に揺動し、その打玉杆（１）の打玉部（1c）でパチンコ
玉（４）を叩き、そのパチンコ玉（４）を付勢して図中
矢示方向へと飛ばしていた。First, in the one shown in FIG. 4, the ball striking rod (1) is made swingable around the reference axis (1a), and one end of the tension spring (2) is hooked on it to normally rotate it clockwise. It is given a habit of moving, and the protrusion (1b) standing on it is pressed against the cam surface (3a) of the cam (3). The cam (3) has a central shaft (3b)
The ball is rotated in the counterclockwise direction in the figure to swing the hitting rod (1). Then, when the projection (1b) drops sharply following the cam surface (3a), the ball striking rod (1) swings clockwise, and the ball striking part (1c) of the ball striking rod (1) is moved. The pachinko ball (4) was hit, and the pachinko ball (4) was urged to fly in the direction of the arrow in the figure.
次に、第５図に示すものでは、打玉杆（５）と、その打
