ABSTRACT:
An ink supply device for use with a desk type label printing or tagging machine: The machine includes a printing head that is movable up and down for printing the labels of a continuous strip. The ink supply device includes an ink roller for rolling over the type surfaces and an ink roller holding mechanism. A link mechanism is provided for moving the printing head up and down as the ink roller holding mechanism moves back and forth over the types. A guide mechanism, attached in a rocking manner to the printing head, guides the ink roller holding mechanism so that the ink roller applies a preset, constant pressure upon the type surfaces of the printing head. The guide mechanism includes two pairs of guide rollers, which are rotatably attached to both sides of the ink roller holding mechanism, and includes a pair of guide links formed with a pair of guide slots that receive the guide rollers and which are sized and positioned to regulate the spacing during the ink supply operation between the axis of the ink roller and the type surfaces. The guide links are supported by rocking links that define a parallelogram with the guide links.
