Abstract
PURPOSE:To obtain a holding circuit not outputting voltage far apart from the voltage at the start time of holding even when a holding state is continued for a long time, by connecting a series circuit of a resistor and a voltage source to a capacitor. CONSTITUTION:This circuit is constituted by connecting a series connection circuit of a resistor 4 and a voltage source 5 to the connection point with the switch 2 of a capacitor 3. When a holding state is continued over a long time, a current gradually flows between the voltage source 5 and the capacitor 3 from the voltage at the start time of holding through the resistor 4 and the charge voltage of the capacitor 3 changes so as to become same to the voltage of the voltage source 5. By this method, even when the holding state is continued over a long time, the voltage at the start time of holding gradually varies to the voltage of the voltage source 5 constituting the series circuit and, therefore, the change to voltage far apart from the voltage at the start time of holding is prevented.
