- 18 - ABSTRACT IMAGE PLATE SCANNER In order to improve an image plate scanner (10) for a device for scanning a circular videodisk (12) exposed by X-rays with image elements (40) spaced a distance (radius R) away from the videodisk central point, by means of laser beams, with a video- disk carrier (13) which is drivable with the aid of an electro- motor (11) with adjustable rotation speeds and on which the videodisk (12) is detachably mounted, with an image element scanning unit (15;115) which by means of a drive assembly (14,18) with presettable speed of advance, is radially displa- ceable across the videodisk (12) and a laser light supply means (42) and an optical image element scanning facility (30a) of an optoelectronic measured value transmission means with a photomultiplier (36) and with a signal conditioning means, in such a way that, during the light scanning for recording the image stored on the videodisk, a maximum light yield is obtai- ned for the emitting light, in which connection the image plate scanner is at the same time intended to be constructed in a compact manner so as to facilitate the operation, it is proposed that the image element scanning unit (15;115) can be guided across the videodisk while scanning each image element (40) at the same tangential speed, provision being preferably made for the laser light supply means (42) to be provided with a collector lens (44) which is acted upon by two laser light sources (43a,43b) via an optical filter (46), by means of which the laser light is focussed and in that the drive shaft (18) of the electromotor (11) is connected with a power spindle (26) by means of a gear drive (23), with the aid of which the image element scanning unit (15) is translatorily displaceable radially to the videodisk (12). (Fig. 1).
