As shown in the figure, numerals 1 and 3 indicate remote control sections, and numerals 2 and 4 indicate audio equipment operated by the remote control sections 1 and 3, respectively.

Each remote control unit 1, 3 includes an operation switch 5 corresponding to an operation switch 10 (described later) in each audio device 2, 4, a coding circuit 6 that encodes the input thereof, and sends out a coded signal. A transmitting element 7 is provided.

On the other hand, each audio device 2, 4 includes a receiving section 8 that receives the coded signal from the transmitting element 7, a decoder 9 that decodes the received signal, and an on/off switch 10 that turns on the operating switch 10 based on the decoded signal. A control circuit section 11 is provided that outputs an operation command signal for operating its own functions including /off and instructing other audio equipment 2 or 4 to perform related operations in response to this operation. Also,
Each audio device 2, 4 includes an audio signal circuit section 12 of each audio device, an audio signal terminal 13, and the other audio device 2 or 4.
An operation command signal terminal 14 for transmitting an operation command signal from the control circuit section 11 is provided. Each audio device 2, 4 has an audio signal line 15 connecting each audio signal terminal 13 and each operation command signal terminal 1.

Similar operations are performed between the remote control section 3 and the audio equipment 4 as well.

(Problem to be solved by the invention) As described above, in the conventional audio equipment described above, each audio equipment is provided with a remote control unit and a receiving unit for receiving signals to be remotely controlled. Each audio device is connected via a predetermined signal line.

Therefore, when these audio devices are systemized, the number of remote control units and reception units increases depending on the number of each audio device, which not only complicates the signal line but also makes it difficult to operate the desired audio device. In such cases, it is necessary to operate a remote control unit corresponding to each audio device.

As a result, there are problems in that the cost for systematization increases and the operation becomes complicated.

The present invention has been developed in response to these circumstances, and aims to provide a remote control device that can reduce costs and improve operability when systematizing audio equipment.

(Means for Solving the Problem) In order to achieve the above object, the present invention provides a remote control device that decodes a coded signal consisting of a plurality of pulse trains by remote control from a remote control unit, and decodes a coded signal consisting of a plurality of pulse trains based on the decoded signal. to operate its own functions,
In response to this operation, the operation of each predetermined function of the audio system is controlled by instructing other audio equipment to perform related operations using an operation command signal consisting of a pulse whose width is wider than the on-width of each of the above-mentioned pulses. In the remote control device that instructs, any one of the audio devices in the audio system combines the operation command signal and the coded signal with a common receiving section that receives the coded signal, and simultaneously transmits the command signal to the other audio system. and a composite signal output section for outputting to an audio device.

(Function) In the remote control device of the present invention, a coded signal by remote control is received by a common receiving section common to each audio device, and furthermore, the coded signal is received by a common receiving section common to each audio device, and the coded signal is added to the operation command signal output from the side provided with the common receiving section. Since the coded signals are combined and sent to other audio equipment, only one remote control section and one receiving section are required when building a system.

It also consists of multiple pulse trains that indicate remote control instructions from the remote control unit and pulses that have a width wider than the ON width of each pulse for instructing other audio equipment to perform related operations according to the operation of its own function. Since the operation command signal and the operation command signal are combined and sent out at the same time, it is possible to quickly shift each audio device to a predetermined operation based on an instruction from the remote control section.

(Example) Hereinafter, details of an example of the present invention will be described based on the drawings. Note that parts common to those in FIG. 5 are given the same reference numerals, and redundant explanations will be omitted.

As shown in the figure, reference numeral 1 indicates a remote control unit, and reference numerals 2 and 4 indicate audio equipment operated by the remote control unit 1. As shown in FIG.

The remote control section 1 is provided with an operation switch 5a, a coding circuit 6, and a transmitting element 7.
However, the number of operation switches 5a of the remote control section 1 is greater than that of the conventional example in order to operate a plurality of audio devices individually.

On the other hand, each of the audio devices 2 and 4 includes decoders 9a and 9b, a control circuit section 11a that outputs an operation command signal, an audio signal circuit section 12, audio signal terminals 13a and 13b, and a control circuit section 11a that outputs an operation command signal and a coded signal. Terminals 14a and 14b for operation command signals are provided for simultaneously inputting and outputting synthesis signals. The audio devices 2 and 4 are connected via an audio signal line 15 connecting the audio signal terminals 13a and 13b and an operation signal line 16 connecting the operation command signal terminals 14a and 14b. However, in this example, a common receiving section 8a common to each audio device is provided on the audio device 2 side. Further, the coded signal from the common receiving section 8a in the audio device 2 is combined with the operation command signal of the control circuit section 11a, and simultaneously sent to the other audio device 4 via the signal line 16. Further, on the other audio equipment 4 side, the combined input signal from the terminal 14b is input to the decoding circuit 9b and the control circuit section 11b.

In the remote control device having such a configuration, when the operation switch 5a of the remote control section 1 is operated, the coding circuit 6 encodes the input. The encoded signal is then transmitted to the audio equipment 2 by the transmitting element 7. Here, as shown in FIG. 2, for example, the coded signal consists of a plurality of pulse trains, and the ON width of each pulse is extremely narrow.

On the audio equipment 2 side, when the common receiving section 8a receives the coded signal, the decoding circuit 9a decodes the signal and sends it to the control circuit section 11a.

The control circuit unit 11a operates its own functions, including turning on/off the operation switch 10, based on the decoded signal, and issues operation commands for instructing other audio equipment 4 to perform related operations in response to this operation. Output a signal. The operation command signal from the control circuit section 11a is sent to each operation command signal terminal 14.
The signal is sent to other audio equipment 4 via the operation signal line 16 connecting the signals a and 14b.

At this time, the operation command signal output from the control circuit section 11d has a pulse on-width that is sufficiently wider than the on-width of each pulse shown in FIG. 2, as shown in FIG. 3, for example. . Further, the signal sent from the operation command signal terminal 14a is a combination of the pulses shown in FIGS. 2 and 3, as shown in FIG. 4, for example.

On the side of the audio equipment 4 that has received the composite signal, the control circuit section 11b receives only the operation command signal shown in FIG. 3, and the decoding circuit 9b receives only the encoded signal shown in FIG.

Next, the decoding circuit 9b decodes the signal and sends it to the control circuit section 11b. The control circuit section 11b operates its own functions including turning on/off the operation switch 10 based on the decoded signal and the operation command signal.

As described above, in this embodiment, a coded signal from a remote control is received by a common receiving section common to each audio device, and the code is further added to the operation command signal output from the side provided with the common receiving section. Since the signals are combined and sent to other audio equipment, only one remote control section and one receiving section are required when building a system.

It also consists of multiple pulse trains that indicate remote control instructions from the remote control unit and pulses that have a width wider than the ON width of each pulse for instructing other audio equipment to perform related operations according to the operation of its own function. Since the operation command signal and the operation command signal are combined and sent out at the same time, it is possible to quickly shift each audio device to a predetermined operation based on an instruction from the remote control section.

(Effects of the invention) As explained above, according to the remote control device of the present invention, when systemizing the remote control unit and the receiving unit, each audio device can perform predetermined operations based on instructions from the remote control unit. Since the transition to the system can be made quickly, it is possible to reduce costs and improve operability when systematizing audio equipment.
