Further, in the upper half portion of the back plate 4, a large number of through holes 4d are provided to form ventilation holes 4e. In this embodiment, the back plate 4 is detachably mounted. However, the back plate may be fixed between the legs 3. In this case, the fastening mechanism described below is
What is necessary is just to comprise so that work can be performed from the front side of the desk main body 100A, ie, the use end 2a side.

The display stand 5 is set so that the display DSP can be placed on the display screen obliquely upward and forward, and can be pulled out toward the use end 2a side of the top plate 2 as described later. Until it is fixed by the fastening mechanism FM, it is configured to be self-supporting and need not be supported.
The depth dimension is set to be slightly larger than about 1/2 of the depth of the top plate 2 and the width dimension is set so that the display DSP can be mounted with a margin. With such a depth dimension, when the display stand 5 is fixed to the deepest part of the desk main body 100A, a sufficient lower limb space can be formed on the front side of the display stand 5.

Specifically, the display stand 5 is
Left and right side plates 5a, a lower inclined plate 5b erected between the side plates 5a and supporting the back surface of the display DSP, and a front inclined plate 5c similarly supporting the bottom surface of the display DSP
A blind plate 5 attached above the front inclined plate 5c so that the display DSP cannot be seen from the front horizontal direction.
d, and an adjuster 5e attached to the left and right side plates 5a to adjust the height. Near the upper and lower ends of the rear end surfaces of the left and right side plates 5a, an insert nut 5f, which is one of the fastening members constituting the fastening mechanism FM, is embedded. The display stand 5 is fixed to the desk body 100A by screwing the bolt 11b to the insert nut 5f. The position of the insert nut 5f matches the position of the through hole 12 formed in the structural member 10. Moreover, since the adjuster 5e is provided, the alignment with the through hole 12 can be finely adjusted. The fastening mechanism FM is composed of the insert nut 5f, the structural member 10, and the bolt 11b. The lower inclined plate 5b and the front inclined plate 5c fixed between these side plates 5a are orthogonal to each other because the front edge of the lower inclined plate 5b and the rear edge of the front inclined plate 5c are in close contact with each other. Is fixed at a position inclined forward by about 30 ° from the vertical position. At a substantially central position in the left-right direction of the lower inclined plate 5b, a lead-out opening 5g for passing a power cord and a signal cable of the display DSP is provided. The lead-out opening 5g is provided above the lower structural member 10 so that cables derived from the lead-out opening 5g can be easily led onto the code duct 13 attached on the lower structural member 10. Has become. Note that the fastening mechanism FM is not limited to the above-described one, and a mechanism widely used in the relevant field can be applied.

The CPU stand 6 is a box having a shape close to a rectangular parallelepiped, and includes left and right side plates 6a, an upper plate 6b connecting upper end portions of the left and right side plates 6a, a lower plate 6c on which a computer main body is mounted, and an adjuster 6d. And This CPU
The depth of the stand 6 is about 1/2 of the depth of the top plate 2
The computer body can be stored in a storage space SP defined by the left and right side plates 6a, the upper plate 6b, and the lower plate 6c. Hook holes 6e for attaching the hooks F are provided on the outer surfaces of the left and right side plates 6a.

In such a configuration, the display D
The operation of mounting the SP on the display stand 5 will be described. First, the display stand 5 is moved to the desk body 10.
It is pulled out to a wide area on the front side of 0A where it is easy to work (Fig. 7). Since the display stand 5 is independent at the pulled-out position, the worker can work only by supporting the display DSP. Next, display DS
P is moved from above the display stand 5 to above the front inclined plate 5c, and in contact with the front inclined plate 5c, a power cord and a signal cable protruding from the back of the display DSP are led out of the lower inclined plate 5b through an opening 5g. Through. Thereafter, the display DSP is moved along the front inclined plate 5c to a position where the back surface of the display DSP is in close contact with the lower inclined plate 5b. Since the width of the display stand 5 is larger than the width of the display DSP, the position of the display stand may be finely adjusted so that the center of the display screen of the display DSP coincides with substantially the center of the front inclined plate 5c in the width direction. In this case, the work space is sufficiently large as compared with the space US below the top plate 2 of the desk body 100A, so that the work can be completed without an unreasonable posture.

Thereafter, the display stand 5 is carried into the space US below the top plate 2 of the desk body 100A. At this time, the back plate 4 is removed. Then, the rear surface of the side plate 5a of the display stand 5 is moved to a position where it comes into close contact with the upper and lower structural members 10, and the left and right positions and the height position are adjusted so that the insert nut 5f and the through hole 12 are aligned. The height position can be easily adjusted by rotating the adjuster 5e attached to the side plate 5a. The power cord and the signal cable coming out of the display DSP are placed on a code duct 13 attached to the structural member 10. When the insert nut 5f and the through hole 12 match, the display stand 5 is fixed to the structural member 10 by screwing the bolt 11b into the insert nut 5f and tightening. Since this fixing work is performed with the back plate 4 removed, it can be easily performed unlike the work in a narrow space.

On the other hand, the CPU stand 6 is
After placing the computer body on the lower plate 6c before A,
It is moved to the space formed between the display stand 5 and the leg 3. Since the CPU stand 6 has a switch and a floppy disk insertion slot on the front of the computer main body, the front of the CPU stand 6 is aligned with the front edge of the top plate 2 and the desk main body 100A like the display stand 5.
Do not carry deep into At this position, the CPU stand 6
The rear end substantially coincides with a position where the wiring port 9 exists. Accordingly, the wiring cap 9a is removed, and a cable from a keyboard and a mouse (not shown) on the top board 2 is introduced to below the top board 2 through the wiring port 9 and connected to the computer main body. At this point, the power cord and the signal cable placed on the code duct 13 are connected to the computer body. After connection and arrangement of the display DSP and the computer main body are completed as described above, the back plate 4 is fixed between the left and right legs 3.

After engaging the notch 4b with the pivot pin 14 from behind, the back plate 4 is rotated forward to move it to a position where it contacts the bracket 15. Then, the bolt 11a is inserted into the mounting hole 4c, and the bolt 11a is screwed into the female screw hole 16 of the bracket 15 and tightened.
Is fixed.

As described above, the display stand 5 can be pulled out to a place away from the desk main body 100A, and the work of mounting the display DSP can be performed at that position. When the display stand 5 is fixed, the back plate 4 is removed. Since the work can be performed in the state, the burden on the worker can be reduced. Further, since the display stand 5 is fixed to the structural member 10, the display DSP can be surely prevented from being displaced even though the display stand 5 can be pulled out (moved). Further, since the rear plate 4 can be removed, the connection operation for connecting the display DSP and the computer main body can be facilitated, and the operation time can be reduced. Back plate 4
After the notch 4b is engaged with the pivot pin 14 of the leg 3, it can be fixed by rotating it forward, so that the attaching / detaching operation can be performed in a short time. Further, since the rear plate 4 is fixed to the legs 3 via the rotation mechanism RM, the rear plate 4 is moved rearward, for example, when performing maintenance or inspection of the display DSP or adding wiring. The work can be performed only by slightly turning the upper part and opening only the upper part.

At the time of use, since the front inclined plate 5c is provided, the position of the display stand 5 does not shift even when the user's feet abut, and the display D
It is possible to prevent a problem that the display screen of the SP is shifted and the usability is deteriorated. This is particularly effective when a child uses the desk 100 in a study cram school or the like. Also, since there is a blind plate 5d, the desk 100 can be used at the time of use.
, The light of the display DSP leaking from below the top plate 2 can be reliably blocked.
This eliminates unnecessary light, so that it is possible to concentrate on viewing the display screen of the display DSP through the window 1.

The present invention is not limited to the embodiment described above. For example, in the above embodiment, the back plate 4 is detachably mounted.
The back plate may be constituted by two plates of the same size, hinged to the left and right legs 3 by hinges, and mounted to be openable and closable. Even in the case of such a back plate, similarly to the above-described embodiment, it is prevented from being opened by bolts in a closed state. In this way, by being configured to be openable and closable, it is not necessary to remove the back plate, so that the back plate is easily mounted. Further, one back plate may be mounted so as to be openable and closable so as to be able to stop above the top plate 2 when opened.

In the above embodiment, both the display stand 5 and the CPU stand 6 have the adjusters 5e and 6e.
Although the one with d has been described, a caster may be provided instead of the adjusters 5e and 6d. In particular, casters capable of locking wheels are preferable. With the caster, after the display DSP is mounted, almost no force is required to move the display DSP to a predetermined position, and the burden on the operator can be further reduced.

In the above embodiment, the structural member 10 is mounted only vertically, but instead of the structural member 10 only in the horizontal direction, a structural member having a mouth-shaped frame structure is used. You may. By using a structural member having such a frame structure, the connection structure between the top plate 2 and the legs 3 can be reinforced.

In the display stand 5, CR
In a device that generates heat, such as a T display device, a structure that easily radiates heat may be preferable. In such an example, the side plate 5a of the display stand 5 may be replaced with a plate-like plate of the above-described embodiment, and a frame made of, for example, a steel pipe may be adopted. By using the frame in this way, the ventilation from the side is improved,
The heat radiation efficiency of the display DSP can be improved.

A hood H may be mounted on the window 1. In the case where the glass plate subjected to the anti-reflection treatment is not fitted into the window as in the above-described embodiment, the scene such as the ceiling certification device or the room window may be reflected on the window, making it difficult to see the display screen of the display DSP. . In such a case,
A hood H shaped as shown by the imaginary line in FIG. 2 may be attached to block light coming from above the half-use end side of the top plate 2 and light coming from the side. Such a food H
May be detachably mounted, and may be removed and placed when viewing documents or the like. At the time of use, since the user looks down the display screen of the display DSP from obliquely upward, the opening portion on the front side of the hood H is relatively small, and the height of the hood H is prevented from increasing. can do.

In addition, the configuration of each section is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention.

[0032]

As described above, according to the first aspect of the present invention, since the desk main body and the display device gantry are separate bodies, the display device gantry is different from the original installation position of the desk main body. The display device can be placed at the location. Therefore, since the work is not performed in a narrow space, the burden on the worker can be reduced. Further, since the display device frame is fixed to the desk body by the fastening mechanism, it is possible to prevent the relative position between the display screen of the display device mounted on the display device frame and the window of the top plate from shifting. In particular, for example, even when used by children, even if the feet of the children frequently collide with the display base, the window of the top plate and the display screen of the display mounted on the display base are positioned relative to each other. It is possible to reliably prevent problems such as misalignment and difficulty in viewing,
It is possible to effectively prevent inconvenience in use. Furthermore, if the display device stand is separate from the desk body, even if the type or size of the display device to be used is changed, it can be dealt with simply by replacing the display device stand. Can be much more economical than replacing the entire desk. Further, since the desk main body can be shared, various specifications can be easily manufactured, and the efficiency of inventory management can be easily improved.

According to the invention of claim 2 of the present application, since the display device pedestal can be pulled out, the display device can be mounted on the display device pedestal with the display device pedestal pulled out. The burden on the person can be reduced. In addition, since the display device gantry is fixed at a predetermined position in the space below the top plate by the fastening mechanism, for example, even if the user's lower limb contacts the display device gantry during use, the position of the display device gantry is thereby changed. Deviation can be prevented. As a result, it is possible to reliably prevent a problem that the relative position between the window of the top plate and the display screen of the display device mounted on the display device stand is displaced to make it difficult to see. Further, since the back plate is attached so that it can be opened and closed or detachable, work from the back becomes possible, work for fixing the display device base in a predetermined position, and connecting cables, etc., becomes easy for the operator. The burden can be reduced.

Further, in the case where the rear plate is detachably mounted via the rotation mechanism, the rear plate can be slightly rotated by the rotation mechanism so that the rear surface of the display device pedestal can be seen. Inspection and the wiring status of cables can be easily confirmed.
