ABSTRACT:
The present invention includes: a shift register section, including multiple-stage flip-flops operating in synchronism with a clock signal, for switching a shift direction in accordance with an externally supplied direction instruct signal; a waveform change section for changing in waveform a signal output of one of the flip-flops which is in a first predetermined stage; and an inspection signal switching section for switching, in accordance with the direction instruct signal, an output between the signal output which has been changed in waveform in the waveform change section and a signal output of one of the flip-flops which is in a second predetermined stage.
