Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention secures a right advantageous to a player by winning a pachinko ball at a predetermined winning opening, and the pachinko ball wins at another winning opening while securing the right. The present invention relates to the improvement of a pachinko machine that allows a player to exercise a favorable right.

[0002]

2. Description of the Related Art In a pachinko machine, a winning condition during a game is changed depending on the skill of the player, and generating a right advantageous to the player (hereinafter referred to as right) is a requirement for increasing the player's willingness to play. It is one.

For example, a game board of a pachinko machine is provided with a normal winning opening, a special winning opening, and a third-class starting opening, and a large winning opening capable of changing a pachinko ball into a first state in which it is easy to win and a second state in which it is not winning. There is one provided on the game board.

Then, a right is generated based on the winning of the special winning opening, and when the right is generated, the special winning opening driving source is driven when the third-class starting opening is won, whereby the big winning opening is moved to the second winning opening. The state is controlled to the first state. As a result, the right is exercised, and the number of prize balls obtained per unit time becomes larger than in the normal game.

This right is in the same situation as when the right is generated, when the number of pachinko balls that wins the third-class starting slot when the right is generated reaches a predetermined value, or when the right is generated, the prize is returned to the special winning slot. Disappears when is formed again.

In such a pachinko machine, the main configuration of the above-mentioned right generation means is an MPU, and whether or not to generate a right is determined by software (program) rather than the mechanism of the pachinko machine.
There is a model that depends on, and this kind of pachinko machine has a random number table configured by the above software.

Then, at the timing of winning a specific winning opening, one of the random numbers is read out from the above random number table, and when the read numerical value is a specific value, the pachinko ball launched on the game board becomes the special winning opening. It makes it easier to win the prize.

In this type of pachinko machine, the probability that the above-mentioned specific numerical value is read from the random number table on the software, that is, the right occurrence probability is not changed, and the pachinko machine is always fixed at a predetermined value, and a plurality of kinds of rights. There are models that change the probability of occurrence.

In the former, when all the rights are exercised, the rights are generated again based on the same probability, and in the latter, the rights are generated based on the changed probability when all the rights are exercised.

In the latter case, after the first right is generated or the first
After exercising the right for the first time, the probability of right occurrence after the second time is
There is a model that has increased (for example, 10 times) the original probability of the first time.

In the latter case, the first fluctuation of the right occurrence probability generally increases relatively with the occurrence of the right, and this fluctuation of the right occurrence probability is usually controlled by software. And the above-mentioned right generation means, namely MP
When changing the right occurrence probability, U executes either software with a relatively large right occurrence probability or software with a relatively small right occurrence probability.

In the latter type of pachinko machine described above, it is extremely easy to generate a right a plurality of times (for example, twice or three times) once the right is generated, as compared with the former.

As a result, in the latter case, the right is actually generated a plurality of times by one generation of the right, and the number of prize balls obtained when the right is generated is larger in the latter than in the former case. Therefore, the latter allows the player to have a greater sense of expectation for the number of prize balls than the former.

By the way, the software is utilized not only for changing the above-mentioned right occurrence probability but also for controlling each part of the pachinko machine by being executed step by step by the MPU.

The control software of each part of the pachinko machine, such as the fluctuation of the right occurrence probability, and various data constituting the random number table and the like are stored in the ROM provided in the control system of the pachinko machine, and the memory capacity thereof is stored. Has a predetermined upper limit.

For this reason, it is desirable that the software for the pachinko machine be constructed as simply as possible.

[0017]

Therefore, in the case of the pachinko machine in which the right occurrence probability fluctuates, a plurality of types of software and data (for example, a random number table) for changing the right occurrence probability must be stored. It becomes difficult to simplify the software for controlling pachinko machines.

For this reason, the restrictions required for developing the control software for the pachinko machine are increased, which causes a problem that the development efficiency is lowered and the development time is prolonged.

Therefore, an object of the present invention is to provide a pachinko machine for reliably generating the right a plurality of times without changing the probability of the right generation.

[0020]

In order to achieve the above object, the present invention is predetermined on the game board based on a normal symbol starting area and a pachinko ball passing or winning in the normal symbol starting area. Ordinary symbol display device for displaying a plurality of types of identification information for a predetermined period of time and stopping and displaying any of the identification information based on the end of the variation display, and a space portion for receiving a pachinko ball. A normal electric auditors product having a movable piece that takes a first state that easily accepts and a second state that does not accept, and the movable piece that is in the second state when specific identification information is stopped and displayed on the normal symbol display device. Is provided with a normal drive source for controlling the drive to the first state for a predetermined time, and in the space, the normal winning opening, the special winning opening, and the special winning opening is closed when the right is generated. Non-occurrence of And an opening / closing part for opening the special winning opening, and holding at least one pachinko ball during the closing operation of the opening / closing part, and holding the held pachinko ball to the special winning opening during the opening operation of the opening / closing part. And a holding portion that guides.

The normal drive source is configured to drive and control the movable piece in the second state for the predetermined time based on the pachinko ball passing or winning in the normal electric accessory starting area provided on the game board. I have it.

[0022]

With the above structure, when specific identification information is stopped and displayed on the normal symbol display device by the passage or winning of the pachinko ball to the normal symbol starting area, the normal drive source moves the movable piece in the second state for a predetermined period of time. Since the drive is controlled to be in the 1 state, the pachinko ball hit on the game board can be easily received in the space.

When the pachinko ball received in the space portion during the first state of the movable piece wins the special winning opening, the right is generated.

Further, when the right is generated, the pachinko ball guided to the holding portion remains in the holding portion as it is because the special winning opening is closed by the opening / closing portion, while when the right is not generated, the special winning opening is held. Is opened by the opening / closing part, so that the pachinko ball remaining in the holding part is guided to the special winning opening (prize) to generate the right.

In the case where the normal drive source is provided with a structure for driving and controlling the movable piece in the second state for the predetermined time based on the pachinko ball passing or winning in the normal electric accessory starting region, Based on the passing or winning of the pachinko ball to the electric accessory starting area, the pachinko ball hit on the game board is received in the space portion.

The rotary member position detection switch shown in FIG.
For example, the rotary member position detection switch 65 is composed of a pair of light emitting / receiving elements. To do. The relative positions of the recess 55 and the special winning opening 21 can be detected based on the detection of the specific portion.

Next, a procedure for using the pachinko machine 2 having the above-described structure will be described below with reference to FIGS. 11 and 12. First, when power is turned on, initial settings are made, and if normal, the player can play pachinko.

At the time of this initialization, the control circuit is
The motor 50 is stopped with the recess 55 facing the holding portion 30, and in the present embodiment, when the recess 55 faces the holding portion 30, the rotary member position detection switch 65 is turned on. Further, the storage stopper 28 keeps the recovery port 31 open.

When the pachinko ball 7 passes through the normal symbol starting gate 14, the winning ball is detected by the normal symbol starting switch, and this detection signal is input to the control circuit (see FIG. 11a).

At the same time, the control circuit normally operates the symbol display device 13 to display the identification information on the display units 15 to 17 in a variable manner for a predetermined time (see FIG. 11b), and then stop display of any identification information. To do. Then, the control circuit determines whether or not the stop-displayed identification information is specific identification information (see FIG. 11c).

If it is determined that the identification information stopped and displayed on the display units 15 to 17 is not the specific identification information, the movable pieces 18, 18
While being held in the second state, while waiting for the winning detection of the normal symbol starting switch, when it is determined that the identification information is specific identification information, the control circuit excites the solenoid 22 (see FIG. 11d). The probability that the specific identification information is normally stopped and displayed on the display units 15 to 17 of the symbol display device 13 is constant.

By the stop display of the specific identification information, the movable pieces 18, 18 in the second state shift to the first state (FIG. 11d).
At the same time, the recovery port 31 of the storage stopper 28 is closed. During the transition from the second state to the first state, when six or more pachinko balls 7 are taken into the space portion 19, the pachinko balls 7 from the first ball to the fourth ball are stored in the storage portion 26. The stored pachinko balls 7 after the fifth ball fly out obliquely downward from the guide hole 46 via the guide portion 27.

Of these, the fifth pachinko ball 7 is the holding section.
It is guided to the recess 55 of the holding portion 29 via 30 and thereby the sixth
The pachinko balls 7 of the balls are held in the holding unit 30 as a result of coming into contact with the pachinko balls 7 of the fifth balls in the recess 55 of the holding unit 29.

When 7 or more pachinko balls 7 are taken into the space portion 19, the pachinko balls 7 on and after the 7th ball are guided holes 46.
It jumps out of and collides with the sixth pachinko ball 7 on the holding section 30. This pachinko ball 7 wins a normal winning hole 20, a predetermined number of prize balls are paid out to the winning ball, and is not guided to the holding unit 29 and the holding unit 30.

After a lapse of a predetermined time from the shift of the movable pieces 18, 18 to the second state, the control circuit continuously operates the motor 50. As a result, the rotary body 48 is rotated, so that the rotary body position detection switch 65 is continuously switched from the ON state to the OFF state, and at the same time, the storage stopper 28 in the closed state.
Is transferred to the opened state by the control circuit (see FIGS. 11d and 11e).

When the recess 55 is moved to the special winning opening 21 by the rotation of the rotating body 48 described above, the pachinko ball 7 in the recess 55 is moved.
Wins the special prize hole 21. The winning ball is detected by the right generation / disappearance switch 62, and the detection signal shown in FIG. 11f is generated. Simultaneously with the fall of the detection signal, the first right is generated (see FIG. 11g), and the right mouth stopper 49 is activated.

At the first occurrence of the right, the third-class starting opening 6
When the pachinko ball 7 wins (see FIG. 11h1), the special winning opening 5 is continuously opened for a predetermined time and the first right can be exercised (see FIGS. 11i1 to 16). When the pachinko ball 7 wins the 16th prize in the 3rd type starting mouth 6 from the first occurrence of the right, all the first right is exercised,
Disappear at the same time. At this time, the probability that the specific identification information is normally stopped and displayed on the display units 15 to 17 of the symbol display device 13 does not change and is kept constant.

By the way, since the pachinko ball 7 is not accommodated in the recess 55 due to the winning of the special winning opening 21, the rotating body 48 faces the recess 55 to the retaining portion 30 from the first right generation. When it is rotated up to (Fig. 11j1), the pachinko ball 7 of the sixth ball is recessed 55 from the holding portion 30 due to its inclination.
Be guided to.

When the right is generated for the first time, since the right mouth stopper 49 is operated by the above-mentioned control circuit as described above, the special winning opening 21 is closed by the right mouth stopper 49. The body 48 is continuously rotated while holding a pachinko ball in the recess 55. As a result, it is possible to prohibit the pachinko ball 7 from winning the special winning opening 21 when the first right is generated.

Further, when the pachinko ball 7 passes through the normal symbol starting gate 14 at the time of the first generation of the right, any identification information is displayed on the display unit 15 based on the passing ball as described above.
Displayed at ~ 17.

This stop identification information is specific identification information, and when the movable piece shifts to the second state, the space 19
Even if the pachinko ball 7 is flown into the recess 55, the special winning opening 21 is closed by the right mouth stopper 49 of the holding portion 29, so that the pachinko ball flowing into the recess 55 is The holding unit 29 prevents the special winning opening 21 from winning.

The rotor position detection switch 65 generates a position detection signal each time the rotor 48 causes the recess 55 to face the holding portion 30 as the motor 50 rotates when the right is generated (see FIG. 11). And j1 to jn in FIG. 12), this position detection signal periodically repeats ON-OFF, the number of times of occurrence thereof is indefinite, and depends on the right generation time.

When the right is generated for the first time, the third type starting opening 6
When the 16th pachinko ball 7 is won (see FIG. 12h16), the first right is extinguished, and the operation of the right mouth stopper 49 is released by the control circuit.

As a result, the special winning opening 21 becomes ready for winning, so that the recess 55 becomes the special winning opening as the rotating body 48 rotates.
When moving to 21, the sixth pachinko ball 7 surely wins the special winning opening 21 from the recess 55 without requiring skill, and at this time, the specific identification information is displayed on the display unit 15 of the ordinary symbol display device 13. The probability of being stopped and displayed in ~ 17 does not fluctuate and is kept constant.

This winning ball is detected by the right generation / disappearance switch 62, and the detection signal shown in FIG. 12k is generated. Simultaneously with the fall of this detection signal, the second right is generated (see FIG. 12l), and the right mouth stopper 49 is activated, and thereafter, the third right is generated as in the case of the first right generation.
The second right is exercised based on the winning of the seed starting opening 6.

At this time, the probability that the specific identification information is normally stopped and displayed on the display portions 15 to 17 of the symbol display device 13 does not change,
It is held constant. After the second extinction of the right, the control circuit detects the state in which the recess 55 faces the holding portion 30 based on the rotary member position detection switch 65, and simultaneously stops the motor 50 (see FIG. 12e).

In the above embodiment, the case where 6 or more pachinko balls 7 are taken into the space portion 19 has been described.
When the pachinko ball 7 of the ball is taken in, the first right is generated when the pachinko ball 7 of the fifth ball wins the special winning opening 21 (see FIG. 13d).

However, since the holding part 29 or the holding part 30 does not hold or hold the pachinko ball 7 at the time of the first occurrence of the right, the second right immediately becomes available after the first right ends. Does not occur (Fig. 14h16 and Fig.
14i16). In order to generate the second right,
It means that five or more pachinko balls 7 must be newly won in the space portion 19.

Further, when the four pachinko balls 7 are taken into the space portion 19, none of the pachinko balls 7 is guided to the holding portion 29 or the holding portion 30, so that no right is generated in such a state. (See Figures 15 and 16). Figure
In FIGS. 13 to 16, the same signals as those in FIGS. 11 and 12 are designated by the same reference numerals, and the description thereof is omitted.

In the above embodiment, when the normal symbol display device 13 which is started based on the passage (or winning) of the pachinko ball 7 to the normal symbol starting gate 14 stops and displays the specific identification information, the second state The case where the movable pieces 18, 18 are shifted to the first state by the solenoid 22 has been described, but the invention is not limited to this, and the normal symbol starting gate 14 is the normal electric accessory starting region, and the normal symbol starting gate 14 is provided. The movable pieces 18, 18 in the second state may be configured to shift to the first state based on the winning of.

With this configuration, the solenoid 22 normally drives and controls the movable piece 18 in the second state for the predetermined time based on the pachinko ball passing or winning in the symbol starting gate 14. Ordinarily, the installation of the symbol display device 13 can be omitted.

[0113]

As described above, according to the present invention, the probability that the specific identification information is normally stopped and displayed on the symbol display device is fixed, and the right advantageous to the player is surely obtained without requiring skill. It can occur multiple times. As a result, it is no longer necessary to develop a plurality of types of software for stopping and displaying specific identification information on the normal pattern display device according to the type of probability. Accordingly, the restrictions on software for pachinko machines are reduced and reduced, and the degree of freedom in development is expanded, so that the workability of pachinko machine development is improved.

Since the right advantageous to the player is surely generated a plurality of times, a predetermined number of prize balls can be surely obtained after the right is generated regardless of the skilled player and the beginning player. As a result, it is possible to surely prevent a decrease in willingness to play due to the extinction of rights before the exercise of all rights when the rights are generated multiple times, and to eliminate the technical disparity between the skilled player and the beginner player regarding the number of prize balls. ..

When the movable piece in the second state is moved to the first state based on the winning of the ordinary electric accessory starting region, the installation of the ordinary symbol display device can be omitted, so that the configuration is simplified. Can be done easily and cost can be reduced.
