Abstract
PURPOSE: To simplify the connection between the primary and secondary units of a double-operated clock by using the connection both for the supply of electric power and the transmission of a signal.
CONSTITUTION: The primary unit 1 and the secondary unit 2 are connected by the connections 3 and 4 employed both for the power supply and the transmission of a signal. And, the connection wire 4 is supplied normally with the potential corresponding to the supply voltage of the secondary unit of clock and the power supply line 5 and a smoothing capacitor 10 of the secondary unit are changed to have prescribed potential through the intermediary of a resistance 8 and a diode 9. Next, the wire 4 is supplied with a prescribed train of signals, and during the supply, the line 5 is supplied with the charged voltage of the capacitor 10. By the train of signals if the wire 4, an indicating panel 19 of liquid crystal is driven.
