<p>PURPOSE:To interlock the mounting and ejecting operations of a cassette with the motion of a magnetic head, in a tape recorder where a two-reel tape cassette is inserted in its longish direction and in accordance with the cassette insertion, a reel axis and capstan axis are inserted down into the tape cassette. CONSTITUTION:Head mount board 4 is rotatably supported by driving mechanism mount board 3 and link member 22 and while head mount board 4 is moved forward or backward in the cassette mounting or ejecting direction as driving mechanism mount board 3 moves forward or backward, head mount board 4 is put in arc motion restrained by link member 22 so as to move magnetic head 13 and pinch roller 14 toward or away from cassette C. Here, inserting cassette C depresses pin 17, and consequently mount board 3 is put in arc motion restrained by links 15 and 16 to rise moving in the insertion direction. On the other hand, mount board 4, moving in the insertion direction as pin 18 operates, turns on pin 18. At the same time, the magnetic head and pinch roller are inserted into the fixed opening part of the cassette.</p> |
