<p>PURPOSE:To diminish a moving amt. of a cassette holder in a horizontal direction at the time of its ejection and to contrive miniaturization of the subject device by making a distance from a turning center of an ejection means to a pushing part larger than a distance from the above center to a position where an engagement pat provided to the holder and an engagement means are brought into contact with each other. CONSTITUTION:At the time of ejecting a cassette, the engagement part 6c is engaged with the engagement means 5 in the opposite direction to the case of inserting the cassette in accordance with the movement in the direction of ejecting the cassette holder 6, and the engagement means and the ejection means 1 are turned in the ejecting direction as they are under their engagement relationship. Then, the pushing part 4 of the ejection means is brought into contact with a tip part of the cassette 7 so that the cassette is pushed out. When the movement is further carried out, the engagement means and the engagement part are released from their engagement and restored to their prescribed positions respectively. When the distance from a turning center hole 1a to the pushing part 4 is denoted as (e), and the distance from the said hole to the engagement position of the engagement means with the engagement part is (f), while the holder moving amt. (h) and the cassette moving amt. (g), if (e) > (f), (g) > (h), that is, the holder moving amt. is magnified and transmitted to the cassette.</p> |
