2. Description of the Related Art Conventionally, in a ball-and-ball game machine such as a pachinko machine, when a game ball is fired by a shooting means to a game area of a game board and a game ball falling along the game board wins a symbol starting means. In the symbol display means provided substantially at the center of the game board, for example, the symbols displayed on the three symbol display units are started to fluctuate, and a lottery for extracting one from a plurality of lottery values is performed. Then, a "big hit" or a "loss" is determined based on the lottery result. When the lottery result is "big hit", after changing the symbol of each symbol display unit for a predetermined time, it is stopped at a big hit symbol such as "777", and when "losing", after changing the predetermined time, for example, " 643 "or the like.

When stopping at the display of the big hit symbol,
In the special game state, by satisfying a predetermined condition in the special game state, the openable prize means is intermittently opened and closed up to 16 times at maximum, so that it is easy to win a game ball in the openable prize means. And return a great deal of profits to the player. Here, the main control means, which controls the game operation relating to the game board, repeats the main game program of the game control every predetermined minute time (for example, about 2 msec),
The game operation is executed.

The lottery means for selecting a lottery numerical value sets a lottery numerical value of a jackpot lottery counter at about every 2 msec update cycle, with an update cycle of about 2 msec at which the main game program is periodically executed. By updating while counting one by one, for example, from among 300 ring-shaped numerical value groups including a numerical value range from “0” to “299”,
One is selected at each update cycle to update the lottery value. Then, for example, when the game ball is won in the symbol starting means, it is set to a specific numerical value that hits “7”,
Since the lottery means extracts the lottery value of the jackpot lottery counter, the determination means determines whether the value is "big hit" or "losing".

That is, one of a plurality of lottery values generated at regular intervals of about 2 msec is randomly selected at an irregular prize timing when a prize is awarded to the symbol starting means. This makes it possible to set equal and fair jackpot probabilities for all players, enhance the playability of the players, enliven the ball game, and at the game store side Profit can be secured.

[0006]

In the conventional ball game machine, as described above, a value when a symbol is won at an irregular winning timing to the symbol starting means is generated as a random number as a result and the lottery is performed. Therefore, an equal and fair jackpot probability is set for each player, but a player having the technical ability for the gaming machine is required to set the jackpot cycle of the jackpot lottery counter, that is, the A plurality of lottery values to be updated read a cycle period from the leading value to the trailing value, and game balls are regularly won at a periodic timing at which a particular value to be a big hit is drawn. In addition, the jackpot probability is dramatically improved, and a great profit is obtained.

As one of the techniques, there is a technique in which a jackpot is intensively drawn by a bodily sensation capture method. This bodily sensation capture method is to set a cycle similar to the jackpot cycle in which jackpots are drawn to a device called a bodily sensation such as a rhythm counter, and to set the cycle in which the jackpot occurs due to the periodic vibration of this bodily sensation The firing timing of the game ball is adjusted so that the player can experience the game and win the symbol starting means at the timing of the big hit. As described above, limited to a specific player having a special game technique, a lot of profits can be obtained by intensively drawing jackpots using various techniques. Side suffers a great deal of loss.

[0008] In particular, at present, it is impossible to effectively prevent acts that cause intensive hits due to illegal remodeling, which is illegal. An object of the present invention is to make it possible to randomly generate a winning timing at the time of a lottery, to make the probability of a big hit fair for any player, and to be able to cope with a big hit shooting. And to ensure the profitability of the store.

The 2 msec signal generating means 66 divides the frequency of the clock pulse supplied from the clock generator 54 to generate a signal every 2 msec. When the 2 msec signal is received during execution of a main game program 52a to be described later, the main control is repeatedly executed from the top address in synchronization with the 2msec signal. Next, the main control means 6
The game control executed by 0 will be described with reference to the flowchart of FIG. However, the symbol Si (i
= 1, 2, 3...) Are steps. When power is supplied to the pachinko machine 2 at the start of business and this game control is executed, control by the main control means 60 is started.

When the game control is started, first, various initial settings of the CPU 51 of the microcomputer 50 are executed (S1). Thus, actual game control is started. Next, when power is supplied by operating a power switch (not shown) based on the data written at the specific address (S2: Yes), an erasing process for erasing data in the RAM 53 of the microcomputer 50 is performed. (S3) Various initial value setting processes such as setting an initial symbol to be displayed on the symbol display means 22 and setting a control cycle for repeatedly executing the main game program to "2 msec" are executed (S4). ).

Thereafter, in the remaining time until a predetermined control cycle (about 2 msec) is reached, a symbol data change process (S5) for determining the next symbol by updating, and a numeric value for updating a dummy numeric value not related to the game. The update process (S6) is repeatedly executed. In this way, about 2
The processing time is adjusted by repeatedly executing S5 and S6 for the remaining time until elapse of msec. By the way, S
After about 2 msec elapses during execution of steps 5 to S6, a 2 msec interrupt signal (corresponding to a reset signal) is supplied from the 2 msec signal generation means 66 to the CPU 51 of the microcomputer 50 as an internal interrupt.

As a result, for example, a restart instruction (RST instruction) due to an internal interrupt is executed, the processing time adjustment control in S5 and S6 is forcibly stopped halfway, and the program jumps to the top of the main game program. The main game program (S7 to S16) is repeatedly executed.
Next, the main game program will be described.
First, a drive signal output process of outputting a drive signal to a solenoid for driving the opening / closing claw 17a of the symbol starting means 17 and the opening / closing plate 18a of the opening / closing winning means 18 is executed (S7).

Next, a switch signal input process for reading switch signals from various switches including a winning detection sensor provided in each of the winning means 17 to 19 is executed (S8).
Next, a lottery numerical value update process for incrementing the second lottery numerical value of the second count memory included in the RAM 53 by one is executed (S9). Next, an output process of outputting a payout control command to the payout control means 77 is executed (S
Ten). Next, an output process of outputting a sound control command to the sound control means 76 is executed (S11). Furthermore,
An output process for outputting a lamp control command to the lamp control means 75 is executed (S12).

Next, a process relating to the ordinary symbol for causing the ordinary symbol to be variably displayed on the ordinary symbol display section of the second symbol display means 23 is executed (S13). Next, processing relating to the special symbol, such as outputting a symbol control command for causing the special symbol display means 22 to variably display the special symbol, is executed (S14). Next, when the opening / closing pawl 17a of the symbol starting means 17 is driven, an operation command output process for outputting a command for instructing the operation is executed (S15). When driving the opening / closing plate 18a of the open / close winning mechanism 18, an operation command output process of outputting a command for instructing the operation is executed (S16).

At this time, if about 2 msec has not elapsed since the execution of the main game program, the control time is adjusted by repeatedly executing S5 and S6 as described above. However, during execution of S5 and S6, 2
When msec elapses and the CPU 51 is internally interrupted by a 2 msec interrupt signal, the game control is restarted each time, and the main game program after S7 is repeatedly executed. Here, as shown in FIG. 10, as described above, the first lottery value of the first count memory is about 0.78 msec.
Since it is updated by incrementing by one every time, "0
Up to 299 "are updated in a cycle of about 0.235 seconds.

On the other hand, the second lottery numerical value of the second count memory is updated by incrementing by one every about 2 msec, so that 300 numerical values from "0 to 299" are reduced by about 0.6.
The update process is performed in one second. Therefore, when the first lottery value matches the second lottery value, the first lottery value (191) in the second round matches the second lottery value (191) in the first round, The first lottery value (83) in the fourth round matches the second lottery value (83) in the second round, and the first lottery value (275) in the fifth round and the second lottery in the second round The values (275) and (191) match, and similarly, the values match (59), (250), (142), and so on. In addition, the timing at which the first lottery value and the second lottery value match occur irregularly.
