At the left and right central portions of the rear upper rail 6, a cylindrical cushion member 24 made of foamed rubber or foamed plastic is externally fitted to provide cushioning properties.
This cushion material 24 extends between the left and right of the rear upper beam 6,
Alternatively, it may be mounted separately at several locations on the left and right.

The display D is supported by the base plate 26 in a front-up inclined posture. The base plate 26 for that purpose is supported by the front beam 5 and the rear lower beam 7. That is, the base plate 26 is made of a metal panel whose upper surface is finished flat and whose four peripheral edges are folded toward the lower surface, and two reinforcing frames 27, 27 having hat-shaped cross sections are fixed by welding to the left and right side edges of the lower surface. I have. As shown in FIG. 4, an Ω-shaped connecting metal fitting 28 for holding the rear lower rail 7 is fastened and fixed to the lower surface of the rear end of each of the reinforcing frames 27. It is pivotally connected to the bar 7. Further, a slide frame 29 bent in a hat shape is screwed to the lower surface of the front end of each reinforcing frame 27 and fastened.
By passing the front beam 5 between the base plate 2 and the reinforcing frame 27,
The front end side of 6 is received and supported by the front crossbar 5 so as to be movable forward and backward.

The inclination angle of the base plate 26 can be changed by changing the vertical position of the rear lower beam 7 with respect to the rear support 12. Therefore, as shown in FIG.

Is defined as a fastening hole 30 for the rear lower bar 7, and the holes from the top hole to the fourth lower side are defined as the fastening holes 31 for the rear upper bar 6.

In the rack constructed as described above, a printer P or a plotter is mounted on a top plate 2 as shown in FIG. 2, a keyboard K is mounted on a table 3, and a display is further mounted on a base plate 26. D is placed and used. Since the left and right width of the table board 3 is sufficiently larger than the left and right width of the keyboard K, the upper surface on one side can be used as an operation surface of the mouse. An external memory device such as a floppy disk drive can be mounted on the side plate 18. On the bottom plate 4, a print paper for the printer P, a hard disk, and the like are arranged.

The screen size of the display D varies depending on the computer system used, and the position and angle of the screen which are easy to see differ depending on the sitting height of the user. In order to support the display D at an ergonomically favorable position and angle in this way, the fixing position of the rear lower beam 7 with respect to the rear support column 12 is changed up and down, and the inclination angle of the base plate 26 is changed to be large or small. . In this example, as shown by the imaginary line in FIG. 2, the maximum inclination angle is set to about 30 degrees, and the inclination angle can be changed in a total of five steps between this position and the position where the base plate 26 is horizontally supported. I made it. Since the base plate 26 is at a position lower than the table board 3 even in the horizontal support state, the screen position can be lowered to reduce the amount of movement of the line of sight between the keyboard K and the screen.

The front and rear dimensions of the display D differ depending on the screen size, and the front and rear dimensions differ depending on the maker even for the same screen size. In order to support the display D at an optimum position corresponding to such a difference in dimensions and further adjust the front and rear positions of the display D in each inclined state, the fixing position of the rear upper bar 6 with respect to the rear support 12 is changed up and down. For example, when the fixed position of the rear upper rail 6 is changed to either the upper or lower position with reference to the state shown by the solid line in FIG. 2, the display D is received by the rear upper rail 6 via the cushion material 24 at the position where the display D has moved to the rear of the rack. Supported. Therefore, the base plate 2
The position and angle of the screen of the display D can be variously changed and optimized by the combination of the inclination angle of 6 and the receiving position of the rear upper rail 6.

According to the computer rack of the present invention, the inclination angle of the base plate 26 can be changed by changing the fixed position of the rear lower beam 7 with respect to the rear support 12 up and down.
The user can improve the usability by changing the position and angle of the screen to a suitable state according to the user's preference, the difference in sitting height, the size of the display D, and the like. Since the inclination angle of the base plate 26 can be changed by using the front crosspiece 5 and the rear lower crosspiece 7 which are the reinforcing structural members of the rack, a rack having an angle adjustment function can be obtained while the rack structure is simplified. Therefore, a sufficient cost reduction effect can be obtained as compared with the conventional rack.

After the rear surface of the display D is received by the rear upper bar 6, the position of the rear upper bar 6 fixed to the rear support 12 is changed up and down, so that the front and rear position of the display D can be changed. The display D is adjusted by adjusting the inclination angle of the base plate 12 and adjusting the receiving position of the rear upper rail 6.
It is also advantageous in that the angle and position of the screen can be changed and adjusted in various ways, and fine adjustments can be made according to the user's preference and height differences.
