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.
Claims21
A code reader, comprising:
- a housing including a reading side for reading a code provided on an object;
- means, provided in the housing, for illuminating the code;
- means for capturing an image, provided in the housing;
- and
- means for transmitting light, provided between the means for capturing and the means for illuminating, and having mirror surface characteristics on a first surface thereof and a light transmittance on a second surface thereof,
- wherein the means for illuminating irradiates light from the reading side to the code for reading information contained in the code by a reflection light reflected from the code, and
- the means for transmitting is provided opposite to the reading side.
4 more elements
A code reader, comprising:
- a housing including a reading side for reading a code provided on an object;
- means, provided in the housing, for illuminating the code;
- means for capturing an image, provided in the housing;
- means for restricting incident light entering the means for capturing;
- and
- means for transmitting light provided between the means for restricting incident light and the means for illuminating, wherein
- the means for illuminating irradiates a light from the reading side to the code for reading a reflection light reflected from the code via the means for restricting incident light, and
- means for transmitting is provided opposite to the reading side.
5 more elements
A code reader, comprising:
- a housing including a reading side;
- a light source positioned at the housing to illuminate the code;
- a CCD camera positioned at the housing to receive light reflected from the code, thereby capturing the code;
- a light transmitting member, provided between the CCD camera and the light source at the housing, including a mirrored surface on at least a first portion thereof and a transmitting surface on at least a second portion thereof,
- wherein the light source is configured to irradiate light from the reading side to the code for reading information contained in the code by a reflection light reflected from the code, and
- the light transmitting member is provided opposite to the reading side.
