Abstract

PURPOSE:To enable to greatly prolong the useful life of a power source such as a battery, by a method wherein the operation of a DC-DC converter for operating a head and various driving motors is stopped when the output therefrom is not used. CONSTITUTION:When the subsequent printing data C are not inputted into a CPU2 after throwing in a power source or after completion of a printing operation, a line-feeding operation or the like, an operation-stopping signal S1 is outputted to stop the operation of the DC-DC converter 1 until the subsequent printing data are inputted. When the subsequent printing data C are inputted, an operation-starting signal S1 is outputted to start the operation of the converter 1, thereby processing the printing data C. In this case, when the amount of the printing data C is small, the processing is completed before an output voltage of the converter 1 is reached, resulting in that drive-controlling signals are outputted to the head 4 and the motor 5. To avoid this problem, the printing operation is effected by a signal S2 outputted when it is detected by a detecting circuit 3 that a prescribed voltage is reached. Accordingly, the power source such as a battery can be prevented from being consumed due to a reactive current.

However, with conventional printers, the DC-
The DC converter was operating in oscillation. Therefore, even if the load current is O, there is a reactive current of about 2 to 3 (mA) depending on the power consumption of the DC-DC converter itself. Generally, a printer spends more time inactive than it does in printing, so the presence of reactive current cannot be ignored. Especially in Zorin 4 with battery drive, Ba 9. This will cause the lifespan of the telly to be drastically reduced.

i) Even if the function is finished, the function will not start until the detection signal S1 from the detection circuit 3 is input. That is, the detection circuit 3 should check whether the output voltage vcc2 of the converter 1 has reached the specified voltage (Sr1), and if it has not reached the specified voltage, the detection signal S1 will not be output, so it is determined as No, and the specified voltage is not reached. When the voltage reaches the voltage, a detection signal sl is output, and the CPU 2 determines that the voltage is "Yell" and starts the function (Sr1).
