<p>PURPOSE:To prevent the damage of the mechanism and the cassette, by making it impossible to hold the fast forwarding and rewinding lever when the cassette is not inserted yet and by reelasing the holding of this lever at the eject operation time in the fast forwarding and rewinding state. CONSTITUTION:When tape cassette C is inserted to the holder in frame A, the tip of cassette C turns eject turning lever 6, and magnetic head plate 8 is slid through turning lever 13 and projected shaft 12 by spring 14. Accompanied with this sliding, turning link 25 is turned to allow moving pin 27 into contact with hooks 23 and 24. At the fast forwarding time, when lever 16 is depressed, the outside slope of hook 23 is allowed into contact with projected shaft 12 to move magnetic head plate 8 backward, and hook 23 is detained by moving pin 27. Similarly, at the rewinding time, hook 24 is detained by moving pin 27 by depression of lever 18. At the eject time, magnetic head plate 8 is moved backward by depression of eject lever 2, and tongue piece 15 moves moving pin 27.</p> |
