Description

[Detailed description of the invention] This invention relates to a variable winning device for a pachinko machine.

As a conventional variable winning device, when a ball hits a prize between a pair of opening/closing wings pivoted on the left and right sides of the winning opening, the opening/closing wings alternately move up and down, changing the winning rate. It is a so-called chulip type winning tool, or it consists of two large and small winning holes with different winning rates at the upper and lower ends of a rotating body, and each time a ball hits a prize, this rotating body alternately rotates 180 degrees to increase the winning rate. There are various types of machines called rotary prize winning devices, each of which is useful for increasing the interest of pachinko.

However, in the former tulip-type winning device, when the winning ball rolls backward on a seesaw board built into the tulip device, the seesaw board is tilted by the weight of the winning ball to open the opening and closing wings. In most cases, when the next ball hits between these opened wing pieces, the seesaw plate is restored to its original state and the wing pieces are closed.
Since the opening and closing operations of the wings are performed by the mechanical action of the seesaw board, and this mechanical action is performed by the weight of the winning ball itself, the support of the wings is extremely unstable. Therefore, the blades move accidentally due to impact such as when a hit ball flowing down the surface of the game board comes into contact with or comes into contact with an open wing piece, and the reaction force closes the open wing piece. A phenomenon has occurred that greatly reduces the interest of players. Some devices are equipped with locking means to prevent this phenomenon, but this increases the number of parts, which not only causes manufacturing difficulties and costs, but also causes malfunctions due to the complexity of the mechanism. I was getting used to it. The latter type of rotating body simply repeats a monotonous movement in which the rotating body rotates 180 degrees alternately every time a ball hits a prize, and it is not able to satisfy the interest of the game.

As described above, all conventional variable winning devices operate monotonously and slowly, which limits the winning rate. Particularly in the tulip system, unexpected closing, jamming, and poor opening due to the sudden movement of the blades are constant. It was something I didn't have.

In addition, a ticket type winning device is attached from the front side of the game board and is driven to open and close individually by a drive device attached as a separate part to the back side of the game board, or a plurality of ticket prize winning devices installed in the same way. There are some that open and close in relation to each other,
Since the ticket-type winning device itself does not have an individual drive device, it is difficult to connect them, which complicates the assembly process of the pachinko machine.

Therefore, the main purpose of this invention is to provide a variable winning device that can eliminate the above-mentioned drawbacks of conventional variable winning devices and can double the interest in pachinko.

The purpose and features of this invention will become clearer in the following detailed description with reference to the drawings.

According to this invention, a first inlet is provided below the board attached to the front surface of the game board, and a second inlet is provided above with a width larger than the first inlet. Rotating a rotating receiving frame member that integrally forms a first prize opening that communicates with the first introduction port and which is difficult to accept a batted ball, and a second prize opening that communicates with the second introduction port and easily accepts a batted ball when rotated. A drive device is disposed on the rear side of the substrate to convert the rotary receiving frame member from the first winning hole to the second winning hole, and at least a winning ball received by the first winning hole is disposed on the rear side of the substrate. A detector for detecting the ball is integrally configured, and a detection signal from the detector is used to operate the drive device to rotate the rotary receiving frame member to change the receiving state of the batted ball. A variable winning device for a pachinko machine is provided.

This invention will be explained below based on the embodiments shown in the drawings. 1 to 7 show an embodiment of the variable prize winning device A according to this invention.

Reference numeral 1 denotes a square-shaped substrate, and a first introduction port 11 having a relatively small opening is located at the lower center of the substrate 1.
Furthermore, second introduction ports 12 each having a relatively large opening are provided at the upper center. A recess is provided in the center of the board 1, and a boss is protruded from the rear thereof, serving as a bearing 13 that supports a rotating shaft 23 (described later) (see Fig. 6). Arc-shaped long hole 1 with the center of curvature at the center
4 is bored so that an operating pin 33 (described later) can freely move therein.

Reference numeral 2 denotes a rotary receiving frame member which is rotatably attached to the front surface of the substrate 1 at a constant interval.The rotating receiving frame member 2 is a rectangular box-shaped member with two sides removed, 1 Surface member 2 facing the front surface
A rotary shaft 23 is attached to the boss 22 so that a boss 22 protruding from the center of the substrate 1 is loosely fitted into a recess of the substrate 1.
is fixed on the shaft. In order to allow the rotating receiving frame member 2 to rotate smoothly, it is preferable to interpose a metal pipe 15 made of brass or the like between the bearing 13 of the substrate 1 and the rotating shaft 23 to form a sliding bearing (see FIG. 6). ). Further, a semicircular hole 25 that is slightly longer than a location perpendicular to the side member 24 is bored in the face member 21 .

Next, a winning opening formed by the rotary receiving frame member 2 configured as described above and the introduction ports 11 and 12 formed in the substrate 1 will be explained.

When the rotary receiving frame member 2 is in a state where its longitudinal direction is perpendicular to the substrate 1 (as shown in FIGS. 1 to 3),
(see figure), the hole 25 drilled in the face member 21 of the rotary receiving frame member 2 is located at a position aligned with the first introduction port 11 of the substrate 1, and the side member 24 thereof is aligned with the lower side of the first introduction port 11. It's becoming like that. In this state, a pair of left and right side members 26, 26 rise vertically from both ends of the side member 24, and the first
A ball guide wall is configured with a relatively narrow interval l ₁ equal to the opening width of the introduction port 11, and the first introduction port 11
The first prize opening 27 is constituted together with the side member 24 that coincides with the lower side thereof. This first prize opening 27
Since the interval _l1 between the ball guide walls is relatively narrow as described above, the first winning hole is difficult to accept a ball. If the ball falls within the interval _l1 , it is guided by the ball guide wall made up of a pair of side members 26, 26, is received by the lower side member 24, and rolls on the side member 24. and flows into the first inlet 11. Note that the side member 24 is inclined toward the first introduction port 11 so that the ball can easily roll. In addition, the front of the ball guide wall, that is, the front of the rotating receiving frame member 2, is open so that you can see how the ball hits the prize, but there is no need to open this part, and it can be made with a transparent plate or decorated beautifully. It may be closed with a plate member etc. When the longitudinal direction of the rotating receiving frame member 2 is aligned with the vertical direction of the substrate 1, the first inlet 11 is opened by the rotating receiving frame member 2 (plane member 21) itself, as shown in the figure. The opening of the second introduction port 12 bored upward is closed.

Next, in the state shown in FIG. 5 in which the rotating receiving frame member 2 is rotated 90 degrees with respect to the substrate 1 (rotated 90 degrees clockwise), one of the pair of side members 26, 26 A second prize opening 28 is formed by the side member 26 that is aligned with the lower side of the opening 12 and extends in the horizontal direction and the second introduction opening 12 .

This second prize opening 28 not only does not restrict the opening of the relatively large second introduction port 12 in any way, but also has a side member 26 that acts to catch the batted ball.
The length _l2 extending in the horizontal direction further exceeds the opening width L of the second inlet 12, and both left and right ends of the side member 26 are inclined obliquely upward, so that the length of the side member 26 is All of the batted balls falling within the range of l ₂ will be guided to the second introduction port 12, which will become a winning port that is extremely easy to accept batted balls. Incidentally, when the rotating receiving frame member 2 rotates and the second winning hole 28 appears, the rotating receiving frame member 2 is no longer associated with the first introduction port 11, so the first winning hole 27 is no longer formed.

Next, a driving means for rotationally driving the rotary receiving frame member 2 will be described.

Reference numeral 3 denotes an action plate disposed on the back side of the base plate 1 so as to face the rotary receiving frame member 2 via the base plate 1. In this embodiment, it is composed of a partially cut out disk. A boss 31 is provided protrudingly on the (surface facing the rotating receiving frame member 2) at a position corresponding to the boss 22 of the rotating receiving frame member 2.
The rotating shaft 23 is supported by the rotating shaft 23 . Also, boss 3
In addition to 1, a boss 32 is provided protrudingly at a location corresponding to the elongated hole 14 of the board 1, and this boss 32 has an operating pin 3.
3 is inserted, and this operating pin 33 protrudes to the front through the elongated hole 14 so as to be parallel to the rotating shaft 23, and one end thereof is adapted to be inserted into the surface member 21 of the rotating receiving frame member 2. . In addition, the operating pin 33
is fixed at one end to the substrate 1, and a force is constantly applied by a return spring 34 in the biasing direction of the return spring 34. Reference numeral 35 designates an engagement pin protruding from the other surface of the actuation plate 3, which engages with a notch 42 provided at the end of the actuation lever 4, which will be described later.

Rotating support frame member 2 and operation board 3 relative to base plate 1
For example, the assembly of the rotating receiving frame member 2 (surface member 21)
With the rotating shaft 23 attached to the boss 22 of the board 1, the rotating shaft 23 is inserted into the bearing 13 of the board 1, and the boss 22 is loosely fitted into the recess of the board 1, so that the rotating shaft 23 protruding from one end of the bearing 13 is actuated. Board 3 boss 31
At the same time, the operating pin 33 inserted into the boss 32 is inserted into the rotary receiving frame member 2 (face member 21) through the elongated hole 14, and the boss 22 of the rotating receiving frame member 2 and the operating Board 3 boss 31
This is done by attaching a retaining ring or the like to one end of the rotary shaft 23 protruding from the boss 31 of the actuating panel 3 in such a manner that the bearings 13 of the board 1 are sandwiched between the bearings 13 of the board 1 (see FIG. 7).

An operating lever 4 is disposed at the rear of the operating panel 3 assembled in this way, and a bearing 41 is provided at one end of the operating lever 4, and a shaft pin is fixed to the base plate 1 on this bearing 41. 16 is inserted, the operating lever 4 is rotatably attached to the base plate 1 about the shaft pin 16. In this way, the actuating lever 4 is connected to the base plate 1 by the shaft pin 16.
Therefore, the shaft pin 16 may be fixed to the actuating lever 4 so as to be rotatably supported by the base plate 1.
The other end of the actuating lever 4 is provided with a U-shaped notch 42 elongated in the longitudinal direction, and the engagement pin 35 of the actuating plate 3 engages with the notch 42, so that the actuating plate 3 is moved by the movement of the actuating lever 4. It's starting to follow. Also,
A pair of engagement pins 43 are provided in the middle part of the operating lever 4.
43 is provided protrudingly, and the actuating piece 5 of the solenoid 5 is inserted here.
A disk 52 provided at one end engages. The solenoid 5 has a pair of support columns 17 protruding from the base plate 1.
17 via stays 53, 53, and when biased by control devices 8, 9 (to be described later), the actuating piece 51 compresses the return spring 54 due to its driving force and moves as shown by the arrow in FIG. Move downward as shown in a. Therefore, when the solenoid 5 is energized, the actuating lever 4 moves the shaft pin 1 through its engaging portion (the engaging pins 43, 43 and the disk 52 that engages with them).
6 in the counterclockwise direction in Fig. 4 (in Fig. 4, the solenoid 5 is
), and as the actuating lever 4 rotates, the actuating plate 3 is rotated by the engaging portion at its end (the notch 42 of the actuating lever 4 and the engaging pin 35 of the actuating plate 3 that engages with this). It rotates counterclockwise around the rotating shaft 23 against the tension of the return spring 34. Operation panel 3
The rotation of the operating pin 33 means that the operating pin 33 moves freely within the elongated hole 14 (arc movement with the rotating shaft 23 as the center of curvature), and the rotating receiving frame member 2 and the operating plate 3 move around the rotating shaft. 23, operating pin 33
As described above, since they are connected in such a manner that the substrate 1 is sandwiched therebetween, the rotating receiving frame member 2 also rotates counterclockwise about the rotating shaft 23 due to the driving force of the operating pin 33. At this time, the engagement pin 35 is provided at an appropriate position on the actuation plate 3 so that when the actuation lever 4 is rotated approximately 30 degrees by the driving force of the solenoid 5, the actuation plate 3 and the rotating receiving frame member 2 are rotated 90 degrees. (See Figure 4).

FIG. 5 shows a state in which the rotary receiving frame member 2 has finished being rotated by the drive means constructed as described above. The state shown in FIG. 5 is a state in which the second winning hole 28 that easily receives a batted ball is formed as described above.
When the solenoid 5 is deenergized, the return spring 54 and the return spring 34 to which the operating pin 33 is engaged rotate the operating plate 3, the rotary receiving frame member 2, and the operating lever 4 in the opposite direction to those described above. The first winning hole 27 returns to the state shown in FIG. 4 in which it is relatively difficult for the ball to win a prize.

Behind the first introduction port 11 and the second introduction port 12, there is a guide gutter 18 (in the drawings) consisting of a guide wall and a back plate in order to guide the winning batted balls to a predetermined location on the back side of the game board (for example, a prize ball discharge device). In order to avoid complication, a guide trough 18 corresponding to the second inlet 12 is installed.
Although only the rotary shaft 2 is shown, the drive device (particularly the rotating shaft 2
3) It is bent and extended as shown in the figure so as not to interfere with.

6 is a detector consisting of a micro switch fixed to the substrate 1, and its switch lever 61 is arranged behind the introduction port 11, and when a ball hits the first winning port 27, the winning ball is activated by this switch lever. 61, a detection signal indicating that a winning ball has been detected is output to the control devices 8 and 9 illustrated in FIG. The detector 6 is not limited to a micro switch as long as it detects that the ball has entered the first winning hole 27 and outputs the detection signal to the control devices 8 and 9. For example, a magnetic or oscillating proximity switch or an optical detector such as a photo sensor may be used. Further, the detector 6 may not be fixed to the substrate 1 near the back side of the inlet as shown in the figure, but may be provided at an appropriate location in the flow path for winning balls provided in association with the guide gutter 18. In addition, 19
is a partition plate for preventing the winning balls flowing down from the second introduction port 12 from touching the switch lever 61.

FIGS. 8 and 9 show embodiments of a control device for controlling the energization of the solenoid 5, and the specific configuration and operation thereof will be explained below.

The control device 8 shown in FIG. 8 controls the rotary receiving frame member 2 when the ball enters the first winning hole 27, which is relatively difficult to enter, and the winning ball is detected by the detector 6.
The solenoid 5 is energized for a certain period of time so that the ball rotates 90 degrees to form a second winning hole 28 that is easy to receive a ball, and then the energization of the solenoid 5 is stopped after the certain period of time has elapsed, so that the ball is returned to the original first winning hole 27.
When a ball enters the first winning hole 27, a detection signal from the detector 6 sets a flip-flop (hereafter referred to as FF) 81. The set output of the FF 81 turns on a driver 82, which in turn energizes a solenoid 5 connected to the driver 82. When the solenoid 5 is energized, the rotary receiving frame member 2 rotates 90 degrees through the mechanical operation described above, and the second winning hole 28 appears, which is easy to receive a ball.
The set output of 1 is applied to an oscillator circuit 84 consisting of a Schmitt NAND gate 83, a resistor R, and a capacitor C, and the oscillator circuit 84 starts oscillating. A subsequent ring counter 85 receives the continuous pulses generated by the oscillator circuit 84.
When the time for one revolution has elapsed, the FF81 is reset. By resetting the FF81, the driver 82 is turned OFF and the energization of the solenoid 5 is stopped. In response to this, the rotary receiving frame member 2 is returned to its initial state, that is, to the first winning hole 27. In this way, the control device 8 determines whether the ball is in the first winning hole 27.
After the winning is made, the solenoid 5 is energized for a certain period of time to make the second winning hole 28 appear.
The solenoid 5 is energized for a certain period of time by the oscillator circuit 8.
By changing the oscillation frequency determined by the product of resistor R and capacitor C of 4, it can be easily adjusted over a wide range.

Next, the control device 9 shown in FIG.
The solenoid 5 is energized to make the second winning hole 28 appear by rotating the second winning hole 28, and the solenoid 5 is energized regardless of time until N (for example, 10) batted balls enter the second winning hole 28. 1 is an example of a control device that continues. The detector 7 is the second prize opening 28
If this detector 7 is a micro switch, for example,
The switch lever may be arranged so as to protrude into the guide gutter 18 extending from the back side of the second introduction port 12. Note that this detector 7 is shown in Figures 1 to 7.
Not shown in the figure. When the batted ball enters the first winning hole 27, the detection signal from the detector 6 is sent to the FF91.
Set. The set output of the FF 91 turns on the driver 92 and energizes the solenoid 5 connected to the driver 92. When the solenoid 5 is energized, the rotating receiving frame member 2 rotates 90 degrees, and the second
A prize opening 28 appears. On the other hand, the set output of the FF 91 is differentiated by a differentiating circuit 93 to reset the count value of the N-ary counter 94. If a prize is won while the second prize opening 28 has appeared,
The N-ary counter 94 counts the number of winning balls each time the detector 7 detects the winning ball.
When the player counts a predetermined number of winning balls (N balls), a count-up output is derived and the FF 91 is reset. In response to this, the driver 92 is turned off, and the rotating receiving frame member 2 returns to its initial state, that is, the state of the first prize opening 27. In addition, in the same way as the conventional lottery type winning device, when one batted ball wins, the solenoid 5 is deenergized and the second winning hole 2 is turned off.
Of course, it is also possible to control to convert from 8 to the first winning hole 27, and in this case, the detector 7
straight line without passing through the N-ary counter 94.
It can be connected to the reset input terminal R of FF91.

As shown in FIG. 10, for example, an appropriate number of variable prize winning devices A according to this invention configured in this manner are arranged in the gaming section 102 surrounded by the guide rail 101 of the pachinko machine 100 (in the figure, 2 left and right). 103 is the center winning device, 1
04 is an out hole. The control devices 8 and 9 are arranged at appropriate locations on the back side of the game board of the pachinko machine 100. Arrows connecting the control devices 8, 9 and the variable prize winning device indicate the flow of signals.

Now, suppose that the ball hit by the player enters the first winning hole 27, the detection signal from the detector 6 sets, for example, FF81 of the control device 8 shown in FIG. 8, and the solenoid 5 is energized. Ru. As a result, the rotating receiving frame member 2 rotates 90 degrees as described above, and the second prize opening 28 appears as shown in FIG. Since this second winning hole 28 maintains a state where the winning rate is high for one cycle of the ring counter 85 of the control device 8, there is a possibility that the hit balls will win one after another during that time. Furthermore, if the control device 9 shown in FIG. 9 is adopted, a fixed number of winning balls, for example, 10 winning balls, can be guaranteed regardless of the time after the second winning hole 28 appears. Note that these control devices 8 and 9 are merely examples, and by employing control devices having other control modes, the winning rate can be further changed.

In addition, although a solenoid is used as the electrical drive means of the variable prize winning device A according to this invention, the invention is not limited to this, and electric drive means such as a motor or a rotary solenoid may be used. . When these rotational drive means are used, unlike the case of the solenoid described above, there is no need for a mechanism for converting linear motion into rotational motion, and there is an advantage that the back side mechanism can be simplified.

As described in detail above, according to the variable winning device according to this invention, the normal first winning hole that is difficult to accept batted balls and the detector that detects the winning ball that has entered the first winning hole are installed in the variable winning device itself. Based on this detection signal, the control device operates the electric drive means to convert the rotating receiving frame member, thereby causing a second winning hole that can easily receive the batted ball to appear. The rotating receiving frame members can be individually converted based on the winning balls themselves that have won in the device itself. Therefore, this variable winning device can be used alone without being combined with other winning devices, and can significantly increase the interest of the game. Unlike conventional methods, the movement is quick and reliable, and there is no instability factor at all, and all the drawbacks that commonly occurred in the past, such as unexpected closing of the blades, jamming, or poor opening, can be overcome. It is.

In addition, since the variable part of the winning device and its driving device are integrally and compactly mounted on the board, there is no connection between the front and back sides, which was troublesome in conventional assembly, and the mounting holes provided on the game board can be easily mounted. It can be assembled into a pachinko machine by simply inserting it from the front, simplifying the work.

In addition, by controlling the electrical drive means in various ways with the control device, the winning rate can be varied in various ways, and the winning rate can be varied in many ways compared to the conventional system, which involves repeating monotonous operations. equipment can be provided.
