Abstract
PURPOSE: To display beforehand whether the battery voltage will be proper or not when a large load is burdened by providing a test load corresponding to a large load and detecting the power supply voltage condition when the load is burdened, by means of a detector circuit.
CONSTITUTION: Power supply battery 1 is connected with CPU2 and motor 3 for use with a printer-fitted desk calculator, further it is connected with test load 5 corresponding to a printer load and battery voltage comparator 6. Before motor 3 is driven, test load 5 is applied by turning on switch SW. By this, LED8 is lit by comparator circuit 6 when the battery voltage is sufficient, and LED8 is kept extinguished when the battery voltage is insufficient. Consequently, even if a power supply battery having a large internal impedance, such as a manganese battery, is used, it is possible to know easily beforehand whether it is possible to operate a printer or not.
