The present invention relates to a technique effectively used for a variable display device operated by winning a game ball to a specific winning opening.

[Prior Art] In a pachinko gaming machine, in order to enhance the interest of the game by dynamically changing the game content, and temporarily improve the winning probability to improve the service to the player.
Various electric prize winning devices called so-called winning items (yakumono) have been developed. For example, it is activated by winning a game ball into a specific winning opening provided in the game section, and the occurrence rate is relatively low. A pachinko game machine provided with a variable display device for generating a specific mode called a big hit has been proposed.

Conventionally, as the variable display device, a number, a code, a pattern, or the like displayed on a plurality of (for example, four) segment-type displays including LEDs are variably operated by winning a hit ball at a specific winning opening in a game area. Then, it is stopped by automatic stop by a stop switch or a timer, and when a combination of numbers in the stopped state becomes a preset specific combination, a specific mode (big hit state) is generated, so-called digital variable A display device and several drums (for example, three) with a plurality of identification marks such as numbers, symbols, and patterns attached to the outer periphery are rotated by a prize at a specific winning opening and stopped in turn by a stop switch or a timer. , A so-called rotary drum type variable display in which a specific mode is generated by a combination of numbers and patterns in the stopped state And the location are provided.

[Problem] However, the conventional rotary drum type variable display device is 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 of which is attached to the back of the game board. The front frame has a display window portion having substantially the same size as the mounting hole of the variable display device formed on the game board, and is mounted so as to be joined to the edge portion of the mounting hole.

Further, the main body portion covers the front of the plurality of rotary drums held inside with a semi-cylindrical transparent protective member, and the protective member is provided from the rear of the game board to the mounting hole and the display window portion of the front frame. It was attached so that it would engage and face the game area. Therefore, the display window portion of the front frame becomes very large and the strength of the front frame is lowered, and the durability against the collision of a hitting ball flowing down is low, and the amount of protrusion of the transparent protection member toward the game area side is small. As it becomes larger, it interferes with the exchange of the hit balls in the left and right game areas, that is, the hit balls passing through the front surface of the variable display device to the opposite side, and the specific winning opening arranged below the variable display device. There is a problem in that it is difficult to sufficiently increase the winning probability of hitting the variable winning device that is opened with the occurrence of the specific mode.

[Object of the Invention] An object of the present invention is to improve the durability of the variable display device by increasing the strength of the variable display device, particularly the front frame.

Another object of the present invention is to arrange a game ball flowing down in the left and right game areas of the variable display device under the variable display device by passing the front surface of the variable display device and frequently alternating current. It is an object of the present invention to provide a variable display device capable of increasing the winning probability of a specific winning opening or a special winning device.

[Means for Solving the Problem] This invention provides an armor member having a hitting ball guiding surface on the upper side of an alternating current surface that is substantially flush with the game board, and a recess forming wall projecting rearward inside the alternating current surface. A plurality of display window parts corresponding to the respective rotary display members (rotary drums) are provided at the rear end of the recess forming wall, and a continuous transparent protective member is joined to the back part of the display window parts. By fixing the display panel to form the front constituent substrate of the variable display device, the opening area of the display window portion is reduced and the peripheral edge of the display window portion is reinforced by the recess forming wall, the transparent protective member, etc. The strength of the front component board is increased, the durability of the variable display device is improved, and the amount of the transparent protective member protruding from the display window is reduced to frequently exchange game balls, resulting in specific prize holes and special prizes.

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

The variable display mechanism unit 60 is provided in a frame body 61 formed in a box shape with an open front surface by an upper wall 61a, a lower wall 61b, side walls 61c and 61d, and a rear wall 61e that are separably coupled to each other. It is configured.

Of the above-mentioned wall bodies, the upper wall 61a and the lower wall 61b are provided with upright portions 62 having attachment holes 62a along both side edges thereof, and the end portions of the side walls 61c and 61d are brought into contact with the upright portions 62. Then, the upper wall 61a, the lower wall 61b and the side walls 61c, 61d are integrated by inserting a screw from the side and screwing the screw into the attachment hole 62a. The rear wall 61e engages the upright portion 62 having the attachment holes 62b formed on both side edges thereof with the upper wall 61a, the lower wall 61b, and the rear end openings of the side walls 61c, 61d to form the rear walls 61c, 61d. The screws are fixed by screwing the screws into the mounting holes 62b from the outside.

A through hole 63 is formed at a position slightly forward from the center of the side walls 61c and 61d. Both end portions of a main shaft 64 are inserted into the through hole 63, and the main shaft 64 is located between the side walls 61c and 61d. It is designed to be rotatably supported. A pair of collars 64a are fitted to both ends of the main shaft 64, and the collars 64a are brought into contact with the side walls 61c and 61d to prevent axial movement, and one end of the shaft 64 has one side wall 61c. The driven gear 65 is mounted so as to project further. In addition, the side wall 61c has boss portions (4 pieces) 6 protruding outward.
6 is formed, and a storage case 68 holding a drive means 67 including a motor 67a and a first speed change portion 67b that slows down the rotation of the motor 67a is attached to the boss portion 66. A drive gear 69 is attached to the drive shaft 67c of the drive means 67,
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, and the second transmission portion 7 rotates this at the most appropriate rotation speed.
0 is configured.

The first transmission portion 67b can increase the rotational force of the motor 67a to smoothly rotate the main shaft 64. Also, a rotation display member 72, which will be described later, is mounted on the outer periphery of the main shaft 64 by the second speed change unit 70.
In the state in which the main shaft 64 is rotated, the main shaft 64 is rotated at a rotational speed at which the player can barely read the numbers and patterns on the surface.

In the groove 64b formed on the outer periphery of the main shaft 64, three sets of retaining rings 71a, 71b made of an E-shaped ring or the like are provided.
Is mounted, and a cylindrical rotation display member 72 is provided between the retaining rings 71a and 71b of each set.
Is rotatably fitted around the outer periphery of the.

The rotation display member 72 has the shaft portion 7 fitted to the shaft 64.
2a, a disc-shaped main wall 72b formed on the outer periphery thereof, a cylindrical display portion 72c formed on the outer periphery of the main wall 72b, and a ratchet portion 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 and.

The retaining rings 71a and 71b are respectively the rotation display member 7
The washer 73 is fitted to the shaft 64 so as to have a gap larger than the width of the second shaft portion 72a, and to come into contact with one of the retaining rings 71b. And
A compression spring 74 is inserted between the washer 73 and the base portion of the main wall 72b of the rotation display member 72, and the repulsive force of the compression spring 74 causes the retaining ring 71a and the shaft portion 72a.
Frictional forces are generated on the 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 retaining ring 71b. By these friction surfaces, the rotational force of the main shaft 64 is transmitted to the rotation display member 72, and when the rotation of the rotation display member 72 is forcibly stopped from the outside, slippage occurs on each friction surface and the main shaft The rotation of the rotation display member 72 can be stopped without stopping the rotation of 64.

Moreover, in the above case, since each rotation display member 72 is inserted between each pair of snap rings 71a and 71b, and the adjacent snap rings 71b and 71a have the gap C ₁ ,
Friction force acts on each of the retaining rings 71a and 71b only on one side. Therefore, the retaining rings 71a and 71b are prevented from idling. That is, when only one retaining ring is provided between the rotation display members 72 and the compression springs 74 are brought into contact with both side faces of the retaining ring, the frictional force acts on both sides of the retaining ring, and the frictional force increases. There is a possibility that the retaining ring simply fitted around the outer periphery of the shaft may idle.

In this way, the three rotary display members 72 are loosely fitted to the single main shaft 64 and are configured to follow and rotate by the frictional force, so that a rotary drive source is not provided for each rotary display member. , It becomes possible to stop the rotation of each independently. Along with this, the rotation display member 7
When 2 is forcibly stopped, slippage occurs at the four friction surfaces, causing the main shaft 64 to be idle, so that an unreasonable force does not act on the main shaft 64 and the load on the drive means 67 is small.

In addition, the spacing between the retaining rings 71a of each set is set to be wider than the width of the cylindrical display portion 72c of the rotation display member 72, so that there is a gap between the cylindrical display portions 72c when mounted on the shaft. C ₂ is generated, and the ratchet portion 72d can be exposed from the void C ₂ .

Then, the rotation display member 7 corresponds to the ratchet portion 72d.
Three stopper levers 76 are disposed behind the two, and these stopper levers 76 are rotatably supported by a sub-shaft 77 that extends horizontally between the side walls 61c and 61d in parallel with the main shaft 64. . Further, three solenoids 78 are attached to the inside of the rear wall 61e in order to rotate the stopper levers 76 corresponding to the stopper levers 76, and the tips of the plungers 78a of the solenoids 78 are pinned to the rear ends of the stopper levers 76. Are connected with each other.
On the inner surface of the rear wall 61e, three sets of rib-shaped guide portions 162a, 162b are formed in parallel in the longitudinal direction at intervals corresponding to the width of the solenoid 78.
Positioning is automatically performed by engaging the solenoid 78 between 162b. In the normal state (demagnetized state), the solenoid 78 has the plunger 7
8a is lifted by the force of the return spring 78b, whereby the tip end locking portion 76a of the stopper lever 76 is biased toward the main shaft side and abuts on the outer circumference of the ratchet portion 72d of each rotation display member 72. Prevent its rotation.

However, when the solenoid 78 is excited, the plunger 78a is lowered, the stopper lever 76 is rotated, and the locking portion 76a at the tip is lifted to move the ratchet portion 72d.
Is removed from the outer circumference of. As a result, the rotation inhibiting force of the ratchet portion 72d is released, and the rotation display member 72 rotates following the rotation of the main shaft 64.

In the above case, since the stopper lever 76 and the solenoid 78 for driving the stopper lever 76 are provided for each rotation display member 72, the rotation and the stop of the three rotation display members 72 can be independently controlled. As a result, irregularity is imparted to the arrangement of numbers and patterns on the surface of the rotation display member when rotation is stopped. A window 79 is formed in the upper portion of the rear wall 61e corresponding to the rear end of the stopper lever 76, and the inside of the variable display mechanism 60 can be adjusted from the window 79. There is. A lid 80 is normally engaged with the window 79 and is locked with elastic locking pieces 80a at both ends.
Further, by sticking a light-shielding seal or the like on top of it, light is prevented from leaking inside.

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 drawing) light projecting portions 81 are respectively provided so as to be located on a concentric circle centered on the through hole 63 through which 4 is inserted. The light projecting portion 81 is composed of a through hole and a cylindrical portion projecting inwardly of the side wall along the periphery of the through hole, and the light emission is held in each light projecting portion 81 by the light projecting substrate 82 in a corresponding arrangement. The element 83 is inserted from the outside of the side wall 61d to fix the light projecting substrate 82 with screws or the like. Further, a cover 84 that covers the periphery of the light projecting substrate 82 and prevents light from entering the inside is attached to the outer surface of the side wall 61d.

On the inner surface of the side wall 61c facing the light projecting portions 81,
A cylindrical light receiving portion 85 is formed symmetrically with the light emitting portion 81,
Light receiving substrate 8 having light receiving elements 86 incorporated therein
7 is fixed by screws or the like.

The solenoid 78 is excited by the winning of a ball hitting the specific winning opening 7 or 8, and the three rotation display members 72 rotated by the removal of the stopper lever 76 are energized to the solenoid 78 by the stop switch 30. When it is shut off and stopped by the stopper lever 76 engaging with the ratchet portion 72d, each cylindrical display portion 7
The arrangement of the surface of the cylindrical display portion 72c is determined in advance so that the light guide portions 72e inside the main wall 72b coincide with each other when the identification marks such as numbers, signs, and patterns on the surface of 2c are aligned in a predetermined state. Has been done. Therefore, when is stopped in a predetermined state, the light guide portions 72e of the rotary display members 72 are aligned on the detection optical axis of any one of the light emitting element 83 and the light receiving element 86.

Then, the light emitted from the light emitting element 83 is transmitted to each light guide portion 72.
It passes through e, reaches the light receiving element 86, and is detected. As a result, the numbers and symbols on the surface of the three rotation display members 72,
It is detected that the identification marks such as patterns are in a predetermined state (occurrence of a specific mode), and the variable winning device 5 is opened for a fixed time (for example, 30 seconds) or a predetermined number (for example, 10) of winning balls. And continuation condition (winning at special winning opening 5c)
Depending on the establishment of the above, it is possible to generate a special game state called “big hit” in which this is repeated a plurality of times (for example, 10 times).

In this embodiment, five sets of light emitting and light receiving elements 83 and 86 can detect several kinds of specific modes.

Furthermore, the three rotation display members 7 are provided on the lower surface of the upper wall 61a.
Corresponding to the magnet 90 embedded in the two left cylindrical display portions 72c of the two, a rotational position detector 91 including two reed switches and the like is attached by an attachment substrate 92. If the two magnets 90 are 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 which is smaller than the big hit state
It is designed to generate a medium hit state, which gives a profit such that it is opened for a short time.

Next, the method of detecting the occurrence of the above-described specific mode will be described in more detail.

In this embodiment, as described above, the light guide portion 72e parallel to the main shaft 64 is provided inside the rotation display member 72, and the light projecting portion 81 and the light receiving portion 85 are opposed to each other at both ends thereof so as to be parallel to the main shaft. A detection optical axis is provided for detection. Therefore, in principle, the light orthogonal to the detection optical axis does not hinder the detection. Therefore, if the space C ₂ between the three rotation display members 72 attached to the main shaft 64 is sufficiently small, the light entering from the space C ₂ is orthogonal to the detection optical axis, and thus the detector does not malfunction. . However, in the above embodiment, the stopper lever 7 is provided in the gap C _2.
Since the rotation of the rotation display member 72 is blocked by allowing the tip of the blade 6 to enter and engage with the inner ratchet portion 72d, the gap C ₂ cannot be made so small. As a result, the detector may malfunction due to the light entering through the space C ₂ . However, the effect of preventing detachment of the stopper lever to prevent lateral movement of the stopper lever 76 by taking a method of stopping the rotation by advancing the stopper lever 76 in the gap C ₂ is obtained.

Therefore, the stopper lever 7 from the gap C ₂ In this example
By adopting the method of inserting 6 to stop the rotation, while preventing the stopper lever 76 from falling off,
The malfunction of the detector due to the entry of light from the space C ₂ was avoided as follows.

That is, the first unformed empty portion E ₁ is formed inside the cylindrical display portion 72c of each rotation display member 72, and the outer diameter of the ratchet portion 72d is smaller than the inner diameter of the cylindrical display portion 72c by a gap C _3. By making the ratchet portion 72d small so as to face the inside of the first unformed empty portion E ₁ , a weight portion F ₁ is generated between the cylindrical display portion 72c and the ratchet portion 72d. Further, a second unformed empty portion E ₂ is formed inside the ratchet portion 72d, and a cylindrical light receiving portion is formed in the second unformed empty portion E ₂ of the rotation display member 72 on the light receiving portion side (the leftmost side). Ratchet part 72 with the tip of part 85 facing
A weight portion F ₂ is generated between d and
The second unformed space E _{2 of the} third and third rotation display members 72
The light guide portion 72e of the first and second rotation display members 72.
The front end of the ratchet is faced so as to slightly overlap the ratchet portion 72d.

Accordingly, the leftmost rotation display member 72 and the light receiving unit 8
Gap and light entering from the gap C ₂ between the rotational display members 72 and 5, is hardly very reach the light receiving element 86 in the light receiving portion 85, as malfunction of the detector is almost certainly prevented Has become. Further, by providing the unformed empty portions 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, the 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.

On the outer periphery of the ratchet portion 72d, as shown in an enlarged view in FIG. 9, an engagement surface 172a inclined slightly outside the normal line G in the radial direction, and a reinforcement forming a right angle with the engagement surface 172a. A chevron-shaped claw 172 is continuously formed along the circumferential direction, which includes a surface 172b and a connecting surface 172c reaching the base of the engaging surface 172a with a gentle inclination angle from the reinforcing surface 172b. The number of claws 172 on the outer circumference of the ratchet portion 72d is the same as the number of identification marks such as numbers, symbols, and patterns attached to the surface of the cylindrical display portion 72c.

The sub-shaft 77 holding the stopper lever 76 has a tangent line H orthogonal to a normal line G passing through the center of the ratchet portion 72d.
It is arranged at a distance L outside the extension line. As a result, when the stopper lever 76 is rotated by the solenoid 78 in the direction away from the ratchet portion 72d, the distal end locking portion 76a is rotated not in the direction of the normal line G but outside thereof. Therefore, when the stopper lever 76 is disengaged from the ratchet portion 72d,
The claw 172 is rotated outward while moving in the front direction, that is, in the moving direction. As a result, the frictional force between the tip locking portion 76a of the stopper lever 76 and the ratchet portion 72d at the time of disengagement is reduced, and the stopper lever can be removed with a comparatively light force.

Further, the tip end locking portion 76a of the stopper lever 76 is shaped so as to be closely engaged with the angle formed by the engaging surface 172a forming the pawl 172 and the connecting surface 172c in the engaged state with the ratchet portion 72d. Has been formed. By this, the rotation of the ratchet portion 72d is surely stopped, and once it is stopped, the locking portion 76a is disengaged from the claw 172 and is again engaged with the next claw, so that the so-called double stop is prevented and the engagement is performed. , The engaging surface 172a and the connecting surface 1 at the time of disengagement
Wear of 72c is suppressed, and displacement due to vibration at the time of engagement is prevented.

Further, since the reinforcing surface 172b is formed at the tip of the claw 172, the claws of the claw are less likely to be scraped off than when the tip has an acute angle. Therefore, even if frequent engagement / disengagement operations are repeated for a long period of time, wear is small and a reliable stop is guaranteed.

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 unit 60 configured as described above. On the relay board 93, the rotation driving means 67 and the rotation stopping solenoid 78 provided in the variable display mechanism section 60, and a light projecting board 82 constituting a specific mode occurrence detector (big hit, medium hit detector). Plugs 94a, 94b, 94 at the end portions of the lead wires drawn from the light receiving substrate 87 and the rotational position detector 91
terminal blocks 95a, 95b, 9 for inserting c, 94d
5c and 95d are provided. Then, the relay board 93
After assembling the lead wires to the terminal blocks 95a to 9a
By a bundle of connecting lines 96 coupled to 5d, the CP is connected via the second relay substrate 97 provided on the rear surface constituting substrate 50.
It is adapted to be connected to a control board 98 having a control circuit composed of U or the like (see FIG. 10).

This facilitates the handling of the lead wires drawn from the variable display mechanism unit 60 having a large number of electric drive sources and detectors when the variable display mechanism unit is assembled, and
The lead wire of the variable display mechanism section will not be entangled with parts such as the winning ball payout device provided on the back surface of the game board. Further, since each lead wire is put together into a bundle of connecting wires 96 and then connected to the control board 98 via the second relay board 97, the electric power to the control board 98 after the variable display mechanism unit is assembled. Connection work will be very easy.

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 end portions of the lead wires are inserted from the horizontal direction. Therefore, as compared with the case where the plug is inserted at a right angle to the lower wall 61b, the amount of protrusion from the wall surface is small, and the entire variable display mechanism section is compact.

Moreover, the relay board 93 is provided on the lower wall 61 of the variable display mechanism section 60.
Since it is attached to b, a sufficient distance from other parts can be secured, and as a result, the relay board 93
Radiation of Joule heat generated in 1 is sufficiently performed, and local temperature rise can be prevented. That is, since the winning ball storage tank, the winning ball payout device, and the like are arranged in the vicinity of the variable display mechanism section 60 from the upper side to the lateral side, there is not enough space. On the other hand, since the variable winning device is only slightly projected downward, a relatively wide space is secured.

FIG. 10 is a view of the variable display device 4 seen from the rear of the game board. The second relay board 97 is arranged in the upper left corner of the back surface constituent board 50 attached to the back surface of the game board 1.
Here, the 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 illumination means 25 on both sides, the solenoid 56 arranged at the lower part of the rear surface constituting substrate 50, the specific winning detectors 33 and 34, etc. are also connected. Via a relay board 97, each pachinko gaming machine is electrically connected to a control board 98 provided on the back or the like.

Below the back surface constituting substrate 50, the back mechanism part of the variable winning a prize device 5 is arranged so as to penetrate the game board and project backward, and an opening / closing door that covers the winning opening on the front surface of the variable prize winning device 5. The solenoid 56 is arranged above the rear end of the transmission member 5d connected to 5c (see FIG. 2) so that the tip of the plunger of the solenoid 56 faces the transmission member 5d.

[Operation / Effect] In this invention, an armor member having a hitting ball guiding surface is provided on the upper side of an alternating current surface that is substantially flush with the game board, and a recess forming wall projecting rearward is provided inside the alternating current surface. The rear end of the forming wall has a plurality of display window parts corresponding to the respective rotary display members (rotary drums), and a display in which a continuous transparent protective member is joined to the back part of the display window parts. Since the panel is fixedly provided to form the front constituent substrate of the variable display device, the opening area of the display window portion is reduced, and the peripheral edge of the display window portion is reinforced by the recess forming wall, the transparent protective member, etc. The strength of the front component substrate is increased, and the durability of the variable display device is improved.

Further, according to the present invention, since the opening area of the display window is small, a semi-cylindrical shape is provided on the front surface of the main body (variable display mechanism) so as to cover the rotary drum (rotary display member) as in the prior art. Compared to the case where the transparent protective member formed is engaged with the mounting hole provided in the game board from the rear side, the amount of protrusion of the transparent protective member into the game machine area is reduced. Therefore, since the space in front of the transparent protective member through which the game ball can pass is widened, the game balls flowing down the left and right game areas are frequently exchanged with each other, whereby the specific winning opening arranged below the variable display device. This has the effect of increasing the probability of winning a prize in the special winning device.

Further, according to the present invention, since the display window is located deeper than the surface of the game board, it becomes difficult for the hit ball that has flowed down to collide with the display part, that is, the transparent protective member, and the hit ball hits the protective member. It is possible to prevent the display from being damaged by damaging or damaging the transparency and making it difficult to see the display, and at the same time, there is an effect that the reflection of the illumination light from above the game board is reduced and the display becomes clear.
