Japanese Patent JP2554999
Kind Code:
B2
Abstract:
A mouse (X-Y position controller) having axially-inclined transducer assemblies-preferably almost perpendicular to the surface on which the mouse is operated-for a compact, greatly simplified structure. The drive wheel of such an assembly can then be small relative to the transducer disk of that assembly, with considerably reduced precision requirements for location of indicia on the disk. Moreover, by use of a pair of spaced ring magnets urging the drive wheel toward the operational surface for the mouse, significant contact force against the operating surface is provided while eliminating substantially all of the friction attendant upon use of even a so-called antifriction thrust bearing. Due to the magnitude of the available contact force, the drive wheel can be of a hard and durable material rather than an elastomer and still provide improved tractional characteristics even on such a difficult operating surface as, for example, oiled teflon. Lastly, the arrangement precludes possible contamination of interacting moving components, partly because there are no interacting moving members but mostly because nothing that touches the potentially dirty operating surface ever enters the mouse assembly.
