  In any of the default digit division pattern and the first to fifth digit division patterns, the digit division position is also shifted if the decimal point digit position is shifted in accordance with the calculation process.

  Next, the operation of the calculator with printer 10 having the above configuration will be described.

  FIG. 5A is a flowchart showing an overall process (part 1) by the calculator 10 with a printer.

  FIG. 5B is a flowchart showing the entire processing (part 2) by the calculator 10 with a printer.

  FIG. 6A is a diagram showing a specific example of a numerical value display operation with a default digit separation pattern accompanying the arithmetic processing in the calculator 10 with a printer.

  FIG. 6B is a diagram showing a specific example of the numerical value display operation in the second display pattern accompanying the arithmetic processing in the calculator 10 with a printer.

  FIG. 7 is a diagram showing a specific example of a series of numerical value printing operations accompanying the overall processing in the calculator with printer 10.

  When the [AC / ON] (clear / power) key is operated, the calculator 10 is in an operating state, and the display unit 15 displays the numeric display bodies 16a to 16l of all digits at “0” for a certain period of time. At this time, the period display bodies 17a to 17l, the comma display bodies 18a to 18l, and the prime display bodies 19d to 19l are selectively selected in accordance with the digit separator display pattern (initially “default”) currently set in the setting display mode memory 35b. Is displayed blinking (step S1).

  Further, the printing unit 16 prints out all the digits “0” on the recording paper 17 (see arrow a in FIGS. 1 and 7). At this time, a digit-separated symbol is printed in accordance with the digit-separated print pattern (initially “default”) currently set in the setting print mode memory 35a (step S2).

  Then, the memory area for calculation work such as the calculation history data memory 36 is cleared (step S3), and a display operation standby state corresponding to the key operation of the key input unit 11 is set (step S4).

  Here, when it is detected that the [DISP] key 14d of the key input unit 11 has been operated (step S5 (Yes), it is determined whether the [DISP] key 14d has been pressed for a long time (step S6). ] When the key 14d is kept pressed for a predetermined time (for example, 2 seconds) or more (step S6 (Yes)), the digit separator display pattern setting mode is entered (step S7). “SET” is displayed.

  Then, the first digit separation pattern shown in FIG. 4B is displayed on the display unit 15 (step S8).

  When the [▽] key is operated, the display unit 15 displays the second digit separation pattern shown in FIG. 4C and the third digit separation pattern shown in FIG. 4D each time the key is operated. , The fourth digit separation pattern shown in FIG. 4E is sequentially switched and displayed, and when the [Δ] key is operated, the display unit 15 displays the display shown in FIG. Are switched to the fifth digit separation pattern shown in Fig. 4E, the fourth digit division pattern shown in Fig. 4E, the third digit division pattern shown in Fig. 4D, and so on (step S9 (Yes)-> S10). ).

  By this user operation, the first to fifth digit separation patterns are switched and displayed, and the [DISP] key 14d is operated in a state where the display digit separation patterns that the user desires to use other than the default are displayed. Then (step S11 (Yes)), the data indicating the digit separator display pattern displayed on the display unit 15 is stored in the setting display mode memory 35b (step S12). Then, the digit separator display pattern setting mode is canceled.

  Thus, according to the setting mode of the digit separator display pattern (steps S5 to S12), another digit separator display that the user desires to use other than the default digit separator pattern (standard specification: Up (see FIG. 4A)). Data indicating the pattern is selected from the first to fifth digit separation patterns (standard specification: Down (see FIG. 4B) to European specification: Down (see FIG. 4F)) and stored in the setting display mode memory 35b. The

  In this state, when the user normally presses the [DISP] key 14d (step S5 (Yes) → S6 (No)), the digit-separated display pattern set in the setting display mode memory 35b each time the key is operated. However, it is switched between the digit separation display pattern other than the default desired by the user and the default digit separation display pattern (step S13), and the numerical value of the display unit 15 is displayed according to any of the switched digit separation display patterns. (Step S14).

  On the other hand, when it is detected that the [PRINT] key 14p of the key input unit 11 is operated (step S15 (Yes)), it is determined whether or not the [PRINT] key 14p is pressed long (step S16). When the key 14d is kept pressed for a predetermined time (for example, 2 seconds) or more (step S16 (Yes)), the digit separator print pattern setting mode is entered (step S17). “SET” is displayed.

  Then, the first digit separation pattern shown in FIG. 4B is displayed on the display unit 15 (step S18).

  When the [▽] key is operated, the display unit 15 displays the second digit separation pattern shown in FIG. 4C and the third digit separation pattern shown in FIG. 4D each time the key is operated. , The fourth digit separation pattern shown in FIG. 4E is sequentially switched and displayed, and when the [Δ] key is operated, the display unit 15 displays the display shown in FIG. Are sequentially switched to the fifth digit separation pattern shown in FIG. 4, the fourth digit division pattern shown in FIG. 4E, the third digit division pattern shown in FIG. 4D, and so on (step S19 (Yes) → S20 ).

  By this user operation, the first to fifth digit separation patterns are switched and displayed, and the [PRINT] key 14d is operated in a state where the digit separation patterns for printing that the user desires to use other than the default are displayed. Then (step S21 (Yes)), the data indicating the digit separation print pattern displayed on the display unit 15 is stored in the setting print mode memory 35a (step S22).

  Then, as shown by the arrow b in FIGS. 1 and 7, the digit 16 is set to the digit-separated print pattern (here, the second digit) set in the set print mode memory 35a by the printing unit 16 as shown in FIG. The data is printed on the recording paper 17 together with the digit-separated symbols according to the separation pattern (see FIG. 4C) (step S23). Then, the digit separation print pattern setting mode is canceled.

  Thus, according to the setting mode of the digit separator print pattern (steps S15 to S23), another digit separator print that the user desires to use other than the default digit separator pattern (standard specification: Up (see FIG. 4A)). Data indicating a pattern is selected from the first to fifth digit separation patterns (standard specification: Down (see FIG. 4B) to European specification: Down (see FIG. 4F)) and stored in the setting print mode memory 35a. The

  In this state, when the user normally presses the [PRINT] key 14p (step S15 (Yes) → S16 (No)), the digit-separated print pattern set in the set print mode memory 35a each time the key is operated. Is switched between the digit separation printing pattern other than the default desired by the user and the default digit separation pattern (step S24).

  Then, all the digits “0” are printed on the recording paper 17 by the printing unit 16 together with the digit-separated symbols according to any of the digit-separated printing patterns switched (step S23).

  Here, according to the user operation in the setting mode of the digit separator display pattern, for example, the second digit separator display pattern (Indian specification: Up) shown in FIG. 4C is set as the digit separator display pattern other than the default. Then, in response to the subsequent operation of the [DISP] key 14d, the default display for the digit separation shown in FIG. 4A (standard specification: Up) is displayed in the setting display mode memory 35b as the display pattern currently being set. Is stored.

  Further, according to the user operation in the digit separator print pattern setting mode, for example, the second digit separator print pattern (Indian specification: Up) shown in FIG. 4C is set and set as a digit separator print pattern other than the default. It is assumed that data indicating the second digit separator display pattern (Indian specification: Up) is stored in the print mode memory 35a.

  When a calculation operation of [200 × 1350 =] is performed from this state as shown in FIG. 6A (step S25 (Yes)), a numerical value process and a calculation process corresponding to the calculation operation are executed (step S26). ).

  Then, the numerical value and the result of the arithmetic processing are written from the calculation history data memory 36 in the RAM 33 to the display memory, and the default digit separator display pattern (standard pattern) set in the setting display mode memory 35b is displayed on the display unit 15. In accordance with (Specification: Up), the numeric value and the numerical value of the calculation result are displayed (step S27).

  Specifically, as a calculation result of the calculation operation [200 × 1350 =], as illustrated in FIG. 6A, [270′000. ] (270 (Thousand)).

  Along with this, the printing unit 16 prints the numeric value and the result of the arithmetic processing on the recording paper 17 in accordance with the second digit separator printing pattern (Indian specification: Up) set in the setting print mode memory 35a. (Step S28).

  Specifically, as shown by the arrow c1 in FIG. 7, the calculation operation and the calculation result are [200 × 1′350 = 2′70′000] (2 (Lakh “Lark”) 70 (Sahastr / Hazaar “Sahastr” / Hazard ")).

  Thereafter, as shown in FIG. 6B, when the user normally presses the [DISP] key 14d (step S5 (Yes) → S6 (No)), the default digit set in the setting display mode memory 35b is displayed. The separator display pattern (standard specification: Up) is switched to the second digit separator display pattern (Indian specification: Up) arbitrarily set by the user (step S13).

  Then, as shown in FIG. 6B, the calculation result is [2′70′000. ] (2 (Lakh “Lark”) 70 (Sahastr / Hazaar “Sahastral / Hazar”))) is switched (Step S14).

  Subsequently, when a calculation operation of [150 × 2000 =] is performed (step S25 (Yes)), the number processing and the arithmetic processing according to the calculation operation are executed (step S26), and the display unit 15 As the calculation result of the calculation operation, [3'00'000. ] (3 (Lakh "Lark")) (Step S27).

  Accordingly, the printing unit 16 causes the calculation operation and the calculation result to be [150 × 2] in accordance with the same second digit separator printing pattern (Indian specification: Up) as shown by the arrow c2 in FIG. '000 = 3'00'000] (3 (Lakh "Lark")) is printed on the recording paper 17 (step S28).

  For this reason, for example, in a process in which a user in Japan, Europe, or the United States performs a calculation operation while looking at a numerical value display on the display unit 15, misplacement of digits in the numeric value or calculation result is performed by a numerical value display separated by digits in a standard specification. Can be easily and clearly confirmed, and on the other hand, the numerical value printed by the printing unit 16 and the calculation result can be printed as numbers separated by digits according to Indian specifications, so that the record of the contents of the calculation is printed The paper 17 can be used more easily in regions such as India.

  In addition, for example, during the execution of the calculation process with the standard specification, the display with the Indian specification can be easily confirmed, and the reading error of the digits can be prevented in advance.

  Thus, the [GT] (total) key is operated in a state where [200 × 1′350 = 2′70′000] and [150 × 2′000 = 3′00′000] are calculated and printed out. When done (step S29 (Yes)), the total of the two calculation results is calculated (step S30).

  Here, for example, when the default digit separator display pattern (standard specification: Up) is set in the setting display mode memory 35b in accordance with the normal operation of the [DISP] key 14d, the calculated total is calculated as follows. [570'000] (570 (Thousand)) is displayed on the display unit 15 (step S31). At this time, “GT” of the top display body 20 in the display unit 15 is displayed.

  Accordingly, the printing unit 16 generates a second digit-separated printing pattern (Indian specification: Up), as shown by the arrow d in FIG. ) And the total symbol “GT” and the unit “Lakh” (Lark) are printed on the recording paper 17 as [5′70′000] (step S32).

  Therefore, according to the digit separation pattern switching function by the calculator with printer 10 having the above-described configuration, in addition to the conventional three-digit digit separation pattern of Western type, a plurality of types of digit separation patterns according to the country or region are incorporated. Among them, two types of preset digit separation patterns and user-specified digit separation patterns can be selected / set. These two types of digit separation patterns can be freely switched according to the user's preference and the scene to be used, and the printing and display of these patterns has been made possible, preventing misreading of digits regardless of the country or region of use. , Visibility of digits (units) and recognition time can be accelerated.

  Moreover, the two types of digit separator patterns are set separately for the display digit separator pattern and the print digit separator pattern, and the default digit separator pattern and the user-specified digit separator pattern can be freely set. Switching, enabling display and printing. For this reason, the calculation process and the calculation result can be displayed and confirmed and visually confirmed by the digit separation pattern that the user is familiar with, and when the calculation result is printed out together with the calculation process, the digit separation most suitable for the intended use is used. It can be printed as a pattern, and usability can be greatly improved.

  Also, according to the digit separator pattern switching function of the calculator 10 with a printer having the above-described configuration, when the calculator 10 is turned on, the numerical value of all digits “0” according to the digit separator display pattern currently set is displayed. 15, and a numerical value of all digits “0” in accordance with the digit-separated print pattern currently set is printed on the recording paper 17 by the printing unit 16. For this reason, with the start of use of the calculator 10, it is possible to easily check the setting states of the digit separator display pattern and the digit separator print pattern.

  Furthermore, when the calculation result is printed on the recording paper 17 together with the calculation process, the unit according to the digit separation print pattern is also printed together, so that the usability can be further improved. .

  In the above-described embodiment, the digit separator display pattern set in the setting display mode memory 35b according to the operation of the [DISP] key 14d is the default digit separator pattern (standard: Up) and the user-specified digit separator pattern. It was set as the structure switched by. Similarly, the digit separation print pattern set in the setting print mode memory 35a according to the operation of the [PRINT] key 14p is switched between the default digit separation pattern (standard: Up) and the user-specified digit separation pattern. It was. On the other hand, the two digit separation patterns may be switched according to the operation of the slide switch instead of the key operation, or may be switched according to the movement of the calculator main body detected by the acceleration sensor.

  The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention when it is practiced. Further, each of the embodiments includes inventions at various stages, and various inventions can be extracted by appropriately combining a plurality of disclosed constituent elements. For example, even if some constituent elements are deleted from all the constituent elements shown in each embodiment or some constituent elements are combined in different forms, the problems described in the column of the problem to be solved by the invention If the effects described in the column “Effects of the Invention” can be obtained, a configuration in which these constituent requirements are deleted or combined can be extracted as an invention.
