Claims

[Claims for Utility Model Registration] (1) A filter member mounting device for an optical machine for removably mounting a filter member disposed on the optical axis of an objective lens to a mounting portion of an optical machine main body, a filter holding frame to be held; an eccentric cam portion which is rotatably attached to the filter holding frame and has an abutment portion that can face the attachment portion of the optical machine main body; and an eccentric cam portion which is integrally attached to the eccentric cam portion. and a rotary operating section, which is operated by the rotary operating section, and presses the contact portion of the eccentric cam portion against the mounting portion of the optical machine main body to secure the filter holding frame and the optical machine main body. A filter member mounting device for an optical machine, characterized in that it is configured as follows. (2) The filter holding frame includes a holding frame portion that is attached and fixed to the optical machine main body, and a filter holder that holds the filter member and is rotatably attached to a hinge portion provided at one end of the holding frame portion. A filter member mounting device for an optical machine according to claim 1, characterized in that the device comprises: (3) The eccentric cam part and the rotation operation part shall be provided outside the optical path of the objective lens of the optical machine body, and be attached to a rotation shaft and a rotating shaft, respectively, which have axes parallel to the optical axis of the objective lens. A filter member mounting device for an optical machine according to claim 1 or 2, characterized in that: (4) The optical machine body constitutes a theodolite telescope and is rotatable around a horizontal axis, as set forth in any one of claims 1 to 3 of the claims for utility model registration. Optical machinery filter member mounting device. (5) The rotating shaft of the rotary operation part and the hinge part of the filter holding frame are respectively provided at opposing positions with the filter member of the filter holding frame interposed therebetween. 5. A filter member mounting device for an optical machine according to any one of Item 4.
