Automatically loading mechanism for magnetic recording/reproducing apparatus

An automatic tape pack loading mechanism for a magnetic recording/reproducing apparatus which comprises:

• a slidable frame member for receiving a tape pack therein;
• means for detecting the tape pack when it is loaded in said slidable frame member;
• cam means actuatable by said detecting means;
• guide means for directing the sliding movement of said slidable frame member;
• first resetting spring means;
• a first slide member which is urged by said first resetting spring means toward a first position;
• second resetting spring means;
• a second slide member which is urged by said second resetting spring means toward a second position, said second slide member being movable by said cam means away from said second position when the tape pack is loaded in said slidable frame member;
• first switch means adapted to be selectively closed or opened in response to movement of said second slide member of said second slide member away from or toward said second position, respectively;
• a motor adapted to be controlled by said first switch means;
• first engaging means provided on said first slide member and rotatable upon actuation of said motor;
• second engaging means provided on said second slide member and engageable with said first engaging means upon movement of said second slide member by said cam means away from said second position;
• third resetting spring means;
• first rotatable means urged by said third resetting spring means to a third position, said first rotatable means being engaged with said slidable frame member;
• third engaging means coupled to and driven by said second engaging means and and adapted to selectively engage said first rotatable means for rotating said first rotatable means away from said third position when said motor is actuated;
• and
• holding means controllable by said first switch means for maintaining the engagement between said first and said second engaging means;
• said first rotatable means being adapted to rotate until the tape pack received in said slidable frame member reaches a recording/reproducing position within said magnetic recording/reproducing apparatus.
