Tape cartridge system
Abstract
Abstract A CARTRIDGE PLAYER INCLUDES TWO SETS OF CAMS FOR CONTROLLING THE POSITION OF A REPRODUCING HEAD TO REPRODUCE THE INFORMATION ON EITHER FOUR TRACK OR EIGHT-TRACK TAPE CARTRIDGES, AND A FEELER ARM AND ASSOCIATED LINKAGE FOR AUTOMATICALLY SWITCHING BETWEEN THE CAMS UPON THE INSERTION OF EITHER FOUR-TRACK OR EIGHT-TRACK CARTRIDGES. AFTER THE FOUR TRACK OR EIGHT TRACK CARTRIDGE IS INSERTED, AN ACTUATING MEMBER IS CONTROLLED BY A SWITCH ON THE FRONT PANEL OF THE MACHINE TO ROTATE THE APPROPRIATE CAM TO PRESENT DIFFERENT CAMMING SURFACES TO CONTROL THE POSITION OF THE REPRODUCING HEAD. THE PLAYER ALSO INCLUDES A LOCKING MEMBER HAVING AN ACUTE FORWARD FACING ANGLE PORTION WHICH IS MOUNTED AT THE END OF A RESILIENT MEMBER SO AS TO LOCK THE EIGHT-TRACK CARTRIDGE WHILE PERMITTING THE EASY INSERTION OF THE PINCH ROLLER FACILITATES THE REMOVAL OF THE FOUR TRACK CARTRIDGE FROM THE PLAYER.
