Claims

[Scope of utility model registration request]

The cassette holder that holds the cassette half is
A cassette holder is connected to one end of an ejection lever, which is rotatably supported opposite to the front surface of a cassette drive unit having a capstan and a reel stand, and which is rotatably supported. The other end of the eject lever is provided with a pressing part for the drive lever to come into contact with and push the cassette holder in the closing direction. A second spring is provided which pulls the eject gear toward the eject gear. The drive lever is swing-driven by a provided drive pin, and the position of the drive pin is such that when the missing tooth on one side of the eject gear faces the drive gear, the drive lever is oscillated. The eject gear is pressed in the direction in which it is locked by the locking member by the urging force of the second spring, and when the other missing tooth of the eject gear is facing the drive gear, the urging force of the second spring presses the eject gear in the direction in which it is locked. An ejection device for a cassette tape player, in which an eject gear is arranged so that it is pushed in a direction in which it is locked by a locking member.
