Abstract
A cartridge ( ) for an injection device carries a code represented by a number of bars ( ) mainly perpendicular to the axis of the cartridge. The bars ( ) are mainly transparent and are each along its whole length provided with an optical grating which diffracts and reflects light impinging the surface carrying the code so that a minor part of this light is reflected from the surface of the bar as a set of light beams of which beams at least one is detected for the indication of the presence of the bar when said bar passes a reading light field. The reflections from the bars may be interpreted as representing “ ”s and “ ”s in a binary code.
