Abstract
The invention relates to a transfer device for generating a regular, linear transfer movement especially for reading an image plate used in X-raying. The transfer device comprises a fixed housing, a rotatable threaded bar (5), a slide (6) moving linearly on the bar, slide guides (9, 10) for controlling the linear movement of the slide, and members for transforming the rotational movement of the bar into the linear movement of the slide. In accordance with the invention, these members consist of two followers (8) elastically articulated in the slide (6) and placed on opposite sides of the threaded bar (5), each of which is provided with a tongue (15) elastically stressed in the threaded groove (7) of the bar, the stressing member consisting of a pull device (19, 21) fitted between the followers and interconnecting the followers elastically in the transverse direction of the threaded bar. The pull device may consist of a magnet (19) and its counterpart (21), or optionally of a draw-spring between the followers.
