Abstract
A light adjusting apparatus includes substrates arranged in parallel, each including an opening to pass light, a rotary shaft member which is rotatable around an axis perpendicular to the substrates and movable in an axial direction, a light adjusting section fixed integrally to the rotary shaft member in a space between the substrates and configured to move to an insertion position or a retracted position along with the rotation of the rotary shaft member and adjust light that passes through the opening, and a holding member configured to restrict the rotation of the light adjusting section that moves to one substrate side in the space from the insertion/retracted position and allow the rotation of the light adjusting section that moves to the other substrate side in the space.
Claims7
A light adjusting apparatus comprising:
- a first substrate and a second substrate arranged in parallel at a predetermined distance to define a space between the first substrate and the second substrate, each of the first substrate and the second substrate including an opening formed to pass light;
- a rotary shaft member rotatable around a central axis of rotation perpendicular to the first substrate and the second substrate;
- a light adjusting section rotatably movable with the rotary shaft member, the light adjusting section being configured to move between an insertion position located in an optical path of light passing through the opening and a retracted position retracted from the optical path as the rotary shaft member rotates, to adjust and output incident light incident from the opening, the light adjusting section being configured to be movable in an axial direction of the rotary shaft member with the rotary shaft member;
- and
- a holding member configured to restrict rotation from at least one of the insertion position and the retracted position of the light adjusting section when the light adjusting section is located in a first region of the space, and allow the light adjusting section to rotate when the light adjusting section is located in a second region of the space, wherein the space is divided into the first region and the second region at different positions in the axial direction such that the first region is closer to the first substrate than the second substrate and the second region is closer to the second substrate than the first substrate.
