ABSTRACT:
A magnetic recording/reproducing apparatus having an opening and closing door for loading and unloading a magnetic sheet pack, the door being adapted to override a position wherein the door is locked and then to return thereto, upon loading the magnetic sheet pack. The door has a pressure member which, during the overriding movement of the door, presses a center core of the magnetic sheet to forcibly mount the magnetic sheet onto a spindle. The pressure member is spaced from the center core when the door retreats to its locked position, in which the door cannot move in any direction. A switching member is provided so as to control a driving motor for the spindle in cooperation with the action of a mechanical device for locking the door.
