Estimating the term…
A photoprinting apparatus in which images of symbols on a flat transparency font are projected upon photosensitive material covered by a thin layer of photographic developer. Each symbol on the font is provided with a baseline control indicia and a selected symbol may be projected and viewed prior to exposure employing a light source which will not expose the photosensitive material. Baseline uniformity of the exposed symbols is maintained by sensors which receive an image of the control indicia and regulate the operation of font position adjusting devices prior to each exposure. Novel optical systems, image magnification and minification structures, exposure controls, rapid symbol selection devices, imaging fonts and a cassette for the photosensitive material are also disclosed.
A photoprinting apparatus comprising:
A photoprinter imaging font comprising a transluscent plannar sheet, a plurality of equally spaced symbols on said sheet, symbol orienting indicia for each symbol, each of said indicia being spaced from the optical center of its symbol an identical distance and spaced position locating and securing means adjacent at least one margin of said sheet.
A cassette for a supply of photosensitive material in rolled strip form comprising a hollow housing, a container portion for said housing having a bottom and an upstanding wall around the bottom to receive a roll of photosensitive material therein, an outwardly directed flange on the rim of the said wall, a cover for said container portion, a depending lip on said cover overlying the rim of said container portion, an outwardly directed flange on said lip cooperatively positioned with said container flange to receive and guide one end of strip material from the cassette, and guide means comprising a fin shaped member secured within the cassette in the path of the strip and carried by the cover within the cassette to cause the strip to change its orientation by 90.degree. as it is led out of the cassette through the said flanges.
