发明名称 Inked ribbon advancement mechanism
摘要 The present invention is an inked ribbon advancement mechanism which is used in combination with a printer having a movable print head. The printer includes a frame and a print head mechanically coupled to the frame so that it travels laterally along the front of the frame. The inked ribbon advancement mechanism includes an apparatus for continuously advancing an increment of inked ribbon in response to the position of the print head. The apparatus includes a device for positioning the increment of inked ribbon adjacent to the print head and a slidable member which is slidably coupled to the print head in parallel juxtaposition so that the slidable member can move differentially in response to the print head. The apparatus also includes a cam for continuously displacing the slidable member in response to the movement of the print head. The print head is mechanically coupled to a plate member to which a pair of ribbon spools are rotatably coupled so that the print head and the increment of inked ribbon from the ribbon spools travel together.
