Ball sorter for table tennis and table tennis apparatus

在一个桌球球分拣设备中，多个导条沿桌球球桌的至少一个游戏面一侧基本上在水平方向上并排排列，其间距只允许变形的球通过，多个导条沿游戏面的后面基本上在水平方向上并排排列，其间距只允许变形的球通过。前面的导条向下游倾斜配置，而其下游侧与后面的导条的上游部分重叠，以便能够传送球。还公开了使用该桌球球分拣设备的桌球装置。 In a table tennis ball-sorting device, a plurality of rails are disposed side by side in substantially a horizontal direction along the side of at least one playing surface of a table tennis table at intervals that are capable of having passed therethrough only deformed balls, and a plurality of rails are disposed side by side in substantially a horizontal direction along the rear part of the playing surface at intervals that are capable of having passed therethrough only deformed balls. The former rails are disposed to be inclined towards downstream, while the downstream side thereof is overlapped on the upstream part of the latter rails so that balls can be transferred. A table tennis apparatus using the table tennis ball-sorting device is also disclosed.
