Abstract
A carbon ribbon retaining mechanism includes a barcode-printer base, an upper cover, a printing head device, and at least one pair of resilient fastener elements. The barcode-printer base has an upper portion forming a receiving space. The upper cover is coupled to the receiving space of the barcode-printer base for being downward closed to and covering the receiving space. At least one pawl is respectively formed on opposite edge portions of the upper cover. The printing head device is accommodated in the receiving space. A carbon ribbon retention shaft is arranged above the printing head device. The resilient fastener elements are mounted above the printing head device. By means of the engagement effected between the pawls of the upper cover and the resilient fastener elements, the upper cover is fixed to and above the printing head device to cover the receiving space. Further, by flapping the upper cover upward, the pawls of the upper cover are disengaged from the resilient fastener elements to allow opening of the upper cover and thus expose the carbon ribbon retention shaft for replacement and/or maintenance.
