A device wherein optoelectronic componentry and circuitry is carried on a single component board (70) mounted in a one-piece case (1) having a main section (10) with a compartment (20) therein for accommodating and holding the board and having at the back thereof a hinged flap (16) defining an opening for inserting the board into the compartment and adapted to lock the board in place when closed, and opposite from the flap, a front end terminal part (50) bounding the front of the compartment and provided with passages therethrough issuing into the compartment for insertion of optical fibers (6, 7) and a clamp (68, 8) for holding the fibers. The device is particularly applicable to equip automatic mail sorting machines.

Optoelectronic detector of passing objects

In an optical mark reader head comprising a light source (57) and two photosensors (58, 59) coupled to light transmission means forming a light emitting head (7) bracketed by two receiving heads (8, 9), all facing the document, and further comprising an analog processing circuit board (50) for the photosensor signals, supporting the light source and the photosensors. The invention provides transmission means in the form of rigid, preformed optical conduits (27, 28, 29) individually assembled and arranged relative to one another and together with the other reader head components in a single, flat case (1).
