A record player device comprising:
- a platter member comprising a disc for supporting a record, a hollow platter member, and a base plate portion, said disc having a center spindle;
- a support means for providing support;
- a driving motor;
- and conduit means adapted for providing compressed air from a compressor;
- slanting said base plate portion having a center aperture formed therein;
- said hollow platter member being composed of two concentric cylindrical portions as an upper first cylindrical portion with a greater diameter than the other, and lower second cylindrical portion with a smaller diameter, the first cylindrical portion mounting the disc on an upper face thereof centrally of said disc;
- said second cylindrical portion being extended upwardly from the base plate portion;
- a horizontal annular portion having said two concentric cylindrical portion intermediated therewith;
- said support means comprising a supporting body member housed in said platter member, said support means including an annular flange portion positioned within said first cylindrical portion opposing said disc and said slanting annular portion, and defining an upper horizontal laminated annular air-channel and a lower horizontal laminated annular air-channel, a circular base plate portion positioned slightly over said circular base plate portion of the platter member, and the circular base plate potion having a supporting column portion which is vertically extended and projected outwardly through said center aperture of base plate terminating with a foot portion, and a barrel portion which intermediates said slanting annular flange portion of an inner peripheral end and a circumferential end of said circular base plate portion and faces toward an interior surface of said second cylindrical portion and defines a vertical annular air-channel;
- said driving motor being housed in said barrel portion of said supporting body member, oriented vertically as defining the interior room of said barrel portion into an upper chamber and a lower chamber, with the driving shaft of said motor being directly engaged with a center spindle of said disc of the platter member;
- and a vertical conduit means adapted for supplying compressed air and for receiving compressed air from a compressor and directing the same into said lower chamber, the vertical conduit means being inserted with said column and foot portion of the supporting body member;
- horizontal orifices formed on said barrel portion of a circumferential side in the range of said lower chamber for leading one part of said compressed air in said lower chamber into said vertical annular air-channel;
- vertical air-channel means for communicating said lower chamber with said upper chamber for passing another part of said compressed air in said lower chamber into said upper chamber, said upper horizontal laminated annular air-channel;
- and vertical discharge orifices formed on said slanting annular portion of said platter member in circumference discharging compressed air from said lower horizontal laminated annular air-channel into an ambient space.
