Abstract
An instant photocopying apparatus has a rod lens array for imaging fine areas of a manuscript on a photosensitive surface of an instant film. The apparatus has a carrier which is movable in a direction parallel to the manuscript. A flourescent lamp illuminates the manuscript. A filter holder is mounted to the lower end of the carrier, and an optical filter is provided for covering a light incidence portion of the rod lens array. The filter is removably mounted so as to enable changing the exposure and tint of the photosensitive surface of the instant film by mounting or dismounting the filter.
Claims8
An instant photocopying apparatus, comprising:
- illuminating means for illuminating an object;
- an instant film disposed in an instant film cassette, said instant film having a photosensitive surface and a printing surface for forming a reverse image of the image imaged on the photosensitive surface as a visible image and wherein the instant film has different exposure characteristics, said instant film including a developer which is applied between said photosensitive surface and said printing surface to thereby develop and fix the instant film;
- optical means mounted to be movable in parallel to said object for imaging fine areas of said object on said photosensitive surface of said instant film and forming an image thereon;
- an optical filter positioned on at least one optical path among optical paths between said illuminating means and said object, between said object and said optical means and between said optical means and said photosensitive surface of said instant film for changing exposure characteristics of said photosensitive surface of said instant film;
- and
- said optical filter being removably mounted in said optical path.
An instant photocopying apparatus, comprising:
- a case having a document plane adapted to be positioned on a document to be copied;
- illuminating means in said case for directing light toward said document plane;
- an instant film disposed in an instant film cassette, said instant film having a photosensitive surface and a printing surface for forming a reverse image of the image imaged on the photosensitive surface as a visible image and wherein the instant film has different exposure characteristics, said instant film including a developer which is applied between said photosensitive surface and said printing surface to thereby develop and fix the instant film;
- said instant film cassette being mounted on said case and having an image plane, said instant film cassette comprising means for holding said instant film in said image plane;
- optical means mounted in said case and movable in a direction parallel to said object, said optical means imaging determined areas of said document plane on said image plane;
- whereby light from said illuminating means is directed in a path extending from said illuminating means, reflected from a document at said document plane, and imaged on said instant film at said image plane via said optical means;
- and
- an optical filler removably mounted in said case in said path.
