Abstract
A method of reading a bar code formed on an object subjected to information detection employs a plurality of light and dark pattern detecting members which are disposed in the bar code reading direction within the widthwise dimension of a single clock bar in the reading direction. The light and dark pattern of one of the clock bars is detected by one of the light and dark pattern members, and the light and dark pattern of another clock bar adjacent to the first-mentioned clock bar is detected by another light and dark pattern detecting member which is located such as to correspond to the second-mentioned clock bar. The detected light and dark patterns are compared with each other, whereby light and dark portions constituting the bar code are discriminated from each other on the basis of relative brightness. Thus, it is possible to prevent the occurrence of a read error in relation to the light and dark portions of the bar code.
