Abstract: An alignment override control for effecting automatic vertical alignment of a test axis of an ophthalmic instrument (10) with the center of an eye is disclosed. The test axis is associated with optical alignment means of the instrument vertically movable by an elevation motor controlled by a motor drive. A joystick (24) and a pair of directional switches (28a, 28b) are connected to the motor drive for manual positioning of the test axis. When the eye comes within a field of view defined by the optical means, the override control disconnects the switches and automatically signals the elevation motor to effect automatic alignment using signal information originating from the optical means.

Abstract: Se describe un control limitador de alineacion para llevar a cabo alineacion vertical automática de un eje de prueba en un instrumento oftálmico (10) con el centro de un ojo. El eje de prueba se asocia con medios de alineacion opticos del instrumento que se pueden mover verticalmente por un motor de elevacion controlado por un impulsor de motor de elevacion controlado por un impulsor de motor. Una palanca de mando (24) y un par de conmutadores direccionales (28a, 28b) están conectados al impulso de motor para colocacion manual del eje de prueba. Cuando el ojo se coloca dentro de un campo de vision definido por los medios opticos, el control limitador desconecta los limitadores y automáticamente señala al motor de elevacion que lleve a cabo una alineacion automática utilizando informacion de señal originada desde el medio optico.
