    • An optical code reader which is held in a hand of an operator and is brought near an article having a 2-dimensional code affixed thereto at the time of reading, includes an illumination light source for illuminating the 2-dimensional code on the article, a reading unit for reading the 2-dimensional code from a light reflected by the article, and a frame for housing the light source and the reading unit, the frame having a read window through which the reflected light passes. The reading unit has an area CCD for sensing an image corresponding to the reflected light and for converting the image to an electrical signal, and a lens block for focusing the reflected light to the area CCD to form the image. The reading unit further has an optical path length adjusting cap for adjusting the length of an optical path between the read window and the lens block upon a change in the magnification of the lens block.

    • 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.

    • An optical code reader is held in a hand of an operator and is brought near an article having a 2-dimensional code affixed thereto at the time of reading. The optical code reader includes a read window, a light source for illuminating an article via the read window, and a read control circuit for receiving light reflected by the article via the read window and detecting a 2-dimensional code from an image corresponding to the reflected light. The light source may include a guide beam projector for radiating guide light in a direction almost perpendicular to a read window plane, the guide light indicating a read range corresponding to the size of the read window on a plane parallel to the read window plane. Transparent cap may be provided at the read window for permitting a code on the article to be seen from the outside, while reducing external light entering the cap from the outside of the cap.
