Abstract
A method of reading a bar code printed on a photographic film cartridge in which the bar code has a certain arc length on the cartridge. The cartridge is transported on a conveyor and positioned on the conveyer so that the normal line intersecting at the middle point of the arc length forms an acute angle to the transporting direction of the conveyer. The bar code is irradiated with a light beam of a bar code reader while the cartridge is transported on a conveyer, and the irradiating angle with the transporting direction is determined smaller than the acute angle of the normal line intersecting the bar code.
