Magnetic recording and reproduction apparatus

A magnetic recording and reproduction apparatus for recording information to, and/or reproducing information from, a magnetic tape accommodated in a cassette, the magnetic recording and reproduction apparatus comprising:

• a main chassis on which a rotatable head cylinder for recording information to, and/or reproducing information from, the magnetic tape is mounted;
• a sub chassis movable relative to the main chassis;
• a cassette holder for holding the cassette and mounting the cassette on the sub chassis;
• a cassette holder elevating section for moving the cassette holder up and down with respect to the sub chassis;
• a holder engaging section provided on the main chassis;
• and
• a main chassis engaging section provided on the cassette holder;
• and
• a guide section for including a projection guide section provided on the main chassis and a guide groove provided in the sub chassis, the guide section guiding the sub chassis relative to the main chassis by the projection guide section and the guide groove being engaged with each other;
• wherein:
• the sub chassis is movable relative to the main chassis from a cassette mountable position at which the cassette is mountable on the sub chassis to a tape pull-out position at which the magnetic tape has been pulled out from the cassette and wound around the rotatable head cylinder;
• the holder engaging section and the main chassis engaging section are engaged with each other at the tape pull-out position, and
• the holder engaging section and the main chassis engaging section are engaged with each other in the state where at least one of the main chassis engaging section and the holder engaging section is inserted through the guide groove.
