子機器。 A central processing unit that outputs a mode switching signal that switches the operating state of the fluorescent display tube that makes up the display section between on mode and off mode using a mode setting key, and a central processing unit that outputs a mode switching signal that changes the operating state of the fluorescent display tube that makes up the display section, and a central processing unit that converts the DC input voltage to a constant voltage for display on the fluorescent display tube. A DC-DC converter is connected to the input stage of the DC-DC converter, and the DC-DC converter is connected to the input stage of the DC-DC converter to supply voltage and drive power to the central processing unit.
A mode switching circuit that connects and disconnects the supply of DC input voltage to the DC converter, and a drive voltage that is connected to the input stage of this mode switching circuit and that puts the central processing unit into a standby state based on the DC input voltage in the off mode. and a memory holding circuit that supplies the memory holding circuit to the central processing unit, and a constant voltage means is applied to the memory holding circuit when a switching operation from the off mode to the on mode is performed by the mode setting key or when the power is turned on. A display tube display type electronic device, characterized in that a resistor and a bypass capacitor for supplying a driving voltage to the central processing unit based on the DC input voltage are inserted and connected to the constant voltage means.
