Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing apparatus with a currency calculation function for converting a predetermined amount input in a certain country into an amount in a currency of another country based on a currency exchange rate and printing the same. In particular, with a currency calculation function that can store the entered characters etc. in the storage means and convert the number in the text stored in the storage means as a predetermined amount in one country to the amount of currency in another country It relates to a printing device.

[0002]

2. Description of the Related Art Currency exchange rates (exchange rates) have conventionally been used.
Various printing devices have been proposed that convert a predetermined amount of money in a certain country into an amount of money in another country and print the same based on the above. For example, such a printing device is disclosed in Japanese Patent Application Laid-Open No. 51-86336. It is disclosed as a currency calculator. In the currency calculator described in the publication, the exchange rate (for example, 1 dollar = 295.28 yen) is set in advance using an amount button or the like with the operation switch on the operation panel set at the exchange rate entry position. It must be entered and memorized. Then, in a state where the user sets the operation switch to the operation use position, for example, after inputting the type of US dollar and further inputting the amount (for example, $ 265.12), the type of currency (yen) When the input, the subtotal button and the like are operated, the Japanese yen is 78284.63 yen (= $ 265.12 × 295.
28 yen).

[0003]

However, in the case of the currency calculator disclosed in the above publication, when the input amount of one country (US) is converted into the amount of currency of another country (Japan), the operation switch is operated in advance. It must be set to the usage position, and the amount entered before setting cannot be converted to the amount in the currency of another country. Therefore, even if you want to convert the entered value to the currency of another country before setting it to the operation use position, it cannot be converted, and you must set the operation switch to the operation use position again. Therefore, it was necessary to restart the numerical input and the like from the beginning, and the operability was not so good.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems. When converting to an amount of currency of another country, the operation switch can be set in advance without setting the operation switch to the operation use position. It is an object of the present invention to provide an excellent printing device with a currency calculation function that can convert a number stored in a storage unit into a currency amount of another country and print the converted amount.

[0005]

According to the present invention, there is provided a printing apparatus having a currency calculation function, comprising: input means for inputting text including characters, numerals, and the like; Text characters entered from,

When the operation member is operated, a conversion unit that converts the number stored in the storage unit into a currency amount of a certain country into a currency amount of another country, and an amount converted by the conversion unit. And printing means for printing characters and the like stored in the storage means.

In the present invention having the above-described structure, when the operating member is operated, text consisting of characters, numbers, and the like input through the input means is stored in the storage means, and the conversion means is stored in the storage means. Since the number is converted into a predetermined amount in a certain country and converted into an amount in a currency of another country, the printing unit can print a text including characters, numbers, and the like stored in the storage unit. As a result, if the user enters various texts including the input amount and later realizes that it was necessary to convert the input amount of one country in the text into the amount of the currency of another country. Even so, if the operating member is operated, the previously entered numerical value is converted into the amount of the currency of another country as the input amount of one country, so the input operation is less repeated and the operability is extremely good Becomes The operation member is preferably, for example, a currency calculation key on a keyboard, but is not necessarily limited to this mode.

According to a second aspect of the present invention, in the printing device with a currency calculation function according to the first aspect, the storage means includes a storage area for storing a text input from the input means, A work area for converting the numerical data and the like in the storage area into a currency amount of a certain country as a currency amount of a certain country, and obtaining a numeric data and the like from the storage area in the work area; Control means for converting the value into the amount of currency of the country and returning the value to the storage area.

[0008] As described above, the control means obtains numerical data and the like from the storage area for storing the text and converts the amount of currency of one country into the amount of currency of another country using the work area. Since the data is returned to the storage area after performing the operation, the storage area for storing the text contains data converted into the amount of the currency of another country instead of the inputted numerical data and the like. Can be printed, such as text consisting of characters, numbers, and the like stored in the storage area of the. In this case, for example, when the numerical data and the currency unit symbol are stored in the storage area, the mode of acquiring only the numerical data from the storage area is used. The acquisition mode may be adopted as needed.

According to a third aspect of the present invention, in the printing apparatus with the currency calculating function according to the first aspect, a price tag can be created. In a country or region where a plurality of currencies are distributed, it is desirable that the price tag indicating the price of a product or the like be displayed in the amount of a plurality of currencies. Can be created. Then, it is desirable that the price of a certain product is printed with the amount of currency of one country and the amount of currency of another country side by side, such as up and down or left and right, on the price tag.

Next, a description will be given of a thermal printing mechanism PM as printing means provided inside the rear of the main body frame 2 with reference to FIG. FIG. 2 shows a tape cassette 10.
FIG. 3 is an enlarged plan view showing a thermal printing mechanism PM excluding an upper case of a tape cassette 10. In FIG.
The tape cassette 10 is detachably attached to the thermal printing mechanism PM. In the tape cassette 10, a tape spool 12 around which a laminate tape 11 as a printing tape is wound, a ribbon spool 14 around which an ink ribbon 13 is wound, and an ink ribbon 13 pulled out from the ribbon spool 14 at the time of printing are wound. The take-up spool 15, the double-sided tape 16 having the same width as the laminate tape 11, and the double-sided tape spool 17 wound with the release paper outside, and the laminated tape 11 and the double-sided tape 16 after printing are pressed against each other. Roller 18 to join
Are rotatably provided.

A thermal head 19 is provided upright at a position where the laminating tape 11 and the ink ribbon 13 overlap each other.
The heating elements are arranged vertically. Further, a roller support 22 is rotatably arranged facing the thermal head 19, and a platen roller 20 and a feed roller 21 are rotatably supported on the roller support 22. Here, the platen roller 20 has a function of pressing the thermal head 19 in a state where the laminate tape 11 and the ink ribbon 13 are overlapped during printing, and the feed roller 21 performs the operation of the laminating tape 11 and the double-sided tape 16 after printing. Is pressed against the joining roller 18 so that the tape 23 with the character
While feeding the tape in the direction of arrow T.

When the tape 23 with the character is formed in the above-described configuration, the tape feed motor 45 (see FIG. 3) is driven in a predetermined rotation direction. Driven in the rotational direction. When each heating element in the thermal head 19 is selectively energized, the laminate tape 11
On the back side, characters, numbers, etc. are printed in a mirror image relationship by a plurality of dot rows, and further, the back side of the laminate tape 11 (characters, etc. are printed by cooperation of the joining roller 18 and the feed roller 21). ), The double-sided tape 16 is joined to form the tape 23 with a letter, and the tape 23 with the letter is fed in the direction of the arrow T. Since the character-attached tape 23 thus created is sent out of the main body frame 2, the printing device 1 with a currency calculation function can create the character-attached tape 23 as a price tag, for example.

Next, a control system of the printer 1 with the currency calculation function will be described with reference to FIG. FIG. 3 is a control block diagram of the printing device 1 with a currency calculation function according to the present embodiment, which is configured with the control device C as a core. The control device C as control means includes a CPU 32, a CGROM 3
3, a ROM 34, a RAM 35, etc., which are connected to each other via a bus 31 and also to an input / output interface 30.

The ROM 34 stores various programs. The ROM 34 stores a main processing program, a printing processing program, a character rearranging processing program, a sequential printing processing program, and a printing apparatus with a currency calculation function. Various programs necessary for the control of Step 1 are stored. Then, the CPU 32 executes the ROM
Various calculations are performed on the basis of various programs stored in the.

The CGROM 33 has a keyboard 3
Dot image data corresponding to code data of each character, number, etc. inputted from each key above is stored,
The dot image data read from the CGROM 33 based on the code data of characters and the like stored in the text memory 37 is then transferred to the image buffer 39.

Further, the RAM 35 as storage means is
The RAM 35 temporarily stores various calculation results calculated by the PU 32. As shown in FIG. 3, the RAM 35 includes a text memory 37, a text pointer 38, an image buffer 39, and a work area. Various memory areas such as 40, a conversion table area 41 for storing a currency conversion table, and an input / output currency storage area 42 are provided. It should be noted that the data stored in the conversion table area 41 and the like should not be deleted inadvertently.
It is desirable that an auxiliary power supply (not shown) is connected to the AM 35.

Here, the text memory 37 as a storage area stores code data corresponding to characters, numerals, symbols, and the like input from the keyboard 3 as text (document data). The text pointer 38
Is a pointer for sequentially instructing each code data stored in the text memory 37.
Since each code data can be sequentially specified when each code data is read out from the, it can be used, for example, in searching for the immediately preceding numeric string data in the text memory 37. The image buffer 39 has the CGR as described above.
The dot image data read from the OM 33 is transferred and stored. The thermal head 19 performs dot printing according to the dot image data stored in the image buffer 39. Incidentally, the image buffer 39 is constituted by a so-called ring buffer. The input / output currency storage area 42 stores an input currency and an output currency set in an input / output currency setting process described later.

A work area 40 as a work area
Is an area for acquiring and storing the immediately preceding numeral string data from the code data corresponding to each character, numeral, or the like stored in the text memory 37. The numeral string data is stored in the currency conversion table area 41. Using the stored currency conversion table, the value is converted into the amount of currency of a certain country into the amount of currency of another country, and then returned to the text memory 37. Thereby, when the numeric string data is obtained from the text memory 37, the text memory 37 stores
The number string data immediately before input from the keyboard 3 no longer exists, and the number string data is returned to the text memory 37 after being converted to the amount of currency of another country as the amount of currency of the country which is the work area 40. It is. Therefore, in the text memory 37, instead of the numerical data input from the keyboard 3, data converted into the amount of currency of another country exists together with the code data corresponding to the characters and symbols.

The control device C has a keyboard 3 via an input / output interface 30, a liquid crystal display (LCD) 4, and a display controller (LC).
DC) 36 are connected via the input / output interface 30. Therefore, the key 6 of the keyboard 3
When a character or the like is input via the keyboard, the text (document data) is sequentially stored in the text memory 37 and input via the keyboard 3 based on the dot pattern generation control program and the display control program. A dot pattern corresponding to a character or the like is displayed on the liquid crystal display 4. Further, the thermal head 19 is connected to the control device C via a drive circuit 43.
Since the tape feed motor 45 is connected via the drive circuit 44, the thermal head 19 and the tape feed motor 4
5 is driven via drive circuits 43 and 44, respectively. Therefore, the thermal head 19 prints the dot pattern data stored in the image buffer 39,
In synchronization with this, the tape feed motor 45
The feed control of the tape with character 23 is performed via the.

Next, the operation of the printing apparatus 1 with the currency calculation function configured as described above will be described with reference to FIGS. First, the main processing performed by the printing device 1 with the currency calculation function will be described with reference to FIG.
FIG. 4 is a flowchart of the main processing program. First, in step (hereinafter abbreviated as S) 1, initialization (initialization) such as clearing of each memory area in the RAM 35 is performed, and subsequently, in S2, It is determined whether or not there is a key input from each key 6 arranged on the keyboard 3.

If there is no key input from the keyboard 3 (S2: NO), the process returns to S2, and it is determined whether or not there is a key input again. If there is a key input for any of the keys 6 (S2: YES), the CPU 32 determines whether or not the key input is the currency conversion key 9 alone (S3). If the currency conversion key 9 has been pressed alone (S3: YES), C
After performing the currency calculation process (S4) described later, the PU 32 returns to S2.

If the currency conversion key 9 has not been pressed alone (S3: NO), the CPU 32 determines whether or not the key 6 for creating a text composed of characters, numbers and the like has been pressed. Here, if the key input is from the key 6 (S5: YES), the text memory 37
After the text processing (S6) for inputting text such as characters and numbers is performed, the process returns to S2. As a result, the code data corresponding to the character or the like input from the character key 6a is stored in the text memory 37, and a text is created. Next, the CPU 32 determines whether or not the print key 7 has been pressed (S7). If the print key 7 has been pressed (S7: YES), the printing process (S8) is performed, and the process returns to S2.

If the print key 7 has not been depressed (S7: NO), the CPU 32 determines whether or not the key input is simultaneous depression of the code key K3 and the currency conversion key 9. (S9). When the code key K3 and the currency conversion key 9 are pressed simultaneously (S9: YE
S) After the currency setting process (S10) is performed, the process returns to S2. Specifically, in the currency setting process, the CPU 32 enters a table creation function mode (described later) for creating a currency conversion table. If the code key K3 and the currency conversion key 9 are not pressed at the same time (S9: NO), CP
U32 determines whether the key input is simultaneous depression of the code key K3 and the symbol key K2 (S1).
1). If the code key K3 and the symbol key K2 are pressed at the same time (S11: YES), the process returns to S2 after the input / output currency setting process (S12) is performed. Code key K
3 and the symbol key K2 are not pressed simultaneously (S
11: NO), the CPU 32 performs other processing (S13). More specifically, in the case of a key input of another key arranged on the keyboard 3, for example, a cursor key K1, a line feed key 8, or the like, after performing a process corresponding to the pressed key, S2 is executed. Return to The above is the main processing performed in the printer 1 with the currency calculation function.

Next, the currency setting process performed in S10 will be described with reference to FIGS. FIG. 5 is a flowchart of the currency setting processing program of the embodiment, and FIG. 6 is a diagram showing a currency conversion table of the embodiment. If S20 to S22 in this flowchart are first summarized, the currency conversion rate is input after the currency symbol is input in S20 (S21), and these currency symbols and the currency conversion rate are stored in the conversion table area 41. The currency conversion table is sequentially input to the table (S22). This currency conversion table is created by the user. In order to perform the currency conversion process, when the power of the printing apparatus 1 with the currency calculation function is turned on,
It is desirable that the process of S10 in FIG. 4 be performed. The reason why the user inputs the currency conversion rate in this manner is that the currency conversion rate fluctuates every day, and it is appropriate to leave the currency conversion rate at which time to use to the user.

More specifically, when the user presses the code key K3 and the currency conversion key 9 simultaneously, as described above, the apparatus enters the table creation function mode for creating the currency conversion table shown in FIG. When the user presses the symbol key K2, the liquid crystal display 4 displays a currency symbol, for example,
Since any of ¥ (yen), DM (mark), £ (pound), etc. is displayed in order, for example, "￥ (yen) mark"
Is displayed on the liquid crystal display 4, and the line feed key 8
Is pressed, the data of the “￥ (yen) mark” is stored in the conversion table area 41. If necessary, the key may be input using the key 6 for inputting a currency symbol such as $ (yen). Thus, "￥ (yen)
After the data of “Mark” is input, the liquid crystal display 4 displays a state in which a currency exchange rate can be input. The user can use the numeric keys 6b for inputting numbers and the like to enter a specific currency. Enter the exchange rate of When the line feed key 8 is pressed, the data is stored in the currency conversion table in the conversion table area 41 so as to be entered in the currency conversion table entry field of FIG.

Next, the CPU 32 determines whether there is a next currency (S23). Here, the user sets the symbol key K2
Is pressed, the CPU 32 determines that there is a currency to be input (S23: YES), and returns to S20. On the other hand, when the user presses the line feed key 8, the CPU 32 determines that there is no currency to be input (S23: NO), and the currency setting processing program ends. As a result, the currency symbol and the currency exchange rate for each country are entered in the currency conversion table entry column of FIG. 6, and the currency conversion table is completed. The reason that the user created the currency conversion table in this way is that if the currency symbol is prepared for each country and the currency conversion table corresponding to all countries in the world is prepared in advance, most users will use it. It is desirable to create currency symbols, which are highly likely to be used by users, if necessary, in advance. This is because the currency symbol is desirably created by the user at any time and entered in the currency conversion table entry field in FIG.

Next, the input / output currency setting process performed in S12 will be described with reference to FIG. FIG. 7 is a flowchart of an input / output currency setting processing program executed when the user simultaneously presses the code key K3 and the symbol key K2. In this process, first, the CPU 32
Determines whether there is data such as a currency symbol and a currency conversion rate in the currency conversion table (S25), and if there is no data in the currency conversion table (S25: NO), terminates the program of this processing. . In this case, a warning sound is generated as necessary, or a warning message is displayed on the liquid crystal display 4 to notify the user that there is no data such as a currency symbol in the currency conversion table. You may.

On the other hand, if data such as a currency symbol and a conversion rate is input to the currency conversion table (S25: YE
S), the currency at the time of input, that is, the "currency unit" before currency conversion is selected from the currency symbols in the currency conversion table (S26), and the selected currency symbol is used as the currency at the time of input and output as the input / output currency storage area. 42 (S27). The processing of S26 and S27 will be specifically described.
At step 32, one of the currency symbols stored in the conversion table area 41 is read out, and the currency symbol is displayed on the liquid crystal display 4 together with the character string "input currency". Then, in response to the pressing of the cursor key K1, the currency symbol stored in the conversion table area 41 is read, the currency symbol displayed on the liquid crystal display 4 is changed, and at the time when the line feed key 8 is pressed, The displayed currency symbol is used as an input currency as the input / output currency storage area 42.
To memorize.

Therefore, the user depresses the cursor key K1 to display a currency symbol corresponding to the desired currency unit before the currency conversion on the liquid crystal display 4, and when the desired currency symbol is displayed, a line feed key 8 is displayed. By pressing, the currency unit before currency conversion can be set. When the process of S27 is completed, the currency at the time of output (at the time of printing or display), that is, the "currency unit" after currency conversion is selected again from the currency symbol in the currency conversion table (S28), and is selected. The currency symbol is stored in the input / output currency storage area 42 as the currency at the time of output (S29).

If the output currency is to be set (S30: NO), S28 and subsequent steps are executed again. On the other hand, if the setting of the output currency is completed (S30: YE
S), the input / output currency setting process ends. This S2
8, the processing of S29 will be specifically described.
First, one of the currency symbols stored in the conversion table area 41 is read, and the currency symbol is displayed on the liquid crystal display 4 together with a character string “input currency”.
Then, in response to the pressing of the cursor key K1, the currency symbol stored in the conversion table area 41 is read, the currency symbol displayed on the liquid crystal display 4 is changed, and at the time when the line feed key 8 is pressed, The displayed currency symbol is stored in the input / output currency storage area 42 as an output currency.

Then, the CPU 32 displays a message prompting the user to input whether or not to end the setting of the output currency, such as “setting completed?”, And further inputs the character “N”. If you enter to set
The process of S28 is executed, and the currency symbol is displayed on the liquid crystal display 4 together with the character string of "output currency". On the other hand, when the user inputs a letter “Y” or the like to indicate that the setting of the output currency is to be ended, the input / output currency setting processing ends. Therefore, the user presses the cursor key K1 to display a currency symbol corresponding to a desired currency unit after the currency conversion on the liquid crystal display 4, and presses the line feed key 8 when the desired currency symbol is displayed. Thus, the currency unit after currency conversion can be set.

Next, the currency conversion process performed in S4 will be described with reference to FIG. FIG. 8 is a flowchart of a currency conversion processing program executed when the user presses the currency conversion key 9 alone. In this case, for example, in order to create a US currency price tag “chocolate $ dollar” corresponding to “chocolate 1500 yen”,
The user inputs “chocolate 1500” into the text memory 37 using the key 6. In the input / output currency setting process, the printing device 1 with the currency calculation function displays the “currency unit” before currency conversion and the “currency unit” after currency conversion on the liquid crystal display 4 so that the user can individually Since it is possible to select, the user can set in advance the "Japanese currency unit (yen)" before currency conversion and the "US currency unit (dollar)" after currency conversion.

The CPU 32 determines whether or not a number has been input from texts such as all characters stored in the text memory 37 (S41). If there is no input of a number in the text memory 37 (S41: NO), the currency conversion process cannot be performed, so the CPU 32 ends this flowchart. In this case, if necessary, a warning sound is issued to the user, or a warning message is displayed on the liquid crystal display 4 to notify the currency conversion table that the currency conversion processing cannot be performed. May be. When there is a numeric input in the text memory 37 (S41: YE
S), the CPU 32 acquires the immediately preceding numeral string data from the text memory 37 (S42). Specifically, the CPU 3
2 is the last digit string data “15” from the text memory 37.
00 ”is removed and moved to the work area 40. Next, C
The PU 32 reads the currency symbol of the input currency stored in the input / output currency storage area 42 from the currency conversion table stored in the conversion table area 41, and acquires a currency conversion rate corresponding to the currency symbol (S43). ).
Then, it is determined whether or not the conversion rate is "1" (S
44). When the conversion rate is "1" (S44: YE
S) Since the input currency is set to the base currency used when the conversion table was created, the process proceeds to S46 without executing S45 described later.

On the other hand, if the conversion rate is not "1" (S
44: NO), the input currency is set to a currency other than the base currency when the conversion table was created.
In order to convert the numeric string obtained in S42 into the basic currency, the conversion is performed according to the conversion rate obtained in S43 (S45) and stored in the work area 40. And S
Move to 46. In S46, the CPU 32 reads the currency symbol of the output currency stored in the input / output currency storage area 42 from the currency conversion table stored in the conversion table area 41, and acquires the conversion rate corresponding to the currency symbol ( S43). Then, the numerical string obtained in S42 or converted in S45 and stored in the work area 40 is converted according to the conversion rate obtained in S46 (S47).

In the above case, since the numeric string data “1500” is the “currency unit of Japan” before the currency conversion, and the currency conversion to the “currency unit of the United States” is set in advance by the user. It is determined from the currency conversion table that the conversion rate is “1”, and S46 is executed without executing S45, and “126.68 yen in Japan” which is the conversion rate of the output currency is changed to “1. One dollar in the United States "can be read. Then, the CPU 32 calculates according to the read conversion rate (S47). That is, the numeric string data “1500” is converted into the currency conversion rate “1”.
26.68 "to obtain a calculation result of" 11.84 ". Thereafter, the CPU 32 appropriately adds a currency symbol, a scale mark, a decimal point mark, a delimiter space, and the like to the calculation result as needed (S48). That is, a currency symbol such as “$ 11.84” is added. still,
"Currency symbol, scale mark, decimal mark, delimiter space, etc." is displayed differently in each country. Therefore, these are registered in the RAM 35 or the like in advance, and the "currency symbol, Display of scale mark, decimal mark, delimiter space "is added as appropriate.

Here, the CPU 32 operates as a text memory 37.
It is determined whether or not data can be input to (S49). This means that if data cannot be input to the text memory 37,
The printing device 1 with the currency calculation function is a suitable character-equipped tape 2
3 may not be created, so as to prevent this. When the CPU 32 determines that the text memory 37 is full and data cannot be input into the text memory 37 (S49: NO), the CPU 32 sets the text data to “1”.
500 ”(S50), and the CPU 32 displays on the liquid crystal display 4 that the text memory 37 has a memory full error (S51). The user who sees the display makes an appropriate correction, and the CPU 32 returns to the flowchart of FIG.

When data can be input into the text memory 37 (S49: YES), the CPU 32 inputs the data into the text memory 37. Thereby, “chocolate $ 11.84” is displayed on the liquid crystal display 4. Thereafter, the CPU 32 determines whether or not to perform conversion to the next set output currency (S53). If there is no next conversion (S53: NO), the CPU 32 ends the processing of the flowchart of FIG. 8, and then executes the flowchart of FIG.

If there is the next conversion (S53: YES),
Returning to S46, the CPU 32 performs the steps from S46. Specifically, for example, “Chocolate 1500” is stored in the text memory 37, and when the British pound is set in addition to the US dollar as the output currency, “Chocolate $ 11.84” is stored in the text memory. After being returned to 37, the same processing is performed for British pounds, and, for example, “chocolate $ 11.84 £ 7.02” is stored in the text memory 37. Thereafter, when the user presses the print key 7, C
The PU 32 executes the printing process (S8) of FIG. 4, and when the printing process by the thermal printing mechanism PM is completed,
Return to S2.

As another embodiment, for example,
The case where a price tag for chocolate "Chocolate @ Pound" for "Chocolate $ 10" is prepared will be described.
"Chocolate 10" is input. Then, the user simultaneously presses the code key K3 and the currency conversion key 9 (S11: YES), and outputs the "US currency unit (dollar)" before currency conversion and the "UK currency unit (currency unit) after currency conversion. (Pound) "(S12). Next, when the user presses the currency conversion key 9 alone, a currency calculation process (S4) is executed. Since there is a numeric input in the text memory 37 (S41: YES), the CPU 32 acquires numeric string data from the text memory 37 (S42) and moves to the work area 40. Then, from the currency conversion table of FIG. 6, the conversion rate of the dollar as the input currency is obtained (S4).
3). This conversion rate is not “1” (S44:
NO), the CPU 32 converts the numeral string “10” into the base currency according to the acquired conversion rate (S45). Next, from the currency conversion table, the conversion rate of the pound which is the output currency is obtained (S46), and the conversion of the numeric string "10" into the base currency is performed according to the obtained conversion rate (S47).

More specifically, the CPU 32 determines in step S43 that the conversion rate of the currency conversion table “12
It is read out that “6.68 yen” is “US $ 1”, and in S45, the numeric string data “10”, which is US dollars, is converted into the numeric string “1266.8,” which is Japanese yen, according to this conversion rate. And stores it in the work area 40. Next, in S46, the CPU 32 determines that the conversion rate of the currency conversion table, “213.43 of Japan”
It reads that "yen" is "1 pound of Britain" and S4
In step 7, in accordance with the conversion rate, the number string "1266.8" converted into Japanese yen is converted into the number string "5.94" which is British pound. After that, the CPU 32
Adds a currency symbol, a scale mark, a decimal point mark, a delimiter space, and the like to the calculation result as needed (S48). That is, a currency symbol or the like is added, such as “£ 5.94”, and steps S49 to S53 are executed to display “chocolate £ 5.94” on the liquid crystal display 4 (S52).

As described above in detail, according to the printing device 1 with the currency calculation function according to the present embodiment, the key 6 for inputting text composed of characters, numerals, etc., , A currency conversion key 9 used to convert a currency amount of a certain country into a currency amount of another country, and a work area 40 when the currency conversion key 9 is pressed. A CPU 32 for converting the stored number into a currency amount of a certain country into a currency amount of another country, and a thermal printing mechanism PM for printing data such as characters stored in the text memory 37 and the converted amount. Is provided. Then, text consisting of characters, numbers, and the like input via the keyboard 3 is stored in the RAM 35, and the CPU 32 sets the number stored in the work area 40 as a predetermined amount in a certain country to the amount of currency in another country. Since the conversion is performed, the thermal printing mechanism PM can print text composed of characters, numerals, and the like stored in the RAM 35. Thus, after the user inputs various texts including the input amount into the text memory 37, it is later necessary to convert the input amount of one country in the text into the amount of currency of another country. Even if you notice, if you operate the currency conversion key 9, the previously entered numerical value will be converted into the amount of the currency of another country as the input amount of one country, so there is no need to repeat the input operation again. Become.

It should be noted that the present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the spirit of the present invention. In the case of the above embodiment, data such as “100 yen” is stored in the RAM 35.
Or the like, the numeric data such as “100” may simply be obtained from the text memory 37 as a storage area, or “10” as necessary.
Both the numerical data such as "0 yen" and the currency unit symbol may be acquired. The operation member may be other than the currency conversion key 9, and the storage means may be a storage medium other than the RAM. Further, the printing means may be other than the printing mechanism PM. In addition, the printing device 1 with a currency calculation function displays “amount of currency of one country”
And a price tag in which "amount of currency in another country" is printed, or a price tag other than the price tag may be generated.
