DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
1 and 2 are diagrams showing a ball winning device for a pachinko machine according to the present invention, in which the ball winning device includes a housing 1 and a ball receiving box 2 formed to protrude from the front surface of the housing 1. An opening / closing member 4 for opening and closing the upper opening of the ball receiving box 2, that is, the upward ball winning opening 3, and a solenoid 9 for operating the opening / closing member described later are configured. In the figure, the opening / closing member 4 is in a state where the ball winning opening 3 is opened. The housing 1 has a mounting frame 11 around its front surface. As shown in FIG. 2 (b), the mounting frame 11 contacts the base plate 6 when the housing 1 is inserted into the mounting hole 61 of the base plate 6. The housing 1 is screwed in contact therewith. Accordingly, the ball winning opening 3 protrudes forward from the base plate and is positioned between the base plate 6 (game board) and the glass plate. The thickness of the housing 1 (the thickness of the housing main body inserted into the mounting hole 61) is preferably equal to or less than the thickness of the base plate 6 so as not to protrude from the back surface of the base plate 6.
[0009]
As shown in FIG. 3, the opening / closing member 4 includes an upper cover plate 41, a cover plate rotating lever 42 extending downward from one end thereof, and a support shaft 43 extending downward from the other end thereof. The lever 42 includes a support shaft 44 and a distal end working piece 45. The left and right support shafts 43, 44 are pivotally attached to the side surfaces of both sides of the ball receiving box 2. In this way, the axial position of the opening / closing member 4 is shifted forward from the conventional one.
The mounting frame 11 of the housing 1 is provided with a pair of semi-annular fitting recesses 12, and the left and right side surfaces of the ball receiving box 2 are provided with corresponding fitting projections 21. Then, after the opening / closing member 4 is pivotally attached to the ball receiving box 2, the ball receiving box 2 is attached to the front surface of the housing 1 together with the opening / closing member 4 by fitting the fitting convex portion 21 into the fitting concave portion 12. be able to.
[0010]
As shown in FIGS. 3 and 4, a solenoid 9 to which a spring 91 and a plunger 92 are attached is vertically incorporated in the housing 1, and an operating member 93 is fitted into a head 921 of the plunger 92. However, an operating piece 94 extends downward from one end of the operating member 93 in an L shape. The actuating piece 94 pushes down the action piece 45 of the opening / closing member 4 when the plunger 92 is attracted downward by the solenoid 9 and rotates the lid plate 51 upward to open the ball winning opening 3. Since the opening / closing member 4 is rotated by the rotating shaft support system, energy can be efficiently used with little mechanical loss. Therefore, the opening / closing member 4 can be operated by the small solenoid 9. Further, since the plunger 92 is disposed in the vertical direction, wear of the plunger 92 can be reduced.
[0011]
Moreover, as shown in FIG. 5, the bottom surface of the ball receiving box 2 is provided to be inclined low toward one side so that balls flow. 3 and 4, a ball passage 13 through which balls from the ball receiving box 2 flow is formed in the front-rear direction of the pachinko machine on the bottom surface of the housing 1 connected to the one side of the ball receiving box. The ball passage 13 is provided with a ball counting device 8 that is inserted into the holding member 7 in an insertable manner. The ball counting device 8 is arranged in a vertical shape with a ball passage hole 81 for counting balls positioned in the ball passage and with the surface on the thin side facing the pachinko machine. The reason why the thin side of the ball counting device 8 is front and back is to suppress an increase in the thickness of the housing 1.
[0012]
As described above, in FIGS. 1 to 5, the solenoid 9 is energized and the plunger 92 is attracted downward, whereby the action piece 45 of the opening / closing member 4 is pushed down and the lid plate 41 is rotated backward. Therefore, the ball winning opening 3 is open.
On the other hand, in the ball winning device shown in FIGS. 6 and 7, the energization of the solenoid 9 is stopped, and the plunger 92 protrudes upward by the elastic force of the spring 91, thereby the action piece 45 of the opening / closing member 4. The push is released. Accordingly, the cover plate 41 is rotated forward by a weak spring force to close the ball winning prize opening 3. Since the biasing force in the closing direction of the lid plate 41 is weak, the ball is caught between the front inner side of the ball receiving box 2 and the front end of the lid plate 41 while the lid plate 41 is rotating in the closing direction. There is nothing. Further, when the lid plate 41 is in the closed state, the actuating member 93 serves as a stopper that stops the rotation when the lid plate 41 is pivoted upward. Therefore, the cover plate 41 in the closed state is not opened due to the momentum of the falling balls. In addition, since the solenoid 9 is energized only when the ball winning prize opening 3 is opened, power consumption can be reduced.
[0013]
The ball winning prize port 3 does not need to be completely closed. As shown in FIG. 7B, the opening / closing member 4 may be tilted forward so that the ball cannot pass. The rotation stroke of the opening / closing member 4 can be made small, and therefore the solenoid 9 can be operated efficiently. Moreover, as shown in FIG. 6, since the upper surface of the cover plate 41 is inclined low toward the left and right of the pachinko machine, balls can be discharged smoothly from the top of the cover plate 41. Moreover, since the upper surface of the cover plate 41 is curved with a bulge in the front-rear direction, the impact when the ball falls on the cover plate 41 in the closed state can be reduced. Furthermore, as shown in FIG. 11, by tilting the front wall upper end 22 of the ball receiving box 2 to the left and right, the balls can be discharged to both sides more smoothly.
[0014]
【The invention's effect】
As described above, the winning device for the pachinko machine according to the present invention is provided with a ball receiving box having an upper opening on the front surface of the housing so that the ball winning opening is directed upward and protrudes forward of the base plate. Since the opening / closing member is pivotally mounted on the side surface of the door, the solenoid for operating the opening / closing member can be accommodated in the housing, and the solenoid may protrude from the back surface of the base plate as in the past. Absent.
Therefore, this invention has the big advantage that the back space of a baseplate can be used effectively.
