Abstract
A battery-driven recording apparatus records a plurality of lines by recording-scan by using a recording head having a plurality of recording elements. A capacity of a battery is detected, and when the capacity of the battery is lowered, the number of lines to be recorded in one recording scan is reduced.
Claims5
A recording apparatus comprising:
- a recording head having a plurality of recording elements, for recording an image on a recording medium;
- scan means for causing said recording head to perform a recording scan, wherein said recording head records an image having a width corresponding to said plurality of recording elements by performing one recording scan;
- a battery for supplying power to said recording head, an output voltage of said battery decreasing dependent upon consumption;
- detection means for detecting the output voltage of said battery;
- and
- control means for changing a quantity of data to be recorded in one recording scan in accordance with the output voltage of the battery detected by said detection means, wherein said control means reduces a number of recording elements to be used in one recording scan when the output voltage of said battery decreases below a predetermined value.
