Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a gaming machine represented by a slot machine, an arrangement game machine, etc., in which games can be played using gaming cards made of magnetic cards or the like. It is related to gaming machines.

In particular, this invention has been improved so that by limiting the upper limit of game units that can be played within a certain period of time, the gambling nature of the gaming machine can be moderately suppressed, allowing all players to enjoy fair and healthy gaming. This relates to gaming machines.

[Prior Art] As an example of a gaming machine that is interesting to the present invention, a pachinko slot machine (hereinafter referred to as "pachislot") will be explained. Pachislot machines typically include three rotating reels (or rotating drums).

After inserting a predetermined number of coins or a magnetic card for gaming, you can start the rotation of the rotating reels by pressing the start button, and enjoy the display combinations when the rotation of the rotating reels stops. When a predetermined combination is achieved, a coin as a prize is paid out or a predetermined score is written on the magnetic card.

Current pachislot machines have one game cycle, that is, the game starts, the rotating reels are operated to rotate,
There are no restrictions on how many seconds or more it must be for the time from when the rotating reels start spinning until they stop, points are calculated, and the next game can start. Therefore, a player who is relatively familiar with gaming machines can play one game in a very short time (several seconds), and can play games one after another in a very short game cycle.

On the other hand, when considering the game content of pachinko machines installed in the same pachinko halls as pachislot machines, in the case of pachinko machines equipped with electric ball striking devices, the upper limit of the number of pachinko balls that can be fired per minute is generally Limited to 100 shots. Therefore, no matter which player
You can only fire a maximum of 100 pachinko balls per minute, and if you rent a predetermined number of pachinko balls, you can at least enjoy the game for gJ (minutes), which is the quotient of the number of balls divided by 100. is being used. In other words, if you look at it from a different perspective, anyone playing on any pachinko machine can enjoy playing the game for a certain amount of time, and they should be able to avoid wasting more than a predetermined amount of money within a certain amount of time. , it is said to be a gaming machine with reduced gambling characteristics.

[The problem that the invention aims to solve] However, in the case of pachislot, such game control is not performed, so in some cases, players can waste their money in a very short period of time and stop playing the game. There is also the risk of spending a large amount of money without fully enjoying yourself.

This invention was made in consideration of this background, and is aimed at general gaming machines such as pachislot machines.- It limits the upper limit of games that can be played within a fixed time, and limits the gambling system of gaming machines within a certain range. To provide a game machine which allows any player to play a healthy and enjoyable game while keeping the game to a minimum.

[Means for Solving the Problems] Simply put, the present invention is a gaming machine that allows games to be played using an information storage carrier in which predetermined game information is written, and that allows games to be played within a predetermined time. In this system, the number of game units is limited, or the required minimum playing time corresponding to the game unit is determined, and if more games are to be played, the game is disabled.

[Function] Since it is prohibited to play games excessively within a certain period of time or to play games in an extremely short cycle, the gambling nature of the gaming machine can be suppressed within a certain range.

The microcomputer 98 is a C
It includes a ROM 134 in which an operating program for the CPU 132 is stored, a RAM 136 which is a writable and readable storage circuit, and an input/output interface 138 for matching the signals of the CPU 132 and external signals.

FIG. 4 is an illustrative diagram of the memory map of the RAM 136. The RAM 136 has 2 points for counting points as a game unit.
It includes 0 counters CTI-CT20 and 20 timers T1-T20 provided corresponding to each counter.

In addition, in this embodiment, the control circuit of the pachislot machine 10 is constructed by a control circuit centered on the microcomputer 98, but the control circuit may also be constructed by a discrete circuit such as a combination of logic circuits. However, it can also be configured by a control circuit using a microcomputer and partially discrete logic circuits.

5A, 5B, 5C, and 6 are flowcharts for explaining the operation of the control circuit shown in FIG. 3. Next, the operation of the control circuit shown in FIG. 3 will be explained based on the flowcharts in FIGS. 5A to 6 and with reference to FIGS. 1 to 4 as necessary.

First, in FIG. 5A, when control starts, the microcomputer 98 waits for one of the game selection buttons 28a, 28b, and 28c to be pressed after the game card is inserted. For example, a button 28 that specifies the game unit "1"
When a is pressed, the score stored on the game card becomes 1.
It is determined whether the score is greater than or equal to 1 or 2, that is, if there is no score, the game end lamp 50 is turned on and the control ends.

If the score is 1 or more, the counter is incremented by 1 and the corresponding timer is started. Similarly, when the game selection button 28b specifying the game unit "2" is pressed, it is determined whether the score is 2 or more, and if the score is 2 or more, the counter is incremented by 2 and the corresponding timer is started. . Game unit “
The same control is performed for the game selection button 28c which specifies "3". As a result, if the number of game units to be played is 1, the counter CTI-1, CT2 to CT2O-0°, and if the number of game units to be played is 2, the counter CT1-2
, CT2-1, CT3 to CT2O-0, when the number of game units to be played reaches 3, counters CTl-3 and CT2
-2, CT3-1, CT4 to CT2O-0, ..., when the number of game units to be played reaches 19, the counter CT
l-19, CT2-18, CT3-17, ..., CT
19-1, CT2O-0, when the number of game units to be played reaches 20, counter CTl-20, CT2-19,
CT3-18, . . . , CT19-2, CT2O-1. Further, each time the count value of each counter reaches "1", the corresponding timer is started in sequence.

Thereafter, the microcomputer 98 puts the game machine into a game start state and waits for the start button 24 to be pressed by the player.

In response to turning on the start button 24, a signal is given from the microcomputer 98 to the driver 90, and the pulse motors 54a, 54b, 54c are started, and the rotating reel 22a is activated.
, 22b, 22c are rotated.

Stop button 26a by the player within a certain period of time.

26b, 26c is pressed or a certain period of time has elapsed, the microcomputer 98 starts rotating the rotating reels 22a, 2.
2b and 22c are stopped. That is, the pulse motor 5
Rotation of 4a, 54b, and 54c is stopped.

The microcomputer 98 has rotating reels 22a, 22
The combination of displayed pictures when the rotations of b and 22c are stopped is exposed and determined. When the displayed symbols are in the sequence of bonus symbols, a bonus chime sound is generated, and when the displayed symbols are not in the sequence of bonus symbols, winning is determined without generating the bonus chime sound. When the predetermined symbols are lined up, it is a win, and the microcomputer 98 calculates a score corresponding to the win and displays it on the score display 23. Furthermore, in the case of a bonus win, the number of bonus games is determined.

Here, the bonus game is a combination of predetermined symbols during 30 games, such as "7" and "watermelon mark."
It is the gaming value given when either rBARJ or rBARJ line up along the display line. The bonus game is
By pressing the game selection button 28a and turning on the start button 24, the three rotating reels 22a, 22b, 2
2c starts rotating. In addition, the game selection button 23b,
Even if you press 28c by mistake, you only need to subtract the score rlJ. When the stop button 26a is pressed, the left reel 22
A stops, but if the displayed "Jack" comes to the center at this time, the player wins the bonus game and gets a score of, for example, 15 points. Next, the center stop button 26b is activated, the center reel 22b is stopped by turning on the stop button 26b, it is determined whether a "jack" is displayed, and the score is calculated. The same applies to the right reel 22c.

Since the above-described control related to symbol display detection, winning determination, score calculation, and bonus game is not a feature of this embodiment, further detailed explanation will be omitted.

The feature of this embodiment is that the interrupt control shown in FIG. 6 is performed. Referring to FIG. 6, microcomputer 98 performs interrupt control shown in FIG. 6 at regular time intervals. That is, the CPU 32
Read the count value of 136 counters, check whether there is a counter with a count value of "20", and if there is,
The time value of the timer corresponding to the counter is detected. Then, it is determined whether the timer value TRI is one minute or more.

FIG. 7 is an illustrative diagram drawn to more clearly explain the contents of this detection control. With reference to Figure 7, RA
Counters CT1 to CT2O provided in M136 are incremented by "1" in order from CTI each time the game unit increases. For example, when a game unit "1" is detected, only the count value of the counter CTI becomes "1", the other counters remain "0", and the next game unit "2" is detected.
” is detected, the CTI becomes “2” and C10
becomes "1", and when the game unit is "3", CTI becomes "3", C10 becomes "2", and CTa becomes "1".
When the game unit becomes "20",
CTI becomes "20", C10 becomes "19",
..., CT2O becomes "1". When the game unit becomes "21", the CTI becomes "1" again, and so on. In addition, in response to the count value of the counter becoming "1", the CPU 132 causes the RAM 136 to
The corresponding timers T1-T20 are started, and the timers begin to elapse. For example, when the count value of counter CTI is "1", timer T1 starts elapsed time, and when the count value of counter CT2 is "1", timer T1 starts elapsed time.
2 starts aging, and so on.

Also, when the count value of the counter reaches "2o", if the count value of the corresponding timer, for example counter CT1, is "2o", the time measured by timer T1 is determined, and the measurement time exceeds 1 minute. It is determined whether or not.

If one minute has not yet elapsed, as shown in FIG. 6, the operation of any of the gaming machines, that is, the pachi-slot machine 10, is disabled until one minute has elapsed on the timer.

Disabling any of the operations of the Pachislot 10 means, for example: ■ Returning the game card; ■ Prohibiting the start switch; ■ Prohibiting the stop switch; ■ Prohibiting the rotation of the pulse motors 54a to 54c. etc.

In this embodiment, as shown in FIG. 3, the operation of at least one of the start switch and the stop switch is prohibited.

By doing this, only a predetermined number of games can be played within a certain period of time, and unnecessary accumulation of the number of games by wasting points is prevented.

In this embodiment, the counters and timers are configured by software using the microcomputer 98, but instead of this, 20 20-decimal counters are provided which reset themselves by outputting a count-up signal when counting 20 items. The 20 counters are connected on a ring such that a subsequent counter is activated in response to a "1" output of a preceding counter, and 20 counters are connected in a ring corresponding to each of the 20 20-decimal counters. FIG. 2 is an illustrative diagram showing an example of a display device having a configuration including a timer. As shown in Figure 8,
Arrange the game unit number display and time display on concentric circles,
If the usage ratio of the number of game units to the time is displayed, there is an advantage that it is possible to know at a glance how much of the game unit the user is using within a certain period of time.

Next, other control operations of the pachi-slot machine 10 will be explained.

FIG. 9 is an illustrative diagram of the storage contents of the RAM 136 necessary for performing the control described below in the control circuit of FIG. 3. As shown in Fig. 9, in this control,
The RAM 136 requires a so-called soft timer area for measuring time by integrating input signals from the CPU 132, a 1-point flag area, a 2-point flag area, a 3-point flag area, and a counter area for storing the number of coins inserted. be.

FIG. 10A, FIG. 10B, FIG. 10C, and FIG. 10D are flowcharts for explaining the control operation.

Next, based on the flowcharts of FIGS. 10A to 10D and with reference to FIGS. 1, 2, 3, and 9 as necessary, the control circuit shown in FIG. Other control operations will be explained.

First, in FIG. 10A, when the control starts and a game card is inserted, the microcomputer 98 detects whether any of the game selection buttons 2g a, 28 b, or 28 c is turned on. If it is turned on, it is determined whether there is a score corresponding to the game selection button that is turned on.

If there is a score, R based on the selection button turned on.
Turn on either the 1 point flag, 2 point flag, or 3 point flag of AM13B and start the timer. and,
Increment the counter value by the value corresponding to the flag.

Incidentally, by accumulating the count value of this counter, it is possible to memorize the game units played on the pachi-slot machine 10.

Next, the microcomputer 98 puts the pachi-slot machine 10 into a game start state and waits for the start button 24 to be pressed by the player. In FIG. 10B, a signal is given from the microcomputer 98 to the driver 90 in response to human power from the start button 24, and the pulse motors 54a, 54b,
54c is started, and the rotating reels 22a, 22b
, 22c is rotated.

Stop button 26a by the player within a certain period of time.

When 26b and 26C are pressed or a certain period of time has elapsed, the rotating reels 22a, 22b, 22c
to stop. That is, the pulse motors 54a, 54b
, 54c are stopped.

10C, the microcomputer 98 detects and determines the combination of displayed symbols when the rotation of the rotating reels 22a, 22b, and 22c has stopped. Note that the control regarding score calculation and bonus game after this control is the same as the control in the previous embodiment described above.
The explanation here will be omitted.

The feature of this embodiment is that the control shown in FIG. 10D is performed. Referring to FIG. 10D, microcomputer 98 accesses the flag area of RAM 136 after completing one game or after completing a bonus game,
It is determined whether the 1 point flag is on, the 2 point flag is on, or the 3 point flag is on. If the 1-point flag is on, check whether the timer T value is 3 seconds or more, and if the 2-point flag is on, check whether the timer T value is 6 seconds or more.
If the 3-point flag is on, it is determined whether the value of timer T is 9 seconds or more. If the value of the timer T has not reached the predetermined number of seconds, the specific operation of the pachi-slot machine 10 is disabled until the timer value of the timer T reaches the predetermined number of seconds. Disabling a specific operation means, for example, disabling the game selection button or disabling the start button 24.

By doing this, only a predetermined number of game units can be played within a certain period of time, and after that, it becomes impossible to accumulate the number of games unnecessarily by wasting the first place of the second game.

[Effects of the Invention] As described above, according to the present invention, since the maximum number of gaming units that can be used for gaming within a certain period of time is limited, only a certain number of points can be used within a certain period of time. First, it is possible to provide a gaming machine in which the gambling nature is suppressed within a certain range, and which allows any device or any player to enjoy the game relatively fairly.
