ABSTRACT:
An ink supply device for an inking type dot matrix printer wherein an ink occlusion body as an ink dipping portion is provided at the extreme end of a printing head, printing wires are inserted through the ink occlusion body to dip tips of the printing wires in ink, and dot-like characters are printed on a sheet of recording paper with the ink. In the ink supply device, the ink occlusion body has an ink occlusion body mounted on the lower surface thereof in a required spaced relation and a pair of detection electrodes for detection of a quantity of ink in a way that a portion thereof is positioned in said space. Each detection electrode is partly in pressure contact with the ink occlusion body. It is controlled so that when a critical output signal generated when detection electrodes are directly connected by ink overflown as the result of a sufficient supply of ink to the ink occlusion body varies, upper and lower limit values for controlling a supply of ink are set so that an optimal quantity of ink may be always supplied to the ink occlusion body.
