摘要： Disclosed is a single lens reflex camera having an electrically driven focal plane shutter. A locking arrangement locks the shutter curtains in their start positions before shutter release to prevent unintentional actuation of an exposure due to faulty operation of switches, shock, or the like. Upon completion of the upward movement of the quick return mirror, the locking mechanism is disabled.

摘要： A camera having an electromagnetic driving source for operating a focal plane shutter in the camera, includes a shutter base plate and a driving arm pivoted on the base plate for swinging movement in a plane parallel to the plate. A group of thin shutter blades are supported on the driving arm parallel to the surface of the base plate. The output shaft of a motor is coupled with the driving arm, and either one of the rotor of the motor, or a permanent magnet forming a part of the stator of the motor, provides magnetic flux parallel to the axis of the output shaft, thereby causing the rotor to rotate the output shaft and drive the focal plane shutter.

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.

摘要： An image sensing device comprises image sensing apparatus for converting an optical image into an electrical signal; shutter apparatus for blocking light incident upon the image sensing apparatus; periodic signal generating apparatus for forming periodic signals which are produced for periodically reading the electrical signal of the image sensing apparatus; a switch for giving an instruction to operate the shutter apparatus; first timer apparatus to operate in response to a predetermined periodic signal produced after the switch is operated; and shutter driving apparatus which begins to operate for opening the shutter apparatus after the lapse of a predetermined time counted by the timer apparatus. The device is capable of cancelling a delay in the operation of the shutter apparatus, etc. by the first timer apparatus. The device is provided with closure detecting apparatus to detect a shift of the shutter apparatus from an open state to a closed state; and an inhibiting apparatus to inhibit the above-stated reading by the periodic signal generating apparatus until the output of the closure detecting apparatus is obtained after commencement of a still picture image sensing process. This arrangement deletes any adverse effect of a bounce or bound of the shutter apparatus even if it takes place at the end of a shutter travel. The device is provided further with second timer apparatus which operates in response to a predetermined periodic signal obtained after the switch is operated. The shutter driving apparatus starts to open the shutter apparatus after the lapse of a predetermined length of time counted by the first timer apparatus and starts to close the shutter apparatus after the lapse of another length of time counted by the second timer apparatus, so that the shutter apparatus can be opened and closed with highly precise timing.

摘要： A video recording camera having a movable head and actuating apparatus for controlling an exposing state of an image pick-up apparatus, wherein the internal structural arrangement of the camera is simplified for a head shifting apparatus and for a charging apparatus which accumulates an urging force for the actuating apparatus. This arrangement results in a reduction in size of the video recording camera. This arrangement enables a successive shot function in addition to a single shot function, and causes the head to shift to a position on a recording medium coinciding with a position indicated by an indicating member on the recording medium container while inhibiting power from being supplied to other operating systems of the camera until the coincidence is achieved.
