Furthermore, when descending between the lower wall and the intermediate wall of the machine casing 1, a transmission gear is connected to the drive plate 18, the force receiving gear 25, and the pinion 17. A clutch gear 32 that maintains engagement with the driving plate 18 and pinion 17 and separates from the receiving gear 25 when the clutch gear 32 engages and rises is supported vertically and rotatably, and the clutch gear 32 is mounted on a center shaft 33 of the clutch gear 32. 32 and the center shaft 33, a spring 34 is wound around the spring 34 for applying a pressing force to the center shaft 33, and an arcuate protruding driving cam 35 is provided on the lower surface of the driving plate 18, and a third actuating cam 35 is provided on the lower surface of the lower wall of the machine casing 1. The middle of the plate 37 is slidably supported on the shaft, and the tip of the third actuating plate 37 is brought into contact with the lower end of the central shaft 33, and the protruding edge-like driving force is attached to the upper surface of the proximal end of the third actuating plate 37. A protruding driven cam 38 is provided that engages with the cam 35 to push down the base end thereof, and when the protruded driven cam 38 pushes down the base end of the third actuating plate 37, the clutch gear 32 is moved to the raised position. It was designed to be pushed up.

That is, in the above description, the motor M is rotated to rotate the turntable 4 and the record wall 3, and in this way, the needle 1 engaged with the sound groove of the record 3 is rotated.
4 reproduces the sound, and the speaker 9 starts producing sound through the boss 13. When the needle 14 reaches the swing groove at the end of the sound groove, the protruding driving cam 19 pushes down the tip of the second actuating plate 20 via the protruding driven cam 21, pulls down the link 22, and pushes the lever plate 6. 1st through
By sliding the actuating plate 2 upward, the turntable 4 and the record 3 are lifted up, thereby removing the stylus 14 from the sound groove and picking up the pick-up 1.
1 and the needle 14 are instantaneously restored by the spring 1, and when the protruding driving cam 19 comes off from the protruding driven cam 21, the second operating plate 20, the link 22, the lever plate 6,
The first actuating plate 2, the turntable 4, and the record disc 3 return to their original states and automatically repeat the playback performance of the record.
8 is not engaged, the clutch gear 32 maintains the lowered state, and the rotational force of the pinion 17 is transmitted to the vertical shaft 24 via the transmission gear, the clutch gear 32, and the receiving gear 25. 30,
When the pinion 29, the horizontal shaft 27, the rotating case 26, and the driving wheels 28, 28' are in a rotating state, and when the protruding driven cam 38 is engaged with the protruding driving cam 35, the clutch gear 32 receives the force. It separates from the gear 25 and stops the above-mentioned traveling.

As described above, the present invention automatically and continuously repeats the playback performance of a record to perform it smoothly, and it is extremely interesting when incorporated into a toy and used for play.
