Line tracing apparatus |
| abstract |
Means for providing the X and Y coordinates of selected points on a line as the line is traced by a projected graticule controlled by a manually movable index; a movable member carrying both an optical graticule projector and a source of radiation is located below a transparent table top and is moved by servo means to follow movement of the index, which index carries radiation sensing means. The servo means operate X and Y encoders, and the operator by actuation a ''''read-out'''' switch selects those points for which the X and Y coordinates are to be provided as outputs. |
