Description

[Detailed description of the invention]

The present invention relates to a novel random number generation device that can appropriately generate random numbers within the range of a number arbitrarily designated by a key means as the maximum value. Conventional random number generators have a limited range of use because the maximum value of random numbers to be generated is fixed in advance. Furthermore, although it is possible to change the maximum value with a programmable function, it is almost impossible to put it to practical use because it requires complicated programming procedures. Therefore, an object of the present invention is to provide a versatile random number generator that can easily change the maximum value of random numbers and is not limited in its range of use. Another object of the present invention is to provide a random number generation device that adds a gaming aspect to the random number display by making the random number display even easier to see. Another object of the present invention is to provide a random number generator with excellent operability. An embodiment of the apparatus of the present invention will be described in detail below based on the drawings. FIG. 1 shows an example in which the device of the present invention is mounted on an electronic desktop calculator. In the figure, 1 is the central processing unit (CPU), 2 is the read-only memory (ROM), and 3 is the central processing unit (CPU).
is the read/write memory (RAM), 4 is the 0 to 9 numeric keys necessary for calculation, the function key, the on clear key ON/C, and the random number generation key.
Keyboard with RND, 5 is display buffer,
6 is a display body. The CPU 1 performs controls such as reading keys or displaying the contents of the ROM 3 on the display 6 according to a procedure written in the ROM 2 in advance. The ROM 2 stores procedures for reading and displaying keys and procedures for performing calculations and other operations according to numerical values and formulas written in the RAM 3. On the other hand, the RAM 3 is a memory that stores numerical values and formulas, and also stores various condition flags and counters used in the processing process of the CPU 1. Figure 2 shows a part of the RAM used in the device of the present invention. In particular, it shows a register X that stores calculation results and generated random numbers, and a register It is provided with a register MAX which stores the maximum possible number and usually stores the number "6" as the maximum number. S is a strobe signal from the CPU1, and K is a key signal output from the keyboard KEY4. The display body 6 has a random number display area in addition to the display area for calculation results. This random number display area is configured to be able to display dice (two dice can be displayed at the same time) and coins, which will be described later. That is, Fig. 3 is an example of a display when the maximum possible random number set using the number key is "3" or more, and in this case, one or two dice of a to i are displayed. Become. On the other hand, Fig. 4 shows an example of the display when the set number is "2", that is, there are two results, "1" or "2". In this case, the trajectory 7 when the coin is thrown is shown.
The coin is displayed with a white circle (front side) 8 or a black circle (back side) 9 indicating the result. The track 7 is displayed as if a coin had been thrown by lighting up each divided segment in turn as shown in Figure 5 l to p, and after the display of this track is completed, the table ( The screen is configured so that the back (white circle) or the back (black circle) is displayed. Next, key operations when displaying random numbers will be described. First, when setting the maximum possible random number to "3" or more, for example,

Press the keys in the order of [expression]. Ru. In this case, the first

By operating the [Formula] key, the contents of the two dice in the dice display area are randomly changed and displayed, and this is the start of random number display. And the second time

[Formula] After a while after the key operation, the display contents stop, and in this case, two random numbers from 1 to 9 are displayed simultaneously in the two dice display areas. Also, if you want to set the maximum possible random number to "2",

Operate the keys in the order of [expression]. In this case, the coins will be displayed as j or k in FIG. Additionally, if you do not specify the maximum number above,

Operate the keys as shown in [Formula]. In this case, the maximum possible random number is automatically set to "6", and random numbers from 1 to 6 are displayed on the dice. Note that even when the maximum possible random number is "0" or "1", the maximum number that can be taken as a random number is automatically set to "6" as described above. FIG. 6 shows a flowchart, and the operation will now be explained in more detail with reference to this diagram. First, in _J1 , it is determined whether or not a numerical value has been input into the calculator immediately before random number generation is executed, and if it has been input, the process moves to _J2 and checks whether the numerical value is "3" or more. Make a judgment.
If the result of the determination is negative, the process further advances to _J3 to determine whether the input numerical value is equal to "2" or not. Here, if the input numerical value is equal to "2", the process enters the coin display flow surrounded by the dotted line A. That is, first, in step _A1 , the trajectory of the coin is displayed (see FIG. 5, l to p). Then, when you confirm the completion of the track display using _J4 , the step
Proceeding to step _A2 , a random number is generated in the register X of the read/write memory RAM 3 to determine whether the coin is front or back, and the coin is displayed as shown in FIG. 4j or k in step _A3 . On the other hand, if the result of the judgment in _J1 is that the number has not been specified yet, or if the specified number is 0 or 1 as a result of the judgment in _J2 and _J3 , the step of the dice display flow is executed.
Proceed to A ₄ and read/write memory RAM3.
The preset value 6 is stored in the register MAX, and from then on, random numbers from 1 to 6 are displayed. Furthermore, as a result of the judgment of _J2 , the number is 3.
In the above case, the process moves to step _A5 of the dice display flow similar to the above, and in this case, the set number is stored as it is in the register MAX of the RAM 3. In this way, when a value of "3" or more is stored in the register MAX, the first RND key operation advances to step _A6 , and a random number is stored in the register X within the range of the value stored in the register MAX. to occur. Then, in step _A7 , a random number is randomly displayed on the dice in relation to the random number generation in the register
By key operation, the display contents are stopped at an appropriate point and a random number dice is displayed.
_J5 ). In this way, you can specify the maximum number of random numbers, obtain random numbers within the range, and display symbols such as dice or coins, or automatically when you do not specify a number. It is possible to generate random numbers within a predetermined number range. It should be noted that the determination of the end of the arrow _J5 may be made by rotation as in the case of coin display, or may be made in conjunction with a key operation from outside the computer. As explained above in detail, according to the device of the present invention, the maximum value of the random number can be changed extremely easily with a simple key operation, and since the random number is displayed as a symbol, it is possible to add a game effect. At the same time, the display becomes easier to see. Furthermore, random number generation is usually performed automatically within a preset number range, so
If you decide the number of settings according to the frequency of use,
It is possible to achieve excellent effects not found in conventional random number generators, such as significantly improving operability.
