Claims

[Claims for Utility Model Registration] (1) In an electronic device with a built-in battery, an A/D converter that digitally converts a battery voltage or an operating voltage proportional to the battery voltage;
a storage means for storing digital signals of the A/D converter; a control means for reading and outputting data stored in the storage means in response to a display instruction signal; and a display instruction means for outputting a display instruction signal to the control means; A voltage display device for an electronic device with a built-in battery, comprising a display device that digitally displays an output signal of a control means as battery voltage data. (2) The storage means stores a minimum voltage value of the battery that can guarantee normal operation of the electronic device, and the control means compares the battery voltage value at that time with the minimum voltage value and determines the difference. A voltage display device for a battery built-in electronic device according to claim (1) of the utility model registration, which outputs warning information to a display device when the voltage falls within a certain range. (3) The storage means stores voltage drop characteristics of the battery with respect to the operating time of the electronic device, and the control means reduces the battery voltage to the lowest voltage value that can guarantee normal operation of the electronic device based on the voltage drop characteristics. A voltage display device for a battery built-in electronic device according to claim (1) or (2) of the utility model registration claim, which calculates the time required for the battery and outputs the time data to a display device. (4) Claims (1), (2), or (3) for utility model registration in which the display instruction means automatically outputs a display instruction signal when the electronic device is powered on. Voltage display device for electronic equipment with a built-in battery as described in item ).
