Description

[Detailed description of the invention] [Field of application] This invention is used for a variable display device that is installed in the gaming area of a pachinko game machine and is activated when a game ball enters a specific winning hole. Concerning effective techniques.

[Prior art] Pachinko machines dynamically change the content of the game to increase the interest of the game, as well as temporarily increase the winning probability and improve the service to players. A variety of electric winning devices called () have been developed, and for example, they are activated when a game ball enters a specific winning hole provided in the gaming section, and although the occurrence rate is relatively low, it is possible to win a so-called jackpot. 2. Description of the Related Art Pachinko gaming machines equipped with variable display devices and the like that generate specific modes have been proposed.

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 can be varied depending on the winning of a ball to a specific winning opening in a gaming area. A so-called digital variable display that is stopped by an automatic stop using a stop switch or a timer, and a specific mode (jackpot condition) is generated when the combination of numbers in the stopped state reaches a preset specific combination. The device and several (for example, three) drums with multiple numbers, patterns, etc. attached to the outer periphery are rotated by winning a prize in a specific winning slot, and are stopped in order by a stop switch or timer, and in the stopped state. 2. Description of the Related Art A so-called rotating drum type variable display device is provided that generates a specific mode by a combination of numbers and pictures.

[Problems] It has become clear that in the above rotary drum type variable display device, problems arise when a commercially available motor is used to directly rotate the shaft having the rotary drum. In other words, if the circumferential speed of the rotating drum is slow, players can easily read the numbers or patterns around the rotating drum while the drum is rotating. You can see how the display changes until the rotating drum stops. Therefore, by pressing the stop switch at an appropriate timing, it is possible to consciously generate a specific mode.
Expert players are able to obtain far more product balls than beginners, making it impossible to ensure fairness in the game. Moreover, pachinko game parlors may also suffer unexpected disadvantages due to the occurrence of a number of specific conditions.

On the other hand, if the circumferential speed of the rotating drum of the rotating drum type variable display device is too fast, no matter how much the player stares at the surface of the drum, he or she will not be able to read the numbers or patterns on the surface at all while the drum is rotating. Therefore, players may lose their desire to desperately watch the drum while it is rotating, which may further reduce their desire to play pachinko.

[Purpose of the invention] The purpose of this invention is to improve the fairness of gaming in pachinko machines that have a rotary drum-type variable display device, to prevent pachinko parlors from suffering unexpected disadvantages, and to improve the quality of play for players. The purpose of the present invention is to prevent a decline in the player's desire to play.

The above and other objects and novel features of this invention will become clear from the description of this specification and the accompanying drawings.

[Means for solving the problem] This invention is to attach a plurality of rotating display members (rotating drums) around one shaft so that they can follow and rotate freely, and to rotate this shaft with a motor. Between the shaft and the shaft, there is a first transmission section that reduces the rotational speed of the motor and increases the driving force, and a second transmission section that converts the circumferential speed of the rotation display member attached to the shaft to an appropriate speed. By providing a stop switch and rotating the rotating display member at such a speed that the player can barely discern the numbers and patterns on the surface of the rotating display member by staring at the surface of the rotating display member. Although it is not possible to consciously generate a specific mode at the timing of the operation, being able to identify the numbers and patterns on the surface while rotating increases concentration on the variable display device, and also reduces the psychological state in which the specific mode is likely to occur. This aims to achieve the above-mentioned objectives of ensuring fairness in gaming, preventing pachinko gaming parlors from suffering unexpected disadvantages, and preventing players from losing their desire to play.

[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.

In the pachinko game machine configured as described above, when a ball hit into the game area by the ball launcher enters the specific winning hole 7 or 8, the variable display device 4 is driven to fluctuate, and the display window 45a is The three numbers or patterns displayed are changed. Then, the variable display is stopped when the player presses the variable display stop means 30 provided on the holding frame 100 or by auto-stop using a timer, and at this time, the display window section 45a
A specific mode is generated by a combination of numbers or patterns that appear.

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.

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

An armor member 41 having the above-mentioned arc-shaped ball guide surface 41a is formed on the upper part of the front component board 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 the upper arcuate 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 forms an exchange surface 43 which is joined to the game board 1 and forms approximately the same plane as 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.

In this way, by integrally forming the front component board 40 with the armor member 41, the AC surface 43, the recess forming wall 44, and the display panel 45, it is different from the conventional type in which the inside of the AC surface 43 is empty. It has higher rigidity than the component board of the variable prize winning device. The center of the display panel 45, ie, the periphery of the display window 45a, is curved so as to protrude forward, and an illumination section 45b containing a lamp is provided at the top. Further, a segment type display 45c is arranged in the center of the illumination part 45b to display the number of openings of the variable prize winning device 5 when the specific mode occurs.

A transparent protective member 46 is attached to the back of the display window 45a formed at the center of the display panel 45.
is attached so that the patterns on the surfaces of three rotating display members (rotary drums) 72 in a variable display mechanism section 60 (described later) disposed behind the front component board 40 can be seen from the front. Protective member 46
may be enlarged and displayed by changing the thickness like a lens.

Furthermore, four memory display means 49 are arranged in a row horizontally at the lower part of the recess forming wall 44 in order to display the memorized number of batted balls that won the specific winning holes 7 and 8, and the upper part of the recess forming wall 44 A pair of guide portions 47 are formed on the outer wall. In the variable display device 4, the recess forming wall 44 is the storage chamber 1A of the game board 1.
In the inserted state, it is fixed to the surface of the game board 1 with screws, nails, etc. through a mounting hole 40d formed at the periphery of the front component board 40.

In correspondence with the front component board 40, which is inserted from the front into the storage chamber 1A at the center of the game board and fixed therein, a substantially rectangular rear component board 50 is attached to the back surface of the game board 1. There is. The front component board 40 is located in the center of the back component board 50.
An opening 50a corresponding to the central display window 45a is formed, and upright walls 51 and 52 acting like spacers are formed at the periphery of this opening 50a and at the top and both sides of the back component substrate, respectively. There is. The top prize openings 6a to 6c are provided on the front surface of the back surface component board 50 so as to be located in a space surrounded by the upstanding walls 51 and 52 formed on the side facing the back surface of the game board 1. A guiding path 53 for guiding the winning batted ball, a pair of guiding paths 54 for guiding the winning batted ball in the left and right specific winning openings 7, and a guiding gutter 5 for guiding the winning batted ball in the lower second specific winning opening 8.
5 is provided. In addition, these taxiways 54
At the downstream end of the guide gutter 55, specific winning prize detectors 33 and 34 for detecting the guided winning balls are arranged, respectively. This specific prize detector 3
The varying operation of the variable display device 4 is started by the detection signals 3 and 34. Further, a drive source 56 such as a solenoid that operates the opening/closing door 5a provided at the winning opening of the variable winning device 5 is attached to the lower part of the back surface component board 50.

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. This guide receiving part 57 is inserted into the guide part 47, and attachment parts 58 are provided at the four corners of the back component board 50.
At this step, the back component board 50 is fixed to the back surface of the game board 1 with screws or the like. 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 firmly and accurately positioned so as to reinforce each other within the storage chamber 1A.

Two pairs of attachment receiving parts 5 are provided on the back side of the back side component board 50.
9 is formed, and a variable display mechanism section 60 is fixed to this attachment receiving part 59 by attachment parts 60a provided on the upper and lower walls. Although only the two pairs of attachment receptacles 59 above the opening 50a are shown in the drawing, an attachment receptacle is similarly formed below the opening 50a.

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

The variable display mechanism section 60 includes an upper wall 61a, a lower wall 61b, and side walls 61c, 6 which are separably connected to each other.
1d and a rear wall 61e, it is configured within a frame 61 that is formed into a box shape with an open front.

Of the walls, the upper wall 61a and the lower wall 61b are each provided with an upright portion 62 having a mounting hole 62a along both side edges, and the ends of the side walls 61c, 61d are brought into contact with this upright wall 62. By inserting screws from the side and screwing them into the mounting holes 62a, the upper wall 61a, the lower wall 61b and the side wall 61c,
61d is integrated. The rear wall 61e has an upright portion 62 having attachment holes 62b formed on both side edges thereof.
The upper wall 61a, the lower wall 61b and the side walls 61c, 6
1d to engage with the rear end opening of the side walls 61c, 6.
It is designed to be fixed by screwing a screw into the attachment hole 62b from the outside of 1d.

A through hole 63 is formed at a position slightly forward from the center of the side walls 61c, 61d, and both ends of the main shaft 64 are inserted into this through hole 63.
It is designed to be rotatably supported between 1d. A pair of collars 64a are fitted to both ends of the main shaft 64, and the collars 64a abut against the side walls 61c, 61d to prevent movement in the axial direction. The driven gear 65 protrudes further and is attached thereto. Further, boss portions (4 pieces) 66 that protrude outward are formed on the side wall 61c, and this boss portion 66 holds a driving means 67 consisting of a motor 67a and a first transmission portion 67b that decelerates the rotation of the motor 67a. A storage case 68 is attached. Drive means 6
A drive gear 69 is attached to the drive shaft 67c of No. 7,
The driving gear 69 is meshed with the driven gear 65 to change the rotational speed of the driving means 67 and transmit it to the main shaft 64, thereby forming a second transmission section 70 that rotates the main shaft 64 at the most appropriate rotational speed. .

The first transmission section 67b causes the motor 67a to
By increasing the rotational force of the main shaft 64, the main shaft 64 can be smoothly rotated. In addition, the second transmission section 7
0, the main shaft is rotated at such a rotational speed that the player can barely read the numbers and patterns on its surface while the rotation display member 72, which will be described later and is attached to the outer periphery of the main shaft 64, is being rotated. 64 will now be rotated.

Groove 6 formed on the outer periphery of the main shaft 64
4b, three sets of retaining rings 7 made of E-type rings etc.
1a and 71b, and a cylindrical rotation display member 72 is rotatably fitted on the outer periphery of the main shaft 64 between each set of retaining rings 71a and 71b.

The rotation display member 72 includes a shaft portion 72a fitted to the shaft 64, a disk-shaped main wall 72b formed on the outer periphery of the shaft portion 72a, a cylindrical display portion 72c formed on the outer periphery of the main wall 72b, and a main wall. The main wall 72b includes a ratchet portion 72d formed on the outer wall thereof, and a plurality of light guide portions 72e formed on the inner surface of the main wall 72b.

The retaining rings 71a and 71b are arranged so as to have an interval larger than the width of the shaft portion 72a of the rotation display member 72, and one of the retaining rings 71a and 71b is
The washer 73 is attached to the shaft 64 so as to be in contact with 1b.
is mated to. A compression spring 74 is inserted between the washer 73 and the base of the main wall 72b of the rotation display member 72.
Due to the repulsive force of 4, the retaining ring 71a and the shaft portion 72a
between the spring 74 and the main wall 72b, between the spring 74
Frictional force is generated at four contact surfaces between the washer 73 and the washer 73 and between the washer 73 and the retaining ring 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. The rotation of the rotation display member 72 can now be stopped without stopping the rotation of the main shaft 64.

Moreover, in the above case, each rotation display member 72 is inserted between each pair of retaining rings 71a and 71b, and adjacent sets of retaining rings 71b and 71a are spaced apart.
C ₁ , each retaining ring 71a, 71b
Frictional force acts only on one side. Therefore, each retaining ring 71a, 71b is prevented from idling. In other words, if only one retaining ring is disposed between each rotation display member 72, and the compression springs 74 are brought into contact with both sides of the retaining ring, the frictional force will increase because the frictional force will act on both sides of the retaining ring. There is a risk that the retaining ring, which is simply fitted around the outer periphery of the shaft, will simply spin idly.

In this way, since the three rotation display members 72 are loosely fitted onto one main shaft 64 and are configured to follow and rotate due to frictional force, a rotation drive source is provided for each rotation display member. It becomes possible to stop the rotation of each of them independently. At the same time, when the rotation display member 72 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 retaining rings 71a of each set is set wider than the width of the cylindrical display part 72c of the rotation display member 72, so that when the retaining ring 71a is attached to the shaft, the distance between each cylindrical display part 72c is A gap _C2 is formed in the gap C2, and the ratchet portion 72d can be viewed from the gap _C2 .

Three stopper levers 76 are provided at the rear of the rotation display member 72 corresponding to the ratchet portion 72d.
These stopper levers 76 are rotatably supported by a subshaft 77 that is horizontally suspended parallel to the main shaft 64 between the side walls 61c and 61d. Furthermore, three solenoids 78 are attached to the inside of the rear wall 61e to rotate the respective stopper levers 76, and the tip of the plunger 78a of each solenoid 78 is attached to a pin or the like at the rear end of the stopper lever 76. are connected. On the inner surface of the rear wall 61e, three sets of rib-shaped guide parts 162a and 162b are formed in parallel in the vertical direction with an interval corresponding to the width of the solenoid 78. Positioning is automatically performed by engaging the two. In the normal state (demagnetized state), the solenoid 78 is connected to the plastic gear 7.
8a is raised by the force of the return spring 78b,
As a result, the end locking portion 7 of the stopper lever 76
6a is biased toward the main shaft side and comes into contact with the outer periphery of the ratchet portion 72d of each rotation display 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 removed from the outer periphery of the ratchet portion 72d. 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. A window 79 is formed in the upper part of the rear wall 61e corresponding to the rear end of the stopper lever 76, and the interior of the variable display mechanism 60 can be adjusted through the window 79. . Window part 79
Usually, a lid 80 is engaged and locked with elastic locking pieces 80a at both ends, and a light-shielding seal or the like is pasted on top of the lid 80 to prevent light from leaking inside. .

On the other hand, on the inner surface of the side wall 61d, there are a plurality of holes (five in the drawing) located on a concentric circle centered on the through hole 63 through which the main shaft 64 is inserted.
A light projecting section 81 is provided respectively. Light projecting section 81
consists of a through hole and a cylindrical part protruding inward from the side wall along the periphery of the through hole, and a light emitting element 83 held on a light projecting board 82 in a corresponding arrangement within each light projecting part 81, The light projection board 82 is inserted from the outside of the side wall 61d and 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, there is a cylindrical light receiving part 8 disposed symmetrically with the light projecting part 81.
A light-receiving substrate 87 having a light-receiving element 86 incorporated therein is fixed with a screw or the like.

When the ball hits the specific winning hole 7 or 8, the solenoid 78 is energized, and the stopper lever 76 is activated.
The three rotation display members 72 rotated by the removal of the solenoid 78 are stopped by the stop switch 30 cutting off the power to the solenoid 78 and the stop lever 76 being engaged with the ratchet portion 72d. When the numbers or patterns on the surface of each cylindrical display section 72c are aligned in a predetermined 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 main 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 passes through each light guide section 72e, reaches the light receiving element 86, and is detected. As a result, the three rotation display members 72
It is detected that the numbers or patterns on the surface of the ``are in a predetermined state (occurrence of a specific condition), and the variable winning device 5 is operated for a certain period of time (e.g. 30 seconds) or until a predetermined number (e.g. 10) of winning balls are received. A special gaming state called a "jackpot" can be generated in which this is repeated a plurality of times (for example, 10 times) by opening the opening and fulfilling the continuation condition (winning in the special winning hole 5c).

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

Further, on the lower surface of the upper wall 61a, there are two cylindrical display sections 72c on the left among the three rotating display members 72.
A rotational position detector 91 consisting of two reed switches or the like is attached by a mounting board 92 corresponding to the magnet 90 embedded in the magnet 90 . 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, a mid-win state is generated which provides a smaller profit than the above-mentioned jackpot state, for example, such that the variable prize winning device 5 is kept 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 rotation display member 7
A light guide section 7 parallel to the main shaft 64 is located inside the main shaft 64.
2e, and a light projecting section 81 and a light receiving section 85 are provided at both ends thereof.
Detection is performed by arranging the detectors to face each other and providing a detection optical axis parallel to the main shaft. 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 from there will be perpendicular to the detection optical axis, so there will be no malfunction of the detector. do not have. However, in the above embodiment, the void C ₂
Since the rotation of the rotation display member 72 is prevented by entering the tip of the stopper lever 76 into the inner ratchet portion 72d and engaging it with the inner ratchet portion 72d, the gap _C2 cannot be made so small. As a result, the detector may malfunction due to the light entering through the gap _C2 . However, the void
By entering the stopper lever 76 into _C2 and stopping the rotation, it is possible to prevent the stopper lever 76 from moving in the lateral direction, thereby preventing the stopper lever from falling off.

Therefore, in this embodiment, the stopper lever 76 is prevented from falling off by entering the stopper lever 76 through _the gap _C2 and stopping its rotation. was avoided as follows.

That is, a first end-forming cavity _E1 is formed inside the cylindrical display portion 72c of each rotating display member 72,
and the outer diameter of the ratchet portion 72d is the cylindrical display portion 7.
Form a gap C ₃ smaller than the inner diameter of 2c,
By exposing the ratchet portion 72d into the first end forming cavity _E1 , a weighted portion _F1 is created between the cylindrical display portion 72c and the ratchet portion 72d. Further, a second unformed portion _E2 is formed inside the ratchet portion 72d, and a cylindrical light receiving portion is formed in the second unformed space _E2 of the rotary display member 72 on the light receiving portion side (leftmost side). A weighted portion _F2 is formed between the rotary display member 72 and the ratchet portion 72d by facing the _tip of the rotary display member 85. The tip of the light guide section 72e of the second rotary display member 72 is exposed and slightly overlaps with the ratchet section 72d.

This makes it very difficult for light entering from the gap between the leftmost rotating display member 72 and the light receiving section 85 and the gap _C2 between each rotating display member 72 to reach the light receiving element 86 in the light receiving section 85. As a result, malfunctions of the detector can almost certainly be prevented. Further, by providing the unformed cavities E ₁ and E ₂ , 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 outwardly from the normal line G in the radial direction, and this engaging surface 172a.
a reinforcing surface 172b that is substantially perpendicular to the reinforcing surface 172b, and a communicating surface 172c that reaches the base of the engagement surface 172a at a gentle inclination angle from the reinforcing surface 172b.
A chevron-shaped pawl 172 consisting of is continuously formed along the circumferential direction. The number of claws 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.

Subshaft 7 that holds stopper lever 76
7 is disposed a distance L outside an extension of a tangent H that is orthogonal to the normal G passing through the center of the ratchet portion 72d. As a result, the stopper lever 76 is moved to the ratchet portion 72 by the solenoid 78.
When rotating in the direction away from d, the tip locking portion 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. As a result, the frictional force between the distal end locking portion 76a of the stopper lever 76 and the ratchet portion 72d when the stopper lever 76 is disengaged is reduced, and the stopper lever can be removed with a relatively light force.

Furthermore, the end locking portion 76 of the stopper lever 76
a is engaged with the ratchet portion 72d, and the pawl 1
An engagement surface 172a and a communication surface 172c forming a
It is shaped to fit snugly into the angle formed by the two. As a result, the ratchet portion 7
2d, the rotation of the locking portion 76a is stopped once, and then the locking portion 76a disengages from the pawl 172 and then engages with the next pawl again to prevent the locking portion 76a from stopping twice. Wear of the mating surface 172a and the communicating surface 172c 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 a relay board 93 that constitutes a repeater is attached to the lower surface of the lower wall 61b that constitutes the frame 61 of the variable display mechanism section 60 configured as described above. This relay board 93 includes the rotation driving means 67 provided in the variable display mechanism section 60, a rotation stop solenoid 78, and a light projecting board 8 that constitutes a specific mode occurrence detector (big hit, medium hit detector).
2 and plugs 94a, 9 at the end of each lead wire pulled out from the light receiving board 87 and the rotational position detector 91.
Terminal block 9 for inserting 4b, 94c, 94d
5a, 95b, 95c, and 95d are provided. After the lead wires are once assembled on the relay board 93, the back component board 50 is connected to the back component board 50 by a bundle of connection wires 96 connected to each terminal block 95a to 95d.
CPU via a second relay board 97 provided in
It is designed to be connected to a control board 98 equipped with a control circuit consisting of the following (see FIG. 10).

This makes it easier to handle the lead wires drawn out from the variable display mechanism section 60, which has a large number of electrical drive sources and detectors, when assembling the variable display mechanism section. The lead wire of the variable display mechanism section will not get entangled with parts such as the ball dispensing device. In addition, since each lead wire is connected to the control board 98 via the second relay board 97 after collecting the lead wires into a bundle of connection wires 96, the control board 98 after the variable display mechanism is assembled.
Electrical connection work can also be done very easily.

Further, the terminals (pins) 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.

In addition, since the relay board 93 is attached to the lower wall 61b of the variable display mechanism section 60, a sufficient distance from other parts is ensured. Heat is radiated sufficiently 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, and the variable display mechanism section 60 is installed here.
A connecting wire 96 is extended and connected from the first relay board 93 mounted on the lower surface of the lower wall 61b. The second relay board 97 has
In addition, lead wires from the lighting means 25 on both sides, solenoids 56 disposed at the bottom of the back component board 50, specific winning detectors 33, 34, etc. are also connected to the second relay board 97. The control board 98 is electrically connected 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 disposed above the rear end of the transmission member 5d connected to the transmission member 5c (see FIG. 2) so as to face it.

[Operation/Effect] As explained above, this invention has a plurality of rotating display members (rotating drums) attached around one shaft so that they can follow rotation and idle rotation, and this shaft is rotated by a motor. At the same time,
Between the motor and the shaft, there is a first speed change section that reduces the rotational speed of the motor and increases the driving force, and a second speed change section that converts the circumferential speed of the rotation display member attached to the shaft to an appropriate speed. The rotating display member is rotated at such a speed that the player can barely discern the numbers and patterns displayed by staring at the surface of the rotating display member. Due to the effect that it is not possible to consciously cause a specific pattern to occur at the timing of the operation, both experts and beginners are given the same chance of generating a specific pattern, ensuring fairness in the game, and pachinko game parlors. It is possible to prevent unexpected disadvantages. In addition, since the numbers and patterns on the surface can be barely discerned during rotation, it increases the player's ability to concentrate on the variable display device, induces a psychological state in which certain aspects are more likely to occur, and reduces the player's desire to play. This has the effect of preventing the decline of

In addition, since a first transmission section is provided between the main shaft and the motor that reduces the rotational speed of the motor and increases the driving force, it is possible to rotate the main shaft using a small motor with relatively low drive power. This effect has the effect that the variable display mechanism section can be configured compactly. Furthermore, by changing the gear ratio of the driving gear and the driven gear constituting the first transmission section or the second transmission section, the circumferential speed can be easily adjusted to the above-mentioned appropriate speed according to the outer diameter of the rotation display member. You can adjust it to
