に順次打ち込んで行くようになっている。When manufacturing the game board 1 for a ball-and-ball game machine, it is essential to perform a nailing operation in which nails 3 are driven one by one into predetermined positions of the game board 1. Conventionally, there is a nailing machine as described in Japanese Patent Publication No. 2-35587. This automatic nailing machine mounts a game board 1 on a mounting table, fixes the same, and moves the mounting table back and forth, right and left along the board surface of the game board 1, and moves the nail supplied to the nail gripping means. 3 is sequentially driven into a predetermined position of the game board 1.

いる。On the other hand, as an automatic nail adjuster for adjusting the angle of the nail 3 after being driven into the game board 1, conventionally, an actual nail 2-1 has been used.
No. 11,483, and the like. In this automatic nail adjusting machine, the game board 1 after nailing is fixed on a mounting table, and the nail adjusting holder is engaged with the head of the nail 3,
The angle of the nail 3 is appropriately adjusted by relatively moving the game board 1 and the nail adjustment holder in accordance with the adjustment direction.

になる。As described above, 200 to 300 nails 3 are arranged on the board of the game board 1, and each of the nails 3 falls from the upper portion of the game board 1. It is important to make the moving direction of the ball change, and to determine the probability that the game ball will win the winning means 4, 7, 8, 9, 10, etc.,
In particular, the angle and interval of about twenty or more nails 3a located on the entrance side of game parts such as winning means 4, 7, 8, 9, 10, etc., are very important.

よる機械的作業により調整する方法を採っている。That is, the nails 3a located on the entrance side of the game parts such as the winning means 4, 7, 8, 9, 10, etc. are generally called life nails. , 8, 9, 10, etc., are very important in determining the probability of a game ball winning. However, the conventional automatic nailing machine merely drives nails 3 sequentially into predetermined positions of the game board 1 at an upward angle of about 5 °. For this reason, conventionally, an automatic nailing machine
After hitting 3, about 20 or more nails 3a will be the life nails
Is adjusted in a separate process by manual work by an operator or mechanical work by an automatic nail adjuster.

釘打ち機を提供することを目的とする。Therefore, conventionally, not only in the case of manual operation by an operator but also in the case of mechanical operation by an automatic nail adjuster, the nailing operation and the nail adjustment operation by the automatic nailer are performed in separate processes. Since the operation is performed, there is a disadvantage that the operation efficiency is significantly reduced. When trying to automate by machine,
Despite having to adjust only about 20 or more nails, it is necessary to provide an automatic nailing machine in addition to the automatic nailing machine, and it is necessary to secure a large space for installing the automatic nailing machine, Equipment costs will increase significantly. SUMMARY OF THE INVENTION In view of such a conventional problem, the present invention can adjust a nail at any time during a nailing operation, as needed, and can perform a nailing operation and a nail adjusting operation simultaneously and efficiently and quickly. An object of the present invention is to provide a nailing machine for a ball game machine.
