Abstract
PURPOSE:To surely display data which is under adjustment by catching the data, which is under high speed adjustment, in a day latch circuit without displaying the data as it is and making a reading time interval of the latch coincide with a minimum value of the time required for rewriting into ECD. CONSTITUTION:Datum at a digit Di in a clocking circuit 3 is read and held in a latch circuit 8, which is a holding means for an arrival of a periodic read-in signal phi, and it is converted into a signal for lighting of a theta shaped segment by a decorder 9, then, it is displayed at the part of the Dt digit in an ECD displaying device 11 by a driving circuit 10. I the datum stored in the circuit 8 coincides with the clocked datum, a coincidence detecting circuit 12 makes its output Q to be 1 of a logical value. A switching circuit 13 outputs a clock signal phi2 of 5sec period in the ordinary case, and a clock signal phi3 of 0.5sec period in the case of performing the correction as signal phi. Then, a display driving is made at 5sec intervals in the ordinary case and the time is displayed in a 1/2sec period in the case of performing the correction.
