<p>PROBLEM TO BE SOLVED: To effectively utilize the upper surface of a computer main body by turning the structure of the computer main body to the structure capable of incorporating an input device and a display device for saving power and saving space in a thin shape and to reinforce a security function by attaching a KEY or the like. SOLUTION: The input device 11 and the display device 21 for saving the power and saving the space in the thin shape are incorporated in the upper part of the computer main body 31. Then, a manager opens the KEY 41 and opens the normally closed display device 21 at the time of operating the computer main body 31. The input device 11 is operated by opening the display device 21. Thus, the upper surface of the computer main body 31 other than the space required for the input device 11 and the display device 21 incorporated in the computer main body 31 is effectively utilized. Thus, since only the manager can open and close the KEY and only a specified small-sized terminal equipment can control the computer main body 31, the security function is reinforced.</p> |
