<p>PURPOSE:To reduce a dimension in a width direction by separately providing mechanisms to absorb two overstrokes. CONSTITUTION:A cassette loading mechanism is composed so that the overstrokes obtained when a cassette is inserted to a cassette holding part 10 may be absorbed by an intermediate gear 23, and the overstrokes at the loading completion position may be absorbed by an arm driving gear 24 and a driving arm 25. That is, the driving arm 25 and the arm driving gear 24 are rotated in an arrow B direction by the movement of a guide pin 15 along a first guide groove 321 on a loading completion position side, and a synchronizing gear 231 fitting into the arm driving gear 24 is rotated in an arrow C direction. Consequently, a spring 27 is extended, and the overstrokes at the time of the insertion of a cassette 50 is absorbed between the synchronizing gear 231 constituting the intermediate gear 23 and the guide gear 232. Thus, the width dimension can be reduced.</p> |
