Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a variable winning device having a large variable winning opening in a pachinko game machine, and in particular, a pair of variable winning devices arranged on both sides of the large variable winning opening. This invention relates to a large-scale variable winning device that has three-dimensional and optical decorations.

[Conventional technology]

First, an outline of a conventional pachinko machine equipped with a large-scale variable winning device 19 will be explained with reference to FIG. In the figure, 1 is the main body of the pachinko machine, 2 is the front frame of the machine, 3 is the game board that is fixed from the back side into a large window hole in the center of the front frame, and 4 is attached to the periphery of the window hole in the front frame. The metal frame 5 is a guide rail made of a band-shaped metal plate for regulating the passing area of pachinko balls on the game board, and the game area 6 surrounded by the guide rail in a circular shape has a mechanism that determines the winning probability by opening and closing operations. Variable winning devices 7a, 7b and a plurality of winning devices 8, which can be changed, are provided. Reference numeral 9 is a winning ball indicator provided at the upper left of the game board, which notifies the player of the occurrence of winning balls in the aforementioned various winning devices by lighting a lamp, and 10 is a stop indicator, which indicates that the scheduled number of winning balls has been received. Upon discharge, the end of the game is notified by lighting a lamp.

Reference numeral 17 denotes an operation handle for firing pachinko balls, which is used to fire the pachinko balls that are sent one by one from the downstream side of the supply tray 12 to the firing section 14 when the base plate 13 is closed. A receiving tray 18 is fixed to the lower part of the front frame 2, and is used to receive Pachinko balls that are subsequently discharged when the supply tray 12 is full of prize balls.

The component board 11 of the large variable winning device 19 has a horizontally elongated opening 11 that can receive a plurality of winning balls at the same time.
A (so-called large variable prize winning hole) and openings 11B located on both sides thereof and capable of receiving one winning ball are provided. When a pachinko ball enters at least one of the openings 11B, a micro switch provided near the back of the opening 11B is activated, and the roulette device 15 provided on the game board 3 starts operating. Then, what is the game result of the roulette device 15 (generally all numbers are "7"?
A specific game mode will occur depending on the case where the above conditions are met.
When a specific game mode occurs, an electromagnetic solenoid provided on the back side of the game board 3 is energized, and this energization causes the horizontally long opening 11A to be opened for a relatively long time (for example, 30 seconds), which greatly increases the winning probability. A high state will occur.

The opening 11B is formed by an enclosing frame 20, and the enclosing frame 20 is usually entirely composed of a colored transparent member, and an illumination lamp, a light emitting diode, etc. are disposed inside the enclosing frame 20, and the enclosing frame 20 is turned on when the aforementioned specific game mode occurs. Or it is configured to blink. However, conventional devices simply emit light, lack decorative considerations, and do not enhance the interest of pachinko games.

[Problem that the invention attempts to solve]

In other words, in conventional pachinko machines, when a specific game mode occurs, light is simply emitted from the surrounding frames placed on both the left and right sides of the large variable prize opening, and a pair of lights are displayed. The pachinko balls that flow between the enclosing frames and enter the large variable prize opening 11A are not sufficiently illuminated, and the decorative effect that can further enhance the sense of joy that a specific game mode is occurring is not necessarily achieved. I can say that I was exhausted.

The present invention solves this drawback of the prior art, and first of all, the surrounding frame itself is not only decorated with a three-dimensional double structure on its front side, but also decorated with a multicolored light diffused from its outer periphery. A large variable winning pachinko machine capable of decorating the enclosing frame and colorfully illuminating falling balls around the enclosing frame, thereby further heightening a player's feeling of joy when a specific game mode occurs. It provides equipment.

[Means for solving problems]

In the present invention, the surrounding frame arranged on both sides of the large variable prize opening is mainly composed of a first colored transparent member, and a diamond cut part is provided on the back side of the frame, and the front side or A second colored transparent member is polymerized from the rear surface to form a three-dimensional double structure, and the first
By providing a light diffusing portion having a micro-triangular cross section, a lenticular lens, a Fresnel lens, etc. on the outer periphery of the colored transparent member, the first
As shown in Figure 2, the winning channel X is defined between the surrounding frames 20 arranged on both sides of the large variable winning opening.
The pachinko balls flowing down are effectively illuminated and decorated by light emitted from the light diffusion section of the surrounding frame.

〔Example〕

FIG. 1 is a perspective view showing an embodiment of the present invention, in which a large variable prize opening 1 provided on a component board 11 is shown.
1A (open state) and the appearance of winning a prize openings 11B provided on both sides thereof are shown. The surrounding frame 20 provided on both sides of the large prize opening 11A can be removed from the component board 11 by removing the mounting screws 22, and the structure of the removed surrounding frame 20 is shown in FIGS. 2A and B. shown. That is, the surrounding frame 20 is preferably molded using plastic material, and the upper part thereof is cut out to form a prize opening 11B capable of receiving one winning ball.
A first colored transparent member 20A and a second colored transparent member 20B are disposed on the front surface of the surrounding frame 20, and the back surfaces thereof are provided with a diamond cut D having a surface area expansion effect and a diffused reflection effect. Alternatively, it can reflect or transmit light from the outside in a variety of ways to enhance the glittering decorative effect. The second colored transparent member 20B is the first colored transparent member 20B.
An opening 20 having a similar shape provided in a part of A
It is fitted and glued into H from the front or back. Therefore, the second transparent member 20B is superposed on the first transparent member 20A to achieve a three-dimensional double structure. The size and direction of the diamond cut,
First colored transparent member 20A and second colored transparent member 20
By making them different from B and in addition to this, by using transparent members of different colors, it is possible to achieve a decorative effect by further diffusing light and harmonizing the colors with the colored transparent members of multiple colors. You can increase it further. First colored transparent member 20
As shown in FIG. 2B, a front decorative plate 21 with a recess 21b is attached to the upper half of the front surface of A by adhesive or other means, and a seal is placed in the recess 21b for the purpose of increasing decoration. Pasting and coloring are done.

Outer peripheral portions 20C, 20D and 20 of the surrounding frame 20
E is provided with a light diffusing section (to be described later) on its inner surface, so that light from a lamp (to be described later) provided inside the surrounding frame 20 is refracted in various ways by this light diffusing section. Light is emitted outward from 20D and 20E in various directions, and as with the first and second colored transparent members 20A and 20B provided on the front surface of the surrounding frame 20, the decorative effect of the light can be enhanced.

FIGS. 9A and 9B show the enclosing frame 20 shown in FIG.
They are an enlarged perspective view and a cross-sectional view of, for example, 20C among the outer circumferential parts 20C to 20E. The outer surface of the outer circumferential portion 20C is a flat surface, and the inner surface thereof has a slit structure in which a large number of triangular prisms each having a substantially triangular cross section are lined up. According to such a configuration, the incident light beams G1, G2, G emitted from the light source lamp 43
3 is the refracted light R that enters from the slope of the triangular prism.
1, R2, and R3 in various different directions.

Next, FIG. 10 shows the configuration of a lenticular lens that is effective when applied to the outer peripheral portion 20C. This lenticular lens can be used not only in the outer circumferential portion 20C but also in 20D and 20E. FIG. 10B shows the appearance of this lenticular lens, which has the outer shape of a so-called semicylindrical microlens group, and its longitudinal section is shown in FIG. 10A. Since no curved surface is formed in the X-axis direction shown in FIG. 10B, it has no refractive power for light;
In the Y-axis direction (the direction in which the ball falls), each of the many lenses has a spherical surface, so that the transmitted light is refracted by the lens action. Lenticular lenses (for example, L1 to L3) in the outer peripheral portion 20C and the light source lamp 4
If the lenticular lens 20C is designed so that the distance between the two lenses, that is, D1, D2, and D3, is equal to the focal length of each lens L1, L2, and L3, the transmitted light R1, R2, and R3 The light is emitted as parallel rays in either direction. Therefore, the ball falling through the winning channel X between the surrounding frames 20 will be illuminated over a wide range. That is, the pachinko balls begin to be illuminated well before they reach the winning channel X between the surrounding frames 20, and are illuminated with strong light until they pass through the winning channel X and then fall considerably downward, creating a decorative effect. It is possible to increase it further. Almost the same effect can be expected even if the focal length of each lens is uniform.

FIGS. 11A and 11B show a case where the outer circumferential portion 20C as a light diffusing portion is constituted by a Fresnel lens. FIG. 11B shows the appearance of the Fresnel lens. As can be seen from the vertical cross-sectional view of FIG. 11A, it is made up of a collection of step-like minute slopes, and the angle of inclination is such that the farther the slope is from the light source lamp 43, the greater the incident angle of the light rays that enter the slope. i ₁ becomes large, and therefore its refraction angle r ₂ also becomes large. Therefore, the light rays that pass through the outer circumferential portion 20C, which constitutes the Fresnel lens as a whole, are substantially parallel as shown in FIG. 11A. As a result, the transmitted light is not diffused over a wide range, and the winning flow path
It becomes possible to intensively and powerfully illuminate the area.

It is better to provide the unevenness of the lenticular lens and Fresnel lens described in FIGS. 10 and 11 on the incident surface (i.e., the inner surface of the enclosing frame 20) as shown in the figure than on the light diffusion surface. This is advantageous because there is less possibility of contamination due to contact with pachinko balls as they flow down the board surface.

FIG. 3 shows the configuration after removing the surrounding frame 20 from the component board 11, and shows the position aligned with the winning hole 11B shown in FIG. 2, that is, the winning hole 11B.
The arrangement and installation state of the operating lever 30, the detachable micro switch 35, and the illumination means 40, which are installed directly below, are shown. Actuation lever 3
0 is rotatably supported by a rotation shaft 31 fixed to the component board 11, and has a ball mounting portion 30A at one end.
have. Ball mounting portion 30A of actuation lever 30
The ball mounting surface is a gently sloped surface toward an opening 34 on the component substrate that aligns with and communicates with the ball mounting surface when the ball mounting surface rotates downward. Since the pachinko ball that entered the prize opening 11B is placed on this ball placement part 30A,
The weight of the ball causes the operating lever 30 to rotate in the direction of arrow A shown in FIG. 3A. In the illustrated embodiment, the rotation shaft 31 is fixed to the component substrate 11, but the same effect can be achieved by fixing it to the surrounding frame 20 instead. As the operating lever 30 rotates, the bottom surface of the operating lever 30 presses the operating piece 35A of the micro switch 35, closing the internal contact. The micro switch 35 has a fitting hole 35B, which is connected to the positioning pin 37 provided on the component board 11.
The position of the micro switch is determined by mating with the
Thereafter, it is fixed at a predetermined position on the component board 11 with screws 36. A lead wire 38 extending from the microswitch 35 passes through a wiring processing hole 39 provided in the component board 11 and is connected to a control circuit board (not shown) on the back side. A lighting means 40, for example a small lamp 43, is mounted below the micro switch 35. As shown in FIG. 3B in detail, the lamp 43 is inserted into a socket pin 42 attached to an insulating plate 41, so when replacing the lamp, for example, you can pinch the burnt out lamp. All you have to do is pull it out and then insert a new lamp vertically. Actuation lever 30 and micro switch 3
5 is exactly the same, and can be easily carried out from the front side of the game board 3 as long as the glass frame is opened and the surrounding frame 20 is removed. In order to attach the surrounding frame 20, a pair of fitting parts 46 provided on the surrounding frame 20 side are engaged with a pair of positioning pins 45 provided on the component board 11 side in corresponding positions. Therefore, the correct position of the surrounding frame 20 with respect to the component substrate 11 is set. Therefore, after that, it is fixed by screwing the screw 22 into the fastening part 48 provided on the component board 11 side.

FIG. 4 shows the operation of the operating lever 30. When there is no winning ball, as shown by the solid line, the operating lever 30 is pressed against the lower part of the winning opening 11B of the surrounding frame 20 by the return force of the operating piece 35A of the micro switch 35 and is held there. . Next, when a winning ball arrives and is placed on the ball placement section 30A, the actuating lever 30 rotates down to the position shown by the dotted line, and as a result, the actuating piece 35A of the micro switch 35 is pressed and the internal contact closes. As the operating lever 30 is rotated and lowered, the winning balls are guided to the back side of the component board through the opening 34 and processed.

FIG. 5 is an exploded perspective view of the structure of the so-called large-scale variable prize winning device seen from the back side. A swing socket 51 is rotatably attached to the component board 11 to be attached to the game board 3, which closes the horizontally long opening 50a (FIG. 6) until the specific game mode described above occurs. A transmission member 65 (see also FIG. 6) for controlling the opening and closing of the swing socket 51 is rotatably attached to a mounting piece 64 fixed to the back plate 52. This rotation of the transmission member 65 is performed by vertical movement of a plunger 66a driven by a solenoid 66 fixed to the back surface of the game board 3. The opening and closing operation of the swing socket 51 will be explained with reference to FIG. Note that this figure shows a state in which the solenoid 66 is energized and the plunger 66a is fully raised. When the solenoid 66 is energized, the plunger 66a moves upward against the spring force of the return spring 66b.
The transmission member 65 becomes rotatable about the shaft 67 from the position shown by the dotted line to the position shown by the solid line. In this state, the force acting from the transmission member 65 to the swing socket 51 via the engagement portion becomes approximately zero, so the swing socket 51 moves naturally from the position shown by the dotted line to the position shown by the solid line due to its own weight. Rotate. Accordingly, the transmission member 65 rotates from the position shown by the dotted line to the position shown by the solid line under the force from the swing socket 51. The solenoid 66 is energized by the winning slot 11 mentioned earlier.
When the winning ball B enters, the actuating lever 30 is actuated, and the actuating piece 35A of the micro switch 35B is thereby pressed, and the roulette device 15 starts to operate, and the game of the roulette device is started. This is because a specific game mode occurs, and power is supplied from a control circuit board (not shown) in accordance with this. In this way, the swing socket 5
1 opens, the probability of a large number of winning balls occurring in a short period of time increases all at once. A winning ball entering from the swing socket 51 is guided to one location by a pair of winning ball guiding members 56a, 56b. That is, since the upper planes of the members 56a and 56b, which are arranged facing each other with an interval (space) corresponding to one winning ball, are inclined toward the space, the winning balls gather toward that space and fall one by one. I will do it. A known count detector 31 is installed directly below the space. The count detector 31 has an aperture 3 that allows one ball to pass through.
1a, and generates a detection signal every time a ball passes through the opening 31a, and the number of passing winning balls is counted based on this signal.

A back plate 52 arranged behind the horizontally long opening 50a
is provided with a sensing piece 60 that is rotatably supported by a pin 59, so that among the winning balls that enter through the horizontally elongated opening 50a, especially those that enter toward the opening 52a provided in the back plate 52. The winning ball is sensing piece 6
Press 0. The pressed sensing piece 60 is the pin 59
The stopper portion 60c rotates about 45 degrees about the rotation center until the stopper portion 60c comes into contact with the rotation restriction portion 52d.
On the back surface of the back plate 52, a specific condition configuration detector 32 such as a micro switch is fixed on a support base 61, so when the sensing piece 60 is pressed by a winning ball as described above, the micro switch 32 is activated. The actuation piece 32a is actuated and the contact of the microswitch 32 is closed.

When the aforementioned micro switch 35 is activated and a specific game mode occurs in the roulette device 15 (FIG. 13), the swing socket 51 opens and a timer (not shown) starts to operate, resulting in a very high probability of winning. Maintain the state for 30 seconds, for example. In this state, the micro switch 32 described above is activated.
When activated, the continuation conditions are met and the number of times the high winning probability state is maintained will be extended.

A lamp 43 as a lighting means is inserted into two socket pins 42 arranged side by side as shown in FIG. 3B, and an insulating plate 41 is fixed to the component board 11 with screws 28c as shown in FIG. Therefore, the lamp 43 is disposed in the illumination hole 49. Therefore, when replacing the lamp, the lamp can be replaced simply by removing the surrounding frame 20.

There is a window 50b (Figs. 6 and 13) at the bottom of the swinging socket 51, and the window is made of a transparent material so that the inside can be seen through. Therefore, the state of the winning balls rolling on the winning ball guide member can be observed well, and even if balls become jammed, it can be immediately discovered.

FIGS. 7 and 8 show another embodiment of the large-scale variable prize winning device, and the same members as those in the first embodiment described above are indicated by the same symbols with dashes attached. The difference from the first embodiment is that the variable mechanism of the large-scale variable prize winning device and the surrounding frame 20' do not have operating levers or microswitches, but instead are provided with lamps that illuminate in different directions. First, regarding the variable mechanism, a first movable member 70 defining a horizontally elongated opening is rotatably arranged, and when a pachinko ball wins at least one of the winning openings 11B' arranged on both sides of the first movable member 70, a micro Activate the switch (not shown) and game device 15 (first
(Fig. 3) starts operating. If a specific game mode occurs in the game device, a solenoid (not shown) similar to the one described above is activated.
As a result, the first movable member 70 changes from the state shown in FIG. 7A to the state shown in FIG. 7B. At this time, the first
In conjunction with the movement of the movable member 70, the pair of second movable members 72 move along their respective guide holes 74 from the state shown in FIG. 7A to the state shown in FIG. 7B. As is clear from the figure, in FIG. 7B, the second movable member 72
Since most of the pachinko balls that fall upward will flow into the large variable winning opening 11A', the winning probability will be dramatically high.

FIG. 8 shows the state in which the surrounding frame 20' is removed from the component board 11', and the ball that entered from the prize opening 11B' is inserted into the guide wall 80 formed integrally with the surrounding frame 20'.
The light then passes through an opening 34' provided in the component substrate 11' and activates a microswitch (not shown). Lamp 43' mounted on lamp board 41'
is fixed by inserting the lamp board 41' into the support part 86 fixed to the component board 11'.
Compared to the first embodiment, the direction of the lamp is toward the large variable prize opening, which is convenient for illuminating the movement of the second movable member 72 and the falling balls in the vicinity thereof. The front surface and outer circumferential parts 20C' to 20E' of the enclosing frame 20' are made of a diamond cut, a double structure consisting of first and second colored transparent members, a triangular cross section, and a lenticular lens, as in the first embodiment. Because it has a Fresnel lens configuration,
The decorative effect can be enhanced by applying various colors. The surrounding frame 20' is similar to the first embodiment,
By engaging the fitting portion 46' on the surrounding frame 20' side with the positioning pin 45' provided on the component board 11', the proper position of the surrounding frame 20' side with respect to the component board 11' is determined, and then the component board 11' to the fastening part 48' from the outside of the surrounding frame 20'.
By tightening, the surrounding frame 20' is fixed.

[Effect of idea]

As mentioned above, according to the present invention, in the surrounding frame arranged on both sides of the large variable prize opening,
A front plate, stickers, etc. are attached, and the backs of the first and second transparent members have diamond-cut surfaces that expand the surface area and cause diffused reflection, creating a sparkling beauty. A three-dimensional double structure is formed by superimposing a second colored transparent member on the first colored transparent member, and a lenticular lens or a lenticular lens having a triangular cross section is formed on the outer periphery of the first colored transparent member. Like a Fresnel lens, it can diffusely reflect the transmitted light from the illumination lamp, diffuse it over a wide area, or intensively illuminate the falling ball between the two surrounding frames with a parallel beam of light, so the surrounding frame itself, The winning channel section defined between both enclosing frames and the pachinko balls in the winning channel section are extremely colorfully decorated or illuminated, making it possible to further enhance the player's feeling of joy when a specific game mode occurs. Become.
