[Detailed description of the invention]

The present invention relates to a desktop calculator (hereinafter referred to as a gaming calculator) equipped with a game function. In recent years, new games with innovative ideas have been developed one after another by employing microprocessors in systems, and these game attempts have been used for example in video games, game machines, and educational equipment, and have also been used in tends to be expanded to include trains and watches. In view of this trend, the present invention aims to provide a new game calculator with a novel idea. The game calculator of the present invention is characterized by a system that increases the popularity and sales of the calculator, and also allows the operator to store information on the calculator itself that he/she wishes to keep secret so that the operator does not want third parties to know about it. The system is configured so that only the user can know the information, and furthermore, it is possible to judge the degree of matching and compete for points. Here, to give a specific example of the former, the "START" button on the keyboard of a calculator.
When a key (not shown) is operated, any number or letter from 0 to 9 AEFL will randomly appear on the display as the first symbol every other digit out of the eight digits displayed on the calculator. The numbers or letters appearing in each digit form a column as shown below, and the display of letters or numbers from 0 to 9 AEFL is repeated starting at a random position in the column.

[Table] In this way, each display content (first symbol) on the display that starts changing at the same time as the "START" key is pressed can be changed using a preset key on the keyboard, such as "0", "・", By operating the ``%'' and ``+'' keys, the display contents of A to D corresponding to these keys are stopped. In other words, pressing the ``0'' key displays the digits, pressing the decimal point ``·'' key displays the digits, and so on, the display contents are stopped. Therefore, if you set specific data (data corresponding to the second symbol) stored in ROM memory etc. in advance as EL-5-1, for example, the display contents on the calculator display section will change randomly. When a key is operated such that the symbol matches the specific data, a specific symbol such as "HAPPY", an English character using a Japanese character segment, can be output. Purchasers of the calculator can add witty ideas to the game calculator, such as writing on the user card that "HAPPY" was output and returning it to the retailer or manufacturer to receive a souvenir. In the latter case, when the above display contents match specific data, information that you do not want a third party to know (secret data) can be stored in memory and recalled. be. Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a system block diagram of an embodiment of a gaming calculator according to the present invention. In the figure, 1 is a central processing unit (CPU), 2 is a read-only memory (ROM), 3 is a readable/writable memory (RAM), 4 is a key unit with multiple keys, 5 is a display buffer, and 6 represents a display consisting of multiple digits. The CPU 1 reads the key signal or displays the contents of the RAM 3 on the display 6 according to a procedure written in the ROM 2 in advance.
In the ROM 2, procedures for reading and displaying keys and procedures for performing operations such as calculations according to numerical values or formulas written in the RAM 3 are written in advance. RAM3 is the memory that stores numbers and formulas.
Flags, counters, etc. that define various conditions used in the processing process of the CPU 1 are set in this RAM memory. 4 is the key unit and CPU1
It has a matrix configuration of a strobe signal S and a key signal K from. Display buffer 5 is CPU
The display data written by 1 is converted into a signal suitable for the display and output. FIG. 2 shows an example of the display in the game mode and some of the keys on the key unit. In the figure, four digit random numbers or characters are displayed on the display 7. This display content is displayed at regular intervals.
It is changed by the CPU 1 randomly or based on some regularity. Each key on the key unit 8 is used as a key to execute calculations in normal use, but some of the keys are displayed on the display 7 of the calculator randomly or at predetermined intervals in the game mode. It is used as a key (specific key) to stop the changing display contents. For example, the numeric value "0" key displays the content of the most significant digit of the display 7, the decimal point "・" key displays the next digit, the equal "=" key displays the next digit, and the addition "+" key displays the lowest digit. The key functions as a key to stop the displayed contents. Therefore, the operator operates these specific keys as appropriate to change the display content (first symbol) randomly displayed on the display 7 to the display content (first symbol) that has been stored in the memory in advance or that the operator has stored in the memory using the keys or the like. This means that the signal is stopped so as to match the signal corresponding to the second symbol). That is, the correspondence between each key in the figure and the displayed digits corresponds to the order of the displayed digits, as illustrated by the arrows in the figure. FIG. 3 shows a part of the RAM 3 shown in FIG. 1. Here, registers X, DT and flag S1
~S4, 1P~4P have the following meanings, respectively. X: This register is a register that stores contents to be displayed such as calculation results. DT: This register is a register that stores data that sets the cycle for changing display contents in game mode. S1 to S4: These flags are set corresponding to each digit of the display when the display contents of each digit are stopped by operating a specific key in the game mode (see FIG. 2). 1P to 4P: These flags are set in accordance with the coincidence, if any of the display contents match the memory data when the display change of each digit is stopped in the game mode. For example, the following is handled: 1P...Set when two digits match. 2P...Set when two sets of two digits match. 3P...Set when three digits match. 4P...Set when all four digits match. Next, the operation of the embodiment of the present invention will be explained based on the flowchart of FIG. 4. Step 1 is to perform initial settings for a so-called slot machine game. That is, a 4-digit random number is generated using a register in the RAM, the display contents at the start are determined, and other flags, etc. are reset. In step 2, time is counted from the start of the game, and it is determined whether or not the preset game time (DT register of RAM 3) has been exceeded. When the game time is exceeded, the game will automatically end. Steps 3 to 6 are performed when a specific key (for example, the above "0", "・", "=", "+" key) is operated to stop the display change of each digit shown in FIG. 2 during the game operation. Determine whether or not the result is correct. In steps 7 to 10, when the display change stop key for each digit is operated according to the judgment in steps 3 to 6 above,
Flags S1 to S4 corresponding to each digit are set. In step 11, when the display change stop key is operated, if there is a digit that has already stopped, a match is detected between the stopped digit and the content stored in advance in the memory ROM, and depending on the content of the match, the flag shown in Figure 3 is set. Set 1P to 4P. In step 12, it is determined whether all digits have stopped, that is, whether flags S1 to S4 are all set. If all are set, the game is ended. Step 13 counts up a register DT that determines the timing of display change. In step 14, it is determined whether the register DT has counted over or not, and a fixed display change period is determined. This register DT counts
In the step 15 of changing the display when overflow occurs, the display contents of only the digits that have not yet been stopped, that is, the digits for which the flags S1 to S4 are not set, are changed as a preprocess for changing the display. This change is made in register X. Step 16 displays the contents of register X and changes the displayed contents of the game. In step 17, when the game operation is finished as determined in step 12, it is determined whether there is a matching digit, that is, whether flags 1P to 4P are set. In step 18, when flags 1P to 4P are set, only the matching digits are turned on and off by about 1/2
Repeats twice every second to indicate a match. A specific example of blinking according to the matched digits is shown in FIG. Figure a has only two digits (“3” and “3” in this case)
indicates a match, and the two-digit number flashes repeatedly. Figure b shows the case where two sets of two digits match,
At this time, one matching digit flashes first, and then the other matching digit flashes. Furthermore, Figure c shows the case where all four digits match. Step 19 automatically calculates the score after the processing of step 18 is completed. In step 20, when the display change of all digits is stopped, it is determined whether the display contents and order of the four digits are a certain specific display contents (pattern). At step 21, a score display similar to that at step 18 is performed. In this case, all the digits will blink as in FIG. 5d, but the blinking will be repeated until the next key operation. In step 22, when the display contents of the 4 digits are blinking in a specific display content (pattern), a key (specific key) is pressed to stop the display content of each digit mentioned above in a specific display state. Determine whether or not it has been operated. In step 23, when a specific key is operated as determined in step 22, display data (this may be called secret data) that cannot be obtained through normal operation is set in register X. Step 24 displays the contents of register X. Note that steps 21 to 23 are similar to steps 18 and 1.
Similarly to 9, secret data may be automatically set in register X after the blinking process. In this case, step 2
The key determination in step 2 is no longer necessary. FIG. 6 shows an example of displaying the secret data.
When the random display change of 4 digits is stopped and the content (first symbol) matches the specific display content pattern (second symbol) stored inside the CPU, the results shown in Figure 6 e and f are shown. All digits flash repeatedly. When a certain key is operated, the 6th
Secret data (specific symbols) as illustrated in Figure g are displayed. This secret data cannot be obtained in any other state or in any other operation. Now, returning to FIG. 4 again, the score calculation in step 19 is executed using the following equation. A×B+C×T Here, A is the score based on the number of matched digits, 20 points for a 4-digit match, 15 points for a 3-digit match, and 2 points for a 2-digit match.
If the pair matches, 5 points will be given, if two digits match, 2 points will be given, and if there is no match at all, 0 points will be given. B is a score based on the contents of the matched digits. If the matched contents are numbers from 0 to 9, it is 8 points, and when it is other letters, it is 8 points.
It will be worth 10 points. C is a constant, and T is a time element of the game, which is the time obtained by subtracting the time required to stop all four digits from the preset game time. As explained above, according to the present invention, symbols that change randomly or at a predetermined period are displayed on a plurality of digits of the display, and by stopping the symbol display by key operation, the stopped symbol is displayed. You can play a game using the match or mismatch between a signal and a signal representing a predetermined symbol, and in the game mode, for all digits where symbols are displayed, the symbol when stopped matches a specific display content. After the all-digit symbol at the time of stop changes to a specific display content, by operating a specific key, confidential data that you do not want a third party to know will be displayed on the display. Since the game mode is configured so that the game mode is displayed as a secret data calling mode, the risk of the secret data being discovered by another person can be reduced.
