Claims

[Scope of Claim for Utility Model Registration] A drive gear that is constantly rotated by a motor, a notch gear that has a toothed part that meshes with the drive gear and an incisor part that does not mesh with the drive gear, and the notch gear that is rotated by the drive gear. an electromagnetic notch gear lock mechanism that holds the notch gear so that the drive gear idles in the incisor portion of the mechanism; a swing lever for driving an eject mechanism; and a swing lever for driving the eject mechanism, and the unlocked notch gear meshes with the drive gear. a leaf spring fixed at one end to the swing lever so as to rotate it to a position where it can be rotated; an eject spring that provides driving force to the lever; and a notch gear that rotates the swing lever at a position locked by the lock mechanism. A dowel for retracting the swing lever is provided on the notch gear so as to keep it rotating as much as possible against the elasticity of the eject spring, a trigger bar locks the fast forward or rewind lever in the pushed position, and the fast forward or rewind lever It is equipped with a stop lever that controls the rotation range so that the swing lever does not rotate to the eject position when the lever button is pressed, and a fast forward mechanism with a magnetic head in sliding contact when searching the beginning of the cassette tape. Alternatively, in the cassette deck cueing mechanism that runs the tape in a rewound state and temporarily releases the notch gear locking mechanism when an interval between songs is detected, allowing the notch gear to rotate by one rotation. On the notched gear locked by the notched gear lock mechanism, there is a [・
A cassette deck characterized in that a dowel for rotating the trigger lever is provided, and the engagement between the trigger lever and the fast forward or rewind lever is released by a slight rotation angle of the unlocked notched gear. cueing mechanism.
