摘要： A vibration wave motor for generating a travelling vibration wave in a vibration member by applying a periodic voltage to an electro-mechanical energy transducer. An anti-movement device is provided to contact the vibration member at a pitch not equal to a multiple of n.lambda./2, where n is an integer and .lambda. is the wavelength of a vibration wave so that the vibration member is prevented from rotating without reducing the drive efficiency of the motor.

摘要： A filter mounting mechanism capable of attachment to and detachment from an optical assembly such as the interchangeable lens assembly of a single lens reflex camera is provided with a holding member arranged to rotatably carry a filter in such a manner that the filter may be rotated from externally of the optical assembly in order to enable adjustment of the filter. The mechanism includes a device for preventing the filter from becoming loosened while in use and the arrangement further operates to facilitate use of a thin film filter such as a gelatin filter in cases where such a filter is to be used by preparation and cutting thereof into a desired size and shape.

摘要： A focus presetting mechanism for a camera lens assembly including an annular member fitted on the outer diameter of the lens assembly and rotatable relative thereto about the optical axis thereof which may be clamped at a fixed angular position in order to establish a predetermined focusing point at which the focusing ring of the lens assembly may be stopped. Stop members operatively interposed between the annular member and the focusing ring enable the focusing ring to be repeatedly returned to a predetermined focused position when the annular member is maintained clamped at this position.
