Abstract: One or more optical slits of a variable optical slit assembly limit the widths of optical beams propagating through the optical slits. A frame assembly of the variable optical slit assembly operatively couples one or more encoded translators to the optical slits. In operation, rotations of the encoded translators alter the widths and/or positions of the optical slits.

Abstract: A shutter intended for use with a light-sensitive material. The shutter includes a light-blocking disk having a light-passing portion through which light can pass to reach a light-sensitive material. The disk is rotated to locate its light-passing portion in line with the light-sensitive material to allow light passing through the light-passing portion to advance towards the light-sensitive material. The shutter also includes a capping element which is moved between a light-blocking position and a non-light-blocking position relative to the light-sensitive material and the light-passing portion of the disk. A single sensor is used to detect a predetermined rotational position of the disk and in response thereto the capping element is moved from one of its light-blocking and non-light-blocking positions to the other.

Abstract: A camera comprises an exposure aperture, a shutter blade supported for pivotal movement from a covering position over the exposure aperture to an uncovering position removed from the exposure aperture and having an indentation along an edge of the shutter blade, and a striker movable within the indentation in a forward direction against one portion of the edge to pivot the shutter blade from its covering position to its uncovering position. The striker is movable in the forward direction out of the indentation when the shutter blade is pivoted to its uncovering position, in order to allow the shutter blade to be returned to its covering position, and is movable in a reverse direction to return to the indentation when the shutter blade is in its covering position. Another portion of the edge faces the one portion of the edge within the indentation to contact the striker in the indentation, in order to prevent the shutter blade from being dislodged from its covering position due to a physical shock to the shutter blade.

Abstract: A microceramic electromagnetic light shutter is disclosed including a unitary ceramic body having an internal cavity. A conductive coil is formed in the internal cavity. The unitary ceramic body defines a first and second bearing structure on it's surface. The unitary ceramic body has a light aperture and first and second recesses. The microceramic electromagnetic light shutter further includes a shutter drive mechanism including a shutter blade and a ferromagnetic element inserted into the first recess and operative to the shutter drive mechanism for applying a torque to the shutter drive mechanism which causes the shutter drive mechanism to move so that the shutter blade is in it's light blocking position. The shutter drive mechanism is mounted in the second recess an in an operative relationship to the coil and ferromagnetic element. The shutter blade is movable between a light blocking and light passing positions relative to the light aperture so that when a drive voltage is applied to the coil a field is created by the coil which provides a torque to the shutter drive mechanism to overcome the torque applied by the ferromagnetic element thereby causing the shutter blade to move to the light passing position. When the drive voltage is discontinued the ferromagnetic element provides a torque on the shutter mechanism causing the shutter blade to return to the light blocking position.

Abstract: A caulking pin joint for use with a light shielding blade in a shutter or aperture mechanism of a camera. The caulking pin has a disc-shaped head, a circular protrusion depending therefrom, and a hollow-circular segment depending from the circular protrusion. The actuation arm of the shutter or aperture rests on the head, while the light shielding blade rests on the circular protrusion. The hollow circular section is then spread outward so as to rotatably secure the actuator arm to the light shielding blade. The interior surface of the hollow circular section is chamfered such that when it is folded over on top of the light shielding blade, it presents only a small smooth protuberance from the light shielding blade. This allows a second light shielding blade to be positioned close to the first light shielding blade without fear of collisions or interference between the blades. The circular protrusion upon which the light shielding blade rests, may be provided with a surface inclined up to and including 15.degree. for receiving the light shielding blade. A punch and dye is used to deform both the hollow section and the periphery of the insertion hole in the light shielding blade.

Abstract: Aperture correction for a moving aperture shutter comprising a first aperture, a second larger aperture, and a mechanism for causing relative movement between the first and second apertures between an initial position where the first and second apertures are out of registry, through an intermediate position where the first aperture is partially within the second aperture and an exposure position where the first aperture is within the second aperture, and wherein the aperture correction is provided by altering a physical relationship between the first and second apertures so as to minimize the amount of exposure of the second aperture during movement through the intermediate position. The shape and/or size of the second aperture can be altered, the location of the first aperture within the second aperture in the exposure position can be altered, or there can be a combined alteration of aperture shape, size and location. As a result, the foregoing counters the blur circle elongation of the moving aperture shutter.

Abstract: A continuous taking camera has eight exposure chambers arranged in two horizontal rows and four vertical columns. One 35 mm full size original frames of photographic film is divided into eight sub-frames. One taking lens is disposed in front of each of the exposure chambers. A stationary shutter plate is disposed behind the taking lenses. Openings are formed in the stationary plate behind the respective lenses. First and second shutter disks are rotatably supported coaxially on the stationary plate on a single shaft. A first group of two holes is formed in the first disk. A second group of two holes is formed in the second disk. The second disk is rotated by the rotation of the first disk, there being a pin-and-slot lost motion connection between the two disks, so that different sets of holes in the disk register with each other, depending on the direction of rotation of the disks. Thus, the holes of the groups are either in registry with or displaced from each other, in accordance with a direction of rotation of the disks. When the holes are in registry and the disks are rotated, they open/close the eight stationary openings sequentially. The disks are actuable through one complete cycle of movement to take sequential scenes on the eight sub-frames.
