Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides 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 continues to be 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 guide box is inserted into the inside of the ball inlet. The front end of the movable wing is held upright by intervening below the axis of the movable wing on the transverse axis, and the ball that has entered between the upright movable wing is guided to the rear end and the weight of the ball lowers the rear end. In a ball-striking receiver that has a ball guide plate pivoted to tilt the movable blade by flipping up the front end, a permanent magnet is placed at the rear end of the ball guide plate, an electromagnet is attached to the guide box, and the main switch for energizing is installed. A ball striking machine for a pachinko machine in which an electromagnet is excited when turned on to repel a permanent magnet with an acting force weaker than the weight of the ball, and the repulsive force pushes down the rear end of the ball guiding plate and tilts the movable blade. The mouthpiece is known, for example, as disclosed in 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 continues to be energized while the main energizing switch is turned on, so there is a risk that the coil portion may burn out. It was hot.

[Means for solving the problem] Connect a normally closed auxiliary switch in series in the energizing circuit for the electromagnet connected to the main energizing switch, and attach the normally closed auxiliary switch to the guide box of the ball socket. At the same time, an intermediate member for opening the normally closed auxiliary switch is attached to the ball guide plate, and when the rear end of the ball guide plate is lowered, the normally closed switch is opened via the intermediate member.

[Operation] When the energizing switch is turned on, the electromagnetic magnet is excited and repulses the permanent magnet with an acting force weaker than the weight of the ball, pushing down the rear end of the ball guide plate and tilting the movable blade. At the same time, the intermediate member approaches the normally closed auxiliary switch, opens it, and stops energizing the electromagnet. and,
A ball enters between the tilted movable blades, and by lowering the tip of the ball guiding plate and swinging the rear end up, the intermediate member is separated from the normally closed auxiliary switch, closing it. Then, the operation of re-energizing the electromagnet is repeated.

[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 above the axis of 3.
6 is a guide box provided at the rear of the mounting plate 1, and inside it is a seesaw ball guide plate whose tip faces between the pair of movable wing pieces 3, 3. 7 is pivotally supported by a horizontal shaft 8.

9 is a magnet 1 attached to the lower surface of the rear end of the ball guide plate 7
A metal rod 11 is installed horizontally at the rear lower part of the guide box 6 to attract 0, and 11 is a ball receiving piece extended to the lower part of the tip of the ball guide plate 7. When the ball is standing up like this, the ball hits the wing pieces 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 tip to swing upward, causing the movable wing pieces 3, 3 to move as shown in 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.

Reference numeral 15 denotes an electromagnet, and this electromagnet 15 is held inside a non-magnetic mounting cover 16 via a heat sink 17, and the mounting cover 16 is held on the side of the guide box 6 on which the opening lever 12 is pivotally supported. By fixing it to the side wall, it can be mounted above the permanent magnet 14 in a correct opposing position. The electromagnet 15 is connected in series to a power source via a main switch 18 for energization, which is turned on by a safe ball entering another winning opening, for example.

Another normally closed auxiliary switch 19 is connected in series to the energizing circuit of the electromagnet 15 (see FIG. 6). This normally closed auxiliary switch 19 is, for example, a reed switch, and is fixed to the mounting cover 16 and attached to the side wall of the guide box 6. The opening lever 12 has an arm 20 hanging downward, and an intermediate member 21 for opening the normally closed auxiliary switch 19 is provided on the side surface of the arm 20.
The intermediate member 21 is, for example, a permanent magnet, and the ball guide plate 7
When the tip is lowered to hold the movable blades 3, 3 in an upright state, the ball guide plate 7 is positioned apart from the normally closed auxiliary switch 19, and when the opening actuating lever 12 is pressed down, the ball guide plate 7 lifts the rear end. By tilting the movable wing pieces 3, 3 by lowering them, they approach the normally closed auxiliary switch 19 and open it.

Therefore, as shown in FIG.
When the main energizing switch 18 is turned on while the main switch 18 is standing up, the electromagnet 15 is excited and has a polarity that repels the permanent magnet 14, causing the opening lever 12 to swing downward as shown in FIG. This opening lever 1
2, the engaging piece 13 pushes down the rear end of the ball guiding plate 7 and tilts the movable wing pieces 3, 3 in an inverted eight-shape. As a result, the permanent magnet serving as the intermediate member 21 provided on the opening actuating lever 12 operates as the normally closed auxiliary switch 1.
The reed switch 9 is approached and opened, and the energization to the electromagnet 15 is stopped. When the ball enters between the movable wing pieces 3 and 3 in this state, the weight of the ball causes the movable wing pieces 3 and 3 to rise, and at the same time the ball receiving piece 11
, and lower the tip of the ball guiding plate 7 and swing the rear end upward. With this, the opening actuation lever 12 is moved to the ball guide plate 7.
2, the intermediate member 21 separates from the normally closed auxiliary switch 19, closes it, and excites the electromagnet 15 again. and,
When the ball flows backward from the ball receiving piece 11 and is released from its extreme weight, the ball guide plate 7 lowers its rear end due to the repulsive action of the electromagnet 15 and the permanent magnet 14 and moves the movable blades 3, 3 again. At the same time as the tilting, the intermediate member 21 approaches the normally closed auxiliary switch 19, opens it, and stops energizing the electromagnet 15. This operation continues as long as the main energization switch 18 is turned on.

FIG. 7 shows another embodiment of the present invention, in which the normally closed auxiliary switch 19 is connected to a permanent magnet 22 and the permanent magnet 2
The intermediate member 21 for opening the normally closed auxiliary switch 19 is constructed by providing a magnetic piece 24 on the ball guide plate 7. In this example,
When the ball guide plate 7 has its front end lowered and the movable blades 3, 3 are upright, the magnetic piece 24 of the ball guide plate 7 is attached to the permanent magnet 2.
2, the leakage magnetic field of the permanent magnet 22 increases, whereby the reed switch 23 obtains the magnetic field necessary for the emotional value and turns on. Further, when the ball guide plate 7 tilts the movable blade by tilting the tip thereof, the magnetic piece 24 faces the permanent magnet 22 and becomes attracted to it, so that the magnetic field generated from the permanent magnet 22 becomes magnetic. Since the leakage magnetic field concentrates on the piece 24 and decreases, the reed switch 23 cannot obtain the magnetic field necessary for the emotional value and is turned off.

[Effects of the Invention] When the movable blades 3, 3 are in a tilting state, the normally closed auxiliary switch 19 is opened to stop the energization to the electromagnet 15. Therefore, the burnout accident of the coil portion of the electromagnet 15 can be completely prevented. can be excluded.
