Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a housing structure of an electronic device such as a control device used with a display device such as a CRT and an input device such as a keyboard.

(Prior Art) Currently, many general-purpose devices called personal computers and workstations have appeared, and these
It mainly consists of a display device such as a CRT, an input device such as a keyboard, and a control device with a built-in microcomputer and storage device, each of which is made into a unit.
In practice, the system is configured by adding a table such as a 0△ table, and the entire system is formed as one device. and,
Conventionally, various configurations of each of these units have been realized, and they are generally classified into the following three types depending on the location where the control device is placed. One is a type in which all units are placed on the table, one is a disk side type in which only the control unit is placed on the floor next to the desk, and the other is an under desk type in which only the control unit is placed on the floor under the table.

When the control device is configured in a vehicle-mounted case, the arrangement of each device is as follows: a keyboard 2 is placed on the turret 1, a control device 3 is placed behind the keyboard 2, and a CRT 4 is placed on top of the control device 3. (Figure 4) Or, use the CRT4 on table 1.
Generally, a keyboard 2 is placed in front of the computer, and a control device 3 is placed next to the keyboard 2. However, if the CRT 4 is placed on the control device 3, the position of the CRT 4 will be high and the C
Since the RT 4 is difficult to see and the depth of the control device 3 is larger than that of the CRT 4, a desk with a larger depth than that on which the keyboard 2 and CRT 4 are mounted is required. In addition, if the keyboard 2, control device 3, and CRT 4 were installed directly on the console 1,
As such, a large area is required.

When the control device @ 3 is constructed of a desk-side freestanding casing, the control device 3 is placed vertically next to the desk 1, as shown in FIG.

However, in this case, since the control device 3 requires space in addition to the desk 1, the exclusive space of the entire system increases.

In addition, when the control device 3 is configured with an under-desk type case placed under the top plate 5 of the table 1, for example, the control device 3
If it is placed horizontally at the bottom of the top plate 5, the position in which the operator can sit will be restricted, such as the operator's knees hitting each other, and the operability of the system will be reduced. It is also possible to place the device 3 vertically at the back of the table 1.
Generally, the palanquin of the monkey 1 is blocked by a shelf 6 or a legrest member that serves to reinforce the car, and in reality, it is difficult to place the control device 3 vertically deep inside the car 1.

After all, in the arrangement of the system in a ring, it is difficult to reduce the space occupied by the entire system unless the control device 3 is made very small.

(Problems to be Solved by the Invention) As described above, in the conventional control device, the workpiece In addition to the space occupied by the display device and input device, which are the minimum requirements for operation, in a system such as a station, a space is required to place the control device, which significantly increases the exclusive space of the system.

The present invention has been made in view of these conventional drawbacks, and allows display devices, input devices, and electronic devices used together with the display device and input device to be placed in the same space as when the display device and input device are placed on a tabletop. It is an object of the present invention to provide a housing structure for electronic equipment in which equipment can be placed without impairing the operability of the system.

[Structure of the Invention] (Means for Solving the Problems) In the present invention, in the case structure of an electronic device used together with a display device and an input device, the case has an inner surface of a pair of opposing surfaces. a top plate mounting part for mounting a top plate on one side of the casing, and a base mounting part for mounting a base for supporting the casing erected on the floor with one side facing up on the other side; The size of the casing is such that it can be used as a table on which the display device and input device are placed when placed on the floor with the top plate and base attached. It has become.

(Function) When using an electronic separate device with the above-mentioned housing structure, by attaching a top plate to one side (top side) of the electronic device and a base to the other side (bottom side), it is possible to use a display device and an input device. It can be used as a table on which to place the electronic equipment, and no space is required for the electronic equipment itself.

Further, in a place where there is sufficient space, it can be freely placed as a standalone device near a table on which a display device and an input device are placed.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to FIGS. 1 to 3.

In the figure, 2 is a keyboard (input device), 4 is a CR1 display device, and 10 is a control device (electronic device) used together with the keyboard 2 and CRT 4.

The size of the casing of the control device 10 is formed to correspond to the leg of a general car on which the keyboard 2 and CRT 4 are placed when placed vertically as shown in FIG. (described later). Further, the upper part of the control device 10 is provided with a screw hole (top plate attachment part) 12 for attaching the top plate 11, and the lower part thereof is provided with a screw hole (base attachment part) 15 for attaching the base 14. . When attaching the top plate 11 to the upper surface (-side surface) 16 of the control device 10, attach the metal fittings 17 and 18 to the screw holes 12 using ports 19.
Then, to attach the top plate 11, screw it onto the metal fittings 17 and 18. Also, the base 14 has the port 20 screwed into the screw hole 15.
The bottom surface (other surface) of the control device 10 by screwing the
It is attached to 21.

A skewer is formed by attaching the top plate 11 and base 14 to the control device @10, and the keyboard 2 and CRT 4 can be placed on the top plate 11 as shown in FIGS. 21 and 3. In this case, since the car is supported by the base 14, there is no risk of it falling over. As shown in FIG. 3, casters 23 are provided on the bottom surface 21 of the control device 10, so that the control device 10 alone or on a stool using the control device 10 as legs can be freely moved. Furthermore, an adjuster 24 is provided on the bottom surface of the base 14, making it easy to adjust dimensions when forming a car.

Since the control device 10 is composed of the above-mentioned casing,
If you want to install a system such as a workstation in a small space, it will become part of the desk and the keyboard 2 and C
It becomes possible to arrange a system having a large-sized control device 10 in the same space as a table on which only the RT4 is placed, and the operability of the system is not impaired. That is, the exclusive space of the entire system is determined by the size of the vehicle, which is determined by the arrangement of the keyboard 2 and CRT 4, which are essential for operation by the operator 26.

If the system can be installed in a relatively large space, place the keyboard 2 and CRT 4 on a commercially available table.
The control device 10 can be arranged as a single unit, such as a desk side type.

Next, the external dimensions of the casing of the control device 10 will be explained.

First, the width W of the control device 10 is equal to the width W of the top plate 11, as shown in FIG. (approximately 800 m
(below). Generally, dimension a is 500
Since it is about mtn, it is not restricted by this,
The latter about 800. It is determined by the above dimensions, and as a result, the width dimension W of the control device 10 is 700 m, rn ~8
00 rrrtn.

Next, the depth dimension shown in FIG. 3 is the depth dimension d of the top plate 11.
Dimension m to ensure space for the legs of the operator 26
Determined by the dimension after subtracting. The depth dimension d of the top plate 11 is
It is related to the sum of the depth dimension C of the CRT 4 and the depth dimension C of the keyboard 2, and the operator 2
It is determined by the appropriate value of the visual distance l of No. 6. The CRT 4 shown by the dashed line in FIG. 3 is shown in a state where the CRT 4 is tilted so that the screen is perpendicular to the line of sight of the operator 26.

First, regarding the sum of dimensions C and b, assuming that the CRT2 has a 14-inch or 1-inch screen, which is the most commonly used type, the dimension C is about 350s to 400#, and the area in front of the keyboard 2 Considering the hand rest space and the gap between the keyboard 2 and the CRT 4, the depth dimension d of the top plate 11 is 750 rrvn or more. On the other hand, viewing distance 1 requires approximately 500 ms, so the CRT
Considering the depth dimension C of 4, d is 750 to 80
It becomes 0 m. Therefore, the dimension d is a satisfactory value for 750 m or less calculated from the sum of the dimensions C and b. Next, since the dimension m for securing the leg space of the operator 26 is generally 400 m or less, the depth dimension of the control device 10 is consequently 350 m or less from (d-m). However, considering strength issues and stability when placed as a freestanding type (vertical type), 30
0 to 350# is considered appropriate.

The height H of the control I device 10 from the floor is the same as the height h of the lower surface of the top plate 11, but h2 requires a space above the knees of the operator 26, which is 620 mm.
m or less is required. In addition, the height hl to the top surface of the top plate 11 is 670 t based on the operability of the keyboard 2.
rm ~ 700 m is considered appropriate, and considering the thickness t of the top plate 11, the dimension h2 is 630 rrvn ~ 670 m.
M, therefore, the height dimension H is set as 630 s to 670 m. Roughly speaking, the gap size S between the bottom surface 21 of the control device 10 and the floor surface is required to be 100 rrvn or more to ensure space for the toes of the operator 26 when he or she puts his or her legs forward. . however,
This dimension S varies depending on the size of the dimension m mentioned above. In this example, it is set to approximately 1008 in consideration of the stability of the control device 10 as a self-supporting casing.

As mentioned above, the external dimensions of the control device 10 are as follows:
This is related to the external dimensions of the CRT 4, and an appropriate value is set mainly depending on various ergonomic dimensional conditions when the operator 26 is in a sitting position. In addition, the external dimensions of the casing of the control device 10 in this example are summarized as 700 rtvn
~800 mm (W) X300 mm-350rr
vn(D)X630mm-670mtrt(H
), (5=100 m>. This dimension is large enough to accommodate the various electronic components that make up the control device @10.

[Effects of the Invention] As explained above, according to the face structure of the electronic device of the present invention, one car can be easily built by attaching a top plate to the top of the electronic device such as a control device and a base to the bottom. Can be formed. Therefore, in a system whose basic configuration is a display device, input device, control device, etc., the entire system can be formed simply by placing the display device and input device on a skewer where the control device, etc. is used as a leg. Since the system does not require space for arranging a control device, etc., the space occupied by the system can be kept to a minimum. On the other hand, it is also possible to use a control device or the like as a single unit, place a display device and an input device on a commercially available vehicle, and arrange the control device or the like near the vehicle.

These days, systems called workstations are beginning to be used for multi-purpose purposes, and by attaching a top plate and base to a control device, etc., the size of which corresponds to the display device or input device that changes depending on the purpose. A dedicated system can always be placed in a minimum space, and the effects of the present invention can be said to be very large.
