Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. §119 from an application for A COMPACT PERSONAL COMPUTER WITH LCD MONITOR earlier filed in the Korean Industrial Property Office on Jan. 17, 1996, and there duly assigned Ser. No. 0818/1996. 
     BACKGROUND OF THE INVENTION 
     1. Technical Field 
     The present invention relates to a compact personal computer, and more particularly to a personal computer integrating a keyboard, a flat screen video (e.g., a liquid crystal display) monitor, speakers and a microcomputer body into a single unitary structure. 
     1. Background Art 
     Since &#34;ENIAC&#34;, the first generation of computers that was enormous, as large as a 3-story-building with vacuum tubes, modern computer systems have been developed and reduced dramatically in size so as to be suitable to be used on a desk. Desktop personal computers (PC) are designed to remain in a predetermined work space and typically include separate processor, disk drive, monitor and keyboard components. Smaller and highly portable computer systems such as &#34;laptop&#34; or &#34;notebook&#34; computer disclosed, for example, in U.S. Pat. No. 5,175,672 for Housing Apparatus For Portable Computer Systems issued to Conner et al., U.S. Pat. No. 5,243,549 for Portable Computer With Display In Pivotally Mounted Cover issued to Oshiba, U.S. Pat. No. 5,251,102 for Computer And Computer Terminals With Depending, Supporting Ridge issued to Kimble, and U.S. Pat. No. 5,390,075 for Electronic Apparatus With Flexible Cable Interconnect Having Independently Movable Member Supported On Tab Portions issued to English et al., are constructed for compact transportation from location to location for use by the operator and typically include a fully integrated processor, disk drive and keyboard structure in a clam shell case serving as a housing to which a liquid crystal display (LCD) monitor is pivoted for tilt-up use. At least one problem that I have observed with respect to the &#34;clam shell&#34; housing construction is that the distance between the keyboard and the LCD monitor is limited and can not be varied to accommodate individual user preference because the LCD monitor and the keyboard are mechanically connected. 
     Other portable computer systems that fall between the larger desktop computer and the much smaller portable notebook computer are disclosed, for example, in U.S. Pat. No. 4,832,419 for Adjustable Display Panel For Portable Computer issued to Mitchell et al., and U.S. Pat. No. 5,157,585 for Compact AC-Powerable Portable Computer Having A CPU And Expansion Bay In An Upper Housing Pivotally Attached To A Lower Housing, issued to Myers, in which a main housing structure contains both the processing system and the disk drive system. In Mitchell &#39;419, a separate LCD screen housing structure is pivotally connected to the main housing over a front side portion, and a keyboard is removably secured to the main housing over the front side of the LCD screen housing. When in use, the keyboard is unlatched and removed from the front side of the main housing and placed on the desk. The LCD screen housing is then swung upwardly and somewhat forwardly relative to the main housing to a use position in which the LCD screen may be forwardly or rearwardly tilted to accommodate the individual user&#39;s angle preference. When not in use, the LCD screen housing is tilted back to an upright position and then swung downwardly and inwardly back to its storage position against the front side of the main housing. The keyboard is then re-latched to the main housing, over the front side of the LCD screen housing in order to return the portable computer to its storage and transport orientation. In Myers &#39;585, on the other hand, both the processing system including the disk drive system and the LCD screen are incorporated into a single housing structure having a base containing a disk drive system and an upper housing supporting a processing system and a LCD screen in which the upper housing is permitted to pivot relative to the base to accommodate the individual user&#39;s angle preference. 
     As computer systems advance with significant processing and storage capabilities including multi-media in which the computer user is now able to obtain full benefits of high speed voice and data processing, a specially designed portable housing structure is desired to accommodate the full use of speakers so as to allow the user to listen to high fidelity music, to watch television and movies while enhancing the portability and transportability of such multi-media personal computers. As described earlier, conventional desktop personal computers require separate monitor, speakers and keyboard that operate in connection with a central processing unit. For this reason, all separate hardware components such as a monitor, speakers and a keyboard must be connected to a microcomputer body, and all of which occupy a significant work area on a desk. Moreover, it is necessary to purchase respectively a video card such as a MPEG board or the like so as to process high speed video signals. Another problem encountered with conventional desktop computers is that it is difficult for computer users to transport desktop computers from one location to another. The computer users must disconnect all separate hardware components from the computer for transportation and then reconnect all the separate hardware components upon arrival, all of which may cause systematic errors or interruption of the individual component when re-connected improperly. Conventional notebook personal computers, on the other hand, are physically restricted to accommodate built-in speakers for multi-media use. Accordingly, a specially designed portable housing structure for personal computers is required to best accommodate recent advances in computer technology.
