Abstract

PROBLEM TO BE SOLVED: To provide an excellent printer which converts a numeric character included in an inputted text into another numeric character which is used for the output currency even if the numeric character of the text that is inputted via keys is not identical with the basic currency that is contained in a currency conversion table. SOLUTION: A printer 1 stores a text including characters, numeric characters, etc., which are inputted via the keys 6 and a currency conversion table in a RAM, converts an input currency amount which is included in the text into the output currency amount of another country based on a conversion rate of a currency conversion table and prints the converted amount. Meanwhile, a CPU decides whether the input currency amount is identical with the basic currency of the currency conversion table. If the input currency amount is not identical with the basic currency, the input currency amount is converted into the basic currency amount based on a conversion rate of the currency conversion table. Then the CPU converts the converted amount into the output currency amount based on a conversion rate of the currency conversion table.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing apparatus for converting an amount of money for an input currency in a text into an amount of money for an output currency of another country based on a currency exchange rate and printing the same. In particular, the present invention relates to a printing apparatus that can convert a number in a text into a number for an output currency and print it even if it is not the basic currency in the currency conversion table.

[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, a currency exchange rate (for example, 1 dollar = 295.28) is set by using an amount button or the like with an operation switch on an operation panel set at an exchange rate entry position.
It is necessary to input and memorize (yen) in advance. 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) By operating the input, subtotal button, etc., the Japanese yen is calculated as $ 78284.63 (= $ 265.12 x $).

Next, a control system of the printing apparatus 1 will be described with reference to FIG. FIG. 3 is a control block diagram of the printing apparatus 1 according to this embodiment, which is configured with the control device C as a core. The control device C as a control means includes a CPU
32, CGROM 33, ROM 34, and RAM 35
These are connected to each other via a bus 31 and are also connected to the input / output interface 30.

The ROM 34 stores various programs. The ROM 34 stores a main processing program, a printing processing program, a character rearrangement processing program, a sequential printing processing program, and other programs for controlling the printing apparatus 1. Various necessary programs are stored.
The CPU 32 performs various calculations based on various programs stored in the ROM 34.

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. This currency conversion table stores currency-related information on currencies for each country. As shown in FIG. 6, an integer start position A, a scale symbol B, and an integer end position as currency-related information are stored. There are provided storage columns for C, decimal point symbol D, decimal leading position E, and decimal trailing position F, and a conversion rate storage column.

More specifically, in the currency conversion table shown in FIG. 6, the currency unit display “＄” is placed at the beginning position A of the US currency “1”, the scale display “,” is placed at the scale symbol B, and the integer end position is displayed. "No display" at the tail position C, "." At the decimal point symbol D, "No display" at the leading decimal position E, "No display" at the last decimal position F, and " 12
6.68 ”(US dollar conversion rate when Japanese yen is 1) is stored, and the numerical data“ ○ △ ▽ □.
In the case of “Δ ▽”, when the data of the US currency “1” in the currency conversion table of FIG. 6 is applied, “＄ ○, △ ▽ □. △
Is displayed or printed. Similarly, in the currency conversion table of FIG. 6, the currency unit display “No display” is displayed at the integer start position A of the German currency “2”, the scale display “.” Is displayed at the scale symbol B, and the integer end position C is displayed at the integer end position C. Means "no display",
Decimal point symbol D, decimal point display “,”, decimal point position E “no display”, decimal point last position F “DM”, conversion rate “78.05” (when Japanese yen is 1) The conversion rate of the German mark of Germany) is stored, so in the case of the numerical data “○ △ ▽ □. △ ▽”, the data of the German currency “2” in the currency conversion table of FIG. 6 is applied. , “○. △ ▽ □, △ ▽ DM”. Note that, depending on the currency, for example, “○. △ ▽ □, △ ▽
In some cases, such as "DM", a space is required between the currency unit and the number. In such a case, when creating the currency unit table, the user must add space data to the currency unit and enter it. I just need. That is, "DM" may be input. As a result, in the currency conversion process described later, space data is added when a currency unit is added, and the data is displayed or printed in a state where a space is provided between the currency unit and the number. Note that an auxiliary power supply (not shown) is desirably connected to the RAM 35 so that data stored in the conversion table area 41 or the like is not accidentally erased.

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 as the currency-related information storage means stores the currency at the time of input and the currency at the time of output set in the 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 and the like stored in the text memory 37, and stores the numeral string data in the conversion table area 41. The currency conversion table is used to convert the amount of the currency of a certain country into the amount of a currency of another country, and then return the same to the text memory 37. Thus, when the numeric string data is obtained from the text memory 37, the numeric string data immediately before input from the keyboard 3 does not exist in the text memory 37, and the numeric string data is the work area 40. It is returned to the text memory 37 after being converted into the amount of currency of another country into the amount of currency of another country. 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 printing apparatus 1 configured as described above
4 will be described with reference to FIGS. First, the main processing performed by the printing apparatus 1 will be described with reference to FIG.
This will be described with reference to FIG. FIG. 4 is a flowchart of a 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.
At 2, 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 flow returns to S2 to determine again whether there is a key input. 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 a single press of the currency conversion key 9 (S3). When the currency conversion key 9 is pressed alone (S3: YE
S), the CPU 32 returns to S2 after performing a currency calculation process (S4) described later.

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 pressed (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), the CPU 3
In step S11, it is determined whether the key input is a simultaneous depression of the code key K3 and the symbol key K2.
When the code key K3 and the symbol key K2 are pressed simultaneously (S11: YES), the input / output currency setting process (S1)
After 2) is performed, the process returns to S2. When the code key K3 and the symbol key K2 are not pressed simultaneously (S11:
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 printing apparatus 1.

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. In S21 of this flowchart, after currency-related information such as a currency unit display, a decimal point symbol, and a scale symbol is input to a currency conversion table (see FIG. 6) stored in the conversion table area 41, the currency conversion rate is changed to the currency. The data is sequentially input to the conversion table (S22).
Next, the CPU 32 determines whether or not there is a next currency (S23). Here, when the user presses the symbol key K2, the CPU 32 determines that there is a currency to be input (S2).
3: YES), and return 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, for example, in the storage column of the integer leading position A, the scale symbol B, the integer trailing position C, the decimal point symbol D, the decimal leading position E, and the decimal trailing position F in the currency conversion table of FIG. Currency unit display for each country such as “＄”, “￥”, “DM”, etc. For example, decimal symbol such as “,”, “.”, “＄”, scale symbol such as “•”, “,” etc. The currency conversion table is completed as a result of the currency-related information and the exchange rate of each currency being entered. Integer start position A
In the case of the numerical data “◇ △ Δ ◇ △. △ ▽”, means before “○”, and the scale symbol B means between “○” and “◇”. In this case, the decimal point symbol D is represented by “.”. The integer end position C means between "□" and "."
The minority leading position E means between "." And "$", and the minority tail position F means after "@". As described above, the currency conversion table is created by the user. In order to perform the currency conversion process, it is desirable that the process of S10 in FIG. And the user enters the currency conversion rate,
The currency conversion rate fluctuates every day, and it is appropriate to entrust the user with which time the currency conversion rate is to be used.In addition, currency related information such as currency unit display, decimal point symbol, scale symbol, etc. This is because it is appropriate to add and print in a mode desired by the user.

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. Then, when the user presses the symbol key K2, the liquid crystal display 4 displays “the integer start position A,
Which one of a scale symbol B, an integer end position C, a decimal point symbol D, a decimal start position E, a decimal end position F, etc. is to be input, and a currency unit display, for example, ¥ (yen), $ (US dollar), DM (German mark), £ (pound), Kr (Norwegian krone)
* Kr. (Krone in Iceland) or the like is displayed in order. For example, while the “integer head position” A is displayed on the liquid crystal display 4, the line feed key 8 is pressed, and a “$” dollar mark is displayed. Is displayed on the liquid crystal display 4 and the line feed key 8 is pressed, the data of the “$ (US dollar) mark” in the currency 1 of FIG.
Is stored.

Similarly, the user is asked which of the following is to be input: integer start position A, scale symbol B, integer end position C, decimal point symbol D, decimal start position E, decimal end position F, etc. Is displayed, the line feed key 8 is depressed while the display of the “scale symbol” B is displayed on the liquid crystal display 4, and the line feed key 8 is pressed while the mark “,” is displayed on the liquid crystal display 4. By pressing,
The data of the mark “,” is stored as “scale symbol” B in the conversion table area 41 of currency 1 in FIG. Thereafter, by repeating the same manner, the data is stored in the currency conversion table in the conversion table area 41, and the currency conversion table of FIG. 6 is completed. Therefore, the CPU 32 as the control means stores the currency-related information in the currency conversion table as the storage means through the input of the currency-related information input means including the symbol key K2, the liquid crystal display 4, the line feed key 8, and the like. Can be.

The setting for the user to create the currency unit display and the like in the currency conversion table is made by the currency unit display,
If the currency conversion table corresponding to the countries of the world is prepared in advance with the decimal point symbol, scale symbol, etc. being different for each country, the amount of data that is hardly used by the user may increase and the operability may deteriorate, Further, it is desirable that the user create the currency unit display, the decimal point symbol, and the scale symbol at any time and enter them in the currency conversion table entry field of 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, 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 a desired currency unit before the currency conversion on the liquid crystal display 4. When the desired currency symbol is displayed, the line feed key 8 is displayed. By pressing, the currency unit before currency conversion can be set. S27
Is completed, the currency at the time of output (at the time of printing and display), that is, the "currency unit" after currency conversion is selected again from the currency symbol in the currency conversion table (S28).
The selected 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, when the setting of the output currency is completed (S30:
YES), this input / output currency setting process ends. This S
28 and 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 “output 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 has input the character “Y” or the like to end the setting of the output currency, the input / output currency setting process ends. Therefore, the user presses the cursor key K1 and
The currency symbol corresponding to the desired currency unit after currency conversion is displayed on the liquid crystal display 4, and when the desired currency symbol is displayed, the line feed key 8 is pressed to set the currency unit after currency conversion. it can.

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. And the printing device 1
In the input / output currency setting process, the "currency unit" before currency conversion and the "currency unit" after currency conversion are displayed on the liquid crystal display 4 so that the user can select them individually. Can be set in advance to 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, a warning sound is issued to the user 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. It may be configured as follows.

If there is a numeric input in the text memory 37 (S41: YES), the CPU 32
Then, the immediately preceding numeral string data is acquired from 7 (S42). More specifically, the CPU 32 removes the immediately preceding numeral string data “1500” from the text memory 37 and stores it in the work area 40.
Transfer to Next, the CPU 32 sets the conversion table area 41
The currency symbol of the input currency stored in the input / output currency storage area 42 is read from the currency conversion table stored in the currency conversion table, and a currency conversion rate corresponding to the currency symbol is obtained (S43). Then, it is determined whether or not the conversion rate is "1" (S44). If the conversion rate is "1" (S44: YES), the input currency is set to the base currency used when the currency conversion table is created, and therefore, without executing S45 described later, The process moves to S46.

On the other hand, when the conversion rate is not "1" (S
44: NO), since the input currency is set to a currency other than the base currency used when the conversion table was created, the number string obtained in S42 was obtained in S43 in order to convert it into the base currency. The conversion is performed according to the conversion rate (S45) and stored in the work area 40. And
The process moves to S46. 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. I do. Then, the work area 4 is acquired in S42 or converted in S45.
The number string stored in 0 is converted according to the conversion rate acquired in S46 (S47). Accordingly, it is possible to determine whether or not the amount for the input currency is the basic currency in the currency conversion table based on whether or not the conversion rate is “1”, and the CPU 32 corresponds to the determination means. If the amount for the input currency is not a number of the base currency, the CPU 32 as the first conversion means converts the amount for the input currency to the amount for the base currency based on the conversion rate, and the converted value is converted. The amount is converted to C as the second conversion means.
The PU 32 converts the value into an amount for the output currency based on the conversion rate.

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 “U.S. currency unit” 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 currency-related information such as a currency unit display, a scale mark, a decimal point mark, and a delimiter space to a predetermined position of the calculation result (S48). That is, the calculation result of “11.8” is added to the US currency “1” in the currency conversion table of FIG.
Is applied, the result is “$ 11.8”.

More specifically, a currency-related indicator such as "$" is displayed at the beginning position A of the integer, "," is displayed at the scale symbol B, and "." Is displayed at the decimal point symbol D. Add information. In this case, since the integer end position C and the decimal end position F are "no display", there is no need to add anything. Further, since the number of digits of the integer part is three, the scale display “,” of the scale symbol B is not required. The display method of such “currency unit display, scale symbol, decimal point symbol, etc.” and the position to which it is added differs depending on each country. However, these are registered in the RAM 35 or the like in advance and added to the calculation result. The registered “currency unit display, scale symbol, decimal point symbol” display can be added as appropriate. As a result, it can be displayed and printed in a manner desired by the user, and can be viewed easily or according to preference. Therefore, when the CPU 32 performing the above operation converts the numerical data stored in the RAM 35 into the amount of the currency of a certain country into the amount of the currency of another country, the currency-related information for each currency is converted into the value of the converted currency. The control means for giving the amount is constituted.

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 returning to 37, similar processing is performed for British pounds, and, for example, “chocolate $ 11.84 £ 7.02” is stored in the text memory 37. After that, when the user presses the print key 7,
The CPU 32 executes the printing process (S8) in FIG. 4, and returns to S2 in FIG. 4 when the printing process by the thermal printing mechanism PM ends.

In 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).

Specifically, the CPU 32 determines in step S43 that the conversion rate in the currency conversion table is "12
After reading out that "6.68 yen" is "1 dollar in the United States", in S45, in accordance with this conversion rate, the numeric string "10" which is a US dollar is converted into a numeric string "1266." which is a Japanese yen. 8 "and stored in the work area 40. Next, in S46, the CPU 32 determines that the conversion rate of the currency conversion table is “213.43 yen in Japan”.
Is read as "1 pound in the UK", and in S47, the number string "1266.8" converted to the yen in Japan is converted into the number string "5.94" in British pounds according to this conversion rate. Convert. Thereafter, the CPU 32 adds a currency symbol, a scale mark, a decimal point mark,
A delimiter space or the like is appropriately added as necessary (S4
8). 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 (S5).
2).

As described above in detail, according to the printing apparatus 1 of the present embodiment, the text such as characters and numbers input from the key 6 and the currency conversion table are stored in the RAM.
35, based on the exchange rate of the currency conversion table (see FIG. 6), when converting the amount of money for the input currency in the text into the amount of money for the output currency of another country, and printing. CPU 32 (determination means) for determining whether or not the amount for the input currency is the basic currency in the currency conversion table
Based on the result of the determination by the CPU 32, if the amount for the input currency is not the base currency, the amount for the input currency is converted to the base currency based on the exchange rate of the currency conversion table (see FIG. 6). CPU 32 (1st
Conversion means) and a CPU 32 (second conversion means) for converting the converted amount and the like into an amount and the like for an output currency based on the exchange rate of the currency conversion table (see FIG. 6). Therefore, even if the amount for the input currency in the text is not the base currency in the currency conversion table, the CPU 32 converts the amount for the input currency into the amount for the base currency, and then converts the amount for the output currency into the base currency. The operability is remarkably improved because it is converted to the amount of money and printed. Further, the printing apparatus 1 inputs the currency-related information on the currency for each country at a predetermined position for the numerical data stored in the RAM 35, and stores the input currency-related information in an input / output currency storage area 42 (currency-related information). Storage means).
2 (control means) reads the currency-related information corresponding to the currency from the input / output currency storage area 42 when converting the amount for the input currency into the amount for the output currency, and converts the converted currency. Can be granted.

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 above embodiment, in the currency conversion process shown in FIG. 8, the processes of S44 to S47 surrounded by a broken line can be changed as shown in FIG. That is, in this other embodiment, after S43 ends, 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. The currency conversion rate corresponding to the currency symbol is read out (S61). Then, it is determined whether or not the currency conversion rate corresponding to the currency symbol of the input currency is “1” (S62). If the conversion rate is not "1" (S6
2: NO), a conversion rate for directly converting the input currency into the output currency is calculated from the two conversion rates read in S43 and S61 (S63). And S4
2 is converted according to the conversion rate obtained in S63 in order to convert the number string obtained in 2 into an output currency (S6).
4).

For example, “US dollar” as an input currency,
When "British pound" is set as the output currency and "chocolate 10" is entered in the text memory 37, the conversion rate "126.68" is read in S43, and the conversion rate "213.43" in S61. Is read. Since these conversion rates are all conversion rates for the base currency yen, in S63,
A conversion rate is calculated that converts US dollars directly to British pounds. That is, the conversion rate of the output currency (“213.43”) is converted to the conversion rate of the input currency (“12.43”).
The conversion rate “1.68” divided by “6.68”) is obtained as the calculation result. From this calculation result, the digit string “10” obtained in S42 is changed to “5.95” (= 10 ÷).
1.68) (S64). By the way, if the conversion rate is "1" (S62: YES), the numerical string acquired in S41 is converted according to the conversion rate read in S61 (S65). S64, S6
After the end of Step 5, the process of S48 shown in FIG. 8 is executed. still,
In this other embodiment, if the determination in S53 is “YES”, the process returns to S61.

In the case of the above embodiment, for example, “100
When data such as "circle" is stored in a storage means such as the RAM 35, numeric data such as "100" may be simply obtained from the text memory 37 as a storage area, or may be obtained as necessary. Both the numerical data such as “100 yen” and the currency unit display may be acquired. The currency-related information includes, for example, a currency unit display, a decimal point symbol, a scale symbol, and the like, and may further include, for example, a delimiter space. Further, such currency-related information may be attached to the numerical data other than at least an integer head position, an integer tail position, a decimal head position, a decimal tail position, and the like.

The storage means may be a storage medium other than the RAM. Further, the printing means may be other than the printing mechanism PM. Further, the printing device 1 includes upper and lower 2
You may print and create a price tag with "amount of currency of one country" and "amount of currency of another country" printed on the column or left and right, or even create something other than the price tag good.
