Publication number: 20070146311Abstract: A roller apparatus for a computer input device, such as a mouse, that has a sturdier support than prior art supports. A scrolling wheel carriage is supported by a PCB for greater stability. An open hook support for the hinge of a wheel carriage angles outward below a retaining point for the hinge. This combines with the hinge being hollowed out, so that upward forces due to variations in PCB thickness cause the hinge to compress while retained by the hook support. The design also provides long side arms for activating microswitches for lateral scrolling, and stoppers for preventing forward and backward slippage.Type: ApplicationFiled: December 22, 2005Publication date: June 28, 2007Applicant: Logitech Europe S.A.Inventors: Feng-Hao Lin, Chi-ming Wang, Tzu-Ching Chu, Tsung Hsin Hsieh
