[Summary of the idea]

The present invention provides an electronic device control device in which, for example, an audio device is controlled by a controller and a timer device is used to perform a timer operation, in which a power supply on/off command signal supply line is connected between the controller and the timer device. By connecting the electronic device and the controller so that it can be transmitted from both the controller and the timer device, the controller can control the electronic device regardless of whether the timer device is operating the timer or not. It is possible.

[Conventional technology]

Conventionally, as a method of connecting audio equipment, it has been proposed to connect each equipment such as an amplifier, a tuner, and a tape deck via a selector, and to select each equipment using the selector. On the other hand, timer devices are commercially available that perform so-called timer operations that cause these audio devices to operate at predetermined times.

FIG. 2 is a diagram showing a connection when a timer device is used in an audio device connected using the above-mentioned selector. In the figure, 1 indicates a timer device, and this timer device 1 starts or stops supplying power obtained from an outlet 2 to an interlocking output terminal 2a at a preset time. The interlocking output terminal 1a of the timer device 1 is connected to the power input terminal of the selector 3 via the power line 4. Further, the power output terminal of the selector 3 is connected in parallel to the power input terminals of the amplifier device 5, the tuner 6, and the tape deck 7 via the power line 4, respectively. Note that connections of audio signal lines are not shown.

By connecting in this way, during normal use, the power obtained from the outlet 2 of the timer device 1 is constantly supplied to the selector 3, and is also supplied to the amplifier device 5, tuner 6, and tape deck 7 via the selector 3. . The selector 3 is activated by this power supply, and, for example, a remote control signal is transmitted from the remote control transmitter 8 to the selector 3, and one of the tuner 6 and the tape deck 7 is selected by this signal. Then, a connection is made by the selector 3 so that the audio signal obtained from the selected device is supplied to the amplifier device 5, and this audio signal is reproduced by, for example, a speaker (not shown) connected to the amplifier device 5. When the timer device 1 performs a timer operation, the above-mentioned selection is made in advance using the selector 3, and then a start time and an end time are set by the timer device 1, and the timer device 1 is interlocked until the start time is reached. Output terminal 1
Do not output the power obtained from a to outlet 2,
The power obtained from the interlocking output terminal 1a is outputted to the outlet 2 only from the start time to the end time. By doing so, power is supplied to the device selected by the selector only from the start time to the end time, and the device is operated and performs operations such as playback.

[Problem that the invention attempts to solve]

However, in the case of a conventional electronic equipment control device connected as shown in the example in FIG. Even if an attempt was made to transmit a remote control signal from the selector 8 to the selector 3 to perform playback, etc., since the selector 3 was not supplied with power, it would not operate at all and the various devices could not be operated. Therefore, when performing various operations using the selector 3 before the start time and after the end time of the set timer operation, there is an inconvenience that the timer operation set in the timer device 1 must be canceled.

In view of the above, an object of the present invention is to provide an electronic equipment control device that allows electronic equipment to be controlled from a controller such as a selector, regardless of whether or not the timer is operating.

[Means for solving problems]

The electronic device control device of the present invention has electronic devices 5 and 7, a controller 10, and a timer device 9, as shown in FIG. 1, for example, and the controller 10 controls the electronic devices 5 and 7. In an electronic device control device in which a timer device 9 performs timer operations of electronic devices 5 and 7, power on/off command signal supply lines 11 and 12 are bidirectionally transmitted between a controller 10 and a timer device 9. The electronic devices 5, 7 can be connected to each other from both the controller 10 and the timer device 9.
Also, the controller 10 can be turned on and off.

[Effect]

The electronic device control device of the present invention allows the electronic devices 5, 7 and the controller 10 to be controlled from both the controller 10 and the timer device 9, regardless of whether or not the timer device 9 is in operation. , controller 10
It is possible to control the electronic devices 5 and 7 from there.

〔Example〕

Hereinafter, one embodiment of the electronic device control device of the present invention will be described with reference to FIG. This first
In the figure, parts corresponding to those in FIG. 2 are denoted by the same reference numerals, and detailed explanation thereof will be omitted.

The electronic equipment control device shown in FIG. 1 of this example is configured as a control device for audio equipment, similar to the example of FIG. 2. In FIG. 1, 9 is a tuner with a timer function, and this tuner 9 with a timer function has a tuner circuit system and a timer circuit system, and a non-interlocking output terminal 9a that constantly outputs the power obtained from the outlet 2; Interlocking output terminal 9b whose power output is controlled by a timer circuit system
Equipped with. The non-interlocking output terminal 9a is connected to the power input terminal of the selector 10 via the power line 4, and the interlocking output terminal 9b is connected to the power input terminals of the amplifier device 5 and the tape deck 7 via the power line 4. Further, the tuner 9 with a timer function and the selector 10 are connected by two first and second command signal lines 11 and 12, and the first command signal line 1
From tuner 9 with timer function to selector 10
A signal for commanding power on/off of the selector 10 is supplied to the selector 1 through the second command signal line 12.
0 supplies a signal to the timer function tuner 9 to instruct the tuner circuit system of the timer function tuner 9, the amplifier device 5, and the tape deck 7 to turn on and off.

With the above configuration, the selector 10 ensures that the power obtained from the outlet 2 is connected to the non-interlocking output terminal 9a of the tuner with timer function 9, regardless of whether or not the start time and end time have been set by the timer function. When the timer function is not set at all, and before and after the set start time and end time, the selector 10 is always ready to receive command signals from the remote control transmitter 13. In this standby state, the signal receiving circuit from the transmitter 13 of the selector 10,
Only for the timer circuit system of tuner 9 with timer function.
Power is on. In this standby state, when a command signal is transmitted from the remote control transmitter 13 to the selector 10, for example, to reproduce the FM broadcast received by the tuner 9 with a timer function from a speaker (not shown) connected to the amplifier device 5, The power to each operating section of the selector 10 is turned on, and connections are made so that the audio signal from the tuner with timer function 9 is supplied to the amplifier device 5. Then, a signal is supplied to the tuner 9 via the second command signal line 12 to instruct to turn on the power of the tuner circuit system of the tuner 9 and the amplifier device 5, and the power of the tuner circuit system of the tuner with a timer function 9 is turned on. At the same time,
Power is supplied to the amplifier device 5 from the interlocking output terminal 9b, and the power of the amplifier device 5 is turned on. By turning on the power of each device in this way, the FM broadcast is played back. When stopping playback, the device returns to the initial standby state. That is, the tuner circuit system of the tuner 9 and the amplifier device 5 are turned off by a signal via the second command signal line 12, and
Turn off the power to each operating section of the selector 10.

When setting the start time, end time, etc. using the timer function of the tuner 9, for example, you can set the tape deck 7 to record the FM broadcast played by the tuner 9 with the timer function at a predetermined time. Then, when the start time arrives, the tuner with timer function 9 supplies a signal to the selector 10 via the first command signal line 11 to instruct to turn on the power of each operating section of the selector 10, and turns on each operating section of the selector 10. The power is turned on and connections are made so that the audio signal from the tuner with timer function 9 is supplied to the tape deck 7. and,
The power to the tuner circuit system of the tuner with timer function 9 is turned on, and at the same time, power is supplied to the tape deck 7 from the interlocking output terminal 9b to turn on the power to the tape deck 7. In this way, the power of each device is turned on, and the FM broadcast is recorded.
When the end time comes, a signal instructing to turn off the power to each operating section of the selector 10 is supplied via the first command signal line 11, and the power to each operating section of the selector 10 is turned off. The tuner circuit system 9 and the tape deck 7 are turned off, and the system returns to the standby state.

As described above, according to the control device according to this example, various operations can be performed on the selector 10 side without canceling the timer operation even when the timer operation is set and the timer is waiting until the start time or after the end time. . Therefore, for example, various operations can be performed from the remote control transmitter 13 at any time, and the operator does not need to directly operate the tuner 9 with a timer function.

In the above embodiment, the timer device is tuner 9.
However, it can be constructed in the same way even if it is separate from the tuner. Furthermore, although the above-mentioned embodiment is a control device for audio equipment, it can be applied to a control device for various electronic devices, such as a control device for video equipment or a control device for equipment that combines both video equipment and audio equipment. Furthermore, it goes without saying that the present invention is not limited to the above-described embodiments, and that various other configurations may be adopted without departing from the gist of the present invention.
