Abstract
PURPOSE: To simplify the selection of the continuous operation of a TV image receiver from the set time and the alarm voice operation by the fixed control of two sets of loads through the RS-type FF or the switching transistor.
CONSTITUTION: When at the time of open state of the resetting switch 47 the alarm signals 48 are added from the terminal 7, through the transistor 8, capacitor 15 or the diode 15 the set input terminal S of the RS-type FF3 keeps a low level even after the extinction of the signal 48 and the output Q reaches a high level to conduct the transistors 23, 25, 17, 18 or 16 for operating the load 33. And, the voice signal of the load 33 operates the load 34 to select the continuous operation of the TV image receiver. On the other part, in the state of "on" of the switch 47 the transistor 23 is not conducted so that the load 33 goes into the state of nonoperation while the transistor 31 is conducted to operate the load 34 through the signals 48 for easily selecting the continuous operation of the TV image receiver from the set time and of the alarm voicing operation.
