ABSTRACT:
A motor driven panoramic mounting for cameras which provides an automatic pan range and the ability to pan over 360 degrees. Mechanical actuators on a fixed base act upon a turnstile on a shaft on the rotating table, with the turnstile shaft also rotating two cams that actuate three limit switches. One cam acts upon a single limit switch which determines the automatic range and reverses the table motion at the ends of the automatic range. The other cam acts on two end limit switches which stop the motion. The action of the turnstile and switches brings the table back to the preset automatic range regardless of where it is directed when it placed back in the automatic mode.
