Abstract
An optical driving apparatus attached to an optical apparatus having a ring member that is rotatable on an outer circumference of a barrel includes a driver configured to rotate the ring member, a detector configured to detect an object that has entered a space between the optical apparatus and the optical driving apparatus, and a controller configured to control the driver in accordance with a detection of the object by the detector when the driver is rotating the ring member. The detector has a contacted portion configured to contact the object, and detects the object when the object is pressed against the contacted portion.
Claims20
An optical driving apparatus externally attachable to an optical apparatus having a lens barrel and a ring member that is rotatable on an outer circumference of the lens barrel, the optical driving apparatus comprising:
- a driver configured to rotate the ring member;
- a detector configured to detect an object that has entered a space between an outer circumference portion of the ring member and the optical driving apparatus;
- and
- a controller configured to control the driver in response to a detection of the object by the detector when the driver is rotating the ring member,
- wherein the detector has a contacted portion that extends in a first direction corresponding to an optical axis direction of the lens barrel and to which the object is contactable, and detects the object when the object presses against the contacted portion.
An optical apparatus comprising:
- a lens barrel;
- a ring member that is rotatable on an outer circumference of the lens barrel;
- and
- an optical driving apparatus externally attached to the optical apparatus,
- wherein the optical driving apparatus includes:
- a driver configured to rotate the ring member;

- wherein the detector has a contacted portion that extends in a first direction corresponding to an optical axis direction of the lens barrel and to which the object is contactable, and detects the object when the object presses against the contacted portion.
An optical driving apparatus externally attachable to an optical apparatus having a lens barrel and a ring member that is rotatable on an outer circumference of the lens barrel, the optical driving apparatus comprising:
- a driver configured to rotate the ring member;
- a first detector configured to detect an object that has entered a first space between the optical driving apparatus and a first outer circumferential portion of the ring member;
- a second detector configured to detect the object that has entered a second space between the optical driving apparatus and a second outer circumferential portion of the ring member, the first and second detectors each having a contacted portion that extends in a first direction corresponding to an optical axis direction of the lens barrel and to which the object is contactable;
- and
- a controller configured to control the driver, in response to a detection of the object by at least one of the first and second detectors when the driver is rotating the ring member, depending on a rotating direction of the ring member and on the at least one detector having detected the object.
An optical apparatus comprising:
