Abstract:
    The utility model provides a tax controlled cash register, including main circuit board, the main circuit board master control unit and serial interfaces which electrically connect with main master control unit, keyboard interface, IC card interface, printer drive circuit, display interface and control circuit respectively, among of them, the tax controlled cash register still includes one memory board, the memory board is provided with data storage unit, the memory board electrically connects with main circuit board as a splicing device. Since the utility model is a tax controlled cash register data storage unit that is separately made into one memory board splicing on the main circuit board, as a consequence, it can correspondingly mate different volumetric memory board according to different tax controlled cash register application field or performance requirement, therefore, it can shorten design and production cycle of products, and reduce cost.
