Abstract
A scanning mechanism for tracing an outline and transmitting signals to a control mechanism of, for example, a cutting machine includes a photo-electric cell which is movable in an elliptical orbit by an electro-magnetic drive. The cell is mounted within a housing which mounts optical means for casting an image of the object to be scanned on to the cell.
Claims8
A scanning mechanism comprising:
- a housing;
- a support member carrying a photo-electric cell mounted within said housing and movable to allow said cell to move in an elliptical orbit;
- electro-magnetic means mounted within said housing;
- magnetic means secured to said support and positioned within a moving field producible by said electro-magnetic means, such that on energisation of said electro-magnetic means by a power supply said moving field thereby causes movement of said magnetic means and said cell in said elliptical orbit;
- and
- optical means mounted in a wall of said housing to direct an image of an object located outside said housing onto said cell.
