Abstract
An optical apparatus includes a lens movably supported, a driving part arranged to rotate for causing the lens to move, a moving mechanism arranged to cause the lens to move by the rotation of the driving part, and an adjusting mechanism arranged to cause the moving mechanism to move the lens for fine adjustment by applying rotational driving to the moving mechanism without recourse to the driving part.
Claims21
An optical apparatus, comprising:
- a holding member for holding an optical element;
- driving means;
- a moving mechanism for moving said holding member by said driving means;
- and
- an adjusting mechanism for adjusting the position of said holding member by using said moving mechanism and not using said driving means, said adjusting by said adjusting mechanism being an adjustment during the assembling of said holding member.
2 more elements
An optical apparatus, comprising:
- a first fixing member;
- a rotational operation member for moving an optical element, said operation member being connectable to said first fixing member by rotation;
- and
- a second fixing member connectable to said rotational operation member by rotation,
- wherein said first and second fixing members are mutually fixed relative to the rotation direction of the rotational operation member by inserting one of said first and second fixing members into the other member and said rotational operation member is rotatable in the rotation direction relative to said first and second fixing members.
2 more elements
An optical apparatus, comprising:
- a holding member for holding a lens;
- driving means having an arm portion fixable to said holding member and rotatable so as to rotate said holding member;
- means for converting the rotation of said holding member into the movement in the optical axis direction of said holding member;
- and
- an adjusting mechanism for rotating said holding member so to change the rotating position of said holding member relative to said arm portion.
