<p>PURPOSE:To simplify the input of data via a mouse by securing such a constitution where a cursor enclosure serves as a cursor key when it is attached to a keyboard main body and then serves as a mouse when the enclosure is detached from the keyboard main body respectively. CONSTITUTION:A cursor enclosure 16 is housed attachably/detachably to/from the housing part 15 of a keyboard main body 11 of a personal computer. The enclosure 16 is electrically connected to the main body 11 and functions as a cursor key. At the same time, the enclosure 16 is constituted with a mouse mechanism such as a mouse ball and can work as a mouse via the optical communication carried out between a light emitting window 21 and a light receiving window 22 formed on the side face of the body 11. Thus the enclosure 16 serves as a cursor key when it is attached to the body 11 and then serves as a mouse when it is detached from the body 11 respectively. As a result, the input of data is always easily carried out via a mouse.</p> |
