    摘要: In a driving mechanism of an optical device that communicates the motive power generated at a drive source to an object to be driven by employing a plurality of gears, the plurality of gears are each constituted by using, at least, one of; polyester, polyamide and polyacetals. The plurality of gears include a gear having a low bending elastic modulus set to 10 kgf/mm2 or higher and 100 kgf/mm2 or lower and a gear having a high bending elastic modulus set to 50 kgf/mm2 or higher and 1000 kgf/mm2 or lower that meshes with the gear having the low bending elastic modulus, and thus, it becomes possible to reduce the noise generated at the gear meshing portion without compromising the durability of the gears.

    摘要: A focal plane shutter provides an extremely durable and reliable super-high speed shutter with speeds of greater than 1/8000 second which minimizes increases in the charge energy, has an increased rate of acceptance of the FRP and is economical to produce. The blades will not collide with or be damaged by the intermediate plate and the light shielding plate, even when the shutter is released while accelerating the camera in a direction virtually perpendicular to the direction of movement of the blades. The focal plane shutter includes a front and a rear blind that each include multiple dividing blades. The rigidity of the slit-forming blades having the largest amount of movement among the dividing blades differs between the front blind and the rear blind.

    摘要: The present invention aims at improving the durability of a very high-speed shutter exceeding 1/8000 sec and further attaining a very high shutter speed even with sectors composed of a material exhibiting a low rigidity. For this purpose, a focal plane shutter device comprises: first and second blinds each constructed of a plurality of sectors; and a light shielding plate having an opening and an intermediate plate disposed between the first blind and the second blind. The first and second blinds are run in the facial direction of the light shielding plate so as to cover and expose the opening. The light shielding plate and the intermediate plate are bonded, or a shock absorbing member is interposed between these two plates.
