摘要： Disclosed is a magnetically controlled focal plane shutter wherein one electromagnet controls a leading shutter curtain and another electromagnet controls a following shutter curtain by releasing respective checking members as power is supplied thereto. The electromagnetic characteristics of the electromagnet that controls the following shutter curtain differ from those of the electromagnet controlling the leading shutter curtain. According to a specific embodiment disclosed, the follower-curtain controlling electromagnet saturates earlier than the leading curtain controlling magnet so as to compensate for deterioration of an energizing battery and thereby limits the problem of shutter time lag resulting from the long battery use.

摘要： An electromagnetic driving device for driving shutter blades wherein a field coil used as stator encircles a permanent magnet rotor and extends across the rotational axis thereof. The rotor is arranged to undergo reciprocating rotation through less than one half turn in driving the shutter blades to open and close the shutter. Interference between the field coil and a coaxially arranged output shaft is avoided by the provision of a U-shaped intermediate member extending about the field coil and connecting the output shaft and the rotor.

摘要： A brake device for use with a shutter having a driving member which runs down when the shutter is opened or closed, includes a brake member pivotally rotatable about a stationary shaft and arranged upon engagement with the shutter driving member to slow it down and bring it to rest. An elastic material is employed in forming at least one of the above-described brake member and stationary shaft to effect a frictional engagement therebetween which contributes to the braking of the shutter driving member.

摘要： A filter element, including a pair of filter plates that are each made of a nonwoven fabric or felt of a polymeric material shaped into a plate having a corrugated cross section and which are positioned in such a way that the grooves in one filter plate are opposed to those in the other filter plate, is reinforced with reinforcements that are placed across the width of the filter element. The reinforcements and the filter element are secured at their respective ends by means of bolts. The reinforcements are similar in cross-sectional shape so that they can circumscribe the corrugated cross section of the filter plates such that a pair of the reinforcements can hold the filter element therebetween.

摘要： A focal plane shutter adapted for use in a single lens reflex camera and having front and rear curtains with respective charge control gears to be operated in engagement with each other during the winding process. At the terminal end of one cycle of winding operation, these gears are released from positive connection with a film winding mechanism, while the front and rear curtains are held in their cocked positions by separate latches in at least a time interval between a moment at which the diaphragm starts to move and a moment at which the mirror flips out of way to actuate release of the front curtain, thereby an electromagnetic release control for the rear curtain latch is prevented from being disturbed as by a shock which would be otherwise exerted on the rear curtain latch at the start of movement of the front curtain.
