PURPOSE: A doubly clamping shutter module is provided to control lights passing through an optical instrument as a shutter blade blocks or exposes an optical passage by being rotated with a solenoid assembly. CONSTITUTION: A doubly clamping shutter module comprises a shutter blade(30), a solenoid assembly(10), a rotary central shaft, and a shutter mount(40). The shutter blade blocks and allows passage of lights by rotating at a predetermined angle around a rotary shaft(31). The solenoid assembly is composed of a solenoid(11) and a plunger(12) pushing and pulling the shutter blade so that the shutter blade is rotated forward and backward at a predetermined angle. The rotary central shaft is arranged on the rotary shaft of the shutter blade and joined to the shutter blade so that the shutter blade can be rotated. The shutter mount fixes the solenoid assembly and clamps both end portions of the rotary central shaft. |
