<P>PROBLEM TO BE SOLVED: To provide a technology for realizing humidity control inside an electronic apparatus and suppressing migration of a circuit board. <P>SOLUTION: When a liquid crystal television 10 is turned on, a ventilation opening/closing lid 50 is shifted to a predetermined position so that an external ventilation opening 47 of a bottom surface 46 matches with a bottom surface lid ventilation opening 57, which makes a drying system housing part 49 communicate with the outside. The heat of a lamp module 22 is supplied to a desiccant 70 via a heat sink 60, so that the water content being absorbed in the desiccant 70 is evaporated and released to the outside. When the liquid crystal television 10 is turned off, an internal ventilation opening 42 of a case partition wall 41 matches with an upper surface lid ventilation part 52, so that a circuit housing part 48 communicates with the drying system housing part 49. The water content contained in the circuit housing part 48 is absorbed into the desiccant 70 through a communication opening formed from the internal ventilation opening 42 and the upper surface lid ventilation opening 52. <P>COPYRIGHT: (C)2013,JPO&INPIT |
