Patent ID: 8279175

Claim:
A slim mouse for mobile appliances using a tactile sensor including multiple force sensors, the slim mouse comprising: a lower polymer film having a first metal layer on an upper surface of the lower polymer film; an upper polymer film having a second metal layer on a lower surface of the upper polymer film; a tactile sensor portion including multiple force sensors, each force sensor including a pair of first resistance patterns formed on the first and second metal layers respectively to face each other at a distance with a spacer disposed between the first and second metal layers; a click-detection force sensor including a pair of second resistance patterns formed on the first and second metal layers respectively, a weight-bumper spacer formed on the upper polymer film, the weight-bumper spacer including a first donut sensor portion and a first click-detection sensor portion, wherein the first donut sensor portion is formed in a ring shape and the first click-detection sensor portion is formed in a center of the ring shape of the first donut sensor portion, wherein the first donut sensor portion comprises a protruding bumper that protrudes toward the force sensor; a pad formed on the weight-bumper spacer, the pad including a second donut sensor portion and a second click-detection sensor portion, which correspond respectively to the first donut sensor portion and the first click-detection sensor portion; and wherein the force sensors are circularly arranged along under the first donut sensor portion and the click-detection force sensor is disposed under the first click-detection sensor portion so that a user can perform a touching or rotating action on the second donut sensor portion using a finger to move a mouse cursor.
