FIGS. 5A and 5B are a front view of a main part showing a closed state of the decorative body unit, and a side view of the drive mechanism in the closed state, and FIG. 6 is a perspective view of the drive mechanism in the open state. 7 is an exploded perspective view of the drive mechanism, FIG. 8 is an exploded perspective view of the main part of the drive mechanism, and FIGS. 9A and 9B are explanatory views of the configuration of the gear mechanism that opens and closes the opening / closing member. .
The movable decorative body unit (decorative body unit) 30 is arranged on the board surface of the game board 3 and drives the movable decorative body 31 and the movable decorative body (decorative body) 31 that is shaped like a trefoil emblem on the front. And a drive source (not shown).
The decorative body unit 30 does not have to be movable on the game board, and may be a decorative body unit whose position is fixed.
The movable decorative body 31 is supported by the game board 3 (including other members fixed to the game board 3) in a movable state in which the movable decoration body 31 can move forward and backward through a predetermined path. Specifically, the movable decorative body 31 is configured to be movable back and forth between a retracted position above the symbol display device 7 and a protruding position that appears on the front surface of the symbol display device 7. That is, the movable decorative body 31 is configured to be movable back and forth between a retracted position that does not interfere with the display surface of the symbol display device 7 disposed on the game board surface and a protruding position that hides at least a part of the display surface. . In the relationship with the movable accessory 20 shown in FIG. 2, the movable decorative body unit 30 has the movable members 21 and 22 moved to the fully opened state shown in FIG. At this stage, it can be lowered to the front of the symbol display device. Similarly, when the movable members 21 and 22 are fully opened, they are raised from the front of the symbol display device and return to the original position.
In this example, the movable decorative body 31 is visible to the player when in the retracted position, but may be in a concealed position that is not visible to the player when in the retracted position.
The movable decorative body (decorative body) 31 includes a main movable member (main member) 32 configured to be movable forward and backward in the vertical direction on the game board surface, and a plurality of sets provided with the main movable member 32 at different positions in the front-rear direction. Actuated by a driving force from a driving source such as a motor and the first and second opening / closing members 40A and 40B that are pivotally supported by the first and second 33A and 33B so as to protrude and retract in the inner and outer diameter directions, respectively. And a drive mechanism 55 that moves the open / close members 40A and 40B together.
When the decorative body 31 is fixed in position, the main member 32 is also fixed in position.

One of the characteristic configurations of the present invention is that the change in the shape of the movable decorative body 31 has a three-dimensional effect and diversity by opening and closing the opening and closing members having different positions in the front-rear direction.
The first opening / closing member (group) 40A and the second opening / closing member (group) 40B, which are arranged at different positions in the front-rear direction, can be freely opened and closed by the first and second shaft support portions (group) 33A, 33B, respectively. Each opening / closing member 40A, 40B is pivotally supported and retracted to the inner diameter side when viewed from the front when in the closed position, while projecting to the outer diameter side of the outer periphery of the main movable member when in the open position. It becomes a state.
The main movable member (main member) 32 includes a disk-shaped decorative plate 34 positioned on the front surface, and a substantially cylindrical casing (not shown) that is fixed to the rear surface of the decorative plate 34 and supports the drive mechanism 55. . The outer peripheral edge of the decorative plate 34 is formed as an extended portion 34a that protrudes in the outer diameter direction from the outer peripheral surface of the casing, and the opening and closing members 40A and 40B in the closed position are accommodated on the back surface of the extended portion 34a of the decorative plate 34 At least a part is concealed. In this example, when each open / close member 40A, 40B is in the open position, it is in a state of projecting in a petal shape on the outer diameter side of the outer periphery of the main movable member.
Accordingly, each of the opening / closing members 40A and 40B is at least partially hidden when viewed from the front when in the closed position retracted to the inner diameter side as shown in FIG. 3A, while as shown in FIG. When it is in the open position that is expanded approximately 90 degrees toward the outer diameter side and is substantially parallel to the game board surface, the outer peripheral edge of the main movable member 32 is in a visible state protruding toward the outer diameter side. That is, each of the opening / closing members 40A and 40B is concealed by the outer peripheral edge of the main movable member 32 when in the closed position and at least a part of the opening / closing members 40A and 40B is not visible from the front. It will be in the state protruded in the shape of a petal on the outer diameter side. The projecting angle of the opening / closing member at the time of opening may be parallel to the game board surface, or may be an angle inclined with respect to the game board surface.

For this reason, when each of the opening / closing members 40A and 40B is opened, it is possible to produce an unexpected effect such that the area of the main movable member 32 is suddenly expanded or the shape is suddenly changed. In particular, by providing a pattern that is related to a pattern drawn on the front surface of the main movable member 32 or a pattern that is not related to the front surface of each opening / closing member 40A, 40B, the pattern is opened by opening the opening / closing member. (Crest) Enlarge the shape of the whole or change the overall image of the pattern.
In particular, in the present invention, since the front and rear position of the first and second opening / closing members are different, a three-dimensional effect can be imparted to the deformation mode and a variety of changes can be produced.
Each of the opening / closing members 40A, 40B constituting the movable decorative body 31 has characters and designs drawn on the front surface of a small-sized circular plate-like body, and when the opening / closing members 40A, 40B are shifted to the open state. Since the decoration is added along the outer peripheral edge of the emblem drawn on the front surface of the main movable member 32, the area of the emblem increases and the shape changes to a different shape. Since the movable decorative body 31 is enlarged and deformed after a simple operation of moving along the game board surface, the player can enjoy a variety of effects.

Further, if all or part of the opening / closing members 40A and 40B are made of a transparent or translucent light-transmitting material, or if a part is provided with a penetrating part, the movable decorative body 31 is placed on the front surface of the symbol display device 7. By opening the opening / closing member when the door is stopped, the illumination effect of causing the opening / closing member to emit light by the emitted light from the symbol display device 7 can be exhibited.
In addition, by making the patterns, characters, and the like displayed on the screen of the symbol display device 7 cooperate with the shape of the opening / closing member and the drawn pattern, it is possible to exhibit a variety of effects.
The drive mechanism 55 according to this example includes a first drive unit 55A that drives a first opening / closing member (group) 40A that is pivotably supported by a first shaft support portion (group) 33A, and a second shaft. And a second drive unit 55B that opens and closes a second opening / closing member (group) 40B that is pivotally supported by the support (group) B.
The first drive unit 55A and the second drive unit 55B have substantially the same configuration, and the opening / closing member groups 40A and 40B are moved together by moving the opening / closing lever 55L shown in FIG. 10 in the circumferential direction. Then, it operates between a closed position (FIG. 5) retracted to the inner diameter side and an open position (FIG. 3) protruding to the outer diameter side. The open / close lever 55L is reciprocated by a motor or solenoid (not shown).

The first and second drive units 55 </ b> A and 55 </ b> B are arranged coaxially along the central portion of the main movable member 32 and are supported by a shaft member 56 rotatably supported by the main movable member. Large-diameter gears 57A and 57B with fixed central portions are respectively rotatably supported by support members 61A and 61B and meshed with gear portions partially provided on the outer circumferences of the large-diameter gears 57A and 57B. There are small-diameter gears 58A and 58B that are rotationally driven, and link pieces 60A and 60B that rotate integrally with the small-diameter gears 58A and 58B, and each opening and closing member 40A is provided at the end of each of the link pieces 60A and 60B. , 40B are supported. In addition, when employ | adopting the structure which rotates at least 1 set of opening-and-closing member so that it may mention later, about the said opening-and-closing member, it is rotatably supported by the edge part of a link piece.
Accordingly, by rotating the large-diameter gears 57A and 57B in both forward and reverse directions, the small-diameter gears 58A and 58B are rotated in both forward and reverse directions. As a result, the link pieces 60A integrated with the small-diameter gears, 60B rotates (FIG. 9).

When the drive mechanism 55 is assembled, as shown in FIG. 7, in this example, the shaft member 56 protruding from the center of the second drive unit 55B protrudes from the center of the lower surface of the first drive unit 55A. The drive shafts 55A and 55B are assembled by fitting the shafts.
Since the first opening / closing member 40A and the second opening / closing member 40B are displaced in the circumferential direction, the second opening / closing member 40B can be visually recognized from the gap between the first opening / closing members 40A when opened.
Each of the large diameter gears 57A and 57B may have a gear portion only in a portion corresponding to each of the small diameter gears 58A and 58B as shown in detail in FIG. 7, FIG. 8, and FIG. And may have a gear portion. By shifting the circumferential position of the outer peripheral gear portion of each large-diameter gear 57A, 57B or by varying the circumferential length, a timing shift is imparted to the operation of each opening / closing member that opens and closes by the rotation of the shaft member 56. Thus, the opening / closing operation may be varied.
9A, when the large-diameter gear 57A rotates in the direction of arrow M, the opening / closing member 40A rotates in the counterclockwise direction (closing direction) together with the small-diameter gear 58A, and is indicated by a solid line in FIG. 9B. Move to the closed position. On the other hand, when the large-diameter gear 57A rotates in the direction of arrow N, the opening / closing member 40A rotates in the clockwise direction (opening direction) together with the small-diameter gear 58A and moves to the open position indicated by the solid line in FIG. . Reference numeral 65 denotes a stopper that abuts the link piece 60 </ b> A to restrict the open position.

Next, FIGS. 10A and 10B are rear views of the drive mechanism 55, FIG. 11 is a front view showing the configuration of the third drive unit, and FIGS. 12A and 12B are second views. It is operation | movement explanatory drawing of a drive unit and a 3rd drive unit. When the opening / closing lever 55L, one end of which is fixed to the shaft member 56, is in the position shown in FIG. 10A, all the opening / closing members 40A and 40B are closed, while the opening / closing lever 55L is in the position shown in FIG. 10B. When all the opening / closing members 40A and 40B are open, the opening and closing members 40A and 40B are open. The open / close lever 55L is driven to open and close by a motor or a solenoid (not shown).
Further, the drive mechanism 55 includes a third drive unit 55C (opening / closing member rotation mechanism) for rotating the second opening / closing member 40B (first 40A). The third drive unit 55C is coaxial with the shaft member 56 and coaxially with the small-diameter gears 58B on the lower surface of the support member 61B and a large-diameter gear (other large-diameter gear) 70 that is disposed so as to be relatively rotatable. A small-diameter gear (another small-diameter gear) 71 that is arranged and meshes with the large-diameter gear 70. When each small-diameter gear 71 is rotated by rotating the large-diameter gear 70, a small-diameter integral with the small-diameter gear 71 is provided. The gear 58B rotates. On the other hand, a pulley 72 is coaxially integrated with the front surface of each small-diameter gear 58B, and a pulley 73 is integrated with a lower portion of the second opening / closing member 40B. Since a belt (transmission member) 74 is stretched around the outer periphery of both pulleys (transmission members) 72, 73, when the small-diameter gear 71 rotates, the pulley 72 rotates integrally, and the pulley 73 rotates via the belt 74. Let For this reason, the second opening / closing member 40B integral with the pulley 73 can rotate.

In order to rotationally drive the large-diameter gear 70, for example, an operation lever 70a protruding from the back surface of the large-diameter gear 70 may be moved in the circumferential direction by a motor or a solenoid.
3 and 4, the third drive unit 55C is provided on the back-side support member 61B to rotate only the back-side second opening / closing member 40B, but the front-side support member 61A is shown. Alternatively, a third drive unit 55C having a similar configuration may be provided to rotate the first opening / closing member 40A.
In the above embodiment, the opening and closing members 40A and 40B are configured to open and close by transmitting driving force to the link pieces 60A and 60B using gears. However, the opening and closing members are normally closed by a spring or the like. While urging to the position, the link piece and the opening / closing member may be protruded in the outer diameter direction against the spring by the centrifugal force when the shaft member 56 is rotated.

Moreover, in the said embodiment, although it was set as the structure which makes an opening-and-closing member project from the outer periphery of the disk-shaped main movable member 32 which drew the emblem, this invention is taken from the outer periphery of the main movable member which modeled trunks, such as an animal, for example. It can be developed into various variations such as the appearance of the leg. Moreover, you may comprise so that LED may be mounted in an opening-and-closing member and the electrical decoration effect may be exhibited.
In addition, on the front surface of each opening / closing member 40A, 40B in each of the above embodiments, a specific effect is exhibited by drawing a symbol or / and a character matching the symbol drawn on the front surface of the main movable member 32. It becomes possible to do.
In the above-described embodiment, an example in which a two-stage opening / closing mechanism including the first and second opening / closing members 40A and 40B is provided has been described, but it is needless to say that three or more opening / closing mechanisms may be provided.

As described above, according to each embodiment of the present invention, instead of a conventional movable decorative body that is not easily changed, such as simply moving on the game area or moving in and out of the game area, it is greatly deformed after moving. Since the configuration is added, it is possible to cause a significant change in the game content and prevent the player from feeling bored. That is, the movable decorative body is a main body part that simply operates, an opening / closing member that is attached to the main body part, and that greatly changes in the overall shape of the movable panel surface part by appearing and opening / closing according to the operation change of the main body part, The opening / closing member is concealed by the main movable member when it is closed and cannot be visually recognized, but suddenly expands and appears on the outer peripheral edge of the main movable member when opened. For this reason, the player can enjoy the game by illusioning that the main movable member suddenly becomes larger or has changed to a different large shape.
The movable decorative body 31 is configured to be movable back and forth between a retracted position that does not interfere with the display surface of the symbol display device 7 disposed on the game board surface and a protruding position that hides at least a part of the display surface. For this reason, in the state where the movable decorative body 31 is positioned on the front surface of the display surface, it is possible to realize a specific effect by collaboration between the image displayed on the display surface and the operation of the movable decorative body.
Further, the main movable member 32 may appear on the front surface of the game board surface (the symbol display device 7), and then the opening / closing member may be moved in and out, or the main movable member may be moved from outside the game board surface into the game board surface. In the process, the opening / closing member may be moved in and out or rotated.
