发明名称 TIME CORRECTION SYSTEM FOR REPRODUCING SIGNAL IN PIANO AUTOMATIC PLAYING UNIT
摘要 PURPOSE:To correct the shift of time of reproduced automatic playing through the correction of time difference between bits, by operating the serial data every one frame including the reproduced playing information and the synchronizing signal at the same time point for the entire bits. CONSTITUTION:The reproducing signal from the tape recorder 1 is fed to the synhronizing pulse detection circuit 5 via the decoding circuit 3 and the reference clock generating circuit 4 and data are serially given to the shift register latches 9-14 and 16-22 in series connection evey one frame, the data are all stored and the write-in signal based on the synchronizing signal is produced. Further, the playing information stored in all the shift register latches is parallelly output at a bundle and all the information is processed in the same timting. Accordingly, the serial data is operated to all the bits at the same time point, the shift in the time of reproducing playing is avoided, allowing the reproduction with fidelity.
