ABSTRACT:
A test tube cap removing apparatus includes a fixing unit that holds a test tube having an opening portion that is closed by a cap. A hold unit is situated above the cap in an axial direction of the test tube, has a position that is variable relative to the test tube in the axial direction, and is capable of contacting a top portion of the cap. A clamp unit is provided on the hold unit, supports the cap at side surfaces of the cap in a case where the hold unit is put in contact with the top portion of the cap, and removes the cap from the test tube in a case where the hold unit moves upwards relative to the test tube in the axial direction.
