Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winning device provided on the game board surface of a pachinko machine, and particularly to a winning device in which a receiving member for winning balls rotates.

Conventionally, as a highly hobbyist winning device whose form changes every time a prize is won, a device with a pair of ball-receiving pieces that opens and closes, commonly called a chulip, has been used for a long time.

It is true that this tube device has been used extensively due to its ingenuity and simplicity, as well as the thrill of being able to receive several shots at the same time when the ball receiver opens, but it is about time I don't hear people saying they are getting tired of it.

Therefore, the present invention provides an electromagnetic structure that operates by providing a plurality of sockets on the circumferential surface of a winning ball receiving member and rotating the winning ball receiving member by a predetermined angle to align the sockets with the intake port. The present invention aims to provide a winning device with a new form change in place of the chulip by changing the receiving state of game balls. Then, a winning ball detecting device for detecting a batted ball that has entered the socket and a winning ball detecting device provided in another winning device of the game board are electrically connected to the electromagnetic structure to rotate the winning ball receiving member. By controlling the game content, the content of the game can be diversified and varied. In addition, the winning ball receiving member is rotatably driven by an electromagnetic structure that uses electric magnetic force instead of a purely mechanical system that uses the weight of the winning ball to achieve easy braking and a moderate and stable conversion operation. It has been made possible to do so.

Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. First, from FIG. The explanation will start from the one in which the ball faces the winning ball intake port alternately at a rotation angle of .degree.

Figures 1 and 2 are perspective views from the front and rear, respectively, and Figure 3 is a longitudinal cross-sectional view. In order to install this winning device 1, there is a mounting plate 2 on the board, and the mounting plate has an opening 3 for taking winning balls into the back of the board, which communicates with the mounting plate. There is a passage 4 for sending the balls to a well-known winning ball flow down channel (not shown) on the back of the board, and this passage 4 is provided in the housing 5. The housing 5 is provided with a ball outlet 6 to the lower gutter where the winning balls flow.

In a general ticket device, a pair of receiving pieces that open and close are provided at the front of such a structure, but in the present invention, a rotating winning ball receiving member 7 is provided.

In the case of this embodiment, the winning ball receiving member 7 (hereinafter simply referred to as the receiving member) is fixed to a rotating shaft 8 that is rotatably supported through the mounting plate 2, and both the rotating shafts rotate. be able to. Particularly in this case, the rotating shaft 8 passes through the rear wall 5a of the housing 5 at the other end, and is stably supported at these two penetration points.

In this case, the receiving member 7 has an arrowhead shape when viewed from the front, and can support winning balls at two positions facing each other in the diametrical direction around the rotating shaft 8.
a socket part 9a that can be diverted to the intake port 3;
9b. In the drawing, the upper socket part 9a has a recessed shape with a large sloped surface that guides the winning balls P to the intake port 3, and therefore, in some cases, several balls may win. On the other hand, the socket part 9b which is not aligned with the intake port 3 at this position in the lower part of the drawing is the part 6B described later.
As shown in the figure, when rotated and aligned with the intake port, it has a small depression shape that allows the flow to flow to the intake port if only one ball P is properly placed thereon.

Therefore, at a position at the rear of the mounting plate of the rotating shaft 8 supporting the receiving member 7, in this case, at the rear end position penetrating the rear wall 5a of the housing 5, there is a part of the electromagnetic structure. A permanent magnet piece 10 as a rotor is attached. A pair of magnetic poles 1 are located at diametrically opposed positions close to the rotation locus of the diametrically opposed outer edges 10a and 10b of the permanent magnet piece 10.
An electromagnetic member 11 with 1a and 11b facing is provided as a part of the electromagnetic structure, and with one socket 9a of the receiving member 7 shown in FIGS. 1 and 2 aligned with the opening 3, the permanent magnet Both outer edges 10a, 10b of the piece and both magnetic poles 11a, 11b of the electromagnet are aligned in the diametrical direction.

Therefore, at the initial stage, even if the coil 11' of the electromagnet 11 is not energized, the permanent magnet piece 10 is moved by its magnetic force to both magnetic poles 11a, 11b.
and maintain a consistent position.

In this winning device, a known winning ball detecting device (micro switch, photoelectric switch, etc.) is installed in the winning ball flow down channel communicating from the ball outlet 6, and the winning ball detecting device and the electromagnetic member 11 are connected to each other. When electrically connected, the winning ball that has entered the intake port 3 can be detected by the winning ball detection device, the electromagnetic member 11 can be excited, and the winning ball receiving member 7 can be rotated. That is, this winning device can change the acceptance state of a batted ball in conjunction with the batted ball accepted by the winning device itself.

An example of this will now be explained with reference to FIG. 4 and subsequent figures.

In FIG. 4, the magnetic structure is particularly enlarged and shown, and the upper end 10 is in the state of the permanent magnet piece 10 when the socket part 9a is aligned with the intake port.
The case where a is the north pole and the lower end 10b is the south pole is shown.

It is assumed that a winning ball P enters the socket 9a, is guided to the intake port 3, is taken in through the passage 4 and the ball outlet 6, and is detected by the winning ball detection device S.
A suitable drive current source 12 that operates in response to this detection signal is provided, and a drive current I _F is applied to the coil 11' of the electromagnet 11 in a direction such that the opposite poles of the permanent magnet pieces have the same polarity. Flow. As a result, due to the generated magnetic repulsion force, the permanent magnet piece 10
rotates in either direction to escape from both magnetic poles of the electromagnet. At this time, the dynamic rotation system consisting of the permanent magnet piece 10, the rotating shaft 8, and the receiving member 7
Deliberately change the balance, for example, by adding a weight 13 to a part of the receiving member 7 because it is light (see Figure 2).
etc., the rotation direction can be determined in the direction of this weight (arrow R). In this case, since the weight 13 is on the right side when viewed from the front, the receiving member starts rotating in the clockwise direction R, and the receiving member starts rotating in the clockwise direction R.
The permanent magnet piece 10 rotates counterclockwise.

From FIG. 5A onward, the state of rotation of the permanent magnet piece 10,
The rotation of the receiving member 7 corresponding to FIG. 6A and subsequent figures is shown from the back side and the front side, respectively.
Start rotating from the state shown in the figure and use the momentum of the rotation to 180 degrees.
When the poles 10a and 10b are rotated close to 10°, each pole 10a and 10b becomes close to the electromagnet magnetic poles 11b and 11a of different polarity, so a force of attraction is generated in the opposite direction, and the poles 5B and 6
As shown in Figure B, when the magnets are rotated 180 degrees and aligned with the magnetic poles of the electromagnets of different polarity, they are braked to maintain that position. At this time, the receiving member 7 is in a state where the other smaller socket portion 9b is aligned with the inlet 3.

Note that by controlling the supply time of the current I _F from the drive current source 12 using a known timer circuit,
The state change of the receiving member may be controlled.

Therefore, each time the drive current source 12 in FIG. 4 receives a detection signal from the winning ball detection device S, the coil 1
1' (it is obvious to those skilled in the art to configure such a circuit), the ball enters the second socket 9b facing upward, and this By detecting this and supplying a reverse current I _R (FIG. 5C) to the coil 11', the receiving member 7 can be rotated so that the first socket part 9a is aligned with the mounting opening 3 again. (Figure 6C).

The magnetic action at this time is exactly the same as above except that NS is reversed, but since the weight 13 of the receiving member 7 sandwiches the rotating shaft 8 and is on the opposite side, the permanent magnet due to magnetic repulsion, The rotating direction of the rotating shaft and the receiving member is counterclockwise R', which is opposite to the above. However, in the end, the first socket portion 9a can be returned to the state shown in the first to fourth figures, and the same operation can be repeated alternately thereafter.

In the above explanation, when the winning ball P entering the socket 9a, which is easy to receive game balls, is detected, the winning ball receiving member 7 is rotated to align the socket 9b with the opening 3, so that it is difficult to receive game balls. However, when a winning ball entering the socket 9b, which is difficult to accept a hit ball, is detected, the winning ball receiving member 7 may be rotated to change the state to a state where it can easily accept a game ball.

The operation of the electromagnet member 11 can be electrically linked to winnings in other winning devices. for example,
A winning ball detection device for detecting a game ball that enters another winning device is provided, and the winning ball detection device and the driving current source 12 are provided.
electrically connect the In this way, it is possible to operate the electromagnetic structure based on the detection signal of the winning ball that has entered the other winning device, and to control the rotation of the winning ball receiving member 7. In addition, to limit the rotation direction to a predetermined direction, instead of mechanically breaking the state and dynamic balance, for example, a permanent magnet piece 10
It is also possible to make the shapes of the edges 10a, 10b asymmetrical with respect to a longitudinal line passing through the central axis, thereby making the magnetic force asymmetrical. The above considerations also apply to each of the embodiments described below.

In the case of the first embodiment described above, the sockets 9a, 9b
To maintain the state in which one of them is aligned with the intake port 3, when the current to the coil 11' is cut off, the permanent magnet piece 10 itself is magnetically attracted to the electromagnet magnetic poles 11a and 11b as opposing magnetic body parts. It depends only on force. Therefore, the state of the receiving member 7 may be stabilized by electromagnetic force by continuously supplying current to the coil 11'. However, if the coil 11' is de-energized for reasons such as saving power consumption, the receiving member 7 may wobble from side to side when the ball hits the side surface of the receiving member 7.
It is also expected that it will be quite difficult to get into the receiving section.

To prevent this, the alignment of the sockets 9a and 9b with the intake port 3 is maintained, and only when the coil is energized,
The embodiments shown in FIGS. 7 to 9 are examples in which rotation is ensured. Also in this case, for the sake of simplicity, most of the structure is shown as the same as that of the first embodiment, so the following description will mainly focus on the modified parts.

On the surface of the mounting plate 2, there is a protrusion 14 located on the back side of the receiving member 7, and on the receiving member, recesses 15, 15 for accommodating the protrusion are provided point-symmetrically about the rotation axis 8. Depending on which of the sockets 9a, 9b is aligned with the intake port 3, the projection 14 is fitted into the corresponding recess 15.

On the other hand, both end edges of the permanent magnet piece 10 and the outer peripheral surface of the magnetic poles are tapered toward the rear in the axial direction, and correspondingly, the magnetic pole surfaces of the magnetic poles 11a and 11b of the electromagnet 11 facing this surface are also tapered. It is attached. At the same time, the permanent magnet piece 10 is attached to the rear wall 5 of the housing.
A is provided with a gap l that is at least the same as or greater than the height of the mounting plate protrusion 14, and the rotating shaft 8 and the receiving member 7 move forward by this gap (as indicated by the arrow F).
Direction) There is promise. However, when the coil 11' is not energized, the permanent magnet piece 10 tries to get as close to the magnetic material as possible due to its magnetic force.
Since the force exerts such a force that the gap between the tapered surfaces of the permanent magnet piece and the electromagnet is minimized, the receiving member is fully pulled backward (arrow B) via the rotating shaft 8.
The protrusion is housed in the groove 15 on the back surface. Therefore, in this normal state, even if the ball collides with the side surface of the receiving member 7, the receiving member is prevented from wobbling, and the alignment between the sockets 9a and 9b and the intake port 3 is maintained well. be done.

However, as described above, when electric power I _F is supplied to the coil 11' (FIG. 8A), the permanent magnet magnetic pole 10
Based on the principle that the magnetic repulsion between a, 10b and the electromagnet magnetic poles 11a, 11b acts perpendicularly to the opposing magnetic pole surfaces, the tapered surface structure described above creates a magnetic force vector M _V (8th B) perpendicular to the tapered surface structure.
) is the vector component M that pushes the rotating shaft 8 forward
_Therefore , the permanent magnet piece 10 advances toward the rear wall of the housing, the gap l between them disappears or decreases, and the receiving member 7 advances in the F direction instead, and the space between the permanent magnet piece 10 and the mounting plate 2 is A gap l' is created, and the engagement between the protrusion 14 and the depression 15 is released.

If this happens, 5A and 6A in the previous example
As shown in the following figures, the repulsive magnetic force causes rotation of the rotating shaft 8, and as shown in figures 9A to 9C, when the permanent magnet piece 10, the rotating shaft 8, and the receiving member 7 rotate approximately 180 degrees, this time, An attractive force M _V ' is generated between the tapered surfaces that have different polarities, and since this direction is also perpendicular to the tapered surface, the permanent magnet piece 10 is rotated by one horizontal vector component M _H '. axis 8,
The receiving member 7 and the receiving member 7 are pulled rearward B and return to the position where the gap l is left between them and the rear wall 5a as in FIG. At the same time, the protrusion 15 enters the recess 14 on the side of the socket 9b to ensure that the posture is maintained again after the power is cut off.

From this state, the rotation for aligning the socket part 9a with the inlet 3 again involves the forward and backward movement of the receiving member 7 by passing a current in the opposite direction through the coil 11', as in the first embodiment. This can be done by rotating.

Of course, the protrusion 15 and depression 14 serve as stoppers.
The positional relationship may be reversed, or any shape that complementarily engages with each other may be selected.

In the above embodiment, the shape of the receiving member 7 has two sockets 9a and 9b facing each other in the diametrical direction.
In the following embodiment, a receiving member 7 having four sockets 9a to 9b arranged at 90° intervals is rotated every 90°.

First, as an electromagnetic structure for rotating the permanent magnet piece 10 together with the receiving member 7 through the rotating shaft 8 every 90 degrees, the one shown in FIG. 10 can be considered.

That is, in addition to the pair of magnetic poles 11a and 11b facing each other, there is an additional pair of magnetic poles 11 that is perpendicular to this pair.
Add c, 11d.

Initially, the permanent magnet piece 10 has its magnetic poles or both ends 10a, 10b aligned with a pair of vertical electromagnet magnetic poles 11a, 11b, and the upper magnetic pole is aligned with the N
Suppose it had become a pole. Here, permanent magnet piece 10
When rotating 90° counterclockwise R, the magnetic pole 11 is connected to the coils 11'a to 11'd of each electromagnet magnetic pole.
A current I is applied so that a and 11d become north poles, and 11b and 11c become south poles.

As a result, the opposing magnetic poles become the same polarity and repel, and at the same time, the direction of rotation thereof becomes opposite polarity.
The direction R is such that 11d (N) faces 10b (S), and the magnetic poles 11c and 11d are braked and stopped in a state where the permanent magnet piece 10 is aligned.

Next, if you want to further rotate the permanent magnet piece 10 in the R direction, in order to cause the same effect as described above, turn it counterclockwise from the magnetic pole 11a to 11d in the previous state.
NSSN was set from magnetic pole 11c to magnetic pole 11a.
Up to this point, it is sufficient to use NSSN counterclockwise, and the same applies hereafter.

The receiving member 7 that is rotated every 90 degrees in this manner can take a form as shown in FIG. 11, for example. That is, by providing socket portions 9a to 9d whose sizes change at 90° intervals and different shapes on the circumferential surface, and by selectively aligning these with the intake port 3,
Try to change the ease with which the ball enters the ball.

However, if interest is sought in the rotation of the pattern drawn on the surface of the receiving member itself, each receiving part may have the same shape.

In addition, in the quadrupole configuration shown in Fig. 10, the receiving member
It is also obvious that reciprocating rotation can only be made within a range of 90 degrees. In this case, the receiving member 7 in FIG. 11 has, for example, only socket portions 9a and 9b with a phase interval of 90°.

Furthermore, by increasing the number of poles, the receiving member can be rotated in fine rotation angle steps,
If the permanent magnet piece 10 is made into a dogleg shape, etc., it will have three poles of 120
A rotation step etc. is also possible.

Furthermore, as long as the current to the coil is not cut off after rotation, the rotor attached to the rotating shaft 8 does not have to be a permanent magnet piece 10, but is electrically conductive and rotates according to the principle of a square coil. Alternatively, a servo, motor, or step motor may be used. According to the present invention, it is possible to provide a prize-winning device with a new form change different from existing prize-winning devices, and since its rotational action is dependent on an electric electromagnetic force action,
Reliable and stable rotation can be achieved, and over-rotation of the prize-winning ball receiving member can be controlled by electromagnetic force, and it is also excellent in reliability. Moreover, the rotation of the winning ball receiving member can be controlled by detecting game balls that have entered other winning holes of the game board by the winning ball detection device and operating the electromagnetic structure based on this signal. Therefore, by controlling the operation of the electromagnetic structure using a known electrical control means such as a timer circuit, it is possible to diversify the content of the game.
