A scanning circuit has path switches connected between a plurality of data flip-flop circuits of the scanning circuit for sequentially reading an output signal in synchronism with a clock. Also disclosed are pharmaceutical compositions containing such compounds and methods for using these compounds in the treatment of HCV infection. It is ensured that the content can be accessed without the restriction to perform the compliance processing. To smoothly transport a heat-sensitive adhesive sheet without stagnating at a position opposed to a thermal head for thermal activation, even in the case where a non-activated portion is present in a heat-sensitive adhesive layer. The first and second transistors have the same conductivity type.
