There is one that supplies the game balls from the game ball supply tray one by one to the launch position on the launch rail by means.

The firing means includes a hammer that is rotatable about a fixed shaft, a spring that urges the hammer in the striking direction, and a firing motor that drives the hammer around the fixed shaft against the spring. After the hammer is driven by the firing motor, the hammer is rotated in the striking direction by the spring, and the gaming ball at the launch position is struck by this hammer to be launched to the guide rail side. .

On the other hand, the ball feeding means is provided with a ball feeding member which is swingable around a support shaft, and this ball feeding member is adapted to be interlocked with a hammer with an operating rod. That is, an operating rod made of a metal wire rod is used, the base of this operating rod is fixed to a striking mallet, and at the tip side thereof, an engaging portion that abuts the ball feeding member of the ball feeding means is bent to form a striking mallet. The engaging portion of the operating rod operates the ball feeding member of the ball feeding means in conjunction with the rotation of the.

[0005]

In this type of game ball supply apparatus, the ball feed means is made long because the engaging portion of the operating rod is brought into contact with the ball feed member and the ball feed member is interlocked with the hammer. When used over a period of time, there is a drawback that the contact point between the ball feed member and the operating rod, especially, the contact point on the ball feed member side is extremely damaged.

In addition, since the engaging portion of the operating rod is brought into contact with the ball feeding member and the ball feeding member is interlocked with the hammer, the ball feeding means is operated smoothly and surely in conjunction with the hammer. Therefore, it is necessary to completely match the strokes of the contact portions of the operating rod after the engaging portion of the operating rod comes into contact with the ball feeding member. However, it is very difficult to make the engaging portion of the operating rod and the stroke on the side of the ball feeding member completely coincide with each other, and thus it is difficult to expect a smooth and reliable operation of the ball feeding means.

In particular, since the contact point of the operating rod on the side of the ball feeding member is greatly damaged, if it is used for a long period of time, backlash due to wear of the contact point or the like occurs and the ball feeding means is damaged. There is the drawback that smooth and reliable operation cannot be guaranteed. Further, since the engaging portion of the operating rod is brought into contact with the ball feeding member and the ball feeding member is interlocked with the hammer, a contact sound is generated between the engaging portion of the operating rod and the ball feeding member, There is also a drawback that the contact noise becomes louder as the damage at the contact point progresses.

In view of the above conventional problems, the present invention can smoothly and smoothly interlock the ball feeding member side of the ball feeding means with a hammer and prevent damages, noises and the like due to mechanical contact. An object of the present invention is to provide a game ball supply device for a ball game machine in which the ball feeding means can be operated smoothly and reliably without being affected by the stroke between the hitting hammer side and the ball feeding member side.

Can be freely reciprocated left and right within the range. Each stopper 70,71
Are provided on the rear wall 47 of the first case body 34, respectively.

In the above structure, when playing a game,
After putting the game ball B in the upper plate 12, when the firing handle 17 of the firing means 16 is grasped and operated to a predetermined angle, the firing means 16
The ball feeding means 13 operates in conjunction with the launching operation of the game ball B, and sequentially supplies the game balls B in the upper plate 12 one by one to the launch position A of the launch rail 14 to supply and launch the game ball B. Repeat alternately.

That is, when the firing motor 17 is operated by operating the firing handle 17, the cam body 23 fixed to the rotating shaft 21 thereof is operated.
Rotates in the direction of the arrow d, and hits the hammer 18 via the cam roller 22.
Drive. For this reason, the hammer 18 rotates around the fixed shaft 8 in the direction of the arrow c while resisting the spring 19 to tension the spring 19. When the cam body 23 is disengaged from the cam roller 22, the striking mallet 18 is rotated around the fixed shaft 8 in the direction of the arrow e by the pulling force of the spring 19, and the mallet at the tip of the striking mallet 18 launches the firing position on the launch rail 14. Hit A's game ball B and launch rail 14
Fire along the guide rail 11 side.

On the other hand, while the striking mallet 18 is being driven by the cam body 23 of the firing motor 20, the permanent magnet of the operating member 25 of this striking mallet 18 is driven.
As shown by the phantom lines in FIG. 2, 29,67 are separated from the ball feeding member 33, and repulsive force is not generated between the permanent magnets 29,67. Support shaft
It is in the return position where it rotates about 32 times and comes into contact with the first stopper 70. That is, the ball receiving portion 59 of the ball feeding member 33 is the ball holding portion.
It corresponds to the lower side of 37. Therefore, the sphere holder 37
The game ball B inside is fitted in the ball receiving portion 59 and is supported from below.

When the striking mallet 18 is rotated in the direction of arrow e from this state, as shown in FIG. 2, the permanent magnets 29,67 on the operating member 25 side approach the permanent magnets 29,67 on the driven member 57 side. Therefore, a repulsive force is generated between the permanent magnets 29 and 67, and the hammer 18
The ball feed member 33 is connected to the support shaft 32 in conjunction with the rotation of the e in the arrow direction.
Rotate around in the direction of arrow b. At this time, the game ball B fitted in the ball receiving portion 59 of the ball feeding member 33 is fed from the ball holding portion 37 to the ball guiding portion 52 side by the rotation of the ball feeding member 33 in the ball feeding case 31. Go.

Then, the hammer 18 is rotated to the striking position, the permanent magnets 29,67 of the actuating member 25 reach the straight line connecting the fixed shaft 8 and the support shaft 32, and the permanent magnets 29,67 The repulsive force causes the ball feeding member 33 to come into contact with the second stopper 71. Therefore, the game ball at the launch position A of the launch rail 14
At the same time as hitting B, the ball receiving portion 59 of the ball feeding member 33 corresponds to the ball guiding portion 52 as shown in FIG. 3, and the game ball B of the ball receiving portion 59 moves backward along the inclination of the receiving surface. It rolls and falls to the side of the ball guide 52, and the game ball B is dropped from the ball guide 52 through the ball outlet 51 onto the launch rail 14. Therefore, the next game ball B can be fed onto the launch rail 14 after the game ball B has been launched.

On the other hand, if the ball feeding member 33 is in the rotating position,
As shown in FIG. 3, the ball support part 58 of the ball feed member 33 corresponds to the lower side of the ball holding part 37, and after sending the game ball B fitted in the ball receiving part 59, from the ball entrance 36 to the ball holding part. The next game ball B coming into 37 is supported from below by the ball support portion 58 and held.
At this time, the ball pressure of the succeeding game ball B in the alignment portion 12a of the upper plate 12 is applied to the ball support portion 58 side of the ball feed member 33.

However, the ball feed member 33 is provided with a support boss 55 which is long in the front and rear, and supports the support boss 55 rotatably by the support shaft 32, while the center of the support boss 55 is slightly forward. Since the plate-like portion 56 is integrally projected, and the reinforcing ribs are provided on the side of the ball-supporting portion 58 of the plate-like portion 56, this ball-feeding member is provided.

It is possible to reliably prevent the ball feeding member 33 from being deformed to the rear side of the ball support portion 58 and the like, and the game ball B being loaded in the ball holding portion 37.

Further, the repulsive force of the two permanent magnets 29, 67 is used to interlock with the rotation of the striking mallet 18 in the firing direction to bring the ball feeding member 33 to the rotation position where it abuts against the second stopper 71. Since the is being rotated, the striking mallet 18 side has rotated too much at this time,
It is only necessary that the different poles of the two permanent magnets 29, 67 correspond to each other so that an attractive force is generated, and therefore it is not necessary to exactly match the rotational strokes of the hammer 18 and the ball feed member 33. .

After the striking mallet 18 has launched the game ball B at the launch position A of the launch rail 14, the cam body 23 on the launch motor 20 side again contacts the cam roller 22 and starts driving the striking mallet 18, 18 rotates rapidly around the fixed shaft 8 in the direction of arrow c against the spring 19. Therefore, the permanent magnet on the operating member 25 side
Since 29,67 are suddenly separated from the permanent magnets 29,67 on the driven member 57 side of the ball feeding member 33 in the rotating position, both permanent magnets 2
The repulsive force is not generated between 9,67, and the ball feeding member 33 returns to the return position by the gravity of the weight 65 as shown in FIG.

With the ball support portion 58 supporting the game ball B in the holding portion from the lower side, the ball feed member 33 is returned and rotated around the support shaft 32, and the ball feed member 33 is moved to the first stopper 70. When contacting and rotating to the return position, the game ball B on the ball support portion 58 is disengaged from the ball support portion 58 in the ball holding portion 37 and the ball receiving portion.
It drops to 59. Then, the game ball B fitted in the ball receiving portion 59 in the ball holding portion 37 is supported from below by the receiving surface. At this time, the next game ball B is the ball holding part from the ball entrance 36.
It is only slightly inside 37, and the ball holding portion 37 and the ball receiving portion 59 receive the ball pressure of the following game ball B.

Then, the batting mallet 18 is rotated in the batting direction around the fixed shaft 8 by the urging force of the spring 19, and the game ball at the launch position A is reached.
While striking and firing B, the repulsive force between the permanent magnets 29, 67 causes the ball feeding member 33 to rotate around the support shaft 32, and the game ball B in the ball receiving portion 59 is fired after the launch rail 14 Send it to firing position A above. In the same manner, the ball feeding means 13 operates in the same manner as the firing operation of the firing means 16, and the firing operation and the supply operation are sequentially repeated.

The ball feeding case 31 of the ball feeding means 13 is divided into a first case body 34 and a second case body 35, and the ball feeding member 33 is interposed between the both case bodies, and both cases are separated. Unite the body. At this time, the three fitting cylinder portions 48 of the first case body 34 and the three boss portions 55 of the second case body 35 are fitted and coupled. By fitting the fitting tubular portion 48 and the boss portion 55 in this manner, the relative positions of the two case bodies can be reliably positioned. Further, since the fitting tubular portion 48 and the boss portion 55 are fitted together, the fitting tubular portion 48 and the boss portion 55 are arranged by easily selecting a position that does not interfere with the ball feeding member 33 and the like in the ball feeding case 31. it can.
