Abstract

The printer comprises selectively settable type fonts for printing bar coded characters. It is particularly suitable for use in a lightweight portable printing mechanism for on site printing of bar coded characters on labels, suitable for attachment to merchandise which is to be sold at the site. The bar code shown in Fig. 1, is an illustrative example of many different codes which could be implemented.

Bar Code Printer

The printer comprises selectively settable type fonts for printing bar coded characters. It is particularly suitable for use in a lightweight portable printing mechanism for on site printing of bar coded characters on labels, suitable for attachment to merchandise which is to be sold at the site. The bar code shown in Fig. 1, is an illustrative example of many different codes which could be implemented.

To print several characters in a row, the first bit S1 of a following character is positioned immediately following the last bit S9 of the preceding character. In the printer, as many thumbwheels 10 are settable under operator control as individual characters are to be encoded in one printing cycle. The thumbwheels are adjacently arranged in a row and protrude through the top of the printer cover. Selective setting of type fonts 11 for bar code printing in station 12 is achieved, by rotational positioning of each of thumbwheels 10 into the desired character position.

To illustrate the interactive operation of the settable elements, Fig. 2 depicts a side elevation of a single thumbwheel 10 and one of a plurality of associated cams 13 with its cooperating type font carrier 14. Wheel 10 has finger recesses 15 bearing the fifteen different character designations 0 - 9 and A - E in visible form. Notches 16 in cooperation with detent 17 lock wheel 10 in the selected position. Wheel 10 and cams 13 are mounted on support shaft 18 for equal rotational movement. Each cam 13 controls a type font carrier 14 and causes it to reside in o...
