Title:
PACHINKO BALL PUMPING UP/POLISHING DEVICE
Document Type and Number:
Japanese Patent JP3705738
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a pachinko ball pumping up/polishing device which can simultaneously solve opposite demands which are the smooth acceptance of pachinko balls by a spiral groove, and the prevention of the generation of jamming in the spiral groove.
SOLUTION: The leading angles (A1 to 4) of the spiral groove (13) of this pachinko ball pumping up/polishing device (1) are formed in such a manner that the leading angles may become larger in steps or continuously as advancing from the lower end section in the pumping up direction. At the lower end section of the spiral groove (13) having a small leading angle, the acceptance of pachinko balls is smoothly performed. Then, since the leading angle becomes larger as advancing in the pumping up direction, a distance between the pachinko balls becomes larger, and jamming can be prevented from occurring.
