摘要： In the camera disclosed, a display device adapted for displaying photographic information and a pattern, etc., with a liquid crystal within the camera view finder, a polarizing arrangement which creates a contrast between a portion of the display and another is combined with the liquid crystal. This produces a display with a high contrast portion and a low contrast portion.

摘要： A vibration wave motor comprises a movable member friction-contacted to a vibration member, a plurality of electrostrictive element groups oppositely arranged on the opposite surfaces of the vibration member, and voltage applying means for applying voltages to the electrostrictive element groups to generate travelling vibration waves in the vibration member. The electrostrictive elements are arranged such that the electrostrictive elements oppositely arranged on the opposite surfaces of the vibration member are strained in the opposite directions when the voltages are applied thereto.

摘要： Travelling oscillation waves are generated in a lens assembly at an oscillation element by impressing a voltage to an electro-restriction element or elements, whereupon a lens driving operation is performed by frictionally driving a moving element which is pressed in contact with the oscillation element. In the case of manual operation, an oscillation ring operating as the oscillation element is separated from a rotation ring which constitutes the moving element by a clutch device and then the rotation ring is manually rotated for effecting the lens driving operation.

摘要： At least one electro-optical light shielding member is disposed close to a reticle of a photographic camera arranged for forming an image of an object to be photographed. The light shielding member is electrically controlled to have the reticle partly light-shielded by the light shielding pattern of the light shielding member in such a manner as to permit selection between an averaging light measuring mode and a spot light measuring mode.
