Abstract: A wireless output unit of a remote controller 2 having a touch pad 23 or a touch panel wirelessly outputs a coordinate value associated with a continuous contact input for the touch pad 23 to a television 1. A reception unit of the television 1 wirelessly receives the coordinate value associated with the continuous contact input output from the wireless output unit. A display processing unit displays on a display unit 14 a pointer 3 moving on the basis of the coordinate value received by the reception unit. An output unit outputs, when the continuous contact input is finished, acceptance information indicating that an input for an object T displayed on the display unit 14 is accepted at a final coordinate value for the pointer 3 displayed on the display unit 14.

Abstract: A wireless output unit of a remote controller having a touch pad or a touch panel wirelessly outputs a coordinate value associated with a continuous contact input for the touch pad to a television. A reception unit of the television wirelessly receives the coordinate value associated with the continuous contact input. A display processing unit displays on a display unit a pointer moving on the basis of the coordinate value received by the reception unit. A reducing unit reduces the moving rate of the pointer 3 on the basis of the coordinate value received by the reception unit, when the distance between an object T displayed on the display unit and the pointer 3 displayed on the display unit is within a predetermined distance. An output unit outputs, when the continuous contact input is finished, acceptance information indicating that an input for an object T displayed on the display unit is accepted at a final coordinate value for the pointer 3 displayed on the display unit.

Abstract: An optical information reproducing apparatus for reproducing an information recorded on a recording surface of a disc shape record medium is disclosed, which includes an optical pick-up device mounted on a tiltable optical block and having a laser beam source for generating a laser beam and a photo detector for detecting the refelected beam from the recording surface and for reproducing the recorded information, a device for rotating the record medium, a skew error detector for detecting a skew of the record medium relative to the optical pick-up device and for generating a skew error signal having a D.C. component and an A.C. component, a control circuit supplied with the skew error signal and for generating a control signal responsive to the D.C. component of the skew error signal, a skew error corrector controlled by the control signal and for controlling the optical block so that the optical axis of the pick-up device is maintained to be always perpendicular to the recording surface.

Abstract: A video signal recording and reproducing apparatus used with a disc as recording medium comprises a head assembly, a disc rotating drive for rotating the disc in relation to the head assembly, a signal path extending from an input terminal to which a video signal is supplied to be recorded to the head assembly, a first control circuit for controlling the disc rotating drive so as to vary the disc rotation in response to the phase of a synchronous signal, such as a horizontal synchronous signal in the video signal supplied to the input terminal, a variable delay provided in the signal path for delaying the video signal supplied to the input terminal to vary the time base thereof, and a second control circuit for controlling the delay time in the variable delay so as to vary the time base of the video signal derived from the variable delay in response to the phase of a reference signal, such as a horizontal reference signal reproduced from the disc through the head assembly.

Abstract: An optical reproducing device for reproducing information from a rotating record medium includes a focus control system for displacing a focusing lens perpendicular to the plane of the record medium. A light beam is conducted through the focusing lens on to the record medium. A capture range search system is provided to move the focusing lens at a substantially constant speed from a rest position until it is positioned within the capture range of the focusing control system. The capture range search system includes a bridge circuit for sensing the moving speed of the focusing lens. The bridge circuit includes a moving coil of a drive motor for said focusing lens and a variable impedance element. The bridge circuit is balanced by controlling the variable impedance element when the lens is at the rest position.
