A signal conversion circuit is used to convert a parallel signal to a serial signal and comprises a parallel input/serial output type of shift register having input terminals corresponding in number to at least n+k bits (n and k: integer), an inverting circuit and a timing circuit. The n-bit input parallel signal is applied to n successive input terminals of the shift register and k bit of the n-bit parallel signal is inverted by the inverting circuit to be applied to the remaining k input terminal of the shift register. The (n+k)-bit parallel signal loaded into the shift register is serially output at a predetermined rate by the timing circuit to provide a serial signal.
