[0002]

2. Description of the Related Art The contents and configuration of the prior art will be described with reference to FIGS. FIG. 6 is a schematic view of a main part configuration of an example of an electric ball hitting device that has been frequently used in the related art. In this example, an electric motor 4 is used as a drive source, and an output shaft 4-1 of the electric motor 4 is used.
And a transmission pin 8-3 provided at the tip of an arm 8-2 integrally formed with the hammer 1 playing the game ball 19 and rotatably supported by the shaft 3 and fixed to the cam 20 fixed to the arm 20. For the game ball 1 continuously with the rotation of the output shaft 4-1 of the electric motor 4.
9 is played. In this example, the repelling force and the restoring force of the hammer 1 are provided so as to be adjustable by the adjusting knob 18 and the spring member 17 connected to the adjusting knob 18. However, these components are all mechanically linked, and There were problems such as complicated arrangement, vibration from the motor 4 side, and impact from the hammer 1 being transmitted directly to each other, thereby affecting the installation environment of the gaming machine.

[0003] To solve the above-mentioned problems, Japanese Patent Application No. 61-2
As you can see in 20964 and Jikken 63-129995,
The inventor of the present application has proposed a configuration in which the driving side and the driven side have a non-contact structure. 7 and 8 are schematic diagrams illustrating an example of the configuration with reference to FIG. Although the details are omitted, the connecting means between the driving side and the driven side is constituted by two permanent magnets 5 and 6 which are magnetized to the same number of poles and arranged so as to face each other. As means for adjusting the coupling force between the permanent magnets 5, 6, a shielding member 10 made of a magnetic material is inserted into and removed from the gap 9 between the permanent magnets 5, 6.

[0004] Although the above-mentioned non-contact structure has been able to realize the effects expected in the first place, such as simplification of the mechanism, operability, reliability, and suppression of transmission of vibration and shock. ,
In the initial assembling process of the electric hitting device, it is necessary to adjust the gap between the two permanent magnets 5 and 6, which has a large influence on the entire device, that is, the gap 9 between the two permanent magnets, as a measure against the variation in the magnetic characteristics of the permanent magnets used. For example, it is necessary to add a semi-fixed preliminary adjustment mechanism as a solution to these problems.

[0005]

The conventional structure as described above has solved the problems in terms of stabilizing the resilience and suppressing the transmission of vibration and shock as an electric ball hitting device, but at a low cost. Since there was a problem in the adjustment of "fly" due to variations in accuracy and characteristics of many parts to be procured, it was necessary to add means for completing a hitting device in which the adjustment of "fly" was easy.

[0006]

Means for Solving the Problems An electric ball hitting device for a game according to the present invention is made of a magnetic material and enters into a gap between a driving side and a driven side permanent magnet in conjunction with a handle operation of a player. A first shielding member, which is provided so as to be detachable and includes a shielding portion and an arm portion that enter the gap, and is also made of a magnetic material,
At a position different from the first magnetic shielding member, together with a second shielding member provided to be able to enter and leave the game ball in advance for the installer to perform a jump adjustment operation of the game ball, in the vicinity of the second shielding member, A third shielding member which is made of a magnetic material and is provided so as to be able to enter the gap in order to adjust in advance the variation of the magnetic performance of the disk-shaped permanent magnet facing the surface by the installer; And a latch that is movable inside the case and a pressing spring that presses the latch are provided, and the column is fixed and held by the pressure contact between the uneven surface of the latch and the inner wall of the case. ,
Alternatively, a small gear fixed to the rotor shaft of the electric motor and a large gear on the back side of the driven permanent magnet are linked by a timing belt, or the small gear is rotatably supported by a ball bearing mounted on a case. It is configured to be held on the rotor shaft via a flexible coupling member provided.

[0007]

[Operation] In the above-described configuration, while solving problems such as stabilization of resilience and suppression of transmission of vibration and impact as an electric ball hitting device, many components to be procured at low cost are covered. There is an effect of adding a means for completing the apparatus by absorbing variations in accuracy and characteristics.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 5 shows two permanent magnets 5 facing each other as described above.
6 is a schematic diagram illustrating a state in which a shielding member 10 provided as a coupling force adjusting means of a non-contact connection structure 6 is inserted into and removed from a gap 9. FIG. 1 is a schematic front view of a first embodiment according to the present invention relating to the arrangement of the shield member 10 in the air gap 9 looking at one permanent magnet side, and a first magnetic shield member 10-1 operated by a player. And a second magnetic shielding member 10-2 previously adjusted and operated by a trader to adjust the "flying" of the game ball 9. The first shielding member 10-1 has a substantially arc-shaped shielding portion 10-11 inserted into the gap and an arm portion 10-12 serving as an insertion / removal means. The arm portion 10-12 has A rack 10-13 is formed on the side surface thereof, and is movably arranged by a pinion 11 which engages with the rack.

A second shielding member 10-2 is provided at another position of the above-mentioned gap 9, and as described above, this attracts the two permanent magnets 5, 6 facing each other prior to the operation of the player. That is, the coupling force is adjusted to adjust the "flying" of the game ball 19, and a mechanism for adjusting and holding the second shielding member 10-2 is formed inside the case 1 as shown in FIG. 4, for example. A pillar 10-21 fixed to the second shielding member 10-2 by providing a latch 12 and a pressing spring 13 in the space 1-1.
Is pressed and held, and the position in the gap 9 is adjusted by moving the column 10-21 exposed through the elongated slide hole 1-2 of the case 1.

FIG. 2 shows another example of the present invention.
Third shielding member 1 in addition to the shielding members 10-1 and 10-2 of FIG.
0-3 are additionally provided. The third shielding member 10-3 is for adjusting the variation in the magnetic performance of the permanent magnets 5 and 6 facing each other and constituting the non-contact coupling.
By making the attraction force, that is, the coupling force, of the two permanent magnets constant in the completed state of the ball hitting device, the trader "flying".
This facilitates adjustment work. In this example, there is no change in the function of the first shielding member 10-1 operated by the player or the second shielding member 10-2 adjusted by the trader in advance.

In the first and second examples described above, the drive-side permanent magnet 5 is mounted on the output shaft 4-1 of the motor 4 having the speed reduction mechanism reduced to a predetermined number of revolutions. In a configuration in which the main body and the speed reduction mechanism are integrated, the length in the axial direction is large, and in some cases, it has not been possible to cope with recent demands for thinning. As a means for realizing the reduction in thickness, as shown in FIG. 3, the rotor shaft 4-1 of the electric motor 4 and the shaft 3 of the operation handle are arranged in a non-coaxial position side by side and fixed to both shafts and the large gear 1 and the large gear 1.
A configuration in which the extension in the axial direction is suppressed by being connected by the timing belt 14 and the timing belt 14 is also effective. Even in this configuration, there is no change in the function and effect due to the addition of the shielding member. However, in order to realize compactness and low cost, it is required to reduce the size of the electric motor 4 and relax the accuracy of the mechanical members. Contributes to the adverse effect on the motor 4 itself due to the direct transmission of vibrations and shocks due to the operation of the ball hitting device on the load side to the motor 4.
It is also effective to connect the motor and the rotor shaft of the electric motor 4 via a flexible member.

[0012]

Since the electric hitting device according to the present invention has the above-described configuration, it can solve the problems in terms of stabilizing the resilience and suppressing the transmission of vibration and impact as an electric hitting device. At the same time, there is an effect of adding a means for completing the apparatus by absorbing variations in accuracy and characteristics of many parts to be procured at low cost.
