Title: Video signal reproducer
Inventor: NISHIMURA AKIMASA
IPC: G11B20/02
Filed: 1983-06-22
Abstract: PURPOSE:To prevent a reproduced picture from deteriorating by automatically switching to the reproducing condition of the field mode by another reproducing head, when the output of one reproducing head of the two is lower than a reference level. CONSTITUTION:When the outputs from detecting circuits 14 and 15 are supplied to comparators 16 and 17 and the outputs of the detecting circuits 14 and 15 are higher than a reference level, the outputs of the comparators 16 and 17 become a low level and it is displayed that the reproducing output condition of both heads is normal. Since the output of the comparator 17 becomes a high level and an R-SFF 20 also becomes a high level when the output of one of the two reproducing heads H2 does not reach a reference level, the outputs of OR circuits 22 and 26 become a high level and the abnormal condition is displayed on a display device 24 and, at the same time, an opening-closing switch 9 is opened and change-over switch 10 is switched to a terminal 10b. Therefore, the output of the reproducing head H2 is interrupted and only the output of the other reproducing head H1 is supplied to a signal processing circuit 11 through switches 12 and 10.
