Description

TECHNICAL FIELD The present invention relates to an electric / electronic device, and particularly to an electric / electronic device such as an audio mixer.

Conventional technologyElectrical / electronic devices such as audio / mixers should be used on a desktop or a dedicated table with the operation panel facing horizontally upward, or should be mounted on a rack together with other peripheral devices so that the panel surface is vertical. The connection terminals, which are connected to a large number of other devices in order to enable either use, have a structure provided on the front part or the back part when the operation panel surface is the top surface.

However, when using electrical / electronic equipment such as conventional audio / mixer with other equipment such as a rack so that the operation panel surface is vertical, it is necessary to add extra space to the operation panel surface. If you try to mount it in a rack so that the connection will not occur, the connecting terminals will be close to the housing of other devices placed at the top or bottom.Therefore, connecting cords can be attached to or detached from the terminals while mounted in the rack. Since it is not possible or it becomes very difficult, place a device that often attaches and detaches connection cords such as an audio mixer at the top, and the terminals attach and detach the cords at the top, and the terminals are Since there was a space between the equipment to be mounted on the provided surface and the equipment so that there would be no hindrance to the connection, in some cases it would be inconvenient to operate, or there would be unnecessary space on the rack surface. There were problems such as the need for space.

Also, when using the desktop, since each operation knob comes to the front end of the panel, it is impossible to fix the hand during operation, so the position of the hand becomes unstable, fine adjustment becomes difficult, and the wrist is easily tired. There was a problem.

The present invention has been made in view of the above points, and an object thereof is to provide an electric / electronic device that solves the above problems by enlarging the operation panel surface in some cases.

Means for Solving the Problems The present invention relates to an electric / electronic device in which a connection terminal for electrically connecting to another device is provided on a front surface or a back surface of a housing having an operation panel surface as a flat surface. Alternatively, a pad device that is detachably locked to the back surface and expands the operation panel surface is provided on the front surface or the back surface.

Action For example, in the case of an electric / electronic device that has a connection terminal on the back side and is used for both desktop and rack mount, when the operation panel surface is used vertically with rack mount etc. and another device is to be placed on top of it, a pad device By providing the back portion, an appropriate space can be provided between the device and another device, and cords can be connected to the connection terminal while being rack mounted. Further, when the operation panel surface is horizontal and is used on a desktop, a pad device is provided on the front surface so that it can be used as a pad for fixing a hand during operation.

Embodiment FIG. 1 shows a perspective view of an embodiment of the present invention. In the figure, 1 is an audio mixer main body, and 2 is a pad device.

In this embodiment, the audio mixer body 1 is provided on the operation panel surface 3
This is an example of using it on the desktop with the arrow pointing up. The operation panel surface 3 of the audio mixer main body 1 has a rear portion 5 which is higher than the front portion 4 and is slightly inclined forward. Connection cords 8 from other devices are connected to an end supporting portion (not shown) provided on the back surface portion 5.
The operation panel surface 3 is provided with adjustment knobs 6 and 7 such as a volume lever for adjusting the output level of an input audio signal from another device input from the rear surface 5.
The adjustment knobs 6 and 7 are arranged up to near the front end of the operation panel surface 3. Further, the pad device 2 is attached to the front surface portion 4 with screws or the like.

As shown in FIG. 3, the pad device 2 is formed by winding a pad 10 of rubber, soft plastics or the like on the upper surface and the side surface of an angle portion 9 having a U-shaped cross section. The mounting surface 11 is provided with a notch 12 for mounting, and by screwing a screw into the housing of the audio mixer main body 1 through the notch 12, the pad device 2 is formed by the screw and the housing.
Is clamped and fixed to the audio mixer body 1.

Further, as shown in FIG. 2, the audio mixer main body 1 is rack-mounted so that the operation panel surface 3 is vertical, and other devices are also mounted on the upper and lower portions thereof. At this time, the pad device 2 is attached to the back surface 5 of the audio mixer body 1. Therefore, since an appropriate space can be maintained between the audio mixer main body 1 and another device mounted on the upper portion of the audio mixer main body 1, terminals, connectors, and connection cords provided on the rear surface 5 of the audio mixer main body 1 can be maintained. The audio mixer main unit 1 can be attached to and detached from the audio mixer main unit 1 while being mounted on the rack, and when the device mounted on the rack is viewed from the operation panel surface 3 side, the audio mixer main unit 1 and the device mounted on the upper part thereof can be connected. There is no extra space between them.

In the case of using the desktop as shown in FIG. 1, since the pad device 2 can fix the hand to the pad device 2 when the adjustment knob 7 is operated, the operation is easy and the operation is stable. , Reliable operation becomes possible.

In addition, the pad 10 on the operation panel surface side of the pad device 2 is made of a transparent plastic plate or the like to correspond to the respective adjustment knobs 6 and 7 both when used on a desktop and when used in a rack mount. The adjustment knobs 6, 7 etc. can be easily identified by pushing the card on which the part name, number, etc. are filled in between the transparent plastic plate and the angle part 9 or by providing the pad 10 with the display part 13 by printing or the like. It becomes convenient for use.

In this embodiment, the pad device 2 is attached to the audio mixer main body 1 with screws, but the present invention is not limited to this.
It is also possible to adopt a configuration in which an engaging portion that engages with this rail is provided and the engaging portion of the pad device 2 is slid and fixed to this rail.

Note that printing, card insertion,
When the display unit 13 for identifying the adjustment knob is provided by a method such as engraving on a plastic plate, if the same pad device 2 is used both when the desktop is used and when the rack mount is used, the display for identification is reversed. Therefore, be careful. At this time, when the card is inserted, it is convenient that the display is not reversed when the desktop is used and when the rack mount is used by replacing the card.

Further, it is also possible to provide a hole in the display portion 13 of the angle portion 11 and illuminate from the back surface with a light emitting diode or the like.

Effect of the Invention As described above, according to the present invention, the operation panel surface can be enlarged by the pad device, and the operation panel surface is made horizontal so that it can be used as a pad for fixing the hand when operating on a desktop. It can be used and can be used as a spacer to keep the gap with other devices when used in a rack mount with the operation panel surface vertical, and in practical use, it can greatly improve operability. Have.
