<P>PROBLEM TO BE SOLVED: To provide a dome type camera for preventing dew condensation on an inner face of a dome cover in accordance with a change in a photographing direction of a lens portion with a simple structure. <P>SOLUTION: A dome type camera 1 includes: an almost cylindrical housing having a center hole 12d; a lens portion 21a supported by the housing so that a pan can rotate; a dome cover 11 which is attached to the center hole 12d and covers the lens portion 21a; a fan 26 generating an air flow; and an air guide 15 changing a direction of the air flow which the fan 26 generates. The fan 26 is fixed in the housing so that the air flow flows along an inner wall of the cylindrical housing and annularly circulates with a pan rotation axis of the lens portion 21a as a center. The air guide 15 integrally pan-rotates with the lens portion 21a and changes the direction of the air flow which annularly circulates to a dome cover-side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
