Mouse having buttons which can be operated both vertically and horizontally

Abstract

A mouse includes: an upper case, a lower case, and a rotary member housed in the lower case. Operating levers are provided at a side portion of the upper case and each has a push member integrally formed at lower surface the operating lever such that at the bottom side thereof a first contact portion and a second contact portion are formed laterally to have a stepwise shape and movable in the vertical and horizontal directions. The lower case has an aperture formed in a central portion thereof and a circumference wall in which an elongated guide hole is formed. The rotary member has a ring shape plate rotatably supported around the aperture of the lower case and provided with a mouse movement detector. A pushbutton switch is mounted in a bottom portion of the lower case. The operating portion of the pushbutton switch is operated by the first and second contact portions of the push member. Also, a lever is provided extending from periphery of the rotary member and having at one end thereof an operating knob being inserted in the guide hole of the circumferential wall to rotate the rotary member along the guide hole. Further, a rotary member positioning element prevents rotation of the rotary member within the rotating range in the assembled state. This invention permits any user to readily change the mouse button compressing fingers from the index finger to the thumb or from the middle finger to the ring or little finger.
