Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a display device with a rotating/tilting mechanism, and is particularly applicable to a CRT display device such as a desk-mounted office computer or a personal computer, and is applicable when used by a large number of people or when used face-to-face. The present invention relates to a display device with a rotating/tilting mechanism suitable for cases where the device is used by a group of people.

[Conventional technology]

As a display device with a rotating/tilting mechanism that improves operator operability, for example, Japanese Patent Application Laid-Open No. 59-216222
As shown in FIG. 1 of the publication (FIG. 8 of the present application), a cable 33 for transmitting signals, power, etc. to a display device 32 is connected to a lower table 34 and a rotary table 35 that can rotate horizontally on the upper surface of the lower table 34. It is known that the display device is guided through the interior of a display device with a rotating/tilting mechanism, which consists of an upper table 36 that can be tilted on a rotating table 35. This device simply combines a rotating mechanism and a tilting mechanism that are independent of each other. Although the cable 33 processing and rotation stopper mechanism are simple, there are problems in that it has many components, is expensive, and is difficult to assemble. Furthermore, since there are many component parts, there is a problem that it is not possible to reduce the size and weight.

Furthermore, as a mechanism that integrates the rotation and tilting of a display device, a structure for adjusting the angle of a display device described in Japanese Utility Model Application Publication No. 149779/1980 is known.

In this prior art, rotation and tilting of the display device is performed by movement in one plane between the bottom surface of the display section and the top surface of the support section. In such conventional technology, if the center of gravity of the display unit and the center of the convex spherical surface on the bottom of the display unit do not perfectly match, when you try to rotate the display unit from side to side, the coefficient of friction decreases at the same time as the rotation, and the rotation While this is being done, a tilting action takes place, and when it is rotated from point A to point B as shown in FIG. 10, the horizontal state at point A becomes tilted at point B. Therefore, there was a problem in that the inclination had to be adjusted again after rotation.

[Problem that the invention seeks to solve]

The conventional technology has the above-mentioned problems.

The purpose of the present invention is to reduce the number of component parts by integrating the rotation and tilting mechanisms, whereas the conventional structure consisted of two mechanisms: rotation and tilting. This provides a device with good operability.

Another object of the present invention is to perform rotation and tilting operations in a mechanism that integrates rotation and tilting functions by sliding them on different surfaces, instead of performing them by sliding on the same plane. By doing so, each operation is separated and independent, and the center of gravity and rotation of the device body are
To provide a display device that can reliably and smoothly perform rotation and tilting operations even if the centers of the tilting mechanisms do not coincide.

[Means for solving problems]

In order to achieve the above object, the present invention provides a display device body in which a spherical convex portion is formed on the bottom and a long inclined groove in the front and back direction near the center of the convex portion, and a spherical concave portion on the top surface. is formed, a lower platform having a pillar protruding near the center of the recess, a recess on the upper surface of the lower platform,
It is sandwiched between the protrusions on the bottom of the display device main body, and has an engagement hole into which the support column is rotatably fitted, and when the display device main body is slid back and forth along the slanted groove. is fixed relative to the lower base, and the other surface slides against the convex part of the display device main body, and when the display device main body rotates, the other surface is fixed relative to the display device main body. It has a slider that is fixed to the base and has one side that slides into a recess in the lower base.

[Effect]

It has a structure that allows movement in two planes: rotation at the fitting part of the lower stand and slider, and tilting at the fitting part of the slider and device body, and the center of gravity of the device body is not aligned with the center of the convex part on the bottom. Also, rotation and tilting operations can be performed reliably and smoothly.
