That which is claimed is: 1. A juice extractor comprising: an extractor frame having an interior and opposing side panels for dividing the interior into a product area and opposing drive mechanism cavities, each of the drive mechanism cavities is extended between one of the inner side panels and an outer cover of said extractor frame; at least one pair of extractor cups being relatively movable for compressing fruit therebetween; and a drive mechanism engaging at least one of the extractor cups and driving the extractor cup into engagement with the other extractor cup of the pair, said drive mechanism comprising two drive cams for driving an extractor cup of the pair of extractor cups into engagement with said other extractor cup and two return cams that drive the pair of extractor cups out of engagement, the return cams are positioned between the drive cams. 2. A juice extractor according to claim 1, wherein said return cam comprises a mathematical conjugate of the drive cam. 3. A juice extractor according to claim 1, and further comprising a plurality of pairs of extractor cups that are ganged together. 4. A juice extractor according to claim 1, and further comprising a camshaft that supports both said drive cams and return cams. 5. A juice extractor according to claim 1, wherein said extractor cups are arranged in vertical opposed relationship forming upper and lower extractor cups. 6. A juice extractor according to claim 1, and further comprising a cam follower train operatively connected to said return cams for disengaging the extractor cup. 7. A juice extractor comprising: an extractor frame having an interior and opposing side panels for dividing the interior into a product area and opposing drive mechanism cavities, each of the drive mechanism cavities is extended between one of the inner side panels and an outer cover of said extractor frame; a plurality of extractor cups positioned within said extractor frame; a cup support member mounted for reciprocating movement within said extractor frame; said plurality of extractor cups supported by said cup support member; a camshaft mounted for rotation within said extractor frame; a drive mechanism connected to said camshaft for rotating said camshaft; and two drive cams mounted on said camshaft and operatively connected to said cup support member to drive said cup support member and driving said extractor cups into engagement with a plurality of fixed extractor cups to compress fruit and two return cams mounted on the camshaft and operative for driving the extractor cups out of engagement from said fixed extractor cups, the return cams are positioned between the drive cams. 8. A juice extractor according to claim 7, and further comprising a bridge mounted within said extractor frame to support said fixed extractor cups. 9. A juice extractor according to claim 8, and further comprising an integrated bridge and juice manifold that supports said fixed extractor cups. 10. A juice extractor according to claim 7, wherein said return cam comprises a mathematical conjugate of the drive cam. 11. A juice extractor according to claim 7, and further comprising a cam follower train that is operatively connected to said return cams and cup support member, which is reciprocated by said return cams. 12. A juice extractor according to claim 7, wherein said camshaft is mounted at an upper portion of said juice extractor. 13. A juice extractor according to claim 7, and further comprising a drive gear mounted to an end of said camshaft, said drive mechanism engaging said drive gear. 14. A juice extractor according to claim 13, and further comprising a gearbox in which said drive gear is mounted. 15. A juice extractor according to claim 7, and further comprising a strainer tube mounted to receive juice and pulp of fruit, an orifice tube movable within the strainer tube, and a drive mechanism engaging the orifice tube for reciprocating the orifice tube within the strainer tube, said drive mechanism including an orifice tube drive cam mounted on said camshaft, and a drive linkage engaging the orifice tube and orifice tube drive cam. 16. A method for forming a juice extractor, the juice extractor comprising an extractor frame having an interior and opposing side panels for dividing the interior into a product area and opposing drive mechanism cavities, each of the drive mechanism cavities is extended between one of the inner side panels and an outer cover of said extractor frame, and a drive mechanism that engages at least one pair of extractor cups for moving an extractor cup into engagement with the other extractor cup and compressing fruit therebetween, the method comprising: forming the drive mechanism as two drive cams for driving the extractor cup into engagement with the other extractor cup and two return cams for driving the extractor cup out of engagement from the other extractor cup, and positioning the return cams are positioned between the drive cams. 17. A method according to claim 16, which further comprises forming the return cam as a mathematical conjugate of the drive cam. 18. A method of operating a juice extractor, the juice extractor comprising a moveable extractor cup, a fixed extractor cup, two return cams positioned between two drive cams, and an extractor frame having an interior and opposing side panels for dividing the interior into a product area and opposing drive mechanism cavities, each of the drive mechanism cavities is extended between one of the inner side panels and an outer cover of said extractor frame, the method comprising: driving the moveable extractor cup into engagement with the fixed extractor cup using the drive cams for compressing fruit between the extractor cups; and driving the moveable extractor cup out of engagement from the fixed extractor cup using the return cams. 19. A method according to claim 18, which further comprises forming the return cam as a mathematical conjugate of the drive cam.
