Abstract
PURPOSE:To use the display function of a display equipment itself to confirm the capacity of a battery, by displaying the capacity of the battery by lighting a prescribed number of digits or digit positions on the display equipment. CONSTITUTION:The current of a battery B is input to a control circuit L through a DC/DC converter C and is further input to a printer P through a printer driving circuit A. Meanwhile, the signal from a keyboard K is subjected to operation and control by a circuit L, and the result is displayed on the display equipment and is printed as prescribed by a printer P. In this case, a timing pulse is generated by a timing pulse generator TPG and is sent to a pulse period detecting circuit DET. Consequently, if the capacity of a battery B is lowered, the period of the timing pulse formed by the TPG becomes long. This period is detected by the DET, and a small number of digits are lit on a display equipment D in accordance with the detection result. Meanwhile, if the capacity of the battery B is not lowered, a large number of digits are lit on the display equipment D.
