Description

[Detailed description of the invention] [Field of industrial application] The present invention is a ball receiving device for a pachinko machine in which the movable wing pieces can be maintained in a tilted state as long as the electromagnet is energized. It is related to.

[Prior art] A pair of movable blades are pivoted on both sides of the front side of a ball inlet formed on a mounting plate so that they can stand up in parallel and tilt freely in an inverted figure-eight shape, and a guide box is attached to the rear surface of the mounting plate and the blades are inserted into the inside of the ball inlet. The front end of the movable wing piece is held upright by intervening below the axis of the movable wing piece on the transverse axis, and the ball that has entered between the upright movable wing pieces is guided to the rear end, and the weight of the ball lowers the rear end and the front end. In a ball receiving device that has a ball guiding plate pivoted to tilt the movable blades by flipping up the ball,
An opening actuation lever integrally equipped with an engagement piece and a permanent magnet that protrudes above the rear end of the ball guide plate is pivotally supported at one end of the horizontal shaft protruding outwardly of the guide box, and the opening operation lever is pivoted by energizing the electromagnet. A pachinko machine in which a permanent magnet is repelled downward with an acting force weaker than the ball weight to rotate an opening actuation lever, and its engagement piece pushes down the rear end of a ball guide plate to tilt a movable wing piece. A ball receiving device is well known, as disclosed in, for example, Japanese Utility Model Publication No. 58-4536 by the present applicant.

[Problems to be solved by the invention] However, in this ball receiving device, the electromagnet is fixed directly to the outer surface of the side wall of the guide box, so the impact caused by the passing of the ball is directly transmitted to the electromagnet, causing damage to the ball. As a result, there are problems such as disconnection of the coil, which can have very negative effects.

In addition, this ball receiving device is installed by inserting the guide box into a through hole drilled in the game board from the front side, and the hole is only large enough to allow the guide box to pass through. Therefore, during installation, there is a risk that the electromagnet may hit the edge of the through hole and be damaged.
Furthermore, since the electromagnets used are very small, the installation work is troublesome and it is difficult to install them in the correct position.

[Means for solving the problem] The present invention has a plurality of positioning holes bored in the side wall of the guide box on the side where the opening actuation lever is located, and
An electromagnet mounting cover is fixed to the outer surface of the side wall, and the electromagnet mounting cover has a U-shaped holding part and is formed with a fitting protrusion that fits tightly into the positioning hole. It houses and holds an electromagnet.

[Function] By fitting the positioning hole of the guide box with the fitting protrusion of the electromagnet mounting cover, the mounting position of the electromagnet can always be kept in the correct position, and the mounting work of the electromagnet is facilitated. In addition, the electromagnet is protected from direct contact with other objects such as a guide box and a game board to prevent accidents and damage.

[Embodiment] In the figure, 1 is a mounting plate with a ball inlet 2 in the center, and a pair of movable blades 3, 3 on both sides of the front side of the ball inlet 2 are arranged in parallel and inverted eight directions with shafts 4, 4. The glyph is pivoted so that it can tilt freely. 5 is a movable wing piece 3,
Mounting plate 1 covering both sides and the front side below the axis of 3.
6 is a guide box provided at the rear of the mounting plate 1, and inside thereof is a seesaw ball guide plate whose front end faces between the pair of movable wing pieces 3, 3. 7 is pivotally supported by a horizontal shaft 8. Reference numeral 9 denotes a metal rod horizontally suspended at the rear lower part of the guide box 6 in order to attract the magnet 10 attached to the lower surface of the rear end of the ball guide plate 7, and 11 denotes a ball extending from the lower front end of the ball guide plate 7. When the movable blades 3, 3 are standing up as shown by the solid line in Fig. 4, a ball hits the blades 3, 3 from above.
When the ball enters the gap, the ball is guided from the ball inlet 2 onto the ball guide plate 7 and flows backward, as shown by the chain line in Figure 5.The weight of the ball causes the front end to swing upward, causing the movable wing pieces 3, 3 to move upward as shown by the chain line in Figure 4. When the ball is tilted in an inverted eight-shape as shown in FIG. The function is to return the ball guiding plate 7 to its original state as shown by the solid line in FIG.

Reference numeral 12 denotes an opening operating lever pivotably supported on one end of the horizontal shaft 8 protruding outside the guide box 6,
An engaging piece 13 is provided at the rear end of the ball guiding plate 7 and projects from the rear end of the ball guide plate 7, and a permanent magnet 14 is fixedly provided on the outside.

Therefore, in the present invention, a plurality of positioning holes 15 are bored in the side wall of the guide box 6 on the side on which the opening lever 12 is pivotally supported, and the opening lever 12 is engaged with the rear end of the side wall. A notch 16 into which the mating piece 13 enters is formed. Reference numeral 17 denotes an electromagnet mounting cover, which has a U-shaped holding part 18 and a concave part 19' formed on the inner surface of a side plate 19 extending in the transverse direction to expose the head of the horizontal shaft 8 of the ball guiding plate 7. Information box 6
A fitting protrusion 20 is protruded from an end surface portion that abuts the side wall of the electromagnet 20 in alignment with the positioning hole 15, and an electromagnet 21 is accommodated and held in the holding portion 18. The electromagnet 21 is inserted into the groove 23 formed in the holding part 18 with the side protruding part of the iron core 22, and a heat sink 24 is interposed between the electromagnet 21 and the inner surface of the holding part 18, and the groove 23 is bored into the electromagnet 21. A small through hole 26 that matches the provided pin insertion hole 25 is bored, and a fixing pin 27 is driven into the small through hole 26, so that it is properly fixed and held at the predetermined position. And electromagnet mounting cover 17
The fitting protrusion 20 of this is tightly fitted into the positioning hole 15 of the guide box 6 and fixed by adhesive or the like. As a result, the electromagnet 21 is accurately and securely housed and held at a predetermined position inside the electromagnet mounting cover 17, and is also correctly positioned above the permanent magnet 14 of the opening lever 12. When the movable wing pieces 3, 3 are upright, the electromagnet 21 is energized by energization to generate a polarity that repels the permanent magnet 14 with an acting force weaker than the weight of the ball, and also swings the opening operating lever 12 downward. As a result, the engaging piece 13 of the opening actuating lever 12 accurately presses down the rear end of the ball guiding plate 7 and tilts the movable wing pieces 3 in an inverted figure-eight shape.

Incidentally, since the head of the horizontal shaft 8 of the ball guiding plate 7 faces the concave surface 19' of the electromagnet mounting cover 17 and is prevented from coming off, there is no need to provide troublesome measures to prevent the horizontal shaft 8 from coming off.

[Effects of the invention] As described above with respect to the embodiments, the invention has the following advantages:
An electromagnet 21 that faces the permanent magnet 14 of the opening lever 12 that is pivotally supported on one end of the horizontal shaft 8 that projects outwardly of the guide box 6 is housed and held at a predetermined position inside the electromagnet mounting cover 17, and the electromagnet mounting cover 1
A fitting protrusion 20 is drilled in 7, and the electromagnet is mounted by tightly fitting the fitting protrusion 20 into a positioning hole 15 bored in the side wall of the guide box 6 on the side where the opening operation lever 12 is pivotally supported. It is for fixing the cover 17,
The electromagnet 21 can be easily and easily installed in the guide box 6, and at the same time, the electromagnet 21 can always be installed in the correct position.

Moreover, since the electromagnet 21 is surrounded by the electromagnet mounting cover 17 and is reliably protected, there is no risk of it coming into contact with other objects and being damaged when the ball receiving device is installed. Furthermore, since the impact applied to the guide box 6 is not directly transmitted, it is highly durable with fewer failures.
