An upper plate is installed on an upper part of the cylinder movably in a horizontal direction. A male screw part(13) is formed on an exterior of the cylinder. The fixing plate is fixed on a fixing base(2) of a receiving rest of a cassette by coupling a bolt through hole of the fixing plate and a bolt fixing hole(2a) of the fixing base with a bolt. The cylinder is inserted and fixed inside the fixing plate. The position fixing unit fixes the position of the cylinder and is installed on the fixing plate by fixing the male screw part of the cylinder and a female screw part of the fixing plate.
