Abstract
PURPOSE: To simply detect failure of information of the data block at the next stage, by arranging a plurality of data blocks through timing clock being inserted and recording the interval data between data blocks.
CONSTITUTION: A plurality of data blocks DB1, DB2 are arranged on the card 2 via timing blocks TB1WTB3, and the interval data KD representing the information relating to the memory capacity of the timing block TB2 is recorded between the data blocks DB1 and DB2. Further, read-in is made with the shart and end detection circuits 14, 15, interval data read-in circuit 16 and read-in unit including the random access memory 17 and the flip-flop 26. Accordingly, by using the interval data KD, if the information of the data block at the next stage is normal can very simply be detected.
