Patent ID: 7606410

Claim:
An image reader module comprising: two or more circuit boards in a stacked configuration, the circuit boards having corresponding notches along adjacent edges and electrical contact points at the edge of the board surfaces connected to circuits on the board; structural supports mounted in the corresponding notches between the circuit boards and arranged to fit within the corresponding notches in the circuit boards to provide structural support between the boards, wherein at least one of the supports is a flex cable arranged to fit securely within the corresponding notches in the circuit boards, the flex cable comprising a plurality of electrical conductors, the electrical conductors being electrically connected to a plurality of contact points on each of the boards for electrically interconnecting the boards, and at least one end of the flex cable extending past one of the circuit boards, whereby the electrical connections between the electrical conductors of the flex cable and the contact points form respective test points for a test probe or connector in testing at least part of the image reader at a manufacturing process.
