In addition, such a display is installed in front of the stand base of the display supporting device so that the angle can be adjusted freely, so that the daytime direction of the display can be changed according to the user's straightness. As an example of a conventional display supporting device, there is a lifting device for a liquid crystal display disclosed in Patent Registration No. 3063920. In the lifting device of the liquid crystal display, as shown in FIG. 丨 丨, the upper part of the front surface of the pedestal base 200 capable of adjusting the lifting in the height direction XI is provided with a first supporting mechanism 201A to support the liquid crystal display 300 to enable it to rotate freely in the 90 ° rotation direction X2 around the central axis 0; and a second support mechanism 2 0 1 B to support the liquid crystal display 3 00 so that it can be tilted and rotated above the horizontal axis 0 Turn freely in direction X3. However, in the liquid crystal display lifting device disclosed in the aforementioned patent publication, as long as the main body of the pedestal base 200 cannot be rotated horizontally, the liquid crystal display 300 cannot be tilted to rotate around the vertical axis (not shown). 1Support mechanism 201A and 2nd support mechanism 2〇 ^, because

2036-4542-PF; ahddub.ptd Page 5 521220, Description of the Invention (2) = The mechanism formed by other groups, so as the LCD display 300 angle and angle direction increase, the number of components will also increase Therefore, it is difficult to suppress the increase in the number of parts.

In addition, the horizontal axis of the rotation center p, which is the tilting direction X3 of the LCD display 300, is “behind the LCD display 300”, so even if the LCD display 300 is to be tilted up and down By moving a small angle in the direction χ3, the moving distance of the liquid crystal display 300 in the tilting rotation direction χ3 also becomes large. Therefore, when adjusting the angle of the liquid crystal display 300 in the up-down tilt rotation direction x3, it is necessary to adjust the height direction XI of the stand base 200. In addition, since the direction of the liquid crystal display 300, the horizontal axis 01 which becomes the rotation center ρ will deviate from the center of gravity G of the liquid crystal display 300. Therefore, when the user wants to adjust the direction of the liquid crystal display 300, the operating force is not constant. Also, when the liquid crystal display 300 has a certain weight, it is difficult to stably mount the liquid crystal display 300 without the addition of a spring or the like. In addition, if the vibration occurs, the liquid crystal display 3 is easily displaced.

2036-4542-PF; ahddub.ptd Page 15 521220 V. Description of the invention (12) The restricting member 5 has a plate-like body portion 51 having approximately the same periphery as the plate portion 4 i of the flange 4. Furthermore, through-holes 52, ~, and 52 角度 are formed in the four corners of the body portion of the angle-limiting member 5, and the positions of the respective through-holes 52, ~, and 52 are connected to the fourth plate portion 41 of the flange 4 Corresponding to the through-holes 43, ~, and 43 at the corners. Further, screws are inserted into the through-holes 43, ~, and 43 formed in the flange 4 and the through-holes 52, ~, and 52 formed in the angle limiting member 5. B, ~, B, these screws B, ~, B are screwed into screw holes (not shown) formed on the rear surface of the display D shown in Fig. 4. As a result, the flange 4 and the angle limiting member 5 It is fixed in a state of being integrated with the display D. Further, on the rear surface of the angle restricting member 5, four stopper protrusions 5 3A constituting a part of the stopper 6 and protruding toward the rear are formed. , 53B, 5 3C, 53D. These stopper protrusions 53A, 53B, 53C, 53D all have the same protrusion amount, and the protrusion amount is set as shown in FIG. 3, although it can be formed at The stopper wall portions 33A, 33B in the front of the cover support 3, but the reinforcement ribs 34 cannot be reached.

521220

5. Description of the invention (13) shows that the screw 8 is screwed in. The screw has a threaded portion 8 B on the end. The head 8 A of this thread is slightly flat at the back, and it is installed in a state where the thread is contracted between the receiving parts 35. A head 8A having a larger diameter and a portion 8 B formed by the nut 30 are screwed in. The spring 8 of the screw 8 is behind this and the cover support 3. The coil spring 9 is slightly retracted here. Since the screw 8 is screwed in by the nut 30, it is in a fixed state with respect to the base member 2. Therefore, the coil spring 9 is extended by taking a reaction force from the head 8A of the screw 8. The lid body 31 of the lid support 3 is pressed toward the partition plate 22 by the pressing force of the coil spring 9 at this time. When the cover body 31 is pressed toward the partition plate 22, the spherical surface portion 42 of the flange 4 disposed between the cover body 31 and the partition plate 22 is held. In this way, the flange 4 is held by the base member 2 and the cover support 3 so as to be able to slide in any of the following directions, as shown in FIG. 2 and FIG. 90 ° rotation direction X2 of axis 0; tilting rotation direction X3 about the horizontal axis 01 up and down; and left and right tilting rotation direction X4 about the vertical axis 02. Hereinafter, the orientation adjusting device 针对 of the display of the present invention having the above-mentioned configuration will be described. In the display direction adjusting device Η, the flange 4 is held between the receiving surface 27A of the partition plate 2 2 and the rear surface of the cover support 3, and the display D is held on the flange 4 through an angle limiting member 5. The flange 4 can slide along the receiving surface 2 7 A. As a result, the display D mounted on the flange 4 is in the direction of 90 ° rotation direction X2 around the central axis 0; the tilt rotation direction X3 around the horizontal axis 01; and the left and right tilt rotation direction X4 around the vertical axis 02. Rotation, both

2036.4542-PF; ahddub.ptd Page 17 521220 V. Description of the invention (14) This display mounting section 1 can be implemented. Next, a description will be given of a rotation operation of the display D in a 90-degree rotation direction χ2 around the central axis 0. First, as shown by an imaginary line in FIG. 5, any one of the stopper projections 53B and 53D of the angle restricting member 5 abuts against any one of the stopper wall portions 33B and 33A, and rotates. Will be restricted. Now, in this state, the display D shown in FIG. 4 is regarded as an object facing the horizontal direction. When the display D is to be oriented vertically from this state, if the display D is rotated relative to the central axis shown in FIGS. 2 to 4 as the needle rotates at the same time, the angle limiting member 5 will also be as shown in FIG. 5. As shown in the figure, the rotation direction of the 90-degree clockwise rotation relative to the central axis 0 is rotated. Moreover, when the display D is rotated 90-degrees at the same time, the stopper projections 53A, 53C of the angle limiting mechanism are at this time. If any one of them abuts against any one of the stopper parts 33A and 33B, the rotation will be restricted. At this time, the edge 4 is the same as the angle limiting member 5 and rotates just as it turns to 9 〇degree, the rotation will be limited. As a result, the display D that was originally horizontal can be turned into a vertical direction. Next, the up-down tilt direction of the display D around the horizontal axis 〇1 will be described as shown in Figure 6 ' The flange 4 is a body support 3 ′ with respect to the base member 2, although it can be positioned on the horizontal axis as shown in FIGS. 2 to 4.

The device dΛ turns Λ μ but its rotation range is limited. That is, the flange 4 and the angle limiting member 5 are placed in the middle position of the solid line ^ by the display = rotation around the horizontal axis 01, and tilted to the horizontal direction as shown in FIG. 6 Turn it counterclockwise so that it faces downward. 'Angle-restricting member 5 The lower part of the main body 51

521220 V. Description of the invention (15) The surface ′ will abut against the wall portion 3 3 B of the stopper on the lower side of the cover support 3. In this way, the rotation range of the flange 4 and the angle restricting member 5 is restricted. By this, the direction of the tilting rotation direction x 3 of the display D can be changed. Here 'when the body portion 51 of the angle restriction member 5 is directed downward,

The stopper projections 5 3D above it do not abut against the stopper wall portion 33A of the lid support 3. However, when the stopper projection 53D located above the angle restricting member 5 does not abut the stopper wall portion 33A of the cover support 3, the stopper projection 53B below the angle restricting member 5 abuts. The stopper wall portion 3 3β below the lid support 3. In this state, the stopper projection 53β below the angle limiting member 5 may hit the reinforcing rib 34 of the lid support 3. However, as shown by the dotted line in FIG. 6, the protruding length of the reinforcing rib ^ is very short. Even when the stopper projection 53B is closest, the reinforcing rib 34 and the stopper projection 53B are set so as not to touch Here. Similarly, the other bumper protrusions 53A, 53C, and 53D are also set so as not to hit the reinforcing ribs 34 even when they are closest to the front surface of the cover body 31.

In this way, when the body portion 51 of the angle restriction member 5 is facing downward, the stopper protrusion 53B and the stopper wall 33B below the angle restriction member 5 can restrict the angle restriction member 5 and the flange 4 from moving downward. On the other hand, when the upper rotation range of the angle restriction member 5 is directed upward, the stopper protrusion 53β below the angle restriction member 5 is not connected to the stopper wall portion 33B. However, Shade restricting structure; 53D of the device projection is abutted against the wall portion of the stopper above the cover support 3 by 3jA. In this way, when the body portion of the angle restricting member 5 "is facing upward, the stopper projection 53D and the cover supporting the upper portion of the angle restricting member 5 are staggered."

V. Description of the invention The stopper wall portion 33A of (16) 3 can limit the downward rotation range of the angle limiting member 5 and the flange 4. In this state, for example, when the display 〇 is to be portrait, and when the display D is horizontal, as shown by the solid line in FIG. 5, the stopper projection 53A is arranged at the top, and the stopper projection is convex. The 53C series is located below. Furthermore, the same effect as the stopper projections 53D, 5 3B can restrict the rotation of the display device 0. Furthermore, by providing a stopper at a position just rotated by 90 degrees, the display D can be easily set to portrait or landscape orientation. In addition, in the display shown in FIG. 4], when the stopper protrusion is not provided in the turning operation of the left-right tilting rotation direction X4 around the vertical axis 〇2, the display D is opposed to the surrounding horizontal axis. 1 The rotation in the up-down tilt rotation direction is the same, but when the stopper protrusion is provided, the rotation of the display device D around the vertical axis θ2 in the tilt rotation direction χ4 will be restricted. The display direction adjustment device Η, by using the base member 2 and the cover support 3 in the display mounting portion 1 only with the holding flange 4, enables the display D to rotate in a 90-degree rotation direction χ2, and tilt the rotation direction Xj and Tilt left and right to turn in direction X4. Therefore, since it is not necessary to separately provide the support mechanism 'in order to correspond to all the turning operations of the display!), The number of parts can be reduced. Further, in the display direction adjusting device Η of the present invention, the flange 4 sliding along the receiving surface 27A of the partition plate 22 of the base member 2 is tilted up and down: to the center P of rotation (refer to FIG. 6) 'The system is located more squarely than the receiving surface 27A. Therefore, the flange 4, the angle limiting member 5, and the display 521220

V. Description of the invention (17) The device D rotates with a point further forward than the receiving surface 27 A as the center. Therefore, when the display is rotated in the up-and-down tilt rotation direction X3, the moving distance in the up-down direction can be smaller than the previous object. ^ Furthermore, by making the rotation center ρ when the flange 4 rotates, the rotation center ρ is located approximately in front of the receiving surface 27A, and this rotation center ρ can be made to approximately coincide with the center of gravity of the display 07.
