<p>PURPOSE:To eject a cassette surely by operating the holding unit of a cassette transfer means according to the operation of a cassette ejecting means and regulating the operation of the ejecting means by the holding unit until the cassette reaches a prescribed height at an eject time. CONSTITUTION:When an ejecting button is depressed, cam gear 34 is rotated through the decelerating gear interlocked with a motor. BY this rotation, roller 39 brought into contact with inclined cam 35 is depressed to cause cassette arm 44, which is put on roller 40 at the right end of arm 38, and the cassette holder to start ascending to the ejecting position. In this time, depression of depressing part 95 of cassette arm 44 is released in contact part 94 of inject arm 76, and force is given in the cassette contact direction by spring 78, however, cam hole 79 of inject arm 76 is controlled to arc-shaped protrusion 74 of cam gear 34, thereby regulating rotation. When cam gear 34 advances rotation and the cassette ascends to the ejectable highest position, arc-shaped protrusion 74 is desconnected, and injecting arm 76 starts rotating while causing the face of cam hole 79 and the end of protrusion 74 to contact with each other, thus starting cassette ejection.</p> |
