Description

The present disclosure relates to bobbins for ink ribbons.

2. Description of the Related Art Thermal transfer printers that print characters, images, and the like on a transfer target such as an image-receiving sheet using an ink ribbon (thermal transfer sheet) are widely used. The ink ribbon has a ribbon (supporting layer) extending in a strip shape, and an ink layer formed on the ribbon and containing a dye or the like. Such an ink ribbon is wound around a supply bobbin, and a used ink ribbon is wound around a take-up bobbin to form a ribbon unit, which is attached to a thermal transfer printer.

By the way, the supply side bobbin and the take-up side bobbin of the ribbon unit each include a cylindrical bobbin body having a pair of ends, and are supported by the support portion of the thermal transfer printer. An RF tag containing print size and lot information is attached to either the supply side bobbin or the winding side bobbin. This RF tag is a storage medium with a built-in memory in the RFID system, and exchanges information between the RF tag embedded with information and a reader/writer installed in the printer by short-range wireless communication. , RF tags have antennas, ICs, etc. inside, and as a result contain metal parts.

The ribbon unit 1 includes a supply bobbin 10 and a take-up bobbin 20. Between the supply bobbin 10 and the take-up bobbin 20 is an ink ribbon (thermal transfer sheet) 3 having a support layer and an ink layer. is provided. The ink ribbon 3 is attached to a supply bobbin 10 and a take-up bobbin 20, respectively. A ribbon unit 1 is composed of the supply side bobbin 10 and the take-up side bobbin 20 , and this ribbon unit 1 is stored in the storage case 2 . Note that the storage case 2 for storing the ribbon unit 1 is not necessarily essential.

The supply side bobbin 10 and the take-up side bobbin 20 are also called an ink ribbon bobbin. be done.

In the ribbon unit 1 configured as described above, the supply side bobbin 10 has a cylindrical bobbin body 10A, and the bobbin body 10A has a pair of ends 10a and 10b.

One end 10a of the bobbin main body 10A is rotatably supported by a bearing 2A of the storage case 2. As shown in FIG. The other end 10b of the bobbin body 10A is rotatably supported by the bearing 2A of the storage case 2. As shown in FIG. A drive gear 12 consisting of a plurality of protrusions 12a engaged with a drive shaft (not shown) built in the thermal transfer printer 50 is formed on the other end 10b of the bobbin body 10A. A bobbin end unit 30, which will be described later, is attached to one end 10a of the bobbin main body 10A.

The take-up bobbin 20 has a cylindrical bobbin body 20A having a pair of ends 20a and 20b. A rotating shaft 23 rotatably supported by is attached. An engagement plate 28 is provided at the other end 20b of the bobbin main body 20A of the take-up bobbin 20. As shown in FIG. The other end 20b of the bobbin body 20A is rotatably supported by the bearing 2A of the storage case 2, and the engagement plate 28 of the bobbin body 20A is locked to the storage case 2.
