Title:
【発明の名称】フィルム・パケット・ホルダ―
Document Type and Number:
Japanese Patent JP2533952
Kind Code:
B2
Abstract:
A packet for daylight-handling of photosensitive film and a cooperating holder mountable on a camera back. The packet has film removably attached to a carrier. The carrier has, at one end, an asymmetrical tab bearing adhesive material and, at its opposite end, a transverse light-locking element. Telescopically receivable over the carrier and film is a light-shielding envelope. The envelope has an open end that is closable by engagement with the light-locking element and a closed end with a sealing area that overlies and, when grasped, adheres to the tab, to prevent inadvertent separation of the envelope from the carrier. An adjacent area, not overlying the tab, is graspable for pulling the sealing area free of the tab and the envelope away from the film, to permit intended exposure. The envelope also has, near its open end, a stop strip for limiting envelope movement. The packet is slidably insertable into, and withdrawable from, the cooperating holder, which includes a spring-loaded pressure-applying member for maintaining the film in an exposure plane, a spring-loaded latching member engageable with the light-locking element to retain the carrier in place, a spring-loaded blocking member engageable with the stop strip to limit envelope movement while the carrier is retained, and a releasing member that is manually actuable for negating the spring-loadings on the pressure-applying, latching, and blocking members, to permit unrestricted withdrawal of the packet from the holder.
