Description

[Detailed Description of the Invention] [Field of Application] The present invention relates to a technology that is effective when applied to pachinko gaming machines, and in particular, a variable speed control system that is operated by winning a game ball into a specific winning opening provided in a gaming area. The present invention relates to a technique that is effective when used in a pachinko game machine equipped with a display device.

[Prior art] In pachinko gaming machines, the game content is dynamically changed to increase the interest of the game, and the probability of winning is temporarily increased to improve the service to the players.
Various electric winning devices called so-called yakumono have been developed, and for example, they are activated by winning a game ball into a specific winning hole provided in the gaming section, and although the occurrence rate is relatively low, so-called Pachinko gaming machines have been proposed that are equipped with a variable display device or the like that generates a specific pattern called a jackpot.

Conventionally, as the above-mentioned variable display device, codes such as numbers displayed on a plurality of (for example, four) segment-type displays made of LEDs are variably operated depending on the winning of a ball to a specific winning opening in a gaming area. A so-called digital variable display device that is stopped by an automatic stop using a stop switch or a timer, and generates a specific condition (jackpot condition) when the combination of numbers in the stopped state becomes a specific preset combination. Then, several (for example, three) drums with multiple numbers and patterns attached to the outer periphery are rotated and stopped in order by winning a prize in a specific winning slot, and the drum is specified by the combination of numbers and patterns in the stopped state. A so-called rotary drum type variable display device that generates a variable display has been provided.

[Problems] However, conventional rotary drum type variable display devices are roughly divided into two parts: a front frame and a main body, one of which is attached to the front of the game board and the other to the back of the game board. The structure was not connected to each other. Therefore, if any of the moving parts breaks down, the entire main body must be removed, which makes replacing parts troublesome, and also prevents positional deviations during installation, and prevents collisions with falling balls. There were problems such as weak strength.

In addition, the front of the rotating drum held within the main body is covered with a semi-cylindrical transparent protective member, and this protective member is engaged with the mounting hole formed on the game board from the rear of the game board. I was installing the part. Therefore, the amount of protrusion of the transparent protection member toward the gaming area side increases, which obstructs the exchange of batted balls in the left and right gaming areas, that is, the batted balls' movement to the opposite side through the front surface of the variable display device. As a result, it was difficult to sufficiently increase the winning probability of a ball hitting a specific winning slot located below the variable display device or a variable winning device that opens when a specific mode occurs. .

[Objective of the Invention] The object of the invention is to provide a system that is easy to install on a game board, does not cause misalignment, is strong, and is easy to inspect and replace parts in the event of a failure later on. It is an object of the present invention to provide a pachinko game machine equipped with a variable display device that allows the pachinko game to be played.

Another object of the present invention is to allow game balls flowing down in the left and right game areas of the variable display device to pass through the front surface of the variable display device and to frequently interact with each other.

It is an object of the present invention to provide a pachinko game machine equipped with a variable display device that can increase the probability of winning a prize in a specific prize opening or special prize device disposed below the variable display device.

[Means for solving the problem] A front component board that has a relatively small display window in the center and a display section on the top, and also has an opening in the center and a winning ball guiding path, etc. around it. It has a back configuration board, a cylindrical rotation display member and rotation stop means therein,
A variable display device is constituted by a box-shaped variable display mechanism having a rotation drive means on the outside, and the front component board is inserted from the front into a storage chamber formed in the game board, and the back component board is inserted into the storage chamber formed in the game board. The game board is inserted into the storage chamber from the rear and attached so as to sandwich the game board, and is combined with the front component board, and a variable display mechanism section having a rotating display member is fixed to the rear component board. By doing so, the three components that make up the variable display device are organically combined with the game board sandwiched within the storage chamber of the game board, and a transparent protector is attached to the affected area of the display so as to cover the front of the rotary display member. The above objective is achieved by reducing the amount of protrusion of the member into the gaming area.

[Example] FIG. 1 shows an example of the overall configuration of a pachinko game machine equipped with a variable display device according to the present invention, and FIG. 2 shows an example of the configuration of its gaming area. A guide rail 3 is provided to guide the ball fired by the ball launcher 2 driven by the operation dial 2a at the bottom to the upper part of the game board 1. A gaming area is formed in the space surrounded by. In the center of this gaming area, there is a variable display device 4 as a game device, and below it, which normally forms a part of the gaming area, a prize can be won by the occurrence of a specific mode in the variable display bag W4. A variable winning device 5 for converting into a region is provided.

The variable winning device 5 has two types of winning holes, a general winning hole and a special winning hole that constitutes a continuation condition, and an opening/closing door 5a is provided to cover these winning holes. In addition, general winning holes 5b are provided on both sides of the variable winning device 5.

First specific winning lowers are provided on both sides of the variable display device 4, and a second specific winning opening 8 is provided between the variable display device 4 and the variable winning device 5. Among these, the first specific winning lower is a pair of direction setting guide members 13a, 1.3 arranged in an arc shape with an interval of one ball.
b, the lower half has a ball receiving part 7a protruding into the game area, and the direction setting guide members 13a, 13
All the batted balls that pass through space b enter through the semi-cylindrical opening that forms the specific prize opening, pass through the winning ball exit path formed to penetrate the game board, and are collected at the back of the game board where they are detected. . The second specific winning opening 8 is.

It consists of a prize-winning device called a prize-winning chutker that opens upward in the gaming area.

Above the game board 1, there are provided a so-called "top" winning hole 6a consisting of a winning chucker, and top left "'' and top right" winning holes 6b and 6c consisting of a diving type winning device. Furthermore, tulip type hit ball winning devices 9 are arranged diagonally downward and outward from the first specific winning lower.

Further, at the bottom of the game board 1, each of the winning areas 6a to 6c are accidentally placed while falling from above.

An out port 10 is provided for collecting batted balls that do not win prizes such as 7, 8, 9, etc. to the rear of the game board.

Further, at appropriate positions on the surface of the game board 1, there are a large number of obstacle nails 11 that randomly change the direction of the hit balls falling from above, and transfer guide members 12a to 12c that control the falling velocity and direction of the hit balls. They are arranged symmetrically.

Of these, the transfer guiding member 12b is arranged diagonally below the first specific winning lower and slightly more centrally than this, and the direction setting guiding member 13a and the variable display device 4 are connected to each other. A rotating shaft is disposed at a position slightly shifted outward from the centerline c-c' of the distance from the ball-hitting guide surface 41a.

Further, the direction setting guide member 13a is formed such that its terminal end is located below the end of the ball-hitting guide surface 41a of the variable display device. As a result, the batted ball guided by the direction setting guide member 13a and flowing down is easily guided toward the AC surface on the front surface of the variable display device 4, and the ball is easily guided toward the AC surface on the front surface of the variable display device 4. The probability of winning a prize in the winning hole 8 is increased. On both sides of the specific winning hole 8, downstream repulsion members 14 are provided which make it easier for the ball to enter the specific winning hole 8 by collision and rebound of the ball thereon.

A V-shaped flow path (shown with broken lines in FIG. 2) that guides the batted ball toward the winning hole of the variable winning device 5 is formed between the second specific winning hole 8 and the variable winning device 5. Downstream guide member 15
is disposed at the lower end of the downstream guide member 15, in correspondence to the two types of winning holes of the variable winning device 5, it distributes the batted balls to the winning holes, and controls the speed of the winning ball into the variable winning device 5. A dispensing guide member 16 is provided to reduce this.

The width of the distribution guide member 16 is formed to be wider than the width of the winning hole of the variable winning device 5, thereby making the actual width of the winning hole of the variable winning device 5 wider. Further, the downward guide member 15 has a nail device so that the width of the upper end thereof is wider than the width of the distribution guide member 16, and thereby a special game state is established in which the winning opening of the variable winning device 5 is opened. When the ball is shifted, the winning area is expanded beyond the original winning area of the variable winning device 5 to the area where the downstream guide member 15 is arranged, increasing the possibility of winning a hit ball. . The variable winning device 5 is closed when a predetermined number of balls hit a prize or a predetermined time elapses, but due to the distributing action of the distribution guide member 16, the variable winning device 5 is closed at a part (center) of the winning opening of the variable winning device 5 during opening. When the ball hits the special winning hole 5C, the continuation condition is satisfied, and the opening/closing door 5a of the winning hole of the variable winning device 5 is opened again.

A riot prevention member 18 for suppressing riots within the game area is attached.

Furthermore, on the upper part of the holding frame 100 of the pachinko game machine that holds the game board 1 configured as described above, there is a firing device drive lamp 26 that is lit when the operation dial 2a of the batted ball firing device is operated, and a firing device driving lamp 26 that is lit when a specific situation occurs. An indicator lamp 27 that blinks or lights up together with the turbo lamp 22 is provided. This indicator lamp 27 allows an employee of the game parlor to know that a specific situation has occurred even from the end of the island facility.

Furthermore, a supply tray 102 is attached to an opening/closing panel 101 attached to the lower part of the holding frame 100 for holding the batted balls supplied to the batted ball firing device, and a supply tray 102 is attached below the supply tray 102 for storing the prize balls overflowing from the supply tray. A saucer 103 is provided. A variable display stopping means 30 for stopping the variable display device 4 driven by a winning in a specific winning opening is provided on the side (left side in the figure) of the holding frame 100.

In the pachinko game machine configured as described above, when a batted ball hit into the game area by the batted ball firing device wins a specific prize winning lower or 8, the variable display device 4 is driven to fluctuate and the display is displayed on the display window 45a. Each of the three numbers or patterns shown will change. Then, the variable display is stopped by the player pressing the variable display stopping means 30 provided on the holding frame 100 or by auto-stop using a timer, and by the combination of numbers or pictures appearing in the display window 45a at that time. A specific aspect is generated.

When a specific mode occurs, the variable prize winning device 5 is converted to an open state, and the winning probability thereof is changed from zero to a very high state. As a result, a large number of prize balls are generated within a relatively short period of time, and a large number of prize balls are given to players.

3 and 4 show an exploded perspective view and a cross-sectional side view of one embodiment of the variable display device 4. As shown in FIG.

An armor member 41 having the above-mentioned circular arc-shaped ball guiding surface 41a is formed on the upper part of the front substrate 40 of the variable display device 4, and this armor member 41 protrudes forward from the surface of the game board 1. A decorative plate 42 having a lighting member 42a is attached to its front end. The armor member 41 can reduce the speed of the hit ball flowing down from above the game board by using the upper arc-shaped hit ball guide surface 41a, and can smoothly distribute the hit ball to either the left or right game area.

The lower part of the front component board 40 is an exchange surface 43 that is joined to the game board 1 and is substantially flush with the game board 1. Through this exchange surface 43, batted balls flowing down the left and right game areas are allowed to interact, This makes it easier for the ball to fly into the second specific winning hole 8 and the variable winning device 5 located below.

Inside the exchange surface 43, a concave forming wall 44 is provided so as to protrude rearward, that is, into the storage chamber IA provided in the game board 1.

The patterns on the surface of each rotating display member (rotating drum) 72 are visible from the front.

The protective member 46 may be made to have a different thickness like a lens to display an enlarged image.

Further, at the lower part of the recess forming wall 44, four memory display means 49 are arranged in a horizontal line in order to display the number of specific winning lowers and batted balls that have won 8, and on the upper outer wall of the recess forming wall 44. A pair of guide portions 47 are formed in the. In the variable display device 4, the concave portion forming wall 44 is connected to the game board 1.
The front component board 40 is inserted into the storage chamber IA of
It is fixed to the surface of the game board 1 with screws, nails, etc. through mounting holes 40d formed on the periphery of the board.

Corresponding to the front component board 40 which is inserted from the front into the storage chamber IA at the center of the game board and fixed, a substantially rectangular rear component board 50 is attached to the back surface of the game board l. There is. An opening 50a corresponding to the displayed affected area 45a in the front component substrate 40 is formed in the center of the back component substrate 50, and a spacer-shaped opening 50a is formed at the periphery of this opening 50a and at the upper end and both ends of the back component substrate. Upright walls 51 and 52 are formed to have a similar effect. The above-mentioned upstanding walls 51 and 52 formed on the side facing the back surface of the game board 1
On the front side of the back component board 50, there is a guiding path 53 for guiding the batted balls that hit the winning holes 6a to 6c, and a guiding path 53 for guiding the batted balls that hit the winning holes 6a to 6c, and a guide path 53 for guiding the batted balls that hit the left and right specific winning holes. A pair of guiding paths 54 for guiding and a guiding gutter 55 for guiding the winning batted ball to the lower second specific winning hole 8
is provided. In addition, specific winning prize detectors 33 and 34 for detecting guided winning balls are disposed at the downstream ends of the guiding path 54 and the guiding gutter 55, respectively. The detection signals from the specific winning detectors 33 and 34 start the variable operation of the variable display device 4. Also, at the bottom of the back component board 5o is a variable prize bag! ! A driving source 56, such as a solenoid, is installed to operate the opening/closing door 5a provided in the prize opening 5.

Furthermore, a guide receiving part 57 that can be engaged with the guide part 47 at the rear end of the front component board 40 is formed on the standing wall 51 around the opening 50a. The guide receiving portion 57 is inserted into the guide portion 47, and the back component board 50 is attached to the mounting portions 58 provided at the four corners of the back component board 50 using screws or the like.
is fixed to the back of the game board 1. In other words, the front component board 40 is viewed from the front of the game board 1, and the back component board 50 is viewed from the rear.
Attach the game board 1 between them.

As a result, the front component board 40 and the back component board 50 are strengthened so as to mutually reinforce each other in the storage chamber IA.
Moreover, it is installed in a precisely positioned state.

Two pairs of mounting receptacles 59 are formed on the back surface of the back surface component board 50, and a variable display mechanism section 60 is fixed to the mounting receptacles 59 by mounting sections 60a provided on the soil wall and the lower wall. It has become so. The drawing shows the opening 50 of the two pairs of attachment parts 59.
Although only the one above a is shown, the opening 50
A mounting receiving portion is similarly formed below a.

5 to 7 show specific configuration examples of the variable display mechanism section 60.

The variable display mechanism section 60 is housed within a frame 61 formed into a box shape with an open front by an upper wall 61a, a lower wall 61b, side walls 61c, 61d, and a rear wall 61e that are separably connected to each other. It is configured.

Of the walls, the upper wall 61a and the lower wall 61b are each provided with an upright portion 62 having attachment holes 62a along both side edges, and the ends of the side walls 61c and 61d are brought into contact with this upright wall 62. By inserting a screw from the side and screwing it into the mounting hole 62a, the upper wall 61a, the lower wall 61b, and the side walls 61c and 61d are integrated. The rear wall 61e has an upright portion 62 having attachment holes 62b formed on both side edges thereof engaged with the rear end openings of the upper wall 61a, the lower wall 61b, and the side walls 61c, 61d. It is fixed by screwing a screw into the attachment hole 62b from the outside.

A through hole 63 is formed at a position slightly forward from the center of the side walls 61c, 61d, and both ends of a main shaft 64 are inserted into this through hole 63, and the main shaft 64 is inserted between the side walls 61c, 61d. It is designed to be rotatably supported.

The main shaft 64 has a pair of collars 64a at both ends thereof.
are fitted, and the collar 64a is brought into contact with the side walls 61c and 61d, thereby preventing movement in the axial direction.One end of the shaft 64 protrudes from the side wall 61c, and a driven gear 65 is attached thereto. Further, boss portions (4 pieces) 66 protruding outward are formed on the side wall 61c, and this boss portion 66 includes a motor 67a and a first
A storage case 68 that holds the drive means 67 consisting of a transmission section 67b is attached. Drive shaft 67 of drive means 67
A drive gear 69 is attached to the drive gear 69, and the drive gear 69 meshes with the driven gear 65 to change the rotation speed of the drive means 67 and transmit it to the main shaft 64, which is rotated at the most appropriate rotation speed. A transmission section 70 is configured.

The first transmission section 67b allows the main shaft 64 to rotate smoothly by increasing the rotational force of the motor 67a. Additionally, a rotation display member 72 (to be described later) attached to the outer periphery of the main shaft 64 by the second transmission section 70
While the main shaft 64 is being rotated, the main shaft 64 is rotated at such a rotational speed that the player can barely read the numbers and patterns on its surface.

In the groove 6=20-4b formed on the outer periphery of the main shaft 64, three sets of retaining rings 71a made of E-shaped rings, etc.
71b is attached, and each set of stopper 71a, 7
1b, a cylindrical rotation display member 72 is rotatably fitted around the outer periphery of the main shaft 64.

The rotation display member 72 has a shaft portion 7 fitted into the shaft 64.
2a, a disc-shaped main wall 72b formed on the outer periphery thereof, a cylindrical display section 72c formed on the outer periphery of the main wall 72b, and a ratchet section 72d formed on the outer wall of the main wall 72b,
A plurality of light guide portions 72e formed on the inner surface of the main wall 72b
It is composed of.

The above-mentioned stops 71a and 71b each have a rotating display member 7.
The washer 73 is fitted onto the shaft 64 so as to be in contact with one of the two shaft portions 71b, with a gap greater than the width of the two shaft portions 72a. and,
A compression spring 74 is inserted between the washer 73 and the base of the earthen wall 72b of the rotation display member 72, and the repulsive force of the compression spring 74 causes the stopper 71a and the shaft portion 72a to
Frictional force is generated at four contact surfaces: between the spring 74 and the main wall 72b, between the spring 74 and the washer 73, and between the washer 73 and the stop shaft 71b. These friction surfaces transmit the rotational force of the main shaft 64 to the rotation display member 72, and when the rotation of the rotation display member 72 is forcibly stopped from the outside, slipping occurs on each friction surface and the main shaft The rotation of the rotation display member 72 can now be stopped without stopping the rotation of the rotation display member 64.

Moreover, in the above case, each rotation display member 72 is inserted between each pair of stop shafts 71a and 71b, and the adjacent sets of stop shafts 71b and 71a have a gap c1.
Frictional force acts only on one side of each stop shaft 71a, 71b. Therefore, idle rotation of each stopper 71a, 71b is prevented.

In other words, if only one stop shaft is provided between each rotation display member 72, and the compression springs 74 are brought into contact with both sides of the stop shaft, the frictional force will be increased because the frictional force will act on both sides of the stop shaft. There is a risk that the retaining ring, which is simply fitted to the outer periphery of the shaft, may become idly rotated.

In this way, since the three rotation display members 72 are loosely fitted onto one main shaft 64 and configured to follow the rotation due to frictional force, there is no need to provide a rotation drive source for each rotation display member. , each can stop its rotation independently. Along with this, the rotation display member 7
When the main shaft 2 is forcibly stopped, it slips on the four friction surfaces and idles, so that no unreasonable force is applied to the main shaft 64, and the load on the drive means 67 is reduced.

Further, the interval between the stop shafts 71a of each set is set wider than the width of the cylindrical display part 72c of the rotation display member 72, so that there is a gap between each cylindrical display part 72c when attached to the shaft. C2 is formed, and the ratchet portion 72d can be viewed from the gap C2.

The rotation display member 7 corresponds to the ratchet portion 72d.
2, three stopper levers 76 ZS - are arranged behind the side wall 6.
It is rotatably supported by a sub-shaft 77 horizontally suspended between 1c and 61a in parallel with the main shaft 64. Furthermore, three solenoids 78 are attached to the inside of the rear wall 61e to rotate the stopper levers 76 in correspondence with the respective stopper levers 76, and the plungers 7 of each solenoid 78 are attached to the inner side of the rear wall 61e.
The tip of the stopper lever 76 is connected to the rear end of the stopper lever 76 with a pin or the like. On the inner surface of the rear wall 61e, three sets of rib-shaped guide portions 162a and 162b are provided in the vertical direction to accommodate the solenoid 78.
The guide portions 162a and 162b are formed parallel to each other with an interval equal to the width of the guide portions 162a and 162b, and positioning is automatically performed by engaging a solenoid 78 between the guide portions 162a and 162b. In the normal state (demagnetized state) of the solenoid 78, the planter 78a is raised by the force of the return spring 78b, which urges the end locking portion 76a of the stopper lever 76 toward the main shaft, and each rotation is displayed. It comes into contact with the outer periphery of the ratchet portion 72d of the member 72 to prevent its rotation.

However, when the solenoid 78 is energized, the plunger 78a is lowered and the stopper lever 76 is rotated, and the locking portion 76a at the tip is lifted and the ratchet portion 72d is moved.
removed from the outer periphery of the As a result, the rotation preventing force of the ratchet portion 72d is released, and the rotation display member 72 begins to rotate following the rotation of the main shaft 64.

In the above case, since the stopper lever 76 and its driving solenoid 78 are provided for each rotation display member 72, the rotation and stopping of the three rotation display members 72 can be controlled independently. This imparts irregularity to the arrangement of numbers and patterns on the surface of the rotation display member when the rotation is stopped.

Note that the rear wall 6 corresponds to the rear end of the stopper lever 76.
A window 79 is formed in the upper part of 1e, and this window 7
9, the interior of the variable display mechanism section 6'0 can be adjusted. A lid 80 is usually engaged with the window portion 79 and locked with elastic locking pieces 80a at both ends, and a light-blocking seal or the like is pasted on top of the lid 80 to prevent light from leaking inside. Ru.

On the other hand, the main shaft 6 is provided on the inner surface of the side wall 61d.
A plurality of (five in the drawings) light projecting parts 81 are each provided so as to be located on a concentric circle centered on the through hole 63 through which the light emitting part 4 is inserted. The light projecting portion 81 is composed of a through hole and a cylindrical portion that projects inward from the side wall along the periphery of the through hole, and a light emitting unit 82 is held in a corresponding arrangement within each light projecting portion 81 and is held on a light projecting board 82. The element 83 is inserted from the outside of the side wall 61d, and the light projection board 82 is fixed with screws or the like.

Furthermore, a cover 84 that covers the periphery of the light projection board 82 to prevent light from entering inside is attached to the outer surface of the side wall 61d.

On the inner surface of the side wall 61c facing each of the light projecting parts 81,
A cylindrical light receiving section 85 arranged symmetrically with the light projecting section 81 is formed,
A light-receiving board 8 in which a light-receiving element 86 is respectively incorporated.
7 is fixed with screws or the like.

The solenoid 78 is energized by the winning of the ball to the specific winning lower or 8, and when the stopper lever 76 is removed, the three rotation display members 72 are rotated, and the stop switch 3o de-energizes the solenoid 78. When the stopper lever 76 is stopped by being engaged with the ratchet portion 72d, each cylindrical display portion 7
When the numbers or patterns on the surface of 2c are aligned in the specified state,
The arrangement of the patterns on the surface of the cylindrical display section 72c is determined in advance so that the light guide sections 72e inside the earthen wall 72b coincide with each other. Therefore, when the pictures are aligned in a predetermined state and stopped, the light guide portions 72e of each rotating display member 72 are aligned on the detection optical axis of any pair of light emitting element 83 and light receiving element 86.

Then, the light emitted from the light emitting element 83 reaches each light guide section 72.
e, and reaches the light receiving element 86, where it is detected. As a result, it is detected that the numbers or patterns on the surfaces of the three rotating display members 72 are aligned in a predetermined state (occurrence of a specific mode), and the variable winning device 5 is activated for a certain period of time (for example, 30 seconds) or for a predetermined number of seconds (for example, 30 seconds). For example, 10 balls) are opened until there are winning balls, and the continuation condition (winning in special winning hole 5C) is satisfied.
;'/ − Therefore, if you repeat this multiple times (for example, 10 times),
A special gaming state called "Jackpot" can be generated.

In this embodiment, several types of specific modes can be detected using five sets of light emitting and light receiving elements 83 and 86.

Furthermore, three rotation display members 7 are provided on the lower surface of the upper wall 61a.
Rotary position detectors 91 consisting of two reed switches or the like are attached by a mounting board 92 corresponding to the magnets 90 embedded in the two left cylindrical display sections 72c. If the magnets 90 are both located at the upper end when the rotation display member 72 is stopped, the two rotation position detectors 91 are equally turned on. As a result, for example, the variable winning device 5 is smaller than the jackpot state.
It is designed to generate a middle hit condition that gives a profit that causes the game to remain open for a short period of time.

Next, a method for detecting the occurrence of the above specific aspect will be explained in more detail.

In this embodiment, as described above, the light guiding part 72e is provided inside the rotating display member 72 and is parallel to the main shaft 64, and the light projecting part 81 and the light receiving part 85 are arranged to face each other at both ends of the light guiding part 72e, which is parallel to the main shaft. Detection is performed by providing a detection optical axis. Therefore, in principle, light that is orthogonal to the detection optical axis does not interfere with detection. Therefore, if the gap C2 between the three rotary display members 72 attached to the main shaft 64 is sufficiently small, the light entering therefrom will be perpendicular to the detection optical axis and will not cause the detector to malfunction. However, in the above embodiment, the stopper lever 7 is located in the gap C2.
Since the rotation display member 72 is prevented from rotating by entering the tip of the rotation display member 72 and engaging the inner ratchet portion 72d, the gap C2 cannot be made so small.

As a result, the detector may malfunction due to light entering through the gap C2. However, by introducing the stopper lever 76 into the gap C2 and stopping the rotation, the effect of preventing the stopper lever 76 from moving in the lateral direction and preventing the stopper lever from falling off can be obtained.

Therefore, in this embodiment, the stopper lever 7 is
While preventing the stopper lever 76 from falling off by adopting a method of stopping the rotation by entering the stopper lever 76,
Malfunction of the detector due to light entering from the gap C2 was avoided in the following manner.

That is, the first unformed space E1 is formed inside the cylindrical display portion 72e of each rotating display member 72, and the outer diameter of the ratchet portion 72d is made smaller than the inner diameter of the cylindrical display portion 72c by the gap C3. By making the ratchet part 72d face the first unformed space E1, a weight part F1 is created between the first cylindrical display part 72c and the ratchet part 72d. Further, a second unformed cavity E2 is formed inside the ratchet part 72d, and a cylindrical light receiving part 85 is formed in the second unformed cavity E2 of the rotary display member 72 on the light receiving part side (leftmost side). Ratchet part 72d with the tip of
A weight portion F2 is formed between the light guide portions 72e of the first and second rotary display members 72 in the second unformed spaces E2 of the second and third rotary display members 72 from the left. The tip is exposed so that it slightly overlaps the ratchet portion 72d.

As a result, the leftmost rotation display member 72 and the light receiving section 8
5 and the space C2 between each rotary display member 72, it becomes extremely difficult for light to reach the light receiving element 86 in the light receiving section 85, and malfunction of the detector is almost certainly prevented. ing.

Further, by providing the unformed cavities E1 and E2, the weight of the rotary display member 72 can be reduced, and the driving force of the driving means 67 can be reduced.

Next, a rotation stop mechanism for stopping the rotation of the rotation display member 72 will be described in detail with reference to FIGS. 8 and 9.

As shown in an enlarged view in FIG. 9, the outer periphery of the ratchet portion 72d includes an engaging surface 172a that is inclined slightly outward from the normal line G in the radial direction, and a reinforcement that is approximately perpendicular to the engaging surface 172a. A chevron-shaped pawl 172 is formed continuously along the circumferential direction, and includes a surface 172b and a communication surface 172C that reaches the base of the engagement surface 172a at a gentle inclination angle from the reinforcing surface 172b. The number of pawls 172 on the outer periphery of the ratchet portion 72d is the same as the number of numbers or pictures attached to the surface of the cylindrical display portion 72c.

The sub-shaft 77 that holds the stopper lever 76 has a tangent line H that is perpendicular to the normal line G that passes through the center of the ratchet portion 72d.
It is placed a distance outside the extension line of the line. As a result, when the stopper lever 76 is rotated by the solenoid 78 in a direction away from the ratchet part 72d, the tip locking part 76a is rotated not in the direction of the normal line G but in a direction away from this. Therefore, when the stopper lever 76 is disengaged from the ratchet portion 72d, it is rotated outward while moving toward the front of the pawl 172, that is, in the moving direction. the result.

The frictional force between the distal end locking portion 76a of the stopper lever 76 and the ratchet portion 72d during disengagement is reduced.

The stopper lever can be removed with relatively light force.

Furthermore, the end locking portion 76a of the stopper lever 76 has a shape that perfectly engages with the angle formed by the engaging surface 172a forming the pawl 172 and the communication surface 172C when engaged with the ratchet portion 72d. It is formed. This reliably stops the rotation of the ratchet portion 72d, prevents so-called double-stopping, in which the locking portion 76a comes off from the pawl 172 after once stopping and then stops again when it engages with the next pawl. , the engagement surface 172a and the communication surface 1 at the time of disengagement.
Wear of 72c is suppressed, and displacement due to vibration during engagement is prevented.

Further, since the reinforcing surface 172b is formed at the tip of the claw 172, the chevron of the claw is less likely to be scraped off compared to a case where the tip has an acute angle. Therefore, even if frequent engagement and disengagement operations are repeated for a long period of time, there is little wear and reliable stopping is guaranteed.

Note that on the lower surface of the lower wall 61b that constitutes the frame 61 of the variable display mechanism section 60 configured as described above.

A relay board 93 that constitutes a repeater is attached.

This relay board 93 includes the rotation driving means 67 and the rotation stop solenoid 78 provided in the variable display mechanism section 60.
, a plug 94a at the end of each lead wire pulled out from the light projecting board 82, the receiving board 87, and the rotational position detector 91 that constitute a specific mode occurrence detector (big hit, medium hit detector),
94b.

Terminal block 95a for inserting 94c and 94d.

95b, 95c, and 95d are provided. Then, once the lead wires are gathered on the relay board 93, they are connected to the second relay board 97 provided on the back component board 50 by a bundle of connection wires 96 connected to each terminal block 95a to 95d. Control board 9 equipped with a control circuit consisting of a CPU, etc.
8 (see Figure 10).

This makes it easier to assemble the lead wires drawn out from the variable display mechanism section 60, which has a large number of electrical drive sources and detectors, and to facilitate the handling of the variable display mechanism section.
The lead wire of the variable display mechanism part is prevented from getting entangled with parts such as the winning ball payout device provided on the back side of the game board. Also, since each lead wire is bundled into a bundle of connection wires 96 and then connected to the control board 98 via the second relay board 97, the variable display mechanism section can be assembled to the control board 98 later. Electrical connection work can also be done very easily.

Furthermore, each terminal (pin) on the terminal blocks 95a to 95d
are arranged parallel to the lower wall 61b, and the plugs 94a to 94d at the ends of the lead wires are respectively inserted from the horizontal direction. Therefore, compared to the case where the plug is inserted at right angles to the lower wall 61b, the amount of protrusion from the wall surface is smaller, and the entire variable display mechanism becomes more compact.

Moreover, the relay board 93 is connected to the lower wall 61 of the variable display mechanism section 60.
Since the relay board 93 is attached to
The Joule heat generated in this process is sufficiently radiated, and local temperature increases can be prevented. That is, there is not enough space from the top to the side of the variable display mechanism section 60 because the winning ball storage tank, winning ball payout device, etc. are arranged in close proximity thereto. On the other hand, since the variable winning device is only protruded a little further downward, a relatively wide space is secured.

FIG. 10 is a drawing of the variable display device 4 seen from behind the game board. The second relay board 97 is disposed at the upper left corner of the back side component board 50 attached to the back side of the game board 1,
Here, a connection line 96 is extended and connected from the first relay board 93 mounted on the lower surface of the lower wall 61b of the variable display mechanism section 60. Second relay board 97
In addition, lead wires from the lighting means 25 on both sides, the solenoid 56 disposed at the bottom of the back component board 50, specific winning detection@33, 34, etc. are also connected to the second It is electrically connected via a relay board 97 to a control board 98 provided on the back of each pachinko game machine.

Below the back structure board 50, the back mechanism part of the variable winning device 5 is arranged so as to penetrate the game board and protrude rearward, and there is an opening/closing door that covers the winning opening on the front side of the variable winning device 5. The plunger tip of the solenoid 56 is arranged above the rear end of the transmission member 5d connected to the transmission member 5c (see FIG. 2) so as to face it.

The ROM 220 stores programs executed by the CPU 210 and fixed data.

The RAM 230 provides a work area for the CPU 210 and a storage area for variable data.

The address decoder 240 decodes address data (Ao = A 11 ) output from the CPU 210 to generate a large number of alternative selection signals 81 to S9. The decoding operation is performed by activating either the read control signal (RD) or the write control signal (WD). These two control signals (RD/WD) are issued from the CPU 210. Both signals (RD/WD) are ORed together by logic gate G1. This logical sum becomes a control signal for the address decoder 240.

Selection signals 81~ output from address decoder 240
A part of S9 (S8.S9) is used as a chip select signal for the ROM 220 and RAM 230.

Further, other selection signals 81 to S7 are used to control input/output circuits within the I10 unit 250, which will be described later.

In other words, the input and output channels are placed in the address space.

The so-called memory Matsubuto I10 system is adopted. By adopting this memory Matsubuto I10 method, input/output can be performed from any input/output circuit using the simple process of accessing a specific address, without the need for complex procedures such as opening and closing input/output channels. It is designed to perform an action.

The I10 unit 250 forms an interface between the control device and the pachinko gaming machine main body 300. This I1
The 0 unit 250 is provided with a large number of input/output circuits, as will be described later. The operation of each input/output circuit is individually controlled by the selection signals 81 to S7. Although the individual configurations of the input/output circuit will be described later, for example, a decoder, a latch circuit, a driver, a buffer gate, an amplifier, etc. are used.

The clock generating means 280 uses a crystal oscillator X as a frequency reference.
By using t a 1 (4 MHz), for example, a 2 MHz high precision clock pulse φk is generated. This clock pulse φ is applied to the clock terminal GK of the CPU 210.

The reset signal generating means 290 generates the clock pulse φ
A reset pulse φt of a constant period is generated from k. This reset pulse φt is applied to the reset terminal R of the CPU 210. In the case where the reset signal generating means 290 is simply and small-scale configured by a counter or the like, the reset pulse φt has a duty width, that is, a pulse width that is long enough to reliably reset the CPU 210. has been done. Further, the pulse generation interval, that is, the period, is set to be reliably longer than the processing time for the CPU 210 to execute the program instructions stored in the ROM.

Furthermore, since the reset interval of the CPU 210 is a constant cycle, by storing the number of resets in the RAM 230, the so-called 677)-1-+'v

[Operations/Effects] As explained above, the present invention has a front component substrate that has a relatively small display window section in the center and a display section on the upper part, and also has an opening section in the center and a display section around it. A variable display device is constructed by a back component substrate having a winning ball guiding path, etc., a box-shaped variable display mechanism having a cylindrical rotating display member and its rotation stopping means inside, and its rotation driving means outside. , the front component board is inserted into the storage chamber formed in the game board from the front, and the back component board is inserted into the storage chamber from the rear of the game board so that the game board is sandwiched between the boards. Since the variable display mechanism section having the rotary display member is coupled to the front component board and fixed to the rear component board, the three components making up the variable display device can be moved inside the storage chamber of the game board. Due to the effect of being organically connected with the game board in between, it is easy to install on the game board, does not cause misalignment, and has strong strength.
