Abstract

PURPOSE:To enable to easily detect ''byte drop'' and ''step aside'' of the receiving side, by providing a signal line showing the first or last data of a font data in the longitudinal 1 row, for a system in splitting and transferring a font data. CONSTITUTION:A stroboscopic signal 8 is inputted to a count input terminal UP of a ternary counter 12, it is decoded by a decoder 5, a chip of a memory 6 is selected, and a data 7 is stored in the memory 6. In this case, a longitudinal dot start signal 13 and a decode output signal 16 are inputted to a coinciding circuit 14, and when they do not coincide with each other, it is informed to the transmission side by outputting an error signal 15. Also, when a font data has been received, a signal for discriminating a font data and a code data is made by a font data start signal 17, it is inputted to a reset terminal R of the counter 12, and before the font data is received, the counter 12 is set to zero. In case when ''step aside'' or ''byte drop'' has occurred between each data, one of the signal 16 and the signal 13 becomes a high level and the other becomes a low level, or one becomes a low level and the other becomes a high level, and an error signal 15 becomes a high level due to noncoincidence, and an alarm is raised.
