    • A bar code reading apparatus comprises a reading unit for optically reading a bar code and generating an output data corresponding to this bar code, a memory, and a data processing unit for storing the output data from the reading unit into the memory and making a bar code data in accordance with the content of the memory. This reading apparatus further has a mode selection flag (PSF) for selectively instructing either one of the first and second modes, and the data processing unit stores the output data from the reading unit as it is into the memory when the first mode is designated by the mode selection flag (PSF), while the data processing unit stores the inverted data of the output data from the reading unit into the memory when the second mode is set by the mode selection flag (PSF).
    • 条形码读取装置包括读取单元,用于光学读取条形码并产生对应于该条形码的输出数据,存储器和数据处理单元,用于将来自读取单元的输出数据存储到存储器中并使其成为条形 根据存储器内容的代码数据。 该读取装置还具有用于选择性地指示第一和第二模式中的任一个的模式选择标志(PSF),并且当第一模式被指定为第一模式时,数据处理单元将来自读取单元的输出数据原样存储到存储器中 模式选择标志(PSF),而当通过模式选择标志(PSF)设置第二模式时,数据处理单元将来自读取单元的输出数据的反相数据存储到存储器中。
