A conventional ball-and-ball game machine employs a structure in which an operation arm made of a metal wire is used, and the operation arm operates a ball feed means via a relay arm. When the position of the ball feeding means changes up and down due to opening and closing, or when the ball sending means becomes clogged with game balls, bites by foreign substances, etc. and becomes inoperable, the operating arm is elastic. By deforming,
The launching operation of the launching means is enabled, and damage to the relay arm, the ball feed means and the like due to the launching operation of the launching means is prevented. However, in the conventional structure, the operation arm is formed by bending a metal wire, and the entire operation arm is elastically deformed. Therefore, it is very difficult to determine how much elastic force is used for the metal wire. is there.

Therefore, if a metal wire that is not easily elastically deformed is used for the operating arm, the following problem occurs. That is, when the vertical position of the ball feeding means is proper and the ball feeding means is normal and there is no clogging or the like, the ball feeding means can be reliably operated in conjunction with the hitting hammer. When the ball falls below the proper position, or when the ball feeding means becomes clogged with game balls, the operating arm does not deform sufficiently and the ball feeding means is forced through the relay arm. Since the relay arm is operated, there is a problem that the relay arm is broken or the movable portion of the ball feeding means is damaged and cannot be recovered. The present invention has been made in view of the above-mentioned conventional problems, and in normal operation, the ball feeding means can operate smoothly and reliably in conjunction with the hitting hammer, and when abnormal, damage to the ball feeding means side can be prevented beforehand, and the structure is simple. An object of the present invention is to provide a ball game machine that can be easily and inexpensively implemented.

In the ball game machine having the above structure, when the firing motor 21 is operated by operating the firing handle 9, the cam body 22 is operated.
Rotates around the rotation shaft 26 in the direction indicated by the arrow a, and rotates the hammer 10 against the tension spring 20 in the direction indicated by the arrow b around the pivot shaft 24 as shown in FIG. When the cam body 22 is disengaged from the cam roller 28 of the hammer 10, the hammer 10 urged by the tension spring 20 rotates around the support shaft 17 in the direction indicated by the arrow b, and fires as shown in FIG. The game ball located on the firing position A of the rail 11 is hit and fired toward the guide rail.

On the other hand, each time the hammer 10 hits and fires a game ball on the firing rail 11, the operating arm 30 and the relay arm 31
The ball feeding means 12 operates in conjunction with the hitting hammer 10 via the, and the ball feeding means 12 supplies the game balls from the upper plate 6 one by one to the firing position A on the firing rail 11.

That is, on the ball feeding means 12 side, the ball feeding member 15 usually descends due to the weight of the receiving member 16 side, and the regulating portion 15a regulates the game ball on the upper plate 6 side. Further, the relay arm 31 is in an L-shaped state in which the first arm 33 and the second arm 35 are urged in the anti-refraction direction by a helical spring 36, and are pivotally supported by a pivot 37. I have. At this time, since the relay arm 31 has its center of gravity below the pivot 37, as shown in FIG. 3, the first arm 33 side hangs downward from the pivot 37, and the second arm 35 side is the ball feeding means 12. It is located below.

Therefore, when the hammer 10 is driven by the cam body 22 to rotate around the pivot 24 in the direction indicated by the arrow b, the hammer 10
When the operating arm 30 rotates in the direction indicated by the arrow b, the bent portion 32 of the operating arm 30 comes into contact with the first arm 33 of the relay arm 31 and the hammer 10 moves in the direction indicated by the arrow b. With the rotation, the relay arm 31 is rotated around the pivot 37 in the direction indicated by the arrow c.

The first arm 33 of the relay arm 31 is c
When rotated in the direction indicated by the arrow, the first arm 33 and the second arm 35 are normally rotated integrally, and the operation portion 41 is moved by the ball feeding means.
12 is pushed up, so that the receiving member 16
The ball feed member 15 is rotated upward and pushed up. As a result, the ball feeding member 15 rises, and the regulating portion 15a is displaced upward from the game ball, so that the game ball regulated by the regulating portion 15a falls from the ball sending member 15 onto the receiving member 16. However, at this point, the relay arm 31 is rotated in the direction of the arrow c to push up the receiving member 16, and the receiving member 16 receives the game ball in the ball feed case 14, so that the game ball is fired. It is not supplied on the rail 11.

When the cam body 22 is disengaged from the cam roller 28 of the hammer 10, the hammer 10 is rotated around the pivot shaft 24 in the direction indicated by the arrow b by the tension spring 20, and the game ball on the firing rail 11 is moved. The firing arm 30 is fired toward the guide rail side, and the operating arm 30 is returned integrally with the hammer 10 in the direction indicated by the arrow b.
The pivot 31 rotates around the pivot 37 in the direction indicated by the arrow c, and the pushing of the receiving member 16 by the operating section 41 is released.

For this reason, after the receiving member 16 rotates in the descending direction around the support shaft 17 and the hitting hammer 10 hits the game ball on the firing rail 11, the game ball on the receiving member 16 is released from the shooting rail 11.
Supply on top. Hereinafter, in the same manner, the player
9 as long as the motor mounting plate 21 is actuated and the cam body 22 is rotated, the hitting hammer 10 sequentially fires game balls on the firing rail 11 and fires after the game balls are fired. The supply operation of supplying the next game ball onto the rail 11 is sequentially repeated.

When the vertical position of the ball feed means 12 is slightly lower, when the hammer 10 rotates around the pivot shaft 24 in the direction indicated by the arrow b, the operating arm 30 and the hammer 10 It rotates together and pushes up the receiving member 16 of the ball feeding means 12 via the relay arm 31, so that the receiving member 16 and the ball feeding member 15 are raised as described above. Then, during operation of the relay arm 31 by the operating arm 30, the receiving member 16 is raised to the upper limit, and the relay arm 31 and the ball feeding means 12 side are locked, so that the second arm portion 35 side of the relay arm 31 is pivoted. It becomes impossible to rotate in the direction of arrow c around 37.

However, at this time, the first arm portion 33 of the relay arm 31 rotates around the pivot shaft 39 against the helical spring 36 in FIG.
, The first arm portion 33 and the second arm portion 35 are bent, and the operation arm 30 is allowed to rotate. After that, when the cam body 22 passes through the cam roller 28, the first arm 33 is pivotally mounted on the pivot shaft 39 by the urging force of the helical spring 36.
While rotating in the direction indicated by the arrow d around, the entire relay arm 31 returns and rotates in the direction indicated by the arrow c around the pivot shaft 37, so that the receiving member 16 and the like of the ball feeding means 12 descend as described above. Then, the next ball feeding means 12 is supplied onto the firing rail 11.

Therefore, even when a positional abnormality such as the ball feeding means 12 being lower than the proper position occurs, the relay arm 31,
Damage to the ball feeding means 12 including the receiving member 16 and the like can be prevented beforehand, and the ball feeding means 12 can be reliably operated. If for some reason an abnormality such as a game ball biting into the ball feeding means 12 or clogging of foreign matter occurs, the receiving member 16 remains lowered to the lowered position in FIG. Even when pushed up by the relay arm 31, it is difficult to ascend from the lowered position.

In this state, the hammer 10 and the operating arm 30 rotate around the pivot 24 in the direction indicated by the arrow b. However, the receiving member 16
Is locked in the lowered position in FIG. 8, and the relay arm 31 is
Since the first arm 33 and the second arm 35 of the relay arm 31 cannot be rotated around the pivot shaft 39 in the same manner as described above, the rotation of the hammer 10 is allowed. Then, damage to the ball feeding means 12 from the relay arm 31 is prevented.

That is, if the second arm 35 side of the relay arm 31 cannot rotate at the position shown in FIG. 8, the hammer 10 rotates in the direction indicated by the arrow b, and the operating arm 30 moves to the first arm 33. When the first arm 33 abuts against the helical spring 36, the first arm 33 pivots about the pivot shaft 39 in the direction of the arrow d against the helical spring 36, and the first arm 33 and the second arm 35 Bend. Therefore, even if the ball feeding means 12 is operated in conjunction with the hitting hammer 10 of the launching means 8 and an abnormality such as biting of a game ball occurs on the ball feeding means 12 side, the relay arm is also provided. Damage to the ball feeding means 12 including the receiving member 16 and the receiving member 16 can be prevented.

There is an advantage that the first arm portion 33 can be operated by the operating arm 30 as in the normal operation.

The present invention is not limited to the embodiment. For example, in the embodiment, the operating arm 30 may be formed of a synthetic resin material in addition to the metal wire. Further, in the first embodiment, a pivotally attached cylindrical portion 44 is provided on the protruding portion 43,
Although the first arm 33 has the pivot shaft 39, the first arm 33 may have the pivot tube 44 and the projection 43 may have the pivot shaft 39. In the first embodiment, the pivot portion is constituted by the pivot shaft 39 and the pivot tube portion 44, but a structure other than this may be adopted. Further, as the urging means, a tension spring may be used instead of the helical spring.
