Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote control device such as a television receiver, and particularly provides a device having a function of turning off all power supplies.

Conventionally, remote control devices for television receivers have used ultrasonic waves or infrared rays, and their control functions include, for example, channel switching, volume control, and power on/off functions.

However, this type of device does not have an operation function for the preheat power supply that is normally provided in a set power supply, and cannot turn off all power supplies. It felt like a hassle to operate the switch. The present invention is an improvement on this, and the present invention will be explained with reference to an embodiment shown in the figure below. On the set power supply side, a relay RS connected to the switch circuit 51,
, a relay RS2 connected to the switch circuit 52 is installed on the preheat power supply side, and a non-lock switch SW is installed in parallel to the relay RS2, and one input side of the switch circuit 51 is connected to the preheat power supply +B. Connect the consecutive non-lock switches SW2. On the other hand, a receiver RV for receiving a signal from a transmitter TM of a remote control device is provided with a separation circuit RVI connected to the output side of the receiver RV, and one output side of the separation circuit is connected to the other input side of the switch circuit 51. The other output side of the separation circuit RV3 is connected to the switch circuit 52. The separation circuit RVI can be configured as a circuit that has the pulse width of a signal converted into a pulse from a received signal, for example, and separates it into the output end Ti when the width is short and into the output end T2 when it is long, and the switch circuit 51,
52 can be configured as a switch circuit that receives output pulses from these output terminals Ti and T2 and operates using these as trigger pulses. For example, the switch circuit S1 is composed of transistors Tr2, Tr3, etc. as shown in FIG. It is composed of a flip-flop circuit, a transistor Trl connected to its input side, a differential circuit, etc. The operation of the above configuration will be described. To turn the circuit from an all-off state to an on state, first press the switch SWl on the preheat power supply side to bring the circuit into the preheat down state.

As the voltage of the preheat power supply rises, the switch circuit S2 is activated and the relay RS2 is energized, and similarly, the transistor Tr2 of the switch circuit S1 becomes conductive, the relay RS1 is energized, and the set power supply is turned on.

In this case, switching transistors Tr,. are provided, but instead, the switch circuit S1 can be operated by operating a switch SW2, and the power can be turned on and off on the set side. On the other hand, when turning on and off by remote control, if the transmitter TM is operated and the switch is pressed for a short period of time, a pulse is output to the output terminal T1 side of the separation circuit RVl of the receiving shore R, and the switch is turned on. The operation of the flip-flop circuit consisting of the transistors Tr2Tr3 is reversed through the transistor Trl of the circuit S1 and the differential circuit, the transistor Tr3 side becomes conductive, the relay RS1 is deenergized, and the set power supply is turned off.
In this way, if the switch of the transmitter TM is operated for a short period of time, a trigger pulse is given to the switch circuit S1 side, and the relay R
It is possible to control on/off of Sl. Next, when all off is to be performed, the output terminal T of the separation circuit RVl of the receiver RV is pressed by pressing the switch of the transmitter TM for a long time.
An output pulse is obtained on the second side, and the switch circuit S2 is actuated to deenergize the relay RS2 and turn off the preheat power source. As a result, the power of the remote control connected thereto is also turned off, and the relay SS1 is deenergized together with the switch circuit S1, realizing an all-off state. As explained above, in addition to turning on and off the set power supply by remote control, it is also possible to turn off all the power supplies as necessary by a simple switch operation, that is, by a single switch operation.

Note that the above single switch operation uses long and short pulses to separate signals, but other means of separating signals include, for example, using a single switch operation to separate signals with different frequencies or code signals instead of using pulse widths. how to oscillate,
Furthermore, it is possible to transmit two types of signals by dividing the pressing force of the switch into stronger and weaker ones.
