Description

  The present invention relates to a variable winning device for a gaming machine used for a start winning opening of a pachinko machine and a gaming machine such as a pachinko machine provided with the variable winning device for the gaming machine.

  A variable prize device for a gaming machine is a drive actuator (for example, a pair of rotary wing pieces that open and close between a closed position where a game ball is difficult to enter and an open position where a game ball is easy to enter, and a plunger that can move linearly. , Solenoid) and a transmission member for transmitting the driving force of the solenoid to the rotating blade piece while converting the linear movement of the plunger into the rotating movement of the rotating blade piece. As a variable prize device for this type of gaming machine, for example, in Patent Document 1 below, a wire or the like is inserted through a gap in a pachinko machine, and an open / close blade (rotary blade piece) that is closed by the wire or the like is forcibly used. Even when an external force is applied so as to be opened, the above-mentioned fraudulent act is prevented by preventing the rotation of the transmission member by a mechanical lock. Specifically, the transmission member is composed of a pair of linkage arms and a linkage arm that couples the linkage arms, each linkage arm having a rotation shaft that protrudes outward, and the linkage arms are outward. A guide pin is provided. On both outer walls of the support member (base body) attached to the rear side of the base plate, bearing elongated holes are formed for supporting the pivot shafts of the linkage arms so as to be pivotable and movable in the front-rear direction. A guide groove for guiding the guide pin of the connecting arm is also formed. The guide groove is formed with a linear groove portion (rotation restricting portion) extending forward. When the open / close blades are in the closed position corresponding to the protruding position of the plunger, the pivot shaft of each linkage arm is located at the front end of the bearing long hole, and the guide pin of the connecting arm is located in the straight groove portion of the guide groove. It is supposed to be located in. When an external force that forcibly opens the open / close blade in the closed state is applied, the guide pin is prevented from moving upward by the linear groove portion, so that the rotation of the transmission member is restricted (locked). Thus, the closed state of the open / close blades is maintained. For this reason, it is possible to prevent the above-described fraud.

JP 2008-272121 A

  However, in the variable prize device for gaming machine described in the above-mentioned Patent Document 1, the bearing long hole for moving the rotation shaft and the guide groove for guiding the guide pin penetrate the both outer walls of the support member. Since it is formed in the form of a through hole, it is possible to directly touch the rotating shaft in the bearing long hole and the guide pin in the guide groove through the outer wall. For this reason, if an external force that directly moves backward from the outside of the outer wall is applied to the rotation shaft or guide pin, the transmission member can be easily unlocked. It was still not enough.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a variable prize device for a gaming machine that can satisfactorily prevent fraud.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the variable prize winning device for gaming machines of the present invention is:

Engaged and held in the guide groove,
The support shaft portion and the bearing portion are disposed at an inner position than the outer wall formed outside the inner wall of the base body, and the guide groove and the guide protrusion are formed outside the guide wall of the base plate. The support shaft portion, the bearing portion, the guide groove, and the guide projection are surrounded by the outer wall of the base body and the outer wall of the base plate , In contrast, contact from the outside is prohibited.

  In this variable award winning device for gaming machines, a support shaft portion that movably supports the transmission member is provided on the base body, and a bearing portion having a long hole that engages with the support shaft portion is provided on the transmission member. The base plate is provided with a guide wall having a guide groove for restricting the rotation of the transmission member, and the transmission member is provided with a guide protrusion that can be engaged with the guide groove. And a support shaft part and a bearing part are arrange | positioned in the inner position rather than the outer side wall of a base body, and the guide groove and guide protrusion are arrange | positioned in the inner position rather than the outer side wall of a base plate. That is, unlike the conventional variable prize device for gaming machines, a long bearing hole for moving the rotation shaft of the transmission member to the outer wall of the base body and a penetration hole for guiding the guide pin of the transmission member are provided. There is no need to form a guide groove. This makes it impossible to directly touch any of the support shaft, bearing, guide groove, and guide protrusion from the outside, and it is impossible to apply any external force that directly moves the transmission member.

  Each outer wall 15 is formed with an opening 15a that is open to the side by cutting out the substantially upper half of the rear side so that the base plate 10 and the base body 60 can be slidably engaged back and forth. ing. By forming the opening 15a, each outer wall 15 has a stepped shape in a side view. An inner wall 17 is integrally formed at an inner position separated from each outer wall 15 by a predetermined distance. The upper end of the inner wall 17 is connected to the ceiling wall 13, the lower end is connected to the bottom wall 14, and the front end is connected to the front portion of the base plate 10. The inner wall 17 is cut off from the lateral exterior by the outer wall 15 so that almost all of the rear edge is not visible from the opening 15a in a side view. The inner wall 17 functions as a reinforcing member, and a part of the inner wall 17 is cut into a predetermined shape to serve as a guide wall for guiding a guide protrusion 57 of each arm portion 51 described later.

  The front decoration member 20 includes an inclined portion 21 for holding each rotating blade piece 30 to be described later in a closed position and a stopper rib 22 for holding the rotary blade piece 30 in an open position. It is attached to the front part of the base plate 10 by this. In addition, in order to smoothly guide the winning game ball backward, a guide rib 23 is integrally formed on the front decorative member 20 (see FIGS. 4 and 5B).

  Each rotary wing piece 30 is supported by a support pin 31 laid back and forth across the base plate 10 and the front decorative member 20 so as to be rotatable around an axis O1 (first axis). Each rotary blade 30 includes an engagement protrusion 32 that extends to the rear of the base plate 10 through the passage hole 10a of the base plate 10 at a portion inside the support pin 31, and has a front decoration at a lower portion. Each rotating blade piece 30 is held in the closed position by abutting against the inclined portion 21 of the member 20, and a positioning piece 33 is provided for holding each rotating blade piece 30 in the open position by contacting the stopper rib 22.

  The engaging protrusion 32 of each rotating blade piece 30 functions as an operated portion of the rotating blade piece 30 that receives an action from the transmission member 50. That is, when a downward force is applied from the transmission member 50 to the engaging protrusion 32, the rotating blade pieces 30 are urged in the direction (inward) approaching each other around the axis O1 (FIG. 5 ( b)), when an upward force is applied, the rotating blade pieces 30 are biased in the direction (outward) away from each other around the axis O1 (see FIG. 7B).

  As shown in FIG. 4, the solenoid 40 (drive actuator) includes a coil part 41, a plunger 42, and a metal case 43 that surrounds the left and right front and rear sides of the coil part 41, and is generated by energizing the coil part 41. The plunger 42 is moved back and forth by the electromagnetic force.

  Specifically, a pair of front and rear disk-shaped flange portions 42 a and 42 a (acting portion of the plunger) are provided at the front end portion of the plunger 42, and compression is performed between the rear flange portion 42 a and the case 43. A coil spring 44 is interposed, and the plunger 42 is pulled into the coil portion 41 while compressing the compression coil spring 44. That is, the plunger 42 is in the original position (forward position, protruding position) pushed forward by the urging force of the compression coil spring 44 when the coil portion 41 is deenergized, and the compression coil spring 44 when the coil portion 41 is energized. It moves to the operating position (retracted position) drawn into the coil portion 41 against the urging force.

  As shown in FIGS. 4 to 8, the transmission member 50 is formed by integrally forming a pair of arm portions 51, 51 by a bridging portion 52. At the rear lower position of the outer surface of each arm portion 51, it engages with a support shaft portion 65 c of the inner wall 65 described later, and each arm portion 51 can be moved in the operation direction (front-rear direction) of the plunger. A bearing portion 53 having a long hole 53a that allows the arm portion 51 to turn around the support shaft portion 65c as a rotation center extends backward. A part of the portion overlapping the bearing portion 53 is cut out at the rear portion of each arm portion 51 to form a recess 54 so that the inner wall 65 does not come into contact with each arm portion 51 when moving backward ( The inner wall 65 is avoided).

  At the front end of each arm portion 51, a bifurcated action portion 55 that can engage with the engaging protrusion 32 of the rotating blade piece 30 is provided to protrude forward. An engaging projection 56 (acting portion) that engages with a groove 42b formed between the flange portions 42a and 42a of the plunger 42 is provided inwardly at a position above the rear portion of the inner surface of each arm portion 51. ing.

  A round shaft-shaped guide protrusion 57 that is guided by the guide portion 17 a of the inner wall 17 of the base plate 10 is provided outwardly at a position above the center of the outer surface of each arm portion 51. Further, the position of each arm portion 51 in the left-right direction is shifted to the position above the front portion of the outer surface of each arm portion 51 by contacting the inner surface of the inner wall 17 of the base plate 10 when each arm portion 51 moves. A hemispherical protrusion 58 is provided to protrude outward (see FIG. 4).

  As shown in FIG. 4, the base body 60 includes an upper accommodating portion 61 that accommodates the case 43 of the solenoid 40, and a lower accommodating portion that accommodates the transmission member 50 and the proximity switch 70 in cooperation with the base plate 10. 62. The solenoid 40 is incorporated into the housing portion 61 from the rear of the base body 60 and is fixedly disposed in the housing portion 61 with a screw 83.

  The accommodating part 62 is integrally provided with a pair of left and right outer walls 63, 63, an intermediate wall 64, and a ceiling wall 66. The intermediate wall 64 extends to the left and right so as to divide the housing portion 61 and the housing portion 62 in the front-rear direction, and is connected to the rear end of each outer wall 63. Each outer wall 63 is formed in a two-stepped shape so that the inner width of the lower step portion is wider than the upper step portion, and the lower step portion is slidably engaged with the outer wall 15 of the base plate 10 in the front-rear direction. An opening 63a that is open to the side is formed by cutting out substantially the lower half of each. By forming the opening 63a, each outer wall 63 and intermediate wall 64 can come into contact with each outer wall 15 of the base plate 10 without a gap as shown in FIGS.

  A pair of inner side walls 65, 65 are integrally formed at an inner position separated from each outer wall 63 by a predetermined distance. Each inner wall 65 is connected to the intermediate wall 64 so as to extend in front of and behind the intermediate wall 64 and below. The front part of each inner wall 65 having the intermediate wall 64 as the base end can be seen from the side of each outer wall 63 by forming the opening 63a, and the upper step part is more base than the lower step part in a side view. It is formed in a two-stepped shape so that the protruding length from the end is short.

  A fitting groove 65a for fitting the proximity switch 70 back and forth is formed inside the lower step of each inner wall 65. Further, a locking claw 65b is formed at the rear end of the lower step portion of the one inner wall 65 to be locked and positioned at the rear end of the proximity switch 70 fitted in the insertion groove 65a. The lower steps of each inner wall 65 are connected to each other by a support bottom wall 67. The support bottom wall 67 functions as a reinforcing member on which the proximity switch 70 is placed, and a notch hole 67a for discharging the game ball that has passed through the proximity switch 70 downward is formed in the front portion thereof. (See FIG. 5B).

  On the outer side of the upper step portion of each inner wall 65, a round shaft-like support shaft portion 65 c that projects into the elongated hole 53 a of the bearing portion 53 in each arm portion 51 protrudes outward. Each support shaft 65c protrudes in the direction of the axis O2 (second axis) perpendicular to the axis O1. In a state in which each arm portion 51 is attached to the support shaft portion 65 c of each inner wall 65 by the long hole 53 a of the bearing portion 53, the inner side surface of each arm portion 51 is substantially on the same vertical plane as the inner side surface of each inner wall 65. Or the inner side surface of each arm portion 51 is set to be slightly outside the inner side surface of each inner wall 65.

  As a result, the game ball guided from the lower winning opening 12 to the inside of the base body 60 through the bowl 14a comes into contact with the inner side surface of the upper step portion of each inner wall 65 and enters the cutout hole 67a in the support bottom wall 67. Although it is guided, it hardly touches each arm portion 51. A guide rib 64 a for guiding the game ball to the cutout hole 67 a of the support bottom wall 67 is formed on the front surface of the intermediate wall 64.

  A mounting portion 63 b that fits with the mounting portion 16 of the base plate 10 is formed at a position above the front portion of each outer wall 63. The upper surface (outer surface) of the ceiling wall 66 is formed in an inclined surface shape whose height continuously decreases as it goes to the right, for example, and the game ball from the bowl 13a of the base plate 10 is placed outside the base body 60. It functions as a guide path for guiding to a predetermined position. The ceiling wall 66 is provided with a fall prevention wall 66a that prevents the game ball from falling, and the fall prevention wall 66a is provided with a guide rib 66b that guides the game ball to the right, for example.

  As shown in FIGS. 5 (c) and 9 (a), the guide portion 17a of each inner wall 17 in the base plate 10 has a height position that decreases toward the front along an arc having a predetermined curvature. And a rectangular guide groove 17a2 extending forward from the front end of the guide surface 17a1. The groove width of the guide groove 17a2 is set to be slightly larger than the diameter of the guide protrusion 57 of each arm portion 51. As shown in FIG. 9B, the guide surface 17a1 has a planar cross section.

  Next, the operation of the winning device 5 configured as described above will be described with reference to FIGS. In FIG. 5B, FIG. 6B, and FIG. 7B, the compression coil spring 44 of the solenoid 40 is omitted.

  When the coil portion 41 of the solenoid 40 is maintained in the energization release state, as shown in FIG. 5A, each rotating blade piece 30 is in the closed position. In this state, as shown in FIG. 5 (b), the plunger 42 is in the operating position, and as shown in FIG. 5 (c), the rear end surface of the long hole 53a of the bearing 53 in each arm portion 51 is the support shaft. The guide protrusion 57 is engaged with the guide groove 17a2 of the guide portion 17a while being in contact with the portion 65c.

  When the coil unit 41 is energized, the plunger 42 at the original position shown in FIG. 5B moves toward the intermediate position shown in FIG. 6B. Specifically, as the plunger 42 moves rearward, each arm portion 51 remains in the same posture, that is, with each rotary blade piece 30 held in the closed position, the front end of the long hole 53a of the bearing portion 53. The surface linearly moves backward until the surface comes into contact with the support shaft portion 65c. In this state, as shown in FIG. 6C, the guide protrusion 57 comes off from the guide groove 17a2 of the guide portion 17a.

  As the plunger 42 that has reached the intermediate position shown in FIG. 6B moves toward the working position shown in FIG. 7B, each arm 51 rotates about the axis O2 with the support shaft 65c as the center of rotation. Turn upward. At this time, the action part 55 of each arm part 51 pushes up the engaging protrusion 32 of the rotating blade piece 30 and rotates the rotating blade pieces 30 in directions away from each other around the axis O1.

  When the plunger 42 reaches the operating position shown in FIG. 7B, each rotating blade piece 30 further rotates by an extremely small amount around the axis O <b> 1 due to its own weight, and the positioning piece 33 is moved to the stopper rib 22 of the front decorative member 20. By contacting, it is held at the open position shown in FIG.

  On the other hand, when the coil portion 41 in the energized state is deenergized, the plunger 42 in the operating position shown in FIG. 7 (b) receives the urging force of the compression coil spring 44 and the intermediate position shown in FIG. 6 (b). Move towards Specifically, first, as the plunger 42 moves forward, each arm portion 51 pivots downward about the axis O2 with the support shaft portion 65c as a rotation center, and the elongated hole 53a of the bearing portion 53 is moved to the plunger 42. It is rotated until it is almost parallel to the operation direction (front-rear direction). When each arm portion 51 pivots downward, the action portion 55 pushes down the engaging protrusion 32 of the pivot blade piece 30 and pivots the pivot blade pieces 30 toward each other around the axis O1. In addition, the guide protrusion 57 is guided downward by the guide surface 17 a 1 of the guide portion 17. When the plunger 42 reaches the intermediate position shown in FIG. 6B, each rotating blade piece 30 also reaches the closed position.

  Next, the plunger 42 moves from the intermediate position shown in FIG. 6B toward the original position shown in FIG. In this case, each arm 51 moves straight forward until the rear end surface of the long hole 53a of the bearing 53 abuts on the support shaft 65c while maintaining the posture. When each arm part 51 moves forward, the guide protrusion 57 engages with the guide groove 17a2 of the guide part 17a and is guided forward. When the rear end surface of the long hole 53a of the bearing portion 53 comes into contact with the support shaft portion 65c, the guide protrusion 57 is positioned in the guide groove 17a2.

  In the state where the plunger 42 has moved to the original position shown in FIG. 5B and the rotating blade pieces 30 have reached the closed position, the rotating blade pieces 30 are forced to move to the open position by improper action. When an external force is applied, the guide protrusion 57 is prevented from moving upward by the guide groove 17a2, so that each arm portion 51 rotates upward about the axis O2 with the support shaft portion 65c as a rotation center. It is blocked (locked). Thereby, since the closed state of each rotating blade piece 30 is maintained, an illegal act can be prevented.

  By the way, in the first embodiment, each inner wall 65 of the base body 60 is provided with a support shaft portion 65c that movably supports each arm portion 51, and each arm portion 51 has a long hole that engages with the support shaft portion 65c. A bearing 53 having 53a is provided. Further, a guide groove 17 a 2 that can be engaged with the guide protrusion 57 of each arm portion 51 is formed on the inner wall 17 of the base plate 10. The support shaft portion 65c of each inner wall 65 and the bearing portion 53 of each arm portion 51 are disposed at an inner position than the outer wall 63 of the base body 60, and the guide groove 17a2 of each inner wall 17 and each arm portion 51. The guide protrusion 57 is arranged at an inner position than the outer wall 15 of the base plate 10.

  Thereby, it becomes impossible to directly touch any of the support shaft portion 65c of each inner wall 65, the guide groove 17a2 of each inner wall 17, the bearing portion 53 of each arm portion 51, and the guide protrusion 57 from the outside. Since it becomes impossible to apply any external force that directly moves each arm part 51, it is possible to prevent illegal acts well.

  Further, in the first embodiment, each support shaft portion 65c is projected outward from the outer surface of each inner wall 65, and the game balls introduced into the base body 60 are both inner walls 65, 65. It is comprised so that it may pass between. Thereby, even when the game ball gives an impact to each inner wall 65, the load due to the impact of the game ball does not act on each support shaft portion 65c and the bearing portion 53 of each arm portion 51, and each arm Smooth movement of the part 51 can be ensured.

  In the first embodiment, a proximity switch 70 for detecting the passage of a game ball introduced into the base body 60 is attached to both inner side walls 65, 65. As a result, each inner wall 65 has a function of preventing the fraudulent act and a function of ensuring the movement of each arm 51, and also has a function of accommodating the proximity switch 70. Therefore, the base body 60 can be formed compactly.

  In the first embodiment, the winning device 5 described above is fixedly arranged on the game board 2. Thereby, fraudulent acts can be effectively prevented, and the arrangement space for the other objects in the game board 2 can be secured satisfactorily.

  In the first embodiment described above, as shown in FIG. 9, the guide surface 17a1 of the guide portion 17a in each inner wall 17 is formed to have an arcuate shape in a side view and to have a planar cross section. However, instead of this, for example, as shown in FIG. 10, the guide surface 17a1 ′ of the guide portion 17a ′ in each inner wall 17 ′ is inclined linearly in side view and has an R-plane cross section. You may form in. Since the guide surface 17a1 ′ is formed in an R shape, the contact resistance with the guide protrusion 57 of each arm portion 51 can be reduced. Therefore, the guide according to the second embodiment is the same as in the first embodiment. The protrusion 57 can be smoothly guided along the guide surface 17a1 ′.
