Description

  The present invention relates to a winning ball receptacle for a gaming machine, and more particularly to a fraud prevention mechanism for a winning ball receptacle provided with a pair of movable wing pieces that pivot and open.

  In a winning ball receiver that includes a pair of movable blades that are rotatably supported, there is one in which an opening / closing operation of the movable blade pieces is performed by an operation arm that is rotated forward and backward by an electromagnetic solenoid. In this case, a fraudulent act of forcibly opening the movable wing piece in a standing posture may be performed by a wire inserted from the front of the gaming machine.

Therefore, in order to prevent this, in Patent Document 1, a restraining piece is formed on a solenoid crank that is attached to the tip of a plunger of an electromagnetic solenoid and rotates a crank member (operation arm), and the base of the crank member is also described. When the notch is formed at the end, the plunger advances, the crank member rotates downward, and the movable wing piece is closed, the restraining piece fits into the notch and the crank member rotates upward. It regulates and prevents the opening of the movable wing piece.
Patent No. 3394229

  However, since the holding piece is integrated with the plunger in the conventional structure described in Patent Document 1, the holding piece and the notch are added to the plunger stroke in addition to the upward and downward turning strokes of the crank member. Strokes for fitting and removing the parts are required, so that the stroke length of the plunger becomes long, and the winning ball receiver extends in this direction, which is difficult to arrange to avoid interference with other members. There is a problem. Further, the crank member cannot be rotated upward until the fitting of the holding piece with the notch is completely eliminated, and there is a problem that the timing for starting to open the movable blade piece is delayed by that amount.

  SUMMARY OF THE INVENTION Accordingly, the present invention solves such a problem, and an object thereof is to provide a winning ball receiver for a gaming machine equipped with a fraud prevention mechanism capable of avoiding an increase in size in the plunger stroke direction. .

In order to achieve the above object, in the present invention, it is supported in a pivotable manner so that it can be turned into a standing posture that stands up and makes it difficult for the winning ball to enter, and a tilted posture that tilts and makes it easy to enter the winning ball. A movable blade piece (2A, 2B) to be moved, a drive means (4) having a linearly reciprocating plunger (42), and a pivotally supported, forward and reverse rotation according to the reciprocating motion of the plunger (42). The tip (311, 321) is moved to contact a part of the movable blade piece (2A, 2B), and is rotated forward with the one-way movement of the plunger (42) to move the movable blade piece (2A, 2B) ) To an upright posture, and an operation arm (3) for reversely rotating in accordance with the other direction movement of the plunger (42) to rotate the movable blades (2A, 2B) to a tilted posture, It is provided separately from the plunger (42) and moves relative only in the direction of movement of the plunger (42). A stopper member (6) that engages with the plunger (42) in a state where movement is restricted and moves integrally with the plunger (42), and a stopper member (6) in a direction crossing the moving direction of the plunger (42) The stopper member (6) is moved forward to the stopper position (143) in the intersecting direction along with the one-way movement of the plunger (42) and moved to the stopper position (143). (143) while restricting the reverse rotation of the operating arm (3) opposite rotational direction operation opposite thereto by an arm (3) at the stopper position with the other direction movement of the plunger (42) (143 ) Is retracted in the intersecting direction so that the operation arm (3) can be reversely rotated.

  In the present invention, since the stopper member separate from the plunger is provided, the upward rotation of the operation arm accompanying the forced opening of the movable wing piece can be surely restricted to prevent unauthorized actions. The stopper member can be moved to the stopper position simultaneously with the forward rotation of the operation arm due to the one-way movement of the plunger, and moved in the retracting direction simultaneously with the reverse rotation of the operation arm due to the other-direction movement of the plunger. Therefore, the stopper member can also be moved within the plunger stroke for rotating the operation arm. Therefore, since it is not necessary to make the plunger stroke longer than necessary, it is possible to avoid an increase in the size of the winning ball receiver in the stroke direction. In this case, since the operating arm is immediately rotated with the operation of the plunger, the opening / closing timing of the movable blade piece is not delayed. The stopper member can move from the uppermost horizontal position of the electromagnetic solenoid to the lowermost horizontal position of the operation arm, so that the stopper member is higher than conventional (for example, Japanese Patent Application Laid-Open No. 2003-033489). There is no need to expand in the vertical direction. Further, since the stopper member is separated from the plunger, the model that does not require the stopper member is not provided, and the structure of the winning ball receiver can be simplified.

  Here, the stopper member (6) engages with the plunger (42) in a state in which relative movement is restricted only in the movement direction of the plunger (42) and moves integrally therewith, while the plunger (42) )), A guide member (12) for moving and guiding the stopper member (6) in a direction intersecting the moving direction can be provided.

  The stopper member (7) is pivotally supported so that the stopper member (7) is advanced and rotated as the plunger (42) moves to reach the stopper position.

  In addition, the code | symbol in the said parenthesis shows the correspondence with the specific means as described in embodiment mentioned later.

  As described above, according to the winning ball receiver of the gaming machine of the present invention, even if a stopper member is added, the same dimensions can be maintained without changing the size of the winning ball receiver. The problem of having a hard time with the arrangement to avoid the interference is solved.

(First embodiment)
FIG. 1 shows a side view of the winning ball receiver, and FIG. 2 shows an exploded perspective view thereof. In each figure, the winning ball receiver includes a housing 1, and the housing 1 is composed of a front plate 11 attached to the game board and a guide wall 12 formed to protrude from the back surface of the front plate 11. An opening 13 is formed in the center of the front plate 11, and the guide wall 12 is formed so as to surround the opening 13. Movable wing pieces 2A and 2B (FIG. 2) are rotatably mounted on the pair of shaft bodies 21 (FIG. 1) protruding forward from the left and right positions of the front plate 11, respectively. The wing pieces 2A and 2B stand up and face each other to make it difficult for the winning ball to enter (the state shown in FIG. 2), and tilted to make the winning ball enter easily by tilting away from each other. (See FIG. 3). Here, in this embodiment, a stopper piece 22 that protrudes toward the front plate 11 and enters the opening 13 is formed at the lower end of each movable wing piece 2A, 2B. A cover plate 81 is provided in front of the movable blade pieces 2A and 2B.

  The operation arm 3 is accommodated in the guide wall 12. The operation arm 3 is formed in a substantially U shape in plan view, and a shaft portion 33 formed to project from the base end side surfaces of the left and right arm portions 31 and 32 is provided at the lower end portions of the left and right side walls of the guide wall 12. It is inserted into the hole 121 so as to be rotatable, and can be rotated in the vertical direction. The left and right arm portions 31 and 32 of the operation arm 3 have their tips 311 and 321 extending through the opening 13 to the lower end portions of the movable blade pieces 2A and 2B, respectively, and abutting on a part thereof. When rotating, the movable blade pieces 2A and 2B are rotated to a standing posture (FIG. 1), and when the operating arm 3 is rotated upward, the movable blade pieces 2A and 2B are rotated to a tilted posture (see FIG. 3). ). The stopper pieces 22 of the movable wing pieces 2A and 2B in the standing posture are in contact with the outer side surfaces of the arm portion tips 311 and 321 of the operation arm 3 rotated downward. An operation piece 34 extends upward from the arm portions 31 and 32 of the operation arm 3.

  An electromagnetic solenoid 4 is positioned above the operation arm 3, and the electromagnetic solenoid 4 is fixed to the upper half rear end surface of the guide wall 12. A plunger 42 protrudes into the guide wall 12 from the front center of the casing 41 of the electromagnetic solenoid 4, and the tip 421 of the plunger 42 has a large-diameter disk shape. A sandwiching piece 5 formed in a cylindrical shape is fitted on the outer periphery of the plunger 42, and a stopper member 6, which will be described in detail later, is located between the sandwiching piece 5 and the plunger tip 421. A coil spring 43 (FIG. 2) is disposed on the outer periphery of the plunger 42 between the clamping piece 5 and the front surface of the casing 41 of the electromagnetic solenoid 4, and the extension spring force causes the plunger 42 to protrude through the clamping piece 5. Is energized. When the electromagnetic solenoid 4 is energized and energized, the plunger 42 is retracted toward the front surface of the casing 41 against the spring force of the coil spring 43.

  The stopper member 6 is formed in a gate shape having left and right stopper portions 61 and 62 extending downward, and the lower ends of the stopper portions 61 and 62 are positioned above the left and right arm portions 31 and 32 of the operation arm 3. The arm portions 31 and 32 are opposed to each other. In the stopper member 6, the plate surface of the connecting portion 63 that connects the left and right stopper portions 61, 62 is sandwiched between the plunger tip portion 421 and the sandwiching piece 5, whereby the stopper member 6 is relative to the movement direction of the plunger 42. The movement is restricted, and relative movement is possible upwards perpendicular to the plunger movement direction. Pin portions 64 project from the upper side surfaces of the left and right stopper portions 61 and 62 of the stopper member 6, and the pin portions 64 are formed in the guide grooves 14 formed in the upper half portions of the left and right side walls of the guide wall 12. It is located so as to be movable along this.

  The guide groove 14 is formed by cutting a part of the side wall of the guide wall 12 into a line having a constant width, and extends horizontally forward from the rear end surface of the guide wall 12 (hereinafter referred to as the upper end horizontal portion 141). It extends diagonally forward and downward (hereinafter referred to as an inclined portion 142), and further extends forward in the horizontal direction (hereinafter referred to as a lower end horizontal portion 143). When the electromagnetic solenoid 4 is in a non-excited state and the plunger 42 is projected by the spring force of the coil spring 43, the pin portion 64 of the stopper portions 61 and 62 is located at the lower end horizontal portion 143 (stopper position) of the guide groove 14, As described above, the lower ends of the stopper portions 61 and 62 are opposed to the upper portions of the operation arm 3 that are slightly separated from the arm portions 31 and 32. The upper end of the operation piece 34 extending from each arm portion 31, 32 of the operation arm 3 is located between the rear surface of the connecting portion 63 of the stopper member 6 and the clamping piece 5, and the operation piece is in the state where the plunger 42 protrudes. The operation arm 3 is rotated downward (forward rotation) via 34 to rotate the movable blade pieces 2A and 2B to the upright posture as shown in FIG.

  In the winning ball receiver having such a structure, the movable blade pieces 2A and 2B in the standing posture are provided at the lower ends of the movable blade pieces 2A and 2B even if the movable blade pieces 2A and 2B are forced to tilt from the outside without using the plunger 42. Since the stopper pieces 22 are in contact with the outer surfaces of the arm portion tips 311 and 321 of the operation arm 3, the tilting of the movable blade pieces 2A and 2B in a direction away from each other is restricted. When the movable wing pieces 2A and 2B are tilted with a stronger forcible force, the arm portions 31 and 32 of the operation arm 3 are pushed upward, and the clamping piece 5 is slightly retracted by the operation piece 34, but the plunger tip 421 In order to maintain the position of the connecting portion 63 of the stopper member 6, the stopper portion 61 is in contact with the lower ends of the stopper portions 61 and 62 of the stopper member 6 positioned immediately above, and further upward rotation (reverse rotation) is prevented. . The stopper piece 22 prevents the movable wing pieces 2 </ b> A and 2 </ b> B itself from being illegally or erroneously tilted due to the impact of the game ball, and the stopper member 6 prevents the operation arm 3 from being reversely rotated by unauthorized action. Thus, by providing the crime prevention mechanism having different properties in a superimposed manner, a safer winning ball receiver can be obtained.

  When opening the movable blades 2A and 2B, the electromagnetic solenoid 4 is energized and excited, and the plunger 42 is moved backward toward the front surface of the casing 41 against the spring force of the coil spring 43. Accordingly, the operation arm 3 is rotated upward via the operation piece 34, and the movable blade pieces 2A and 2B are tilted in directions away from each other by the tips 311 and 321 of the arm portions 31 and 32. It becomes a posture (FIG. 3). At this time, the stopper member 6 retreats integrally with the plunger 42 as it starts retreating. At the same time, the pin portion 64 of the guide groove 14 extends horizontally from the lower end horizontal portion 143 to the upper end horizontal portion 143. The stopper member 3 as a whole moves rearward and upward to reach the retracted position. As described above, since the stopper portions 61 and 62 of the stopper member 6 also move upward along with the upward rotation of the arm portions 31 and 32 of the operation arm 3, the upward rotation of the arm portions 31 and 32 is prevented. Absent.

  When the movable blade pieces 2A and 2B are operated upright again, the energization of the electromagnetic solenoid 4 is canceled to de-energize it. The plunger 42 advances toward the front plate 11 by the spring force of the coil spring 43, and accordingly, the operation arm 3 is rotated downward via the operation piece 34, and the distal ends 311, 321 of the arm portions 31, 32. As a result, the movable wing pieces 2A and 2B are erected so as to face each other and assume an upright posture (FIG. 1). At this time, the stopper member 6 moves obliquely forward along the guide groove 14 together with the plunger 42 as the plunger 42 starts moving forward, and reaches the stopper position 143.

  In the present embodiment, by providing the stopper member 6 separate from the plunger 42, the upward rotation of the operation arm 3 associated with the forced tilting of the movable blade pieces 2A and 2B is surely restricted to prevent unauthorized actions. can do. The stopper member 6 is moved from the stopper position 143 to the upper retracted position 141 simultaneously with the upward rotation of the operation arm 3 due to the backward movement of the plunger 42, and at the same time the downward rotation of the operation arm 3 due to the forward movement of the plunger 42. Simultaneously with the movement, the stopper member 6 is moved from the retracted position 141 to the stopper position 143 below, so that the stopper member 6 can also be moved within the plunger stroke for rotating the operation arm 3. Therefore, it is not necessary to make the plunger stroke longer than necessary, and an increase in the size of the winning ball receiver in the stroke direction can be avoided. Moreover, in this embodiment, since the stopper member 6 is moved in the direction crossing the moving direction of the plunger 42, this also prevents an increase in the size of the winning ball receiver in the stroke direction. Furthermore, since the stopper member 6 is separated from the plunger 42, it is possible to flexibly change whether or not the winning ball receiver has a fraud prevention function according to the user's needs. In addition, even if it does not provide the stopper piece 22 of movable blade piece 2A, 2B in this embodiment, sufficient crime prevention function can be exhibited compared with the conventional winning ball receiver. On the other hand, even if the stopper member 62 is not provided and the stopper piece 22 alone is provided, a sufficient crime prevention function can be exhibited as compared with the conventional winning ball receiver. Moreover, based on the internal structure demonstrated by this embodiment, it is also possible to make only one of movable blade pieces.

(Second Embodiment)
In the present embodiment, as shown in FIG. 4, guide grooves 15 having substantially the same shape are further formed in parallel below the guide grooves 14 on the side walls of the guide walls 12 in the first embodiment. Then, a new pin portion 65 is projected from the middle portion in the vertical direction of the stopper portions 61 and 62 of the stopper member 6 and is positioned so as to be movable along the guide groove 15. Other structures are the same as those in the first embodiment. According to such a structure, the same effect as that of the first embodiment can be obtained, and the stopper member 6 is always reliably held in the upright posture by the upper and lower pin portions 64, 65. The action is more reliably performed. FIG. 5 shows a state in which the operating arm 3 is rotated upward, the movable blade pieces 2A and 2B are tilted, and the stopper member 6 has reached the upper retracted position.

( Reference example )
In this reference example , as shown in FIG. 6, the stopper member 7 has arm-like stopper portions 72 that are bent in a substantially L shape on both sides via connecting portions 71. A shaft portion 73 protruding from the side surface of the bent portion of the portion 72 is rotatably supported by a support piece 44 provided on the front surface of the casing 41 of the electromagnetic solenoid 4. The connecting portion 71 of the stopper member 7 is located between the tip portion 421 of the plunger 42 and the sandwiching piece 5, the excitation of the electromagnetic solenoid 4 is canceled, and the plunger 42 is advanced by the spring force of the coil spring 43 (see FIG. 2). In the state shown in FIG. 6, the tip 723 of the lower arm 722 extending downward at a substantially right angle with respect to the upper arm 721 is at an upper stopper position near the arm portions 31 and 32 of the operation arm 3, and moves forward. It faces the arm portions 31, 32 that are inclined downward. The distal end 723 of the lower arm 722 is formed in a wedge shape, and the distal end side surface 7 a inclined rearward and downward is opposed to the protruding portion 35 formed on the upper surfaces of the arm portions 31 and 32 of the operation arm 3. The upper end of the operation piece 34 of the operation arm 3 is located between the plunger tip 421 and the sandwiching piece 5. Other structures are the same as those in the first embodiment.

  In the state of FIG. 6 where the movable blade pieces 2A and 2B are in the standing posture, when the movable blade pieces 2A and 2B are forced to stand up, the leg portions 31 and 32 of the operation arm 3 are pushed upward. The protruding portion 35 of the arm portions 31 and 32 comes into contact with the side surface 7a of the lower arm tip 723 of the stopper member 7 located immediately above, and tries to rotate the stopper member clockwise in FIG. However, since the stopper member 7 with the connecting portion 71 locked to the plunger 42 is restricted from further clockwise rotation, the upward rotation of the arm portions 31 and 32 of the operation arm 3 is prevented. . Thereby, the forced tilting of the movable blade pieces 2A and 2B is reliably prevented.

When the movable blade pieces 2A and 2B are opened, the electromagnetic solenoid 4 is energized and excited, and the plunger 42 is moved back toward the front surface of the casing 41 against the spring force of the coil spring 43. Accordingly, the operation arm 3 is rotated upward via the operation piece 34, and the movable blade pieces 2A and 2B are tilted in directions away from each other by the tips 311 and 321 of the arm portions 31 and 32. It becomes a posture (FIG. 7). At this time, the stopper member 7 is rotated counterclockwise in FIG. 6 as the plunger 42 starts to retract, and the tip 723 of the lower arm 722 moves to the upper retracted position (FIG. 7). As described above, since the lower arm 722 of the stopper member 7 also pivots upward with the upward rotation of the arm portions 31 and 32 of the operation arm 3, the upward rotation of the arm portions 31 and 32 is prevented. There is no. Even by the present embodiment, the same effect as the first embodiment can be obtained.
