Abstract

PURPOSE:To improve handlability eliminating troubles of a backup battery among users of appliances by always detecting an electromotive force thereof to display information on the electromotive force. CONSTITUTION:A signal is outputted to a backup battery 11 to detect the electromotive force thereof from a logical operation control means 1 and inputted into a comparator 10. Then, the signal of the electromotive force is fed back to the logical operation control means 1. Then, the signal of the electromotive force is inputted into a ROM2 and RAM3 and transmitted to a display control means 4. Then, it is transmitted to a refresh memory 6 and the memory contents loaded by scanning to be outputted as video signal. The signal is amplified 7 and shown on a display means 5. For example when the battery electromotive force is set at the minimum 3.0V, the display means 5 shows X mark when 2.4V is reached. Thus, the electromotive force information of the backup battery can be always displayed thereby eliminating fear of trouble among users.

上使い勝手の向上が図れる。This analog value is compared with a battery electromotive force for battery backup by a comparator 10, and the logic operation control means 1
I am entering feedback. With such a configuration, the electromotive force of the battery can be easily detected. Next, if the electromotive force of the battery can be detected, the logic operation control means 1 displays the display means 5 (CRT) from the POM 2 and RAM 3.
The display information to be displayed is transmitted to the display control means 4. The display control means 4 transmits the information to the refresh memory 6, and independently outputs the memory contents as a scan load and video signal. This video signal is transmitted to the display means 5 (CRT) via the amplifier 7, and the display is completed. FIG. 2 shows an example of the display displayed on the display means 5, in which battery electromotive force information is displayed at the left corner of the display means 5 (CRT). The battery electromotive force is 4.3V in FIG. 2(,), and 2.9V in FIG. Since Ov is required, an X mark is displayed. This indicates that the battery needs to be replaced. Since the backup battery electromotive force information is always displayed in this way, it is possible to improve the usability of the device.
