Abstract

PURPOSE: To make absence recording, etc., easy and secure by starting recording operation, etc., controlled by a safety switch setting FF with a signal delayed behind electric power supply after a timer time elapses.
CONSTITUTION: With electric power switch 20 closed after a timer time, capacitor C2 of electric power circuit 17 is charged and the delay output of the delay circuit, etc., of decoder 9 is differentiated by the differentiating circuit of capacitor C1, etc., so that transistor Q1 will conduct a fixed delay time after the electric power supply. Consequently, FF1 set in reproduction or recording operation with the high- level output of NAND gate 2 whose input terminals are both held at a low level is set through timer-set switch 10. When safety switches 18 and 19 are left opened through recording bias circuit 12 and control circuit 11 with this set output, recording following erasing operation is carried out and when closed, reproduction is put into operation, so that absence recording, etc., free from malfunction will be performed through easy operation.
