<p>PURPOSE:To remove the dew of a head drum with lower electric power consumption without requiring a space for installation by blowing heated hot wind through an aperture of a casing in a loaded state to a head drum. CONSTITUTION:The reel shaft of this VTR is inserted into holes 15, 16 of the casing 14 when a cassette is loaded. An operating element 26 is then pressed by the insertion of this reel shaft into the hole 15 and a switch 25 is turned on. The power source currents of batteries 23, 24 are, therefore, supplied to a heater 20 and a motor 22 from the batteries and the wind is sent from the aperture 18 in an arrow direction toward the aperture 17 by a fun 21. The wind is heated by the heater 20 and is blown as the hot wind from the aperture 17 toward the head drum, by which the dew of the head drum is removed. The dew of the head drum is removed in this way with the lower electric power consumption without forming the apparatus to larger sizes.</p> |
