Abstract
A code reading device including: an article placement surface on which an article is placed; at least one code reading unit that optically reads a code attached to the article; and a motion unit that causes the article to swivel and/or rotate on the article placement surface, the code reading device being configured to read the code with the code reading unit while causing the article to swivel and/or rotate on the article placement surface.
Claims14
A code reading device comprising:
- an article placement surface on which an article is placed;
- at least one code reader that is configured to optically read a code attached to the article;
- and
- an article mover that is configured to controllably change a biasing direction of the article placed on the article placement surface which moves to thereby drive the article so as to thereby cause the article to swivel and/or rotate in a predetermined manner,
- the code reading device being configured to read the code with the at least one code reader while causing the article to swivel and/or rotate on the article placement surface,
- wherein the article mover comprises a plurality of conveyance cells arranged in a planar state, wherein each conveyance cell has a moving function of moving the article and a conveying direction change function of changing a conveying direction,
- wherein the at least one code reader includes at least one lower code reader that is configured to read the code from a lower side of the article placement surface,
- wherein the code reading device is configured to read the code with the lower code reader,
- wherein the article placement surface includes a gap, and wherein the lower code reader is installed in a posture to look through the gap.

- the at least one code reader including an upper code reader and a lower code reader,
- the upper code reader being provided above the article placement surface,
- the lower code reader being configured to read the code by monitoring from below the article placement surface,
- wherein the article mover comprises a plurality of conveyance cells arranged in a planar state,
- wherein each conveyance cell has a moving function of moving the article and a conveying direction change function of changing a conveying direction,
- wherein the article placement surface includes a gap, and
- wherein the lower code reader is installed in a posture to look through the gap.
9 more elements
A method for reading a code attached to an article, comprising:
- (a) placing the article on a surface;
- (b) controllably changing a biasing direction of the article placed on the surface by moving the surface to drive the article so as to thereby cause the article placed on the surface to swivel and/or rotate in a predetermined manner;
- (c) reading the code from an upper surface side and a bottom surface side of the article as the article is swiveled and/or rotated,
- wherein step (b) includes swiveling and/or rotating the article on an article placement surface having a gap, and
- wherein step (c) includes reading the code from the bottom surface side through the gap.
