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.

Abstract: The invention relates to an attachment for securing an end-part of a toothed belt-element (12, 14) to a machine element (10). The machine element (10) has a slot (18, 16) for receiving an end-part of the belt-element. Arranged on at least one of the opposing walls of the slot is at least one gripping bar (22, 28) which projects into the slot and the cross-sectional shape of which corresponds generally to the cross-sectional shape of a tooth-space formed recess (24, 30) in the end-part (14a, 12a) of the belt element.

Abstract: The invention relates to a device for joining together toothed belt elements (16, 20). The device includes two flat parts (12, 24) which are mutually joined through the medium of a hinge-forming web-part (26). At least one flat part (24) has engagement elements (30, 32) for engagement with corresponding recesses in the belt elements (16, 20), and snap-in locking means (36, 38, 40, 42) are provided for locking the flat parts (12, 24) together.

Abstract: A drive device for a magnetic head (6) reciprocally movable in a slot (8) in a bank printer is suspended on a driving cogged belt (1), the cogged side of which at the same time serving as a covering for the slot to prevent the front edge of an inserted document from catching in the slot (8) in the document-supporting surface ( 7 ). The cogged belt can run with its smooth snide over smooth rollers (2, 3) at either end of the slot.
