Claims
- 1. A tool for applying retro-reflective dots from a sheet of retro-reflective material to a display screen to identify defined calibration points for spacially aligning images, said tool comprising:
- a support platen for said sheet of retro-reflective material;
- a punch mechanism for punching dots of material from said sheet of retro-reflective material;
- a carrier for said punch mechanism for variously supporting said punch mechanism with respect to said support platen for taking dots from said sheet of retro-reflective material;
- a transport mechanism for transporting said punch mechanism to a position remote from said support platen and for activating said punch-mechanism to deposit a dot of material from said sheet of retro-reflective material on said screen at a calibration point; and
- a frame affixed to support said support platen, said punch mechanism, said carrier and said transport mechanism.
- 2. A tool according to claim 1 wherein said punch mechanism incorporates a solenoid for actuation to punch a dot.
- 3. A tool according to claim 1 wherein said carrier comprises a rotary structure for rotating said support platen with reference to said punch mechanism.
- 4. A tool according to claim 1 wherein said transport mechanism includes a rotary structure for revolving said punch mechanism from a loading position to a deposition position.
- 5. A tool according to claim 1 further including a target structure for alignment of said tool with reference to a laser beam.
- 6. A tool according to claim 1 further including an elongate handle affixed to said frame.
