Description

[Detailed description of the invention] [Field of industrial application] The invention is applicable to video systems configured by connecting video equipment such as video tape recorders, video disc players, and television receivers, or to audio tape recorders and records. In audio systems configured by connecting audio devices such as players, compact disc players, tuners, integrated amplifiers, and speakers, or AV systems configured by connecting video devices and audio devices, each device of these systems is The present invention relates to an operation panel for an operation device that is connected to operate these devices.

[Conventional technology]

Conventionally, for example, as shown in FIG. 7, a video disc player 1 and a video tape recorder 2 are connected to a television receiver 3, and the audio outputs of the compact disc player 4, tuner 5, tape player 6, and television receiver 3 are connected to an integrated amplifier. Connect to 7,
An AV system may be constructed in which the speaker 8 is driven by the output, and each device is operated by the operation section of the integrated amplifier 7.

Further, this integrated amplifier 7 may be operated by a remote control device 9.

In this case, in the operation section of the integrated amplifier 7,
Each device is usually displayed, and operating members such as knobs and switches for operating the device are usually provided in conjunction with the display.

[Problem that the invention attempts to solve]

In an operating device such as the integrated amplifier 7 that operates each device in the system, each device is displayed on the operating member by a print, an electric light, or the like.

However, this display is displayed even if each device that makes up the system is not connected to the operating device.
Because the print or electric display continues to display, the user may have the illusion that the device is connected and operate the operating member.

Moreover, the more devices that can be connected to the operation panel of such an operation device, the more operation members it will have, and this has the disadvantage that it is easy to make mistakes.

[Purpose of invention]

The present invention is intended to eliminate the above-mentioned drawbacks of the operation panel in conventional systems.If there is a device that is not connected to the operation device, the operation panel for that device is not displayed. The purpose is to reduce erroneous operation of operating members for devices that are not connected, and to reduce display on the operating panel.

[Summary of the idea]

In order to achieve the above-mentioned object, the present invention displays the display on the operation panel of the operation device of the system using a display member that performs display when energized.
The gist of the system is that a switch that operates when the device is connected is provided at the terminal for connecting each device, and the switch energizes the display member to display the display.

[Example of idea]

An embodiment of the present invention is based on the case where an AV system as shown in FIG. 7 is operated by the integrated amplifier 7, and the integrated amplifier 7 becomes the operating device.
FIG. 1 and FIG. 2 will be explained.

The operation panel 7a provided in the integrated amplifier 7 includes a liquid crystal display member for displaying each device,
Operating members such as touch switches and slide knobs for operating the device are provided in association with the liquid crystal display member.

On the back side of the integrated amplifier 7, a plurality of power outlets 7b are provided for connecting devices constituting the system and for supplying signal currents for operation.

This outlet 7b is provided with a switch 7c for passing current through the liquid crystal display member, and this switch 7c has a function of turning on only when a plug of the device or the like is inserted into the outlet 7b.

Therefore, when the plug of a system device is inserted into the outlet 7b, the switch 7c turns on and the device is displayed on the liquid crystal display, but if the device is not inserted, the switch 7c turns on.
Since it is OFF, no display is performed by the liquid crystal display member.

In FIG. 1, a compact disc player 4 is shown as a connected system device.

Therefore, the display on the display panel 7a is displayed only for connected system devices, and is not displayed for unconnected system devices, so the display is simplified according to the connection of system devices. Ru.

Next, an example of a connector having such a switch function will be described with reference to FIGS. 3 to 7.

Reference numeral 11 indicates a connector main body, in which a recessed portion 13 with a power connection pin 12 erected is provided in a part thereof, and a plug of a system device to be connected is inserted into this recessed portion 13, and the power line is connected to the connection pin 12. connection,
The ON-OFF switch for that device on the operation panel 7a of the integrated amplifier 7 connects or cuts off the power to that device.

This connector main body 11 has a built-in switch 14, and a part of an operating piece 15 that turns the switch 14 on and off protrudes into the recess 13, and when the power plug is inserted, the operating piece 15 is turned on and off. When the button is pressed, the switch 14 is changed over, and direct current is supplied to the liquid crystal display member, thereby producing a display (FIG. 5).

This connector body 11 is provided with another recess 16, in which a pin 17 and a contact piece 18 are provided,
By connecting the flag of a connected system device to this, a signal current for operating that device can be passed (Fig. 4).

In the above embodiment, the integrated amplifier 7 is provided with the operation panel 7a, but the operation device may be any other system device, and after detecting the connected device, it can be separated from the main unit and used as a remote control device. It may also be used as

[Effect of idea]

As described above, in the present invention, only the display members for connected system devices are displayed, and the display members for unconnected system devices are not displayed.

Therefore, when some system equipment is not connected, the number of displays is reduced and the display is easy to understand, eliminating the sense of complexity and fear caused by a large number of displays, and helping to prevent operational errors. It also becomes.

Furthermore, it is possible to prevent the illusion that an unconnected device is connected, or to operate its operation member.

Furthermore, since the operation panel can be displayed in each mode on an LCD, etc., the overall function display can be unified,
This also has the effect of enlarging the individual display area.
