Abstract

PURPOSE:To operates a VTR stored in a wooden TV table from the outside without opening the door of the VTR by controlling a 2nd controller with a 2nd remote control signal which is received by a reception part in a 1st equipment to be controlled and sent through a cable and a transmission part. CONSTITUTION:1st and 2nd remote control signals are both infrared rays, so when the VTR 4 is controlled by a 2nd remote control transmitter 5 from the outside, the infrared rays are cut off by the door 3, so that the VTR can not be controlled. A 1st reception part 1a which receives the 1st and 2nd remote control signals is provided in the TV 1, and the cable CA which sends the 2nd remote control signal received by the 1st reception part 1a and the transmission part 6 which is connected to the cable CA and arranged on the internal surface of the TV table 3 are further provided, so that the VTR 4 is controlled without opening the door 3a.

DETAILED DESCRIPTION OF THE INVENTION A) Field of Industrial Application The present invention relates to a remote control device for electronic equipment such as TVs and VTRs.

(B) Conventional technology In recent years, most electronic devices such as TVs and VTRs have been equipped with infrared remote control (hereinafter referred to as remote control) devices as shown in Japanese Patent Publication No. 11538/1983 (H'04B 910o). .

Electronic equipment equipped with the above-mentioned remote control device each has a remote control transmitter, and depending on an independent remote control signal, for example, if a VTR is housed in a wooden TV stand, it is possible to remotely control the TV. However, remote control of the VTR requires opening the door of the TV stand.
There were some inconveniences.

■ Problems to be solved by the invention The present invention has been made in view of the above-mentioned points.
To provide a remote control device which can remotely control even a VTR stored in a stand from outside without opening the door.

B) Problems to be Solved by the Invention The present invention provides a first remote control transmitter that transmits a first remote control signal, a first controlled device controlled by the first remote control signal, and a second remote control signal that transmits a second remote control signal. a second remote control transmitter, a second controlled device controlled by the first remote control signal, and a first controlled device disposed within the first controlled device;
a receiving section that receives, amplifies, and shapes the remote control signal and supplies it to a decoder in the first controlled device, and receives and amplifies the second remote control signal; and a receiving section that receives the second remote control signal amplified by the receiving section; A cable for transmitting data to the outside of the first controlled device, and a transmitter connected to the cable to transmit the second remote control signal, and the second controlled device is controlled by the second remote control signal from the transmitter. be done.

(E) Effect: According to the above-described means, the present invention allows the second controlled device to be controlled by the second remote control signal received by the third receiving section in the first controlled device and transmitted via the cable and the transmitting section. .

(f) Example Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic diagram showing the principle of the present invention, in which (1) is a TV that is a first controlled device, (2) is a first remote control transmitter that controls this TV by a first remote control signal, and (3) ) is a TV stand with a TV (1) placed on it and a wooden door on the front.
(4) A VTR 15j which is housed in this TV stand and is a second controlled device is a second remote control transmitter which controls this VTR by a second remote control signal.

Since both the first and second remote control signals are infrared rays, if you want to control the VTR (4) from the outside using the second remote control transmitter (5), the door (3a)
The door (6a) cannot be controlled because the infrared rays are blocked by
must be opened.

However, in the present invention, the TV+1) includes a first receiving section (1a) that receives the first and second remote control signals,
Furthermore, a cape 71. which transmits the second remote control signal received by the first receiving section (1a). ((to)) and a transmitter (6) connected to the cable knob (CA) and placed on the inner surface of the TV stand (3), for example, the inner surface of the door (3a), and a second remote controller. The second remote control signal from the transmitter (5) is sent from the transmitter (6) and received by the second receiver (4a) in the VTR fJ, so there is no need to open the door (3a) (the VTR (41) It becomes possible to perform control.

Next, FIG. 2 shows a circuit diagram of a main part in an embodiment of the present invention.

In the figure, (7) is the first receiving section (1a) of TV+11.
) is a preamplifier IC for remote control reception that supports the CX20106A made by Sony ■. The ■ pin is the input terminal, and the ■■ pins are the output terminal after amplification and the output terminal after amplification and waveform shaping. be.

(Dl) is a photodiode that receives infrared radiation and converts it into electricity, and is connected to the above-mentioned pin. (Dl) is a diode for half-wave rectification connected to the ■ pin, (Ql) is a drive transistor whose base is connected to this diode, and the collector of this drive transistor and the power supply (Vc
c) is connected to the infrared light emitting diode (D3) in the transmitter (6) to the cape) I (JA).

On the other hand, (8) is the decoder connected to the ■bin and the first
It decodes remote control signals.

Next, the operation of the above-mentioned circuit will be explained with reference to FIG.

First, when operating the first remote control transmitter (2), the first remote control signal is received by the photodiode (D), photoelectrically converted, and input to the ■ pin of the preamplifier IC (71). ) is a signal with a pulse superimposed on a carrier of a predetermined frequency.This first remote control signal is amplified and waveform-shaped within the preamplifier IC, and a signal (E) from which the carrier has been removed is output from the bin. This signal (E) is decoded by a decoder (8) consisting of a microcomputer and controls the TV (11).

Next, when operating the second remote control transmitter (5), the second remote control signal (A) is received by the photodiode (Dl),
It is photoelectrically converted and input to the ■ pin of the preamplifier IC (71). This second remote control signal is amplified by the preamplifier IC (amplified CB in 71), and output from the ■ pin, and is connected to the diode (D
After half-wave rectification (C) in step 2), the drive transistor (Q
l) to the infrared light emitting diode (
D3) is driven by a signal like (D).

Furthermore, when operating the first remote control transmitter (2),
A remote control signal is output to drive the infrared light emitting diode (D3), and when the second remote control transmitter (5) is operated, ■
A second remote control signal is output from the pin, but since the custom codes of both remote control signals are different, no malfunction will occur.

(G) Effects of the Invention As described above, according to the present invention, even if the remote control receiving section of the second controlled device controlled by the second remote control signal is shielded from the outside, the first controlled device By transmitting a second remote control signal to the second controlled device, it is possible to control the second controlled device, and for example, a VTR housed in a wooden 17 unit can be operated from the outside without opening the door.

Further, since the first receiving section in the first controlled device can receive both the first and second remote control signals, the configuration is extremely simple.
