Abstract
In a panhead device (1) which supports an image sensing apparatus (100) on a panhead (2) and pivots the image sensing apparatus (100) in the pan or tilt direction, a pan pivot shaft (43) stands upright on a base (49) of the device, and a tilt pivot shaft (25) is horizontally disposed above that shaft. The shaft (25) is disposed to be offset in front of the shaft (43). Principal constituting members of a tilting mechanism are disposed behind the shaft (25).
Claims20
A camera device which has an image sensing device supported on a panhead pivoting the image sensing device in a pan or tilt direction, comprising:
- a tilt mechanism tilting said panhead about a tilt pivot shaft;
- a pan mechanism panning said tilt mechanism about a pan pivot shaft;
- and
- a tilt driving unit which includes a motor and drives said tilt mechanism by the motor,
- wherein the motor included in said tilt driving unit is disposed behind said tilt mechanism, and
- pan pivot shaft stands upright on a base of said camera device, and said tilt pivot shaft is horizontally disposed above and to be offset in front of said pan pivot shaft in a back-and-forth direction of said camera device, thereby said tilt mechanism is disposed above and to be offset in front of said pan mechanism in the back-and-forth direction.
A camera device which has an image sensing device supported on a panhead pivoting the image sensing device in a pan or tilt direction, comprising:
- driving force transmission systems for respectively panning and tilting said panhead,
- wherein each of said driving force transmission systems includes power transmission means having a worm and worm wheel, and
- a leaf spring that contacts the end portion of said worm and biases said worm in both a thrust direction of said worm and a radial direction of said worm wheel.
