  2. Description of the Related Art Conventionally, as an effect device used in a gaming machine, an effect device that performs various effects by moving a decorative body by the power of a motor is known. For example, the rendering device disclosed in Patent Document 1 uses a rack and pinion mechanism to reciprocate the decorative body in the vertical direction. In a state where the decorative body is in a steady position that is the upper end of the movable range, the decorative body is positioned above the display means for displaying various images. When the effect device drives the motor and moves the decorative body downward from the steady position, the display area of the display means is shielded by the decorative body. Thereby, a novel production can be performed. By using the rack and pinion mechanism, it is possible to manufacture an effect device that moves the decorative body up and down in a space-saving manner at a low cost.

JP 2010-162402 A

  When the decorative body is moved using the rack and pinion mechanism, a load is applied to the rack and the pinion depending on the weight of the decorative body to be moved. As a result, there are problems that the decorative body is inclined at an unintended angle, the decorative body swings around the rack during the performance, and the rack and pinion mechanism is deformed and damaged.

  The present invention provides an effect device capable of smoothly performing an effect operation using a rack and pinion mechanism by reducing the influence of a load due to the weight of a decorative body, and a gaming machine including the effect device. For the purpose.

An effect device according to a first aspect of the present invention is an effect device that includes a motor capable of rotating in the forward and reverse directions, and performs an effect by moving a decorative body from an origin position by the power of the motor, the power of the motor A first pinion that rotates about an axis by the first rack, and a first rack that is provided on the decorative body, extends in a vertical direction perpendicular to the rotation axis of the first pinion, and has teeth that mesh with the first pinion; A rising auxiliary rack having a tooth portion meshing with the first pinion and meshing with the opposite side of the first pinion to the side with which the first rack meshes, and a straight line from the first pinion on the rotation axis of the first pinion A connecting shaft that extends in a shape and rotates together with the first pinion, and is fixed to a position separated from the first pinion of the connecting shaft, and rotates together with the first pinion by the power of the motor That a second pinion is provided on the decorative body, extending in the first rack in a direction parallel and a second rack having teeth meshing with the second pinion.

In the effect device according to the first aspect, the two racks are provided in parallel on the decorative body. The first pinion that meshes with the first rack and the second pinion that meshes with the second rack are connected by a connecting shaft. When the motor is driven and the first pinion and the second pinion rotate, the first rack and the second rack move in the same direction by the same distance. Thereby, the said production | presentation apparatus can disperse | distribute the load by the weight of a decoration body to a 1st rack and a 2nd rack. As a result, it is possible to reduce the possibility of problems such as tilting of the decorative body, swinging of the decorative body during movement, deformation and breakage of the rack and pinion mechanism, and the like. Therefore, the effect device can execute a smooth effect with a simple configuration using only one motor. Further, when the decorative body is moved upward against the gravity, the ascending auxiliary rack assists the rotation of the first pinion. Therefore, the rendering device can move the decorative body smoothly by reducing the load applied to the motor.
The origin position of the decorative body may be located above display means for displaying an image in the gaming machine to which the effect device is attached. The motor may be arranged on the left side or the right side of the display unit. In this case, by arranging the motor to the left or right of the display means, the space in the center of the gaming machine can be used effectively, and the decoration body can be moved smoothly with one motor. it can.

  The stage device includes a contact part that contacts a part of the decorative body in a state where the decorative body is at the origin position, and a first magnet provided on one of the contact part and a part of the decorative body, You may further provide the 2nd magnet or magnetic body which is provided in the other of the said contact part and a part of said decoration body, and adsorb | sucks to said 1st magnet. In this case, when the decorative body moves to the origin position, which is the standby position of the decorative body when the performance is not performed, a part of the decorative body is attracted to the contact portion by magnetic force, and the decorative body is held at the origin position. . Therefore, the rendering device can reduce the possibility that the decorative body is separated from the origin position when the rendering is not performed. Therefore, for example, even when the player applies an impact to the gaming machine, the rendering device can firmly hold the decorative body at the origin position.

  The rendering device may further include a claw portion that protrudes from at least a part of the first rack and the second rack in a direction intersecting with an extending direction of the first rack and the second rack. The claw portion contacts the guide portion that guides the reciprocating movement of at least one of the first rack and the second rack when the decorative body moves to the end position of the movement range, so that the first rack And the engagement between the first pinion and the engagement between the second rack and the second pinion may be prevented. In this case, the effect device can reliably prevent the two sets of racks and the pinion from being disengaged by the claw portion. Therefore, the effect device does not lose its engagement and cannot perform the effect, and can perform the effect stably. Since the lengths of the first rack and the second rack need not be excessively long for the purpose of preventing the meshing from being disengaged, the apparatus can be reduced in size.

  The effect device is provided in the decoration body, an origin sensor that detects whether or not the decoration body is at an origin position, an end point sensor that detects whether or not the decoration body is at an end position of a movement range, and A first detected piece located at a location where the origin sensor is disposed when the decorative body is at the origin position, and the decorative body is provided at a position separated from the first detected piece, You may further provide the 2nd to-be-detected piece located in the arrangement | positioning location of the said end point sensor, when a body exists in an end point position. In this case, unlike the case where the origin sensor and the end point sensor detect the same detected piece, the degree of freedom of the arrangement positions of the origin sensor and the end point sensor can be increased. Therefore, the arrangement position of other members such as wiring is not restricted, and the space can be used effectively.

  A gaming machine according to a second aspect of the present invention includes the effect device and a control unit that controls execution of the effect by the effect device by controlling rotation of the motor. Therefore, the gaming machine can achieve the same effects as the effect device.

  As shown in FIG. 3, an opening 23 having a rectangular shape in front view is formed at the center of the rendering device 20. The rendering device 20 is arranged on the front side of the display device 10 so that the display area of the display device 10 (see FIG. 1) and the opening 23 coincide. Therefore, the player can visually recognize the display device 10 from the front side through the opening 23. The effect device 20 executes various effects mainly around the display area of the display device 10. Specifically, as shown in FIG. 4, the rendering device 20 includes a bombardment unit 24, a grenade rotation unit 26, and a decorative body movable unit 30 around the display area.

  The bombardment unit 24 is located at the lower left corner of the display area. The bombardment unit 24 includes a vibrating body 25 simulating the tip of a bazooka, and vibrates the vibrating body 25 by a solenoid (not shown) provided inside. The control unit of the pachinko machine 1 that controls the operation of the effect device 20 vibrates the vibrating body 25 and displays a bullet from the lower left to the upper right of the display area of the display device 10. As a result, the pachinko machine 1 can give a strong impression to the player as compared with the case where a bullet is displayed using only the display device 10.

  The grenade rotation unit 26 is located on the right side of the display area. The grenade rotating unit 26 includes a rotating body 27 having a shape of a grenade, and rotates the rotating body 27 by a motor (not shown) provided therein. A decoration different from the front decoration is provided on the back surface of the rotating body 27, and various effects can be executed by rotating the rotating body 27.

  The entire decorative body movable unit 30 is held by the middle frame 38. By attaching the middle frame 38 to the upper left of the support frame 21, the decorative body movable unit 30 is disposed so as to cover the left side and the upper side of the display area (see FIGS. 2 and 3). The decorative body movable unit 30 includes a decorative body 31 simulating the shape of a bomber. The decorative body movable unit 30 can perform an effect of moving the decorative body 31 up and down by driving a step motor 32 (see FIGS. 5 and 6) described later. Specifically, as shown in FIGS. 1 and 2, the origin position, which is the standby position of the decorative body 31 when the effect is not executed, is above the display area of the display device 10. Therefore, when the decorative body 31 is at the origin position, the player can visually recognize the entire display area of the display device 10 through the opening 23. When performing an effect, the effect device 20 drives the step motor 32 to move the decorative body 31 downward from the origin position. Thereby, the decorative body 31 is positioned in front of the display area to temporarily shield the display area, and a strong impression can be given to the player.

  With reference to FIG. 5 and FIG. 6, the structure for the decoration body movable part 30 to move the decoration body 31 up and down is demonstrated. As shown in FIGS. 5 and 6, the decorative body movable unit 30 includes a step motor 32. The step motor 32 is disposed at the left end of the decorative body movable unit 30. Therefore, when the rendering device 20 is mounted on the pachinko machine 1, the step motor 32 is positioned on the left side of the display device 10 (see FIG. 1) and is shielded by the decorative frame 22 (see FIG. 2) and the like. Since the display device 10 is arranged in the center of the pachinko machine 1, the space in the center is limited. However, by arranging the step motor 32 on the left side of the display device 10, the member in the center of the pachinko machine 1 Can be reduced. Furthermore, the rendering device 20 can smoothly move the decorative body 31 in the center of the pachinko machine 1 up and down while arranging the step motor 32 at the end by using two sets of rack and pinion mechanisms described later. it can.

  An output shaft of the step motor 32 extends rightward from the step motor 32, and a gear 33 is fixed to the output shaft. A first pinion 35 is meshed with the gear 33. The first pinion 35 is fixed to the left end portion of the connecting shaft 36 extending in the left-right direction, and rotates around the connecting shaft 36. Further, a second pinion 37 is fixed to the right end portion of the connecting shaft 36. The connecting shaft 36 is rotatably held by a part of the middle frame 38 (see FIG. 4) that supports the decorative body movable unit 30. When the step motor 32 rotates, the power of the step motor 32 is transmitted to the first pinion 35 via the gear 33, and the first pinion 35 rotates. When the first pinion 35 rotates, the connecting shaft 36 also rotates, so that the second pinion 37 also rotates by the same angle as the first pinion 35. The diameter and tooth shape of the first pinion 35 and the diameter and tooth shape of the second pinion 37 are the same.

  The decorative body 31 includes a main body 41, a movement guide part 42, and a connection part 43. The main body 41 is a portion forming the shape of the above-described bomber, and is located in the center of the pachinko machine 1 in a state where it can be seen from the front side. The movement guide unit 42 is positioned on the back side of the decorative frame 22 (see FIG. 2) so as not to be visually recognized by the player, and mainly guides the vertical movement of the decorative body 31. Specifically, the movement guide portion 42 is formed in a vertically long rectangle, and includes guide holes 44 in the vicinity of the upper end portion and in the vicinity of the lower end portion. 5 and 6, only the guide hole 44 near the upper end is shown. A guide shaft 45 extending in the vertical direction is inserted into the two guide holes 44. The guide shaft 45 is fixed to the middle frame 38 (see FIG. 4). As the moving guide portion 42 moves along the guide shaft 45, the decorative body 31 can move up and down smoothly. The connection unit 43 connects the main body 41 and the movement guide unit 42.

  A first rack 47 is fixed to the rear surface of the movement guide portion 42. The first rack 47 extends in the vertical direction, which is a direction perpendicular to the rotation axis of the first pinion 35. The teeth on the back side of the first rack 47 mesh with the first pinion 35. Therefore, when the first pinion 35 rotates, the moving guide portion 42 moves in the vertical direction along the guide shaft 45.

  Further, the decorative body movable unit 30 includes a shielding plate 49 having a substantially circular shape when viewed from the front. The shielding plate 49 is fixed to the middle frame 38 (see FIG. 4) on the back side of the main body 41 of the decorative body 31. The mechanism such as the second pinion 37 is shielded by the shielding plate 49. Further, a second rack 50 is fixed to the back surface of the main body 41. The second rack 50 extends in the vertical direction in parallel with the first rack 47, and the teeth on the back side of the second rack 50 mesh with the second pinion 37. A guide rail 51 for guiding the vertical movement of the second rack 50 is fixed to the back surface of the shielding plate 49 described above. Therefore, when the second pinion 37 rotates, the main body 41 moves in the vertical direction along the guide rail 51.

  Assuming that only one set of rack and pinion mechanism (for example, only the first pinion 35 and the first rack 47) is adopted in the effect device 20 as in the past, the decorative body 31 includes the movement guide portion 42 and the vicinity thereof. It will be supported only by the structure. Then, the weight of the decorative body 31 is concentrated on the movement guide portion 42, the guide shaft 45, the first pinion 35, the first rack 47, and the like. As a result, there is a possibility that problems such as the inclination of the decorative body 31, the swinging of the decorative body 31, and the deformation and breakage of the rack and pinion mechanism may occur. The effect device 20 according to the present embodiment can execute a smooth effect with a simple configuration using only one step motor 32 by using two sets of rack and pinion mechanisms.

  With reference to FIG. 5 and FIG. 6, a structure for holding the decorative body 31 at the origin position will be described. As shown in FIG. 6, the decorative body movable part 30 includes a contact part 53. The contact part 53 is fixed to the middle frame 38 (see FIG. 4) vertically above the movement guide part 42. A magnet 54 is fixed to the bottom surface of the contact portion 53. A magnet 55 is also fixed to the upper end portion of the movement guide portion 42 that is a part of the decorative body 31. When the effect device 20 drives the step motor 32 and moves the decorative body 31 to the origin position (the upper end of the movable range extending vertically), as shown in FIG. 5, the upper end of the movement guide portion 42 of the decorative body 31 is Contact the contact portion 53 fixed to the middle frame 38. As a result, the magnet 54 of the contact portion 53 and the magnet 55 of the movement guide portion 42 are attracted, and the decorative body 31 is firmly held at the origin position.

  With reference to FIG. 6, the structure for assisting the raising of the decorative body 31 is demonstrated. The decorative body movable unit 30 includes a tension spring 56. The tension spring 56 is interposed between the lower part of the movement guide part 42 which is a part of the decorative body 31 and the contact part 53 positioned above the movement guide part 42, and urges the movement guide part 42 upward. To do. Therefore, when the rendering device 20 raises the decorative body 31, the rising of the decorative body 31 is assisted by the tension spring 56.

  A structure for preventing the second rack 50 and the second pinion 37 from being detached will be described with reference to FIGS. As shown in FIG. 7, a claw portion 60 that protrudes forward (leftward in FIG. 7) that is perpendicular to the extending direction (vertical direction) of the second rack 50 is formed at the upper end portion of the second rack 50. Has been. A contact portion 61 that protrudes rearward is formed at the lower end of the guide rail 51 fixed to the shielding plate 49. As shown in FIG. 7, the claw portion 60 and the contact portion 61 are separated from each other when the decorative body 31 is at the origin position. As shown in FIG. 8, when the decorative body 31 moves to the end point position of the movement range, the claw portion 60 comes into contact with the contact portion 61, and the downward movement of the second rack 50 is restricted. Accordingly, it is possible to reliably prevent the meshing between the first rack 47 and the first pinion 35 and the meshing between the second rack 50 and the second pinion 37 from being released.

  A structure for detecting the position of the decorative body 31 will be described with reference to FIGS. 5, 6, 9, and 10. As shown in FIGS. 9 and 10, an origin sensor 63 that is an optical sensor is fixed to the upper front side of the middle frame 38 that supports the decorative body movable unit 30. In the middle frame 38, an end point sensor 64, which is an optical sensor, is fixed vertically below the fixed position of the origin sensor 63. As shown in FIG. 5, a plate-like first detection piece 66 is formed on the upper left side of the movement guide portion 42 of the decorative body 31. As shown in FIG. 6, a second detected piece 67 having the same shape as the first detected piece 66 is formed at the lower left portion of the movement guide portion 42.

  As shown in FIG. 5, when the decorative body 31 is at the origin position, the first detected piece 66 is located at the location where the origin sensor 63 is disposed. Therefore, the origin sensor 63 can detect whether or not the decorative body 31 is at the origin position depending on whether or not the first detected piece 66 is detected. In addition, as shown in FIG. 6, when the decorative body 31 is at the end point position, the second detected piece 67 is located at the location where the end point sensor 64 is disposed. Therefore, the end point sensor 64 can detect whether or not the decorative body 31 is at the end point position depending on whether or not the second detected piece 67 is detected.

  As shown in FIGS. 9 and 10, the first detected piece 66 and the second detected piece 67 are provided at positions separated in the vertical direction. Therefore, unlike the case where the origin sensor 63 and the end point sensor 64 detect the same detected piece, the degree of freedom of the arrangement positions of the origin sensor 63 and the end point sensor 64 can be increased. In the present embodiment, the distance between the origin sensor 63 and the end point sensor 64 is increased by providing the second detected piece 67 below the first detected piece 66. As a result, the space between the origin sensor 63 and the end point sensor 64 increases. In this space, a flexible wiring 70 that is electrically connected to the LEDs in the main body 41 of the decorative body 31 is disposed. As shown in FIGS. 9 and 10, when the decorative body 31 moves, the position of the flexible wiring 70 changes. However, since the space between the origin sensor 63 and the end point sensor 64 is wide, the flexible wiring 70 does not hinder the vertical movement of the decorative body 31.

  As described above, in the rendering device 20 of the present embodiment, the first rack 47 and the second rack 50 are provided on the decorative body 31 in parallel. The first pinion 35 that meshes with the first rack 47 and the second pinion 37 that meshes with the second rack 50 are connected by a connecting shaft 36. When the step motor 32 is driven and the first pinion 35 and the second pinion 37 rotate, the first rack 47 and the second rack 50 move in the same direction by the same distance. Thereby, the rendering device 20 can distribute the load due to the weight of the decorative body 31 to the first rack 47 and the second rack 50. As a result, it is possible to reduce the possibility of problems such as the inclination of the decorative body 31, the swinging of the moving decorative body 31, the deformation and breakage of the rack and pinion mechanism, and the deformation and breakage of the guide hole 44. Therefore, the rendering device 20 can execute a smooth rendering with a simple configuration using only one step motor 32.

  When the decorative body 31 moves to the origin position, the movement guide portion 42 of the decorative body 31 and the contact portion 53 of the middle frame 38 come into contact with each other. The magnet 55 of the movement guide part 42 and the magnet 54 of the contact part 53 are attracted, and the decorative body 31 is held at the origin position. Therefore, the rendering device 20 can reduce the possibility that the decorative body 31 is separated from the origin position when the rendering is not performed. Therefore, for example, even when the player hits or shakes the gaming machine, the rendering device 20 can firmly hold the decorative body 31 at the origin position.

  When the decorative body 31 moves to the end point position, the claw portion 60 of the second rack 50 contacts the contact portion 61 of the guide rail 51 from above. Therefore, the rendering device 20 can reliably prevent the two sets of rack and pinion mechanisms from being disengaged by the claw portion 60, and can stably perform the rendering. Since the lengths of the first rack 47 and the second rack 50 do not need to be excessively long for the purpose of preventing disengagement, the apparatus can be reduced in size.

  The moving direction of the decorative body 31 is the vertical direction, and the step motor 32 is arranged on the left side of the display device 10. Therefore, the decorative body 31 can be smoothly moved up and down by one step motor 32 without wasting a space in the center of the pachinko machine 1 where the display device 10 needs to be arranged. Furthermore, the rendering device 20 can reduce the load applied to the step motor 32 by the traction force of the tension spring 56 when the decorative body 31 is raised against gravity.

  In the rendering device 20, the first detected piece 66 detected by the origin sensor 63 and the second detected piece 67 detected by the end point sensor 64 are provided at positions separated from each other in the decorative body 31. . As a result, unlike the case where the origin sensor 63 and the end point sensor 64 detect the same detected piece, the degree of freedom of the arrangement positions of the origin sensor 63 and the end point sensor 64 can be increased. Therefore, the arrangement position of other members such as the flexible wiring 70 is not restricted, and the space can be used effectively.

  The step motor 32 in the present embodiment corresponds to the “motor” of the present invention. The magnet 55 corresponds to a “first magnet”, and the magnet 54 corresponds to a “second magnet”. The guide rail 51 corresponds to the “guide portion” of the present invention. The display device 10 corresponds to the “display unit” of the present invention. The contact portion 53 that holds the tension spring 56 corresponds to a “spring fixing portion”. The pachinko machine 1 corresponds to a “gaming machine”.

  The present invention is not limited to the embodiment described in detail above, and it is needless to say that various modifications can be made without departing from the gist of the present invention. First, a modification of the above embodiment will be described with reference to FIG. The rendering device 120 according to the modification is different from the rendering device 20 of the above-described embodiment only in that the rising assist rack 121 is used instead of the tension spring 56 (see FIG. 6) to assist the climbing of the decorative body 31. . Therefore, the same number is attached | subjected about the same structure and description is abbreviate | omitted.

  As shown in FIG. 11, the rendering device 120 according to the modified example includes an ascending auxiliary rack 121. The ascending auxiliary rack 121 extends in the vertical direction, and is supported by the middle frame 38 (see FIG. 4) so as to be movable in the vertical direction. The ascending auxiliary rack 121 has a tooth portion on the front surface (the right surface in FIG. 11). The opposite side of the first pinion 35 that engages with the first rack 47 meshes with the teeth of the ascending auxiliary rack 121. Since the ascending auxiliary rack 121 has a predetermined weight (for example, the same weight as that of the decorative body 31), a force in a direction in which the first rack 47 is raised is applied to the first pinion 35. Therefore, the rendering device 120 can reduce the load applied to the step motor 32 (see FIG. 5 and FIG. 6) by the ascending auxiliary rack 121. Further, unlike the case where the tension spring 56 is used, the force for assisting the raising of the first rack 47 does not change depending on the position of the decorative body 31, so that the decorative body 31 can be moved up and down in a stable state. it can.

  Other modifications can be made to the above embodiment. For example, in the above embodiment, the first rack 47 and the second rack 50 extend in the vertical direction, and the decorative body 31 moves in the vertical direction. However, the moving direction of the decorative body 31 is not limited to the vertical direction, and may be a horizontal direction, a front-rear direction, or an oblique direction. In the above embodiment, the origin position of the decorative body 31 is the upper end of the movement range. However, the lower end of the movement range or a position other than the upper end and the lower end may be set as the origin position of the decorative body 31.

  The rendering device 20 of the above embodiment includes the magnets 54 and 55 at the upper end of the movement guide portion 42 of the decorative body 31 and the contact portion 53 of the middle frame 38, thereby holding the decorative body 31 at the origin position. . However, the present invention can be realized even if one of the magnets of the movement guide part 42 and the contact part 53 is changed to a magnetic material such as iron. The same applies when the movement guide portion 42 itself or the contact portion 53 itself is formed of a magnetic material. Further, the position where the magnet is provided can be changed as long as the middle frame 38 and the decorative body 31 are in contact with each other.

  In the above embodiment, the claw portion 60 for preventing the rack and pinion mechanism from separating protrudes toward the front side. However, the direction in which the claw portion 60 protrudes may be a direction that intersects the extending direction of the first rack 47 and the second rack 50. The portion that comes into contact with the claw portion 60 when the decorative body 31 reaches the end point position is not limited to the guide rail 51. For example, another member for contacting the claw portion 60 may be formed on the middle frame 38 other than the guide rail 51. In the above embodiment, the power of the step motor 32 is transmitted to the first pinion 35 and the second pinion 37 via the gear 33. However, the structure for transmitting the power of the step motor 32 can also be changed. For example, the first pinion 35 may be directly fixed to the output shaft of the step motor 32.
