Apparatus and method for reading bar code printed card, and bar code recording media card

A bar-code reading system that includes a reading means for reading a medium on which a bar code is printed, by an image sensor having photo-electric conversion elements arranged in line, and a driving means for moving the image sensor, wherein

• the image sensor is moved as the driving means and the an array of the photoelectric conversion elements cross each other at a predetermined angle.

A bar-code reading system that includes a reading means for reading a medium on which a bar code is printed, by an image sensor having photo-electric conversion elements arranged in line, and a transport means to transport a medium, wherein

• the transport means and an array of photo-electric conversion elements cross each other at a predetermined angle.

A bar-code reader that includes a reading means for reading a medium on which a bar code is printed, by an image sensor having photo-electric conversion elements arranged in line, and a transport means to transport a medium, wherein

• the direction of setting the medium at an insertion/removal slot and an array of image cross with each other.

A bar-code reader that includes a reading means for reading a bar-code on a medium by an image sensor having an optical source and an array of photo-electric conversion elements in line, where the array of photo-electric conversion elements is inclined at a predetermined angle and performs a relative movement with the medium to read the bar-code every one line, comprising:

• a reading instruction means for instructing the reading means to read one line;
• a judgment means for making the judgment on the basis of the reading information of at least two lines, and
• a control means for controlling the reading instruction means on the basis of the judgment information.

A bar-code recording medium on which a bar code is printed, wherein

• the bar code is printed so that the bar code and one side edge of the medium crosses at a predetermined angle.

A recording medium for a bar-code reader that transports the recording medium on which a bar code is printed and reads the bar code on the recording medium by an array of photo-electric conversion elements in line, wherein

• the bar code is printed so that it consists of a group of straight-lines which are parallel with each other, and
• the bar code and the direction of transporting the bar code crosses together at a predetermined angle.

A method of reading a bar code having the step of reading a bar code printed on a medium by an image sensor in which photo-electric conversion elements are arranged in line, wherein

• in the step of reading the bar code, the bar code is read under the condition in which the reading line and the bar code cross together at a predetermined angle.
