Instant camera using self-developing film cassette - has light blocks adjacent developed film sheet outlet to prevent light penetrating nip between rollers

摘要

The instant picture has a pair of rollers (8, 9) for forwarding each exposed sheet from the camera. Befor and/or after this pair of rollers (8, 9) are light blocks (12) for blocking light passing through the nip between the rollers. The light-blocks (2) have approx. the same refractive index as the protective foil (6) for the exposed sheet and contact the protective foil (6) across its entire width. Pref. the light blocks (12) comprise a strip of dark coloured opaque resilient plastics, or a felt strip using plastics fibres.
