DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electromagnetic solenoid driving device and a winning device of a pachinko machine using the same, and more particularly to a driving structure suitable for driving an opening / closing member of the winning device of a pachinko machine.

[0002]

2. Description of the Related Art Conventionally, as described in JP-A-4-314474, JP-A-5-184715 and JP-A-6-47137, a prize winning device of a pachinko machine has been known. A structure in which a pair of open / close members called “tulips” are rotatably mounted on both sides, and the open / close members are opened / closed by a magnetic force of an electromagnet or the like is often used. The opening / closing member pivotally supported by the predetermined rotating shaft is normally held in a position to reduce the winning opening by the position of the driving member lowered by the leaf spring and its own weight, but when the electromagnet is excited. The opening / closing member is opened by the moving operation of the driving unit of the driving member that rotates toward the magnetic pole of the electromagnet, and the opening area of the winning opening is enlarged.

[0003]

As a driving device using the electromagnet, a hinge-type electromagnetic solenoid driving device in which a driving member is hingedly connected to a yoke of the electromagnet is used. The arm-shaped part is formed by extension, and this arm-shaped part is engaged with the opening / closing member as the driving part. Therefore, since the drive unit draws an arc-shaped movement trajectory, the engagement angle of the engagement unit with the opening / closing member changes according to the movement of the drive unit, so that smooth operation may not be performed. It is necessary to adjust the return operation and the return position with a leaf spring or the like, which makes assembly and adjustment difficult.

Further, since a hinge-type electromagnetic solenoid is used, it is difficult to give a large stroke to the drive member, and even when the stroke of the drive member is changed in accordance with the type of a pachinko machine, the electromagnetic solenoid itself is not used. It is necessary to change the position and the position of the drive unit, and there is a problem that simple design change cannot be performed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to make it possible to smoothly drive an opening / closing member of a pachinko machine and to drive the opening / closing member with a large stroke or to change a driving stroke. It can be easily performed, and even as an electromagnetic solenoid alone,
An object of the present invention is to realize a novel electromagnetic solenoid driving device and a winning device for a pachinko machine that can reduce manufacturing costs by simplifying an assembling operation.

[0006]

Means taken by the present invention to solve the above-mentioned problems include an electromagnetic coil formed by winding a coil around a coil spool having a core hole, and a magnetic coil attached to the electromagnetic coil. A yoke, a movable member inserted into the core hole so as to be protruded and retracted by excitation and demagnetization of the electromagnetic coil, and a drive unit attached to the movable member and acting on the outside by moving its position And a guide member extending in the direction of movement of the movable member is detachably attached directly or indirectly to the magnetic yoke, and the guide member engages with the drive member to move the movable member. An electromagnetic solenoid driving device configured to guide the driving member movably in a projecting / retracting direction of the member.

According to this means, since the drive member is attached to the movable member which is inserted into the core hole of the coil spool and moves in and out, the drive member can be moved linearly, so that it is always independent of the drive stroke. A constant driving state can be obtained, and the guide member is detachably attached directly or indirectly to the magnetic yoke, so that the driving member can be guided and stable operation can be expected. Since the guide member can be easily changed in accordance with the above, the drive stroke and the drive range can be easily changed.

Here, it is preferable that the guide member is fixed to a mounting plate that is mounted on the magnetic yoke.

In this case, by fixing the guide member to the mounting plate, the assembling work of the apparatus becomes easy and the positioning of the guide member becomes easy.

It is preferable that the guide member is engaged with the magnetic yoke and / or the electromagnetic coil and that the guide member is clamped and fixed between the magnetic yoke and the electromagnetic coil.

In this case, since the guide member engages with the magnetic yoke or the electromagnetic coil and is fixed by being sandwiched between them, it is easy to assemble and disassemble, and the guide member can be easily changed. Can be done.

In addition to the above configuration, the guide member includes
It is desirable to provide a stop for restricting the movement of the driving member in a direction away from the electromagnetic coil.

In this case, by providing the guide member with the stop, the operating range of the drive member can be reliably restricted.

And, as a winning device of the pachinko machine,
A pair of opening and closing members rotatably supported on both sides of the winning opening, and the electromagnetic solenoid driving device according to any one of claims 1 to 4, which is disposed behind the winning opening, The drive unit of the electromagnetic solenoid drive device is configured to engage with the opening / closing member to rotate the opening / closing member.

In this case, since the opening / closing member is driven by the above-mentioned electromagnetic solenoid driving device, the opening / closing member can be driven by the drive unit that moves linearly. The member can be operated, and malfunction can be prevented.

The fixing hole 55a is for inserting a fixing screw for attaching the electromagnetic solenoid driving device to a substrate described later.

A guide piece 60 is fixed to the lower portion of the mounting plate 50 using an adhesive or the like. The guide piece 60 includes a thin guide portion 61 and a stop portion 62 connected to a lower end of the guide portion 61. The guide portion 61 is shaped to fit into the notch 41 formed at the rear end of the drive plate 40, and guides the vertical movement of the drive plate 40 that moves in conjunction with the vertical movement of the movable iron core 30. It has become.

The lower end position of the driving plate 40 is determined. The driving plate 40 is always urged downward by the coil spring 31. However, the notch 41 abuts on the stop portion 62, and the driving portion 42, which will be described later, is engaged with the opening / closing member. It is stably held at a predetermined lower end position.

FIG. 3 shows an embodiment in which the above-described embodiment is applied to a winning device of a pachinko machine. (A) is a front view, (b)

Since the moving stroke of the drive plate 40 can be changed very easily only by changing the forming position, the electromagnetic solenoid can easily change the design such as the operation stroke and can easily cope with different models. A drive device can be configured.

The electromagnetic solenoid driving device can be formed very easily only by fitting the electromagnetic coil 10 to the magnetic yoke 20, and can be used for caulking, screwing, etc. of springs and other parts except for attachment to a substrate described later. Since it is not required at all, the assembly process is simplified and automation is possible, so that the manufacturing cost can be reduced.
