Abstract
An arrangement for an image scanning unit (1) includes a semiconductor package (2) so arranged as to generate electrical signals corresponding to an image incident upon the light-sensitive surface (2a) of the package and so arranged as to be connected to a circuit (5) by soldering its contact legs (2b) to the circuit board (5). Also present are an optical system arranged in a holder (3) for projecting the image to be scanned onto the aforementioned light-sensitive surface (2a) and a mounting plate (4) positioned between the semiconductor package (2) and the circuit board (5). Finally, devices (3a, 3b, 4a) are also present for joining together the holder (3) and the mounting plate (4) and for ensuring correct mutual alignment between the semiconductor package (2) and the optical system.
