  By the way, this type of electric variable prize-winning device is required to be durable enough to withstand millions of operations in order to avoid troubles with players, but it can be opened and closed by repeatedly moving the solenoid plunger. Since the blades are movable, the shock and vibration may cause looseness of the solenoid mounting screw or wear of the engaging claws, causing play, and the plunger moves forward and backward with a sufficient stroke. There was a risk of malfunction. Further, since it takes time to assemble with screws, there is a drawback that productivity is not improved.

  The present invention is to solve the above problems, and in an electric variable prize winning device configured such that an opening / closing blade is moved by moving a plunger forward and backward of a solenoid, a ferromagnetic metal plate is provided at a rear portion of the solenoid. A projecting piece is formed by slightly projecting the rear end edge of the yoke in the width direction, and a rectangular accommodating portion whose front surface is open is formed integrally with a plastic machine frame body, and the accommodating portion is opposed to it. An engagement hole is formed in a rear portion of at least one of the side walls, a rear end portion of the solenoid is inserted into a front opening of the accommodating portion, and the side wall is temporarily elastically deformed outward by the projecting piece to be restored. By engaging the projecting piece with the engaging hole, the solenoid is fixed to the housing portion so as not to be removable.

  In this electric variable prize-winning device, the solenoid is assembled easily and securely, and there is no risk of malfunction even after long-term use, and durability is improved.

  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 rear perspective view, and FIG. 4 is a longitudinal sectional view. 5 and 6 are exploded perspective views thereof. In the figure, reference numeral 1 denotes a mounting board having a ball opening 2 in the center, 3 denotes a ball receiving member fixed to the front surface of the mounting board by screws 4, and 5 a and 5 b denote the ball receiving parts on the front surface of the mounting board 1. A pair of opening and closing blades pivotally supported by supporting shafts 6a and 6b provided in the member so as to be able to stand upright and reverse in an octagonal manner. A slowly-inclined sphere guide rod 7 is provided. A pair of long holes 8a and 8b are opened in both sides of the entrance 2 on the mounting substrate 1 in a shape curved in an arc shape centering on the support shafts 6a and 6b. Engagement shafts 9a and 9b are integrally formed on the back surfaces of the opening and closing blades 5a and 5b, and the tips of the engagement shafts are loosely fitted into the long holes 8a and 8b so that the tips of the engagement shafts are guided to the sphere. It protrudes from the back surface of the mounting substrate 1 on both outer sides of the flange 7. Reference numeral 10 denotes an ordinary winning opening formed on the top of the mounting substrate 1. 1a and 1b are screw through holes 1c and 1d 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 the rear ends of the support shafts 6a and 6b are It is the bearing part formed in the front surface of the attachment board | substrate 1 so that it may penetrate and be fixed.

  The ball guide rod 7 has a U-shaped cross section formed integrally with the lower center of the machine frame 12 fixed to the back surface of the mounting substrate 1 with screws 11, and a gap is appropriately provided on both sides of the ball guide rod 7. Wall plates 13a and 13b are integrally formed in a hanging shape with a gap therebetween. Further, the machine frame 12 is made of plastic, and a ball guide path 14 that is continuous with the rear surface of the normal winning opening 10 is formed integrally therewith.

  Reference numeral 15 denotes a solenoid. The solenoid has a planar U-shaped yoke 16 formed by press-molding a ferromagnetic metal plate as an outer shell, and a connecting plate 17 made of a ferromagnetic metal material is connected to both ends of the yoke. A conductive coil 18 is provided in the yoke, and a plunger 19 made of a ferromagnetic metal material is disposed at the center of the conductive coil so as to be able to advance and retreat in the axial direction. The plunger is connected to the center of the connecting plate 17. A return coil spring 20 is attached to the outer periphery of the plunger from the hole so that the coil spring is compressed between the front surface of the solenoid 15 and the tip flange 19a of the plunger 19. Yes. In the present invention, the projecting piece 21 is formed by causing the rear end edge of the yoke 16 to protrude slightly in the width direction (about 1 mm) from the other part at the rear part of the solenoid 15. When the solenoid 15 is excited by applying a direct current to the conductive coil 18, the plunger 19 contracts the coil spring 20 and is attracted to the solenoid, and when demagnetized, the plunger 19 is pulled by the elasticity of the coil spring 20. Projects forward.

  Reference numeral 22 denotes a plastic second machine frame body, which is integrally formed with a rectangular housing portion 23 whose front surface is open, and at least one of the opposite side walls 23a and 23b of the housing portion. An engagement hole 24 having a horizontally long hole is formed in the rear part. The inner width W1 of the side walls 23a and 23b is substantially the same as the width W2 of the yoke 16 of the solenoid 15. However, the side walls 23a and 23b have a slight die-cutting gradient necessary for plastic molding ( In the front opening of the housing portion, the inner width W1 is such that it can enter the housing portion including the protruding piece 21. ing. Reference numeral 25 denotes a claw piece formed integrally with the front edge of the other side wall 23b.

For this reason, when the rear end portion of the solenoid 15 is inserted into the front opening of the housing portion 23 of the machine frame 22 and the solenoid 15 is pushed into the housing portion 23, the side walls 23 a and 23 b are temporarily moved outward by the protruding pieces 21. It is elastically deformed, and the projecting piece engages with the engagement hole 24 to restore the deformation. For this reason, the solenoid 15 is fixed in the accommodating portion 23 so as not to be removable with the protruding piece 21 engaged with the engaging hole 24. At this time, the claw piece 25 is engaged with the front surface of the solenoid 15. However, even if the claw piece 25 is not provided, the solenoid 15 is securely fixed in the accommodating portion 23.
After the solenoid 15 is assembled in the machine frame 22 in this way, the machine frame 22 is fixed to the rear side of the machine frame 12 with screws 27.

  In addition, a ball guide path 26 continuous with the rear part of the ball guide path 14 is formed in an upper portion of the machine frame body 22 in an orthogonal bent shape, and the pachinko ball that has won the normal winning opening 10 passes through the ball guide path 14 to the ball. It flows down to the conduit 26 and is discharged. Further, a protrusion having a width of about 1.5 to 3 mm is 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 26 along the flow-down direction of the pachinko sphere. I try to roll on the strip.

30 is a transmission member for transmitting the movement of the plunger 19 of the solenoid 15 to the open / close blades 5a, 5b. The transmission member is integrally formed with a pair of side plate portions 32a, 32b having substantially L-shaped side surfaces at both ends of the transverse shaft 31. Support shafts 33a and 33b are integrally formed on both outer surfaces of the side plate portion in the vicinity of the intermediate refraction portion. The support shaft is loosely fitted in a notch hole 34 formed in the rear edge of the machine frame body 12, and the support shaft is rotatably supported by fixing the machine frame body 22 and closing the notch hole. . Further, bifurcated portions 35a and 35b are formed at the front end edges of the side plate portions 32a and 32b, and the tips of the engagement shafts 9a and 9b are loosely fitted into the bifurcated portions.
Further, a transverse shaft 36 is formed between the upper side plates 32a and 32b of the transmission member 30 so that the front surface of the distal end flange portion 19a of the plunger 19 abuts, and is formed so as to protrude from the inner surfaces of the side plates 32a and 32b. The cantilever shafts 37a and 37b that are in contact with the back surface of the tip flange portion 19a are formed.

  In the electric variable prize winning apparatus configured as described above, when the solenoid 15 is demagnetized, the plunger 19 is projected forward due to the elasticity of the coil spring 20, so that the tip of the plunger as shown in FIG. The flange portion 19a presses the transverse shaft 36, the transmission member 30 tilts forward with the support shafts 33a and 33b as fulcrums, and the bifurcated portions 35a and 35b push down the engagement shafts 9a and 9b. In this state, the pachinko ball is difficult to win between the opening and closing blades 5a and 5b. When the solenoid 15 is energized, the plunger 19 is pulled backward against the elasticity of the coil spring 20, so that the tip flange portion 19a pulls the cantilever shafts 37a and 37b, tilts the transmission member 30 backward, and bifurcates. Since the shaped portions 35a and 35b push up the engagement shafts 9a and 9b, the opening and closing blades 5a and 5b tilt in an inverted octagonal shape as shown by a two-dot chain line in FIG. 1, and between the opening and closing blades 5a and 5b The ball is ready to win. The pachinko balls that have flowed down between the opening and closing blades 5a and 5b flow into the ball guide rod 7 from the entrance 2 and are discharged from the rear end of the ball guide rod 7.

  As described above, in the solenoid mounting structure of the electric variable prize-winning apparatus according to the present invention, the solenoid can be easily fixed with a single touch only by inserting the solenoid 15 into the housing portion 23, so that the assembly work is facilitated and the productivity is improved. Further, the impact / vibration associated with the solenoid 15 being actuated and the plunger 19 being repeatedly advanced and retracted is applied to the engaging hole 24 from the projecting piece 21, and the force is applied in a direction parallel to the side wall 23 a, so that the side wall However, it hardly deforms even with the repeated load. For this reason, there is no possibility that the solenoid will be loosened and become loose even after long-term use, and durability will be improved, and a highly reliable product that will not cause malfunction even after long-term use is provided. Can do.

  In this embodiment, an example in which the solenoid is provided horizontally has been shown, but the solenoid mounting structure of the present invention can also be applied to a variable winning device in which the solenoid is provided in a bowl or in an inclined shape.
