Claims

[Scope of Claim for Utility Model Registration] (1) A contact lens inspection holder for setting a contact lens in a prescribed inspection optical instrument while the contact lens is held tightly between a pair of clamping arms of a contact lens holder. A base portion attached to the optical instrument; an inspection light transmission hole provided vertically through the base portion; and a test light transmitting hole extending horizontally on the upper surface side of the base portion. A pair of clamping arms of the contact lens holder, which are disposed opposite to each other with a transmission hole in between, cooperate with each other to hold the contact lens holder, guide the contact lens holder in a horizontal direction, and hold the contact lens holder in a horizontal direction. A holder for contact lens inspection, comprising a pair of guide groove means that can be set above the inspection light transmission hole while being held between a pair of holding arms of the holder. (2) The inspection light transmission hole is a through hole, and the base part is connected to the through hole with respect to a cylindrical base part mounting part provided on the adapter for setting the base part in the optical instrument. The through hole is configured to be inserted into the adapter and set in the optical instrument, and to prevent the base attachment part of the adapter from protruding from the upper surface of the base part in the attached state of the base part. Claim (1) characterized in that the length dimension or cross-sectional shape is set.
). (3) When the contact lens held in the contact lens holder guided in the horizontal direction by the guide groove means reaches above the inspection light transmission hole, further movement of the contact lens holder is prevented. Claim (1) having movement preventing means
Or the holder described in (2). (4) The movement blocking means is a protrusion projecting into the guide groove means or a partition defining an end of the guide groove means, and the pair of clamping arms abut against such protrusion or partition. According to
4. The holder according to claim 3, wherein a movement position of the contact lens holder guided by the guide groove means is defined. (5) The movement preventing means is constituted by a predetermined portion of the contact lens holder other than the pair of clamping arms or a contact portion against which a member integrally assembled with the contact lens holder comes into contact, and such contact portion 4. The holder according to claim 3, wherein the movement position of the contact lens holder guided by the guide groove means is determined by contact with the guide groove means. (6) When the contact lens held by the contact lens holder is moved onto the inspection light transmission hole by movement of the contact lens holder, the contact lens holder is moved between the pair of clamping arms of the contact lens holder. Any one of claims (1) to (5), further comprising a lens positioning means that comes into contact with an edge of the contact lens in the moving direction to substantially align the center of the contact lens with the center of the inspection light transmission hole. Holder described in Crab. (7) The lens positioning means is removably attached to the base part, and by replacing the lens positioning means, the contact lens can be adjusted relative to the lens positioning means according to the diameter of the contact lens. 7. The holder according to claim 6, wherein the abutment position is adjustable.
