Embodiment Construction

[0025] FIG. 3 shows a scroll wheel 60 and a scroll wheel bracket 62 installed in a mouse bottom housing 64 according to an embodiment of the present invention. A ratchet spring 66 engages the detent inside the roller 60 . A front hinge 68 is integrally formed with the roller bracket 62 which consists of a single piece of plastic. Hinge 68 has a hollow center 70 . The hinge is supported by an open hook support 72 as shown in more detail in FIG. 7 . As in the prior art, the scroll wheel can be rotated to provide a scrolling or other Z-direction input signal. The scroll wheel can also be tilted sideways to provide horizontal scrolling or another X-direction input.

[0026] The side view shown in FIG. 4 shows the roller bracket 62 supported by a printed circuit board (PCB) 88 . By having the scroll wheel bracket rest against the PCB, the PCB can help absorb shock when the mouse is dropped by distributing the force across the length and width of the PCB. The PCB also constrain...

Abstract

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.
