<p><P>PROBLEM TO BE SOLVED: To create a magnetic recording reproducing device with a dew condensation detection function, in a configuration used for various kinds of electric devices, having excellent characteristics which can raise detection sensitivity for the dew condensation with reduced size on condition, for example, that a lid for a cassette is opened even in movement between environment where humidity is so high as 90% or more and less temperature difference with the temperature difference 5 degrees or less. <P>SOLUTION: An open and close detection means 7 for a lid of a cassette detects that the lid of the cassette is open and inputs it into a comparison circuit 33. By lowering a decision threshold by a reference voltage generating circuit 32, a magnetic recording reproducing device with the dew condensation detection function, which can detect easily the dew condensation by the input from a dew condensation sensor 1 in a condition where the dew condensation actually tends to generate inside, is obtained. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
