Description

  The present invention relates to an effect device for a gaming machine including a movable accessory, and more particularly to an effect device for a game machine including an accessory having a movable part that is arranged in front of an image display screen and is movable at a plurality of continuous joints.

  In gaming machines such as pachinko machines, there are a wide variety of machines in which a central player device provided so as to surround an image display screen such as a liquid crystal panel is arranged at the center of the game board surface. Since the game content of the gaming machine, game information, and the like are displayed on the image display screen, the player who is playing the game is the most attentioned part. In view of this, on the image display screen and its surroundings, various tastes that attract the interest of the player are elaborated, and this is the part that most strongly reflects the characteristics of the gaming machine. For example, there is a central bonus device in which a movable accessory that moves in a three-dimensional space and produces a game is arranged in the vicinity of an image display screen that produces a game by two-dimensional display.

  Here, the movable accessory accommodated in the central accessory device must move in the limited narrow space and accommodate the drive mechanism for the movement, and therefore, linear motion such as forward and backward movement and rotational motion. There were many things that do relatively simple exercises. For example, even in the case of a movable accessory representing an animal having a joint, the movable member only rotates in one joint, and has not imitated the actual appearance of an animal.

Patent Document 1 discloses a movable accessory that imitates a human body having two joints of a shoulder and an arm while swinging the arm. The drive source is installed at a location away from the movable member, and the movable member biased by the spring is pulled by the wire drawn from the drive source and reversibly moves. The wire is accommodated in the elastic cylinder member at the joint portion, and the force from the drive source is smoothly transmitted to the movable member separated from the drive source.
JP-A-2005-334499

  There is an effect device for a gaming machine including a movable accessory arranged in front of an image display having an image display screen and capable of performing exercise in association with an image displayed on the image display. In recent years, the performance of the image display has improved, and if the movement of the movable accessory remains simple, even if it is related to the image displayed on the image display, the effect by the image display is hindered. It will end up. Therefore, instead of a movable accessory that performs simple linear motion or rotational motion, a movable accessory that has a complex movement having a movable portion connected by a plurality of continuous joints has been demanded.

  In order to drive a movable member connected by a plurality of continuous joints with a drive source provided at a position away from the movable member, such as the movable accessory disclosed in Patent Document 1, motion obtained by the drive source It is necessary to provide a mechanism for transmitting to the movable part farthest from the drive source.

  The present invention includes a movable member having a plurality of movable members connected by a plurality of continuous joints and capable of driving the plurality of movable members with a single drive source provided outside the movable member. An object of the present invention is to provide an effect device for a gaming machine.

  An effect device for a gaming machine according to the present invention is an effect device for a gaming machine including an image display having an image display screen and a movable accessory arranged in front of the image display screen. A base member fixed to the gaming machine, a main link member rotatably connected to the base member at one end, and a slave connected to the other end of the main link member rotatably at one end. It includes a link member, and a gear drive mechanism that defines a relative angular position among the base member, the main link member, and the slave link member.

  The relative angular position of the main link member and the sub link member connected by the two joints provided on both sides of the main link member is determined by the gear drive mechanism. Therefore, the main link member and the slave link member can be driven with respect to the base member by a single drive source that operates the gear drive mechanism. Moreover, since the relative angular position between the main link member, the secondary link member, and the base member is determined by the gear, reversible movement is possible and the movable range of the relative movement between the link members can be easily performed. Since it can be set and there is no slip, the relative angular position relationship between the links is uniquely determined even by repeated operations.

BEST MODE FOR CARRYING OUT THE INVENTION

  One embodiment of the effect device for a gaming machine according to the present invention includes an image display having an image display screen and a movable accessory arranged in front of the image display screen. The movable combination can move in association with the image displayed on the image display screen. Such a movable accessory includes a base member, a main link member, a secondary link member, and a terminal link member connected by a continuous joint. The base member, the main link member, the secondary link member, and the terminal link member rotate in a plane parallel to the image display surface (game board surface), that is, in a plane parallel to each other.

  The base member is a member for fixing the movable accessory to the gaming machine, and a first gear is integrally formed at the tip portion. The main link member is rotatably coupled to the tip of the base member at the first end. The slave link member is rotatably coupled to the second end portion (the end portion on the opposite side of the first end portion) of the main link member at the first end portion. The 2nd gear fixed to the front-end | tip part of the extension shaft fixedly provided on the secondary link member is rotatable on the main link. That is, by the extension shaft, the rotation surface of the main link member and the rotation surface of the sub link member are parallel to each other but are separated from each other in the direction perpendicular to the image display surface (game board surface). Between the first gear and the second gear, a torque transmission gear train including a plurality of torque transmission gears meshed in series is arranged. The torque transmission gear is carried on the main link member. When the link member rotates in the direction opposite to the direction in which the main link member rotates, the torque transmission gear train has an odd number of gears in series.

  The end link member is rotatably coupled to the second end portion (end portion opposite to the first end portion) of the slave link member. The fixed gear fixed to the tip portion of the second extension shaft fixed on the main link member is rotatable relative to the sub link member. That is, the rotation surface of the main link member and the rotation surface of the slave link member are parallel to each other in the direction perpendicular to the image display surface (game board surface) by the second extension shaft as well as the extension shaft. It is. A terminal gear is fixed to one end of the terminal link member. Here, a second torque transmission gear train composed of a plurality of torque transmission gears meshed in series is arranged between the fixed gear and the terminal gear. The torque transmission gear is carried on the end link member. When the terminal link member rotates in the same direction as the sub link member rotates, the second torque transmission gear train has an even number of gears in series.

  In the above, when the main link member is rotated with respect to the base member by a single drive mechanism, the main link member is relative to the base member, the slave link member is relative to the main link member, and the terminal link member is slave. The relative angular position with respect to the link member is determined.

  Furthermore, one embodiment of the above-described game machine effect device according to the present invention will be described in detail with reference to FIGS.

  In particular, as shown in FIG. 1, the gaming machine 1 is a bullet ball gaming machine in which a game ball is launched toward a game area of the game board 2 by a player's handle operation, such as a pachinko machine. At the center of the game board 2, a central accessory device 3 with a decoration is installed. The central accessory device 3 has an opening directed forward, and is physically separated from the game board 2 by a partition, and a part of the inside of the partition is further than the surface of the game board 2. There is a central accessory space 3a provided so as to be located rearward. A window portion 4 that is a substantially rectangular through hole is provided at the rear end of the central accessory space 3a.

  The image display 5 including a liquid crystal panel is disposed so that the image display screen is substantially parallel to the surface of the game board 2 and the window 4 is closed. A moving image can be displayed on the image display 5 by the image control unit 91 that has received a signal from the CPU 90.

  In the central accessory space 3a, a stage 6 is provided below the window portion 4 so as to extend in a substantially horizontal plane and retain a game ball thereon. The stage 6 undulates vertically in the longitudinal direction along the game board 2, and extends in the direction crossing the top of the mountain at the center in the longitudinal direction, that is, the direction perpendicular to the game board 2. A groove 6a is formed.

  On the side surface of the central bonus device 3, there is a winning opening 7 for guiding the game ball into the central bonus space 3a. The winning opening 7 communicates with the opening of the side wall of the central bonus space 3a through a game ball guide passage (not shown). That is, the game ball that has entered the winning opening 7 is guided to the inside of the central bonus space 3a from the opening (not shown) provided on the side wall of the central bonus device 3 through the gaming ball guide passage and onto the stage 6. It falls. A part of the game balls dropped on the stage 6 falls into the groove 6 a and falls from the central accessory device 3 in a direction perpendicular to the game board 2. A part of the game balls falls from the portion other than the groove 6a to the lower side of the central accessory device 3.

  On the left side of the central accessory device 3 toward the game board 2 is a winning opening 8a having an opening provided so as to receive a game ball falling on the game board. Further, a start winning opening (chucker) 8 having an upward opening is provided below the groove 6 a of the stage 6 of the central accessory device 3. The game ball discharged from the groove 6a of the stage 6 of the central accessory device 3 in the direction perpendicular to the game board 2 falls on the start winning opening 8 with a high probability. When a game ball enters the start winning opening 8, a sensor (not shown) detects this and a lottery is performed inside the CPU 90. As a result of the lottery, when a “big hit” is obtained, the fact is displayed on the image display 5 and the movable accessory 30 operates to open the special prize opening device 9 as will be described later. The start winning opening 8 is provided with a movable member. Normally, the upper ends of the two movable members are close to each other, and the start winning opening 8 is closed. On the other hand, when a game ball enters the winning opening 8a, a lottery is performed in the CPU 90. When the start winning opening 8 is opened so that the upper end of the movable member is separated with a certain probability by this lottery, the game ball easily enters the starting winning opening 8. In addition, when the predetermined time has elapsed, the movable member of the start winning opening 8 returns to the original state so that the upper end portion thereof approaches again.

  Below the start winning opening 8, a large winning opening apparatus 9 elongated in the horizontal direction is provided. In the normal game state, the special prize opening device 9 closes the special prize opening 9a provided in the game board 2 with a lid integrated with the game board surface. On the other hand, as a result of the internal lottery performed by the CPU 90 when the game ball enters the start winning opening 8 and obtains a “big hit” and shifts to the special game state, the lid body turns its upper end toward the front side. While moving and jumping out from the game board 2, the special winning opening 9a is opened for a predetermined time. Since the big prize opening device 9 is elongated in the horizontal direction, most of the game balls falling on the game board 2 are received by the lid that has jumped out of the game board 2 and taken into the big prize opening 9a. A certain number of prize balls are paid back to the player every time one game ball passes through the special winning opening 9a.

  At the bottom of the game area of the game board 2, there is provided a discharge port 10 for collecting the game balls launched into the game area into the game machine 1 as final “offset balls”. Note that nails (not shown) are appropriately planted on the game board 2 to define the movement path of the game balls.

  Further, the central accessory device 3 will be described.

  As shown in FIG. 2, the central bonus device 3 has a central bonus space 3 a, and the central bonus space 3 a is physically separated by a partition on the game board 2. The image display 5 is disposed behind the substantially rectangular window 4 at the rear end of the central accessory space 3a, and a moving image can be displayed by the image control unit 91 that receives a signal from the CPU 90. A movable accessory 30 in the shape of a person is installed in the central accessory space 3a and in front of the right side toward the image display 5. The movable accessory 30 is driven by a drive control unit 92 that receives a signal from the CPU 90. Specifically, the movable accessory 30 is driven in accordance with an image displayed on the image display 5 and is driven by rotating and moving four members connected by three consecutive joints relative to each other. It is a thing. For example, the movable accessory 30 is an accessory in which a man with a cigarette stands standing sideways with a lighter. When a signal is sent from the CPU 90 to the drive control unit 91 under predetermined game conditions, the drive control unit 91 starts to move the movable accessory 30. The movable accessory 30 is a cigarette in which the body 32 is tilted forward from the waist 31 and the left upper arm 33 is lifted upward, and the arm tip 34 is bent so as to approach the face, and a lighter held in the hand is held in the mouth. The operation is performed so as to be close to. This series of operations is performed simultaneously and continuously by a mechanism described later.

  Referring also to FIG. 3, the base member 41, the main link member 51, the secondary link member 61, and the terminal link member 71 are connected by a first joint 39a, a second joint 39b, and a third joint 39c, respectively. Yes. On the base member 41, the main link member 51, the sub link member 61, and the terminal link member 71, clothes as shown in FIG. 2 are covered so as to cover them. Each member forms a skeleton of the movable accessory 30, but these are not visible to the player. By moving each member relatively at the joint, the movable accessory 30 wearing clothes moves as if it operates as described above.

  The base member 41 corresponds to the skeleton of the waist 31 portion of the movable accessory 30 (see FIG. 2). The base member 41 has a role of fixing the movable accessory 30 to the central accessory device 3, and the base member 41 does not move even if the movable accessory 30 moves.

  The main link member 51 corresponds to the skeleton of the body 32 portion of the movable accessory 41 (see FIG. 2). One end of the main link member 51 is pivotally supported at the upper end of the base member 41, and the main link member 51 is rotatable around the first joint 39a. When the main link member 51 rotates in the counterclockwise direction (solid line → broken line, arrow R1 direction) about the first joint 39a in the plane of FIG. 3, the portion of the body 32 above the waist 31 of the movable accessory 30 Is tilted forward.

  The sub link member 61 corresponds to the skeleton of the arm 33 portion of the movable accessory 30 (see FIG. 2). The sub link member 61 is pivotally supported at one end so as to hang from the upper end of the main link member 51, and rotates around the second joint 39 b corresponding to the left shoulder portion of the movable accessory 30. It is free to move. When the secondary link member 61 is rotated in the clockwise direction (in the direction of the arrow R2) around the second joint 39b in the direction away from the main link member 51, that is, in the plane of FIG. 3, the upper arm 33 of the movable accessory 30 is moved. It is pulled up upwards.

  The end link member 71 corresponds to the skeleton of the arm tip 34 of the movable accessory 30 (see FIG. 2). One end of the end link member 71 is pivotally supported by the lower end of the sub link member 61, and is rotatable around the third joint 39 c corresponding to the elbow portion of the movable accessory 30. When the end link member 71 is rotated in the direction in which the end link member 71 approaches the slave link member 61, that is, in the plane of FIG. 3 around the third joint 39c in the clockwise direction (arrow R3 direction), the arm tip 34 of the movable accessory 30 is obtained. Is lifted upward, and the lighter held in the hand at the tip of the arm tip 34 approaches the face of the movable accessory 30.

  The relative angular position among the base member 41, the main link member 51, the secondary link member 61, and the terminal link member 71 is determined by the gear drive mechanism, and the movable accessory 30 moves. The gear drive mechanism will be described in detail with reference to FIGS.

  In particular, as shown in FIGS. 4 and 6, the base member 41 has a through hole 42 having a circular cross section. A first gear 43 is formed at the upper end of the base member 41. The first gear 43 is formed of gear teeth directed upward by about 1/8 arc with the through hole 42 as the center. An arcuate guide groove 44 is formed between the through-hole 42 and the first gear 43. The base member 41 is screwed to the central accessory device 3 at a mounting portion 45 extending rearward.

  As shown in FIGS. 4 to 6, the main link member 51 has a rotating shaft 52 at one end, and the rotating shaft 52 extends through the plate-like main link member 51. A rotating shaft 52 extending from the surface 51 a facing the front side of the main link member 51 toward the front side is inserted into the through hole 42 of the base member 41. In addition, on the surface 51 a facing the front side of the main link member 51, a guide pin 53 protruding toward the near side is implanted above the rotating shaft 52. The guide pin 53 is slidable in the guide groove 44 of the base member 41. A driving gear 21 having a gear tooth formed on a fan-shaped tip is fixed to the rear end of the rotating shaft 52 extending rearward from the surface facing the rear of the main link member 51. The drive gear 21 meshes with a pinion gear 22 a attached to the output shaft of the motor 22 fixed to the central accessory device 3. The rotation of the motor 22 is controlled by a drive control unit 92 that receives a signal from the CPU 90.

  As described above, the main link member 51 can rotate with respect to the base member 41 with the guide pin 53 sliding in the guide groove 44 of the base member 41 around the through hole 42 and the rotation shaft 52 of the base member 41. is there. Note that the rotation range of the main link member 51 relative to the base member 41 is restricted by the guide groove 44 and the guide pin 53. That is, the main link member 51 rotates from a position (see FIG. 4) that extends straight upward from the base member 41 to a position (see FIG. 6) inclined about 30 degrees counterclockwise when viewed from the front. To do.

  Three gear fixing pins 54a, 54b and 54c are planted on the surface 51a facing the front side of the main link member 51 in a straight line in the extending direction of the main link member 51. The gear fixing pins 54a, 54b and 54c are rotatably fitted with connecting gears 55a, 55b and 55c having the rotation shafts as rotation shafts, and the gear teeth mesh with each other to form a torque transmission gear train. . Further, the connecting gear 55 a meshes with the first gear 43.

  In particular, as shown in FIG. 5, a protective cover member 51b is attached to the main link member 51 so as to cover the connecting gears 55a, 55b, 55c and the like disposed on the front surface 51a. At the center of the bag-like end near the upper end of the cover member 51b, there is a mounting portion 56 that is formed to project toward the front in a cylindrical shape. A part of a circle is cut off at the center of the mounting portion 56. A through-hole 56a having a different shape is formed.

  4 to 6 again, the secondary link member 61 is a plate-like body and has a through hole 62 at one end thereof. The cylindrical attachment portion 56 of the protective cover member 51 b combined with the main link member 51 is inserted into the through hole 62 of the sub link member 61. Thereby, the sub link member 61 is rotatable with respect to the protective cover member 51 b, that is, with respect to the main link member 51.

  Two gear fixing pins 63a and 63b are planted in a straight line in the extending direction of the sub link member 61 on the surface 61a facing the sub link member 61. The gear fixing pins 63a and 63b are rotatably fitted with connecting gears 64a and 64b having the rotation shafts as rotation shafts, and mesh with each other to form a torque transmission gear train.

  In particular, as shown in FIG. 5, the connecting member 65 is a substantially cylindrical hollow member having a through hole 66 in the center. An extension shaft 67 of a protective cover member 61b for a secondary link member 61, which will be described later, is inserted into the through hole 66 of the connecting member 65. The front end of the connecting member 65 has a fixed gear 65a in which gear teeth facing outward are formed on a part of the circumferential portion. The (second) extension shaft 65b behind the fixed gear 65a of the connecting member 65 is molded into a cross-sectional shape obtained by cutting a part of a circle in accordance with the shape of the through hole 56a of the protective cover member 51b. The connecting member 65 is inserted through the through hole 62 of the secondary link member 61 and is further inserted into the through hole 56a of the protective cover member 51b. Because of the cross-sectional shape of the extension shaft 65b of the connecting member 65, the protective cover member 51b and the connecting member 65 cannot rotate relative to each other and can rotate together. The sub link member 61 is rotatable with respect to the connecting member 65.

  A protective cover member 61b is also attached to the secondary link member 61 so as to cover the connecting gears 64a and 64b disposed on the surface 61a facing the front side. An extension shaft 67 having a circular cross section extends rearward at the center of the surface facing the rear of the circular end near the upper end of the protective cover member 61b. The extension shaft 67 is inserted through the through-hole 66 of the connecting member 65, the through-hole 62 of the secondary link member 61, and the through-hole 56a of the protective cover member 51b. A second gear 68 having gear teeth directed is attached. The second gear 68 is positioned on the main link member 51 and meshes with the connecting gear 55c (see FIGS. 4 and 6). That is, the second gear 68 is integrally connected to the protective cover member 61b and the secondary link member 61.

  Referring to FIG. 5, a connecting pin 69 extending toward the near side is planted at the lower end of the surface 61 a facing the near side of the sub link member 61. Referring to FIGS. 4 to 6 again, an end point link member 71 is attached to the connecting pin 69 so as to cover it. The end link member 71 has a hammer-shaped tip, and is provided at one end thereof with a terminal gear 72 having gear teeth facing outward only at a part of the circumference. The terminal gear 72 meshes with a connecting gear 64b that is rotatably mounted on the slave link member 61.

  Next, the operation of one embodiment of the above-described gaming machine effect device according to the present invention will be described in detail with reference to FIGS.

  For example, as a result of the internal lottery in the CPU 90, when the “big hit” is obtained and the game state shifts from the normal game state to the special game state, the CPU 90 sends a signal to the image control unit 91 so as to display a specific symbol. This is displayed on the display 5. At the same time, the CPU 90 sends a signal to the drive control unit 92 to drive the movable accessory 30. Note that the image control unit 91 displays images that continuously change in accordance with the movement of the movable accessory 30 described below.

  As shown in FIGS. 2 and 4, in the normal gaming state, the movable accessory 30 is in an upright state with the arm tip 34 lightly bent. When a signal is sent from the CPU 90 to the drive control unit 92, the drive control unit 92 rotates the pinion gear 22a of the motor 22 in the clockwise direction in FIG. 4 and slowly rotates the drive gear 21 in the counterclockwise direction. In FIG. 4, the pinion gear 22a and the drive gear 21 are directly meshed with each other, but a reduction gear or the like may be inserted between them. The motor 22 may be a bidirectional solenoid.

  Referring also to FIG. 6, when the drive gear 21 rotates counterclockwise, the main link member 51 has the guide pin 53 and the guide groove 44 of the base member 41 around the through hole 42 and the rotation shaft 52 of the base member 41. While being slid, the base member 41 is rotated counterclockwise. That is, the part of the body 32 at the upper part from the waist 31 of the movable accessory 30 tilts forward.

  When the main link member 51 rotates with respect to the base member 41, the connection gear 55 a is rotated counterclockwise by the first gear 43. Since there are an odd number of connection gears 55a, 55b and 55c, when the connection gear 55a rotates counterclockwise, the connection gear 55c rotates in the same direction, that is, counterclockwise, at the end of the torque transmission gear train. As a result, the second gear 68 rotates clockwise.

  When the second gear 68 rotates in the clockwise direction, the slave link member 61 connected through the extension shaft 67 rotates in the clockwise direction relative to the main link member 51. That is, the sub link member 61 rotates in a direction away from the main link member 51 (see R2 in FIG. 3), and the movable accessory 30 appears to pull up the left upper arm 33 upward.

  When the slave link member 61 rotates in the clockwise direction relative to the main link member 51, the connecting member 65 that is integrally connected via the main link member 51 and the cover member 51b is also connected to the slave link member 61. It rotates relative to it. That is, the fixed gear 65a is rotated counterclockwise relative to the slave link member 61. When the fixed gear 65a rotates in the counterclockwise direction relative to the slave link member 61, there are an even number of torque transmission gear trains of the coupling gears 64a and 64b meshing with the fixed link member 65a. The gear 64b rotates in the reverse direction, that is, counterclockwise. Through the end gear 72, the end link member 71 rotates in the clockwise direction with respect to the slave link member 61, that is, in the direction in which it approaches (see R3 in FIG. 3). As a result, the movable accessory 30 bends the arm tip 34 toward the face and brings the lighter held in the hand corresponding to the upper portion of the hammer at the tip of the end link member 71 closer to the cigarette in the mouth. It appears to be moving.

  Here, as described above, the movement of the terminal link member 71 is obtained by the connecting member 65 that is integrally connected via the main link member 51 and the cover member 51b. That is, the terminal link member 71 and the motor 22 as a drive source are not directly connected by the torque transmission gear train. In a movable member that is separated from the drive source by a certain distance or more, if the drive source and the movable part are directly connected only by the torque transmission gear train, the number of gears increases. On the other hand, the movable accessory can be made compact by driving the movable portion ahead by the torque transmission gear train using the movement caused by the relative movement of the movable members as a drive source. In addition, even a movable accessory having a plurality of continuous joints can be reduced in failure without being distorted even if it is repeatedly moved to the movable portion at the end.

  Thus, a series of operations of the movable accessory 30 is finished, and the motor 22 is stopped. From this state, when the drive control unit 92 rotates the motor 22 in the opposite direction, that is, in the counterclockwise direction, the movable accessory 30 returns to the upright state again, but only the above operation is performed in the opposite direction. Therefore, it will not be described in detail.

  According to this embodiment, since the movable part connected by a plurality of continuous joints can be moved by a drive source such as a single motor, a drive source is provided for each joint like a conventional movable accessory. The size can be made smaller than the movable accessory that has driven each movable part. In addition, when the movable parts are connected by a pulley and a belt wound around the pulley as in the case of a conventional movable accessory, the relative angular position of each movable part is caused by sliding between the pulley and the belt. It was not possible to move repeatedly due to madness, or “chatter” occurred, and it was impossible to obtain a continuous and smooth movement of the movable accessory. However, according to the present embodiment, each movable part is connected to a drive source by a gear train, so that the angular position can be relatively strictly determined, and a continuous and smooth movement of the movable accessory can be obtained. I can do it. In addition, stable operation can be performed repeatedly.
