Zusammenfassung:	It comprises a mover adapted to move forward and backward within the device along a guide shaft constructed by a shaft body including an arc in at least a part of the cross section, following the reading or recording of image information, and bearings through which the guide shaft extends and which are disposed at two positions in a direction of movement differing from the barycentric position in the mover, each bearing having two slopes with the arc of the guide shaft abutting against the cross section, the angles (thetaf (rad)) and (thetar (rad)) which the two slopes of the bearing form with the vertical being such that cos {pi/2-(thetaf + thetar)} > 0. L'invention concerne un élément mobile conçu pour avancer et reculer à l'intérieur d'un dispositif d'imagerie le long d'un arbre de guidage constitué par un arbre dont au moins une partie de la section transversale comporte un arc suivant la lecture ou l'enregistrement de l'information d'image, et des paliers traversés par l'arbre de guidage et situés dans deux positions dans un sens de déplacement différent de la position barycentrique de l'élément mobile. Chaque palier possède deux pentes, l'arc de l'arbre de guidage venant en butée contre leur section transversale et les angles ( theta f (rayon)) et ( theta r (rayon)) que ces deux pentes forment avec la verticale, impliquent l'équation cos { pi /2-( theta f + theta r)} > 0 :
