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, 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-described fraud is prevented by preventing the transmission member from rotating 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 an illegal act with respect to the opening and closing blades.

  However, in the variable prize winning device for gaming machines described in Patent Document 1, a bearing long hole for moving the rotation shaft and a guide groove for guiding the guide pin penetrate through both outer walls of the support member. Since it is formed in the form of a 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, when an external force is applied to the rotation shaft or the guide pin directly from the outside of the outer wall, the transmission member can be easily unlocked, thereby preventing an illegal act on the transmission member. It was not enough as composition yet.

  Patent Document 2 describes that a back cover that covers the lower part of the lever is provided in order to prevent an illegal act on the left and right levers (transmission members). According to Patent Document 2, although it is possible to prevent fraudulent acts on the lever by the back cover, it is insufficient as a configuration for preventing fraudulent acts on the left and right opening / closing bodies (rotating blade pieces).

An LED, a lamp, or the like can be used as the “light emitting means”.

  The standing wall can be provided with holding means for holding the cover body in a state having a gap corresponding to the thickness of the light emitting substrate in advance.

  As a result, the overall size does not change even if it is changed between the mounting form (first specification) and the non-mounting form (second specification) of the light emitting board, and no special structure for changing the specification is required. The variable winning device can be made small and compact, and the mounting structure for the gaming machine can be simplified.

  As a holding means provided on the standing wall, there is a leveling step corresponding to the thickness of the light emitting substrate so as to hold the gap between the locking claw for locking the cover body by elastic deformation and the cover body, and it protrudes at a two-step height And a protruding wall. By such a locking claw and a protruding wall, the holding means can be provided inexpensively and simply.

Each inner wall 65 is connected to the intermediate wall 64 so as to extend across the front and rear and the lower side of the intermediate wall 64.

  A fitting groove 65a for fitting the proximity switch 70 back and forth is formed inside the lower step of each inner wall 65. 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 64a for guiding the game ball to the cutout hole 67a of the support bottom wall 67 is formed on the front surface of the intermediate wall 64 (see FIG. 5B).

  At the front left and right positions of the ceiling wall 66, there are formed mounting portions 66c that fit into the mounting portions 16 of the base plate 10 and are fixed by screws 81 (fastening members) (see FIG. 4).

  As shown in FIG. 7, the cover body 80 and the light emitting substrate 90 are sandwiched between the rear end surface of the upright wall 18 of the base plate 10 and the front end surface of the intermediate wall 64 of the base body 60. The mounting portion 66c of the body 60 is fixed to the screw 81 (see FIGS. 3 and 4). As a result, the guide groove 17a2, the guide protrusion 57, the support shaft portion 65c, and the bearing portion 53 described above are covered from the outside by the cover body 80 (see FIG. 6B), thereby preventing external contact. . In addition, the standing wall 18 is provided at a total of three locations on the left and right sides of the bottom of the base plate 10, and a light emitting substrate 90 is disposed between the rear end surface of the standing wall 18 and the front end surface of the cover body 80. A plurality of (for example, five) LEDs 91 (light emitting means) for irradiating the base plate 10 with light are mounted on the light emitting substrate 90.

  More specifically, a plate-like locking claw 18a that locks the cover body 80 by elastic deformation is held on the standing wall 18 at the bottom, and a space between the cover body 80 is held on both sides of the locking claw 18a. For this purpose, there are provided first and second projecting walls 18b and 18c having a level difference corresponding to the thickness T of the light emitting substrate 90 and projecting in a plate shape at different heights. The locking claw 18a passes through the cutout portion 90a of the light emitting substrate 90 and the cutout portion 80a of the cover body 80 while being elastically deformed, and then the locking portion formed in the cutout portion 80a of the cover body 80 by elastic recovery. It is latched on 80a1. At this time, the rear end surface of the higher first projecting wall 18 b contacts the front end surface of the cover body 80, and the rear end surface of the lower second projecting wall 18 c contacts the front end surface of the light emitting substrate 90.

  The left and right standing walls 18 have first and second projecting walls 18b and 18c that have steps corresponding to the thickness T of the light emitting substrate 90 and project at different heights in order to maintain a distance from the cover body 80. Is provided. The higher first protruding wall 18 b protrudes in a cylindrical shape and passes through the through hole 90 b of the light emitting substrate 90, and its rear end surface abuts on the front end surface of the cover body 80. A columnar head 18b1 that is concentric with the first projecting wall 18b and has a smaller diameter than the first projecting wall 18b is formed on the rear end surface of the first projecting wall 18b. It is inserted into the insertion hole 80b formed in. On the other hand, the lower second protruding wall 18 c protrudes in a plate shape, and its rear end surface comes into contact with the front end surface of the light emitting substrate 90.

  Each standing wall 18 can hold the cover body 80 with a gap S (see FIG. 11) corresponding to the thickness T (see FIG. 6A) of the light emitting substrate 90 in advance. Accordingly, the light emitting substrate 90 is mounted between the rear end surface of the second projecting wall 18c and the front end surface of the cover body 80 (see FIG. 6A; the first specification winning device 5), and the second projecting surface. A non-mounting configuration in which the rear end surface of the wall 18c and the front end surface of the cover body 80 are disposed to face each other with a gap S corresponding to the thickness T of the light emitting substrate 90 (see FIGS. 11 to 13; second specification winning device) 5 '). In the mounting form (first specification), the light emitting substrate 90 and the cover body 80 are sandwiched between the rear end face of the second projecting wall 18c and the front end face of the cover body 80. In the non-mounting form (second specification), the cover The body 80 is sandwiched between the rear end surface of the first projecting wall 18 b and the front end surface of the cover body 80.

  Next, the operation of the winning device 5 configured as described above will be described with reference to FIGS. In FIG. 8B, FIG. 9B, and FIG. 10B, the front decorative member 20, the compression coil spring 44 of the solenoid 40, the cover body 80, the light emitting substrate 90, and the like are omitted.

  When the coil portion 41 of the solenoid 40 is maintained in the energization release state, as shown in FIG. 8A, each rotating blade piece 30 is in the closed position. In this state, as shown in FIG. 8 (b), the plunger 42 is in the operating position, and the rear end surface of the long hole 53a of the bearing portion 53 is in contact with the support shaft portion 65c in each arm portion 51, and the guide protrusion portion. 57 is engaged with the guide groove 17a2 of the guide portion 17a.

  When the coil portion 41 is energized, the plunger 42 at the original position shown in FIG. 8B moves toward the intermediate position shown in FIG. 9B. 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. If it will be in this state, the guide protrusion 57 will come off from the guide groove 17a2 of the guide part 17a.

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. 10B, 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 becomes the stopper rib 22 ( By abutting on (see FIG. 4), 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. 10 (b) receives the urging force of the compression coil spring 44 and the intermediate position shown in FIG. 9 (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. 9B, each rotating blade piece 30 also reaches the closed position.

  Next, the plunger 42 moves from the intermediate position shown in FIG. 9B 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. 8B and the rotating blade pieces 30 have reached the closed position, the rotating blade pieces 30 are forced to be moved 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.

  As described above, in this embodiment, the support shaft portions 65c that movably support the arm portions 51 are provided on the inner side walls 65 of the base body 60, and the arm portions 51 are engaged with the support shaft portions 65c. A bearing portion 53 having a hole 53a is provided. Further, a guide groove 17 a 2 that can be engaged with the guide projection 57 of each arm portion 51 is formed in the guide wall 17 of the base plate 10. Since the guide groove 17a2, the guide protrusion 57, the support shaft portion 65c, and the bearing portion 53 are covered from the outside by the cover body 80, contact from the outside is prevented. Therefore, an unauthorized act on the transmission member 50 can be prevented with a simple configuration in which only the cover body 80 is provided. In this way, a configuration for preventing an illegal act on the rotating blade piece 30 and a configuration for preventing an illegal act on the transmission member 50 can be compactly incorporated.

  Further, the first specification (deluxe type) for attaching the light emitting substrate 90 to shine the base plate 10 without changing the shape or structure of the base plate 10, the base body 60 or the cover body 80 and the light emitting substrate 90 were removed. The second specification (normal type) can be easily set, and versatility can be improved without deteriorating the function of preventing the above-described fraud.

  In addition, the overall size does not change even if the winning device 5 of the mounting form (first specification) of the light emitting substrate 90 is changed to the winning device 5 ′ of the non-wearing form (second specification), and the specification is changed. Therefore, the winning devices 5 and 5 ′ can be made small and compact, and the mounting structure for the pachinko machine 1 can be simplified.

  Further, in this embodiment, each support shaft portion 65 c is projected outwardly on the outer surface of each inner wall 65, and the game balls introduced into the base body 60 are located on both inner walls 65, 65. It is configured to 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 this 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 above 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 this embodiment, the solenoid 40 is used as the drive actuator, but other linear stepping motors and the like can be employed. Further, in addition to the pachinko machine 1, the invention can be applied to a ball game machine such as an alepachi machine.
