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： In a winding up device of a camera settable to an operative position at a phase of exposure completion and to an inoperative position at a phase of winding up completion, there is provided an electromagnetic clutch in transmitting means for transmitting driving force from a drive source of the winding up device. Electrical supply of power to the drive source or winding up motor and the electromagnetic clutch are controlled through a detecting means for detecting the phase of winding up completion to effect rapid changeover between the connection and separation of the driving force of the winding up motor to and from a winding member of the camera, thereby a continuous winding up operation is performed with ease. Power is cut off to the winding up motor switching device and to an electromagnetic clutch switching means to make the film winding up mechanism powerless before a device for stopping the wind up action begins to work.

摘要： A focal plane shutter for a camera includes a shutter unit casing for supporting a shutter mechanism. A rotatable body is connected with the shutter for winding up the shutter to a charged position. A shutter driving spring is also connected with the shutter mechanism for driving the shutter and a holding member is coupled with the rotatable body for holding the shutter mechanism in a charged position. A driving shaft carrying a driving gear is coupled to the rotatable body through a transmission gear and a clutch. A spring is coupled with the clutch to urge the clutch in a direction for releasing engagement between the transmission gear and the rotatable body. The driving gear has a plane section on its circumferential periphery spacing adjacent teeth apart so that engagement between the driving gear and the transmission gear is released when the rotatable body is held so that the transmission gear and the clutch can rotate, under the influence of the spring, back to the initial position.

摘要： The present invention relates to an exposure control apparatus for a camera which is so designed that the output terminal of the light measuring circuit of the brightness of the object to be photographed having a photo electric transducing means is connected to one input terminal of an operation amplifier. The output of the photographing information setting circuit, having a variable resistance means for setting other photographing informations than the information of the brightness of the object to be photographed, is connected to the other input terminal of the above mentioned operation amplifier. This is done in such a manner that proper exposure conditions can be obtained by means of the output of the exposure control circuit connected to the output of the above mentioned operation amplifier. Each input signal to the operational amplifier is adjusted by a bias signal which is controlled in accordance with ambient temperature conditions.
