Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides a ball receiving device for a pachinko machine in which movable blades 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 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 guide plate pivoted to tilt the movable blade by flipping up the ball, 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 energization is turned on. A ball receiving device for a pachinko machine in which an electromagnet is excited to repel a permanent magnet with an acting force weaker than the ball weight, and the repulsive force pushes down the rear end of a ball guiding plate and tilts a movable blade. teeth,
For example, it is publicly known as disclosed in Publication No. 5G-S3 of the present applicant.

[Problems to be Solved by the Invention]However, since this ball receiving device continues to energize the electromagnet while the main energizing switch is on, there is a risk that the coil portion may burn out. There was that.

[Means for solving the problem] A normally closed auxiliary switch is connected in series in the energizing circuit for the electromagnet connected to the energizing main switch, and the normally closed auxiliary switch is attached 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,
When the rear end of the ball guide plate is lowered, a normally closed switch is opened via the intermediate member.

[When the energizing switch is turned on, the electromagnet 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 wing pieces. At the same time, the intermediate member supports the normally closed state. Approach the switch, open it, and stop energizing the electromagnet. Then, the ball enters between the tilted movable blades, and the ball guide lowers the leading end and swings the rear end up, causing the intermediate member to separate from the normally closed auxiliary switch and close it. Repeat the operation to re-energize the electromagnet.

[Example] In the figure, 1 is a mounting plate with a ball inlet 2 in the center, and a pair of movable wing pieces 3.3 are provided on both sides of the front surface of the ball inlet 2.
is supported by the shaft 4.4 so that it can stand in parallel and can freely tilt in an inverted eight-shape. Reference numeral 6 denotes a chatter fixed to the mounting plate 1 to cover the image side and front side above the axis of the movable wing piece 3°3, and 6 is a guide box provided at the rear of the mounting plate 1. A see-saw ball guide plate 7 whose tip faces between the pair of movable blades 3.3 is 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 1o attached to the lower surface of the rear end of the ball guide plate 7, and ■ denotes a ball extending from the lower end of the ball guide plate 7. With the receiving piece, movable wing piece 3
, 3 are standing up as shown by the solid line in Figure 1, when a ball enters between the wings 3 and 3 from above, the ball is guided from the ball inlet 2 onto the ball guiding plate 7 and flows backward. As shown by the R line in Figure J, the weight of the ball causes the tip to swing up, causing the movable blade 8.3 to tilt in an inverted eight-shape as shown by the chain line in Figure G, and in this state, the ball then moves the movable blade 3. 3, the ball raises the movable wing piece 3.3 and then rides on the ball receiving piece 11 to return the ball guide plate 7 to its original state as shown by the solid line in FIG.

The opening lever is pivotably supported on one end of the horizontal shaft 80 projecting outside the guide box 6, and has a locking piece series projecting above the rear end of the ball guide plate 7 at its rear end. A permanent magnet 14 is also fixed on the outside.

The head is an electromagnet, and the electromagnetic direction is held inside the mounting cover 16, which is a non-magnetic material, via a heat sink r, and the mounting cover 16 is held on the side where the opening lever ν of the guide box 6 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 is connected in series to a power source via a main switch for energization, which is turned on by, for example, a safe ball that enters another winning opening.

Another normally closed auxiliary switch 19 is connected in series to the energizing circuit of the electromagnet (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 916.

Further, the opening operating lever ν has an arm hanging downward, and an intermediate member 21 for opening the normally closed auxiliary switch 19 is provided on the side surface of this arm. The intermediate member 4 is, for example, a permanent magnet, and is positioned apart from the normally closed auxiliary switch 19 when the ball guiding plate 7 lowers its tip and holds the movable blade 3.3 in an upright state. When the actuating lever is pressed down, the ball guide plate 7 lowers its rear end and tilts the movable blades 3.3 to approach the normally closed auxiliary switch 19 and open it.

As shown in Fig. 2, when the movable blade 3.3 is upright, when the main switch for energizing is turned on, the electromagnet 1 is energized, creating a polarity that causes the permanent magnet k to emit y. wI
Swing the opening lever ratio downward as shown in the J3 diagram. As the opening actuating lever ν swings, its engagement piece ratio pushes down the rear end of the ball guide plate 7 and tilts the movable wing piece 3.3 in an inverted figure-eight shape. As a result, the intermediate member 2 provided on the opening actuation lever ν
Another permanent magnet approaches and faces the reed switch, which is the normally closed auxiliary switch 19, to open it and stop energizing the electromagnet. In this state, when the ball enters between the movable wing pieces 3.3,
Due to the weight of the ball, the movable wing pieces 3, 3 are raised up, and at the same time, riding on the ball receiving piece H, the tip of the ball guide plate 7 is lowered and the rear end is swung upward. As a result, the opening lever ν follows the movement of the ball guiding plate 7 and moves back to the position shown in FIG. Excite. Then, when the ball flows backward from the ball receiving piece (■) and is released from the weight of the ball, the ball guide plate 7 lowers its rear end due to the repulsive action of the electromagnet L and the permanent magnet 14 and moves the movable wing piece 3.3 again. At the same time as tilting, the intermediate portion 4
The 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 power supply switch is turned on.

FIG. 7 shows another embodiment of the present invention, in which the normally closed auxiliary switch 19 is constructed by a combination of a permanent magnet device and a reed switch section placed within the magnetic field range of the permanent magnet n, and the normally closed auxiliary switch 19 is The intermediate member 21 to which the opening 19 is to be opened is constructed by providing a magnetic piece U on the ball guiding plate 7. In the case of this embodiment, when the front end of the ball guiding plate 7 is lowered and the movable wing piece 3.3 is standing up, the magnetic piece of the ball guiding plate 7 is separated from the permanent magnet n, and the leakage of the permanent magnet n is prevented. The magnetic field increases, which causes
The reed switch n obtains the magnetic field necessary for the emotional value and turns on. Further, when the ball guide plate 7 tilts the movable wing piece by tilting the tip thereof, the example magnetic piece faces the permanent magnet n and becomes attracted, so that the magnetic field generated from the permanent magnet n is transferred to the magnetic piece 24. 'Since the FC is concentrated and the leakage magnetic field is reduced, the reed switch section cannot obtain the magnetic field necessary for the emotional value and is turned off.

[Effect of the invention] Since the movable blade 3.8 opens the normally closed auxiliary switch 19 when the movable blade 3.8 is in a tilted state and stops the energization to the electromagnetic correction, the burnout accident of the coil part in the electromagnetic direction is completely prevented. can be excluded.
