<p>PROBLEM TO BE SOLVED: To make a mechanism small and light in weight by making the other component have the role of a lid opener in common. SOLUTION: The cassette lid opening-closing mechanism is constituted in such a way, approximately a central part of a fixed upper drum 7 is also used as a lid opener of a tape cassette 10 when mounting the tape cassette 10 in a magnetic record reproducing apparatus. Thus the VTR mechanism can be made small and light in weight by using otherwise-purpose components also for displaying the role of a lid opener.</p> |
