1487982 Remote control of receivers SONY CORP 28 Jan 1975 [29 Jan 1974] 3697/75 Heading H3Q In a remote power control apparatus having a remote control signal processor which includes a switch 7 controlled by a circuit 6 in response to signals from a remote control signal receiver 3 so as to connect the apparatus to an external power source at 1 a battery 5 is connectible to supply an operating voltage to the remote control signal processor 3, 4, 6, a power supply circuit 10, 11 has an input section connected by the switch 7 to be energized from the external power supply and a rectifier section connected to supply an operating voltage to the signal processor when the switch is on and an electronic apparatus 15 is connected to be energized from the external power supply through the switch 7 when the switch is on. When a remote control signal is received by a receiver 3, a control signal generating circuit 4 produces a pulse to switch over the state of a bi-stable circuit 6 which energizes a relay 9 so as to connect power supply switch 7 to turn on the electronic apparatus 15. The A.C. supply from 1 is also supplied via rectifier 11 to recharge the battery 5. The next remote control signal received at 3 causes the bi-stable circuit 6 to switch to the other state to de-energize the relay 9 and disconnect the power supply switch 7. The introduction of the Specification gives a television receiver as an example of the electronic apparatus. |
