Abstract
Description
- 1. Field of the Invention
- The present invention relates to barcode printers and, more particularly, to a detachable printing module for use in a barcode printer.
- 2. Description of the Related Art
- Most consumer goods have a scan area printed with a barcode. When scanned with a barcode reader, the commodity number and price are known. A barcode may be directly printed on the packing material of the commodity. Alternatively, the barcode can be printed on a label and then adhered to the commodity. By means of reading the barcode through a barcode reader, the commodity number and price of the commodity are immediately known. A barcode printer for use to print a barcode on a sheet member, for example, a sticker, generally comprises a sheet-transfer unit adapted to deliver a sheet member forwards for printing, a printing mechanism adapted to print a barcode on the moving sheet member, and a toner cartridge (or ink cartridge) adapted to supply toner (or ink) to the printing head of the printing mechanism for printing. When the printing head contaminated with toner (or ink), the printing quality becomes poor. At this time, the printing mechanism must be well cleaned. However, the complicated mounting structure of the printing mechanism does not allow the user to detach the printing mechanism conveniently for cleaning.
- Therefore, it is desirable to provide a detachable printing module for a barcode printer that eliminates the aforesaid problem.
- The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a printing module for barcode printer, which can easily and detachably installed in the barcode printer.
- To achieve this and other objects of the present invention, the printing module comprises an output unit adapted to print a barcode on a sheet member, the output unit comprising a relatively higher first mounting face and a relatively lower second mounting face disposed at a top side thereof, and a connector disposed at the second mounting face; a bottom panel affixed to the second mounting face of the output unit; a locating plate affixed to the first mounting face of the output unit; a holder frame coupled to the locating plate and adapted to secure the printing module to the inside of the top cover of the barcode printer, a reinforcing plate mounted on the top side of the holder frame, and a spring member inserted through an opening at the holder frame and supported between the reinforcing plate and the locating plate to impart a forward pressure to the output unit toward the sheet member to be printed.
