Abstract
PURPOSE: To make it possible to manually render the main circuit of a TV receiver set conductive and inconductive by brining a timer relay into an inconductive condition with the use of a reset switch which is to be turned on and off in response to a main switch.
CONSTITUTION: When a reset switch 61 which is to be turned on and off in response to a main switch 2, a reset circuit 6 detects this to transmit pulsating voltages to a signal line 62. Since these voltages are fed through an OR circuit 7 and a signal line 71 to the reset terminal of an FF 33, this FF 33 reverses its condition to render the timer relay 4 inconductive through a relay drive circuit 41. As a result, even if a timer circuit 3 is in its timer operation, a main circuit 5 can be rendered inconductive by such a manual operation as brings the switch 2 from conductive into inconductive conditions.
