Although such an arrangement is not particularly inconvenient for home use where the player is always installed and stationary, it is not particularly convenient for portable devices such as hand portable pull players or players installed in automobiles. In particular, porta-pull devices installed in automobiles typically produce various noises that are transmitted to the scanning assembly carrying the laser and produce unpredictable movement noises that cause wear and possibly damage. Subject to unpredictable acceleration, deceleration, and impact.

Referring to the drawings, FIGS. 1 to 3 show a device for fixing a scanning laser assembly according to an embodiment of the present invention.
1 shows a laser disc player including a laser disc player. The disc player is based on a fixed frame 1°, to which are attached a movable record positioning housing 19, a motor 14, and a drive unit 12 connected to the motor 14 and including 16 rotating discs. As shown in Figure 2, when the device is in the playing or operating position, the disk 16 engages the record 18 as the record 18 rotates at a relatively high speed.

Although the scanning device of the illustrated player is of the balanced arm type, the invention also applies to linear carriage type players. In the described embodiment, the scanning laser support member 20 includes a laser light source 22 and the necessary optical equipment mounted at one end of a lever 24 arranged to rotate around a spindle 26 fixed to the frame 10K. It allows the user to read information on the disc and record information on the disc. The scanning assembly has a permeable magnetic field which interacts with the magnetic field generated by the 1H control circuit (not shown) for controlling the position of the 1st member during operation of the player. The change in magnetic field causes the laser 22 and its associated optics to move over the surface of the rehood from its inner diameter (indicated by dashed lines in FIG. 1). The lever 24 is rotated fully around its axis 26 in order to be able to scan up to the outer diameter (indicated by solid lines). However, when the device is switched to its inactive or loaded position as shown in FIG. The magnetic flux is eliminated and the arm 24 is free from any external force applied to the shaft 26.
Become free to rotate around.
