Abstract: The arrangement comprises guide units (1) having an arcuate groove (4), a pivotal part (2) with arcuate slide runners (14) and means (6) for the adjustment of the width of the groove. In this way a self-locking can be achieved with simple means in advantageous manner. A function carrier for an objective carrier or an image carrier with this arrangement has the advantages of the omission of a setting device for the horizontal pivoting and the associated saving in weight and height in a plate camera and also a wobble-free pivoting of the objective frame and image frame.
