Description

[Detailed Description of the Invention] [Field of Application] The second invention is provided within the gaming area of a pachinko gaming machine,
The present invention relates to a technique that is effective when used in a variable display device that is activated by the winning of a game ball into a specific winning opening.

[Prior Art] Pachinko gaming machines dynamically change the game content to increase the interest of the game.

In order to temporarily increase the winning probability and improve the service to players, various electric winning devices called so-called yakumono have been developed. Pachinko gaming machines have been proposed that are activated by the winning of a game ball into a winning slot and are equipped with a variable display device or the like that generates a specific form called a jackpot, although the occurrence rate is relatively low.

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 that is stopped by an automatic stop using a stop switch or a timer, and a specific state (jackpot state) occurs when the combination of numbers that can be set in the stopped state becomes a specific preset combination. A display device and several (for example, three) drums with multiple numbers and patterns attached to the outer periphery are rotated by winning a prize in a specific winning slot and stopped in order with a stop switch or timer, and the numbers in the stopped state are displayed. There has been provided a so-called rotary drum type variable display device that generates a specific mode depending on a combination of images and pictures.

[Problem] In the rotating drum type variable display device described above, each drum is stopped in sequence in order to make the arrangement of numbers and pictures on the surface of each drum different each time after the drum is stopped, in other words to provide randomness to the display. I try to let them do it. In this case, if each drum is provided with a rotational drive source such as a motor so that each drum can rotate and stop independently, the entire apparatus will become larger. Therefore, each drum is fitted so that it rotates around a common rotation axis using frictional force, and is driven to rotate by a single drive source, and when stopped, each drum is stopped in turn using separate stopping means. It is possible that In this way, the entire device can be constructed relatively compactly.

However, on the other hand, when such a rotation stopping method is applied, it is necessary to engage an appropriate lever from the outside to stop the rotating drum at an accurate position. As a result, the stop lever may come off, the drum may stop at a position other than the normal stop position, or the drum may stop twice, such as once the drum is about to stop, rotate again to the next stop position, and then stop, or the stop lever may come off. The frictional force generated when the drum is brought into contact with the drum and stopped causes wear, and long-term operation may reduce the reliability of stopping.

[Objective of the Invention] An object of the present invention is to provide a rotating drum type variable display device that can stop the rotating drum at an accurate position and reliably, has little wear on each friction part, and has a relatively small size. It is an object of the present invention to provide a rotation stopping means that can engage and disengage a stopping lever using a driving force.

[Means for Solving the Problem] The present invention forms a ratchet portion having an unformed cavity inside on one side of the main wall of a rotary display member having a cylindrical display portion on the periphery, and the outer periphery of the ratchet portion. includes an engaging surface extending approximately in the radial direction, a reinforcing surface substantially perpendicular to the engaging surface at its outer tip, and a connecting surface linearly connecting this reinforcing surface and the base of the next engaging surface. A plurality of claws are formed, and a stop lever rotated by an actuation source provided for each rotation display member is mounted around an axis parallel to the main shaft that supports the rotation display member. One end of this stop lever was exposed from the gap between each rotation display member and removably engaged with the outer periphery of the ratchet portion. This makes it possible to stop the rotation display member at an accurate position and reliably, and also allows the stop lever to be engaged and disengaged with relatively little driving force, with little wear on each friction part. This achieves the above purpose of doing so.

[Example 1] Figure 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 Figure 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, due to the occurrence of a specific aspect in the variable display bag [4] A variable winning device that converts into a winning area! 5 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. Further, general winning holes 5b are provided on both sides of the variable winning prize-[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 guiding members 13a and 13b arranged in an arc shape with an interval of one ball.
The lower half has a ball receiving part 7a projecting into the game area, and direction setting guide members 13a, 13b.
All the batted balls that pass through the space enter through the semi-cylindrical opening forming the specific winning hole, pass through the winning ball exit path formed to penetrate the game board, and are collected to the back of the game board and detected. The second specific winning hole 8 consists of a winning tool called a winning chatker that opens upward into the gaming area.

Above the game board 1, there is a so-called "heaven" winning opening 6a consisting of a winning chatker, and a left jack hole j1. Winning holes 6b and 6c are provided on the right side of the top.Furthermore, tulip-type batted ball winning devices 9 are arranged diagonally downward and outward of 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 center line CC' 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 ball that is guided by the direction setting guide member 13a and flows down can be controlled by the variable display bag [
It becomes easier to be guided toward the AC surface on the front of the variable display device 4, and the probability of winning a prize in the specific winning opening 8 provided below the variable display device 4 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.

Between the second specific winning opening 8 and the variable winning device 5 is a variable winning bag! ! ! A downstream guide member 15 is disposed to form a V-shaped flow path (indicated by broken lines in FIG. 2) that guides the batted ball toward the winning opening of No. In correspondence with the two types of winning holes of the device 5, the batted balls are distributed to those winning holes, and the variable winning device i! A distribution guide member 16 is provided to reduce the speed of the winning ball into the ball.

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 hit ball enters 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.

Direction setting guiding members 1 arranged on both sides of the center of the game board 1
In the non-gaming space, the upper half of which is surrounded by 3c, through which most of the batted balls do not pass, there is provided a lighting means 25 that blinks or lights up when a specific mode occurs due to the stoppage of the variable display operation of the variable display device 4. . Further, on the upper part of the game board 1, a prize ball lamp 21 and a variable display device 4 are provided which are temporarily turned on when a ball hits a winning hole such as the sky prize openings 6a to 6c or the tulip type hit ball winning device 9. A turbo lamp 22 that lights up or flashes when a specific condition occurs due to the stoppage of the variable display operation, a segment type display 23 that displays the number of winning batted balls when the variable prize winning device 5 is opened, and a predetermined number. A display member 20 is provided with a completion lamp 24 that indicates the end of the game when all winning balls have been paid out.

Furthermore, on both sides of the variable prize winning device 5, there are lighting devices 28 that are turned on or blinked when a jackpot occurs.

In addition, in the special winning opening 5C, there is a continuation condition fulfillment indicator 29 that lights up when the continuation condition is satisfied due to a winning there, and furthermore, at the bottom of the variable winning device 5, it detects a batted ball that has won a prize while the variable winning device is open. A count detector 32 is provided.

Note that the lighting means 2 on one side of the game board 1 (the right side in the figure)

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.

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.

It is inserted from the front into the storage chamber IA at the center of the game board.

The game board 1 corresponds to the front component board 40 to be fixed.
A substantially rectangular back surface component board 50 is attached to the back surface of the . An opening 50a corresponding to the display head 45a of 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 top and both ends of the back component substrate. Upright walls 51 and 52 are formed to have a similar effect.

The upstanding wall 51 formed on the side facing the back surface of the game board 1
．． 52, on the front side of the back component board 50, there is a guide path 53 for guiding the batted balls that hit the Tennin prize holes 68 to 6c, and a guide path 53 for guiding the batted balls that hit the winning holes 68 to 6c, and a guide path 53 that guides the batted balls that hit the winning holes 68 to 6c, and the left and right specific winning lowers. A pair of guide paths 54 for guiding the batted ball and a guide gutter 55 for guiding the batted ball that has won into the lower second specific prize opening 8 are 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,
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 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. 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 component board 50, and a variable display mechanism section 60 is fixed to the mounting receptacles 59 by mounting sections 60a provided on the upper and lower walls. 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 in 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 61a that are separably connected to each other. It is already configured.

Among the above walls, the upper wall 61a and the lower wall 61b.

Standing portions 6 each having attachment holes 62a along both side edges.
2 is provided, and the ends of the side walls 61c and 61d are brought into contact with this upright wall 62, and screws are inserted from the sides to secure the mounting holes 6.
By screwing into 2a, the upper wall 61a, the lower wall 61b, and the side walls 61c, 61d are integrated. The rear wall 61e has an upright portion 62 having attachment holes 62b formed on both side edges of the upper wall 61a, the lower wall 61b, and the side walls 61c, 61.
It is fixed by engaging the rear end opening of d and screwing a screw into the mounting hole 62b from the outside of the side walls 61c, 61d.

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.

Three sets of retaining rings 71a and 71b made of E-shaped rings are attached to a groove 64b formed on the outer periphery of the main shaft 64, and between each set of retaining rings 71a and 71b there is a cylindrical rotating A 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, a ratchet section 72d formed on the outer wall of the main u72b, and the main wall. A plurality of light guide portions 72 formed on the inner surface of 72b
It is composed of e.

The retaining rings 71a and 71b are respectively connected to the rotation display member 7.
The washer 73 is fitted onto the shaft 64 so as to be in contact with one of the stop shafts 71b. and,
A compression spring 74 is inserted between the washer 73 and the base of the main wall 72b of the rotation display member 72, and the repulsive force of the compression spring 74 causes the stopper 71a to
Frictional force is generated on four contact surfaces: between the spring 74 and the main W72b, 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 retaining rings 71a and 71b, and the adjacent pairs of retaining rings 71b and 71a have a gap C1.
Frictional force acts only on one side of each stopper 71a, 71b. Therefore, idle rotation of each stopper 71a, 71b is prevented.

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 stop shaft, which is simply fitted onto the outer periphery of the shaft, may be rotated idly.

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 retaining rings 71a of each set is set wider than the width of the cylindrical display portion 72c of the rotation display member 72, so that there is a gap between each cylindrical display portion 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.
Three stopper levers 76 are arranged at the rear of the main shaft 64, and these stopper levers 76 are rotatably supported by a sub-shaft 77 that extends horizontally between the side walls 61e and 61a in parallel with the main shaft 64. . Furthermore, three solenoids 78 are attached to the inside of the rear wall 61e in order to rotate the stopper levers 76 in correspondence with each other, and the tip of the plunger 78a of each solenoid 78 is pinned to the rear end of the stopper lever 76. etc. are connected.

On the inner surface of the rear wall 61e, three sets of rib-shaped guide parts 162a, 162b are formed in parallel in the vertical direction with an interval corresponding to the width of the solenoid 78, and these guide parts 162a,
Positioning is automatically performed by engaging the solenoid 78 between 162b and 162b. In the normal state (demagnetized state), the solenoid 78 is connected to the plunger 7.
8a is raised by the force of the return spring 78b, whereby the distal end locking portion 76a of the stopper lever 76 is urged toward the main shaft side and comes into contact with the outer periphery of the ratchet portion 72d of each rotation display member 72. 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 one 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 1a, and this window 7
9, the interior of the variable display mechanism section 60 can be adjusted. A lid 80 is normally engaged with the window portion 79 and locked with elastic locking pieces 80a at both ends, and a light-blocking sticker or the like is pasted on top of the lid 80 to prevent light from leaking inside. be done.

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 part 85 arranged symmetrically with the light projecting part 8 is formed, each having a light receiving element 86 incorporated therein. A substrate 87 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 30 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 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 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). A special game state called a "jackpot" is created in which the winning balls are opened until there are (for example, 10) winning balls, and this is repeated multiple times (for example, 10 times) if the continuation condition (winning into the special winning hole 5c) is met. can be done.

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, a mid-win state is generated which gives 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 light guide section 72e is provided inside the rotating display member 72 and is parallel to the main shaft 64, and the light projecting section 81 and the light receiving section 85 are arranged to face each other at the end of the surface of the light guide section 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 72c of each rotary 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 into the first unformed space E1, a weight part F1 is created between the cylindrical display part 72c and the ratchet part 72d. Furthermore, a second unformed cavity E2 is formed inside the ratchet part 72d, and a cylindrical light receptor Ratchet part 72d with the tip of 85 facing
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 portion 72d, the distal end locking portion 76a is rotated so as to move away from the direction aG, but not in the direction aG. 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 end locking portion 76a of the stopper lever 76 and the ratchet portion 7
2d is reduced, and the stopper lever can be removed with relatively light force.

Further, 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 communicating 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 New Year's solenoid 78 provided in the variable display mechanism section 60.
, a plug 94 a at the end of each lead wire pulled out from the light emitting board 82, the light receiving board 87, and the rotational position detector 91 that constitute the 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, as well as 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 in the upper left corner of the back side configuration board 50 attached to the back side of the game board 1, and the first relay board 97 attached to the lower surface of the lower wall 61b of the variable display mechanism section 60 is placed here. A connecting wire 96 is extended from the relay board 93 to be connected.Second relay board 9
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 rt33, 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.

FIG. 11 shows the control of the entire pachinko game machine equipped with the variable display device configured as described above, that is, the various displays provided on the game board, the drive source of the variable display device, the special variable prize winning device, the speaker, etc. An example of a control circuit is shown.

The switches SWI to SW4 forming input signals to the control circuit of this embodiment are the start switch, that is, the specific winning detector 33, 34, the detector in the variable display stop means 30, and the detector in the special variable winning device 5 in the above embodiment, respectively. This detector corresponds to the specific condition configuration detector 31 and count detector 32 of .

In addition, an LED driven by the output signal of this control circuit
The lamps LED1 to LED4 correspond to the storage display means 49 for specific winning balls in the embodiment. Similarly, the solenoids 5oL1 to 5oL4 correspond to the rotation stop solenoid 78 in the variable display device 4 and the drive source 56 for the special variable prize winning device 5 in the embodiment, respectively.

The control device shown in FIG. 11 is constructed using a program storage type CPU (central processing unit: microcomputer) 210 implemented as a semiconductor integrated circuit device.

That is, the control device shown in FIG. 11 includes the CPU 210,
ROM (read-only storage device) 220. RAM (Random Access Memory) 230. Address decoder 24
0. l10 (input/output) unit 250, clock signal generation means 280. Reset signal generating means 290. It is composed of an address bus LA, a data bus LD, a logic gate 61, and the like.

CPtJ210 has an 8-bit type (model number: Z
80) is used. This C:PU210 has address terminals (Ao to A1g) and data terminals (Do=D7).
, a read control terminal RD, a write control terminal WR, a clock terminal GK, and a reset terminal R.

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 the address data (Ao to A11) output from the CPU 210 to create 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)
The six signals (RD/WD) issued from 210 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 (S 8 , S 9 ) is stored in the ROM 22 mentioned above.
0 and is used as a chip select signal for the RAM 230. Further, other selection signals 81 to S7 are used to control input/output circuits in the work/○ unit 250, which will be described later. In other words, a so-called memory mapped/○ method is adopted in which input/output channels are arranged in an address space. By adopting this memory Matsubuto I/○ method, any input/output circuit can be accessed by simply accessing a specific address without the need for complex procedures such as opening and closing input/output channels. It is designed to perform input/output operations.

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 CK 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. This reset signal generating means 290 is constructed simply and on a small scale using a counter or the like.

In this case, the reset pulse φt has a duty width, that is, a pulse width that is long enough to reliably reset the CPU 210. Also,
The pulse generation interval, that is, the period, is determined by the CPU 210.
is set so that the processing time is reliably longer than the processing time for executing the program instructions stored in the ROM.

Furthermore, since the reset interval of the CPU 210 is a constant cycle, the number of resets is stored in the RAM 230, thereby forming a so-called soft timer function.

Next, the I10 unit 250 has buffer gates 251 . Latch circuits 252-256 are provided. These input/output circuits (251 to 256
) The operation is controlled by the selection signals 81 to S6 mentioned above. Further, each input/output circuit (251 to 256) is connected to the CPU 210 via a data bus LD. Data exchanged between the pachinko game machine main body 300 side and the control device side is placed on the data bus LD. Furthermore, the above input/output circuit (251-2
56), a scale generating means 257 is provided. The operation of this scale generating means 257 is controlled by a selection signal S7.

Among the input/output circuits (251 to 256), the buffer gate 251 constitutes an input circuit. This buffer gate 25
1 receives detection signals from various detection means (SWI to SW4, etc.) provided on the pachinko gaming machine main body 300 side, and puts them on the data bus LD within the control device 200. In this case, the detection means is the start switch S mentioned above.
W.I.

Stop switch SW2. Continuation condition detection switch SW3
．． 10 count detector SW4 and a detector (83
, 86) and a rotational position detector 91.

Furthermore, among the input/output circuits (251 to 256), latch circuits 252 to 256 form output circuits.

Furthermore, the latch circuit 254 therein includes a decoder. This decoder decodes each display data of the light emitting diode type segment type display 23, 45c on the pachinko game machine main body 300 side. The display data is sent to the CPU 21 via the data bus LD. Given by O.

The functions of each output circuit (252-256) are as follows.

That is, the latch circuit 252 forms a drive signal for the motor 67a that rotates the main shaft 64 having the rotary display member 72 of the variable display device 4 described above. The latch circuit 253 operates a solenoid 78 (SoL1
~5oL3) drive signal is formed. Incidentally, each of the latch circuits 252 and 253 is attached with a driver 262, 263, respectively, for increasing the driving force of its output.

The latch circuit 254 is connected to the segment type display devices 23 and 4.
5c is displayed. As mentioned above, the display 23 displays "the number of winning balls during one opening operation of the variable prize winning device 5 when a specific form of jackpot J occurs," and the display 45c displays "the number of winning balls during one opening operation of the variable prize winning device 5 when a specific form of jackpot J occurs." This displays the number of times that the continuation condition is met. The display data is given from the CPU via the data bus LD.

The latch circuit 255 individually drives the memory display lamps LEDI to LED4 made of light emitting diodes to turn on. Control data for the lighting is given from the CPU via the data bus LD. The memory display lamps LED 1 to LED 4 are used, as described above, to display the number of reserved batted balls that have won the specific prize lower, 8 (FIG. 2).

The latch circuit 256 individually drives the drive source and display means on the pachinko game machine main body 300 side via the driver 266. In this case, the drive source is the electromagnetic solenoid 56 (FIG. 5) that drives the above-mentioned special variable winning device 5 to open, and the display means is the continuation condition fulfillment display unit 29 (second Figure).

Furthermore, the scale generating means 257 generates a sound source having a predetermined scale when the rotary display member 72 in the variable display device 4 rotates or when a "big hit" or "medium hit" occurs. The generated sound source is amplified by the amplifier 267 and sent to the pachinko machine main body 3.
It is given to the speaker SP for generating sound effects on the 00 side. The scale of this sound source is set by data given from the CPU via the data bus LD.

[Function/Effect] This invention forms a ratchet part having an unformed cavity inside on one side of the earthen wall of a rotating display member (rotating drum) having a cylindrical display part on the peripheral edge, and The outer periphery of the part includes an engaging surface extending approximately in the radial direction, a reinforcing surface substantially perpendicular to the engaging surface at its outer tip, and a linear connection between this reinforcing surface and the base of the next engaging surface. A plurality of claws each having a connecting surface are formed, and a stopper lever is rotated by an actuating source provided for each rotation display member around an axis parallel to the main shaft supporting the rotation display member. When the stopper lever is mounted, one end of the stopper lever faces through the gap between each rotation display member and is removably engaged with the outer periphery of the ratchet part, so that when the stopper lever is engaged with the ratchet part, the tip of the stopper lever is exposed to each rotation. The stopper lever is prevented from moving in the left-right direction (axial direction) by entering the gap between the display members, and the tip of the stopper lever is tightly joined to the engagement surface of the pawl of the ratchet part when engaged. The rotation display member is prevented from coming off the ratchet portion, and the rotation display member can be reliably stopped.

In addition, a reinforced surface is formed at the tip of the pawl on the outer periphery of the ratchet part, and the tip of the stopper lever moves while making surface contact with the communication surface formed from the reinforced surface to the base of the engagement surface of the next pawl. Therefore, there is less wear on the ratchet portion, so-called double-stopping can be prevented, and the rotating display member can be stopped reliably even after long-time operation.

Furthermore, the sub-shaft that supports the stopper lever is disposed outside the tangent line passing through the contact area between each pawl of the ratchet part and the tip of the stopper lever, so that when the stopper lever is released, the tip of the lever is in the ratchet rotation direction, that is, engaged. The effect of rotating the stopper lever toward the front of the surface has the effect that the stopper lever can be removed from the ratchet with a relatively small force.
