Abstract

PURPOSE: To trace a sound groove at a constant angular velocity, by changing a running speed of a car body in accordance with a turning angle of a cartridge, in a free-running record player for executing a musical performance by making the car body provided with the cartridge run on the sound recording disk.
CONSTITUTION: When a car body 2 is made to run by rotating a driving wheel 8 through a gear mechanism 5 by a motor, a reproducing stylus 26 of a cartridge 20 traces a spiral sound groove of the sound recording disk. As soon as a reproducing signal is received, the cartridge 20 turns in the inside direction of the disk together with an arm 25, making an adjusting axis 23 a supporting point, and a guide wheel 19 also turns in the inside direction. Following this turning, the car body moves in the inside direction, running rotatively on the disk. In this case, the adjusting axis 23 of a motor control volume for adjusting a running speed is also turned through an adaptor plate 21, and the running speed is changed. The reproducing signal can be sounded by a loudspeaker provided on the car body, and can be transmitted to the outside, as well.
