BRIEF SUMMARY
SUMMARY OF THE INVENTION
It is well known to provide an automatic record changing apparatus which comprises means for playing a record, including a rotating magazine presenting slots designed to receive records, said slots being shaped so that the plane of each record is appreciably parallel to the rotation axis of the magazine, the assembly of the records occupying a space of general toric form, means for controlling the angular displacements of the magazine to voluntarily bring each of the records to a selection position, a control mechanism allowing extracting of the record occupying the selection position in order to bring it to a playing position by said playing means and then to replace it in its slot.
In such well known apparatus, the rotating magazine is driven by a particular device in order to bring it to the position where the chosen record moves into a selection position. The control mechanism is formed by another independent device which must cooperate with the record in the selection position in order to bring it to playing position.
Such well known apparatus are heavy and cumbersome and comprise a large number of mechanical parts. This results in the necessity of effecting numerous delicate adjustments which render the apparatus expensive and expose it to numerous risks of faulty operation.
The present invention has for its object to remedy these disadvantages and provide an automatic record changing apparatus which is simple, light and less cumbersome while offering a large loading capacity capable of containing a large number of records. In addition, the apparatus is sturdy and requires practically no adjustment.
The automatic record changing apparatus according to the invention is characterized in that it comprises a base carrying a motor providing the drive means for the rotating magazine, a pivot around which the magazine turns, the free end of said pivot carrying the control mechanism.
If, in addition to the preceding arrangement, rotation the axis of the magazine is inclined so that it makes a 45.degree. angle with a horizontal plane, there is obtained a minimum of space occupied by the device as far as depth is concerned.
The attached drawings illustrate, schematically and by way of example, a preferred form of execution of the record changing which is the object of the present invention in which:
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 is a lateral schematic view showing the general arrangement of the apparatus.
FIG. 2 shows the front of the space occupied by the records carried by the magazine.
FIG. 3 is a partial section along the axis of rotation of the magazine and showing the record changing mechanism.
FIG. 4 shows the front of the mechanism for rotatably driving the record for the playing thereof.
FIGS. 5 and 6 are plan views of a part of the pick-up arm control mechanism .
DETAILED DESCRIPTION
In reference to FIGS. 1 and 2, the apparatus comprises a rotating magazine 3 mounted on a tubular pivot 2 connected with a base 1 and inclined at 45.degree. in comparison with a horizontal plane. The magazine 3 includes spaces each forming a slot for a record 5. The assembly of the records carried by the magazine 3 occupies a space of general toric form whose exterior diameter is designated by C in reference to FIG. 2.
The pivot 2 further carries a case 4 shielding a mechanism allowing the extraction of a record 5 from its slot in order to bring it to its playing position 5'. In this playing position, the record is driven by a boss 19 and the playing is effected by a play-back head carried by a pick-up arm 20.
As shown in FIG. 1, the 45.degree. inclination of the rotation of the magazine allows obtaining a minimum of space occupied by the apparatus, its depth A and its length B, both being smaller than the exterior diameter C of the toric space occupied by the records 5.
FIG. 3 shows the principal part of the record changing mechanism. The pivot 2 on which the magazine turns is comprised of a tube whose end is connected with the supporting base 1, while its other end carries the
