ABSTRACT:
Two rows of plural electrodes are disposed on a base plate, and a contact member is resiliently held against two of the electrodes in the two rows. One of the base plate and the contact member is rotated in unison with an hour hand. Pulses which are successively out of phase with each other are supplied to the electrodes in one row, and a displayed time of the hour hand is detected to produce a corresponding time signal in response to outputs from the electrodes in the other row and the pulses.
