COOLING STRUCTURE OF CAMERA REVOLVING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a cooling structure of a camera revolving device that reduces temperature rise in a housing by churning heat therein and thus improving cooling efficiency by air convection as well as efficiency in heat transfer to the outside of the housing. SOLUTION: A fan 23 blows wind toward a pan motor 21 so that the wind A blown from the fan 23 flows to a power supply 34 from the pan motor 21 through a lower portion of the housing 10 on a back surface side of the housing 10. A fan 33 blows the wind to a power supply 35 so that the wind B blown from the fan 33 flows to an upper portion of the housing 10 from the power supply 35 through the lower portion of the housing 10 on a front surface side of the housing 10. Two types of convection formed by the wind blown by the fan 23 and that by the fan 33 churn the heat in the housing 10 for cooling a tilt motor 31, thereby achieving cooling.
