However, the conventional numerical display device described above has the following problems.

First, as the numerical values to be displayed, in many cases natural numbers such as quantities and monetary amounts are displayed. For example, the number of display digits of a calculator is generally 8 to 12 digits. By the way, in recent years, virtual currencies such as bitcoin have become popular, and various transactions using virtual currencies have come to be widely performed. In this case, the virtual currency has no substance and is a virtual currency. Therefore, not only natural numbers of 1 or more but also up to about eight decimal places are used in many cases. As a result, the total number of display digits including natural numbers is considerably increased, which cannot be handled by conventional numerical display devices.

Secondly, in the case of virtual currency, it is expected that the number of digits after the decimal point will increase further in the future. Because it remains at 1, it is difficult to grasp the exact figures, and the risk of misinterpretation increases. Especially in currency transactions, mistakes in entering or reading numbers can lead to serious losses. It is not necessarily sufficient from the viewpoint of ensuring ease of confirmation for the user, and there is room for further improvement.

SUMMARY OF THE INVENTION An object of the present invention is to provide a numerical display device that solves the problems existing in the background art.

In order to solve the above-described problems, the numerical value display device 1 according to the present invention is a display device for displaying a numerical value P including at least a decimal fraction Nd below the decimal point on a predetermined display unit 2, wherein the period Sp and the symbol data related to a specific symbol Sd, which is composed of a plurality of preset segments that are used to separate the digits of a natural number of 1 or more, other than the comma Sk, and that are used to separate the decimal numbers Nd less than 1; When displaying a numerical value P containing a decimal Nd less than 1 with a preset digit grouping place for a decimal Nd less than, some segments of the particular symbol Sd are replaced with the corresponding place of the decimal Nd and a display processing unit 3 that performs data processing for displaying as a digit separator in the display unit 2 and performs display processing on the display unit 2 .

On the other hand, according to a preferred aspect of the present invention, the specific symbol Sd is arranged between the arranged decimal numbers Nd and the decimal numbers Nd, and is composed of three segments, the upper part Xu, the middle part Xm, and the lower part Xd, and the middle part Xm is A circular period Sp may be formed, the upper portion Xu may be formed into a triangular shape with a pointed upper end, and the lower portion Xd may be formed into a triangular shape with a pointed lower end. At this time, it is desirable to display the specific symbol Sd at a position below the decimal number Nd.

According to the numerical display device 1 according to the present invention, the following remarkable effects can be obtained.

Predetermined symbols other than the period Sp used for the decimal point and the comma Sk used to separate the natural numbers of 1 or more are set in advance as the specific symbols Sd used to separate the decimals Nd of less than 1, Set the digit separator for the decimal Nd, display the decimal Nd less than 1 when displaying the numerical value P, and when the set digit separator occurs, the specific symbol Sd and the decimal Nd Since it is displayed as a digit separator at the position corresponding to ..., even if the number of digits after the decimal point is large, the ease of confirmation (ease of recognition) of the whole numerical value P can be improved. can be done. As a result, erroneous input or reading of the numerical value P can be avoided, and serious losses which may occur in transactions or the like in such applications can be prevented.

Next, preferred embodiments according to the present invention will be presented and explained in detail based on the drawings.

First, the configuration of the display device 1 according to the present embodiment will be specifically described by taking a calculator 10 as an example with reference to FIGS. 1 to 5. FIG.

FIG. 3 shows an external configuration of a calculator 10 having the same display device 1. As shown in FIG. The illustrated calculator 10 has a keyboard section 12 arranged in the lower half section 11 d of the panel section 11 . This keyboard unit 12 can be configured as a general keyboard, and includes ten numeric keys Kn, a period key Kp indicating a decimal point, calculation keys Ka, Kb, Kc, Kd, a clear key and a memory key. Various function keys Kx are included. In the upper half portion 11u of the panel portion 11, a solar panel 13 for generating photovoltaic power is arranged in the upper portion, and a display portion (display ) 2 are placed. The display unit 2 constitutes a part of the main part of the display device 1, and an example is a liquid crystal display panel.

FIG. 1 shows the display unit 2 extracted and enlarged. As described above, the conventional electronic calculator displays generally display 8 to 12 digits. However, the display unit 2 used in this embodiment is designed to display up to 15 digits. In the amount processing of virtual currency, in addition to the display of a natural number of 1 or more, it is not uncommon to use up to about 8 digits after the decimal point. is desirable. In this way, if at least 13 digits or more can be displayed, even in applications where 8 digits or more after the decimal point are used, such as virtual currency amount processing, together with the display of natural numbers of 1 or more A sufficient display can be made. Therefore, in particular, it is possible to sufficiently cope with numerical display in various fields including the display of monetary amounts of virtual currency.

Each number N is composed of a combination of seven segments sm . A delimiter portion SX is displayed between the number N and the number N adjacent to it. The delimiter part SX shown as an example is arranged at a position Hd below the number N, and is composed of three segments, an upper part Xu, a middle part Xm, and a lower part Xd. In this case, the middle Xm is displayed as a circular period Sp. The lower portion Xd is formed in a substantially isosceles triangle shape with a pointed lower end, and is combined with the middle portion Xm to display a comma Sk. The upper part Xu is displayed as a specific symbol Sd by combining with the middle part Xm. The exemplified specific symbol Sd is formed such that its upper and lower shapes are line symmetrical with respect to the comma Sk.

4(a) to 4(c) are extracted and enlarged views showing display modes of the delimiter portion SX corresponding to different uses. In this case, FIG. 4(a) is a case of displaying as a comma Sk, and the middle part Xm and the lower part Xd are displayed. FIG. 4(b) shows a case where the period Sp is displayed, and only the central portion Xm is displayed. FIG. 4(c) shows a case where the specific symbol Sd is displayed, and the middle part Xm and the upper part Xu are displayed. Thus, in particular, for the specific symbol Sd, the period Sp used for the decimal point and the comma Sk used to separate the digits N of 1 or more are used for predetermined symbols other than the period Sp and the comma Sk. , with different sizes and positions. As a result, as will be described later, it can be used as a digit separator for decimals Nd less than 1.

Note that the punctuation symbol part SX shown in FIG. 1 (FIG. 4) is shown as an example, and such a punctuation symbol part SX can be implemented in various forms. FIGS. 5(a)-(c) show application examples of the delimiter part SX. FIG. 5(a) shows an example in which the specific symbol Sd is arranged at the position Hu above the number N, and the shapes of the specific symbol Sd and the comma Sk are slightly different from those in FIG. In this case, the specific symbol Sd is formed into a single shape as a whole, and the comma Sk is displayed in combination with the period Sp. FIG. 5(b) shows an example in which both the specific symbol Sd and the comma Sk are arranged at the upper position Hu of the number N, and the overall shapes of the specific symbol Sd and the comma Sk are slightly different from each other. In addition, the specific symbols Sd, commas Sk, and periods Sp all project upwards or downwards relative to the number N. This makes it easier to distinguish between numbers N including decimals Nd. The method of displaying the specific symbol Sd and the comma Sk is the same as in FIG. 1 (FIG. 4). FIG. 5(c) shows an example in which both the specific symbol Sd and the comma Sk are formed in a single shape.

Thus, the entire delimiter portion SX including the specific symbol Sd can be implemented in various shapes, designs, modes, layouts, etc., including FIGS. 1 and 5(a) to (c). In particular, the specific symbol Sd can be displayed at a position Hu above the number N or a position Hd below the number N between the numbers N arranged. Therefore, various display methods can be selected, and a high degree of freedom in design including usability and design can be ensured, contributing to the improvement of development potential and marketability.

On the other hand, FIG. 2 shows the internal configuration of the calculator 10, that is, the configuration of the electrical processing system by means of a block system. In the electric processing system, the display unit (display) 2, the keyboard unit 12 and the solar panel unit 13 are the same as those shown in the external view described above. Reference numeral 20 denotes a computing processing unit including a CPU (processing unit) 21 and a memory (storage unit) 22 as main parts, and is capable of performing various data processing. In this case, the memory 22 has at least a data area for temporarily storing or storing data and a program area for storing a processing program 22p that functions as a calculator. The CPU 21 cooperates with the memory 22 to perform various calculations and controls.

In the calculator 10, the display unit 2 and the computing processing unit 20 (CPU 21, memory 22) in particular constitute the display device 1 according to this embodiment. Therefore, the display unit 2 can display a 15-digit number N, as described above, and has a function of displaying a numerical value P including at least a decimal fraction Nd. Further, the CPU 21 and the memory 22 constitute the display processing unit 3, and in the memory 22, various data necessary for the calculator are registered, and in particular, symbol data related to the specific symbol Sd described above according to the present invention is registered. do.

Further, the display processing unit 3 displays the above-described specific symbol Sd as a digit separator at the position corresponding to the decimal number Nd . It also has a processing function for performing data processing and displaying on the display unit 2 . In the case of the example, the specific symbol Sd is displayed by dividing the decimal number Nd below the decimal point into units of three digits. Therefore, as the digit separator, the digit is set in units of three digits.

In this way, when displaying the specific symbol Sd, if the decimal number Nd below the decimal point is divided into units of three digits, the comma Mk conventionally used to display a natural number of 1 or more can be used. Since display at the same level can be performed, it can be implemented as an optimum form from the viewpoint of easily and reliably recognizing a numerical value P including a decimal Nd.

Next, functions (operations) of the numerical value display device 1 according to the present embodiment will be described according to the flowchart shown in FIG. 6 while referring to FIGS. 7 and 8. FIG.

Note that the following description is limited to the method of displaying the numerical value P according to the present embodiment, and functions related to the calculator 10 are omitted.

First, it is assumed that a number (numerical value P) is key-inputted from the keyboard unit 12 (step S1). In this case, the operator presses any numeric key Kn (step S2). This key input is given to the CPU (processing unit) 21 . Thereby, according to the processing program 22p, the CPU 21 determines whether or not the decimal point has already been input (step S3). At this point, since the key input is the first numeric input, it is determined that there is no decimal point input. That is, it is determined that the input is a numeric input (step S4).

As a result, the first number N is displayed on the display section 2 (step S5). That is, in the example of FIG. 7, "1" is displayed first, and in the example of FIG. 8, "7" is displayed first. 7 shows an example of displaying a numerical value P including a decimal point, and FIG. 8 shows an example of displaying a numerical value P without a decimal point. Also, the number of input numbers N... (or decimal Nd...) is counted, and it is determined whether or not the number of inputs has reached "3" (steps S6 and S7). At this time, since this is the first number input, the count number is "1". This completes the first input process.

Next, if there is a second numeric input, the same numeric input processing as described above is executed (steps S1 to S7). As a result, the next "5" is displayed in the example of FIG. 7, and the next "1" is displayed in the example of FIG. Then, the count number of the number becomes "2".

Next, it is assumed that the third input is performed and the period key Kp is pressed at this time. In this case, since it is determined that the input is a decimal point input rather than a numeric input, a period Np is displayed as shown in FIG. 7 (steps S8 and S9).

Next, when the fourth numeric input is performed, the decimal point has already been input, so the decimal point input routine, that is, the routine from step S10 onwards is performed. In this case, according to the display of FIG. 7, the input number N is displayed on the display section 2 as a decimal number Nd (steps S3 and S10). In this case, as shown in FIG. 7, "4" is displayed as the decimal number Nd, and the count number for the natural number N is reset. Also, the input of the decimal number Nd is counted, and it is determined whether or not the count number has reached "3" (steps S11 and S12). At this point, the count number is "1" because it is the first decimal Nd input. This completes the first input processing of the decimal number Nd.

Next, if there is a fifth number input, similar processing relating to input is performed (steps S1 to S3, S10 to S12). As a result, in the example of FIG. 7, the next "7" is displayed and the count number becomes "2". This completes the second input processing of the decimal number Nd. Further, if there is a sixth number input, similar processing relating to input is performed (steps S1 to S3, S10 to S12). As a result, in the example of FIG. 7, the next "2" is displayed and the count number becomes "3". When the count number becomes "3", the display process of the specific symbol Sd is started, and the count number is reset to "0" at this point (step S13). In this case, the specific symbol Sd is not displayed at this time, but is displayed when the next decimal Nd is entered. This completes the third input processing of the decimal number Nd.

Next, if there is a seventh number input, similar processing relating to input is performed (steps S1 to S3, S10 to S12). As a result, the next "3" is displayed in the example of FIG. Also, at this point in time, the display of the specific symbol Sd based on the display processing of the specific symbol Sd is performed before this "3". Note that the count number is "1".

Next, if there is an eighth, ninth, etc. number input, the same processing related to decimal input is sequentially performed (steps S1 to S3, S10 to S12). In the example of FIG. 7, the next "3" and "1" are displayed in sequence. Therefore, FIG. 7 shows a state in which "15.473-31" is finally displayed as the numerical value P.

On the other hand, it is assumed that the next number is input without pressing the period key Kp at the time of the third key input (step S4). In this case, since it is not judged as a decimal point input, "3" is displayed as shown in FIG. Also, the count number is "3". Therefore, at this point, the display process of comma Sk is started and the count number is reset to "0" (steps S7 and S14). In this case, the comma Sk is not displayed at this time, but is displayed when the next number N is entered. This completes the third number N input process.

Next, if there is a fourth number input, similar processing relating to input is performed (steps S1 to S5). As a result, in the example of FIG. 8, the next "7" is displayed, and a comma Sk is displayed before the third digit "5" from "7". Also, the count number becomes "1". The display in this case is a conventionally known display method, and is generally displayed before the number N of "third digit x D (D is 1, 2, 3...)". FIG. 8 shows a case where "1", "8" and "0" are sequentially input thereafter. Therefore, FIG. 8 shows a state in which "7, 137, 180" is finally displayed as the numerical value P. Then, when all the numbers N... or the decimals Nd... related to the target numerical value P to be input are completed, the series of step processing relating to the display method is completed (step S1).

As described above, the numerical value display device 1 according to the present embodiment has, as a basic method (means), a predetermined symbol other than the period Sp used for the decimal point and the comma Sk used for separating 1 or more natural numbers. is set as the specific symbol Sd used to separate the decimals Nd less than 1, and the place of separation for the decimals Nd less than 1 is set. is displayed, and when the set digit separator occurs, the specific symbol Sd is displayed as a digit separator at the position corresponding to the decimal Nd . . . Even if it is a use, the easiness of confirmation (easiness of recognition) for the entire numerical value P can be further enhanced. As a result, erroneous input or reading of the numerical value P can be avoided, and serious losses which may occur in transactions or the like in such applications can be prevented. Moreover, it can be implemented easily and at low cost, and contributes to the improvement of convenience from the viewpoint of ease of recognition.

Therefore, in particular, as the numerical value P including the decimal Nd, the numerical value P related to the virtual currency can be applied. As a result, it is possible to display the amount of money related to the virtual currency, which has a high utility value as an application, so that it is possible to avoid input errors and reading errors of the numerical value P and prevent serious losses that may occur in currency transactions, etc. etc., can be used for optimal purposes.

Although the preferred embodiments have been described in detail above, the present invention is not limited to such embodiments, and detailed configurations, shapes, materials, quantities, numerical values, etc., do not deviate from the gist of the present invention. Any change, addition, or deletion can be made within the range.

For example, it is desirable that the specific symbol Sd is different from the comma Sk, but the use of the comma Sk as the specific symbol Sd is not excluded. Further, the specific symbol Sd is desirably divided into three digits with respect to the decimal point Nd below the decimal point, but may be displayed in units of two digits or in units of four or more digits, if necessary. On the other hand, the display unit 2 has shown the case of displaying 15 digits, but basically it can be configured to be able to display any number of digits of at least 13 digits and excluding less than 13 digits. is not. On the other hand, as the number N including the decimal Nd, it is preferable to apply the number N related to the virtual currency, but it can be used to display various numerical values other than the amount of the virtual currency.

INDUSTRIAL APPLICABILITY The numerical display device according to the present invention can be used to display numerical values including at least decimals below the decimal point on various display units such as calculators and computer displays.
