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 electromagnetically driven shutter for use in a photographic camera has blades driven by an electromagnetic drive source to move in vertical directions. The electrical power supply control means for the electromagnetic drive source is provided with means for detecting the photographic posture of the camera, whereby the output torque of the electromagnetic drive source is changed as the camera posture changes. This is done in order to insure that the speed of movement of the shutter blades is maintained constant regardless of whether or not the camera is positioned normally, or upside down.

摘要： A shutter device for a still video camera comprises first and second shutter blades, a latch member and an unlatch member. The latch member latches the first blade at its moved position where an image pickup element is exposed to an image light. The first blade is kept latched for a preparatory exposure to correct a set exposure value on the basis of the output of the pickup element or for picking up a motion picture. The unlatch member releases the latching of the first blade. In one embodiment, the unlatch member is provided on the second blade to unlatch the first blade when the second blade is moved to terminate the exposure. In other embodiments, the unlatch member includes an electromagnet to unlatch the first blade.A still video camera comprises a view finder mirror and a mirror operating mechanism. The mechanism includes a motor and is arranged to retract and return the mirror relative to an optical path by utilizing a normal and a reverse rotation of the motor, respectively.In the disclosed embodiments, the camera further comprises a mechanism to maintain the mirror in the retracted condition and a shutter in the opened condition to operate in a motion video mode where an image pickup element is continuously exposed to an image light. The mechanism for setting in the motion video mode may be operable manually from the exterior of the camera or by connecting an external device to the camera.
