Abstract: A camera shutter has a set of opening blades and a set of closing blades sequentially driven from cocked positions to released positions to effect an exposure. During cocking of the shutter, the opening and closing blades are driven to their cocked positions by opening and closing mechanisms which include springs for permitting continued movement of the opening and closing mechanisms in the cocking direction after the opening and closing blades are driven to their cocked positions. Upon completion of the movement of the opening and closing blades to their cocked positions, the springs undergo further compression thereby permitting continued cocking movement of the opening and closing mechanisms independent of the opening and closing blades.

Abstract: In the present invention, stopping-down, sector preliminary closure and lens shutter release are effected in association with an interlocking member of the lens. The difference between the amount of operation of the interlocking member effected when a camera with an electronic eye, hereinafter an EE control mechanism is operated is obtained by varying the amount of operation of the interlocking member, regardless of the pressure or absence of EE control provided by the EE control mechanism. The use and non-use of the lens shutter is switched depending on this difference. The relating means between the camera and the lens is substantially identical to the relating means between an ordinary interchangeable lens not having a lens shutter and an automatic aperture. Therefore, for switching between the lens shutter use and non-use, it is unnecessary to provide an additional relating means between the lens and the camera. If the lens shutter is not used, the lens can be used in the same manner as if it was an ordinarily interchangeable lens.Furthermore, in the present invention, the shutter speed of a focal plane shutter is switched to a constant speed in association with the switching operation to use the lens shutter. Therefore, unlike the case where a conventional focal plane single lens reflex camera and an interchangeable lens with a lens shutter are employed, it is unnecessary in the present invention to switch the shutter speed of the focal plane shutter to a constant speed separately when the lens shutter is used. The associated switching of the present invention is foolproof, and contributes to an improvement in operation.

Abstract: An optical apparatus in which a beam of light is caused to travel along a predetermined direction is provided with a light interrupter for interrupting the beam. The light interrupter includes a light-interrupting component, such as a shutter blade or color filter, and a driving coil connected to the light-interrupting component. The light-interrupting component and driving coil are mounted for pivotal movement about an axis substantially parallel to the beam direction, with the light-interrupting component moving between a light blocking position and an unblocking position. A control circuit is connected to the driving coil for effecting energization of the coil. A magnet arrangement is so positioned as to establish a magnetic field through which the driving coil moves when the driving coil pivots around the pivot axis, with the magnetic field being oriented substantially perpendicular to the direction of movement of the driving coil.

Abstract: A leading blind and a trailing blind are made of rigid material such as metal sheet and each is provided with at least one permanent magnet. Along the path of the blinds are arranged electromagnetic coils. Each magnet mounted on the blind has a brush which is in slidable contact with the contacts connected with the electromagnetic coils. The magnet on the blind and the electromagnetic coils arranged in a line along the path of the blind constitute a linear motor to drive the blind. The coils are connected with an exposure control circuit and are energized to drive the blind. The leading blind is driven upon depression of a shutter release button and the trailing blind is driven when a time determined by the exposure control circuit has lapsed. In a preferred embodiment of the invention, the blind is divided into a driving blade and a follower blade to save the space occupied by the blind.

Abstract: The disclosure relates to a forward-reverse film transport synchronizing mechanism for a motion picture projector film feed apparatus of the type including a shuttle which is driven for vertical reciprocating motion by a transport cam. The mechanism of the present invention includes a rotary shutter which is driven by a rotating shaft and includes a pair of drive lugs arcuately spaced by 180.degree. and axially spaced from one another. A transport cam drive means coupled to the transport cam and including a driven lug which is selectably engageable with one or the other drive lugs causes the transport cam to rotate when the rotating shaft rotates. Because the driven lug is selectably engageable with either of the drive lugs, the angular relation of the transport cam relative to the rotary shutter may be varied by 180.degree. thus providing properly synchronized forward and reverse film transportation without requiring reversal of the angular direction of rotation of the rotating shaft.
