Photoplotters

A photoplotting apparatus comprises an internal drum plotter 12 and a media sheet handling apparatus (14) (see Figure 1, not shown) for sequentially delivering a photosensitive media sheet to the photoplotter for exposure from a stack of such sheets. The photoplotter has reduced turbulence within th...

Zusammenfassung:	A photoplotting apparatus comprises an internal drum plotter 12 and a media sheet handling apparatus (14) (see Figure 1, not shown) for sequentially delivering a photosensitive media sheet to the photoplotter for exposure from a stack of such sheets. The photoplotter has reduced turbulence within the drum 22 during exposure of the media sheet, and the sheet handling apparatus includes means for separating the sheets in the stack from interleaves disposed between adjacent sheets (26) in the stack. The turbulence is reduced by an air flow provided from apertures in a tube 54 extending along the length of the drum and fed from a compressed air supply 64.
