These arrangements consist of a component carrier (7). Movably arranged segments (1, 4) are connected in each case at one end by segment guides (5). As a result of the rotational movement of a pinion (14) the segments (1, 4) are displaced - starting with the guide segment (1) and the associated sensor (6) or the marking point (41). As soon as the holding segment (4) has reached the pinion (14) the locking spring (8) locks in the locking groove (13) of the holding segment (4) so that an inadvertent displacement of the two segments (1, 4) is avoided. To ensure a reliable locking of the locking spring (8) the braking cam (11) on the support segment (4) has to overcome a spring force of the directional brake (9). The second guide segment (1) is the last segment to be coupled, in accordance with the same sequence - as already shown. The segments (1, 4) are guided back to their starting position as a result of the pinion (14) reversing its direction of rotation. The second guide element (1) runs against the stop pin (12) and thus releases the locking spring (8) from the locking groove (13). The next segment (4) is subsequently pushed in the same direction, followed by the first guide segment (1). <IMAGE> |
