    • An optical reading apparatus for reading a two-dimensional symbol includes a housing having an opening portion for confronting the symbol, a gripping portion, and a serial I/F for transmitting a two-dimensional code data corresponding to the two-dimensional symbol to an external apparatus. LEDs mounted near the opening portion generate light to illuminate the two-dimensional symbol. A mirror reflects light reflected from the two-dimensional symbol toward the gripping portion. An automatic diaphragm mechanism regulates the light from the mirror. A two-dimensional type CCD generates electrical signals corresponding to the regulated light. Image processing circuits convert the electrical signals to the two-dimensional code data.
