Claims

[Scope of utility model registration request]

(1) A rotating arm that reciprocates between the inner collet chuck of the cassette case inserted into the cassette case mounting section and the turntable, and a rotating arm that is attached to the tip of the rotating arm and that is fitted into the inner collet chuck. Grasp the compact disc that is on the turntable and set it in the performance position on the turntable, and then press the turntable. a chuck member that grips the upper compact disc again and frictionally fits it into the inner collet chuck; and a chuck member that reciprocates the swing arm between the inner collet chuck and the turntable, and A compact disc playback device comprising an operation control means for controlling delivery of the compact disc between the chuck and delivery of the compact disc between the chuck member and the turntable, the compact disc playback device comprising: The control means is provided between a drive gear, a driven gear meshing with the drive gear and coaxially disposed with respect to the rotation axis of the swing arm, and the drive gear and the swing arm. a crank mechanism that reciprocates the swing arm in a fan shape about its rotation axis; first and second stoppers that stop the swing arm on the inner collet chuck and the turntable, respectively; A compact disc playback device comprising cam means for raising and lowering the tip of the arm while the arm is stopped by the stopper.

(2) In the utility model registration claim (1), the crank mechanism includes a slider having a crankcase mounted on the drive gear and a crank pin slidably provided in the crankcase; A compact disc playback device comprising: a long hole formed along the longitudinal direction of the swing arm so as to slidably receive a crank pin.

(3) The compact disc playback device according to claim (1), wherein the cam means comprises a plurality of cams formed on the driven gear.

(4) In the utility model registration claim (3), the cam means includes first and third cams that act on the swing arm on a line connecting the inner collet chuck and the rotation axis of the swing arm; A compact disc playback device comprising: a second cam that acts on the swing arm on a line connecting the turntable and the rotation axis of the swing arm.

(5) In the utility model registration claim (4), the first and third cams are separated by 180 degrees, and
