PURPOSE:To obtain a simplified and compact control circuit having the high performance by merging plural record trains into a single train where the records are ascendingly or descendingly rearranged. CONSTITUTION:All records of a subject record train are read out and merged together by a sorting circuit 11. When these records are delivered, the next address having the final record of a record of a termination record 22. This record 22 is read out of a buffer memory 12 in the same way and supplied to the circuit 11. Then the merging process is through when the records 22 of three record trains A-C are held by the circuit 11 respectively. Thus the merging process control is simplified and such circuits that hold the positions of the read records included in a record train, various counter circuits, etc., can be omitted. In such a constitution, a compact control circuit having high performance is obtained. |
