DEFINITION

Classification: 399/64

Optical detector:

(under subclass 62) Subject matter wherein a means or method is provided for detecting concentration by using a light source.

SEE OR SEARCH THIS CLASS, SUBCLASS:

137, for optical intermediate storage of original image.

196+, for variable magnification during exposure.

200+, for automatic adjustment of an optical component due to a change in magnification.

209, for a repositioning of a scanning carriage due to a change in scanning length.

216, for slit exposure by pivoting mirror. 218, for specific lens during exposure.

219, for fiber optics used during exposure.
