Abstract
An x- and y-axis translating apparatus independently translates the motion of a primary shaft in the x- and y-axis directions simultaneously to transducers which generate electrical signals representative of the motion of the primary shaft in the x- and y-axis directions. The apparatus may include button-activated switches for convenient activation with the thumb or forefinger, or other fingers.
Claims6
An apparatus comprising:
- a primary shaft including distal and proximal portions, said proximal portion mounted on a rotational shaft to translate motion of the distal portion of the primary shaft in the x-axis direction to the rotational shaft, the primary shaft being coupled to a longitudinal shaft, and the longitudinal shaft having a camming device to translate motion of the primary shaft in the y-axis direction to the longitudinal shaft;
- the rotational shaft being mounted to rotate freely inside a housing and to translate motion of the primary shaft in the x-axis direction to an x-axis transducer;
- pin means for mounting said primary shaft on said rotational shaft, said pin means permitting said primary shaft to be rotated about an axis perpendicular to both said primary and rotational shafts;
- the longitudinal shaft being positioned inside of and coextensive with the rotational shaft to rotate with the rotational shaft and to move longitudinally within the rotational shaft to translate motion of the primary shaft in the y-axis direction to a y-axis transducer;
- and
- a peg attached to the longitudinal shaft that moves within a first slot of the primary shaft to translate motion of the primary shaft in the y-axis direction to the longitudinal shaft.
