Focused image tremble correcting device

A focused image tremble correcting device comprising:

• a tremble detector that detects a focused image tremble of an optical device;
• a correcting optical system for correcting said focused image tremble, said correcting optical system being included in an imaging optical system of said optical device;
• a first driving unit that includes:
• a first rotating board which is held being rotatable around a first axis parallel to the optical axis of said correcting optical system;
• and a first driving mechanism that drives said first rotating board, said first rotating board having a first opening;
• a second driving unit that includes:
• a second rotating board which is held being rotatable around a second axis which is parallel to said optical axis;
• and a second driving mechanism that drives said second rotating board, said second rotating board having a second opening;
• and
• a controller that controls said first and second driving units to move said correcting optical system such that said image tremble can be cancelled,
• wherein said correcting optical system is supported by a first pair of inner sides of said first opening and a second pair of inner sides of said second opening,
• said first pair of inner sides being parallel to a first straight line that is perpendicular to said optical axis and said first axis,
• said second pair of inner sides being parallel to a second straight line perpendicular to said optical axis and said second axis.
