Claims

[Claims for Utility Model Registration] (1) At least three support members each having an aperture that includes the measurement optical axis approximately in the center and having an apex that forms one plane perpendicular to the measurement optical axis. A test lens receiving member provided around the opening, and a test lens support member (both having one test lens pressing member) for holding the test lens in a direction parallel to the measurement optical axis together with the support member. A test lens holding device for a lensmeter, characterized in that it is comprised of a test lens holding means. (2) The support member is made of a material with a low coefficient of friction, and its apex is hemispherical, and A test lens holding device for a lens meter according to claim (1) of the utility model registration claim, characterized in that the test lens holding member is a pillar member integrally molded with a test lens receiving member. (3) Pressing the test lens. Registration of a utility model characterized in that the member is composed of a pin member having a hemispherical tip and movable in a direction parallel to the measurement optical axis, and a spring means for constantly biasing the pin member in the direction. The test lens holding device for a lens meter according to claim (1) or (2). (4) The number of the pillar members is three, and the test lens pressing member is the number of the three pillar members. Three pin members having apexes in a plane parallel to a plane passing through each tip of the pillar member, and the apex of the pillar member and the pin member do not come into contact with each other. A test lens holding device for a lensmeter according to claim (3) of the utility model registration claim, characterized in that the supporting member is a pillar installed in the test lens receiving member. A test lens holding device for a lens meter as described in claim (1) of claim 1, characterized in that the pillar member has a ball member rotatably held at its tip. .
