2. Description of the Related Art A conventional game machine will be described with reference to FIGS. 10 to 13 by taking a pachinko machine as an example. Figure 10
[Fig. 4] is a front explanatory view showing a main configuration of a conventional pachinko machine. 11 (A) is an explanatory diagram showing an arrangement relationship between the first-type starting port and the first-type starting port switch provided in the pachinko machine shown in FIG. 10, and FIG. 11 (B) is shown in FIG. It is explanatory drawing which shows a part of electrical structure of the pachinko machine shown in a block. FIG. 12 is an explanatory diagram showing an example of a circuit in which an illegal act has been performed. FIG. 13 (A) is an explanatory diagram showing a conventional arrangement of jackpot values, and FIG. 13 (B) is an explanatory diagram showing a timing for acquiring a count value when an illegal RAM clear instruction is issued.

As shown in FIG. 13 (A), in a conventional pachinko machine, a jackpot lottery counter used for lottery for a big hit or a lost hit counts a total of 953 numbers from 0 to 952. Out of 953, "7" and "277"
And a total of three count values of "293" are set to the jackpot value. That is, a big hit occurs when the count value acquired from the big hit lottery counter is the big hit value. The probability of a big hit is 3/953 = about 1/318
Is. An upward arrow in the drawing indicates the timing when the main CPU 531 (FIG. 11B) acquires the count value of the jackpot lottery counter. In FIG. 10, when a game ball that is fired by operating the operation handle 501 provided on the pachinko machine 500 wins the first-class starting opening 502 or the ordinary electric accessory 503 with both wings open, the winning ball is , The first-type starting port switch 510 (FIG. 11B). At the timing of this detection, the main CPU 5
31 obtains one count value of the jackpot lottery counter, and lottery whether it is a jackpot or a loss based on whether or not the obtained count value is a jackpot value. Further, at the above detection timing, a plurality of symbols (for example, 0 to 9) are scroll-displayed in the vertical direction at three horizontal positions on the screen of the symbol display device 504, and a symbol corresponding to the lottery result after a predetermined time elapses. Confirmed display. For example, if the lottery result is a big hit, three identical numbers (for example, “777” as shown in FIG. 10) are confirmed and displayed,
The door-type opening / closing member 505 is opened, and the special winning opening 506 is opened.

When a game ball is won in the special winning opening 506, a predetermined number (for example, 15) is attached to each winning ball.
The individual prize balls are paid out to the upper tray 507. In addition, the number of winning balls that have won the special winning opening 506 is a predetermined number (for example,
10), or a predetermined time (for example, 30 seconds) has passed since the special winning opening 506 was opened, or if any of the conditions is satisfied, the opening / closing member 505 is closed and the big winning opening is performed. 506 closes. Furthermore, the big prize hole 50
When the game ball winning 6 wins the specific area 508 provided inside the special winning opening 506, the right to continuously open the special winning opening 506 is generated. In this way, the big prize hole 5
It is possible to play a plurality of rounds (for example, 15 rounds) on the condition that the opening from 06 to the closing of 06 is one round, and the game ball passes through the specific area 508.

Further, as shown in FIG. 11B, the pachinko machine 500 is provided with a power failure detection circuit 516 for detecting a power failure, and the power failure detection circuit 516 is provided in the main board 5.
30 and the payout control board 540. The main CPU 531 mounted on the main board 530 acquires the count value of the jackpot lottery counter as described above, performs a lottery of whether it is a jackpot or a loss, or controls a round. A computer program executed by the main CPU 531 is recorded in the ROM 533, and a RAM is stored in the RAM 533.
532 stores a game state when the power is cut off, a computer program read from the ROM 533, a control command transmitted from the main CPU 531 to each board, and the like. The sub CPU 541 mounted on the payout control board 540 controls a prize ball payout motor (not shown) in accordance with the prize ball payout command transmitted from the main board 530. A computer program executed by the sub CPU 541 is recorded in the ROM 543, and the RAM 542 stores the number of unpaid prize balls when the power is cut off, the computer program read from the ROM 543, and the like.

Here, when the power supply 520 is cut off, a power cutoff signal is output from the power failure detection circuit 516 to the main board 530 and the payout control board 540, and the main CPU 531 and the payout control board 540 mounted on the main board 530 are provided. The mounted sub CPUs 541 each execute NMI (non-maskable interrupt) processing, and RAMs 532, 5 storing backup data at the time of power-off.
Access to each backup area 42 is prohibited. Further, power is supplied to each backup area from the backup capacitor C2, and the storage of each backup data is held. Then, when the power supply 520 returns, the main CPU 531 reproduces the game immediately before the power shutdown based on the backup data stored and held in the backup area of the RAM 532. In addition, the sub CPU 5
41 restarts the payout of prize balls based on the number of unpaid prize balls stored and held in the backup area of the RAM 542.

However, if the power is cut off during the test firing during the shipment of the pachinko machine or the installation of the pachinko machine,
Data about big hits and winnings that occurred during trial shooting are R
Since it is backed up by AM, opening the store in that state causes inconvenience such as starting a game based on the backed up data. So RAM
There has been proposed a method for eliminating the above inconvenience by providing a RAM clear switch 527 for outputting a RAM clear signal for erasing backup data to each RAM.

[0008]

By the way, as a result of subsequent research, when the RAM clear switch 527 is turned on,
It was found that resetting the initial value of the jackpot lottery counter to "0" could be misused. Figure 1
As shown in FIG. 2, an unauthorized board 550 called a hanging board is connected to the line connecting the RAM clear switch 527 and the main board 530. The hanging board 550 is equipped with a circuit that sends a RAM clear signal to the main board 530 when a command sent from the transmitter 560 is received. If the count cycle of the jackpot lottery counter is 2 ms, the time required to start counting from "0" and count the jackpot value "7" is 2 ms x 7 = 14 ms. In addition, FIG.
As shown in (A), the time required for the game ball P to be detected by the first type starting port switch 510 after passing through the first type starting port 502, that is, from the first type starting port 502 to the first type. It is assumed that the time required to flow down the distance L1 to the starting port switch 27a is 0.4 s.

Then, when the above command is transmitted from the transmitter 560 to the hanging board 550 0.386 seconds after the game ball P passes through the first type starting opening 502, the hanging board 5
A RAM clear signal is transmitted from 50 to the main board 530,
The initial value of the count of the jackpot lottery counter is reset to "0", and the counting is started from "0". And
When the game ball P is detected by the first type starting opening switch 510 14 ms (= 0.4 s−0.386 s) after that, the jackpot lottery counter then counts “7”. Therefore, when the above command is transmitted from the transmitter 560 to the hanging board 550 aiming at the timing 0.386 s after the game ball P passes through the first type starting opening 502, as shown in FIG. 13 (B), The count value acquisition timing is concentrated in a narrow range including the big hit value "7". In other words, the main CPU 531 acquires the count value from the jackpot lottery counter that counts the vicinity of the jackpot value of "7", and the chance of a jackpot is extremely high.

Therefore, the present invention has been made in order to solve the above problem, and it is possible to illegally generate a big hit by giving an instruction to erase the stored game state when the power is cut off. The purpose is to realize a gaming machine that cannot.

[0011]

Means, Actions and Effects for Solving the Problems In order to achieve the above object, the present invention provides a counter and a game ball shot on a game board which passes through a predetermined area. Detection means for detecting that, a game state storage means for storing the game state when the power supplied to this gaming machine is cut off, and the game ball has passed the predetermined area by the detection means When the count value of the counter is detected when it is detected, lottery means for lottery based on the acquired count value whether it is a big hit or a loss, and a value when the counter starts counting is set to an initial value. It is provided with erasing means for returning and erasing the game state stored in the game state storing means, and is stored in the game state storing means when the power supply is restarted. A gaming machine capable of resuming a game based on a gaming state in which the counter takes time to count from the initial value to a count value targeted for a big hit by the lottery means, A technical means is used in which the time is set to be longer than the time required for the gaming ball to be detected by the detecting means after passing through the predetermined area.

The lottery means acquires the count value of the counter when the detecting means detects that the game ball has passed through the predetermined area, and determines whether the jackpot or the big hit is based on the acquired count value. Lottery. Also,
The erasing means resets the value when the counter starts counting to the initial value and erases the game state stored in the game state storage means. Then, the time required for the counter to count from the initial value to the count value that is targeted for the big hit and the lottery by the lottery means is from when the game ball passes through the predetermined area to when it is detected by the detection means. It is set longer than the time required for. That is, when the erasing instruction is given when the game ball passes through the predetermined area, the value when the counter starts counting returns to the initial value, and the counter starts counting from the initial value. However, the time required for the counter to count from the initial value to the jackpot count value is set to be longer than the time required from when the game ball passes through the predetermined area to when it is detected by the detection means. Therefore, since the counter does not count the big hit value when the game ball is detected by the detecting means, there is no possibility that the big hit will occur. Therefore, it is possible to prevent the occurrence of a big hit due to an illegal deletion instruction.

According to a second aspect of the invention, in the gaming machine according to the first aspect, the counter starts counting from the initial value when the game ball passes through the predetermined area, and the predetermined value. When the game sphere that has passed through the area is ended by the detection means, when the count is finished, during the period from the start to the end of the counter, the count value that is a big hit and is selected by the lottery means. The technical means of not counting even one is used.

That is, even if the erase instruction is illegally issued when the game ball passes through the predetermined area and the counting is started from the initial value when the counter starts counting, the predetermined value is set. When the game sphere that has passed through the area is detected by the detecting means, the counter has not yet counted the big hit and the count value to be drawn by the lottery means, so there is no possibility of a big hit.

According to a third aspect of the invention, a counter and
Detecting means for detecting that a game ball shot on a game board has passed a predetermined area; game state storing means for storing a game state when power supplied to this game machine is cut off; A lottery means for obtaining a count value of the counter when it is detected that the game ball has passed through the predetermined area by a detecting means, and a lottery for lottery or losing based on the obtained count value, The counter has a value when the counter starts counting and returns to an initial value, and an erasing means for erasing the game state stored in the game state storing means is provided, and when the power supply is restarted. A game that can be restarted based on the game state stored in the game state storage means, and the counter is a jackpot selected by the lottery means from the initial value. The time required to count up to the count value becomes longer than the time required from the time the game ball passes through the predetermined area to being detected by the detection means by the computer. It is a computer program for operating, the time required for the counter to count from the initial value to a count value that is targeted for a big hit by the lottery means, the game ball is in the predetermined area. A technical means called a computer program is used which is set to a time longer than the time required from when the vehicle passes through to the time when it is detected by the detecting means.

That is, since the gaming machine according to claim 1 functions by a CPU (computer) provided in a pachinko machine (gaming machine), for example, as described in an embodiment of the invention described later, By storing the computer program in a recording medium such as a ROM and causing the CPU to execute the stored computer program, the gaming machine can be caused to function.

According to the invention described in claim 4, a counter,
Detecting means for detecting that a game ball shot on a game board has passed a predetermined area; game state storing means for storing a game state when power supplied to this game machine is cut off; A lottery means for obtaining a count value of the counter when it is detected that the game ball has passed through the predetermined area by a detecting means, and a lottery for lottery or losing based on the obtained count value, The counter has a value when the counter starts counting and returns to an initial value, and an erasing means for erasing the game state stored in the game state storing means is provided, and when the power supply is restarted. A game that can be restarted based on the game state stored in the game state storage means, and the counter is a jackpot selected by the lottery means from the initial value. The time required to count up to the count value becomes longer than the time required from the time the game ball passes through the predetermined area to being detected by the detection means by the computer. A recording medium in which a computer program for functioning is recorded, wherein the counter has a time required to count from the initial value to a count value targeted for a big hit and lottery by the lottery means,

"847", "907", "937" and "947"
15 in total are set as big hit values in the big hit value table. That is, no big hit value is set between the count values "0" to "316". In other words, 2 ms × 317 = 634 ms = 0.6 after the jackpot lottery counter Ct1 starts counting from “0”.
It is set so that the jackpot value is not counted during 34 s.

In this way, the jackpot lottery counter Ct1
The time required to count the first jackpot value "317" when the counting starts from "0" is detected by the first-class starting opening switch 27a from the timing when the game ball passes through the first-class starting opening 27. It is set to be sufficiently longer than 0.4 s, which is the time to reach the timing. Therefore, the player performing the fraudulent activity will receive R from the transmitter 0.386 s after the game ball passes through the first type starting opening 27.
The instruction to clear the AM is issued and the jackpot lottery counter Ct1
Even when the count is started from "0", when the game ball is detected by the first type starting opening switch 27a, the jackpot lottery counter Ct1 still has the count value of 7
Since (= (0.4s-0.386s) / 2ms) is being counted, there is no possibility that the big hit value "317" is counted and a big hit occurs. Also,
Even when a player who conducts an illegal act gives an instruction to clear the RAM at the same time when the game ball passes through the first type starting opening 27, the jackpot lottery counter Ct1 still has a count value of 200 (= 0. 4s / 2ms), and between "200" and "317",
2ms × (317-200) = 234ms = about 0.2s
Because there is an interval of and there is a margin, the jackpot value "317"
There is no danger that a big hit will be generated by counting.

(RAM clear processing) Main CPU 112
Performs a security check to check whether the computer program recorded in the ROM 114 has an abnormality (step (hereinafter abbreviated as S) in FIG. 7) 1
0), the work area of the RAM 116 is initialized (S1)
2). Subsequently, the main CPU 112 determines whether or not the RAM clear switch 10 (FIGS. 4 and 6) is pressed and turned on (S14). If it is determined that it is ON (S14: Yes), the RAM clearing process is executed (S18). That is, the backup data stored in the RAM 116 is erased, and the value when the jackpot lottery counter Ct1 starts counting is returned to the initial value “0”. As described above, the RAM clear process is also executed when a signal is transmitted from the transmitter 560 to the hanging board 550 and a signal is transmitted from the hanging board 550 to the main board 100 due to an illegal act. Then, the main CPU 112 starts game control such as detection of winning, lottery for big hit or loss, updating of initial value of big hit lottery counter Ct1 (S20). Further, the main CPU 112 uses the RAM clear switch 10
If is not turned on (S14: No), RAM11
It is determined whether the check data stored in 6 is correct data, for example, A5A5H (S16). If it is A5A5H (S16:
Yes), start controlling the game (S20), A5A5H
If not (S16: No), it is determined that abnormal data is stored in the RAM 116, and RAM clear processing is executed (S18). The RAM clearing process is executed according to a computer program recorded in the ROM 114.

(First-Type Starting Port Process) When the first-type starting port switch 27a (FIG. 3) is turned on, the main CPU 112 is activated.
Determines that the first type starting port switch 27a is turned on by detecting the voltage change of the input port connected to the first type starting port switch 27a (S30: Y in FIG. 8).
es), it is determined whether or not the special symbol starting memory number U1 is less than "4" (S32), and if it is less than "4" (S)
32: Yes), "1" is added to the special symbol starting memory number U1 (S34). Subsequently, the main CPU 112 acquires one count value counted by the jackpot lottery counter Ct1 (FIG. 5) (S36), and temporarily stores the acquired count value in the RAM 116 (S38). Here, due to the above-mentioned fraudulent acts, the game ball is the first type starting opening 2
When the RAM clear instruction is issued when passing 7, the big hit lottery counter Ct1 starts counting from "0", and the game ball is detected by the first type starting opening switch 27a. The count value when
As shown in (B), since it is around 200, 20
The count value around 0 is acquired and stored in the RAM 116. In addition, the above-mentioned first type starting port process is performed by R
It is executed by the computer program recorded in the OM 114.

(Special symbol control) The main CPU 112,
It is determined whether or not a control command for controlling the symbol control device 32 is output to the symbol control device 32, that is, whether or not the special symbol is changing (S50 in FIG. 9), and it is determined that it is not changing. Then, (S50: No), it is determined whether or not the special symbol starting memory number U1 is "1" or more (S5).
2). Here, if the main CPU 112 determines that the special symbol starting memory number U1 is “1” or more (S52: Ye
s), "1" is subtracted from the special symbol starting memory number U1 (S
54), the count value temporarily stored in the RAM 116 in S38 (FIG. 8) of the above-described first type starting opening processing is read (S56). Subsequently, the main CPU 112 determines whether or not the probability variation flag indicating that the game state is probability variation is set (probability variation flag = 1 or 0) (S
58). Here, when the main CPU 112 determines that the probability variation flag is set (S58: Yes),
Referring to the big hit value table at the time of high probability (S60), S5
Whether or not it is a big hit is determined based on whether or not the same big hit value as the count value read in 6 is set (S6).
4). For example, the count value read in S56 is "34.
If it is "7", it is determined as a big hit (S64: Ye
s).

If the probability variation flag is not set (S58: No), the big hit value table at the time of normal probability is referred to (S62), and whether the same big hit value as the count value read in S56 is set. Based on whether or not it is a big hit, it is determined (S64). For example, when the count value read in S56 is "317", it is determined that it is a big hit (S64: Yes). By the way, no big hit value is set between the count values “0” to “316”. Therefore, as described above, when the gaming ball passes through the first-class starting opening 27 due to a fraudulent act, RA
When the M clear instruction is given, the count value of around 200 is stored in the RAM 116, so that it is not judged as a big hit. Then, the main CPU 112
When it is determined to be a big hit (S64: Yes), a big hit flag indicating that a big hit has occurred is set (S6).
6), referring to the big hit design table which decides the big hit design, the big hit design is decided (S68), it decides whether or not the selected big hit design is the probability variation design (S70).
Here, the probability variation symbol means a specific symbol (for example, an odd number of jackpot symbols) among the jackpot symbols, and if the probability variation symbol is a jackpot, the game after the game of the jackpot is over, Change suddenly.

Here, if it is a probability variation pattern (S70:
Yes), and the probability variation flag is set (S72). Further, the main CPU112 is not a big hit, that is, when it is determined that the lost design (S64: No), refer to the lost design table for determining the lost design, the lost design to be fixedly displayed as the left design, the middle design and the right design, respectively. It is determined (S74). In addition, the jackpot symbol table, a plurality of random numbers (for example, 0-9) and a plurality of special symbols (for example,
000 to 999) are associated with each other, and the special symbol associated with the random number randomly selected by the main CPU 112 is determined as the big hit symbol. The lost symbol table is configured by associating a plurality of random numbers (for example, 0 to 9) with a plurality of special symbols (for example, 0 to 9), and corresponds to a random number randomly selected by the main CPU 112. The special design attached is determined as the lost design. If the determined lost design is the same as the jackpot design, the lost design is determined again. The lost symbols are determined for the left symbol, the middle symbol and the right symbol respectively, and a total of three lost symbols are determined. Subsequently, the main CPU 112 determines the variation pattern of the special symbol by referring to the variation pattern table that determines the variation pattern of the special symbol (S76). The variation pattern includes a variation time of the special symbol, a type of reach when the reach is performed, a normal stop pattern when the reach is not performed, and the like.
Subsequently, the main CPU 112 transmits a variation start command indicating the variation pattern determined in S76, the big hit symbol determined in S68 or the lost symbol determined in S74 to the symbol control device 32 (S78). Subsequently, the main CPU 112 starts measuring the variation time of the special symbol indicated by the variation pattern determined in S76 (S80).

Further, the main CPU 112 transmits the variation pattern designation command to the symbol control device 32, and at the same time, transmits the variation pattern designation command to the voice control device 79 and the lamp control device 300 (FIG. 3). As a result, the voice control device 79 outputs the sound effect in the pattern corresponding to the received fluctuation pattern designation command, and the lamp control device 300 lights various LEDs in the pattern corresponding to the received fluctuation pattern designation command. Let Then, the main CPU 112 determines in S80 that the time when the measurement is started is up (S82: Yes).
s), an all symbol stop command for instructing the stop of all symbols is transmitted to the symbol control device 32 (S84), and the measurement time is reset (S86). Thereby, the symbol display 32a is
The jackpot or lost design is confirmed and displayed. Also,
The voice control device 79 stops the output of the sound effect, and the lamp control device 300 stops the lighting of the LED. The special symbol control is executed according to a computer program recorded in the ROM 114.

[Effects of the Embodiment] As described above, when the pachinko machine 1 of the above embodiment is used, the time required for the jackpot lottery counter Ct1 to count from the initial value to the jackpot value is the gaming ball Since it is set to be longer than the time required to be detected by the first type starting port switch 27a after passing through the first type starting port 27, the jackpot lottery is performed at the timing when the game ball passes through the first type starting port 27. Even if the counter Ct1 for counting starts from "0", the jackpot lottery counter Ct after the game ball is detected by the first type starting opening switch 27a.
1 will count the jackpot value. Therefore,
A player who conducts cheating conducts R by the transmitter 0.386 s after the time when the game ball passes through the first type starting opening 27.
When the AM clear instruction is given, the jackpot lottery counter Ct1
Starts counting from "0", and when the game ball is detected by the first type starting opening switch 27a, it means that "7" is counted. In other words, the first big hit value “317” is never acquired, so there is no risk of a big hit occurring. In addition, even when the player who conducts the cheating gives the instruction to clear the RAM at the same time when the game ball passes through the first type starting opening 27, the jackpot lottery counter Ct1 still has a count value of 200 (=
0.4s / 2ms) is being counted,
Between "200" and "317", 2ms x (3
17-200) = 234 ms = about 0.2 s exists and there is a margin, so there is no possibility that the big hit value “317” is counted and a big hit occurs.

<Other Embodiments> (1) The big hit lottery counter Ct1 starts counting from "0", and the time required to count the first big hit value is the first kind start opening 27 of the game ball. As long as it is sufficiently longer than the time from the timing of passing through to the timing of being detected by the first type starting opening switch 27a, the arrangement of the jackpot value is not limited to that described in the above embodiment, and the game ball is the first. The time can be changed as appropriate according to the time from the timing of passing through the type 1 starting port 27 to the timing detected by the type 1 starting port switch 27a. (2) Also, the jackpot value is the jackpot lottery counter Ct1.
It can be changed according to the count cycle of. For example, when the count cycle of the lottery counter Ct1 is 1 ms, 0 to 400 (= 0.4 s / 1 for 0.4 s).
ms) will be counted, so the jackpot value will be "4
Set to a value larger than "00" (for example, 607). If set in this way, the game ball is the first type starting opening 27.
Even if the RAM clear instruction is illegally issued at the same time when the game ball is passed, when the game ball is detected by the first type starting opening switch 27a after 0.4 seconds, the jackpot lottery counter Ct1 is still on. Since "400" is being counted, there is no possibility of an illegal big hit.

(3) Furthermore, the big hit value is the game ball first.
It can be changed according to the time required from the seed starting port 27 to the first type starting port switch 27a. For example, the time required for the game ball to reach the first type starting port switch 27a from the first type starting port 27 is 0.2 s, and the count cycle of the jackpot lottery counter Ct1 is 2 m.
When it is s, the jackpot lottery counter Ct1 indicates 0.
Since 0 to 100 (= 0.2 s / 2 ms) is counted during 2 s, the jackpot value is set to a value larger than "100" (for example, 277). By setting in this way, even when the game ball passes through the first type starting opening 27 and the RAM clear instruction is illegally issued at the same time,
The game ball is 0.2s after the first type start opening switch 27a
When it is detected by, the jackpot lottery counter Ct1
Is still counting "200", so there is no danger of an illegal big hit. (4) Further, in the above-described embodiment, the case where the initial value of the jackpot lottery counter Ct1 is reset to "0" when the RAM clearing process is executed has been described, but it is reset to a value other than "0". The present invention can be applied to the case. Also in this case, the time required to count the first big hit value from the initial value when reset is the timing when the game ball is detected by the first type starting opening switch 27a from the timing when the gaming ball passes through the first type starting opening 27. By setting the time so that it is longer than the time until, it is possible to eliminate the risk of illegal big hits. (5) The present invention can also be applied to a type 2 pachinko machine and a type 3 pachinko machine. Also, the first to third types
It can also be applied to a pachinko machine configured by combining any two or more of the seed pachinko machines. Further, the present invention can be applied to a gaming machine having a function of drawing a big hit or a loss, such as a slot machine, a sparrow ball, an arrangement ball, and other gaming machines installed in a game hall.
