ABSTRACT:
Apparatus (10) for scanning photographic film includes a scan gate (14, 16, 18, 26-30) having a film track (14) to guide a filmstrip (50) longitudinally in a direction of travel, a film guide surface (26) in the film track, and an elongated scan aperture (28) through the guide surface, the scan aperture being extended transverse to the film track; an image scanning device (18) positioned opposite the scan aperture, the scanning device including a housing (20) with a window (36), the housing enclosing an elongated array (44)of sensors faced through the window toward the film track opposite the scan aperture, the array of sensors having a length (L) and being spaced from the film guide surface; the scanning device further having a transparent cover (42) between the sensors and the film guide surface; the array and the cover being extended transversely to the film track, whereby a passage (48) for a filmstrip (50) is defined between the cover and the film guide surface; a conduit (78, 80)for delivering pressurized air; and a deflector member (58-74) mounted upstream of the passage for deflecting the air into the passage to clean debris from the cover, the deflector member being configured to spread the air into a thin stream moving in the direction of travel, the stream having a width (W) transverse to the film track, the width being at least as long as the length of the array.
