摘要： A first blade is made up of two arms and three blades supported by the arms, wherein one of the arms is rotated in the clockwise direction by a driving pin pressing a pressed portion thereof only when a first-blade driving member is rotated by the force from a driving spring, and the other arm is reciprocally rotated by an output pin fit to a slot when a motor is reciprocally rotated. A second blade is made up of two arms and three blades supported by the arms, wherein one of the arms is reciprocally rotated by a driving pin fit to a slot when a second-blade driving member is reciprocally rotated. One of two action methods can be selected by determining a driving sequence for the first-blade driving member and the motor as to the first blade. Thus, the present invention provides a focal-plane shutter for a digital still camera which can take a picture with both the normally-open method and the normally-closed method.

摘要： A first blade actuating member and a second blade actuating member have pins, respectively. A movable contact member, which is urged to rotate in a counterclockwise direction, has locking arms and a contact piece member. When the first blade actuating member is rotated in the counterclockwise direction in photographing, the movable contact member causes a locking arm of to follow a pin of the first blade actuating member and causes the contact piece portion to come into contact with the contact piece portion of a stationary contact portion to thereby detect an abnormal actuation of the first blade actuating member by offset from normal timing. Next, when the second blade actuating member is rotated in the counterclockwise direction, a locking arm of the movable contact member is rotated by being pressed by a pin and causes the contact piece portion thereof to come into contact with the contact piece portion of the stationary contact portion to thereby detects an abnormal actuation of the second blade actuating member, similarly to the above mentioned.

摘要： A focal-plane shutter comprises a shutter plate having a shutter opening, opening blades and closing blades for opening and closing the shutter opening, and arms connected by connector portions to the opening and closing blades for driving the blades parallel to the shutter opening to effect an exposure. Resilient stopping members are disposed to make resilient contact with the opening blades at opening positions thereof where the opening blades are retracted from the shutter opening, and other resilient stopping members are disposed to make resilient contact with the closing blades at closing positions thereof where the closing blades close the shutter opening. The resilient stopping members are positioned on opposite sides of the connector portions so that when the blades strike the stopping members, reaction forces are produced which cancel each other out thereby preventing excessive wear of the connector portions.

摘要： A light-shielding blade material is provided that contributes to increased focal plane shutter speeds. A focal plane shutter has a front blade group and a rear blade group, each being composed of a plurality of light-shielding blades. At least one of these light-shielding blades is made of a Be-Al alloy material containing 40% by weight or more of Be, and has a thickness of 40 to 150 microns. This light-shielding blade is light in weight and high in stiffness, thereby significantly contributing the increased focal plane shutter speeds.

摘要： A focal-plane shutter for cameras is constructed so that the second blade group is placed in a blade chamber on the shutter base plate side and the first blade group is placed in a blade chamber on the auxiliary base plate side. The auxiliary base plate is placed on the image sensor side in a camera and secures projecting members, each having a spherical convex portion whose surface is palladium-plated. In the first blade group, five blades are pivotally supported by two arms, and immediately before, at least, a joint shank for pivotally supporting a slit-forming blade is moved inside the aperture for exposure of the auxiliary base plate during operation and reaches a position corresponding to the edge of the aperture, the arm strikes on the projecting member and is shifted to the object side so that the head of the joint shank does not abut against the edge of the aperture. Consequently, it is avoidable that the head of the joint shank abuts against the edge of the aperture to produce wear dust.
