Abstract

Proposed is an apparatus for handling and drying sheets which contain wet ink jet images. As shown in the accompanying Fig., a sheet conveying and drying device 20 is shown having a plurality of flexible, resilient, yet stiff fingers 21 connected in a cantilevered manner to a drive chain 27. The drive chain 27 moves the fingers 21 from a printed sheet receiving tray 55 to a sheet stacking tray 16. After sheets are printed by a conventional ink jet printing head (Not Shown), the sheets are picked off of the printed sheet receiving tray 55 and fed to a sheet stacking tray 16. The printed sheets are dried while being fed from the printed sheet receiving tray 55 to the sheet stacking tray 16. After the printed sheets are picked off of the fingers 21, at the sheet stacking tray 16, the chain drive 27 continues to move the fingers 21 in a counterclockwise direction along the chain path. The resilient, flexible fingers 21 are deformed by: upper guide rollers 30, lower guide rollers 31 and 32, a stacking tray 16, and an arcuate rear separating wall 17. The fingers 21 are flicked back into a sheet receiving position at the printed sheet receiving tray 55. The speed at which the chain drive 27 moves the fingers 21 can be varied by a motor 35 to ensure that the images are dried by the time they reach the sheet stacking tray 16.
