    摘要： A focusing apparatus for video camera or the like in which a change-over between automatic focusing and manual focusing is possible comprises an endlessly rotatable and hand-worked manipulator, a detector for detecting the direction and amount of manipulation or rotational movement of the manipulator, and a controller/driver for moving a part of optical elements in an optical system along its optical axis direction in a direction corresponding to the direction of manipulation of the manipulator detected by the detector and by a distance corresponding to the amount of manipulation of the manipulator detected by the detector, thereby taking the focus.

    摘要： A portable IC card reader for retrieving information from an IC card incorporating a semiconductor memory device and for displaying at least part of retrieved information. The portable IC card reader, which is of a size suitable to fit in a clothes pocket, a bag, or the like, includes a housing having a display portion provided on a part of the housing for displaying at least part of the retrieved information, and incorporating a controller. The housing further includes, at least at a part of the surface thereof, an IC card insert port through which the IC card is inserted and an IC card accommodating unit extending straight from the IC card insert port to an opposite side of the housing. The housing further includes a foreign-matter ejection exit formed by extending the IC card accommodating unit and opening at the opposite side of the integrated-circuit card insert port. In operation, foreign matter is ejected form the IC card accommodating unit by insertion of the IC card, thereby advantageously preventing the IC card reader from malfunctioning as a result of the foreign matter.

    摘要： A video camera has a memory for storing the position of an image lens in relation to the position of a variator lens, that is, zoom tracing curves in respect of individual subject distances, a motor for moving the image lens while vibrating it slightly during zooming operation, a variation component extractor circuit for extracting the amplitude and phase of a slight variation component of focusing voltage generated by moving the image lens while vibrating it slightly, and a controller for controlling drive means on the basis of the stored zoom tracing curves and an extracted slight variation component. During zooming operation, the controller first controls the motor in compliance with a position of the variator lens pursuant to a zoom tracing curve stored in the memory in association with a position assumed by the image lens immediately before start of the zooming operation. The controller also operates to correct a drive amount of the image lens on the basis of amplitude of an extracted slight variation component and when the amplitude of the slight variation component falls below a predetermined value, the controller controls the motor pursuant to a newly determined zoom tracing curve.

    摘要： An electronically-controlled focusing adjustment apparatus including manual focusing adjustment means using a manual focusing adjsutment device such as a variable resistor, focusing lens position detection means, and feedback means for comparing a voltage outputted from a movable terminal of the manual focusing adjustment device with a voltage outputted from the focusing lens position detection means and for feeding back the error between the two voltages to a motor for driving the focusing lens. Desired manual focusing is thus attained with respect to an object located at an arbitrary distance.

    摘要： An automatic focusing apparatus for a video camera converts the quantity of reflected light reflected by an object into an electric signals by light receiving elements. The electric signals are detected and the detected signals are integrated by integrators once every fixed period. A decision is made on the basis of the respective outputs of the integrators whether or not the video camea is in focus. The detectors and the integrators have offset voltages, respectively. The outputs of the integrators are sampled and held and are compared with a reference voltage equal to a voltage for resetting the integrators. Signals representing the result of the comparison are fed back to the detectors or to the integrators to regulate the offset voltages of the detectors and the integrators.

    摘要： An automatic focusing apparatus comprises a light emitting element emitting a beam of electromagnetic radiation directed toward a subject through a light projecting lens, a light receiving element receiving a beam spot reflected from the subject and passing through a light receiving lens, and a parallel-surface transparent plate disposed rotatably between the light receiving lens and the light receiving element. The parallel-surface transparent plate is rotated in interlocking relation with linear movement of an optical lens moving together with movement of a focus ring, thereby automatically attaining the focus by ceasing the movement of the lens optical system as soon as the output signal of the light receiving element attains a predetermined level.
