Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic equipment system, and more particularly, to an electronic equipment system such as so-called AV (audio/visual).

In particular, a system [Summary of the Invention] The present invention provides an electronic device system comprising a plurality of electronic devices including at least a media playback device and a control device for controlling the plurality of electronic devices. is provided, and when this general-purpose operation key is operated, at least the device in the media playback device in which the medium is installed is switched to the playback state, thereby simplifying operations such as selecting an electronic device.

[Conventional technology]

In recent years, it has become popular to combine a plurality of video devices and audio devices in a system to collectively operate and manage them as a so-called AV (audio visual) system. For example, the amplifier (A
As an example of function switching for a V amplifier, when considering input source selection, it is best to provide the same number of source selection buttons as input sources on the front panel of the amplifier.
Traditionally, it has been done to directly operate the desired source selection button, but recently, in order to simplify the operation, input sources are sequentially switched using the up/down keys, and the input source is switched to the desired input source. There are also an increasing number of cases where the 7 sob/down is stopped at the point where the 7 sob/down is stopped. Furthermore, devices constituting an AV system are operated all at once using a single remote control device.

[Problem to be solved by the invention]

By the way, when switching input sources sequentially using the up/down keys mentioned above, when the number of input sources increases, the waiting time until switching to the desired input source increases, which makes the operation more complicated. There's a problem.

In addition, in the case of a multi-function type remote control device that controls multiple devices at once, there are a large number of operation buttons and keys, and even when trying to perform a simple playback operation, there are many It takes time to search for the playback mode selection key for the desired device from among the keys, and it is difficult for people with no knowledge to know whether or not to operate the keys. It's not appropriate.

The present invention has been made in view of these circumstances,
The purpose of the present invention is to provide an electronic device system that allows the most basic operations to be performed with simple operations in an electronic device system such as an A to r system in which a plurality of AV devices are connected.

[Means to solve the problem]

An electronic device system according to the present invention includes a plurality of electronic devices including at least a media playback device, and a control device for controlling operations of the plurality of electronic devices, wherein the control device includes a general-purpose operation key. The above-mentioned problem is solved by controlling at least one of the medium playback apparatuses in which a medium is installed to be switched to a playback state when the general-purpose operation key is operated.

Here, if there are a plurality of playback devices to which a medium is loaded, it is preferable to switch the device to which the medium has been recently (newest) loaded to the playback state.

[For production]

The basic operating mode of a playback device is the playback mode, and when trying to play back a medium such as an audio disc, the medium is generally first installed in the corresponding playback device, so the installation of the medium is performed in response to key operations. By controlling the playback device that is currently being played to be switched to the playback mode, it is possible to automatically select the playback device that is about to be played back.

〔Example〕

An embodiment of the electronic device system according to the present invention will be described below with reference to FIG.

In the embodiment shown in FIG. 1, a so-called mini-component or system stereo device is assumed, and a control device such as a so-called center amplifier is equipped with a so-called compact disk (CD) playback device (CDP).
l. Playing (or recording and playing) a cassette tape 2
The cassette decks 12, ]3 and tuner 14 of the stand are connected.

On the operation panel surface of the control device 20, there are selection keys 21, 22, 23 and 24 for switching and selecting the connected devices 11, 12, 13 and 14, respectively, and an operate key 29 which is a general-purpose operation key. At least it is provided.

The CD playback device 11, cassette deck 12, ]3, which are media playback devices, detect whether or not a medium such as a CD or cassette tape is loaded, and send this medium detection signal to the control device 20. being done. The control device 2o is
In response to the operation of the operation key 29, which is the general-purpose operation key, the state of loading the medium from each of the devices 11, 12, and 13 is confirmed, and the device in which the medium is loaded is switched to the playback operation mode iM#. If there are two or more devices loaded with a medium, the device to which the medium was loaded most recently is switched to the playback mode. If the medium is not installed in any playback device, tuner 14 is selected and placed into reception mode.

Such an operation will be explained with reference to the flowchart shown in FIG. First, after the system is powered on in step S1, the medium is loaded into a desired playback device (step S2), or directly without loading the medium, - using the general-purpose operation key mentioned above. Operate the operate key 29 (step S3). At this time, the control device 20 controls each of the connected playback devices 11,
Step S4 to determine whether the medium is grown or not in 12.13
), if there is a medium, the process proceeds to step S5, and it is determined whether the number of playback devices in which the medium is installed is one, and if it is one (Yes), the process proceeds to step S6, where the playback device concerned is A device is selected, and the process proceeds to the next step S7 to control switching to the basic operation mode (playback mode) of the playback device. If it is determined in step S5 that there are two or more devices (No), the process proceeds to step S8 to select the playback device that has the most recently installed medium, and then in the next step S7 to control switching to the basic operation mode (playback mode). do. If no medium is installed in any of the playback devices in step S4, the process proceeds to step S9 to select the tuner 14, and proceeds to the next step S7 to select the basic operating mode of the tuner 14 (
(reception mode).

In the above explanation, the power-on operation may be omitted; for example, the operation key 29, which is the general-purpose operation key, may be operated from a weak factory-on power supply state such as a so-called standby state. The main power may be turned on to enter the operating state.

According to the electronic device system as described above, a plurality of devices 11- One of the 14 devices that the user is trying to select is selected, and the device is switched to the most basic operating state. For example, if you want to listen to a so-called compact disc (CD), you install a CD player (CDP) 111:CD, and if you want to listen to a cassette tape, you install the cassette tape in the cassette deck 12 or 13. Therefore, as mentioned above, there is a very high probability that the user will select the desired playback device by first selecting the playback device in which the medium is attached. Furthermore, the most frequently used mote of the playback device is the playback mode, which is the basic operating mode, and when the user operates the playback device by simple operation without being aware of the type of operation mode. The reproduction mode is selected with approximately 100% probability. Taking these things into consideration, it is clear that the control state of the device, which is switched and controlled in response to the operation of the general-purpose operation key 29, meets the user's wishes with an extremely high probability. Additionally, it makes sense that the tuner is automatically selected when no media is installed in the playback device, given the typical usage of audio equipment.
The probability that this also meets the user's request is extremely high.

Therefore, even if the audio system is a complex system consisting of multiple connected devices and has more than 100 switchable functions, it can be easily operated to meet the basic needs of the user. It is possible to obtain a normal operating state and improve operability.

Note that the present invention is not limited to the above-mentioned embodiments, and can be applied to, for example, an AV system using so-called AV (audio visual) equipment as the electronic equipment. Further, instead of using a control device that is connected to each device, a remote control device (remote controller) or the like that remotely controls each device may be used. Further, by first selecting an operation mode and then operating a general-purpose operation key such as the above-mentioned operate key 29, an operation such as selecting a device loaded with a medium and controlling switching to the selected operation mode can be performed. Good too. Specifically, for example, if a general-purpose operation key is operated after selecting a recording mode, the device in which the medium is loaded is controlled to switch to the recording operation mode. Furthermore, by first selecting a device and operating a general-purpose operation key, the selected device may have a function that allows basic operations to be performed. It goes without saying that various other changes can be made without departing from the gist of the invention.

〔Effect of the invention〕

As is clear from the above explanation, according to the electronic device system according to the present invention, a general-purpose operation key is provided in a control device that controls a plurality of electronic devices, and when the general-purpose operation key is operated, at least the media playback device Since the device in which the media is installed is switched to the playback state, operations such as selecting an electronic device can be simplified, and operability can be greatly improved.
