A recording apparatus of a helical scan system, including a first video head which records video signals on a magnetic tape when a running speed of the magnetic tape is a standard speed and a second video head which records video signals on the magnetic tape when the running speed of the magnetic tape is approximately 1/N of the standard speed, N being an integer larger than 3.

The reproducing apparatus of the invention reproduces a plurality of band signals which have been subjected to a band division and includes a time-scale modifier which receives the plurality of band signals and time-axis compresses the respective band signals at the same ratio, thereby outputting a plurality of time-axis compressed band signals and a synthesis filter bank for synthesizing the plurality of time-axis compressed band signals.

For a plurality of digital video signals whose frame frequencies are different, a pixel number converting circuit to convert the number of pixels is provided so that differences of the frame frequencies are replaced to differences of the numbers of pixels and a plurality of digital video signals whose frame frequencies are different can be processed by a common clock frequency. The frame frequency is detected by a frame frequency value decoder and the number of pixels in the horizontal direction...

A reproducing apparatus for reproducing signals from a record bearing medium, on which a video signal and some other signal are recorded in a plurality of blocks, includes discriminating circuitry for determining at least whether the signal recorded in each of the blocks is a video signal or other signal, a storing device for storing the result of the discrimination made by the discriminating circuitry, a reproducing unit for selectively reproducing the records of the blocks on the basis of info...

Apparatus are disclosed for reproducing information from an information carrying tape wherein the tape is advanced by the imposition of a first force longitudinally of the tape, and wherein a second force extending into the plane of the tape at an angle to the first force is imposed. A flutter component is detected in information reproduced from the tape, and the second force is varied in response to the detected flutter component in the sense of a flutter reduction. Advantageously, the mentione...

Multimode reproducing apparatus with a first copy catch tray and a bin sorter for collecting and sorting letter and legal size copies and also a generally vertically inclined external copy catch tray adjacent the sorter for collecting oversize copies of oversize originals. The external copy catch tray may also be used to collect any other special copy produced such as copies of magnification reduced from the original.

Phase signals are sensed from the frame synchronizing signals resulting from a PCM magnetic multitrack record tape and applied to a selector connected to a phase locked oscillator. The oscillator is connected to a gate signal generator. The selector responds to each gate signal from the gate generator to pass only one of the phase signals through the same. The oscillator has its phase synchronized with that of the phase signal passed through the selector and provides the phase signals serving to...

A mode change-over mechanism for a tape recording and/or reproducing apparatus wherein the operating mode is selected by depressing a selected one of a plurality of push-buttons. The mechanism includes a pair of operating gears and a pair of independently movable operating members. The operating gears are associated with selected ones of plural push-buttons through respective trigger members. Movement of the first operating member in response to depression of a push-button establishes one operat...

A sampling clock reproducing device wherein binary coded signals representative of letters or other patterns which are superimposed on the television signal and the pilot signal superimposed before the binary coded signals in order to indicate the phase thereof are received, and the phase of the pilot signal is detected whereby clock pulses for sampling the binary coded signals are reproduced.

A tone arm for sound reproducing apparatus comprises an elongated member of electrical insulating material arranged to support a pick-up head at one end and to be pivotally supported at a point remote from said one end. Several spaced electrical current conductors are carried by the elongated member. The electrical current conductors are formed by a printed circuit technique. At least selected conductors are arranged to be connected at one end to a pick-up head mounted on the arm and at the othe...
