Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desktop computer, and more particularly, to a desktop computer having a panel display device such as a liquid crystal display device as a display device.

[0002]

2. Description of the Related Art A liquid crystal display device, which is a kind of panel display device, is thinner and lighter than a CRT display device. However, the liquid crystal display device mounted on these portable computers has a relatively small screen.

[0003] With the recent progress in manufacturing technology, liquid crystal display devices having a relatively large screen have begun to spread, and some desktop computers have begun to adopt such devices. Like the CRT display device, the liquid crystal display device is separated from the device main body, and the liquid crystal display device is commercialized as a single unit.

As described above, when the liquid crystal display device is used separately from the device main body, there is an advantage that the liquid crystal display device and the device main body can be installed at separate places, but on the other hand, a desktop computer system including the display device is provided. Overall, there is a technical problem of poor space efficiency.

For this reason, for example, Japanese Patent Application Laid-Open No. 10-222
Japanese Patent Publication No. 244 discloses a desktop computer in which the entirety of a desktop computer system including a display device is made compact and space efficiency is improved by making full use of the characteristics of a liquid crystal display device that is thin and lightweight. Have been.

[0006]

SUMMARY OF THE INVENTION CD-RO
Regarding the arrangement of the secondary storage devices such as the M drive and the floppy disk drive, in the above-mentioned prior art device, since the floppy disk drive and the CD-ROM drive are arranged below the liquid crystal display device in the order, There was a technical problem that the position of the display device in the height direction was increased.

That is, in the case of a floppy disk drive, it is necessary to provide a substantially semicircular operation concave portion (release groove) for completely pushing the floppy disk as a medium into the apparatus by manual operation on the outer surface of the main body. In the conventional arrangement order described above, the vertical space between the floppy disk drive and the CD-ROM drive is increased by the space for forming the substantially semicircular concave portion. On the other hand, since it is necessary to mount a mechanism such as tilt on the lower stand, the floppy disk drive and the CD-RO
The increase in the interval between the M drives has to be absorbed by moving the liquid crystal display device to the upper side, so that the position of the liquid crystal display device in the height direction becomes higher.

When operating a desktop computer, an operation of alternately visually recognizing the front liquid crystal display device and the keyboard on the near side occurs. For beginners who are not accustomed to operating the keyboard, the viewpoint between the liquid crystal display device and the keyboard is increased. Movement frequency increases. In addition, when the desktop computer is installed on a desk, when the operator switches from the posture for general office work on the desk to the computer operation, a change in posture for visually recognizing the liquid crystal display device occurs. Therefore, even if the increase in the height of the liquid crystal display device is slight,
The change in the working posture of the operator and the movement distance of the viewpoint increase, which greatly affects the overall operability.

[0009] Further, the increase in the height of the apparatus also results in an increase in installation space and a decrease in logistics such as movement, distribution, and packing of products.

On the other hand, in order to reduce the size of the device in the depth direction, it is conceivable to arrange a liquid crystal display device, a main chassis, and a logic package substrate such as a motherboard in this order from the front side. There was no disclosure of a power supply cable or a signal cable connection route between the substrate and the liquid crystal display device, or a fixing technique.

When a connector for connecting a peripheral device such as a printer is arranged at a high position on the main body of a desktop computer, a cable connected to the connector is connected to an operator who watches the liquid crystal display device. In the field of vision, which is annoying and also causes a decrease in operability.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a desktop capable of improving the operability by setting the position in the height direction of a panel-shaped display device to be low, thereby reducing the change in the working posture of the operator and the amount of movement of the line of sight. To provide a type computer.

Another object of the present invention is to provide a desktop computer capable of reducing the installation space by reducing the height dimension and improving the physical distribution such as movement, distribution, and packing.

Another object of the present invention is to provide a desktop capable of preventing generation of unusual noise due to movement or vibration of a cable connected to a panel-shaped display device and reducing a load applied to a connector connecting the cable. To provide a type computer.

Another object of the present invention is to provide a desktop computer capable of reliably grounding a shield coating of a cable connected to a panel display device.

Another object of the present invention is to provide a desktop computer capable of preventing the operability and aesthetic appearance from being deteriorated due to the connection cable of the peripheral device entering the field of view of the operator.
