Description

Detailed Description of the Invention The present invention connects an upper tray provided on the front side of a pachinko machine and a prize ball discharge device provided on the back side of a game board by a prize ball discharge gutter, and This invention relates to an improvement of a pachinko machine in which a bell faces into a ball ejecting gutter and a prize ball ejecting sound effect is generated by hitting the bell with balls flowing down in the gutter.

2. Description of the Related Art Pachinko machines are conventionally known in which a bell is provided in a prize ball discharge gutter to generate a prize ball discharge sound effect. However, in the conventional system, the bell was simply placed in the middle of the length of the prize ball discharge gutter so that it protruded into the gutter, so when the prize ball collided with the circumferential surface of the bell, the bell could be irregularly disposed. There is a risk that the ball may bounce back and cause a ball jam, or it may bounce back forcefully by the bell, accelerating the downward speed of the winning ball, causing it to crash into the upper tray from the downstream end of the prize ball discharge gutter and bounce out of the upper tray. Ta.

Therefore, in the present invention, each mechanical part is overlapped in the front and back direction of the game board, and the prize ball discharge gutter is formed into a guide path whose upper side faces the prize ball discharge device and has a treadle in a part, and an open lower end of the guide path. and a connecting path that bends forward from the top and penetrates the game board, and the inclined lower end of the connecting path is directed toward the prize ball outlet of the upper tray on the panel surface provided in the front frame, and the guide path The ball is characterized by a bell facing the prize ball which collides with the prize ball flowing down the guide path to reduce the downward force and change the direction of the ball so that the prize ball faces the connecting path.

Therefore, according to the present invention, each mechanical part can be consolidated and the strength can be improved, and since the direction of flow of the prize ball that collided with the bell is specified,
The prize balls that collided with the circumferential surface of the bell and bounced back smoothly flowed down toward the connecting path, preventing balls from clogging in the guide path of the prize ball discharge gutter, the connecting path, and the bend between the two paths. It can be prevented. In addition, when the prize ball flowing down the guide path collides with the bell, the downward force will be reduced, so when flowing down the guide path, the speed of the prize ball should be made sufficiently high so that it collides with the bell forcefully. The sound effect generated can be made louder, and even if the falling speed of the prize ball is increased, if it collides with the bell, the falling speed of the prize ball will be slowed down, so the prize ball that has flowed into the communication path will be able to flow through the prize ball outlet. It is possible to prevent the object from jumping out of the upper tray by forcefully entering the upper tray.

I'm going to meet you.

The mechanism board 7 is made of, for example, a transparent plastic board, and a prize ball collection gutter 40 and a prize controller 41 are provided on the surface facing the back surface of the game board 6, that is, the surface constituting the second space 9. The winning ball collection gutter 40 is separated from the mechanism board 7 and installed on the game board 6 as shown in FIG.
It may be attached directly to the back surface of the mechanism plate 7, or it may be formed integrally with the mechanism plate 7. This winning ball collection gutter 40 is
It collects the winning balls led out to the back side of the game board 6, has a front-rear width that allows the winning balls to flow down, wide horizontal width, and a slightly inclined bottom part 42. and an inclined lower end opening 42' of the bottom portion 42.
is provided with a prize controller 41 for controlling the collected winning balls to be sent to one ball, and below the opening 42', as shown in FIG. 8, the winning balls controlled by the winning ball controller 41 are discharged. Operating gutter 4 guided to operating section 43
The inlet 44' of No. 4 is opened.

Therefore, the ball fired by the player is in the gaming section 38.
When the ball enters the winning hole 39 while flowing down, the ball is discharged to the back side of the game board 6 and is collected by the winning ball collection gutter 40 as a winning ball. When the winning ball flows into the winning ball controller 41 from the opening 42' of the winning ball recovery gutter 40, the winning ball controller 41 tilts due to the weight of the winning ball, and the winning ball is transferred to the operating gutter 4.
4 and stop. Note that when the winning ball controller 41 communicates with the operating gutter 44 and stops, the controller 41
Since the stop piece 41' provided above the tip of the controller 4 closes the opening 42', even if a plurality of balls enter the prize continuously, the controller 4
1 supplies the winning ball to the operating gutter 44 while controlling it to one ball. The operating gutter 44 consists of a guide section 44a provided in the front surface of the mechanism plate 7, that is, the second space 9, and an operating section 44b provided vertically in the rear surface of the mechanism plate 7, that is, the third space 10. 44a and actuating part 44b
communicates through the mechanism plate 7, and an operating lever 46 of a prize ball ejecting actuator 43 that operates a prize ball ejecting device 45 faces into the actuating portion 44b. Therefore, when a winning ball flows into the operating gutter 44, the winning ball flows down inside the guide portion 44a on the front side of the mechanism plate 7.
After passing through the mechanism plate 7, it flows into the operating portion 44b and rests on the ball mounting portion 46' of the operating lever 46.
When a winning ball is placed on the ball mounting portion 46', the operating lever 46 is tilted by the weight of the ball, and the winning ball ejecting device 45 is operated via the connecting rod 47 and the like. The ball that descends while tilting the operating lever 46 is stopped by the blocking piece 48 from flowing down until the prize ball is ejected from the lower part of the operating portion 44b.

On the other hand, on the back surface of the mechanism plate 7, that is, the surface constituting the third space 10, a storage tank 49 for storing prize balls is provided in the upper part, as shown in FIG. An inlet 50a of a ball ejecting gutter 50, which ejects balls while arranging them in two rows, is located below the ball ejecting port 49' opened in , and an outlet 50b of the ejecting gutter 50 communicates with the prize ball ejecting device 45. . Further, a treadle lever 51 connected to the stopping device 25 is pivotally attached to the bottom of the ball guiding gutter 50 near the upper end of the slope, and a ball shortage detector 52 is attached to the treadle lever 51.
will be established. Therefore, if there are not enough balls in the storage tank 49 and the tread lever 51 rises, the stopping device 25
stops firing balls and changes the pachinko machine to the launch state, and at the same time the ball shortage detector 52 turns on and balls are fed into the storage tank 49 from a ball supply device (not shown) installed above the pachinko machine 1. Can be replenished. Further, a ball extracting mechanism 53 is provided at the bent end 50c of the ball guiding gutter 50, and the ball extracting mechanism 5
A ball extraction gutter 54 is extended downward from 3, and by opening the ball extraction mechanism 53, the balls in the storage tank 49 can be extracted.

The prize ball ejecting device 45 operates when a batted ball enters the winning hole 39 and forms a winning pattern, and discharges a number of prize balls corresponding to the winning pattern into the upper tray 21 or the lower tray 11 on the front of the pachinko machine. A tilting gutter 55 capable of storing a certain number of balls inside is pivotally attached to the back surface of the mechanism plate 7 so as to be freely tiltable.
5 to the outlet 50b of the ball outlet gutter 50,
The outlet 55b of the tilting gutter 55 faces the inlet 56a of the prize ball ejecting gutter 56, and is connected to the prize ball ejecting unit 43 via the connecting rods 47.

Therefore, when a sufficient amount of balls is supplied into the storage tank 49, the balls are transferred from the ball outlet 49' to the ball outlet gutter 50.
While flowing down, the balls line up and flow into the tilting gutter 55 of the prize ball ejecting device 45. The tip of the ball that has flowed into the tilting gutter 55 is the outlet 55b of the tilting gutter 55.
It stops when it hits the stopper 57 facing the tilting gutter 5.
A certain number of balls, for example 15, are waiting in the box. When a hit ball enters a prize and the operating lever 46 of the prize ball discharge operating section 43 is tilted, the tilting gutter 55 is tilted via the connecting rods 47. When the tilting gutter 55 tilts, the balls inside flow down into the prize ball discharge gutter 56.

The prize ball discharge gutter 56 guides the balls flowing down from the prize ball discharge device 45 to the upper tray 21 or the lower tray 11 at the front of the pachinko machine, and is generally composed of an upright vertical portion and a gently downwardly sloping horizontal portion. It consists of an L-shaped guide path 58 and a connecting path 59 that is bent at a substantially right angle from the inclined lower end of the guide path 58 and extends forward. The communication path 59 passes through the mechanism plate 7 and connects to the second
It traverses the space 9, its tip faces a hole 6' formed in the game board 6, and its sloping lower end connects to the entrance 32' of the connecting gutter 32 described above. In addition, when a winning ball passes through the inclined upper bottom of the lateral part of the guide path 58, it rotates downward to restore the winning ball controller 41 and prevent the blocking piece 48 from rotating downward.
A step board 60 is provided to raise the height, and a switching valve 61 is provided downstream of the step board 60. And the switching valve 61
An outlet 62' of an overflow gutter 62 extending downward from the guide gutter 13 faces an inlet 13' of the guide gutter 13 and communicates with the lower tray 11. As shown in FIGS. 9 to 12, the bent portion 63 where the guide path 58 and the communication path 59 bend at a substantially right angle is formed by sloping the bottom surface 59' of the communication path 59 downward at a steep angle. In addition, a bell installation space is formed by cutting out the inclined upper part of the bottom surface 59' and a part of the side wall of the communication path 59, and the bell 64 is installed in the space with a support rod 65.
Supported by. The support rod 65 is a thin plate bent into a crank shape, and its base end 65a is fixed to the inner surface of a back cover 66 formed by extending the side wall of the guide path 58, and the bell 64 is fixed to its tip 65b. The bell 64 has a bowl-like or hemispherical shape, and when the tip 65b is fastened to the center of the inner surface with a screw 67, it is fixed so that a part of the surface faces the bent portion 63.

When the bell is fixed in this manner, the center position O of the bell will be higher than the line l extending from the bottom surface 58' of the guide path 58 by a height H. Since the diameter of the pachinko ball is 11 mm, this height H is preferably about 5.5 to 10 mm. In addition, when the bell is in the fixed state, a gap D is formed between the side surface of the bell 64 facing into the bent portion 63 and the inner surface of the communication path 59 (in particular, the inner surface of the side wall 59''), and the gap D is Set the width to at least twice the diameter.

By forming the head C in the bent portion 63 in this way, and by forming the height H and the gap D in the attached state of the bell 64, the flow of prize balls in the prize ball discharge gutter 56 becomes smooth and light. It is possible to generate sound effects.

That is, the balls discharged from the prize ball discharge device 45 flow down the guide path 58 of the prize ball discharge gutter 56, and during the flow, the treadle 60 is tilted to restore the prize ball controller 41,
At the same time, the blocking piece 48 is raised to release the winning balls stopped in the operating gutter 44 to the outside. The ball guided to the inclined lower end of the guide path 58 collides with the circumferential surface of the bell 64 as it flows down the bend 63. At this time, as described above, since the center position O of the bell 64 is located slightly above the extension line l of the guide path 58, most of the balls that have left the inclined lower end of the guide path 58 are located at the center position O of the bell 64. The ball collides with force at almost the same height as the ball, producing a loud, clear and light ball ejection sound effect.

On the other hand, since the circumferential surface of the bell 64 is inclined in an arc toward the connecting path 59, the ball that collides with the circumferential surface of the bell 64 and bounces off the surface of the bell 64 will fall downward when it collides. At the same time, most of the flow direction is changed at right angles toward the communication path 59. Therefore, the ball oriented toward the connecting path 59 flows into the connecting path 59 and reaches the bottom 59'.
The ball flows down along the slope of the ball and is smoothly discharged into the upper tray 21 through the prize ball discharge port 31.

In order to increase the volume of the bell 64 in this way, it is advantageous not only to make the collision position between the ball and the bell 64 appropriate, but also to have a strong momentum of the ball that collides with the bell 64. If the downward force is too strong after the collision, the ball may enter the upper tray 21 from the prize ball outlet 31 and jump out of the upper tray 21 with great force. Therefore, in the present invention, by positioning the circumferential surface of the bell 64 on the bent portion 63 with an inclination as described above,
Reduces the downward force of the ball when it collides with the bell 64,
Moreover, the flow direction is changed so that the prize balls are smoothly discharged to the upper tray 21. Further, in the illustrated embodiment, the bell 64 is attached to the upper tray 21.
Since the bell 64 is located close to and facing the prize ball discharge port 31, not only can the amount of attenuation of the sound effect generated by the bell 64 be extremely reduced, but also the prize ball can be delivered to the upper tray 21 almost at the same time as the sound effect is generated. can be discharged.

In addition, when a large number of batted balls enter prizes in a short period of time and a large number of prize balls are generated, when the upper tray 21 is filled with prize balls, the overflowing balls become stagnant in the prize ball discharge gutter 56, and the weight of the balls The switching valve 61 is opened. In this way, when the switching valve 61 opens, the guide path 58 of the prize ball discharge gutter 56 and the lower tray 11 communicate with each other via the overflow gutter 62. Therefore, the balls flowing down from the prize ball ejecting device 45 into the prize ball ejecting gutter 56 tilt the treadle 60, flow into the overflow gutter 62 through the open switching valve 61, and pass through the guide gutter 13. and is discharged from the lower tray 11.

As explained above, according to the present invention, each mechanical part is formed by overlapping in the front-rear direction of the game board, and the prize ball discharge gutter formed by overlapping is connected to a guide having a step board in a part with the upper side facing the prize ball discharge device. and a connecting path that bends forward from the open lower end of the guide path and penetrates the game board, and the prize ball in the upper saucer on the panel surface has the inclined lower end of the connecting path provided in the front frame. Directed toward the discharge port, the guide path is provided with a bell that collides with the prize balls flowing down the guide path to reduce the downward force and change the direction of flow so that the prize balls face the communication path. Therefore, it is possible to consolidate each mechanical part and improve the strength, and by increasing the downward force of the prize ball flowing down the guide path and colliding with the bell with force, the volume of the sound effect generated can be increased. In addition, since the bell is located close to the prize ball discharge port of the upper tray, the amount of attenuation of the generated sound effect can be extremely reduced, resulting in high efficiency. It is possible to provide a pachinko machine which allows players to enjoy the game at a good pace and in an exhilarating manner by playing the games almost simultaneously.

Furthermore, even if the downward force of the prize ball flowing down the guide path is strong, the downward force is reduced by the prize ball colliding with the bell, and moreover, the downward direction is changed by this bell so that it heads toward the guide path. Therefore, it is not only possible to prevent balls from clogging in the prize ball discharge gutter, but also to prevent prize balls from rushing out of the upper tray by entering the upper tray from the prize ball discharge port, The prize ball can be smoothly discharged to the upper tray.
