Abstract: An image capturing apparatus includes: a first heat-dissipating member to dissipate heat generated by a first heat source; at least one second heat-dissipating member to dissipate heat generated by at least one second heat source; a duct inside which the first heat-dissipating member is disposed, and configured to guide air drawn in from an inlet port toward a first outlet port; and a fan disposed between the first outlet port and the first heat-dissipating member inside the duct and configured to discharge air toward the first outlet port from the inlet port. At least one opening is positioned between the fan and first outlet port, part of the air discharged toward the first outlet port by the fan is pushed out from the opening, and the air pushed out from the opening cools the second heat-dissipating member and is discharged from a second outlet port.

Abstract: In order to provide a pan or tilt head and the like capable of reducing rattling or vibration when a rotation is suddenly changed while reducing the unevenness in rotational speed for smooth rotational drive, there is provided a pan or tilt head including a drive unit which rotates a camera unit in a predetermined direction, first and second gears which rotate around a predetermined rotation axis in the predetermined direction and are coaxial with the predetermined rotation axis, a third gear which meshes with the first and second gears and transmits a driving force from the drive unit, and a biasing unit which biases the second gear in the rotation axis direction, the first gear, the second gear, and the third gear includes helical gears, and the second gear is disposed to be movable in the rotation axis direction with respect to the first gear.

Abstract: An image capturing apparatus is provided with a plurality of image capturing units that capture images in directions that differ from one another, an approximately spherical housing that houses the plurality of image capturing units and that is rotatable around a tilt axis, and a drive unit that drives the housing to be rotated around a tilt axis, and in which at least a portion of the drive unit is disposed inside the housing.
