PURPOSE: To execute the testing and sorting work of capsules automatically and continuously by forming an air-pressure hole for exhausting air to extrude a capsule passing through a capsule gauge from a gauge hole on the capsule gauge.

CONSTITUTION: The inlet part of a guide gauge 2 is cut off obliquely, so that a capsule can be guided to the guide gaude hole. A testing gauge 4 is arranged on the outlet side of the guide gauge 2 and the testing gauge 4 consists of a limitation gauge 4a and a pressed air gauge 4b having the air-pressure hole for injecting air to the periphery of the capsule and extruding the capsule to the limitation gauge 4a. Thus, the testing and sorting work of capsules can be performed automatically and continuously.
