ABSTRACT:
A data producing device in a signal reproducing apparatus, comprises a shift register supplied with synchronizing signals and codes which are time-sequentially reproduced from a recording medium, synchronizing signal detectors supplied with the synchronizing signals from the shift register, data transfer circuits provided in parallel with respect to each other and in series with the synchronizing signal detectors, and a control circuit for controlling the data transfer circuits so that a data is selectively read out and produced from a desired data transfer circuit among the plurality of data transfer circuits. The reproduced synchronizing signals and codes are transferred to the shift register and are read out from the shift register in response to a clock pulse having a predetermined frequency. The number of the synchronizing signal detectors is equal to the number of kinds of the synchronizing signals, and the synchronizing signal detectors are provided in parallel with respect to each other. Each of the synchronizing signal detectors detect a specific synchronizing signal. A data in a predetermined code among the codes supplied to the data transfer circuits is transferred to the data transfer circuits, when a synchronizing signal for discriminating the predetermined code is detected in the synchronizing signal detectors and supplied to the data transfer circuits.
