<p><P>PROBLEM TO BE SOLVED: To reduce the number of components as far as possible and to surely input operation, in extremely simple structure, even without moving a mouse device itself. <P>SOLUTION: A small ring 21 and a large ring 22 constituted of conductive members concentrically disposed in a horizontal direction and a rotary body 23 constituted of a conductive member of which end portions are slidably engaged with these small ring 21 and big ring 22 so as to slide, are provided within a device casing, and the big ring 22 is divided into a plurality of conductor ring portions 222 by a plurality of insulating ring portions 221 formed at fixed intervals in a circumferential direction. The rotary body 23 is provided so as to be horizontally rotatable along with the small ring 21 and the big ring 22 and, the device casing is inclined from the horizontal state in any arbitrary direction, so that the rotary body slides and rotates, by gravity, on the rings 21 and 22 in the direction of inclination. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
