PURPOSE: To enable a soft loading and soft ejection by driving a cam gear with the rotation of a motor by interlocking a holding lever, driving lever and SW lever and allowing the cam gear rotated even by an ejection lever.
CONSTITUTION: When the cassette 25 placed on a cassette holder 16 is inserted, the SW lever 8 moved with the cassette 25 drives a motor via a switch and the cam gear 13 equipped with a tooth missing part 13a is rotated at the specific angle by the worm gear 12 which is engaged therewith to perform a loading, so the noise at the loading tie of the cassette 25 is reduced. When an ejection lever 23 is pressed, the tooth wheel part of the cam gear 13 rotated via an actuating arm 14 performs the ejection with its rotation by a motor by engaging with a worm gear 12, so the operation force for the ejection is reduced. A soft loading and soft ejection can be performed by one motor and one cam gear 13, and the cost is reduced as well.
