摘要： In a recording or reproducing apparatus of the kind recording or reproducing information on or from a disc-shaped magnetic sheet which is contained in a cassette, if the magnetic sheet is left over a long period of time in a stationary state in contact with a magnetic head on one side thereof with a stabilizer plate closely opposed thereto on the other side, the magnetic sheet tends to be locally deformed and, if the apparatus is portable, the magnetic head might be damaged by collision with the sheet as the sheet vibrates while the apparatus is carried around. The disclosed apparatus is provided with retracting means for retracting the magnetic sheet and the stabilizer plate away from the magnetic head while leaving the cassette unmoved, so that the possibility of having the magnetic sheet deformed and the magnetic head damaged by the vibration of the sheet while the apparatus is carried around can be eliminated with the magnetic sheet and the stabilizer plate retracted from the head.

摘要： A recording system comprises an image pick-up recording device to record the picture information obtained through the image pick-up on a recording medium by a recording head; and a control device to change the relative location of the head and the medium after the information of one picture has been recorded in a predetermined location on the medium and to prevent the next picture information from being read out during the period of time until the completion of that displacement. The recording sytem may be provided with a memory for the picture information and a control device for allowing part of the picture information to be recorded in the selected portion on the medium. The control device also permits the other portion of the picture information stored in the memory to be recorded in the other portion on the medium after changing the relative location of the head and the medium.

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： A motorized driving device for a camera is arranged to operate selectively in the film winding and rewinding modes. A switching mechanism allows the electric motor to rotate in only one direction. When the camera is switched from the rewinding to the winding mode, the switching mechanism is maintained in a motor current supply position for a certain prolonged period, so as to ensure that a reversed drive torque is transmitted by the device.

摘要： Driving power of an electric motor is transmitted to wind up a photographic film on a spool and to charge the shutter and other mechanisms associated therewith. When the spool has wound up the film by one frame, the transmission of the driving power to the spool is cut off through a clutch mechanism. After the charge member has completed its operation of charging the shutter and the motor is de-energized, the clutch mechanism is rendered effective in response to return of the charge member to the initial position, whereby the transmission of the driving power to the spool is again ready to be performed.
