TECHNICAL FIELD

[0001] The utility model relates to carbon tape measurement technical field, concretely is a kind of carbon tape roll surplus measurement subassembly for scanner. BACKGROUND

[0002] Carbon tape roll, also known as thermal transfer ribbon, is a consumable specially used for thermal transfer printer, which is coated with wax-based, resin or mixed ink on a PET film substrate, and the ink is transferred to a medium such as a label or packaging by a print head, forming a clear and durable text or image. Carbon tape roll is widely used in retail, logistics, medical and manufacturing industries, and is the core material for barcode printing and product identification. When performing printing operations, the remaining amount of carbon tape roll needs to be measured to ensure smooth printing operations.

The code disc has multiple teeth evenly spaced on it, and the teeth are opposite to each other and have a photocoupler. The photocoupler counts once for every tooth rotation of the code disc. This application divides the remaining carbon tape into N gradients and records the corresponding carbon tape roll speed for each gradient. The data is recorded as a table in the machine. During printing, the real-time speed of the carbon tape roll can be obtained through the code disc and photocoupler, and then the corresponding carbon tape surplus can be obtained by looking up the table.
