Abstract
A 'mouse'-type position indicating control apparatus has a two-part housing comprising an apertured base and a cover which contains a ball, a portion of which projects through the aperture in the base to support and transport the housing along a support surface. A one-piece molded mounting block rests on the base for holding the ball in position over the aperture while accommodating universal rotation thereof. Code wheel shafts have the opposite ends thereof journaled in bearing grooves in the support block for frictional engagement with the ball for indicating orthogonal components of rotation. Photoelectric transducer elements are mounted on the mounting block. A cap plate covers the mounting block and retains the shafts and photoelectric elements in place. Retaining members on the cover engage the plate for clamping the mounting block against the base. The apparatus is assembled without the use of fasteners or tools except for securing the base to the cover.
