ABSTRACT:
In a data inputting apparatus, marks are represented in a matrix form on a surface of a cylindrical data drum. These marks are constructed of characters/symbols, character ornamentation symbols, and character type designation symbols. The data drum is rotated by manipulating a knob to select a mark row containing a desired mark in correspondence with a data selection window, and also the marks present in this selected mark rows are selected in unit of column by operating column selecting keys, thereby selecting a single desired mark. A selection signal of the desired data corresponding to the above-described desired mark is produced by selecting these row and column of the marks. When this selection signal corresponds to the character/symbol mark, data about this character/symbol mark is read out from a font ROM employed in the data inputting apparatus. When either the character ornamentation symbol, or the character type designation symbol is selected, either the character ornamentation symbol mode, or the character type designation symbol mode is set, so that the data are read out from the font ROM in accordance with the font setting mode of the characters/symbols which is selected thereafter. Thus, the read data are printed out on a label tape by operating a return key.
