That is, a lower base having a concave portion on the upper surface of a spherical surface and having a pillar protruding near the center of the concave portion, and a convex portion on a spherical surface having a bottom portion substantially fitted in the concave portion and having a convex portion with a diameter larger than that of the pillar. And a device main body having a groove having a slightly larger width so that the support column fits in the groove, and the support column connects the cable connecting to the device main body from the lower base through the inside of the support column. Is a display device with a rotation / tilt mechanism, in which the support column serves as a fixed shaft to rotate and tilt the device body, and the cable is a convex portion on the device body side. It is provided in the main body of the apparatus by being wound around the column several times and held therein, and having substantially the same shape as the internal shape of the convex portion that prevents the cable from overriding the column and being seen through. Hold down It has a member and a rotation restraining mechanism for restricting the device body from rotating more than a certain amount with respect to the lower base.

With this configuration, it is possible to protect the cable connecting the lower base to the apparatus main body, and it is possible to provide a small and lightweight display device with a rotation and tilt mechanism.

In the recess 3 formed on the upper surface of the lower base 1, a cross-shaped spacer 19 is placed as shown in FIGS. 2 and 3.
The cross-shaped spacer 19 has an engagement hole 20 at the center, which is slightly larger than the outer diameter dimension of the column 4 formed on the upper surface of the lower base 1,
It is made of wear-resistant resin with low friction coefficient,
The column 4 is placed on the upper surface of the lower table 1 through the engaging holes 20 of the spacer 19.

Next, as shown in FIG. 4, the apparatus main body 2 is placed so that the convex portion 10 provided on the bottom thereof fits into the concave portion 3 of the lower base 1. At this time, the cylindrical stopper 18 provided at the bottom of the apparatus body 2 is fitted into the groove 9 provided in the recess 3 of the lower base 1. In this state, the center of the inclined groove 11 and the center of the support column 4 are aligned. Next, as shown in FIG. 2, a plate made of a resin having a low friction coefficient and a low friction coefficient, which has a disc shape and has an engaging hole 21 slightly larger than the outer diameter dimension of the column 4 in the center thereof. 22 is mounted on the column 4 of the lower base 1 through the engagement hole 21.

As shown in FIG. 2, the cylindrical cap 23 is provided with a pair of mounting holes 24 on the upper surface with the same dimensions as the mounting dimensions of the pair of screw seats 7 of the column 4 of the lower base 1, and further has a notch on the side wall. twenty five
Is provided. The cap 23 is placed on the column 4 and fixed to the screw seat 7 through the mounting hole 24 with the screw 26 as shown in FIG. At this time, the dimensions of the cap 23 and the support column 4 are taken into consideration the thickness of the spacer 19, the thickness of the apparatus main body 2 and the thickness of the plate 22, and are smoothly slid in a state where they are securely fixed with screws. It is like this.
Furthermore, by fixing the cap 23, the signal cable
12 and the power cable 13, the notch 25 of the cap 23 and the column 4
It is designed to be firmly fixed with the notch 6 of the.

The signal cable 12 and the power cable 13 are wound around the cap 23 several times according to the rotation angle and the inclination angle of the device main body 2 and aligned so that the movements are constant, and the ribs 14 of the device main body 2 are aligned. It is pulled out and fixed from the guide hole 16 provided.

Further, as shown in FIG. 2, four locking holes 27 are provided at the positions corresponding to the locking claws 17 formed on the upper surface of the rib 14 of the apparatus main body 2, and the center thereof is a protrusion 10 at the bottom of the apparatus main body 2. Holding plate made of a transparent resin having a low friction coefficient and a high wear resistance, and having a semi-spherical convex portion 28 having a radius larger than the radius of
29, as shown in FIG. 4, the signal cable 12 and the power cable 13 which are wound around the device body 2 under a certain condition do not come out of the cap 23 due to the rotation and inclination of the device body 2. It is locked by a locking claw 17 formed on the upper surface of the rib 14 of the apparatus body 2.

In the display device with a rotation / tilt mechanism configured as described above, when it is desired to tilt the device body 2, when the cover 30 of the device body 2 shown in FIG. The protrusion 10 is the spacer of the recess 3 of the lower base 1.
The column 4 slides on the surface 19 and relatively moves along the inclined groove 11 at the bottom of the apparatus main body 2, so that the apparatus main body 2 is inclined at a desired angle.

Next, when it is desired to rotate the device body 2, when a force to rotate the device body 2 horizontally in the clockwise direction or the counterclockwise direction is applied, the protrusion 10 at the bottom of the device body 2 is above the recess 3 of the lower base 1. The surface of the spacer 19 is slid around the column 4 so that the device body 2 smoothly rotates at a desired angle. This rotation is
It is possible even when the device body 2 is tilted at a desired angle. However, if the device main body 2 is rotated 360 ° or more, the signal cable 12 and the power cable 13 are deformed more than necessary to cause troubles such as cutting. Therefore, the stopper 18 provided at the bottom of the device main body 2 is recessed in the lower base 1. The groove 9 provided in the place 3 is orbited in the range of the groove 9 and stopped by the rotation stopper 8. The device body 2 can be rotated to a desired angle within the range of the groove 9.

The display device shown in the above embodiment can be further miniaturized while having a rotation / tilt mechanism, and can be manufactured at low cost with a small number of components. Moreover, since the shapes of the parts are simple, the number of assembling steps can be significantly reduced. Since the display device that can be rotated and tilted can be downsized, the space can be saved and the degree of freedom of arrangement such as installation on a desk is increased. In this embodiment, when the width of the groove 9 provided in the recess 3 of the lower base 1 is not sufficiently large with respect to the diameter of the cylindrical stopper 18 provided at the bottom of the apparatus body 2, a large inclination is obtained. Performing an action may induce a rotational action.

The apparatus of the above-described embodiment is composed of the apparatus main body 2 and the lower base 1, and the apparatus main body 2 always has the rotating / tilting mechanism. As shown in FIG. 7, the apparatus main body 2 is separated from the lower base 1, and an upper base 31 that replaces the apparatus main body 2 is provided.
By moving the parts having the above structure and the parts to the upper base 31, it becomes a separate rotating / tilting device, and its application is further expanded.
