摘要:
An adjustable rotary shutter for a movie camera comprises a rotary shutter (2) and a shutter-adjusting wing (4) which can be adjusted coaxially with respect to said shutter and which is connected via a gear with an adjusting motor (3) coupled to the shaft (1) of the rotary shutter (2). A detector device arranged between the shutter-adjusting wing (4) and the shaft (1) of the rotary shutter or the rotary shutter itself (2) emits a signal which corresponds to the position of the shutter-adjusting wing (4) relative to the shaft (1) of the rotary shutter or the rotary shutter (2).

A lens module (100) including a base (110), a lens (120), a front cover (130), a first shielding plate set (140), a second shielding plate set (150), and a gasket (160) is provided. The lens is disposed on the base. The front cover is rotatably disposed above the base and the lens, and the front cover has a first through hole (131). Each of the first shielding plate set and the second shielding plate set is pivoted on the base. The second shielding plate set and the first shielding plate set interfere with each other. The gasket is fixed in the first through hole and coupled to the second shielding plate set. The gasket has a second through hole (162). When the base and the front cover rotate relative to each other, the gasket rotates with the front cover and drives the first shielding plate set and the second shielding plate set to limitedly swing.

A camera may comprise a lens assembly to receive optical information from a subject and a shutter assembly comprising a blade, a base plate to pivotally support the blade, and a wire to move the blade in response to a current. The camera may include an image sensor to selectively record optical information passing through the shutter.
摘要:
The invention relates to a method and a device for detecting the opening angle of the shutter (light or dark sector) of an adjustable rotating shutter (1) arranged in a film camera. Said shutter comprises a circular-segment-shaped or circular-sector shaped shutter wing (2) which is driven by a shutter motor via a shutter shaft (20), and also comprises an adjustable shutter adjustment wing (3) arranged in a coaxial manner in relation to the shutter wing (2) and which can be displaced in relation to said shutter wing by means of a shutter adjustment wing motor (33). According to the invention, the position of the shutter wing (2) and the position of the shutter adjustment wing (3) are detected during a rotation of the rotating shutter (1) and the difference between the two positions forms a value for the shutter opening angle or the light or dark sector of the rotating shutter (1).

La présente invention se rapporte à un dispositif d'obturation pour le contrôle de précision d'un flux, comprenant au moins un organe d'obturation (1) d'une section (3) de passage du flux, dont le mouvement est proportionnel à celui d'un actionneur (6) qui le commande, caractérisé en ce que ledit dispositif comprend au moins deux organes d'obturation (O1,O2) commandés par l'actionneur (6) au moyen d'une transmission (4) permettant d'obtenir des coefficients de proportionnalité légèrement différents pour le mouvement desdits organes.
摘要:
A shutter system for a movie camera (10) or the like for controlling the film exposure including a main shutter wheel (110) rotatably mounted on main drive shaft (140) driven by a first motor (144) and at least one adjustable shutter wheel (120) positioned adjacent to and coaxially rotating with the main shutter wheel, the adjustable shutter wheel being mounted on a secondary shaft (160) independently driven by a second motor (164). Both the aperture (determined by the relative positions of the shutter wheels of the main shutter wheel and adjustable shutter wheel) and the shutter speed are set by a controller (170) which regulates the speed of each of the motors.
