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 called a 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, identification marks such as numbers, codes, and pictures displayed on a plurality of (for example, four) segment-type displays made of LEDs are used to indicate the winning of a ball hit into a specific winning opening in the gaming area. The so-called so-called jackpot is made to operate variably by a stop switch or a timer, and is stopped by an automatic stop by a stop switch or a timer, and when the combination of numbers in the stopped state reaches a specific preset combination, a specific condition (jackpot condition) occurs. A digital variable display device and several (for example, three) drums with identification marks such as numbers, codes, and pictures attached to the outer periphery are rotated by a stop switch or timer when a prize is won in a specific prize opening. There has been provided a so-called rotary drum type variable display device that is made to stop in sequence and generate a specific mode depending on the combination of numbers and pictures in the stopped state.

[Problem] However, in a rotary drum type variable display device, in order to detect the occurrence of a specific condition, it is necessary to detect the stop position of each drum, so the control device itself that controls the variable display device has to grasp the displayed content. It is difficult to configure a means for detecting the occurrence of multiple types of specific modes compared to digital variable display devices that can be used. For example, using a micro switch 5
In order to detect the occurrence of one type of specific aspect, five detectors are required for each drum, which may increase the size of the entire device.

Therefore, a light emitter and a light receiver are arranged facing each other on both sides of the rotating drum, and a light guiding section is provided on each drum, so that the occurrence of a specific aspect is directed to the detection optical axis of the light guiding section provided on each drum. A possible method is optical detection based on the condition of coincidence. However, even with the detection method using the optical sensor as described above, in order to detect the occurrence of multiple types of specific aspects, multiple sets of emitters and receivers are required, as well as, for example, three sets of light receivers. In a variable display device having rotating drums, when the identification marks on the surfaces of two of the rotating drums are aligned in a predetermined state,
In order to detect this as a second specific mode called a "mid-hit" and give a smaller profit than a "big hit" (for example, by releasing the variable prize winning device only once for a short period of time), the above-mentioned method can be used. This is extremely difficult to achieve with a combination of emitter and receiver. Therefore, there are limits to the types of specific aspects that can provide special benefits.

[Purpose of the invention] The purpose of this invention is to provide a rotating drum type variable display device that indicates when the identification marks such as numbers and patterns on the surfaces of some of the plurality of rotating drums are aligned in a predetermined state. The purpose of the present invention is to make it possible to easily detect the game information and to set a wide variety of specific modes, thereby diversifying the game contents.

[Means for solving the problem] This invention involves arranging a light emitter and a light receiver facing each other on both sides of the rotating display member, corresponding to the light guide provided on each rotating display member (rotating drum). In addition, a detection assisting member such as a magnet is provided on the surface of the cylindrical display portion at the periphery of the rotating display member, and a detection auxiliary member such as a magnet is provided on the surface of the cylindrical display portion at the periphery of the rotating display member. In part, by providing a detector such as a reed switch corresponding to the detection auxiliary member to constitute a second specific mode occurrence detector, it is possible to detect the surface of some of the drums among the plurality of rotating drums. By making it possible to easily detect when the numbers and symbols of the game are arranged in a predetermined state, it is possible to generate a wide variety of special modes, thereby achieving the above-mentioned purpose of diversifying the game content. It is something to do.

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 engage with the guide part 47 at the rear end of the front component board 40 is formed on the standing wall 51 at the periphery of 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 point, 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 mounting 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. Of the two pairs of attachment receiving parts 59, only the one above the opening 50a is shown in the drawing, but an attachment receiving part 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 part 62 having a mounting hole 62a along both side edges, and the ends of the side walls 61c and 61d are brought into contact with this upright part 62. By inserting screws from the sides and screwing them into the mounting holes 62a, the upper wall 61a, lower wall 61b and 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 to the driven gear 65. Further, boss portions (4 pieces) 66 protruding outward are formed on the side wall 61c, and the boss portion 66 is equipped with a driving means 67 consisting of a motor 67a and a first speed change portion 67b that slows down the rotation of the motor 67a. A storage case 68 for holding 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 rotated smoothly. 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 the retaining rings 71b and 71a of the adjacent pair are empty.
C ₁ , each retaining ring 71a, 71b
Frictional force acts only on one side. Therefore, each retaining ring 71a, 71b is prevented from spinning idly. 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 to the outer periphery of the shaft, will 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 in order 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, and between the guide parts 162a and 162b, the solenoid 78 Positioning is automatically performed by engaging the two. In the normal state (demagnetized state) of the solenoid 78, the plagiar 78a is raised by the force of the return spring 78b, which urges the end locking portion 76a of the stopper lever 76 toward the main shaft, causing each rotation to be displayed. It comes into contact with the outer periphery of the ratchet portion 72d of the member 72 to prevent its rotation.

However, when the solenoid 78 is energized, the plunger 78a is lowered and the stopper lever 76
is rotated, and the locking portion 76a at the tip is lifted and 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, a plurality of holes (5 in the drawing) are located on a concentric circle centered on the through hole 63 through which the main shaft 64 is inserted.
A number of light projecting sections 81 are provided respectively. 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. 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 the inside is provided on the side wall 61d.
attached to the outer surface of the

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 identification marks such as numbers, codes, and patterns on the surface of each cylindrical display part 72c are aligned in a predetermined state, the cylindrical display parts are arranged in advance so that the light guide parts 72e inside the main wall 72b coincide with each other. The arrangement of the identification mark on the surface of 72c has been determined. Therefore,
When the identification marks are aligned in a predetermined state and stopped, the light guide portions 72e of each rotary 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 identification marks on the surface of the screen are aligned in a predetermined state (occurrence of a specific condition), and the variable prize winning device 5 is operated for a certain period of time (for example, 30 seconds) or for a predetermined number of pieces (for example, 10 pieces).
To generate a special game state called a "jackpot" in which the game is opened until there is a winning ball, and this is repeated multiple times (for example, 10 times) when a continuation condition (winning in the special winning hole 5c) is met. I can do it.

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 . When the rotating display member 72 stops, the magnet 90
If both are located at the upper end, these two rotational 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 perpendicular 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, a method is adopted in which the stopper lever 76 enters through the gap _C2 to stop the rotation, thereby preventing the stopper lever ₇₆ from falling off. was avoided as follows.

That is, a first unformed cavity E ₁ 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. Furthermore, a second unformed cavity E2 is formed inside the ratchet part 72d, and a cylindrical light receiving part _E2 is formed in the second unformed cavity E2 of the rotary display member ₇₂ on the light receiving part side (leftmost side). A weighted portion _F2 is formed between the tip of the portion 85 and the ratchet portion 72d, and the second unformed empty portion E2 of the second and third rotary display members ₇₂ from the left is provided with the first and third portions. The tip of the light guide section 72e of the second rotating 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.
72a, and a connecting surface 172c that reaches the base of the engagement surface 172a at a gentle inclination angle from the reinforcing surface 172b.
A chevron-shaped claw 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 identification marks 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.

FIG. 11 and FIG. 12 show a second embodiment of the aforementioned middle hit state (second specific mode) occurrence detector.

In this embodiment, two rows of magnets 90 are embedded in the surface of the cylindrical display portion 72c at the periphery of one rotary display member 72, and the upper wall 61a of the frame 60 corresponds to the two rows of magnets 90. On the bottom side of the
Rotary position detector 91 consisting of a set of reed switches
is attached by a mounting board 92.

This makes it possible to detect not only one type but several types of middle hit states.

For example, the magnet 90 is attached to the cylindrical display section 7.
A recess is formed on the surface of the display part 72c, the magnet 90 is fitted into the recess, and a sticker with numbers and designs printed on the surface is pasted on the outer peripheral surface of the display part 72c to prevent it from falling off. It can be buried.

In each of the above embodiments, a combination of a magnet 90 and a reed switch 91 is used as means for detecting the middle hit state, but the detecting means is not limited to this, and the magnet 90 as a detection auxiliary member is Alternatively, instead of using the reed switch that constitutes the rotational position detector 91, a Hall element that is sensitive to the magnetic field of the magnet can be used.
Alternatively, an optical sensor is used as a rotational position detector and a reflection plate is used as a detection auxiliary member for the rotation display member 72.
It may be attached to the outer peripheral surface of the. moreover,
As the middle hit detection means, a proximity switch or other non-contact type detector can be used. As described above, it is preferable to use a non-contact type detector because detection can be performed without affecting the rotation of the rotary display member, but it is also possible to use a contact type detector such as a micro switch.

[Function/Effect] As explained above, this invention has a light emitter and a light receiver facing each other on both sides of the rotating display member, corresponding to the light guide provided on each rotating display member (rotating drum). By arranging the rotating display member, a detection auxiliary member such as a magnet is provided on the surface of the cylindrical display portion at the periphery of the rotating display member. A detector such as a reed switch was provided in a part of the holding frame corresponding to the detection auxiliary member to constitute the second specific mode occurrence detection means, so that a plurality of (three in the example) rotation Not only is it possible to detect the occurrence of the first specific condition in which all the identification marks on the surface of the display member are aligned in a predetermined state, but also it is possible to detect the occurrence of the first specific state in which all the identification marks on the surface of the display member are aligned in a predetermined state. It is now possible to easily detect that the identification marks on the surface are aligned in a predetermined state, and this has the effect of making it possible to generate a rich variety of specific modes, thereby diversifying the game content. .
