<p>PURPOSE:To avoid the deterioration in performance or the breakdown of a recording/reproducing part by supporting this part so that it can be pulled out to plural positions on the outside of an outer housing and switching off a power supply after shifting the recording/reproducing part to a pull-in position within the housing. CONSTITUTION:A gear shift 18 projected over a mechanical chassis 4 provided at a recording/reproducing part containing the mechanisms necessary for recording and reproduction is rotated with reverse revolution of a motor 50. Thus a chassis shift gear 19 fixed to the shaft 18 engages a rack 17 and moves forward. Then the chassis 4 is pulled out through the opening of an outer housing 2 with guidance of a guide rolls 8 and 8' fixed at the side of the housing 2 as well as guide rolls 7 and 7' provided to the chassis 4. Thus the chassis 4 is shifted up to a half pull-out position or the pull-out position. When a switch is operated to cut off the power supply, the motor 50 has forward revolutions. Thus the chassis 4 is moved back. Then the power supply is cut off when the chassis 4 reaches the pull-in position.</p> |
