摘要： An interchangeable lens barrel includes connection terminals on a part of the lens barrel for sending and receiving electrical signals to and from a photographic apparatus. The lens barrel part is provided with a mechanism for protecting the connection terminals by covering the terminals when the lens barrel is removed from the photographic apparatus. When the lens barrel is mounted on the photographic apparatus, the protecting mechanism is retracted from the terminals to allow for connection with corresponding terminals on the photographic apparatus.

摘要： In the slit shutter disclosed, an actuator transmits the rotational force of an electromagnetic drive arrangement to move shutter blades through opening and closing cycles. A spring arrangement for engaging the actuating means serves to aid the shutter movement at the beginning of the cycle and retard the shutter movement at the end of each cycle while the spring arrangement is energized during its retarding action. According to an embodiment of the invention, the spring arrangement encounters an arm of the actuator at the end of each cycle, absorbs the arm movement during the retardation, and uses the energization to aid the movement at the start of the next cycle. The spring arrangement again encounters the arm at the end of the next cycle.

摘要： An image pickup apparatus for use in, for example, a camera, includes an image pickup device, an image pickup operation start switch, a recorder, a detector, an image pickup driver, and a controller. The image pickup device can be a CCD for converting an optical image to an electric signal. The image pickup operation start switch starts an image pickup operation in response to a manual operation. The recorder performs a predetermined signal processing of an electric signal provided by the image pickup device and records the processed electric signal on a recording medium driven with a predetermined speed. The detector detects whether a stable speed state of the recording medium is attained. The image pickup driver drives the image pickup device on the basis of a first reference signal for regular image pickup or a second reference signal corresponding to an operation state of the recorder. The controller causes the image pickup device to be driven by using the first reference signal in response to the operation by the image pickup operation start switch. The controller also causes the image pickup device to be driven by using the second reference signal after it is detected on the basis of an output of the detector that a predetermined stable speed state of the recording medium is attained, when the recorder is operated.

摘要： The disclosed shutter time switching device for a rotary shutter is provided with a stepping motor for controlling the opening angle of the rotary shutter. The device includes a driving mechanism for driving the stepping motor in a two-phase driving mode when switching between relatively high shutter speeds and in a single-phase driving mode when switching between relatively low shutter speeds. Optimum responsivity of the switching operation is thus obtained. The stepping motor is rotatable in a first direction and a second direction which is reverse to the first direction. To solve the problem of hysteresis of the motor, the device is provided with a further drive mechanism for driving the stepping motor in the first direction at least one step before a desired step position, regardless of whether the motor has been driven in the first or second direction for switching the shutter speed.
