Image stabilizing apparatus, optical apparatus using image stabilizing apparatus, and driving apparatus

An optical apparatus using an image stabilizing apparatus comprising:

• the optical element;
• a first fixing member;
• a movable member holding the optical element, and movably supported in a flat surface perpendicular to an optical axis;
• a ball sandwiched between the movable member and the first fixing member;
• a vibrator including a piezoelectric element and a vibrating plate, and moving the movable member;
• a slider contacting the vibrating plate, and provided in the movable member;
• a spring pressurizing the vibrating plate against the slider;
• and
• a second fixing member fixed to the first fixing member so as to make the vibrating plate and the slider contact each other with a predetermined pressure.

A driving apparatus, comprising:

• a fixing member;
• a movable member movable with respect to the fixing member;
• a plurality of vibrators including a piezoelectric element and a vibrating plate;
• and
• a plurality of support members arranged between the movable member and the fixing member, and movably supporting the movable member with respect to the fixing member,
• wherein the movable member is moved with respect to the fixing member by vibrating at least one of the plurality of vibrators,
• the plurality of vibrators are arranged in a flat surface parallel to the moving direction of the movable member, and
• the plurality of support members are arranged between a surface on the opposite side of a side of the movable member corresponding to the plurality of vibrators and the fixing member.
