ABSTRACT:
An automatically loading and unloading mechanism for a magnetic recording/reproducing apparatus. Tape pack detecting element is provided within an area where a tape pack is to be inserted. A cam member is operable by the tape pack detecting element to actuate a second slide member. The second slide member is provided with a gear meshable with a pinion provided on a first slide member, a worm wheel meshable with a gear portion of a rotating lever pivotally connected to a chassis together with a resetting spring, and an attracting portion for holding the second slide member in the actuated position by an electromagnetic mechanism. The rotating lever has a fork portion engageable with a guide formed on a slidable frame member and leading the guide along a bent slot formed on a guide member. An actuating lever is positioned so that it may be operated by the guide led along the bent slot. A motor for driving the pinion is incorporated in a power source circuit in relation with the electromagnetic mechanism. A power switch operated by the second slide member and an ejecting switch operated by an ejection operating portion are connected in the power source circuit.
