2. Description of the Related Art Conventionally, as a safe ball receiver of this type, for example, as shown in FIG. 9, a pair of movable blades 102, 102 are erected and tilted on both front sides of a ball inlet 101 provided in a mounting plate 100. It is freely pivoted, a box frame 103 is provided on the rear surface of the mounting plate 100, and a plurality of ball contact pieces 104 are formed in the box frame 103 at equal intervals. Rotating body 106 having mating walls 105, 105
And a lever piece 108 that swings by receiving a sphere entering from a sphere introduction port 107 formed on the upper surface of the rear part of the box frame 103, and the sphere passing between the movable wing pieces 102, 102 is a sphere contact piece 104.
The rotating body 106 is rotated by an angle of 360 degrees / number of ball contact pieces by contacting the movable wing pieces 102,
When the engaging walls 105, 105 intervene between the 102, the movable wing pieces 102, 102 stand up and the engaging walls 105, 105
The movable wing piece 10 is made to tilt in a portion where there is no
When the movable blades 1 and 2 are in the upright state, the rotation of the rotating body is caused also by the swing of the lever piece 108, and the movable wing piece 1 is moved.
A device in which 02 and 102 are tilted is known.

By the way, in such a conventional safe ball receiver, a ball passing between the movable wing pieces 102 and 102 and flowing out to the rear of the box frame 103 comes into contact with any one of the plurality of ball contact pieces 104. Each time the rotating body 106 is rotated through an angle of 360 degrees / number of ball contact pieces, the movable blades 102, 102 are rotated.
Therefore, if the number of the ball contact pieces 104 is increased, the number of tilts of the movable wing pieces can be increased accordingly, which is more interesting for the player.

Therefore, the present applicant has already proposed a safe ball receiver which can dramatically increase the number of times of tilting of the movable wing piece without significantly changing the design of the conventional safe ball receiver. As shown in FIG. 10, a rotation angle regulating plate 109 is provided in a sphere passage through which a sphere passing between the movable wing pieces 102 and 102 flows backward from the box frame 103, and the rotation angle regulating plate 109 makes contact with the rotating body 106 to make a predetermined movement. After the sphere is rotated by the angle of, the movable wing pieces 102, 102 are erected once and opened five times (open five times) so as to surely separate from the rotor 106. Has proposed a safe ball receiver (Japanese Patent Application No. 3-357904).

[0005]

However, in the conventional multi-fold safe ball receiver, the rotating body 106 is contacted by balls.
Since the rotation angle of the rotating body 106 is small, for example, when a strong rotating force is applied to the rotating body 106 due to the swinging of the lever piece 108, the rotating body 106 cannot rotate excessively and stop at the correct stop angle. It was hard to be satisfied with.

An object of the present invention is to reliably prevent the excessive rotation of the rotating body so that the function of the safe ball receiver with a large number of openings can be properly maintained.

[0007]

Inside the box frame provided on the rear surface, a plurality of recessed portions are formed on the outer periphery at equal intervals, and the rotating body is provided with engaging pieces at both outer sides of the required recessed portion, and the rear top surface of the box frame. And a lever piece that swings by a sphere that enters from the sphere introduction port formed in the above.
The rotary blades are rotated by an angle corresponding to the number of the concave portions, and when the engaging pieces intervene between the movable blade pieces, the movable blade pieces are erected so that the movable blade pieces can be tilted at a portion where there is no engaging piece. In a safe ball receiver in which the rotation of the rotating body is caused by the swing of the lever piece when the piece is upright, a stopper is provided on the side surface of the rotating body, and the stopper swings the lever piece. Then, when the movable wing piece that has stood upright is tilted, the movable wing piece is provided at a position where it can abut the lever piece in the oscillating state.

[0008]

With the movable wing piece standing upright, when the sphere enters from the sphere introduction port on the rear upper surface of the box frame and the lever piece oscillates, the oscillating lever piece causes the rotor to rotate 360 degrees / concave concave portion. Rotate a number of angles. At this time, even if the rotating body rotates excessively, its stopper comes into contact with the lever piece in the swinging state to stop the rotating body at the correct stop angle.
