Ball sorter for table tennis and table tennis apparatus

Abstract

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.

Description

technical field [0001] The present invention relates to a table tennis ball-sorting device and a table tennis ball-sorting device comprising the ball-sorting device. Background technique [0002] Hitherto, there has been proposed a table tennis device such as that disclosed in Japanese Utility Model Registration No. 3017687. This conventional billiards device comprises a ball table with a net drawn in its center, a ball serving portion configured at the rear of a game surface (the game surface on one side of the machine), which turns the billiard balls to the other side (the game surface on the player side) successively. ) is issued, wherein a plurality of optical sensors with light emitting elements and light receiving elements are relatively arranged on the left and right sides along the radial direction of the game surface of the machine, and the balls returned by the player are detected by these optical sensors on the game surface of the machine side. Drop position, and...

AI Technical Summary

Problems solved by technology

[0004] However, according to the above-mentioned conventional billiards device, the defective ball that falls on the player's foot by mistake and thus deformed by stepping on it is also collected and returned to the serving part, and is sent out after a fixed time delay from the serving part, so that it may affect the game (training) normal progress

In addition, since the player cannot continue the game when the number of defective balls mixed in the teeing portion increases, the defective balls must be picked out manually at regular intervals, complicating the maintenance of the device.
