Abstract: A code reader is configured to reads information unique to an object from a code (e.g., one dimensional code, two dimensional code, three dimensional code, or multi-dimensional code combined with different codes, hereinafter referred to as a code) by providing the code directly or indirectly on the object in order to identify the particular object (e.g., a product) among the plural objects made of metal, rubber, ceramic, and resin, or the like.

Abstract: A code reader includes: a housing including a reading portion for reading a code provided on a surface of an object; image capturing means provided in the housing for capturing an image of the code; light generating means including a light source provided in the housing for irradiating an illumination light to the code; light restriction means for restricting an amount of reflected illumination light, reflected after contacting the code, that enters the image capturing means; and a flexible board provided on the housing, on which the light source is positioned.

Abstract: An anti-theft device for a vehicle includes a code including the unique information and a reference code memorized in a vehicle. The start of an engine is allowed when the unique code is identified with the reference code. The unique code is provided on an ignition key and the unique code includes portions including different reflective ratios when a light is irradiated.

Abstract: A code reader includes a housing, a reading portion, provided on the housing, for reading a code provided on an object; a device, provided in the housing, for illuminating the code a device, provided in the housing, for capturing an image of the code; the device for illuminating the code irradiating a light to the code for reading information of the code by a light reflected from the code; and a light transmission member, provided between the device for capturing the image and the reading portion, for introducing the light generated by the device for illuminating the code.

Abstract: A code reader which includes a housing; a reading portion, provided on the housing, for reading a code provided on an object; an illumination device provided in the housing; an image capturing device, provided in the housing, for imaging the code, the illumination device irradiating light to a surface to be read provided with the code reflecting the irradiated light, the image capturing device configured to be entered with the reflected light via an entrance pupil provided in the housing, the image capturing device being configured to read information of the code, a diffusion member for permeating and diffusing the light from the illumination device and for irradiating the diffused light to the surface to be read, the plural illumination device positioned opposite each other relative to the entrance pupil, and the diffusion member positioned between the illumination device and the reading portion.
