Description

  The present invention relates to a rack mount for mounting an electronic device on a system rack and an electronic device attached to the rack mount. More specifically, when a liquid crystal display or the like is used for a monitor, the display screen is set at an arbitrary horizontal angle. The present invention relates to a rack mount that can be set, and relates to an electronic device attached to the rack mount.

  In recent years, liquid crystal displays have been widely used, and are also used for monitors in relay vehicles such as television relays. Although the liquid crystal display has the advantage that the display screen can be enlarged and reduced in weight, it has the disadvantage that the viewing angle is relatively narrow. In particular, the space for the adjustment room in the relay car is narrow, and the liquid crystal display is the operator. The display screen and the operator make an acute angle, making it difficult to see the display screen.

  6A and 6B show a liquid crystal panel using a conventional liquid crystal display, in which a plurality of liquid crystal panels 1 are arranged in a frame 2 and are integrally provided in a box 3. A tilt mechanism is provided in the part. The box 3 is provided with an ear 4 for mounting on the front column of the system rack. The display screen of the liquid crystal panel 1 can be rotated within a range of tilt angles Qa and Qb with respect to the horizontal center line Ca of the frame 2 by a tilt mechanism. This liquid crystal panel was able to adjust the tilt angle (vertical angle) by a tilt mechanism (see, for example, Patent Document 1).
