TABLE TENNIS BALL SELECTOR DEVICE AND TABLE TENNIS DEVICE

摘要

PROBLEM TO BE SOLVED: To keep playing a table tennis always under normal conditions and to facilitate device maintenance. SOLUTION: A plurality of rails 321 are roughly horizontally arranged in parallel along the side of at least one court 14 on a table 10 at intervals such that only deformed balls can pass, and a plurality of rails 331 are roughly horizontally arranged in parallel along the rear of one court 14 at intervals such that only deformed balls can pass. The plurality of rails 321 on the side are inclined downstream, with their respective downstream ends arranged on the upstream parts of the rails 331 at the rear in such a manner that balls can be transferred between them, the downstream ends of the rear rails 331 being tilted downstream; balls rolling downstream on the rails 331 at the rear further roll on rear rails 352, 362, so that only normal balls are returned toward a ball shooting part by a ball dip up means 38.
