Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
225 words
A printing apparatus for printing an original film on a photosensitive material, comprising: an exposure section; a first pallet for feeding the original film, said first pallet being formed so as to preliminarily accommodate the original film and a mask film in a superposed manner; at least one second pallet provided and formed so as to accommodate a sensitive sheet of a certain size; a third pallet provided so as to collect and accommodate a spent original film and a spent mask film; a fourth pallet for temporarily storing the sensitive sheet, said pallets being movable between a waiting position and a drawn position in which the pallet is above said exposure section and adjacent said waiting position; a pair of guide members mounted on each of said pallets; a pair of guide rails provided between said waiting position and said drawn position of said pallets, said pair of guide rails being engageable with said pallet guide members; a pallet shifting mechanism for selectively moving each of said pallets along said guide rails in a reciprocative manner between said waiting position and said drawn position; and carrier means including a movable plate having suckers for assisting in said reciprocative movement of said pallets, said carrier means also providing vertical movement between a path for said reciprocative movement and an upper side of said exposure section.
Claim 2
Dependent Claim
