摘要： 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.
摘要翻译：用于照相机的快门或光圈机构中的遮光片的铆接销接头。铆接销具有圆盘形的头部，从其延伸的圆形突出部以及从圆形突出部垂下的中空圆形部分。快门或孔的致动臂位于头部上，而遮光叶片搁置在圆形突出部上。然后将中空圆形部分向外展开，以将致动器臂可旋转地固定到遮光叶片上。中空圆形部分的内表面被倒角，使得当其在遮光片的顶部折叠时，其仅具有来自遮光片的小的平滑突起。这允许第二遮光叶片定位成靠近第一遮光片，而不用担心叶片之间的碰撞或干扰。光屏蔽叶片所在的圆形突起可以设置有倾斜并且包括15°的表面，用于接收遮光片。使用冲头和染料使遮光片中的插入孔的中空部分和周边变形。

摘要： A blade type focal plane shutter is designed to decrease the shutter charge energy and to improve the durability of the shutter without decreasing the impact resistance of the main arms of the shutter. The shutter may comprise a shutter base plate having an aperture; shutter blades each composed of a plural number of blade segments and a driving mechanism having main arms and follower arms rotatably connected to the shutter base plate and blade segments as to form a parallel link mechanism, the main arms having pin-receiving holes in which driving pins are engaged respectively. Through the driving pins, the driving mechanism is able to move the blade segments between the aperture opening position in which the blade segments are folded up outside the aperture and the aperture closing position in which the blade segments are expanded to cover the aperture. The follower arms are decreased in rigidity and/or impact resistance or in thickness relative to the main arms.

摘要： In the focal plane shutter having front and rear curtains disposed between lens and film on the camera, each of the front and rear curtains has a plurality of divided blades, and the shutter performs exposure to the film by forming a slit of a predetermined width between edge surfaces opposed to each other of the front and rear curtains, each of the divided blades comprises a light-reflective lens-side surface and a light-reflective slit-side edge surface having respective predetermined rates of diffused reflection. The lens-side surface is formed to have a rate of diffused reflection in a range of 7 to 30% within the region of visible light, as the predetermined rate of diffused reflection. The slit-side edge surface is formed to have a low rate of diffused reflection of not greater than 15% within the region of visible light, as the predetermined rate of diffused reflection. With this divided blades, the rate of reflection of the surface of the shutter curtain is applicable to a rate of reflection that enables TTL multi-pattern light adjustment and also unevenness of exposure is prevented from occurring.

摘要： A focal plane shutter device which, regardless of the number of times of operation, does not lose precision of operation. The shutter device has bend portions disposed in drive arms which drive shutter blades. The convex portions of the bend portions (ridge portions) face an adjacent shutter baseplate side. These bend portions reduce or eliminate friction as between caulking pins connecting blades to the drive arms, thereby increasing reliability.

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： According to one aspect of the present invention, a focal plane shutter of a camera for conducting TTL multi-pattern light adjustment is provided that comprises a plurality of shielding blades for covering an aperture in a developed position. Each of the shielding blades has at least one edge thereof overlapped by one of the shielding blades immediately adjacent thereto in the developed position, the overlapped edge having a predetermined minimum overlap width. Each of the shielding blades has the lens-side surface thereof formed to be light-reflective having a rate of diffused reflection. The rate of diffused reflection is set within a range according to the predetermined minimum overlap width, such that TTL multi-pattern exposure is enabled and light leakage between the shielding blades does not occur.
