Description

[Detailed description of the invention] [Field of industrial application] This invention is equipped with a pair of opening and closing wings that can stand up and tilt freely on the front of the mounting plate, and the opening and closing wings are illuminated with a lamp from the rear of the mounting plate. This invention relates to a safe ball receptacle for pachinko machines, which prevents the conductive parts of the wiring board from being shot due to contact with balls.

[Prior Art] The present applicant has formed a pair of opening/closing wings made of transparent synthetic resin into a hollow shape with an open rear side, which are pivotally supported so as to be able to stand up and tilt freely on the front surface of the mounting plate. First, in 1983, a safe ball socket was created, in which a wiring board with a lamp was attached to it using screws, and when the lamp was turned on, the opening and closing blades were illuminated with light to create a decorative effect. - Proposed by No. 165465.

[Problems to be solved by the invention] However, in this safe ball socket, the conductive parts such as the printed wiring for lighting the lamp, the lamp pin plug, and the soldered part of the wiring cord are placed on the rear side of the wiring board. Because it is placed in an exposed state, there is a risk that, for example, a ball that enters another winning slot and is guided to the safe ball socket by the guide gutter provided on the back side of the game board may come into contact with the conductive part and shoot. It was hot.

[Means for Solving the Problems] In view of the above, the present invention is such that an insulating cover is attached to the rear side of the wiring board to cover the conductive portion.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. In the figure, 1 is a mounting plate with a ball inlet 2 in the center, and 3, 3 is a pair of opening/closing wings that are supported on both sides of the front side of the ball inlet 2 by shafts 4, 4 so that they can stand parallel to each other and can freely tilt in an inverted eight shape. It is a hollow piece with an open rear side made of colored transparent synthetic resin. Reference numeral 5 denotes a chucker fixed to the mounting plate 1 to cover the area below the shafts 4, 4 of the opening/closing wings 3, 3, and 6 is a guide box provided on the rear surface of the mounting plate 1. A ball guiding plate 8 is pivotally supported on the horizontal shaft 7. The ball guide plate 8 intervenes below the axes 4, 4 of the opening/closing blades 3, 3 at the tip as shown by the solid line in FIG. It acts to tilt the pieces 3, 3.

Reference numerals 9 and 9 refer to tube portions for inserting lamps provided at the left and right outer positions of the guide box 6 so as to correspond to the rear sides of the respective opening/closing wing pieces 3, 3, respectively, and 10 refers to the center portion of the upper edge of the rear surface of the guide box 6. 11 is a wiring board.

As shown in FIG. 2, the wiring board 11 is formed in a U-shape so as to straddle the upper edge of the rear surface of the guide box 6 and the left and right sides, and has a through hole 12 formed in the center of the upper part.
In addition, the wiring board 11 has a printed wiring board 13 on the rear side.
Then, the protruding ends of a plurality of pin plugs 14 penetrating from the front side to the rear side of the wiring board 11 are soldered to the printed arrangement 13, and the arrangement cord 15 is further soldered. pin plug 1
4 are provided as a set of two, two in each of the upper and lower positions on both sides of the wiring board 11, for a total of four locations.

Then, the wiring board 11 attaches the lamps 16, 16' and 17, 17' to each pin plug 14, and also puts the inner side against the upper end of the rear surface of the guide box 6 to match the screw insertion hole 10 and the through hole 12. Screw the screw 18 from the through hole 12 into the screw insertion hole 10 and tighten it, thereby integrally attaching it to the guide box 6, and inserting the lamps 16 and 16' on both sides of the lower part into the cylindrical parts 9 and 9, respectively. The lamps 17, 17' on both sides of the upper part are positioned opposite to each other behind the transparent part of the mounting plate 1.

Reference numeral 19 denotes a plate-shaped insulating cover made of an electrically insulating material such as synthetic resin, which is formed in a U-shape to cover the rear side of the wiring board 11, and a slight gap 20 is formed between it and the wiring board 11. The left and right sides are bent outward so that the left and right sides are bent outward, and a through hole 21 that matches the through hole 12 of the wiring board 11 is formed in the center of the upper part.
to be drilled. Then, this insulating cover 19 is brought into contact with the rear side of the wiring board 11 so that the through holes 12 and 21 are aligned with each other, and the insulating cover 19 is fixed to the wiring board 11 by tightening the screws 18.

In the safe ball receiver of the present invention configured as described above, when the lamps 16, 16' and 17, 17' are turned on, the lamps 16, 16' are opened and closed by the opening and closing blades 3, 3.
The hollow interior of the lamp is illuminated, and the lamps 17 and 17' illuminate the mounting plate 1 to create a beautiful atmosphere. Then, all conductive parts such as the printed wiring 13 of the wiring board 11, the pin plugs 14, and the soldered parts of the wiring cords 15 are covered with an insulating cover 19 so that they are not exposed to the back side of the game board 22, and the balls come into contact with the conductive parts. to ensure that prevention of Furthermore, since a slight gap 20 is formed between the wiring board 11 and the insulating cover 19, even if the soldering part is raised, the installation of the insulating cover 19 will not be hindered, and the wiring cord By inserting the wiring cord 15 into the gap 20, the wiring cord 15 can be reliably fixed at a position above the guide box 6 where it will not affect the outflow of the balls.

[Effects of the invention] As described above with respect to the embodiments, the invention has the following advantages:
Since all conductive parts such as printed wiring, lamp pin plugs, and soldered parts of wiring cords are covered with insulating covers, it is possible to completely eliminate shoot accidents caused by contact with balls.
