Abstract
Abstract A transmission data processing device has a memory for storing a series transmission data comprised of each work data with an n-bit word positioning code inserted therebetween and including m-bit letter, numeral and function data, the function and numerical data being capable of taking an n-bit configuration, the function data including together with the word positioning code a code for designating an m-bit configuration in which n is smaller than m. When the n-bit word positioning code is read out of the series transmission data stored in the memory, each data in a group of characters constituting all or part of the word data is read out as an n-bit configuration and, when the n-bit function data for designating an m-bit configuration is read out, each data in a group of characters constituting all or part of the word data is switched from the n-bit to the m-bit configuration and transmitted as such until the next word positioning code is read out.
