Ribbon cartridge

Abstract

The invention discloses a ribbon cartridge. The ribbon cartridge comprises a box body, a ribbon, a transmission device and an induction device, wherein the ribbon is accommodated in the box body in general, and the ribbon comprises a roll line; the transmission device can receive driving force from a printing machine and drive the ribbon to move along the specific direction; and the induction device is further arranged on the ribbon, and the induction device is arranged beside the roll line. In the ribbon cartridge disclosed by the invention, the ribbon roll line of the ribbon cartridge can get across the printing region of a printing head during working, the phenomenon that the ribbon is broken by impact in the position of the roll line can be effectively prevented, the reliability in printing of the ribbon cartridge is further improved and the service life of the ribbon cartridge is also prolonged.

Description

technical field [0001] The invention relates to a color ribbon box, especially a color ribbon box with an induction device. Background technique [0002] A printing device is a device that transfers electronic information such as text and images to a printing medium. The most widely used printing devices today are mainly laser printers and inkjet printers. However, for some specific fields, such as supermarkets, banks, postal services, etc., ribbon printers still occupy a large proportion. [0003] figure 1 It is an existing ribbon cassette 1 used in ribbon printers. The ribbon 11 is contained in the box, and the ribbon 11 is generally made of a soft and strong fiber strip with ink permeated thereon. The ribbon 11 is usually an endless endless belt, which is realized by lapping and welding the two ends of the elongated ribbon, and the welded part is also called the barge. This structural feature of the annular belt makes the structure and performance of the barge differ...

AI Technical Summary

Problems solved by technology

Therefore, in the actual printing process, the distribution characteristics and uniformity of the ink carried by the port are worse than other parts, and it is also easily damaged by the printing needle of the dot matrix printer due to tissue damage, so that the ribbon is scrapped. As a result, the service life of the ribbon is directly shortened, and the normal use of the ribbon cassette is also affected.

[0004] In order to improve the service life of the ribbon, the usual method is to improve the level of welding technology, but in terms of current technical conditions, the improvement of welding technology is limited by many technical problems, and breakthrough progress is difficult to achieve in a short period of time; One way is to increase the length of the ribbon, for example, increase its length to tens of meters or hundreds of meters on the basis of the existing several meters long ribbon

However, the lengthening of the ribbon is inevitably accompanied by an increase in cost, and at the same time, the increased length is ultimately limited by the volume of the accommodation chamber for the ribbon cassette to accommodate the ribbon, and it is impossible to extend it infinitely
