Abstract

PURPOSE:To prevent erroneous printing of the printer, by comparing the voltage of the battery for printer driving with the threshold which is set preliminarily and is required for printer driving and by preventing driving of the printer when the battery voltage becomes the threshold or less. CONSTITUTION:The voltage of battery B2 for driving of printer 2 is compared with the preliminarily set threshold by voltage detecting device TC. When signal R of logical 1 is input from the CPU to the FF and the motor for printer driving is turned on, voltage VB2 of battery B2 is lowered. Voltage VB2 is compared with threshold VTH by device TC; and when VB2<=VTH becomes true, signal S of logical 1 is input from device TC to the FF, and signal T of logical 1 is sent from the FF to the CPU. Thus, driving signal P of printer 2 from the CPU becomes 0, and the motor is turned off to stop printing. Consequently, the malfunction due to lowering of the capacity of battery B2 is prevented, and the operator is prompted to battery exchange.
