Printer with code-controlled tabulator structure
US 3923138 A
Abstract
A format control tabulator structure for a printer is provided with a tabular position memory that can be set or cleared in response to coded input signals; a tabular position memory readout structure is also provided, as well as a tabulation control which is responsive to both input code signals and to readout signals. A form of mechanical structure for the tabulator is shown; it has tab position members designed and located not only to be read out (sensed) to control tabulation termination, but also to cooperate with a carriage position-indicating scale to visually indicate set tabular positions. The same mechanical structure is employed for margin position memory.
