Description

  The present invention relates to a small-sized electronic device that is used by being mounted on, for example, an upper portion of a flat display frame such as a liquid crystal display or a plasma display, such as a remote control light receiver or a so-called WEB camera.

  In recent years, the present inventors have developed an AV (audio / visual) data transmission system that digitally compresses video signals and audio signals and wirelessly transmits them. According to such a system, for example, video data and audio data are transmitted wirelessly in a state where the recording / playback device and the display are installed at locations separated from each other, thereby separating the video and audio played back by the recording / playback device. It becomes possible to output on the display of the place.

  In such an AV data transmission system, a remote control receiver is installed in the vicinity of the display so that the user can operate the remote control of a recording / playback device installed at a remote location with the user facing the display. Thus, the remote control signal can be received. Then, such a remote control light receiver is connected to the transmission system via a cable, and the remote control signal is transmitted wirelessly to the recording / playback device via the transmission system.

  These remote control receivers are stable at various locations such as the upper part of flat display frames such as liquid crystal displays and plasma displays, the upper part of thick display frames such as CRT receivers, and the edges of AV racks. It is required to be installable.

  Further, even in a small-sized imaging apparatus such as a so-called WEB camera that is cable-connected to a personal computer or the like and outputs an imaging signal from the imaging camera via a cable, it is generally fixed to the upper part of the display.

Conventionally, for example, Patent Documents 1 to 4 disclose the following techniques as a fixing structure of a small imaging device (video camera) as described above. In other words, a lever part that can be inserted and removed is provided in the lower fixed part of the video camera. When installing on a thin display, the lever part is taken out and fixed so as to hold the display by a clip method, while it is installed on a cathode ray tube display. In some cases, a structure is disclosed in which the lever portion is hidden and the fixing portion is fixed so as to be placed on the display. Patent Document 5 discloses a technique in which an infrared light receiving unit is provided in a rotatable state on the right frame of a liquid crystal panel.

  In recent years, even with flat-shaped displays, there are various methods such as liquid crystal displays, plasma displays, rear projection displays, etc., and the screen size is also diverse, so the thickness of the upper part of the frame of these displays is Not constant.

  Therefore, when a clip-type method is applied as a method for fixing a small electronic device to the upper part of the display frame, the clip opening / closing width must be increased to accommodate various frame thicknesses. There was a problem that the structure of became large.

  In addition, in the fixed structure as shown in Patent Documents 1 to 4, when the top plate at the top of the display is flat and wide like a CRT display, or the thickness of the top of the frame such as a medium screen size liquid crystal display matches the clip. The video camera can be fixed stably if the size is too large, but the center of gravity does not match the position of the center of gravity with a flat display with a thickness that does not fit the clip, such as a large-screen plasma display. There was a problem that sometimes it could not be fixed.

  An object of the present invention is to provide a small electronic device having a compact structure and a fixing structure that can be stably fixed by appropriately adjusting the thickness of the fixing portion from a thin one to a thick one.

Thus, it is possible to stably fix a small electronic device even at a small depth. In addition, if the clip-type fixing structure is used to cope with various thicknesses of the fixing part, the structure of the fixing part becomes large. However, in the method of the present invention, it is possible to cope with various thicknesses of the fixing part with a compact structure. I can do it.

Preferably, at the tip of the portion extending downward of the rotating arm, at least the side where the rotating shaft is located has a coefficient of friction larger than that of the member surface of the rotating arm, and the rotating shaft is larger than the tip portion of the rotating arm.

You can also Therefore, such a setting can be performed by the link release mechanism.

  Specifically, the above-described small electronic device receives an infrared signal, converts the infrared signal into an electrical signal, and outputs it to an externally connected device via a cable (for example, a remote control receiver). In addition, the present invention is useful when applied to an imaging apparatus (for example, a so-called WEB camera) that includes an imaging camera and outputs an imaging signal from the imaging camera to an externally connected device.

  As described above, according to the present invention, the structure of the fixing mechanism can be made compact, and the opening and closing amounts of the two rotating arms can be appropriately adjusted according to the thickness of the fixing part of the article edge to stabilize the small electronic device. There is an effect that can be fixed.
