項記載のバッテリバックアツプ制御装置。[Scope of Claim for Utility Model Registration] 1. Means for detecting power outage of the regular power source and load device number 2. As well as supplying power from the source. In a battery backup control circuit equipped with a switch means that switches to supply power from a backup battery when the power supply is cut off, the backup request signal sent from the load device and the power cutoff signal are combined. A backup control circuit characterized in that the switch means is switched by logical product. 2. The battery backup control circuit according to claim 1, wherein the load device generates the backup request signal only during printing operation. 3. Scope 1 of application for utility model registration, in which the load device does not generate the backup request signal when it is idle, but generates the backup request signal during some other operation.
The battery backup control device described in Section 1.
