Rather, it is to illustrate the support shaft 129 supporting the hinge unit 130 so as to be free to rotate.

However, as one modification of the above-described embodiment, the hinge unit 130 is also configured to be detachably attached to the standing portion 120, and the hinge unit 130 also has a keyboard 140 or a mouse. Similarly to 150, an infrared transmitter is provided, and when the one-touch button 131 provided in the hinge unit 130 is operated, the infrared receiver of the main body 200 shown in FIG. 15 is displayed from the infrared transmitter. It may be configured to transmit toward the 128, to be received by the infrared receiver 128, to be transmitted to the CPU 201, and to perform a process according to the operation of the one-touch button 131.

In addition, although the infrared ray is used in the above-mentioned embodiment to transmit the key operation information of the keyboard 140 to the main-body part 200, another wireless system may be sufficient. In addition, the key operation information may be transmitted by a wired connection of the keyboard 140 and the main body 200 by a cable rather than wireless communication.

19 is a perspective view showing the base 110 of the integrated personal computer 100 and the standing portion 120 with the hinge unit detached.

19, the touch pen 320 is further illustrated. In this way, the touch pen may be provided so that the integrated personal computer may be given an instruction by touching the screen with the touch pen 320 even when the keyboard and the hinge unit are detached.

Although each embodiment is an example of an integrated personal computer, the present invention can be applied not only to an integrated personal computer but also to various electronic devices having a structure folded by other hinges.
