Abstract:
1. An offline setup recording device, used in an electronic apparatus, comprising: a unidirectional conduction unit; a total energy storage unit, wherein when a power supply supplies a power to the electronic apparatus, the total energy storage unit is charged by the power supply through the unidirectional conduction unit, such that a total voltage is stored in the total energy storage unit; at least an automatically recovering switch, wherein the automatically recovering switch is conductive when the automatically recovering switch is operated by a user, and the automatically recovering switch is open when the automatically recovering switch is not operated by the user; at least a state energy storage unit, wherein when the power supply does not supply the power to the electronic apparatus, the user operates the automatically recovering switch to be conducted, such that the state energy storage unit is charged by the total energy storage unit through the automatically recovering switch, and a storage voltage signal is stored in the state energy storage unit; and at least a reading unit, wherein when the power supply provides the power to the electronic apparatus again, the reading unit receives the power, reads out the storage voltage signal, and outputs a read voltage signal accordingly.
