Description

[Detailed explanation of the invention] This invention relates to a ball winning device for a pachinko machine.
In particular, the present invention relates to a hit ball winning device that is characterized by changing from a state with a low winning rate to a state with a high winning rate by moving an obstacle nail.

Conventional batted ball winning devices have a pair of batted ball guide walls made of synthetic resin placed above the winning slot, and when a ball hit by a player enters a specific winning slot, the batted ball guide walls move to increase the winning amount. It had come to constitute a winning opening with a high rate of winning. However, placing a large number of such synthetic resin ball guide walls in a limited gaming area feels cramped, and since the ball guide walls are made of synthetic resin, winning balls may not hit the wall. However, the bounce was simple, and it was very uninteresting for players.

This idea was devised in view of the above points,
A plurality of obstacle nails protruding from the front surface of the base plate corresponding to each of the long holes are planted on the back side of a base board that is attached to a gaming section in which a prize opening and slotted holes located on the right and left upper sides of the winning opening are formed. A rotating plate which is attached to the base plate and rotatably pivoted to the base plate and a drive device for operating the rotating plate are integrally disposed, and the obstacle nail is moved by the drive device. The present invention is characterized in that the front surface of the base plate is movable in order to provide a second state in which it is easy for a batted ball to win a prize from a first state in which it is difficult for a batted ball to enter a prize opening.

This invention will be explained below based on the embodiments shown in the drawings.

Figure 1 is a front view of a pachinko machine equipped with a ball winning device based on this invention, and shows the game board 1 of pachinko machine A.
A game section C surrounded by a guide rail B is constructed, and the game section C includes a ball winning device D according to this invention, an appropriate obstacle nail E (partially shown), a specific winning hole F, and an out hole G. etc. are provided. H is a supply tray for pachinko balls, I is a tray that receives prize balls when they overflow the supply tray H, and J is an operation dial for adjusting the strength of the ball by its rotation. .

Figure 2 and below are the ball winning device D based on this invention.
(hereinafter referred to as winning device D), and the embodiment shown in FIGS. 2 to 4 will be described in detail below.

A cutout 2 is provided at a location on the game board 1 where the winning device D according to this invention is attached, and a rectangular base plate 3 is fixed to the front surface of the game board 1 corresponding to the cutout 2. A prize opening 4 is opened in the lower central part of the base plate 3, and a receiving plate 5 is fixed to the lower edge of the winning opening 4. The receiving plate 5 is oriented diagonally upward toward the tip, so that the ball will surely enter the winning hole 4. A solenoid 6 is integrally attached to the back surface of the base plate 3 at a location corresponding to the upper part of the winning opening 4. When the solenoid 6 is energized by electricity from a control device 70, which will be described later, the actuator 7 moves upward in FIG. 2 while compressing a return spring 8. A long groove 9 is bored in a suitable location (in the upper part in the figure) of the actuator 7, and a slide pin 11 embedded in a boss 10 on the back of the base plate 3 is loosely fitted into this long groove 9 to allow movement of the actuator 7. are now being guided. Further, a slide plate 12 is integrally attached to the actuator 7 in a direction perpendicular thereto. When the power to the solenoid 6 is cut off and the solenoid 6 is deenergized, the long groove 9 of the actuator 7 is guided by the slide pin 11 and moves downward by the elasticity of the return spring 8.
The state shown in FIG. 2 is maintained. 1
3 and 13' are a pair of rotating plates that are almost L-shaped.
A plurality of obstacle nails 14, 14', which are pins (metal pins, synthetic resin pins, metal pins whose surfaces are coated with synthetic resin, etc.), are arranged at equal intervals in the vertically extending part. (The figure shows a state in which 10 tubes, 5 tubes each, are planted on the left and right rotating plates 13 and 13'). A pair of rotating plates 1
3 and 13' are arranged symmetrically on the back of the base plate 3 as shown in FIG.
Obstacle nails 14a and 14a' installed in the places where the rotation plates 13 and 13' are bent at right angles among the rotation plates 13 and 14' are used as rotation axes, respectively, and the base plate can be rotated freely around these nails. It is attached to 3. A pair of rotating plates 13, 13' are rotating shafts (obstruction nails) 14
Since the other obstacle nails 14, 14' rotate about the rotation axes 14a, 14a', they also move in a circular arc trajectory about the rotation axes 14a, 14a'. In order for the obstacle nails 14, 14' to protrude from the front surface of the base plate 3, a plurality of elongated holes 15, 15' are bored in the base plate 3 at locations corresponding to the obstacle nails 14, 14'. Reference numeral 15 denotes an arc-shaped elongated hole whose center of curvature is the rotation axis 14a, 14a' over the range of circular motion of the obstacle nails 14, 14' so as not to impede the arcuate movement of the obstacle nails 14, 14'. It is becoming. 1
6 and 16' are double return springs whose one end is fixed to the base plate 3, and the other end is fixed to the rotating plates 13 and 13', respectively, and their elasticity normally causes the rotating plate 1 to
3 and 13' are maintained in the state shown in FIG.
Further, one end of each of the pair of rotating plates 13, 13' extending in the horizontal direction is locked to both ends of the slide plate 12. Therefore, when the slide plate 12 moves in the direction of the arrow in FIG.
It rotates about a, 14a' as shown by the arrow while pulling the return springs 16, 16'. In addition, the obstacle nails 17 are fixed obstacle nails planted in the base plate 3 above the winning hole 4, and in the figure, six nails are planted, three on the left and right, with the minimum interval l for the ball to flow down. has been done.

The ball winning device D according to this invention is configured as described above, and when a ball hit by a player enters a specific winning hole F, for example, the solenoid 6 is energized. It is characterized by a state in which the winning rate is high. That is, when the solenoid 6 is energized by a control device 70 to be described later, the slide plate 12 together with the actuator 7 presses the return spring 8 while moving the elongated hole 9 and the slide pin 11.
The obstacle nails 14, 14' move upward under the guidance of the sliding plate 12, and together with the pair of rotating plates 13, 13', the obstacle nails 14, 14' are rotated to a state with a high winning rate as shown in FIG. It rotates around the moving shafts 14a and 14a'. The state shown in FIG. 3 when the obstacle nails 14, 14' have finished rotating is that the left and right obstacle nails 14, 1
4' are arranged in an inverted C shape to form a guide wall for the batted ball, and if the batted ball falls within the range of the upper interval L, it will be guided by the left and right obstacle nails 14, 14' and enter the winning hole 4. The winning rate is extremely high because it is guided by the following. After a certain period of time has elapsed, the power to the solenoid 6 is cut off and the solenoid 6 is deenergized, so the sliding plate 12 moves downward by the elasticity of the return springs 8, 16, 16', and the rotating plates 13, 13' return to their original positions. Due to the elasticity of the springs 16, 16', the obstacle nails 14, 14' rotate in the opposite direction, returning to the state shown in FIG. In the state shown in FIG. 2, the obstacle nails 14, 14' are arranged parallel to each other in two vertical rows on the left and right with respect to the prize opening 4, and the interval is sufficiently widened (i.e., the left and right obstacle nails 14, 14'' are placed at the distance L), the winning balls must be directly entered into the winning hole 4 through the distance l between the fixed obstacle nails 17, resulting in an extremely low winning rate.

5 to 7 show a second embodiment, in which the pair of rotary plates 13, 13' have a circular arc portion and a straight line extending from approximately the center of this arc portion to the center of curvature of the arc. Rotating pins 18 and 18' are each provided at one end of the straight part, that is, a location corresponding to the center of curvature, and the pair of rotating plates 13 and 13' Moving pin 1
It is designed to be able to reciprocate and rotate relative to the base plate 3 about 8 and 18'. A plurality of obstacle nails 14,
14' are planted in an arc shape at equal intervals, and the rotation plate 1
3 and 13', it reciprocates and rotates. Obstacle nail 1
4 and 14' protrude from the front surface of the base plate 3 in the same way as in the embodiment described above, and since they rotate reciprocatingly, the base plate 3 is provided with screws so as not to impede the reciprocating rotational movement of the obstruction nails 14 and 14'. A pair of arc-shaped elongated holes 15, 15' with the rotation pins 18, 18' as centers of curvature are bored on the left and right sides over the movement range. A link piece 19 is attached to the tip of the actuator 7 of the solenoid 6, and one end of a rotating lever 21 that swings and rotates about a shaft 20 fixed to the base plate 3 is attached to the tip of the link piece 19. has been done. Also, there are interlocking rods 2 at both ends of the rotating lever 21.
2, 22' are each pivoted, and each interlocking rod 22,
At the other end of 22', rotary stays 23, 23' (integrated with rotary plates 13, 13' at rotary pins 18, 18') are pivoted by pins etc. to form a link mechanism. is configured.

In the state shown in FIG. 5, the arrangement of the obstacle nails 14, 14' is such that the distance l is the minimum for the ball to flow downward.
The winning rate is relatively low. Next, for example, when the batted ball enters the special winning hole F, the solenoid 6
When the lever is energized, the link piece 19 in the figure moves to the left due to the driving force, and the rotating lever 21
rotates counterclockwise about axis 20. As a result, the interlocking rod 22,
The rotating plates 13, 13' connect to the rotating pin 1 via 22'.
8, 18' to the state shown in FIG. In the state shown in FIG. 6, the obstacle nails 14, 1
The arrangement of the holes 4' is changed into an almost inverted V-shape, forming a large receiving opening with a distance L sufficient for hitting a ball to win a prize, resulting in an extremely high winning rate. Incidentally, the falling ball is hit by the minimum distance l between the obstacle nails 14, 14'.
It will surely fall onto the receiving plate 5 because it will be guided by
Moreover, since the receiving plate 5 is tilted upward with respect to the winning hole 4, the hit ball is directly introduced into the winning hole 4 and becomes a winning ball.

8 to 10 show a third embodiment. A fixed obstacle nail 17 is installed on the base board 3 in a V-shape above the prize opening 4, and further above that obstacle nails 14, 14' are configured to be movable in the horizontal direction. . The obstacle nails 14, 14' are attached to the slide plates 24, 24' while passing through them, and the slide plates 24, 24' are attached to the base plate 3.
The long grooves 26, 26' are loosely fitted into the slide pins 25, 25' fixed to the slide pins 25, 25'.
It can be moved horizontally using guide 5'. That is, four left and right slide plates 24, 2 are provided on the back side of the base plate 3, two on the left and two on each side.
4' are pulled together by return springs 16, 16' whose ends are locked to a pair of upper and lower obstacle nails 14, 14', respectively, and one ends of the long grooves 26, 26' are connected to the slide pins 25, 25. ' is in contact with . A cam plate 28 having inclined cam surfaces 27, 27' on the left and right is attached to the actuator 7 of the solenoid 6, and these cam surfaces 27, 27' contact the obstacle nails 14, 14', and the inclined cam surfaces The obstacle nails 14, 14' are moved in the horizontal direction. The cam plate 28 indicated by a solid line in FIG.
It shows the position when it is energized. When the solenoid 6 is de-energized, the cam plate 28 is pulled upward by the return spring 8 (tension spring), and the obstacle nails 14, 14' are pulled together by the return springs 16, 16', preventing the ball from being hit. There is a minimum distance l for the flow to flow down. When the solenoid 6 is energized, the cam plate 28 moves downward as shown by the arrow, and the inclined cam surfaces 27, 27' resist the elasticity of the return springs 16, 16' and slide together with the four obstructing nails 14, 14'. The plates 24, 24' are moved horizontally. As a result, the obstacle nails 14, 14' are expanded in an inverted V-shape along the cam surfaces 27, 27', forming a large receiving opening with a distance L sufficient for the ball to flow down, and winning the prize. The rate is extremely high. If the falling ball is within the interval L, the ball is guided by the guide wall made up of the obstacle nails 14, 14' and the fixed obstacle nail 17, and is caught on the catch plate 5, winning a prize. Win 4th place.

Finally, the control device 70 for controlling the energization of the solenoid 6 will be explained. The control device 70 turns on the solenoid 6 continuously or intermittently for a certain period of time based on a signal from a specific winning ball detection switch 71 (not shown), which is a micro switch or the like attached to the rear of the specific winning hole F. Any suitable material may be used as long as it can be used, and various known materials can be used. An embodiment of the control device 70 is shown in FIG. The control device 70 includes a differentiation circuit 72, a timer circuit 73, an AND gate 74, and a pulse oscillator 7.
5. Consists of a driver circuit 76. In this embodiment, when the specific winning ball detection switch 71 detects a winning ball entering the specific winning hole F, the timer 73 derives a high level signal for a certain period of time and is given as one input to the AND gate 74. The AND
A signal from a pulse oscillator 75 (the pulse period is selected so that the winning device D opens and closes only once with one pulse) is applied to the other input of the gate 74. The driver circuit 76 is intermittently turned on and off based on the output of the AND gate 74.
As a result, the solenoid 6 is intermittently energized and the winning device D is repeatedly opened and closed for a certain period of time set by the timer 73. Incidentally, if it is sufficient to simply open the winning device D for a certain period of time without performing intermittent opening/closing operations, the AND gate 74 and the pulse oscillator 75 can be omitted, resulting in an extremely simple control device.

Although we have explained the case where a prize is won in the specific winning hole F, this is just an example. For example, after counting a certain number of winning balls, the winning device D can be changed from the first state with a low winning rate to the first state with a high winning rate. 2, or when the batted ball passes through a specific area of the gaming section C, the control device 70 activates the winning device D when a predetermined condition is satisfied.
All you have to do is activate it.

In any of the embodiments described above, the obstacle nail 1
Changing the movement (fluctuation) range of 4, 14′,
By changing the energization time of the solenoid 6 and the settings of the control device 70, the winning rate can be varied in various ways.

As described in detail above, this idea is such that a pair of rotating plates are rotatably provided on the left and right sides of the back side of the winning opening, and obstacle nails are planted in the rotating plates, and a driving device is used to drive the rotating plates together with the rotating plates. Since the nail is configured to be movable, it can be easily changed from the first state where the winning rate is low to the second state where the winning rate is high by operating the drive device.

In this invented ball winning device, instead of the conventional ball guide wall made of synthetic resin, the guide path to the winning hole is made up of a plurality of movable obstacle pins. The ball hits movable obstacle pins (pins) and bounces to win a prize, which is unprecedented. It can be increased a lot.

Further, since a specific winning mode can be arbitrarily set, it is possible to diversify the game contents.

Furthermore, the ball winning device according to the present invention can be attached to a desired location in the gaming section and the flow path of the ball can be changed by changing the spacing between the nails, making it possible to use it in combination with other winning devices. The game content can be diversified.

Furthermore, according to this invention, the guide path to the prize opening is formed with a row of pins made of metal or synthetic resin, rather than the conventional integrated guide wall made of synthetic resin that easily gets dirty, so it can be used for a long time. It also has the advantage of being less likely to attract dirt and stains.
