is changed, only by inputting the changed rate through the rate changing means, then, tax amount calculated on the basis of the changed tax rate, A label printed with label data including either the first candidate tax-excluded amount or the second candidate tax-excluded amount can be easily obtained, and the tax- excluded amount corresponding to the new tax rate is printed. The workability of label production can be further improved.

Further, the program according to claim 4, by the computer that reads the program, to function as a control means of the tape printing apparatus according to any one of claims 1 to 3, the user, the tax-inclusive amount just type, tax amount of consumption tax corresponding to tax amount and the input, first candidate tax amount, or label the label data including any of the second candidate tax amount is printed Can be easily obtained, and the workability of creating a label printed with a tax- free amount can be improved.

Furthermore, the recording medium according to claim 5 can be provided with a function for realizing the print control means of the tape printer according to any one of claims 1 to 3 as a program executed by a computer. In the case of such a program, for example, semiconductor memory, hard disk, floppy (registered trademark) disk, data card (IC card, magnetic card, etc.), optical disk (CD-ROM, DVD, etc.), magneto-optical disk (MD, etc.), It can be used by recording on a computer-readable recording medium such as a phase change disk, magnetic tape, etc., and loading and starting the computer if necessary.

Next, a schematic configuration when the tape cassette 21 is mounted in the cassette housing portion 8 of the tape printer 1 will be described with reference to FIG.
As shown in FIG. 2, the tape cassette 21 has a print-receiving tape 36 made of a transparent tape or the like, an ink ribbon 30 for printing on the print-receiving tape 36, and a back-side printing on the print-receiving tape 36 on which printing has been performed. The double-sided adhesive tape 31 is wound around the tape spool 36A, the reel 30A, and the tape spool 31A, and is rotatably inserted into the cassette boss 36B, the reel boss 30B, and the cassette boss 31B standing on the bottom surface of the tape cassette. In addition, an ink ribbon take-up reel 30C for taking up the used ink ribbon 30 is provided.

  Then, the unused ink ribbon 30A wound around the reel 30A and pulled out from the reel 30A is overlapped with the print-receiving tape 36, enters the opening 32 together with the print-receiving tape 36, and the thermal head 9 and the platen roller 10. Pass between. Thereafter, the ink ribbon 30 is separated from the print-receiving tape 36, reaches the ink ribbon take-up reel 30 </ b> C rotated by the ribbon take-up shaft 15, and is taken up by the ink ribbon take-up reel 30 </ b> C.

  The double-sided pressure-sensitive adhesive tape 31 is wound and accommodated on a tape spool 31A with the release paper facing outside with the release paper superimposed on one side. The double-sided adhesive tape 31 pulled out from the tape spool 31A passes between the tape drive roller 33 and the tape feeding roller 11, and the adhesive surface on the side where the release paper is not superimposed is pasted on the print-receiving tape 36. Worn.

  Thus, the print-receiving tape 36 wound around the tape spool 36A and pulled out from the tape spool 36A passes through the opening 32 into which the thermal head 9 of the tape cassette 21 is inserted. Thereafter, the print-receiving tape 36 to which the double-sided adhesive tape 31 is bonded is rotatably provided at one side lower part (lower left side part in FIG. 2) of the tape cassette 21 and is rotated by the drive of the tape feed motor 52.

As shown in FIG. 6, first, in S21, the CPU 41 reads the tax rate stored as the consumption tax rate currently set in the RAM 45, displays the tax rate on the liquid crystal display 7, and displays this tax rate on the consumption tax. The liquid crystal display 7 displays a message asking whether to change the tax rate. When a new tax rate is input from the keyboard 6, the new tax rate is displayed on the liquid crystal display 7, and the new tax rate is stored in the RAM 45 as the currently set consumption tax rate.
Subsequently, in S22, the CPU 41 determines whether or not the tax rate displayed on the liquid crystal display 7 is determined as the tax rate of the display consumption tax, that is, determines whether or not the return key 4 is pressed within a predetermined time. Execute the judgment process. If the return key 4 has not been pressed within the predetermined time (S22: NO), the process of S21 is executed again.

  For example, as shown in FIG. 7A, the CPU 41 reads the tax rate stored in the tax rate storage area 44A, displays “currently set tax rate 5%” on the liquid crystal display 7, and displays “OK” below the tax rate. ? "Is displayed. When a new tax rate (for example, a numerical value such as “7” or “10” or “7%” or “10%”) is input, the input tax rate is displayed on the liquid crystal display 7. Is displayed instead of “5%” (for example, “7%”, “10%”, etc. is displayed), and “OK?” Is displayed below it, and this new tax rate is currently set. It is stored in the RAM 45 as the consumption tax rate.

On the other hand, when the return key 4 is pressed within a predetermined time (S22: YES), in 23, the CPU 41 again sets the tax rate displayed on the liquid crystal display 7 as the tax rate of the currently set consumption tax. The tax rate storage area 44A of the flash memory 44 stores the consumption tax rate.
Thereafter, the CPU 41 inputs a tax-excluded price from the ROM 43 and calculates a tax-inclusive price “tax-excluded → tax-inclusive” calculation mode, and calculates a tax-excluded price by inputting the tax-inclusive price. The mode is read out, each calculation mode is displayed on the liquid crystal display 7, and the currently set calculation mode is notified. At the time of activation, the calculation mode of “tax excluded → tax included” is stored in the RAM 45 as the setting calculation mode.
When the set calculation mode displayed on the liquid crystal display 7 is changed to another calculation mode with the cursor key 5, the changed calculation mode is changed to the currently set setting calculation mode. Notify that it has been done.

For example, as shown in FIG. 7B, the CPU 41 displays “current calculation mode” on the top of the liquid crystal display 7, displays “tax excluded → tax included” on the middle, and “tax included → tax included” on the bottom. "Unplugged" is displayed. In addition, an underline is displayed in the middle “tax excluded → tax included” and a black circle 61 is displayed at the right end to indicate that the currently set calculation mode is “tax excluded → tax included”. Notify. The black circle 61 is moved up and down by the cursor key 5.
If the black circle 61 is moved to the lower “tax included → tax excluded” by the cursor key 5, the black circle 61 is displayed at the right end of the lower “tax included → tax excluded” and is currently set. That the current calculation mode is changed to the calculation mode of “tax-included → tax-excluded”.

Subsequently, in S24, the CPU 41 determines whether or not the currently set calculation mode displayed on the liquid crystal display 7 has been changed, that is, whether or not the calculation mode has been changed to a calculation mode of “tax included → tax excluded”. Execute the process. In other words, the CPU 41 changes to the calculation mode of “tax-included → tax-excluded” by the cursor key 5 and executes a determination process for determining whether the return key 4 is pressed.
Then, when the cursor key 5 does not change the calculation mode to “tax-included → tax-excluded”, that is, when the return key 4 is pressed with the calculation mode “tax excluded → tax-included” set (S24: NO) In S25, the CPU 41 stores the calculation mode of “tax excluded → tax included” in the RAM 45 as the current setting calculation mode, and then executes a sub-process of “tax excluded → tax included processing” described later, and then returns to the main flowchart. .
On the other hand, when the cursor key 5 is used to change the calculation mode to “tax-included → tax-excluded” (S24: YES), in S26, the CPU 41 sets the calculation mode “tax-included → tax excluded” as the current set calculation mode. After storing in the RAM 45, after executing a sub-process of “tax-included → tax-excluded process” described later, the process returns to the main flowchart.

For example, as shown in FIG. 7B, when the return key 4 is pressed while the black circle 61 is displayed at the right end of “tax excluded → tax included” in the middle of the liquid crystal display 7 (S24). : NO), the CPU 41 stores the calculation mode of “tax excluded → tax included” in the RAM 45 as the setting calculation mode, and then executes a sub-process of “tax excluded → tax included processing” described later, and then returns to the main flowchart.
On the other hand, when the return key 4 is pressed in a state where the black circle 61 has been moved toward the “tax-included → tax-excluded” portion of the lower part of the liquid crystal display 7 by the cursor key 5 (S24: YES), the CPU 41 After this change, the calculation mode of “including tax → excluding tax” is stored in the RAM 45 as a new setting calculation mode, and after executing a sub process of “tax included → excluding tax” described later, the process returns to the main flowchart.

Next, the sub-processing of “tax excluded → tax included processing” executed in S25 will be described with reference to FIGS.
As shown in FIG. 8, in S <b> 31, the CPU 41 displays on the liquid crystal display 7 the request for inputting the tax-excluded price and displays the amount of money input via the keyboard 6 on the liquid crystal display 7.
For example, as shown in FIG. 9A, the CPU 41 displays “<Amount Input>” on the upper part of the liquid crystal display 7 and “Tax Excluded (Yen):” on the middle part. Indicates that input is requested. When “198” is input as the tax-excluded price, the tax-excluded price “198” input is displayed at the right end of the middle row.

In S <b> 32, when the return key 4 is pressed, the CPU 41 stores the input tax-excluded price in the RAM 45 as “tax-excluded price”. Further, the CPU 41 sequentially reads the round-down calculation method, the round-off calculation method, and the round-up calculation method from the calculation method storage area 43 </ b> C of the ROM 44 and stores each calculation method in the RAM 45.
In S <b> 33, the CPU 41 reads the tax rate of the consumption tax from the tax rate storage area 44 </ b> A of the flash memory 44 and stores it as the tax rate of the consumption tax currently set in the RAM 45.
Subsequently, in S34, the CPU 41 calculates a tax-inclusive price calculated by each calculation method from the inputted tax-excluded price, stores it as each “tax-inclusive price” in the RAM 45, and also calculates the tax-inclusive price calculated by each calculation method. Displayed on the liquid crystal display 7. Further, the CPU 41 reads the calculation method stored in the selection calculation method storage area 44B of the flash memory 44 and displays on the liquid crystal display 7 that the calculation method is currently set as a calculation condition for calculating the tax-inclusive price.
When the calculation method set as the calculation condition for calculating the tax-inclusive price displayed on the liquid crystal display 7 is changed to another calculation method by the cursor key 5, the changed calculation method is set at present. Notify that it has been changed as a calculation condition to calculate the price including tax.

  Subsequently, in S35, when the return key 4 is pressed, the CPU 41 re-executes the calculation method in which the fact that it is currently set as the calculation condition for calculating the tax-inclusive price is displayed on the liquid crystal display 7 again. 44 selection calculation method storage area 44B. In S36, the CPU 41 reads from the RAM 45 the “tax-included price” corresponding to the tax-included price calculated by the calculation method stored in the selection calculation method storage area 44B, and prints it on the print-receiving tape 36 in the edit input area 45B. After storing as “tax-included price”, the sub-process is terminated and the process returns to the consumption tax process.

  For example, as shown in FIG. 9B, the CPU 41 displays “rounded down:” representing the tax-inclusive price calculated by the rounded down calculation method on the upper part of the liquid crystal display 7 and corresponds to the input amount “198 yen”. “207 yen” which is the tax-inclusive price calculated by the round-down calculation method is displayed. In addition, the CPU 41 displays “rounding:” representing the tax-inclusive price calculated by the rounding calculation method in the middle of the liquid crystal display 7 and the tax-inclusive price calculated by the rounding-off calculation method for the input amount “198 yen”. A certain “208 yen” is displayed. Further, the CPU 41 displays “Round-up:” representing the tax-inclusive price calculated by the round-up calculation method on the lower part of the liquid crystal display 7 and also includes the tax-inclusive price calculated by the round-up calculation method for the input amount “198 yen”. A certain “208 yen” is displayed. Further, when the calculation method read from the selection calculation method storage area 44B of the flash memory 44 is the “cut-off calculation method”, the CPU 41 underlines “cut-off: 207 yen” displayed on the upper stage of the liquid crystal display 7. A line is displayed, and a black circle 62 is displayed at the right end to indicate that the round-down calculation method is currently set as a calculation condition for calculating a tax-inclusive price. The black circle 61 is moved up and down by the cursor key 5.

Then, as shown in FIG. 9C, when the black circle 62 is moved by the cursor key 5 toward the middle “rounding off: 208 yen”, the CPU 41 underlines the “rounding off: 208 yen”. A line is displayed to indicate that the rounding calculation method has been selected as the calculation condition for calculating the price including tax.
Subsequently, when the return key 4 is pressed, a rounding calculation method corresponding to “rounding: 208 yen” marked with the black circle 62 is stored in the selection calculation method storage area 44B of the flash memory 44, and After storing this tax-included price “208 yen” as “tax-included price” to be printed on the print-receiving tape 36 in the edit input area 45B, the sub-process is terminated, and the process returns to the various-tax process.

Next, the sub-process of “tax-included → tax-excluded process” executed in S26 will be described with reference to FIGS.
As shown in FIG. 10, in S <b> 41, the CPU 41 displays on the liquid crystal display 7 that the liquid crystal display 7 requests to input the tax-inclusive price, and displays the amount input via the keyboard 6.
For example, as shown in FIG. 12A, the CPU 41 displays “<amount input>” in the upper part of the liquid crystal display 7 and “tax included (yen):” in the middle part, and inputs the price including tax. Display the request. When the amount “105 yen” is input, the CPU 41 displays “105” at the right end of the middle row.
Further, as shown in FIG. 13A, the CPU 41 displays “<amount input>” in the upper part of the liquid crystal display 7 and “tax included (yen):” in the middle part, and inputs the price including tax. Display the request. When the amount “115 yen” is input, the CPU 41 displays “115” at the right end of the middle row.

In S <b> 42, when the return key 4 is pressed, the CPU 41 stores the input amount in the RAM 45 as “tax-included price”. Further, the tax rate is read from the tax rate storage area 44A of the flash memory 44, and the tax rate is stored in the RAM 45 as the currently set consumption tax rate. Further, the calculation method stored in the selection calculation method storage area 44B of the flash memory 44 is read, and the calculation method is stored in the RAM 45 as the currently set calculation condition.
Subsequently, in S43, the CPU 41 calculates a “tax-excluded price” based on the inputted “tax-included price” stored in the RAM 45 and the tax rate of the consumption tax, and again from the calculated “tax-excluded price”. The “tax-included price” is calculated based on the tax rate of the consumption tax stored in the RAM 45, and the calculated “tax-included price” is checked whether or not the input “tax-included price” matches. Execute sub-processing of “Price calculation / verification from calculation result”.

Here, the sub-process of “calculation without tax calculation / verification from calculation result” will be described with reference to FIG.
As shown in FIG. 11, in S51, the CPU 41 adds “1” to the numerical value of the tax rate based on the inputted “tax-included price” stored in the RAM 45 and the tax rate of the consumption tax (for example, consumption When the tax is 5%, the value is 1 + 0.05 = 1.05.) The “tax-excluded price” is calculated by dividing this “tax-included price”, and the “tax-excluded price” ( Stored as the first tax-excluded amount.
Subsequently, in S52, the CPU 41 reads the “tax-excluded price” (first tax-excluded price) from the RAM 45 again, and whether there is a remainder, that is, whether there is a fraction less than one yen (unit currency). A determination process is performed to determine whether or not.
When the “tax-excluded price” (first tax-excluded price) is not excessive, that is, when there is no fraction less than one yen (unit currency) (S52: NO), in S53, the CPU 41 The “tax-excluded price” (first tax-excluded price) is fixed as the “tax-excluded price” corresponding to the inputted “tax-included price” and stored in the RAM 45 as the confirmed “tax-excluded price”. Further, the CPU 41 reads the tax-excluded price flag from the RAM 45, turns on the tax-excluded price flag, stores it again in the RAM 45, ends the sub-process, and enters the sub-process of “tax-included → tax-excluded mode process”. Return.

On the other hand, if the “tax-excluded price” (first tax-excluded price) has a remainder, that is, there is a fraction less than 1 yen (unit currency) (S52: YES), in S54, the CPU 41 The amount less than 1 yen (unit currency) of the “tax-excluded price” (first tax-excluded price) is stored in the RAM 45 as “tax-excluded price candidate 1” (second tax-excluded price).
In S55, the CPU 41 reads the currently set tax rate of the consumption tax from the RAM 45, and calculates “tax-included price” from “tax-excluded price candidate 1” (second tax-excluded amount).
Subsequently, in S56, the CPU 41 reads out the calculation method as the currently set calculation condition from the RAM 45, processes the calculated “tax-included price” of less than 1 yen (unit currency), and again executes this calculation. The calculated “tax-included price” is stored in the RAM 45 as the calculated “tax-included price” (first tax-included amount). Therefore, if the currently set calculation method is the round-down calculation method, the amount less than 1 yen (unit currency) of the “tax-included price” is rounded down to the calculated “tax-included price” (No. 1 amount including tax) is stored in the RAM 45. In addition, when the calculation method as the currently set calculation condition is the rounding off calculation method, the amount rounded off to the nearest less than 1 yen (unit currency) of the “tax included price” is the calculated “tax included price” (No. 1 amount including tax) is stored in the RAM 45. Furthermore, when the calculation method as the currently set calculation condition is a round-up calculation method, the amount obtained by rounding up the fraction less than 1 yen (unit currency) of the “tax-included price” is the calculated “tax-included price” (No. 1 amount including tax) is stored in the RAM 45.

  For example, when the input “tax-included price” is “115 yen” and the consumption tax is 5%, “109 yen” is stored in the RAM 45 as “tax-excluded price candidate 1” (second tax-excluded amount). The Further, when the calculation method as the currently set calculation condition is a rounding calculation method, “114 yen” is stored in the RAM 45 as the “tax-included price” (first tax-included amount) calculated.

In S <b> 57, the CPU 41 reads the “tax-inclusive price” (first tax-inclusive price) calculated from the RAM 45, and executes a determination process for determining whether or not the input “tax-inclusive price” matches.
When the calculated “tax-included price” (first tax-included price) matches the inputted “tax-included price” (S57: YES), the CPU 41 reads “candidate price candidate 1” from the RAM 45 in S53. "(Tax-excluded amount)" is read, and "Tax-excluded price candidate 1" (Second tax-excluded amount) is confirmed as the "Tax-excluded price" corresponding to the entered "Tax-inclusive price" It is stored in the RAM 45 as a “price”. Further, the CPU 41 reads the tax-excluded price flag from the RAM 45, turns on the tax-excluded price flag, stores it again in the RAM 45, ends the sub-process, and enters the sub-process of “tax-included → tax-excluded mode process”. Return.

On the other hand, if the calculated “tax-included price” (first tax-included price) does not match the inputted “tax-included price” in S57 (S57: NO), the CPU 41 reads “excluding tax” from the RAM 45 in S58. “Price candidate 1” (second tax-excluded amount) is read out, and the amount obtained by adding 1 yen (unit currency) to the “tax-excluded price candidate 1” (second tax-excluded amount) is added to “tax-excluded price candidate 2” (third It is stored in the RAM 45 as a tax-excluded amount.
In S <b> 59, the CPU 41 reads the currently set consumption tax rate from the RAM 45, and calculates “tax-included price” from “tax-excluded price candidate 2” (third tax-excluded amount).
Subsequently, in S60, the CPU 41 reads out the calculation method as the currently set calculation condition from the RAM 45, processes the calculated “tax-included price” of less than 1 yen (unit currency), and again executes this calculation. The calculated “tax-included price” is stored in the RAM 45 as the calculated “tax-included amount” (second tax-included amount). Therefore, if the currently set calculation method is the round-down calculation method, the amount less than 1 yen (unit currency) of the “tax-included price” is rounded down to the calculated “tax-included price” (No. 2) (including tax). In addition, when the calculation method as the currently set calculation condition is the rounding off calculation method, the amount rounded off to the nearest less than 1 yen (unit currency) of the “tax included price” is the calculated “tax included price” (No. 2) (including tax). Furthermore, when the calculation method as the currently set calculation condition is a round-up calculation method, the amount obtained by rounding up the fraction less than 1 yen (unit currency) of the “tax-included price” is the calculated “tax-included price” (No. 2) (including tax).

  For example, if the input “tax-included price” is “115 yen” and the consumption tax is 5%, “110 yen” is stored in the RAM 45 as “tax-excluded price candidate 2” (third tax-excluded amount). The In addition, when the calculation method as the currently set calculation condition is a rounding calculation method, “116 yen” is stored in the RAM 45 as the “tax-included price” (second tax-included amount) calculated.

In S <b> 61, the CPU 41 reads the “tax-included price” (second tax-included price) calculated from the RAM 45 and executes a determination process for determining whether or not the input “tax-included price” matches.
If the calculated “tax-included price” (second tax-included price) matches the input “tax-included price” (S61: YES), in S53, the CPU 41 reads the “tax-excluded price candidate 2” from the RAM 45. "(Tax-excluded amount)", and "Tax-excluded price candidate 2" (Third tax-excluded amount) is confirmed as the "Tax-free price" corresponding to the entered "Tax-inclusive price" It is stored in the RAM 45 as a “price”. Further, the CPU 41 reads the tax-excluded price flag from the RAM 45, turns on the tax-excluded price flag, stores it again in the RAM 45, ends the sub-process, and enters the sub-process of “tax-included → tax-excluded mode process”. Return.

  On the other hand, when the calculated “tax-included price” (second tax-included price) does not match the input “tax-included price” in S61 (S61: NO), in S62, the CPU 41 reads “ “Price candidate 1” (second tax-excluded price) and “tax-excluded price candidate 2” (third tax-excluded price) are read out and stored in the RAM 45 as a selection confirmation “tax-excluded price”. Further, the CPU 41 reads the tax-excluded price flag from the RAM 45, turns off the tax-excluded price flag, stores it again in the RAM 45, terminates the sub-process, and enters the sub-process of “tax-included → tax-excluded mode process”. Return.

Subsequently, as shown in FIG. 10, in S44, the CPU 41 determines whether or not the verification results match in the process of S43, that is, whether the tax-excluded price flag read from the RAM 45 is ON or OFF. Execute.
If it is determined that the verification results match, that is, if the tax-excluded price flag read from the RAM 45 is ON, in S45, the CPU 41 confirms the “tax-included price” input from the RAM 45 and the determined “tax-excluded price”. ”And read the“ tax-included price ”and the confirmed“ tax-excluded price ”on the liquid crystal display 7. In addition, the liquid crystal display 7 displays a message asking whether or not to print the “tax-included price” and the confirmed “tax-excluded price” on the tape to be printed 36.

  For example, as shown in FIG. 12B, the CPU 41 reads the “tax-included price” (105 yen) and the confirmed “tax-excluded price” (100 yen) input from the RAM 45, and reads “105 yen on the liquid crystal display 7. : 100 yen without tax ". In addition, an underline is displayed at “105 yen: 100 yen excluding tax”. Further, “OK?” Is displayed below the screen, and a message is displayed asking whether or not to print the “tax-included price” and the finalized “tax-excluded price” on the print-receiving tape 36.

In S46, the CPU 41 determines whether or not it is decided to print the “tax-included price” and the confirmed “tax-excluded price” displayed on the liquid crystal display 7 on the print-receiving tape 36, that is, the return key 4 is pressed. A determination process for determining whether or not the process has been performed is executed. If the return key 4 has not been pressed within the predetermined time (S46: NO), the process of S41 is executed again.
On the other hand, if the return key 4 is pressed within a predetermined time (S46: YES), the CPU 41 reads the "tax-included price" and the confirmed "tax-excluded price" from the RAM 45 at 47, and prints the tape to be printed. After the “tax-included price” and “tax-excluded price” to be printed on 36 are stored in the edit input area 45B, the sub-process is terminated and the process returns to the consumption tax process.

  On the other hand, if it is determined in S44 that the verification results do not match, that is, if the tax-excluded price flag read from the RAM 45 is OFF, in S48, the CPU 41 selects the “tax-included price” input to the liquid crystal display 7. Display that “Tax-excluded price” could not be calculated. At the same time, the CPU 41 calculates from the RAM 45 the “tax-excluded price candidate 1” (second tax-excluded price) and the calculated “tax-included price” (first tax-excluded price) corresponding to the “tax-excluded price candidate 1” (second tax-excluded price). The tax-excluded price) is read out, and the “tax-excluded price candidate 1” (second tax-excluded price) and the “tax-included price” (first tax-included price) are displayed on the liquid crystal display 7. At the same time, the CPU 41 calculates from the RAM 45 the “tax-excluded price candidate 2” (third tax-excluded amount) and the “tax-excluded price” (second tax-excluded) calculated corresponding to the “tax-excluded price candidate 2” (third tax-excluded amount). The tax-excluded price) is read out, and the “tax-excluded price candidate 2” (third tax-excluded price) and the “tax-included price” (second tax-included price) are displayed on the liquid crystal display 7.

  For example, as shown in FIG. 13 (B), the CPU 41 indicates that the “tax-excluded price” for the inputted “tax-included price” cannot be calculated in the upper part of the liquid crystal display 7 “115 yen including tax is an error”. Is displayed. Further, when the rounding off calculation method is currently set as the calculation condition and the consumption tax is 5%, the CPU 41 calculates the “tax-included price” (the amount including the first tax) calculated from “115 yen” of the input “tax-included price”. ) “114 yen” and “109 yen”, which is “tax-excluded price candidate 1” (second tax-excluded amount), are read from the RAM 45, and “114 yen: 109 yen without tax” is displayed in the middle of the liquid crystal display 7. Is displayed. Further, when the rounding off calculation method is currently set as the calculation condition and the consumption tax is 5%, the CPU 41 calculates the “tax-included price” (the amount including the second tax) calculated from “115 yen” of the input “tax-included price”. ) “116 yen” and “110 yen without tax” (third tax-excluded price) are read from the RAM 45, and “116 yen: 110 yen without tax” are displayed in the middle of the liquid crystal display 7. Is displayed.

In S49, the CPU 41 displays the “tax-excluded price candidate 1” (second tax-excluded price) and “tax-included price” (first tax-included price) displayed on the liquid crystal display 7 on the print-receiving tape 36. It is displayed that “Price without tax” and “Price including tax” to be printed are currently set.
When the “tax-excluded price candidate 2” (third tax-excluded price) and “tax-included price” (second tax-included price) displayed on the liquid crystal display 7 are selected by the cursor key 5, “Tax-excluded price candidate 2” (third tax-excluded price) and “tax-included price” (second tax-included price) are currently set as “tax-excluded price” and “tax-included price” printed on the print-receiving tape 36. Is displayed.

For example, as shown in FIG. 13B, the CPU 41 displays a black circle 63 on the right end of “114 yen: 109 yen excluding tax” on the liquid crystal display 7, “114 yen” as the price including tax, "109 Yen" is displayed as "Tax-excluded price" and "Tax-included price" that are currently set on the tape 36 to be printed. The black circle 63 is moved up and down by the cursor key 5.
When the black circle 63 is moved downward by the cursor key 5, the black circle 63 is displayed at the right end of “116 yen: 110 yen excluding tax” on the liquid crystal display 7, and the price including tax is “116 yen. “Tax-excluded price” and “Tax-inclusive price” that are currently set as “tax-excluded price” and “tax-included price” printed on the print-receiving tape 36 are displayed.

Subsequently, in S46, the CPU 41 determines whether or not it is decided to print the “tax-excluded price” and the “tax-included price” on which the black circle mark 63 displayed on the liquid crystal display 7 is printed on the print-receiving tape 36. That is, a determination process for determining whether or not the return key 4 has been pressed is executed. If the return key 4 has not been pressed within the predetermined time (S46: NO), the process of S41 is executed again.
On the other hand, when the return key 4 is pressed within a predetermined time (S46: YES), in 47, the CPU 41 prints the "tax-excluded price" and the "tax-included price" on which this black circle 63 is displayed. After the “tax-included price” and “tax-excluded price” to be printed on the tape 36 are stored in the edit input area 45B, the sub-process is terminated and the process returns to the consumption tax process.

Next, the “printing process” sub-process executed in S7 will be described with reference to FIGS.
As shown in FIG. 7, first, in S71, the CPU 41 executes a process for determining a print mode. In the process of determining the print mode, when the print mode selection key 13C is not pressed, the initial setting mode stored in the ROM 43 is read and stored in the RAM 45 as the print mode.
When the print mode selection key 13C is pressed, the CPU 41 first displays a layout selection display for determining the layout of “tax-included price” and “tax-excluded price” printed on the print-receiving tape 36. Displayed on the display 7.

For example, as shown in FIGS. 15A to 15D, when the tape width of the tape cassette 21 stored in the cassette storage unit 8 is 6 mm to 9 mm, “1” every time the cursor key 5 is pressed. "Row A"layout->"1 row B"layout->"1 row C"layout->"1 row D"layout->"1 row A"layout->"1 row B"layout-> Each layout for printing “tax-included price” and “tax-excluded price” in one line on the print-receiving tape 36 is sequentially displayed on the liquid crystal display 7.
Further, as shown in FIGS. 15A to 15F, when the tape width of the tape cassette 21 stored in the cassette storage unit 8 is 12 mm to 18 mm, every time the cursor key 5 is pressed, “1 "Row A"layout->"1 row B"layout->"1 row C"layout->"1 row D"layout->"2 row A"layout->"2 row B"layout->"1 row A" Layout of “1 line B” →... And each layout for printing “tax-inclusive price” and “tax-excluded price” in one line on the print-receiving tape 36 is sequentially displayed on the liquid crystal display 7.

When the return key 4 is pressed, the layout displayed on the liquid crystal display 7 is stored in the RAM 45 as a layout for printing “tax-included price” and “tax-excluded price” on the print-receiving tape 36.
Subsequently, the CPU 41 displays a display screen for selecting “typeface” and “with / without frame” on the liquid crystal display 7.

For example, as shown in FIG. 16A, a “typeface” selection field is displayed in the upper part of the liquid crystal display 7, and a “with / without frame” selection field is displayed below. Then, a state in which the typeface type is selected is displayed by enclosing the typeface name in a frame. In this case, each time the cursor key 5 is pressed, the typeface name is changed. When the return key 4 is pressed, the typeface name typeface in the frame is printed as "tax-included price" and "tax-excluded price". It is stored in the RAM 45 as the type of font to be printed on the tape 36.
Further, as shown in FIG. 16B, when “Gothic” is selected as “Typeface”, the CPU 41 displays “Yes” or “Yes” in the “Waku” column every time the cursor key 5 is pressed. When “None” is displayed alternately in a frame and “Yes” is displayed, when the return key 4 is pressed, “Tax included price” and “Tax excluded price” are surrounded by a frame. A print style to be printed on the print tape 36 is stored in the RAM 45. In addition, when “None” is displayed, when the return key 4 is pressed, a printing style for printing “tax-included price” and “tax-excluded price” on the print-receiving tape 36 without a frame is stored in the RAM 45. To do.

  When the layout and print style for printing the “tax-included price” and the “tax-excluded price” on the print-receiving tape 36 are determined, the CPU 41 waits for the print key 3 to be pressed again in S72. (S72: NO). When the print key 3 is pressed (S72: YES), in S73, the CPU 41 reads the layout and print style to be printed stored in the RAM 45, and based on these, the “tax-included price” and the “tax-excluded price” are read out. ”And stored in the print buffer 45A, and sequentially printed on the print-receiving tape 36, and after creating the print tape 22 on which“ tax-included price ”and“ tax-excluded price ”are printed, the sub-process To return to the main flowchart.

  Here, FIG. 17 shows an example of printing on the printing tape 22 having a tape width of 18 mm when the “tax-included price” is “1,029 yen” and the “tax-excluded price” is “980 yen”. FIG. 17A shows an example of the print tape 22 printed when the layout is “one line A”, the “typeface” is “Gothic”, and the “frame” is “none”. FIG. 17B is an example of the print tape 22 printed when the layout is “one line B”, the “typeface” is “Gothic”, and the “frame” is “none”.

Therefore, in the tape printer 1 according to the present embodiment, when the user obtains the printing tape 22 on which the tax-inclusive price is printed, each calculation method for calculating the tax-inclusive price by simply inputting the tax-exclusive price and Since each corresponding tax-inclusive price is displayed in parallel on the liquid crystal display 7, the tax-inclusive price to be printed can be determined easily and quickly. In addition, the user can easily obtain a label on which label data including the selected tax-included price is printed by simply selecting a desired tax-included price from the respective tax-included prices displayed in parallel on the liquid crystal display 7. It is possible to improve the workability of creating a label printed with a price.
Also, if you do not change the calculation method for calculating the tax-inclusive price from the tax-excluded price (for example, rounding down), each time the tax-excluded price is entered, the tax-inclusive price displayed in parallel for each calculation method is used. Since the tax-inclusive price of the desired calculation method is selected, the user does not need to select the tax-inclusive price to be printed from a plurality of tax-inclusive prices displayed in parallel on the liquid crystal display 7, and the tax is included only by pressing the print key 3. The printing tape 22 on which the label data including the price is printed can be easily obtained, and the workability of creating the label on which the price including tax is printed can be further improved.

Further, when the tax rate of the consumption tax is changed, the user simply inputs the changed tax rate on the display screen (see FIG. 7A) on which the currently set tax rate is displayed. Thereafter, since the tax-inclusive price corresponding to the new tax rate is displayed in parallel on the liquid crystal display 7, the tax-inclusive price to be printed on the print-receiving tape 36 can be determined easily and quickly. Further, the user simply selects a desired tax-inclusive price from each tax-inclusive price corresponding to the new tax rate displayed in parallel on the liquid crystal display 7, and the printing tape 22 on which the label data including the selected tax-inclusive price is printed. It can be easily obtained, and it is possible to further improve the workability of creating a label on which a tax-included amount corresponding to a new tax rate is printed.
The calculation method selected when the tax-included price including consumption tax selected as the previous print data is calculated is stored in the selection calculation method storage area 44B, and the tax rate of the consumption tax is stored in the tax rate storage area 44A. When the tax-excluded price is calculated again by inputting the tax-inclusive price and the tax-excluded price corresponding to the tax-inclusive price is calculated, the tax-exclusive price (the first tax-excluded amount is calculated based on the pre-stored tax rate. ) Is calculated. If there is no surplus in the tax-excluded price (first tax-excluded price), that is, if there is no fraction less than 1 yen (currency unit), the tax-excluded price corresponding to the entered tax-inclusive price The calculated tax-excluded price (first tax-excluded amount) is displayed, and by pressing the print key 3, a label on which label data including the tax-excluded price (first tax-excluded amount) is printed can be easily obtained. it can.

On the other hand, if there is a surplus in the calculated tax-excluded price (first tax-excluded price), the tax-excluded price candidate 1 (second excl. The tax-inclusive price (first tax-inclusive amount) is calculated according to the calculation method stored in the selection calculation method storage area 44B. If the calculated tax-inclusive price (first tax-inclusive amount) matches the input tax-inclusive price, the tax-excluded price candidate 1 (second tax) is selected as the tax-excluded price corresponding to the input tax-inclusive price. When the print key 3 is pressed, a label printed with label data including the tax-excluded price candidate 1 (second tax-excluded amount) can be easily obtained.
On the other hand, if this calculated tax-inclusive price (first tax-inclusive amount) does not match the input tax-inclusive price, this tax-excluded price candidate 1 (second tax-excluded amount) is added 1 yen (in currency units). The tax-excluded price candidate 2 (third tax-excluded amount) and the tax-included price (second tax-included amount) according to the calculation method stored in the selection calculation method storage area 44B from the tax-excluded price candidate 2 (third tax-excluded amount) calculate. If the calculated tax-inclusive price (second tax-inclusive amount) matches the input tax-inclusive price, the tax-excluded price candidate 2 (third tax) is included as the tax-excluded price corresponding to the input tax-inclusive price. When the print key 3 is pressed, a label on which label data including the tax-excluded price candidate 2 (third tax-excluded amount) is printed can be easily obtained.
Therefore, the user enters the price including tax according to the calculation method corresponding to the calculation method selected when the tax-included amount including consumption tax selected as the previous print data is calculated by inputting the price including tax. The tax-excluded price corresponding to the consumption tax is calculated and the label data including the tax-excluded price can be easily obtained, improving the workability of creating the label with the tax-excluded price printed. Can be planned.

In addition, the tax-excluded amount without the consumption tax corresponding to the entered tax-inclusive price cannot be calculated according to the calculation method selected when calculating the tax-inclusive price including the consumption tax selected as the previous print data and the tax rate of the consumption tax. In this case, the tax-excluded price candidate 1 (second tax-excluded price) obtained by correcting the input tax-included price, the corresponding tax-included price (first tax-included price), and the tax-exclusive price candidate 2 (third tax-excluded price) ) And the corresponding tax-included price (second tax-included price) are displayed, the user can easily confirm a plurality of corrected tax-included prices and the tax-excluded price corresponding to each tax-included price. In addition, when a single tax-excluded price is selected from the corrected plural tax-included prices and the tax-excluded price corresponding to each tax-included price, the printing tape 22 on which the label data including the tax-excluded price is printed can be easily obtained. Thus, it is possible to further improve the workability of creating a label printed with a tax-excluded price.
Also, the tax-excluded price without the consumption tax corresponding to the entered tax-included price cannot be calculated according to the calculation method selected when calculating the tax-included price including the consumption tax selected as the previous print data and the tax rate of the consumption tax. In this case, since an error display indicating that a tax-excluded price that cannot match the entered tax-included price cannot be calculated is displayed at the same time, the user can modify multiple entered tax-included prices and each tax-included price. It is possible to intuitively recognize that the display of the tax-excluded price corresponding to indicates multiple correction candidates, and further improve the workability of creating a label with the tax-excluded price printed. it can.
Furthermore, when calculating the tax-included price from the entered tax-excluded price, a round-down calculation method that rounds off less than 1 yen (currency unit), a round-off calculation method that rounds off less than 1 yen (currency unit), and 1 yen ( Since a plurality of tax-inclusive prices are calculated and displayed in parallel on the liquid crystal display 7 in accordance with a round-up calculation method that rounds up less than a currency unit), the user can easily and easily select a desired tax-inclusive price from a plurality of tax-inclusive prices. .
