Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a control device for a winning ball device in a pachinko game machine, and in particular, to a control device for a winning ball device in a pachinko game machine, and particularly to a control device for controlling a winning ball device that is awarded to a player when a certain gaming state is entered. It is controlled by a ball device.

[Prior Art] In general, a pachinko game machine (hereinafter referred to as "pachinko machine") that plays a game by hitting pachinko balls (hereinafter referred to as "balls")
) has become widely popular and is popular among players as one of the easy cash registers. As is well known, a pachinko machine has a plurality of safe holes and a winning ball device (Yakumono, commonly known as a chulip) arranged on the game board, and when a ball is hit into the game board, the probability that the ball will be hit is determined. If you win in the safe hole or Yakumono, a certain number of prize balls (usually 13 to 15) will be released. In order to improve services for players, conventional pachinko machines open a predetermined number of yakumono when a ball hits a certain safe hole or a winning area, or It only took time.

[Problems to be Solved by the Invention] In the above-mentioned conventional pachinko machines, the number of Yakumono that can be arranged is limited at most because the size of the game board of the Pachinko machine is limited. There are only a few prize balls, and since the Yakumono closes when one winning ball enters, the number of prize balls generated is only a few dozen at most, and it cannot be a great service to players, and the game The drawback was that people easily got bored with it.

On the other hand, if you open a Yakumono for a predetermined time, depending on the setting of the predetermined time, if you set the time too short, the number of safe balls that will be generated will be 2 to 2.
3, which cannot provide a great service to the players, similar to the above-mentioned pachinko machine. vice versa,
Set the setting time to a relatively long time (for example, 30 seconds to 1
If this is set, the number of winning safe balls will increase, which will provide a service to the players, but the service will not be given equally to all players, and the amusement center will suffer a great deal of damage. There is also a risk that the pachinko machine may further arouse the gambling spirit. For example, if the setting time is 30 seconds, the number of balls that can be fired in that 30 seconds is usually about 50, and of the 50 balls fired onto the game board, the balls that enter the open Yakumono are It is conceivable that there is a considerable difference in the number of balls (about 20 to 30 balls) between a so-called expert player and an ordinary player. Therefore, this may result in a large amount of prize balls being awarded only to a specific player. In addition, if the game hall intentionally adjusts the nails on the game board so that most of the balls that are driven into the game are guided to the open game, even if the set time is 30 seconds, However, the number of prize balls generated was several hundred, which had the drawback of stimulating the gambling spirit too much.

[Means for solving the problems] In order to solve the above-mentioned drawbacks, the present invention has the following features:
A winning area into which pachinko balls flow is formed, and a ball receiver member that can be opened and closed to guide the pachinko balls to the winning area is provided on the front side of the winning area, and an electric drive that opens and closes the ball receiver member is provided on the back side of the winning area. A winning ball device having a mounting board provided with a power source attached to a game board of a pachinko game machine, and counting a predetermined number of pachinko balls that enter the winning area when the ball receiving member is in an open state. a control means including a winning ball counting means and a clocking means for counting a predetermined period of time from when the ball receiving member is in the open state; The electric driving source is operated until either one of the ball counting means output and the time measuring means output is applied first.

[Operation] In principle, the winning ball device is held open for a relatively long predetermined time (for example, 30 seconds to 1 minute) to facilitate winning of prize balls. On the other hand, within that predetermined time, a predetermined number of items (for example, 10 to 15 items)
When the number of balls) enters the winning ball device, the winning ball device is opened. As a result, 1 of the winning ball device
There is little difference in the number of prize balls obtained depending on the number of rounds, whether it is an expert player or an ordinary player. At the same time, the number of prize balls can be dispensed in a number that is not too small for the player, but is not so large as to arouse the gambling spirit.

FIG. 1 shows an embodiment of a game control circuit in a winning ball device for a pachinko machine, which is a feature of the present invention. In this structure, the flip-flop 61 is used to store and hold the fact that there are special prize balls that have passed through the special prize area 14. The timer 63 as a timing means operates after the ball receiver members 33a, 33b of the variable winning ball device 30 start being driven to the expanded state, and operates for a relatively long fixed period of time (for example, 30
It generates a time-up signal when the timer (seconds) has elapsed. The counter 64 counts the output of the winning ball detection switch and derives a count-up output when a predetermined number (for example, 10) of winning balls have been counted. These counter 64 and winning ball detection switch 224 constitute winning ball counting means. The AND gate 62 operates the solenoid 5 based on the presence of the output of the flip-flop 61 (that is, the detection of a special prize ball).
1 is driven, and in response to either the time-up signal of the timer 63 or the count-up output of the counter 64 being applied, the driving of the solenoid 51 is stopped.

Next, the operation of this embodiment will be explained with reference to FIGS. 1 to 6. First, the ball is safe hole 12.
In response to winning a prize, the ball receiving members 33a, 33
A case will be described in which the ball receiver members 33a and 33b are closed based on the winning balls entered into the winning hole 35 while b is opened. When the hit ball enters the safe hole 12, the winning ball is guided to the passage 463 via the path 211. At this time, the winning ball is placed on the ball mounting portion 472 of the rotating lever 47.
The ball rests on the ball and uses its own weight to rotate the rotating lever 47 counterclockwise. At this time, the engagement pin 413 engaged with the other end of the rotary lever 47 is pushed upward as the rotary lever 47 rotates. As a result, the engagement pin 413 presses the lever 43 while coming into contact with the arcuate portion 432 of the lever 43. Then, when the engagement pin 413 is pushed up to the upper position, the engagement pin 413 and the projection 433 of the lever 43 engage with each other, thereby locking the engagement pin 413. At this time, when the engagement pin 413 is pushed upward, the lever 41 rotates clockwise around the cylindrical part 411, and the cylindrical shaft 331 fitted into the cylindrical part 411 is rotated. Then, the ball bearing member 33a rotates outward. At the same time, the lever 42 loosely fitted into the engagement protrusion 412
is rotated counterclockwise, the cylindrical shaft 331' inserted through the lever 42 is rotated, and thereby the ball bearing member 33b is rotated outward. In this way, the ball bearing members 33a, 33b are opened.

When the ball receiver members 33a, 33b are rotated outward and opened, balls can be won into the winning area 32 and the winning hole 35 that were previously covered by the ball receiver members 33a, 33b. Then, the driving ball is inserted between the guide protrusions 37a and 37b, between the guide protrusions 37a and 38, or between the guide protrusions 3
It falls through between 7b and 38 and enters the winning hole 35. Accordingly, the winning ball is guided laterally through the path 314, placed on the ball mounting piece 435 of the lever 43, and rotated clockwise to move the winning ball into the through hole 4.
52. By rotating the lever 43,
The engagement state between the engagement pin 413 and the engagement portion 433 is released, the lever 42 rotates counterclockwise, and the ball receiver members 33a and 33b are accordingly rotated inward to close. With this, the ball bearing member 3
3a, 33b are open, when one ball hits the winning hole 35, the ball is immediately moved to the ball receiving part 33a.
and 33b is closed.

On the other hand, when the ball receivers 33a and 33b are in the open state, when the ball passes between the guide protrusions 37a and 38a or between the guide protrusions 37b and 38b and reaches the ball receiver member 33a or 33b, The balls are guided by the ball receiving members 33a, 33b to the winning area 32 below and then to the back side of the game board via the winning area 32. At this time, the ball bearing member 3
The ball guided by 3a and 33b is moved to the lever 43
Since the ball bearing members 33a and 3 do not rotate at all,
Do not open 3b. Therefore, no matter how many balls are guided to the winning area 32 by the ball receivers 33a and 33b, the ball receivers 33a and 33b are not closed at all and remain continuously opened.

In this way, the ball receiving members 33a and 33b are opened in accordance with the winning ball entering the safe hole 12, thereby allowing the ball to enter the winning area 32 and the winning hole 35, and the ball being hit into the winning area 32. Since the ball receiving members 33a and 33b are configured not to be closed at all as far as the player is concerned, there is an advantage that the player has the opportunity to win a large amount of prize balls.

If the ball is unlucky to land in the winning hole 35, the ball receiving members 33a and 33b are immediately closed,
Thereafter, the state changes from a state in which it is easy to win a prize to a state in which it is impossible to win a prize. In this case, the driven ball is placed at the guide protrusion 37
No matter how many times the ball passes through each of the holes 33a, 37b, 38a, and 38b, the ball is bounced by the outer arc portions of the ball receiving members 33a and 33b, so it is not given a chance to enter the winning area 32 and the winning hole 35. .

Note that the above operation is not related to the gist of the present invention and is merely an explanation of one operation of this embodiment.

Next, in response to the ball hitting the special prize area 14, the ball receiving member 33a, which is a feature of the present invention,
The operation when opening 33b will be explained. The special prize area 14 is located at a position where it is difficult for the player to win even if the player aims for it, and where the player can win the prize with a certain degree of chance (in the illustration, directly below the variable winning ball device 30). is formed. If the hit ball is lucky enough to land in the winning area 14, the special prize ball will be detected by the special prize ball detection switch 24 as it falls through the path 215. When the special prize ball detection switch 24 detects a special prize ball, the flip-flop 61 is set by its output. The set output of flip-flop 61 is applied as one input to AND gate 62 and as an operation command signal for timer 63. The timer 63 is
After the operation command signal is given, the variable winning ball device 3
A relatively long fixed period of time (for example, 30 seconds) that allows opening of the ball bearing members 33a and 33b of 0
This is to derive a high level signal. This high level signal is given as one input to AND gate 62. The count-up output (high level signal) of the counter 64 is inverted to a low level signal and provided to the AND gate 62 as the remaining input. However, in the initial state, since the counter 64 does not output a count-up output, the low level signal of the counter 64 is inverted to a high level signal and is applied to the AND gate 62. Therefore, and gate 62
derives a high-level signal at the same time that flip-flop 61 is set, and energizes solenoid 51 with this high-level signal. In response, the solenoid 51 attracts the plunger, thereby pulling down the L-shaped lever 53 and rotating the rotating lever 47 electrically. Therefore, the ball bearing members 33a and 33b are opened in the same manner as the above-described operation.

Then, the balls are guided by the ball receiving members 33a and 33b which are opened in an expanded state, and are guided to the winning area 3.
When a prize is won in 2, the number of winning balls is guided to a path 214. When the winning balls are dropped one by one in the path 214, the winning ball detection switch 224 detects this and gives a counting command signal (pulse) to the counter 64. The counter 64 keeps its output at a low level until it counts a relatively large predetermined number of winning balls (for example, 10). Therefore, until a relatively long fixed period of time set by the timer 63 elapses or until the counter 64 counts a predetermined number of winning balls, whichever comes first,
The AND gate 62 is activated and the solenoid 51 is in an energized state. Therefore, the hit ball enters the winning area 32 with a relatively high probability. At this time, even if the winning ball enters the winning hole 35, the solenoid 51 is energized and holds the rotating lever 47 in a rotating state, so the ball receiving member 3
3a and 33b remain open. Therefore, the player can win many prize balls with a relatively high probability and in a short period of time.

Then, a time-up signal (signal that inverts from high level to low level) is derived after a certain period of time has elapsed since the timer 63 is activated, or the counter 63
4 counts a predetermined number of winning balls and outputs a count up (a signal that inverts from low level to high level)
By deriving , the output of the AND gate 62 is inverted to low level. As a result, the solenoid 51 is deenergized and turned off, and the ball bearing member 33a,
33b is closed.

In other words, when the special prize ball detection switch 24 detects a special prize ball, the solenoid 51 is energized and turned on, and the ball receiving members 33a and 33b are opened. Then, the solenoid is deenergized and turned off based on the output of the timer 63 counting a certain period of time or the counter 64 counting a predetermined number of winning balls, whichever comes first, and the ball receiver members 33a, 3
3b is closed.

In addition, in the above-mentioned embodiment, the case where the open state is the expanded state in which the ball receiver members 33a and 33b are opened was explained, but the open state is not limited to this, and includes the open state and the closed state. It may be a state in which the above steps are repeated. This is because even if the ball bearing members 33a and 33b are repeatedly opened and closed,
This is because the balls can easily enter the winning area 32 in the same way as in the expanded state.

In addition, the flip-flop 61 and the counter 6
4, the time-up output (signal inverted from high level to low level) of the timer 63 is input to the differentiating circuit 6.
It is reset or cleared by the differential pulse differentiated falling at 5. Therefore, flip-flop 61 and counter 64 can return to their initial states and prepare for the next input. It should be noted that the differential circuit 65 has a symbol (-) attached thereto.
This is a differentiating circuit that performs falling differentiation, but does not perform rising differentiation of a signal that is inverted from a low level signal to a high level signal. This is to prevent the differential pulse from being output when the timer 63 operates.

In the description of the above embodiment, the ball bearing members 33a, 3
3b shows the one that opens and closes to the left and right, but the game board 1
A door-shaped ball receiving member may be provided in parallel with 1, and the ball receiving member may be opened and closed. Also, the ball bearing member 33
Although we have taken up an example in which a ball enters the special prize area 14 provided on the game board 11 as a condition for opening a, 33b, the condition is not limited to this. When the state is reached, the ball receiving members 33a and 33b may be opened.

[Effects of the Invention] As described above, according to the present invention, when the ball receiver member of the winning ball device opens under certain conditions, the ball receiver member is continuously opened for a certain period of time from the time of opening. Therefore, the player can obtain enough prize balls in a short time to satisfy the player, and the player's interest can be further increased.

In addition, the condition for closing the ball holder member in the open state is not only for a certain period of time as described above, but also when a predetermined number of pieces are counted before a certain period of time has elapsed, so that the ball holder member is in the open state. In this way, it is possible to reduce the difference in the number of winning balls between an expert player and an ordinary player. As a result, equal service can be provided to players, and the number of prize balls obtained by opening the ball receiving member once can also be reduced.
The number of pachinko machines is at a level that is desirable for both the gaming parlor and the players, does not overly arouse the gambling spirit of the players, allows the players to play with interest, and is desirable for the gaming parlor management. It has the effect of being
