Description

  The present invention relates to a center case of a gaming machine such as a pachinko machine.

As a game machine such as a pachinko machine, generally, a movable object mainly using a drive source and a gear is used as a movable member for the purpose of decoration or notification in a variable prize apparatus. These movable objects are very important not only for notifying the progress and state of the game but also for decoration and production, and their structures and mechanisms tend to be complicated at present.
For example, as in Patent Document 1, there is a gaming machine in which a movable body is moved by a driving source via two gears, and the progress and expectation of the game are notified according to the state, thereby increasing the interest of the player. In this document, the movable body is moved to a certain position by the driving source, and thereafter, a weight member is provided in a mechanism such as a seesaw member disposed on the back side of the movable body, and the connection between the driving source and the seesaw member is established. The seesaw member is tilted to the final position by a natural fall due to the weight of the lifting weight member itself.

JP 2003-126420 A

However, in the mechanism of the movable body as described above, it is movable by a drive source through a gear up to a certain position, but for the subsequent movement and tilting of the weight member with respect to the tilting. Since it falls by natural fall, the problem that abrasion of a seesaw member increases by the rapid inclination of a weight member arises. In addition, since a sudden force is applied to the gear, a useless force is applied to the meshing, and the gear may be worn or deteriorated.
Moreover, it is a movable body arrange | positioned in the position which can be visually recognized from a player, and patent document 1 has shown the expectation degree of the game state after a movement with this movable body. In particular, assuming that the state of moving to the final position by natural fall is the notification with the highest expectation, the player pays attention to the movement of the movable body. Therefore, when the structure of the weight member is naturally dropped as described above, the force that tilts to the final position is abrupt, and the gear meshes and moves accordingly.Therefore, there is a great possibility that gear backlash will occur. It is done. In particular, if the weight member tilts suddenly, it is natural that a rebounding force will be generated, and it is possible that the movable body may return from the final position due to the clearance in the gear notch. It becomes impossible to grasp accurately.

  Accordingly, the present invention has been made to solve the above-described problems, and in a center case of a gaming machine having a movable member for decoration or notification purposes, the movable member can be in a desired state with a simple structure. It is an object of the present invention to provide a center case of a gaming machine that can be stably held and operated, and can eliminate problems caused by rapid movement of a movable member and backlash of a gear that drives the movable member.

The center case of the gaming machine according to claim 1 of the present application, an image display device having a display unit,
A screen frame forming a frame having a display opening that can be visually recognized by the display unit;
A decoration object formed by a plurality of objects;
In the center case of the gaming machine, the display unit is visible through the screen frame, and has a decorative frame body having an opening through which the decorative object can be visually recognized.
The decorative object is
A first object attached to the inner periphery of the opening of the decorative frame;
A second object attached to the front surface of the frame of the screen frame,
The second object is:
A base member fixed to the front surface of the frame of the screen frame;
An operating state attached to the base member so as to be rotatable around a rotation axis in the front-rear direction substantially orthogonal to a plane parallel to the display unit, and protruding to the front side of the display unit; A movable member operable to a normal state that does not protrude to the front side of the display unit;
A drive unit for driving the movable member by connecting an output shaft of a motor to the movable member via a gear;
A cover member covering the front side of the movable member in a normal state so as to hold the movable member in a normal state in a concealed state;
A weight member that is disposed at a position that is substantially symmetric with respect to the position of the center of gravity of the movable member around the rotation axis, and is attached to the movable member;
When the movable member is moved to the operating state, the movable member is joined to the lower surface of the first object, and the movable member is configured to complete one decoration object together with the first object.
The direction of the moment of force generated in the movable member due to gravity applied to the weight member is a direction in which the movable member is pushed toward an appropriate position in the normal state in the normal state, and the movable member is in the operational state in the operational state. A center case of a gaming machine, wherein an attachment position of the weight member is set so as to be pushed toward an appropriate position.

For example, as in claim 2, the second object is:
A photosensor attached to the base member for detecting that the movable member is in a normal position;
An attachment portion for attaching the weight member,
A detection piece for position detection by the photosensor may be provided so as to protrude from the mounting portion, and in the normal state, the detection piece may be detected by the photosensor.

According to the center case of the gaming machine according to claim 1, the movable member that is normally hidden in the cover member of the second object protrudes to the front side of the display unit when in the activated state, and the lower surface of the first object. It is possible to perform a highly interesting and highly visible production or decoration or state notification, in which the first object is combined with the first object to form one decoration object.
Moreover, the movable member is driven by connecting the output shaft of the motor to the movable member via a gear (that is, a configuration that does not use the natural fall of the weight member as in Patent Document 1), and the center of gravity of the movable member. In this configuration, the weight member is attached at a position that is substantially symmetrical with the position. As a result, a sudden movement due to a natural fall is eliminated, and the moment of force due to gravity applied to the movable member by the weight member is canceled. For this reason, the trouble that the movable member returns from the final position can be avoided with a simple structure, stable operation of the movable member can be realized, and problems of gear wear and deterioration can be avoided. Further, there is an effect that the load on the motor of the drive unit can be reduced.

  In addition, the malfunction that a movable member returns from the last position (namely, proper position), and the solution are demonstrated concretely below. In the center case of the gaming machine, when the movable member that is normally hidden in the cover member of the second object is in the activated state, the front side of the display unit is rotated by the rotational movement about the rotation axis in the front-rear direction. And appear to be joined to the lower surface of the first object. For this reason, when there is no weight member, the direction of the moment of force generated by the gravity applied to the movable member (moment about the rotation axis, the same applies hereinafter) is the normal state in which the movable member is operated from the proper position in the normal state. In the operating state, the movable member is pushed downward from the proper position in the operating state toward the normal position. Therefore, if there is no weight member, even if the motor is controlled to bring the movable member into the operating state, the movable member hangs down at least as much as the backlash of the gear of the drive unit, and the first object and A considerable gap is generated between them. Further, even if the motor is controlled so that the movable member is in a normal state, the movable member moves from an appropriate position in the normal state (a position where it is completely hidden in the cover member) by the amount of the backlash. There is also a risk of a slight overhang.

However, in this gaming machine, the weight member is attached to the movable member at a position that is substantially symmetrical with the center of gravity about the rotation axis. Moreover, the direction of the moment of force generated in the movable member due to the gravity applied to the weight member is normally the direction in which the movable member is pushed toward the proper position in the normal state, and in the activated state, the movable member is in the proper position in the activated state (the first position). The attachment position of the weight member is set so as to be pushed toward one object) or a position where the object is pressed with a slight gap. For this reason, the aforementioned moment of force due to the dead weight of the movable member is canceled, and the above-mentioned problems are prevented. For example, if the weight member is sufficiently heavy, the direction of the moment of force due to gravity applied to the movable member (entirely including the weight member and the like) in the operating state is pressed against the lower surface of the first object by pushing the movable member upward. It becomes the direction. For this reason, even if there is a considerable amount of backlash in the gear of the drive unit, there is a problem that a large gap that makes the movable member hang down from the appropriate position in the operating state and makes the first object look bad is created. To be avoided. For the same reason, it is possible to prevent a problem that the movable member normally protrudes toward the display unit.
In a normal state, it is possible to produce a more impressive and effective performance by ensuring that the movable member is concealed until the movable member appears.
In addition, when there is no gap between the movable member and the first object in the operating state, it is possible to avoid a problem that the illumination light for production from the rear inadvertently leaks to the front side.

  In addition, according to the center case of the gaming machine of the second aspect, the normal state can be reliably detected by the photo sensor. In addition, since the detection piece for position detection protrudes from the attachment portion of the weight member, the attachment portion of the weight member can be used as a detection piece installation space, and the structure can be simplified.

Hereinafter, as an embodiment of the present invention, a configuration example when applied to a pachinko machine will be described with reference to the drawings.
A. FIG. 1 is a front view showing a game board of a pachinko machine according to the present embodiment. In FIG. 1, reference numeral 1 denotes a game board, and a game area 3 is formed by surrounding a substantially circular area on the front surface with a guide rail 2.

Further, a decorative portion 22 is provided on the left side of the center case 10, and a warp port 23 for guiding the game ball into the center case 10 is provided in the decorative portion 22. For example, a game ball that has flowed down to the left after flowing down on the center case 10 hits the obstacle nail (not shown) and flows into the warp port 23 with a certain probability. In addition, the game ball that has flowed in this way is configured to flow down from the warp port 23 to the stage 21.

  In addition, a start winning induction port 24 is formed at the center of the lower end side of the center case 10 (above the start winning ports 11 and 12). A part of the game ball flowing down to the stage 21 is discharged from the left end portion 24a or the right end portion 24b of the start winning guide opening 24 and guided to the starting winning opening 11 or 12 (that is, high probability). In the start winning opening 11 or 12). Note that the game ball that has flowed down to the stage 21 and discharged from the central portion 24c of the start winning guide port 24 has a low probability of winning the start winning port 11 or 12.

  Further, a decorative portion 25 is provided at the lower right side of the center case 10, a decorative portion 26 is provided at the upper right side of the center case 10, a decorative portion 27 is provided at the upper side of the center case 10, and a decorative portion 26 is provided on the back side of the decorative portion 26.

Here, the decoration part 27 corresponds to the first object of the present invention, and the decoration part 28 corresponds to the second object of the present invention.

  Next, the display device body 5 has a display unit 6 (screen) capable of displaying identification information (sometimes referred to as a special figure) such as numbers and characters (for example, a liquid crystal display device). Can be displayed. For example, special charts are displayed in three vertical columns on the left, center, and right, and special figures consisting of numbers, letters, etc. in each column are displayed in a stopped state (stop display), or in a fluctuating state (for example, vertically) Display in a scrolling state) (that is, a variable display). In addition to the special figure, the display unit 6 can display an image for production such as a background image or a character image or an information notification image. In the case of this example, the special figure displayed on the display unit 6 of the display device body 5 is a production dummy, and the special figure that is not a dummy (this special figure) is the special figure 1 display 15 or the special figure 2. Displayed on the display 16.

The variable winning device 13 is a device having a big winning opening 13a that is opened on condition that a big hit described later is reached.
The start winning ports 11 and 12 are winning ports that each function as a start winning port of a separate special drawing. Among these, the start winning port 11 is disposed directly below the left end 24 a of the start winning guide port 24, and the start winning port 12 is disposed directly below the right end 24 b of the start winning guide port 24. In this specification, the special view of the variable display game executed based on the winning to the start winning opening 11 is referred to as a special figure 1, and the special view of the variable display game executed based on the winning to the start winning opening 12 is shown. Is special figure 2.

Next, the special figure 1 display 15 is a 7-segment display capable of displaying numbers and the like as the special figure, and the fluctuation of the special figure is based on the start memory generated by winning the start winning opening 11. This is for executing the display. The special figure 2 display 16 is a display similar to the special figure 1 display 15 for executing the variable display of this special figure based on the start memory generated by winning the start winning opening 12. Is.
Further, the special figure 1 memory display 17 is composed of small lamps provided at four locations around the special figure 1 display 15, and the start memory generated by winning the start winning opening 11 is determined by the number of lighting of the lamps. The number (in this case, the upper limit number is 4) is displayed. Similarly, the special figure 2 memory display 18 is composed of small lamps provided at four locations around the special figure 2 display 16, and the start generated by winning at the start winning opening 12 depending on the number of lighting of the lamps. The number of memories (in this case, the upper limit number is 4) is displayed.
The gaming state 1 indicator 19 is composed of two small lamps provided next to the special figure 1 storage indicator 17 and notifies the gaming state related to the special figure 1 by its lighting state. Similarly, the gaming state 2 indicator 20 is composed of two small lamps provided next to the special figure 2 storage indicator 18, and notifies the gaming state related to the special figure 2 by its lighting state.

B. Configuration of Center Case Next, the configuration of the center case 10 will be described with reference to FIGS. 2A and 2B are diagrams showing the center case, in which FIG. 2A is a front view, and FIG. 2B is a perspective view seen obliquely from the side. FIG. 3 is an exploded perspective view showing the center case 10 and the display device body 5.

The center case 10 includes a decorative frame body 31 attached from the front side of the game board 1 and a screen frame 32 attached from the back side of the game board 1. Note that only a member attached to the front side of the game board 1 (in this case, the decorative frame 31 or the like) may be referred to as a center case, but in this specification, the center case including the decorative frame and the screen frame I'm calling.
A board (so-called veneer) constituting the gaming board 1 is formed with a center case opening (not shown) for fitting the decorative frame body 31, and the decorative frame body 31 is formed from the front surface of the gaming board 1 to the center. Fits into the case opening.

Further, the decorative frame body 31 has a frame shape whose inside is opened forward and backward, and the display unit 6 of the display device body 5 can be viewed from the front through a display opening 33 described later of the screen frame 32. Moreover, the above-mentioned decoration part 22 and the decoration parts 25-27 are provided by fixing the member which respectively comprises these decoration parts to the decoration frame 31 as shown in FIG. The decorative portion 27 (first object) is attached to the inner peripheral edge of the opening of the decorative frame 31 from the back side. The decoration portion 28 (second object) is attached to the front surface of the screen frame 32.
In addition, the decorative frame body 31 is provided with an armor portion 34 protruding forward from above the display portion 6. The armor portion 34 is a portion that prevents the game ball from falling on the front surface of the display portion 6, and guides the game ball that has been driven to the left side of the center case 10 in this example.
On the other hand, the screen frame 32 is a member to which the display device body 5 is attached from the back side, has a rectangular display opening 33 facing the display unit 6 inside, and has a decorative frame body from the back side of the game board 1. This is a member fixed to 31. As shown in FIG. 3, the stage 21 is provided by fixing a member constituting the stage 21 to the lower end portion of the screen frame 32.

C. Configuration of Second Object Next, the configuration of the decoration unit 28 (second object) will be described with reference to FIGS. FIG. 4 is an exploded perspective view of the second object (viewed obliquely from the front side). FIG. 5 is an exploded perspective view of the second object (viewed obliquely from the back side). FIG. 6 is a back view for explaining the operation of the second object (a view in which a base member 39 and a motor 45 described later are removed), FIG. 6 (a) shows a normal state, and FIG. 6 (b) shows an operating state. Show. FIG. 7 is a back side perspective view for explaining the operation of the second object (a view in which a base member 39 and a cover member 40 described later are removed), and FIG. 7A is a view showing a normal state (including a motor 45). 7 (b) shows the operating state (including the motor 45), FIG. 7 (c) shows the normal state (with the motor 45 removed), and FIG. 7 (d) shows the operating state. It is a figure (the figure which removed the motor 45). FIG. 8 is a partially enlarged perspective view of the second object.

As shown in FIGS. 4 and 5, the decoration portion 28 includes a base member 39, a cover member 40, a movable member 41, weight members 42 a, 42 b, 42 c, and a drive portion 44.
Here, the base member 39 is a member fixed to the front surface of the frame body of the screen frame 32 (in this case, the upper right side and the upper right side of the screen frame 32), and has an L-shaped inner edge 39a. The positions of the inner edge 39a in the attached state in the vertical direction and the horizontal direction correspond to the upper side and the right side of the display opening 33 of the screen frame 32. As shown in FIG. 4, in a predetermined position on the front surface of the base member 39 (in the vicinity of the corner of the inner edge 39a, that is, in the vicinity of the upper right corner of the display opening 33), a front and rear bearing hole 39b is provided. Is formed. The bearing hole 39b is inserted so that a rotating shaft 41a described later can rotate. In this case, the bearing hole 39b is provided at the upper left corner of the inner edge 39a as shown in FIG. In addition, a motor mounting portion 39c that opens in the front-rear direction is formed at a predetermined position of the base member 39 (to the right of the corner of the inner edge 39a). Further, a sensor board mounting portion 39d for fixing a sensor board 49 described later is formed at a predetermined position on the front surface of the base member 39 (to the left of the bearing hole 39b).

  Next, the cover member 40 is a member that is fixed to the front side of the base member 39 so as to cover the movable member 41 that is in a normal state, and the movable member 41 that is in a normal state is not visible to the player by the cover member 40. Concealed. Further, a bearing hole 40b in the front-rear direction shown in FIG. 5 is formed at a predetermined position on the back surface of the cover member 40 (position coaxial with the bearing hole 39b).

Next, the movable member 41 is attached to the base member 39 so as to be rotatable around a rotation axis 41a in the front-rear direction substantially orthogonal to a plane parallel to the display unit 6, and It is operable in an operating state protruding to the front side and a normal state not protruding to the front side of the display unit 6. In this case, the rotating shaft 41a is formed integrally with the movable member 41 so as to protrude forward and backward from both the front surface and the back surface of the movable member 41. The rotating shaft 41a has a front end inserted into the bearing hole 40b so as to be able to rotate, and a rear end inserted into the bearing hole 39b so as to be able to rotate. Accordingly, the movable member 41 is supported so as to be rotatable about the rotation shaft 41 a with respect to the base member 39 and the cover member 40.
Then, in the above-described operating state (shown in FIG. 2A, FIG. 6B, etc.), the movable member 41 protrudes to the upper front of the display unit 6 and is joined to the lower surface of the decorative unit 27. At the same time, one decoration object (in this case, the face of the robot) is completed. Further, the movable member 41 is retracted from the front of the display unit 6 and hidden behind the decorative unit 26 and the cover member 40 in the above-described normal state (shown in FIG. 1, FIG. 2B, and FIG. 6A).

  Note that the center of gravity of the movable member 41 (including a driven gear 47 and the like to be described later) when the weight members 42a, 42b, and 42c are not present is in the vicinity of the position indicated by symbol G in FIG. For this reason, when viewed from the front, the direction of the moment of force generated by gravity applied to the movable member 41 is the clockwise direction in the normal state (the direction in which the movable member 41 is pushed to the left from the normal state toward the operating state). In the operating state, the direction is counterclockwise (the direction in which the movable member 41 is pushed downward from the operating state toward the normal position). Therefore, if the weight members 42a, 42b, and 42c are not provided, even if the motor 45 is controlled to bring the movable member 41 into the operating state, at least between the gears described later (between the drive gear 46 and the driven gear 47). The movable member 41 hangs downward by the amount of backlash, and a considerable gap is generated between the decorative portion 27. Further, even if the motor 45 is controlled so that the movable member 41 is in the normal state, the movable member 41 moves to the left by the amount of the backlash, and there is a risk of a problem that the movable member 41 slightly protrudes in front of the display unit 6. There is also.

  Therefore, in this gaming machine, a plurality of weight members 42a, 42b, and 42c are attached to the movable member 41 at positions that are substantially symmetrical with the center of gravity G about the rotation shaft 41a. Moreover, the direction of the moment of force generated in the movable member 41 due to the gravity applied to the weight members 42a, 42b, and 42c is normally the direction in which the movable member 41 is pushed toward the proper position in the normal state (in this case, the direction opposite to that seen from the front). Direction (clockwise direction), and in the operating state, the movable member 41 is pushed toward an appropriate position in the operating state (a position where the movable member 41 is completely in close contact with the decorative portion 27 which is the first object or joined with a slight gap) (this In this case, the attachment positions of the weight members 42a, 42b, and 42c are set so as to be in the clockwise direction when viewed from the front. For this reason, the moment of the force described above due to the dead weight of the movable member 41 is canceled, and the above-described problems are prevented. For example, if the weight members 42a, 42b, and 42c are sufficiently heavy, the moment of force due to gravity applied to the movable member 41 (including the driven gear 47 and the like, and the weight members 42a, 42b, and 42c as a whole) in the operating state. The direction is a clockwise direction when viewed from the front, and is a direction in which the movable member 41 is pressed upward and pressed against the lower surface of the decorative portion 27. For this reason, even if there is considerable backlash between the gears described later, the movable member 41 hangs down from an appropriate position in the operating state, and a large gap is formed between the decorative portion 27 and the appearance is deteriorated. Bugs are avoided. For the same reason, the problem that the movable member 41 protrudes toward the display unit 6 in the normal state is also prevented.

In order to make the weight members 42a, 42b, 42c and their arrangement space compact, the base member 39, the cover member 40, and the movable member 41 are made of, for example, plastic with a low specific gravity, whereas the weight members 42a, 42b. , 42c should be made of a material that has a high specific gravity and is sufficiently heavy. The weight members 42a, 42b, and 42c in this example are columnar members made of metal such as steel, for example. As shown in FIG. 4 and the like, the weight members 42a and 42b are relatively short, and the weight member 42c is The dimensions are relatively long.
In the movable member 41, a plate-like portion 41e is formed at a position that is substantially symmetric with the center of gravity G about the rotation shaft 41a, and weight members 42a and 42b are formed on the back surface of the plate-like portion 41e. , 42c are formed in the recesses 41b, 41c, 41d.
Here, the weight member 42a is fitted into the recess 41b, the weight member 42c is fitted into the recess 41c, and the weight member 42b is fitted into the recess 41d, whereby the weight members 42a, 42b and 42c are attached to the movable member 41. It is done.
Further, a gear base 48, which will be described later, is attached to the back surface of the plate-like portion 41e so that the weight members 42a, 42b, 42c are prevented from falling off (details will be described later).

Next, the drive unit 44 will be described.
As shown in FIG. 5 and the like, the drive unit 44 includes a motor 45, a drive gear 46, a driven gear 47, a gear base 48, and a sensor substrate 49.
The motor 45 has a rear portion fitted into the motor mounting portion 39c of the base member 39 and is fixed to the base member 39. A drive gear 46 is fixed to an output shaft protruding forward from the front surface of the motor 45. Yes.

The gear base 48 has a substantially fan-like plate-like portion 48a fixed to the movable member 41 in a state of being joined to the back surface of the plate-like portion 41e of the movable member 41, and the position of the center of the fan of the plate-like portion 48a. Has a through hole 48b through which the rotary shaft 41a passes.
In addition, the said plate-shaped part 48a has a function which prevents dropping of each weight member 42a, 42b, 42c by joining to the back surface of the plate-shaped part 41e of the movable member 41 mentioned above. A concave portion 48c into which the rear side of the weight member 42c is fitted is formed at a position corresponding to the weight member 42c of the plate-like portion 48a. In addition, the concave portions 41b, 41c, 41d and the concave portion 48c described above constitute an attachment portion for attaching the weight member.
Further, as shown in FIG. 5 and the like, a detection piece 48d protrudes from the back side of the recess 48c.

The driven gear 47 is an arc-shaped member that is arranged around the through hole 48b (that is, the rotation shaft 41a) and is fixed to the back surface of the gear base 48, and teeth that mesh with the teeth of the drive gear 46 are provided on the outer periphery of this member. Formed.
In this case, the rotation of the output shaft of the motor 45 is decelerated and transmitted to the gear base 48 (and hence the movable member 41 to which the gear base 48 is fixed) by the driven gear 47 and the drive gear 46 meshing and rotating. Then, the movable member 41 is driven.

The sensor substrate 49 is a substrate on which a photosensor 50 that detects the initial position of the movable member 41 is mounted on one surface, and the sensor of the base member 39 described above is in a posture with the surface on which the photosensor 50 is mounted facing the front surface. It is fixed to the board mounting part 39d. The photosensor 50 includes a light-emitting element and a light-receiving element that face each other, and the output of the light-receiving element changes when the detection piece 48d blocks light transmitted and received between these elements, and the sensor output is turned on based on this change. It becomes a state (detection state).
In this example, when the movable member 41 is in the normal state, the detection piece 48d comes to a position (shown in FIG. 8) where the light of the photosensor 50 is blocked, and the photosensor 50 is turned on. That is, the initial position detected by the photosensor 50 is the position of the movable member 41 in the normal state.

D. Outline of Game Next, an outline of a game performed in the pachinko machine of the present embodiment and a flow of the game will be described.
First, at the beginning of the game (or before the start of the game), the customer is in a waiting state (during demonstration), and the customer waiting image (video or still image) is displayed on the screen (display unit 6) of the display device 5. ) Is displayed.
When a game ball that has been thrown into the game area 3 through the guide rail 2 wins the start winning opening 11 or 12 (that is, when there is a start winning of a special figure), a special figure (dummy) is displayed on the display unit 6. While the fluctuation display is performed, the fluctuation display of the special figure is performed on the corresponding display of the special figure (the special figure 1 display 15 or the special figure 2 display 16), and the fluctuation display game is executed.
In the case where both of the special memories of FIG. 1 and FIG. 2 exist, for example, the variable display game of FIG. 1 and FIG. 2 may be executed alternately. The display area may be formed separately, and the variable display of each special figure on the display unit 6 may be executed independently, and the variable display game of the special figures 1 and 2 may be executed independently. Moreover, the aspect by which the fluctuation | variation display game of a special figure 1 or a special figure 2 is performed in order with a start winning prize may be sufficient.

And, apparently, the special display stop display mode (a combination of special maps derived by the variable display) in the display unit 6 of this variable display game is a special display mode (for example, “3, 3, 3”, etc.) ), A bonus called jackpot is given to the player. In terms of control, for example, on the condition that there has been a start winning, the value of the big hit random number is extracted and stored, and the random number value that has been extracted and stored is compared and determined at the time of determination. Based on the determination result, whether or not to make a big hit is determined in advance, and the variable display game is started in response to this determination. In addition, if the stop display mode of the variable display game is a specific mode (for example, “7, 7, 7”, etc.), it will be a big hit and after a big hit game (after an opening operation to be described later) It becomes a state (probability fluctuation state) in which control for increasing the probability of winning a big hit is performed.
In addition, before the end of the above-mentioned variation display game, a special effect called reach action (for example, an operation in which two columns of special drawings are made the same pattern and the remaining one column is slowly changed) is displayed on the display unit. 6 is executed.

  When the big hit state is reached, an opening operation is performed in which the big prize opening 13a of the variable prize winning device 13 is temporarily opened for a period up to, for example, ten prizes within a range not exceeding a prescribed time (for example, 30 seconds). Is called. This release operation is performed up to 15 rounds, for example. In this jackpot state, display of the jackpot image for producing the jackpot state or notifying the player of the number of jackpot rounds is executed on the display unit 6.

Further, when a game ball is further won in the start winning opening 11 or 12 during the above-described variation display game or big hit, the special figure memory display 17 or the special figure 2 memory display 18 is used in this case. After the start memory display is performed, up to four are stored, and after the variable display game or jackpot ends, the variable display game of the above-mentioned special figure is repeated based on the memory (that is, the start memory), or a waiting state is entered. Go back.
That is, if any of the special display variation display games ends with a big win, the game shifts to a big hit state. The corresponding variable display game is executed, and if any of the variable display games is finished out of play and there is no start memory, it returns to the customer waiting state, and if the big hit ends and there is a start memory of any special figure, it starts again The variable display game corresponding to the memory is executed, the jackpot is completed, and if there is no start memory for any special figure, the flow returns to the customer waiting state.

  In the game flow as described above, in which state the operation of the movable member 41 of the decorative portion 28 described above (the operation from the normal state to the active state) is not particularly limited. For example, in order to produce a state in which the special figure is a big hit, an operation to activate the movable member 41 may be performed after the special figure is a big hit. The operation of the movable member 41 described above may be executed before the big hit of the special figure. Alternatively, for example, in order to produce a probability variation state, the operation of the movable member 41 described above may be executed after the transition to the probability variation state, or to predict the possibility of transition to the probability variation state, the probability variation The operation of the movable member 41 described above may be executed before the transition to the state. Alternatively, the above-described operation of the movable member 41 may be executed in order to notify any state (particularly difficult to recognize) during the progress of the game.

  According to the gaming machine of this example described above, the movable member 41 that is normally hidden in the decorative portion 28 (inside the cover member 40) on the right side of the center case 10 blocks the front of the display portion 6 in the activated state. In this way, it is a highly interesting and highly visible production or decoration or state that is joined to the lower surface of the decorative part 27 provided on the upper side part and is combined with the decorative part 27 to constitute one decorative object. Notification can be performed.

  In addition, the movable member 41 is connected to the output shaft of the motor 45 via the gears 46 and 47 to drive the movable member 41 (that is, a configuration that does not use the natural fall of the weight member as in Patent Document 1). In addition, the weight members 42a, 42b, and 42c are attached at positions that are substantially symmetrical with the center of gravity of the movable member 41. As a result, a sudden movement due to a natural drop is eliminated, and the moment of force due to gravity applied to the movable member 41 by the weight members 42a, 42b, 42c is canceled. For this reason, the trouble that the movable member 41 returns from the proper position is avoided with a simple structure, and stable operation of the movable member 41 can be realized, and problems of wear and deterioration of the gears 46 and 47 are also avoided. In addition, there is an effect that the load on the motor 45 of the drive unit 44 can be reduced.

In a normal state, it is possible to produce a more impressive and effective performance by ensuring that the movable member 41 is kept hidden until the movable member 41 appears.
In addition, when there is no gap between the movable member 41 and the decorative portion 27 in the operating state, it is possible to avoid a problem that the illumination light for production from the rear inadvertently leaks to the front side.
Further, according to this gaming machine, normal state detection can be reliably performed by the photosensor 50. Further, since the detection piece 48d for position detection protrudes from the attachment portion of the weight members 42a, 42b, 42c, the attachment portion of the weight members 42a, 42b, 42c can be used as a detection piece installation space, and the structure is simple. Can be achieved.

The present invention is not limited to the above-described embodiments, and various modifications and applications are possible.
For example, in the above embodiment, the example in which the movable member 41 appears from the right side is shown. However, the movable member 41 may be hidden from the left side in the normal state and appear from the left side in the operating state. Moreover, the weight member may be one.

  In addition, it should be considered that the embodiment disclosed this time is illustrative and not restrictive in all respects. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
