  • the drawer includes a platform supporting a stack of sheets.
  • the platform is resiliently urged in an upwardly direction so that the stack engages the feed rolls.
  • a detent secures the platform in a depressed position.
  • the platform is manually moved to the depressed position permitting loading of a stack of sheets therein.
  • the detent releases the platform.
  • the platform is resiliently urged in an upwardly direction so that the stack thereon engages feed rollers.
  • a base plate supporting a stack of sheets thereon is resiliently biased so that the stack of sheets contact a separation belt.
  • the separation belt cooperates with a retard pad to advance suc' cessive sheets from the stack disposed in the base plate.
  • None of the foregoing prior art devices actuate the sheet feeding apparatus or electrophotographic printing machine in response to the sheet feeding apparatus being moved to the operating position. Moreover, no prior art devices appear to automatically move the stack of sheet material from engagement with the sheet separating and advancing apparatus as the sheet feeding apparatus is moved from the operating position to the loading position. This enables the sheet separating and advancing mechanism to remain substantially stationary permitting each successive sheet to be advanced along substantially the same path of travel. In addition, no apparatus appears to be disclosed in the prior art for automatically locking the sheet feeding apparatus in the operating position.
