Disc recording and/or reproducing apparatus for use in an image pickup device

A dew sensor for detecting moisture in a space enclosing an optical pickup device is disposed in the vicinity of a pickup lens of an optical pickup device and on a partition wall on which a table rotation device is supported. According to the dew sensor a phenomenon in which it becomes impossible to record and/or reproduce an information signal with respect to a disc shaped recording medium when the pickup lens of the optical pickup device becomes dim caused by a dew condensation will be avoided.
