Abstract: A system having a system control section and a tape driving mechanism section, in the case where a tape in which subcode data representing the beginning position of a tune is recorded is reproduced, takes out the subcode data from reproduced signals, judges whether the beginning portion of the tune is being reproduced or not, and if is not, makes a tape driving mechanism carry out a search operation so that the tune is reproduced from its beginning.

Abstract: An automatic flaw detection apparatus comprises a supporting frame; a hollow shaft which is supported on said frame in a freely rotatable manner through a bearing, and through the interior of which passes a material to be inspected; a holder disposed within said hollow shaft, and extending in the longitudinal direction of the axis of said hollow shaft, and rotating in association with said hollow shaft; sensing means incorporated in said holder to detect any defect in said material to be probed; and a signal transmission device interposed between said hollow shaft and said supporting frame, and to transmit the flaw detection signal from said sensor means to outside.
