Abstract

PURPOSE: To simplify the scanning driving circuit of a printer unit to record information by converting character information signals, which are read in horizontal and vertical scanning speeds of a high-speed TV receiver, into the scanning speed of a low- speed printer.
CONSTITUTION: When picture data to form signals for displaying luminus points of a TV receiver scanning the screen regularly is converted into the scanning speed of printer PRT which prints and records it, coincidence circuit 12 which detects coincidence between printer display line counter 15, which counts printer display lines, and TV display line counter 11 and memory 3 where write data is inputted are provided. Then coincidence between counters 11 and 15 is detected to output a read/write signal to the output of gate 13, and gate 7 is controlled by this signal to write and store one-horizontal line components of picture data into memory 3 in the scanning speed of the TV receiver. This stored picture data is read in the scanning speed of printer PRT and is applied to printer PRT, and this scanning is repeated to record character information, which is read in a high speed, onto printer PRT.
