DATA RECORDING DEVICE IN THE FORM OF AN ARRANGEMENT FOR ENTERING POSITION OR MOTION PARAMETERS

摘要

Data recording device for input of position or motion parameters. The invention provides a technical solution which enables an undisturbed uniform suspension of a trackball and allows optimal, unlimited rotation of the trackball around three axes by the human hand. This is achieved by an arrangement containing a trackball (9), optical sensors, at least one measurement magnet (10) and a support unit in the form of a casing (13), in which the trackball (9) is mounted so it can rotate around at least one axis, and its rotational positions are captured by the optical sensors and the measuring magnets, the housing (13) contains three spring body mounts (1), each of these forming a mount for an elastic spring body (3, which is connected with the ball-mounting (14), whereat the ball-mounting (14) contains recesses (6) for the optical sensors and a mount (7) for the measurement magnet (10) and holds the trackball (9) with four bearing points (5).
