The present invention relates to a large variable winning device in which maintenance and inspection of a pair of winning devices provided on the left and right sides of a large variable winning opening can be performed more efficiently from the front side of the game board.

[Conventional technology]

First, with reference to FIG. 7, the outline of a pachinko game machine equipped with such a large-scale variable prize winning device on the game board will be explained. In the figure, 1 is the main body of the pachinko machine, 2 is its front frame, 3 is a game board that is fixed from the back side into a large window hole in the center of the front frame, and 4
5 is a metal frame attached to the periphery of the window hole in the front frame.
is a guide rail made of a band-shaped metal plate for regulating the passage area of pachinko balls on the game board, and the game section 6 surrounded by the guide rail in a circular shape has a mechanism for changing the winning probability by opening and closing operations. Variable prize winning devices 7a, 7b, a plurality of winning prize devices 8, etc., which can perform various prize winnings, are provided. Reference numeral 9 denotes 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 various winning devices by lighting lamps. Reference numeral 10 denotes a termination indicator, which indicates the end of the game by lighting a lamp when a predetermined number of prize balls have been ejected.

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.

Reference numeral 19 denotes a large variable prize winning device provided at the lower part of the gaming section 6, and its component board 11 includes a horizontally long opening 11A (so-called large variable winning hole) that can receive a plurality of winning balls at the same time when opened. and a pair of winning devices 11C that are located on both sides of the ball and can receive one winning ball.

To explain an example of the gaming mode of a pachinko machine equipped with such a large variable winning device, a pair of winning devices 1
When a pachinko ball wins in at least one of the winning devices, a micro switch is activated, which is installed near the back of the winning device, and the most common method is to face the opening from the rear of the component board.
In response to this, the roulette device 15 starts operating, and the electromagnetic solenoid provided on the back side of the game board 3 is energized according to the game result of the roulette device, and the horizontally elongated opening 11A is opened by the energization. Ru. In this way, when a pachinko ball wins in at least one of the pair of winning devices 11C,
The roulette machine 15 starts operating, and a roulette game is started that has the possibility of generating a specific game mode that is very attractive to the player. The specific game mode that is attractive to the player is determined by the game result of the roulette device 15 (generally, when all numbers are 7), the electromagnetic mode provided on the back of the game board 3 The solenoid is energized, and the large variable prize opening 11A changes from a state with a winning probability of 0 to a state with a very high winning probability for a relatively long time (for example, 30
As a result, a large number of winning balls are generated in a short period of time, and many prize balls are given to players. When such a specific game mode occurs, a lamp built into the winning device 11C flashes intermittently or lights up continuously in short cycles to notify the player of the occurrence of the specific game mode. Note that the starting condition for the roulette game is not limited to the winning of pachinko balls to the winning devices 11C on both sides of the large variable winning device 19, but also the winning of pachinko balls to other winning devices, such as the winning device 8, etc. Good too.

[Problem that the invention attempts to solve]

In the conventional pachinko machine described above, the most common method for installing a micro switch for detecting the winning of a pachinko ball in the winning devices on both sides is to open the switch lever from the rear of the component board 11. Since the micro switch is located as inconspicuously as possible, if the operation of the micro switch needs to be inspected or parts replaced, simply opening the front glass frame of the Pachinko machine 1 will not allow you to do so. It was not possible to inspect and replace the pachinko machine, and it was necessary to open the front frame 2 of the pachinko machine from the wooden frame (not shown) and perform such work from the back side of the game board. For this reason,
Inconveniently, inspection and replacement work takes a long time, causing discomfort and inconvenience to players. Not only that, a failure of the winning detector is a fatal failure in playing the game, so the use of the pachinko machine has to be stopped, causing a deterioration in the operating rate of the pachinko game machine. Although a malfunctioning lamp in a prize-winning device may not directly impede the game itself, playing pachinko with a malfunctioning lamp would greatly impair the enjoyment of the game.

The present invention aims to solve the problems of the prior art, and the replacement and maintenance inspection of the electric switch means and its operating members or lighting means is performed by removing the enclosing frame provided on the side of the game board. To improve the operation rate of a pachinko game machine by simply and quickly performing the operation from the front side of a component board by only using the machine, and also to improve the heat dissipation effect within the surrounding frame.

[Means for solving problems]

An enclosing frame defining a winning opening is arranged on both sides of a first opening capable of receiving a plurality of winning balls at the same time, and an operating lever, an electric switch means, and an illumination means are arranged inside the enclosing frame. Therefore, the operating lever, electric switch means, and lighting means can be replaced and maintained from the game board side by simply removing the glass frame and the surrounding frame, which can be easily opened and closed, without requiring opening and closing from the wooden frame of the front frame. It is characterized by being able to be performed freely and easily.

〔Example〕

FIG. 1 is a slanted view showing one embodiment of the present invention, in which a large variable prize opening 1 provided on a component board 11 is shown.
1A (in an open state) and the appearance of winning devices 11B provided on both sides thereof are shown. Winning device 1 provided on both sides of large winning opening 11A
The surrounding frame 20 of 1B can be easily 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 2B.
is shown. That is, the surrounding frame 20 is preferably molded using a colored transparent plastic material, and the upper part thereof is cut out to form a prize opening 20A capable of receiving one winning ball. Surrounding frame 20
The front side becomes the first colored transparent member 20B, and the lower half of the back side is decorated with a diamond cut D, so that it reflects and transmits a wide variety of light from inside and outside to enhance the glittering and decorative effect. can. The front surface of the surrounding frame 20 (first colored transparent member 2
On the upper half of the prize opening 20A side (on the front side of 0B), a front decorative plate 21 having a concave portion 21b for attaching a sticker with a design to enhance decorativeness or adding color is glued. . The second colored transparent member 20C, which has a diamond cut on its back surface, is fitted and bonded from the front or back into an opening having a similar shape provided in a part of the first colored transparent member 20B. The cutting direction of the diamond cut is determined by the first colored transparent member 20B and the second colored transparent member 20C.
In addition to this, by using transparent materials of different colors, the decorative effect is further enhanced by further diffusing light and harmonizing the colors with the colored transparent materials of multiple colors. be able to. Outer periphery 20 of enclosing frame 20
D, 20E, and 20F are provided with a light diffusing portion on their inner surfaces that has a fine semicircular cross-sectional shape or sawtooth-like unevenness, so that the light from the lamp provided inside the surrounding frame 20 is As a result of being refracted in various ways in the light diffusing section, the outer peripheral portions 20D, 20
Light is emitted from E and 20F toward the outside in various directions, and as with the first and second colored transparent members 20B and 20C provided on the front surface of the surrounding frame 20, the decorative effect of the light can be enhanced. These outer peripheral parts 20D, 20E, 20F are colored transparent members 20
Similar to B and 20C, it can be constructed from a transparent material or various colored transparent members, thereby enhancing the decorative effect with a variety of colors. In addition, the outer peripheral part 20D, that is, the upper end part 20G on the side of the large variable winning hole 11A, is designed to guide the pachinko balls that flow down the game board surface and hit here toward the large variable winning hole 11A side.
It is cut to form a sloped surface.

FIG. 3 shows the configuration after the enclosure frame 20 is removed from the component board 11 by removing the screws 22, and is installed at a position aligned with the winning opening 20A shown in FIG. 2, that is, directly below the winning opening 20A. operating lever 30, detachable micro switch 35
Also, the arrangement of the illumination means 40 and its mounting state are clearly shown. The actuation lever 30 is rotatably supported by a rotation shaft 31 fixed to the component board 11, and has a ball mounting portion 30A at its free end. The ball mounting surface of the ball mounting portion 30A of the actuating lever 30 forms a gentle slope toward the opening (second opening) 34 of the component substrate that aligns with the ball mounting portion 30A when the operating lever 30 is rotated and lowered. Since the ball entering from the prize opening 20A rides on the ball mounting portion 30A, the weight of the ball causes the operating lever 30 to rotate in the direction shown by arrow A 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 fitted with a positioning pin 37 provided on the component board 11 to determine a predetermined mounting position of the micro switch. is fixed in place. A lead wire 38 extending from the micro switch 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 of the game board. This wiring processing hole 39, the opening 34 above it, and the illumination hole 4 described below.
As will be explained later, the reference numeral 9 also functions as a ventilation hole for dissipating heat generated in the surrounding frame 20 by the illumination means 40 described below to the outside. 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. The same goes for replacing the actuating lever 30 and micro switch 35. First, open the glass frame of the pachinko machine, which can be easily opened, and then remove the enclosing frame 20. This can be easily carried out from the front side of the game board 3 without opening it from the frame. To attach the surrounding frame 20, use a pair of positioning pins 4 provided on the component board 11 side.
5, the correct position of the surrounding frame 20 with respect to the component substrate 11 is set by engaging a pair of fitting portions 46 provided on the surrounding frame 20 side at positions corresponding thereto. Therefore, after that, screw 2
2 is fixed by screwing into a fastening portion 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 moved by the return force of the operating piece 35A of the micro switch 35 to the stopper part 2 provided at the lower part of the winning opening 20A of the surrounding frame 20.
It is raised to 0H and held there. Next, when the winning ball arrives and is placed on the ball placement section 30A, the operating lever 30 rotates and descends to the position shown by the dotted line.
As a result, the operating piece 35A of the micro switch 35 is pressed and the internal contacts are closed. The pachinko ball is guided to the back side of the component board 11 through the opening 34 as the operating lever 30 rotates and descends.

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. The component board 11 to be attached to the game board 3 has a horizontally long opening 50a (see FIG. 6) until the specific game mode described above occurs.
A swing socket 51 that closes the swing socket 51 is rotatably mounted, and a transmission member 65 (see also FIG. 6) that controls the opening and closing of the swing socket 51 is fixed to the back plate 52. 64 so as to be rotatable. 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, so that the transmission member 65 is in a state where it can rotate about the shaft 67 from the position shown by the dotted line to the position shown by the solid line. become. 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. As mentioned above as an example, the solenoid 66 is energized when the winning ball enters the winning hole 20A, and the actuating lever 30 is actuated, thereby pressing the actuating piece 35A of the micro switch 35B. is,
This is because the roulette machine 15 starts operating in response to the contact being closed, and power is supplied from the power supply in accordance with the game result. When the swing socket 51 opens in this way, the probability that a large number of winning balls will occur in a short period of time increases at once. Winning balls entering from the swinging socket 51 are passed through a pair of winning ball guiding members 56
a, 56b to one location. That is, since the upper planes of the members 56a and 56b, which are arranged facing each other with an interval (space) of 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 31a that allows one ball to pass through, and generates a signal every time a ball passes through the aperture 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.

The micro switch 35 explained earlier is activated,
Further, when a specific game mode occurs in the roulette machine 15 (FIG. 7), the swing socket 51 opens and a timer (not shown) starts operating, maintaining a state with a very high winning probability for, for example, 30 seconds. If the microswitch 32 described above operates even once in this state, the continuation condition is satisfied, and the number of times the high probability state is maintained is extended. When such a state is repeated several times, it is an attractive state in which the player can obtain a large number of prize balls.

Lamps 43 as illumination means are inserted into two socket pins 42 arranged side by side as shown in FIG. Since the lamp 43 is fixed in place, the lamp 43 is disposed within the illumination hole 49. Therefore, when replacing the lamp, the enclosing frame 2
It is easy to replace by simply removing 0.

There is a window part 50b (Figs. 6 and 7) at the bottom of the swinging socket 51, and the window part is made of a transparent material so that the inside can be seen through. Winning ball guide members 56a, 56b
It is possible to closely observe the state of winning balls rolling on the top, and even if a ball gets jammed, it can be immediately discovered.

[Effect of idea]

As is clear from the configuration described above, according to the present invention, parts such as actuating levers, detection means such as micro switches, and lighting means such as small lamps can be easily removed by simply removing the surrounding frame (without having to open the front frame from the wooden frame). Since the machine can be easily and quickly maintained, inspected, or replaced with parts, it does not make players feel uncomfortable, and it has a great effect on improving the operating rate of the pachinko game machine. Further, since various parts can be arranged inside the enclosing frame, the entire device can be made compact and the back side of the component board can be simplified, making it possible to speed up the assembly work and reduce the installation space. In addition, since it has an illumination means that emits light according to the game mode, there is an effect that the game content is visually displayed by the illumination. Furthermore, multiple openings (winning opening, wiring processing hole, lighting hole) opened in the component board.
also functions as a radiation hole for heat generated from the lighting means. Each time the operating lever rotates, the high-temperature air within the surrounding frame is forcibly discharged to the outside of the heat radiation hole, so that the operating lever has the effect of functioning as a ventilator.
