Filed: 1986-02-03
Abstract: PURPOSE:To completely remove a trouble of resetting a self timer even when an irregular rotation of a magnetic disk is generated on the way of an operation by photographing, and recording on the magnetic disk when the rotation is stabilized. CONSTITUTION:At the time t8 when the prescribed number of clock pulses is counted from the time t5, the signal of the output terminal OUT of a counter 42 goes to H, while a lock in detection signal at this time goes to L, so that the output of a NAND gate 50 remains H. If the rotation of the magnetic disk 18 is stabilized again and the lock in detection signal goes to H at the time t9, since the signal of the output terminal OUT of the counter 42 is H, the output of the NAND gate 50 changes from H to L according to this change of the lock in detection signal. An MM52 responds to the fall of the output of the NAND gate 50 at the time t9 and generates a pulse 78 of a prescribed duration. This pulse 78 is impressed to an image pickup signal processing circuit 12 and a recording circuit 14 as a recording start signal and both the circuits start the prescribed operation and the photographing and the recording to the magnetic disk 18 are carried out.
