Abstract
An automatic panning device adapted for use with camcorders and similar equipment includes a bi-directional electric motor which is connected to rotate a mounting plate upon which the camcorder is secured. A control circuit controls the direction and speed of rotation of the mounting plate so as to pan the camcorder back and forth throughout a predetermined angular displacement. In a first embodiment, the amount of such angular displacement is controlled by a pair of limit arms which are pivotably secured to the mounting plate. A proximity sensor is provided for sensing panning movement of the limit arms with the mounting plate to a predetermined location. When this occurs, the proximity sensor generates a signal to the control circuit to reverse the direction of rotation. In a second embodiment, the proximity sensor is provided on the mounting plate and is moved relative to a pair of limit targets slidably mounted on a housing for the device. In a third embodiment, the amount of such angular displacement is controlled by an electronic rotational limit circuit connected to the control circuit. In a fourth embodiment, the amount of such angular displacement is controlled by an elect…
