Abstract
PURPOSE: To make possible an interesting pachinko game while harmonizing a pachinko parlor's benefit and players' benefit by providing a probability control member for controlling the probability of a struck ball entering a special winning port of a central winning apparatus. CONSTITUTION: General winning ports 16, 16 opening toward the front are provided to the right and left of a special winning port 15. Probability control members 17 are disposed to the right and left of the special winning port 15. The probability control member 17 comprises projecting support shafts 21, 21 rotatably planted to the right and left above the special winning port 15 with a vertical member 23 with its lower end having an ornament portion 22 secured to the fore-end of each of the support shafts 21. A ball sorting member 24 is provided at the upper end of the vertical member 23 to be generally parallel to the support shaft 21. A drive shaft 25 projecting backward from the vertical member 23 is brought into pressing contact with a generally elliptic cam 26 located on the back side of an attachment base plate 8 by means of a spring 27. The cam 26 is rotated by operating a motor 28. The rear end portion of the drive shaft 25 is pressed with the major diameter portion of the cam 26. As the cam 26 is rotated, the distance between right and left ball sorting members 24, 24 is increased and decreased so that the probability of balls entering the special winning port 15 is controlled.
