Impression data-processing apparatus

TL;DR: In this article, a coded data denoting a numeral is formed of 4 bits, and a coded datapath denying a letter is made of a combination of two 4-bit groups, that is, 8 bits; both forms of coded data are stored in a memory.

Abstract: An impression data-processing apparatus, wherein a coded data denoting a numeral is formed of 4 bits; a coded data denoting a letter is formed of a combination of two 4-bit groups, that is, 8 bits; both forms of coded data are stored in a memory; the memory is further supplied with a space data indicating a space on a recording medium and a judgment data for distinguishing between a numerical data and a letter data, said space data and judgment data being constituted by two of those 4-bit codes included in sixteen codes formable from 4 bits which are not used to denote either a numerical data or letter data, and which comprises means for detecting the space data and judgment data in units of 4 bits; bit number read-controlling means for detecting he numerical data and letter data in units of 4 or 8 bits; and printing means for carrying out the spacing of a recording medium when the space code is detected by said space data-detecting means, and printing a numerical data or a letter data read out of the recording medium when a coded data denoting a numeral or letter is detected by said read-controlling means.
