Snap On Paper Handling Apparatus

Paper is automatically loaded, and unloaded and stacked, in either an attended or unattended printing system. This is facilitated by a snap-on device controlled by the printing system.

A stack of sheets 1 is manually positioned on platform 2. For feeding the top sheet for printing, picker roller 3 carried by cantilevered arm 4 is rotated. This causes the top sheet to be fed to the left and between feed rollers 5 and 6. From there, the sheet is fed through gap 7 formed by rails 8 and 9 and back to the right between rails 9 and 10. When the sheet is picked up by reversible rollers 11 and 12, it is driven further to the right. When the trailing edge of the sheet clears gap 7 and is between rails 9 and 10, rollers 11 and 12 are reversed for driving the sheet back in a downward and leftward direction between rails 10 and 13. This brings the sheet into engagement with platen 14 for positioning the sheet at the first writing line.

After the sheet has been printed, platen 14 is reversed and the sheet is driven back to the right between rails 10 and 13 by platen 14 and roller 15. The sheet continues being fed to the right and on between rails 9 and 10. Eventually the sheet is picked up by rollers 11 and 12 and fed further to the right. When picked up by rollers 16 and 17, the sheet is fed into a hopper having a platform
18.

Referring again to picker roller 3 and cantilevered arm 4, arm 4 is pivotable about point 19 and picker roller 3 is n...
