The input is supplied to the input unit of the unit 33. In response to the nail driving end signal, the control unit 3
3 instructs the nail holder mechanism 1 and the hammer mechanism 20 to start retreating from the nail driving position L2 of the holder base 2 to the nail receiving position L1 and start raising the hammer head 21.

In order to drive one nail 37 into a game board 31 mounted on a nailing machine 30 for manufacturing a game machine according to this embodiment, a predetermined position of the game board 31 is set by the nail holder mechanism 1 and the hammer mechanism 20. After the positioning is stopped downward, one nail 37 is supplied from the nail supply unit 36 to the nail holder mechanism 1.
The mutual operation of the nail holder mechanism 1 and the hammer head 21 up to the step of driving into the nail will be described with reference to FIGS. 1 and 3 to 6.

First, as shown in FIG. 1, when a predetermined position of the game board 31 is stopped, the nail holders 3e and 4d
7, the nail holder mechanism 1 is waiting at the nail receiving position L1 so as to be coaxial with the nail receiving position L1 of the hammer 22.
The hammer head 21 is stopped at the standby position at the nail driving position L2 so that the hammer head 21 is coaxial with the nail driving position L2.
In the nail receiving position L1, in the nail holder mechanism 1, the arm stopper 7b is pushed into the stopper receiving hole 4a, and the movable arm 4 cannot be opened and closed with respect to the fixed arm 3 by receiving the opening force of the arm spring 6. Is fixed. Thereby, as shown in FIG. 3, the nail holder 3e of the fixed arm 3 and the nail holder 4d of the movable arm 4
Are in a closed state where an inscribed circle L can be drawn.

Next, as shown in FIG.
7 is lowered and pushed down by a pusher (not shown) of the nail supply unit 36 (see FIG. 6), so that the nail 37 is moved between the nail holding unit 3 e of the fixed arm 3 and the nail holding unit 4 d of the movable arm 4. To be inserted and mounted. The holding force of the nail holding portions 3e, 4d is such that the shaft portion 37a of the nail 37 pushed down by the pusher can slide down with respect to the nail holding portions 3e, 4d, and at the same time, the nail holding portion 3 is attached to the shaft portion 37a.
e and 4d are adjusted to an appropriate force that does not cause abrasion. Then, after a lapse of time from the start of the nail supply operation in the nail supply unit 36 until the nail 37 is inserted and mounted in the nail holding units 3e and 4d, the control unit 33 moves the nail holder mechanism 1 from the nail receiving position L1 in the direction of arrow A. To move forward. The elapsed time from the start of the nail supply operation to the holding of the nail is a time previously set in a design stage when the nailing machine 30 for manufacturing a game machine is manufactured.

Thereafter, as shown in FIG. 5, when the nail holder mechanism 1 reaches the nail driving position L2 from the nail receiving position L1, the control unit 33 stops the movement of the nail holder mechanism 1. Due to this stop, the nail 37 held by the nail holder mechanism 1 and the hammer 22 become coaxial, and the release lever 7e
The projection 7f and the plunger 23 are coaxial. Then, the control unit 33 starts lowering the hammer head 21. During this lowering, the receiving recess 22a of the hammer 22 takes in the head 37b of the nail 37 and pushes it down. By this pressing down, the spiral part 3 is moved from the tip of the nail 37.
The portion up to the shaft portion 37a after 7c is driven into a predetermined position of the game board 31.

Therefore, the axis of the nail 37 and the axis of the hammer 22 are aligned vertically, and a linear force acts on the nail 37 from the upper side to the lower side from the hammer 22 to play the game normally without buckling the nail 37. It can be driven into the board 31. Then, immediately before the nail 37 is driven into the game board 31 by a predetermined amount, the plunger 23 pushes down the projection 7f of the release lever 7e.
As a result, the release lever 7e rotates downward about the shaft 7d, and the shaft 7d rotates together with the rotation of the release lever 7e. As a result, the arm stopper 7 of the seesaw 7a is rotated.
The side b is the shaft 7d against the spring force of the seesaw spring 7g.
And the arm stopper 7b is pulled out from the stopper receiving hole 4a.

Then, as shown in FIG. 6, due to the spring force of the arm spring 6, the distal end of the movable arm 4 moves in a direction away from the distal end of the fixed arm 3 to the outside of the center of the fixed arm 3 around the pin 8. open. And the head 37b of the nail 37
When the descent of the hammer head 21 is stopped immediately before the hammer head 21 comes into contact with the nail holder arm 5, the position sensor 25 acts on the sensed member 24 and outputs a nail driving end signal to the control unit 33. In response to the nail driving end signal, the control unit 33 causes the nail holder mechanism 1 to retreat in the arrow B direction from the nail driving position L2. In the initial stage of the retraction of the nail holder mechanism 1, the protrusion 7 f of the release lever 7 e is set by setting the front and rear widths of the protrusion 7 f of the release lever 7 e and the front and rear width of the plunger 23.
When the movable arm 4 is retracted without interfering with the nail 37 while the movable arm 4 is open and retracts to a position where the movable arm 4 comes off from the nail 37, the release lever is released. The projection 7f of 7e comes off the plunger 23. Thereafter, the control unit 33 raises the hammer head 21.

Thereafter, the nail holder mechanism 1 moves the nail driving position L
The control unit 33 reaches the nail receiving position L1 from
Stops the movement of the nail holder mechanism 1. Due to this stop, the nail holder mechanism 1 waits for the downward supply of the nail 37 from the nail supply unit 36. Thereby, the game board 31 of one nail 37
The nailing into the is completed. Further, the control unit 33 controls the game board 31 according to the next nailing position and order based on the nailing data.
3 to 6 are repeated after the table 32 on which is mounted is moved vertically and horizontally within the plane to position and stop the predetermined position of the game board 31 below the nail holder mechanism 1 and the hammer mechanism 20.

In the above-described embodiment, the table 32 is moved in the XY directions in a plane to position and stop the predetermined position of the game board 31 below the nail holder mechanism 1. However, the table 32 is kept stationary and the nail holder mechanism is stopped. 1 and hammer mechanism 20
