ABSTRACT:
A programmed recording device for a VCR without a tuner and a method thereof are disclosed. In the programmed recording device, a microprocessor outputs a control signal when carrying out a recording or a playing, and voltage converting means converts the contorl signal of the microprocessor to a voltage. A voltage detection section detects the voltage after receipt of the output of the voltage converting section, and power source switching means are operated by the power source and in according with the voltage detected by the voltage detecting means. A constant voltage circuit converts the AC power source to a constant DC voltage in a state interlocked with the power source switching section in order to activate the TV. According to the present invention, a recording can be started and terminated at the preset time automatically even without a tuner thereby improving the performance of the products.
