Abstract

PURPOSE:To prevent the malfunction for generation of a reset signal, by operating a control means in accordance with the reset signal, which is obtained from the bit synchronizing signal of character pattern information, to control the input of character pattern information to a series-parallel conversion means. CONSTITUTION:An FF circuit 22 generates a gate signal E, by which character pattern information is inputted to a series-parallel converting circuit 6 through a gate circuit 21, from the Q terminal by a reset signal C from a reset pulse generating circuit 2 connected to the S terminal and a set signal D, which is generated by detecting the horizontal synchronizing signal after the arrival of character pattern information, from a control signal generating circuit 9 connected to the R terminal. As the result, the gate circuit 21 is conductive to pass character pattern information from a waveform shaping circuit 1 through, and this information is inputted to the series-parallel converting circuit 6. Since character pattern information is applied to the series-parallel converting circuit 6 by the generation of the reset signal obtained by detecting a bit synchronizing signal RI, the input of the bit synchronizing signal before the generation of the reset signal is stopped.
