摘要： A focal plane shutter has at least one shutter blade group comprised of a leading blade and a set of trailing blades. A first parallel link mechanism is pivotally connected at two spaced locations to the leading blade to effect displacement of the leading blade relative to a shutter opening. A second parallel link mechanism is pivotally connected at two or more spaced locations to the set of trailing blades to effect displacement of the trailing blades relative to the shutter opening. The distance between the two pivotal connections of the first parallel link mechanism is greater than the distance between the at least two pivotal connections of the second parallel link mechanism.

摘要： A focal plane shutter for a camera comprises opening and closing blade units operable to open and close a shutter opening of the camera. Each blade unit has a leading blade and trailing blades in superposed relation to the leading blade. The leading blade and the trailing blades are supported by arm members through hollow pivot pins. The hollow pivot pins supporting the leading blade of each blade unit are covered by the trailing blades. Due to the use of hollow pivot pins, the overall weight and driving force of the blade units are effectively reduced to thereby make the shutter free of operational impact without light leakage.

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： In an automatic focusing camera having a shutter control member for controlling the shutter mechanism and a focusing member for regulating the position of the camera lens, an actuating member is provided for controlling the focusing member and the shutter control member. The actuating member is a single slidably mounted element which is movable between a charged position and a rest position and is biased into the rest position. The actuating member actuates the focusing member in the initial stage of movement from the charged position to the rest position and actuates the shutter control member in the final stage of the movement to the rest position.

摘要： An automatic focusing camera capable of automatically focusing the photographic lens thereof by a system actuated by a signal produced by a focus detection circuit when the distance between the object to be photographed by the camera is detected includes an exposure control device comprising an exposure control circuit and an electromagnet. A photographic lens focusing member is movable in response to the shutter release operation and is stopped in response to the magnetizing of the electromagnet. An exposure device is actuated to open to start the exposure after the photographic lens focusing member is stopped, and is closed in response to the demagnetizing of the electromagnet which occurs upon the receipt thereof of the exposure completion signal generated by the exposure control circuit. In this way, a common electromagnet is used for both the focus control and the exposure control to simplify the construction of the camera and to reduce the cost thereof.
