| 摘要 | PURPOSE: To easily adapt to an existing single-eye collimator by providing the fold type eye shielding device with a partial eye shielding means capable of controlling the shielding of an eye so as to leave a part of a center visual field without shielding it at the time of shielding and positioning the center visual field part of an eye not to be collimated and slidably supported. CONSTITUTION: When a supporting casing 19 is positioned rectangularly to a vertical tangent to the periphery of a finder 13, a partial eye shielding body 11 is arranged in the almost center visual field of an eye not to be collimated. A coupling flange 26 is projected from the fixing point of the casing 19 on the finder 13 and a supporting arm 12 is positioned on the flange 26 through a cylindrical pivot pin 28. The arm 12 is supported by the flange 26 so as to be optionally rotated around the axial line of the pin 28. The body 11 is slidably fitted to the outer end of the arm 12. Consequently the center visual field of the uncollimated eye shielded by the body 11 can be finely controlled. COPYRIGHT: (C)1989,JPO |
