     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 9 thereof, a new and improved card spacer apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the card spacer apparatus 10, as indicated in FIG. 1, is mounted within an associated container 11 having a floor 12, spaced side walls 13, a first end wall 14, and a second end wall 15, with a plurality of card plates 16 mounted within the container arranged in a stacked relationship. To minimize the abrasive contact of the cards when in loosely positioned contact relative to one another within the container 11, an abutment structure is included to include a first abutment plate 17 arranged for engagement with the first end wall 14, and the first abutment plate 17 arranged in a biased spaced relationship relative to a second abutment plate 18 arranged for engagement with the card plate 16. Medially and orthogonally directed between the first and second abutment plates 17 and 18 are respective first, second, third, fourth, and fifth tubes 19, 20, 21, 22, and 23 respectively. The second tube 20 is telescopingly received within the first tube 19, the third tube 21 is telescopingly received within the second tube 20, the fourth tube 22 is telescopingly received within the third tube 21, and the fifth tube 23 is telescopingly received within the fourth tube 22. The tubes as illustrated are coaxially aligned relative to one another and arranged for a biased extended relationship relative to one another in a first position and collapsed to a second position, wherein the tubes are arranged for a nested relationship when received within one another. 
     The FIGS. 3 and 4 indicate a manner of providing biased extension of the tubes 19 through 23 relative to one another, wherein the first tube has a second end fixedly, orthogonally, and medially secured to the first abutment plate 17, and a first end including a first annular flange 28 positioned at the first end within the first end, having a first end wall bore 29 directed medially of the first annular flange 28. Further, each first end of the tubes 19, 20, 21, and 22 include a first annular flange 28, as indicated in FIG. 4, having a first end wall bore 29 directed medially thereof coaxially aligned with the tube structure. The tubes 20, 21, 22, and 23 include a second end flange 30 at each respective second end of each of the aforenoted tubes arranged for abutment with a corresponding first annular flange 28, and with a spring interposed between the second end flange 30 of a telescopingly received tube to bias the telescopingly received tube and its associated second end flange 30 into biased engagement with the first annular flange 28 to provide for biased extension of the tubes relative to one another. 
     The FIG. 5 provides for an alternative manner of biasing the tubes relative to one another utilizing pneumatic pressure, wherein the respective first and second annular flanges are biased to one another by pneumatic pressure from the use of a modified second abutment plate 18a. The first through fifth tubes 19-23 respectively are each in pneumatic communication relative to one another and to a second pneumatic conduit 43 of the second abutment plate 18a, that in turn is in pneumatic communication with the first pneumatic conduit 42, that in turn is in pneumatic communication with a pneumatic cylinder 40 within the second abutment plate 18a. Reference to FIG. 7 indicates the modified second abutment plate 18a having a top wall 33 spaced from a bottom wall 44, with the top wall 33 including a top wall recess 35 having a predetermined depth to receive a handle 36 having a predetermined thickness substantially equal to the predetermined depth to nestingly receive the handle 36 within the recess 35. The handle 36 includes a handle rod 37 orthogonally and medially mounted to the handle 36, with the rod 37 directed into the second abutment plate 18a, with the handle rod 37 including a piston 38 mounted to the rod 37 within the pneumatic cylinder 40. The piston 38 includes at least one, and typically a plurality of, piston ports 39 directed through the piston 38. The piston ports 39 are arranged to receive air to be pressurized from inlet ports 47 directed through the top wall recess 35 into communication with the pneumatic cylinder 40 that are below the handle 36. A first flap valve plate 41 is mounted to and below the piston 38, whereupon raising of the piston 38 by means of the rod 37, deflects the flap valve plate 41 from communication with the bottom surface of the piston 38 to permit air directed through the inlet ports 47 and through the piston ports 39 into the pneumatic cylinder 40, whereupon projection of the rod 37 into the pneumatic cylinder 40 compresses air therewithin from the pneumatic cylinder 40 into the first pneumatic conduit 42 and then into the second pneumatic conduit 43 and from there into the first through fifth tubes 19-23. To provide for release of pressure from the tubes 19-23, the first pneumatic conduit 42 extends to the top wall 33, wherein a relief plug 44 is threadedly directed. The relief plug 44 includes a relief plug port 45, with a sealing sphere 46 interposed between the relief plug port 45 and the first pneumatic conduit exit 42a. In this manner, loosening of the relief plug 44 within the top wall 33 permits the sealing sphere 46 to be displaced between the relief plug 44 and the exit port 42a and thereby permitting excess pressure from within the system to be directed through the relief plug port 44 without completely removing the relief plug 44 from the top wall 33. 
     As to the manner of usuage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     There, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
