The solenoid is provided with a return coil spring that urges the plunger forward, and the solenoid is excited so that the plunger moves backward against the elasticity of the return coil spring. Further, a substantially L-shaped crank member having a bifurcated portion extending forward and an engaging portion extending upward is pivotally supported in the machine frame so that it can be repeatedly rotated. The engagement with the bifurcated portion The hook is loosely fitted and the engagement pin is moved up and down by the bifurcated portion so that the opening / closing blade opens and closes, and when the plunger moves backward, the flange member provided at the tip of the plunger The engagement portion can come into contact with the back surface, and when the plunger moves forward due to the elasticity of the return coil spring, the hook member reaches the top of the bifurcated portion. The upward movement is prevented by the flange member.

  In this electric variable prize-winning device, when the solenoid is in a non-excited state and the plunger is kept in the advanced state by the return coil spring, the opening / closing blade is forced to open at the tip of the plunger. The opening and closing blades are prevented from opening by the provided saddle member, and the act of illegally winning the game ball is prevented in advance.

  Next, embodiments of the present invention will be described with reference to the drawings. 1 is a front view of the electric variable prize-winning device, FIG. 2 is a plan view, FIG. 3 is a perspective view from the rear, and FIG. 4 is a longitudinal sectional view. FIG. 5 is an exploded perspective view thereof. In these drawings, reference numeral 1 is a mounting board having a ball opening 2 in the center, 3 is a ball receiving member fixed by screws 4 on the front surface of the mounting board, and 5a and 5b are front faces of the mounting board 1. A pair of opening and closing blades pivotally supported by supporting shafts 6a and 6b provided in the ball receiving member so as to be able to stand upright and reversely in an octagonal manner, and the pachinko that has flowed into the back surface of the mounting substrate 1 from the entrance 2 A slowly and backwardly inclined sphere guide rod 7 for guiding the sphere backward is provided. Engagement pins 9 a and 9 b are integrally formed on the back surfaces of the opening and closing blades 5 a and 5 b, and the engagement pins protrude from the back surface of the mounting substrate 1. Reference numeral 10 denotes an ordinary winning opening formed on the top of the mounting substrate 1. Further, 1a and 1b are through-holes for passing through screws provided in the mounting board for attaching the mounting board 1 to the front surface of the game board 32 shown in FIG. 4, and 1c and 1d are rear ends of the support shafts 6a and 6b. It is a bearing part formed in the front surface of the attachment board | substrate 1 so that a part may be penetrated and fixed. In addition, 11 is a small hole formed in the center part of the attachment board | substrate 1 at penetration shape. A machine frame 12 is integrally formed on the back surface of the mounting substrate 1, and the ball guide rod 7 is formed at the lower center of the machine frame 12. In addition, a ball guide path 14 that is continuous with the rear surface of the normal winning opening 10 is formed integrally with the upper portion of the machine frame 12.

  On the rear side of the machine casing 12, a second machine casing 16 having a space for accommodating the solenoid 15 in a lateral direction is fixed by screws 17. 18 is a plunger of the solenoid 15, 19 is a return coil spring mounted on the outer periphery of the plunger, and the coil spring is compressed between the front surface of the solenoid 15 and the flange member 20 provided at the tip of the plunger 18. Provided. Therefore, by actuating the solenoid 15, the plunger 18 moves back and forth in the horizontal direction above the ball guide rod 7. Specifically, when the solenoid 15 is excited by applying a direct current, the plunger 18 contracts the coil spring 19 and is attracted to the solenoid 15, and when the solenoid 15 is demagnetized by cutting off the direct current, the plunger 18 is attracted. 18 projects forward due to the elasticity of the coil spring 19. Reference numeral 21 denotes a claw piece formed on the machine frame 16 to prevent the solenoid 15 from being removed. Further, a ball guide path 22 connected to the rear part of the ball guide path 14 is formed in an upper portion of the machine frame 16 in an orthogonal bent shape, and a pachinko ball that has won a normal winning opening 10 passes through the ball guide path 14 to the ball. It flows down to the conduit 22 and is discharged. In addition, protrusions having a width of about 1.5 to 3 mm are formed on the bottom surface of the normal winning opening 10 and the bottom surfaces of the ball guide path 14 and the ball guide path 22 so as to follow the flow direction of the pachinko balls. I try to roll on the strip.

  As shown in an enlarged view in FIG. 6, reference numeral 23 is a side surface that is pivotally supported so as to be able to repeatedly rotate in the machine frame 12 in order to transmit the movement of the plunger 18 of the solenoid 15 to the opening and closing blades 5 a and 5 b. The crank member 23 is an L-shaped crank member. The crank support 23 is integrally formed with shaft support portions 25a and 25b at both ends of the transverse shaft 24, and bifurcated portions 26a and 26b extend forward from the shaft support portion. Engaging portions 27a and 27b are formed extending upward and formed with engaging rods 28a and 28b that bend inward at the tip. The shaft support portions 25a and 25b are loosely fitted into a notch hole 29 formed in the rear edge portion of the machine frame body 12, the machine frame body 16 is fixed, and the notch holes are closed to thereby fix the shaft support portions 25a and 25b. Support for rotation. Then, the engaging pins 9a and 9b are loosely fitted to the bifurcated portions 26a and 26b, the crank member 23 is rotated about the shaft supporting portions 25a and 25b, and the engaging pins 9a and 26b are rotated by the bifurcated portions 26a and 26b. The open / close blades 5a and 5b are opened and closed by moving the 9b up and down. Further, the engaging rods 28a and 28b of the engaging portions 27a and 27b can be brought into contact with the back surface of the flange member 20 provided at the tip of the plunger 18 when the plunger 18 moves backward. Then, as shown in FIG. 4, when the plunger 18 is moved forward by the elasticity of the return coil spring 19, the flange member 20 is made to reach the bifurcated portions 26a and 26b. As described above, when the flange member 20 reaches the bifurcated portions 26a and 26b, the bifurcated portions 26a and 26b are prevented from moving upward, and the engaging pins 9a and 9b are also prevented from moving upward. For this reason, when the solenoid 15 is demagnetized, the opening and closing blades 5a and 5b cannot be forcibly opened forcibly. In this embodiment, a hanging piece 20a extends in front of the lower edge of the flange member 20 so that the hanging piece 20a can come into contact with the bifurcated portions 26a and 26b to be moved upward.

  On the other hand, when the solenoid 15 is excited, the plunger 18 is pulled backward against the elasticity of the return coil spring 19, and the hook member 20 pulls the engaging portions 27a and 27b as shown in FIG. Therefore, the crank member 23 is tilted backward with the shaft support portions 25a and 25b as fulcrums, and the bifurcated portions 26a and 26b push up the engagement pins 9a and 9b. Therefore, the opening and closing blades 5a and 5b are shown by two-dot chain lines in FIG. In this way, it is tilted (opened) in an inverted eight-letter shape so that the pachinko ball is easily won between the open / close blades 5a and 5b. When the solenoid 15 is demagnetized, the open / close blades 5a and 5b are closed in a parallel upright state again as shown in FIG. 4 due to the elasticity of the return coil spring 19. Therefore, even if an external force is applied to the opening / closing blades 5a, 5b in this closed state, the opening / closing blades 5a, 5b cannot be forcibly opened.

  The small hole 11 has a thin rod-like shape (not shown) from the front of the game board 32 for the purpose of cleaning by an administrator or eliminating ball clogging without aiming at fraud. 2), and the rod member 20 is pushed against the elasticity of the coil spring 19 so that the opening / closing blades 5a and 5b can be temporarily opened without exciting the solenoid 15. It is done. Accordingly, it is needless to say that the small holes 11 are provided as necessary, and are not necessarily provided in the present invention for the purpose of preventing fraud.

  Thus, in the electric variable prize-winning device according to the present invention, the open / close blades 5a and 5b cannot be forcibly opened by an external force unless the plunger is excited, so that it is effective to illegally win a game ball in a pachinko gaming machine. Can be prevented.
