• means for pivotally mounting said cartridge load tray to said housing;
• said cartridge load tray in combination with said pivotally mounting means having:
• a forward position above said rotating means and entirely within said housing, said tray in said forward position is adapted to receive and hold the cartridge above said rotating means;
• a middle position above said rotating means, said tray in said middle position is adapted to hold the cartridge in a first seated position on said rotating means;
