Abstract
A device for producing photographic prints on a printing medium such as an instant developing film pack from a transparency is provided comprising a housing having an image forming chamber in the forward section thereof containing a lens, a flash tube, opalescent glass plate and a slide holder. A holder for the film pack is located in a rear light-tight chamber formed in the housing and a mirror is located at the bottom of the light-tight chamber angled so as to reflect the image formed in the image forming chamber onto the film pack.
Claims21
A device for producing photographic prints from a transparency on a printing medium having a daylight film rating comprising:
- (a) a housing having an image forming chamber and a substantially light-tight compartment located adjacent said chamber, said compartment having an aperture extending through said housing for allowing an image to be printed on said printing medium;
- (b) a lens extending from said image-forming chamber to said light-tight compartment;
- (c) a reflecting mirror positioned in said light-tight compartment for reflecting an image from said lens to said aperture;
- (d) a source of illumination located in said image-forming chamber, said source having a Kelvin rating which matches the daylight rating of said printing medium;
- (e) an opalescent plate located in said chamber adjacent said illuminating source;
- and
- (f) means located in said chamber adjacent said opalescent plate for holding a transparency.
A device for producing photographic prints from a transparency on an instant developing film pack having a printing medium contained therein, said printing medium having a daylight film rating, said device comprising:
- (a) a housing having a bottom, a forward section, an intermediate section and a rear section;
- (b) a holder for said instant film pack located on said rear section;
- said holder comprising a face section on which said pack rests;
- said face section having an aperture registering with the printing medium of said pack for allowing an image to be printed on said material, and means for retaining said pack in said holder, said holder forming a light-tight compartment in said rear section when said film pack is retained therein;
- (c) a longitudinal housing defining an image forming chamber extending from said forward section to said intermediate section;
- (d) a lens extending from said image forming chamber to said light-tight chamber, said lens having an aperture adjusting annulus;
- (e) a lens aperture adjusting knob mounted on said housing at said intermediate section;
- (f) means linking said annulus and said knob for remotely adjusting said lens aperture;
- (g) a reflecting mirror positioned in said light-tight compartment for reflecting an image to said aperture;
- (h) a flash tube located in said image forming chamber at said forward section;
- said tube having a rating matching said daylight film rating of said printing medium;
- (i) means for energizing said flash tube;
- (j) an opalescent plate located in said image forming chamber adjacent said flash tube;
- and
- (k) means located in said image forming chamber adjacent said opalescent plate for holding a transparency.
A device for producing photographic prints from a transparency on an instant developing film pack having a printing medium contained therein, said printing medium having a daylight film rating, said device comprising:
- (a) a housing having an image forming chamber and a substantially light-tight compartment located adjacent said chamber, said compartment having an aperture extending through said housing for allowing an image to be printed on said printing medium;
- (b) a lens extending from said image forming chamber to said light-tight compartment;
- (c) a reflecting mirror positioned in said light-tight compartment for reflecting an image from said lens to said aperture;
- (d) a flash tube located in said image forming chamber, said tube having a Kelvin rating which matches the daylight rating of said printing medium;
- (e) an opalescent plate located in said chamber adjacent said flash tube;
- and
- (f) means for holding a photographic transparency located in said chamber adjacent said opalescent plate.
A device for producing colored photographic prints from a slide transparency on an instant developing film pack having a printing medium contained therein, said printing medium having a daylight film rating, said device comprising:
- (a) a housing having a bottom, a forward section, an intermediate section and a rear section;
- (b) a holder for said instant film pack located atop said rear section;
- said holder comprising a face section on which said pack rests;
- said face section having an aperture registering with the printing medium of said pack for allowing an image to be printed on said medium, means for retaining said pack in said holder;
- said holder forming a light-tight compartment in said rear section when said film pack is retained in said holder;
- (c) a longitudinal housing defining an image forming chamber extending from said forward section to said intermediate section;
- (d) a 50 mm lens extending from said image forming chamber to said light-tight chamber, said lens having an aperture adjusting annulus;
- (e) a lens aperture adjusting knob mounted on said housing at said intermediate section;
- (f) means linking said annulus and said knob for remotely adjusting said lens aperture;
- (g) a reflecting mirror positioned in said light-tight compartment for reflecting an image to said printing medium;
- (h) a flash tube located in said image forming chamber at said forward section, said tube having a Kelvin rating matching the daylight film rating of said printing medium;
- (i) means for energizing said flash tube;
- (j) an opalescent plate located in said image forming chamber adjacent said flash tube;
- and
- (k) means located in said image forming chamber adjacent said opalescent plate for holding a slide transparency.
