摘要： A camera shutter equipped with a selftimer device has an interlocking member for coordinating the movement of the camera operating member and the selftimer device to obtain accurate operation of the shutter release member. The interlocking member has a first arm which engages with the operating member during movement thereof at the beginning portion of the shutter release motion and the operating member thereafter drives the interlocking member to a position in which the interlocking member actuates the selftimer device to initiate a timing operation. Near the end of the timing operation, the selftimer device engages with a second arm of the interlocking member and thereafter drives the interlocking member to another position during the course of which a translating lever mounted on the interlocking member actuates the shutter release member to initiate release of the shutter.

摘要： The operating mechanism for a camera shutter comprises a pivoted actuating member for opening the shutter and a pivoted actuating member for closing the shutter. A driving spring for biasing each of the actuating members in actuating direction has one end acting on the respective actuating member and the other end supported by a ratchet wheel which is coaxial with respective actuating member so that the spring bias can be varied by rotary movement of the ratchet wheel. Spring finger portions of a spring plate which overlies the shutter operating mechanism engage the ratchet wheels to retain them in selected angular positions against the reaction forces of the respective springs. Portions of the spring plate support the spring fingers intermediate their attachment to the spring plate and their free ends engaging the respective ratchet wheels.

摘要： A camera shutter includes a pair of spaced apart base plates supporting the various shutter components. At least one of the base plates is formed entirely of synthetic resin material which is electrically insulative and which possesses lubricating properties. The synthetic resin base plate has a set of tubular portions extending toward and connected to the other base plate and also has a set of shafts turnably supporting some of the shutter components, such as the control lever and control cam. The synthetic resin base plate also includes a hollow winding frame about which is wound a coil and in which is slidably inserted an armature to form an electromagnet for use in controlling the shutter operation. The use of a synthetic resin base plate dispenses with the necessity of separate lubrication and enables formation of a smaller shutter.

摘要： A camera shutter mechanism for opening and closing a shutter aperture to effect an exposure comprises a group of opening blades movable, when released, from a closed position covering the shutter aperture to an open position uncovering the shutter aperture to thereby initiate an exposure, and a group of closing blades movable, when released, from an open position uncovering the shutter aperture to a closed position covering the shutter aperture to thereby terminate the exposure. A release mechanism releases the opening blades thereby enabling them to move to the open position for initiating the exposure, and subsequently releases the closing blades thereby enabling them to move to the closed position for terminating the exposure. A driving member automatically operates immediately after completion of the exposure to move the group of opening blades back towards the closed position so that the aperture is at least partially covered thereby so as to improve the light-shielding capability of the shutter mechanism.
