DEFINITION

Classification: 353/46

(under the class definition) Subject matter including a projector adapted to project an image which moves on or across the viewing screen.

(1) Note. Usually the object is on a moving tape as in a combined-stock ticker tape and projector.

(2) Note. Subclasses 46+ takes a detailed projector in combination with a nominal stock ticker. The Telegraphy class takes the combination of a detailed stock ticker or other printer in combination with either a detailed or a broadly claimed projector. Class 178, subclass 42 takes the combination of a nominal printer, a nominal projector and a detailed tape-feeding means since Class 226 does not provide for the combination. Class 226 provides for tape-advancing means in combination with a projector when only one optical element is claimed, or in combination with a nominal printer but does not provide for a combination including a projector and a printer.
