Claims

[Scope of Claim for Utility Model Registration] A transport holder into which a manually slotted cassette is fitted and moves together with the cassette in a DAT cassette insertion passage; An attached ejection lever, which has a groove concentric with the rotation axis on the free end side, a groove continuous with this groove in the longitudinal direction, and a pin on the lower surface that engages with the lid of the cassette. an ejection lever; and a spring that is stretched between a predetermined location of the ejection lever and a predetermined location of the ceiling plate and biases the ejection lever in the cassette ejection direction when the cassette is inserted within a predetermined distance. A cassette ejecting mechanism for a DAT equipped with a pin having a free end located in the groove on the upper surface of the holder, and a cam portion provided on a predetermined portion of the groove on the rotation axis side, When the moving distance of the ejection lever exceeds a predetermined value, this cam part contacts the pin of the holder in an inclined state, and the distance between the contact point and the rotation axis is greater than the distance between the pin of the ejection lever and the rotation axis. A DAT cassette ejecting mechanism characterized in that the cassette ejecting mechanism is short and further becomes shorter as the holder moves.
