However, this is merely an example, and it is of course possible to arrange these indicators in the game area 3a of the game board 3.
The movable panel surface component A according to the present invention is roughly configured from a gimmick 30 having a large shape developed on the entire panel surface and a gimmick drive mechanism 50.
The game board 3 according to this example is at least partially made of a transparent material such as acrylic, and the gimmick 30 and the drive mechanism 50 are disposed on the back side of the game board. For this reason, the player can see the operation of the gimmick located on the back side through the transparent game board (transparent game b).

The gimmick 30 according to the present embodiment includes five gimmick piece units U configured by combining a plurality (two in this example) of substantially rectangular gimmick pieces 31 and 32 in a V shape, When the gimmick piece unit U is in the coupled state, a star-shaped completed shape as shown in FIGS. 1 and 6 is formed, and when in the separated state (disassembled state), the completed shape is disassembled as shown in FIGS. Form a shape.
Each gimmick piece unit U is deformed alternately between a completed shape and a disassembled shape by driving by the driving mechanism 50.
The drive mechanism 50 includes an annular and large-diameter drive gear 51 rotatably supported by a base member 7 assembled to the game board 3 or the frame 2, and a coaxial and drive gear on the front side of the drive gear 51. A disk-shaped and large-diameter driven gear 60 that is rotatably arranged and rotatably supported, a drive source (motor 55a, output gear 55b) 55 that rotationally drives the drive gear 51, and rotational drive of the drive gear 51 A transmission member 70 that transmits force to the driven gear 60, a plurality of cam slits 65a, 65b, 65c, and 65d that are formed through the board surface 60a of the driven gear 60, and the drive gear 51 and is fixed to the outermost diameter side. A fixed pin 66 loosely fitted in the cam slit 65a. The fixed pin 66 and the movable pins 34, 31a and 32a provided on the gimmick pieces 31 and 32 are respectively connected to the cam slits 65a. It is configured to move within the cam slits loosely fitted in 65d. In this example, the fixing pin 66 is rotatably supported by one gimmick piece 31 constituting each gimmick piece unit U. As will be described later, by rotating only the driven gear 60 using the transmission member 70 with the drive gear 51 stopped, the fixed pin 66 supported by the gimmick piece 31 rotates around the cam slit 65a. In this process, the movable pins 34, 31a, 32a, which are rotatably supported by the other parts of the gimmick pieces 31, 32, move along the other cam slits. Operates along a defined trajectory.
The disk-shaped drive gear 51 is supported at its outer peripheral gear portion by rotation guide members 56 provided at four locations so as to rotate around its center point C. The rotation guide member 56 includes a guide gear 56a that guides rotation of the drive gear 51 while meshing with the outer peripheral gear portion of the drive gear 51, and a support member 56b that rotatably supports the guide gear 56a. Yes.

On the other hand, the driven gear 60 is relatively moved in the circumferential direction in the cam slit 65a by fitting the fixed pin 66 projecting from the drive gear 51 into the outermost cam slit 65a provided on the board surface 60a. Thus, the center point C can be rotated as a center. That is, since the cam slit 65 a has a concentric locus with the drive gear 51 and the driven gear 60, the driven gear 60 rotates coaxially with the drive gear 51. The cam slit 65a is provided at five locations along the circumferential direction of the driven gear, and the fixed pin 66 is inserted into each cam slit 65a. Therefore, the driven gear is centered on the central point C common to the drive gear 51. The cam slit 65a can be rotated coaxially within the range of the circumferential length.
Each gimmick piece unit U having the same configuration has a structure in which two gimmick pieces 31 and 32 are connected in a V shape and can be freely opened and closed, and both gimmicks are provided at a portion corresponding to the top of the V shape. A shaft support portion 33 is provided to support the pieces 31 and 32 so as to be openable and closable.

The structure around the fixed pin will be described with reference to FIG. 4. A triangular connection plate 52 is disposed on the front side of the first cam slit 65 a, and holes 52 a and 52 b are formed at three top portions of the connection plate 52. , 52c are formed through. A fixing pin 66 is inserted into one hole 52a, and is fixed to an appropriate position of the drive gear 51 through the first cam slit 65a. The pin 33a which comprises the axial support part 33 of the gimmick piece unit U is fastened to the other hole 52b. Further, the other hole 52c supports the movable pin 34 that is loosely fitted in the second cam slit 65b located on the inner diameter side. In this example, the movable pin 34 is provided in the vicinity of the end of one gimmick piece 32, while the other movable pin 31a provided in the substantially middle portion of the gimmick piece 31 is loosely fitted in the third cam slit 65c. Furthermore, the movable pin 31b provided in the substantially middle part of the gimmick piece 32 is loosely fitted in the fourth cam slit 65d. The connection plate 52 is also formed with a hole through which the harness 36 for supplying power to the LED 35 mounted on each gimmick piece unit U is inserted.
The driven gear 60 rotates integrally with the drive gear by the driving force transmitted from the small gear group constituting the transmission member 70 when the drive gear 51 rotates. On the other hand, when the drive gear 51 is stopped, the transmission member 70 is operated to rotate the driven gear 60 independently, so that the fixed pin 66 and the movable pins 34, 31a, 32a are moved along the cam slits 65a to 65d. As a result of the relative movement, the V-shaped gimmick pieces 31 and 32 can be moved while being opened / closed around the shaft support 33. Each gimmick piece 31, 32 opens and closes and moves along a predetermined trajectory as the fixed pin and each movable pin move along each cam slit, so that the gimmick 30 is deformed between a completed shape and a disassembled shape. Can be made. Regardless of the deformation state of the gimmick piece, by rotating the drive gear 51, the driven gear 60 rotates integrally with the drive gear, and the gimmick 30 mounted on the board surface of the driven gear also rotates integrally.

As shown in each drawing, the transmission member 70 is pivotally supported by a base member 7 so that a fixed shaft portion 71a provided at one end portion (inner diameter side end portion) is pivoted, and swings about the fixed shaft portion 71a. A substantially L-shaped link piece 71, a substantially L-shaped link piece 72 in which a movable small gear 74a supported at one end is meshed with the driven gear 60, and the link pieces 71 and 72 are rotatably supported by the link pieces 71 and 72, respectively. The small gear trains 73 (73a, 73b, 73c), 74 (74a, 74b, 74c) meshed with each other and the small gears 73c, 74c located at the outer diameter side end portions are arranged between the two small gears. An intermediate gear 75 to be connected, and a connecting plate 76 that supports the rotation shafts of the intermediate gear 75 and the small gears 73c and 74c, respectively. The connecting plate 76 maintains a state where the link pieces 71 and 72 are connected without being separated, and opens and closes (rotates) the link pieces 71 and 72 around the rotation shafts of the small gears 73c and 74c. It plays a supporting role as possible.
Each of the link pieces 71 and 72 of this example is arranged one by one in the front-rear positional relationship with each small gear interposed therebetween, and each small gear is arranged in a sandwich between the link pieces. Each small gear is rotatably supported.

A fixed small gear 73a that always meshes with the drive gear 51 is rotatably supported on the fixed shaft portion 71a, and the fixed small gear 73a rotates at a fixed position on the base member 7. A movable small gear 74 a rotatably supported by a shaft portion 72 a provided at one end of the link piece 72 is always meshed with the driven gear 60. Accordingly, when the drive gear 51 is rotationally driven, the driving force is sequentially transmitted from the fixed small gear 73a to the other small gears 73b and 73c, the intermediate gear 75, the small gears 74c, 74b and 74a, and the driven gear 60. Reverse the driven gear forward and backward.
The fixed small gear 73a meshes with the gear portion on the outer periphery of the drive gear without meshing with the driven gear 60, and the movable small gear 74a is fixed with the gear portion on the outer periphery of the driven gear without meshing with the drive gear. The front and rear positions of the small gear 73a and the movable small gear 74a are shifted.
The other end of each link piece 71, 72 is a gear-like portion 71b, 72b, and the opening angle of each link piece intersecting in a V-shape is changed by the engagement of each gear-like portion 71b, 72b. Is possible. That is, the opening angle between the link pieces is changed by changing the distance L of the shaft portion 72a of the link piece 72 with respect to the fixed shaft portion 71a of each link piece 71 whose position is fixed while the drive gear is stopped. Can do. In this way, by changing the positional relationship between the link pieces 71 and 72 to change the opening angle of the link piece from wide to narrow, the movable small gear 74a is moved closer to and away from the fixed small gear 73a, and the movable small gear 74a is moved. Only the driven gear 60 can be rotated in the process of moving back and forth along the outer periphery of the driven gear 60.

The shaft portion 72 a of the link piece 72 advances and retreats along the outer periphery of the driven gear 60 along a predetermined locus along the guide slit 8 a in an arc shape provided in the guide member 8 fixed to the base member 7.
Further, an operation member 77 is fixed in a support hole 72c provided at one end of the link piece 72, and this operation member 77 is moved forward and backward along a circular arc track along the outer peripheral edge of the drive gear 51 by a motor and a solenoid. Thus, the transmission member 70 can be deformed from the state shown in FIG. 6 to the state shown in FIG. 8 through the state shown in FIG. The operation member 77 moves along a predetermined trajectory along the guide slit 7 a provided in the base member 7.
Since the transmission member 70 has the above-described configuration, when the drive gear 51 is stopped, the transmission member 70 is extended in the order of the postures shown in FIGS. The fixed pin 66 and the movable pins 34, 31a and 32a move relative to each other along the cam slits 65a to 65d to move the gimmick pieces 31 and 32 in the gathering direction so that the completed shape of the gimmick 30 is obtained. Form. Further, when the drive gear 51 is stopped, the transmission member 70 is contracted in the reverse direction in the order of the postures of FIGS. 6, 7, and 8, so that the driven gear is rotated in the other direction, and the cam slits are moved. The fixed pin and the movable pin are moved relative to each other in the other direction, and the gimmick pieces are moved away from each other to eliminate the completed shape of the gimmick.

11 (a) and 11 (b) and FIGS. 12 (a) and 12 (b) show the correspondence between the transmission member 70 and each gimmick piece unit U. As shown in FIG. When the movable small gear 74a is most separated, the gimmick piece units U are brought together to complete a star-shaped gimmick. On the other hand, when the movable small gear 74a is brought closest to the fixed small gear 73a as shown in FIG. 12, each gimmick piece unit U is separated to cancel the star-shaped gimmick shape. In the process of this deformation, it is easy to configure so that any gimmick piece unit does not interfere with the image display 11 and conceal it. For this reason, the area of the image display 11 can be arbitrarily enlarged and enlarged.
Further, since the gear portions on the outer periphery of the drive gear 51 and the driven gear 60 and the transmission member 70 are located along the outer periphery of the game board, they are concealed by a concealment member (not shown) so as not to be seen from the front of the transparent game board 3. Easy to do.
In any of the states of FIGS. 6, 7, and 8, when the drive gear 51 is rotated, each small gear that constitutes the transmission member rotates, so that the driven gear 60 rotates and is arranged on the surface of the driven gear 60. The gimmick piece unit U thus rotated rotates as it is.

Next, the structural example for exhibiting an electrical decoration effect by LED mounted in gimmick based on FIG. 13 and FIG. 14 is demonstrated.
A sleeve 80 is provided in a cylindrical shape on the rear surface of the drive gear 51, and two guide plates 81 are fixed to the outer peripheral surface of the sleeve 80 over the entire circumference. On the other hand, a sliding electrode 86 made of a leaf spring is connected to the tip of a power supply harness 85 extending from the gaming machine main body, and the two sliding electrodes 86 are slidable with respect to each conductive plate 81. In contact (pressure contact). Furthermore, each conducting plate 81 is electrically connected to the LED 35 mounted on each gimmick piece 31, 32 via the harness 36 shown in FIG. For this reason, even when the drive gear 51 is rotating, power from a power source (not shown) can be supplied to the LED 35 via the sliding electrode 86, the conductive plate 81, and the harness 36 to cause the LED to emit light.
