PURPOSE:To obtain a series output from a data selector by starting reading data with an optional data number without being affected by a ratio of parallel- serial conversion. CONSTITUTION:Data are outputted from the output terminal 8 of a shift register successively as shown in figure (b) in synchronism with clock pulses supplied to shift registers 6 and 9 in common. At this time, data outputted from respective parallel output terminals 111-114 of the shift register 9 are delayed by one clock pulse period. Namely, data #0 is outputted from the terminal 111 with a clock pulse #5, and data #0 is outputted from the terminal 112 with a clock pulse #6; and data #0 is outputted from the terminal 113 with a clock pulse #7, and data #0 is outputted from the terminal 114 with a clock pulse #8. A clock pulse #8 and succeeding pulses correspond to an effective operation period. Namely, data having an optional data number are obtained at parallel output terminals 111-114 at the same time with the clock pulse #8 and succeeding pulses. |
