<p>PURPOSE:To hold a cassette holder stably on a chassis by setting a member which retracts the opposite side of the cassette holder to a locked side and driving the member by a loading motor. CONSTITUTION:When a cassette holder 4 comes to a loading position, a loading motor 16 is rotated to transmit a driving force sequentially to gears 15-11. When the gear 11 is rotated, since one end 9b of a retraction driving lever 9 is engaged with a cam groove of the gear 11, the retraction driving lever 9 is rotated about a rotary fulcrum, moving an inclined U-shaped bent part 9a in a direction 18. In consequence, a retraction member 8 engaged with the bent part 9a at one end 8b is rotated about a fulcrum 8a in a direction 5 thereby pulling a retraction pin 10 fixed to the cassette holder 4. Accordingly, both sides of the cassette holder 4 are held at the loading position by a lock arm and the retraction member 8. It is desired that the retraction member 8 finishes pulling before a magnetic tape is drawn out.</p> |
