ABSTRACT:
Accessories for a device used for reading a latent image recorded on an image plate by means of X-radiation. The device comprises: a drum element (8), having a concave peripheral surface (7); drive means (20) for rotating (R) the drum element at such a speed that a flexible image plate (1) located inside the drum element against the peripheral surface substantially retains the shape thereof; a light source (14) for focusing a stimulating light on the image plate (1), a light detector (17) for detecting the emitted light, as well as means (27) for moving the stimulating light and the light detector relative to the image plate in a direction (M) of said axis. The accessories comprise at least two balancing blocks (4, 5), which constitute permanent parts of the drum element and are located at a distance from the axis of rotation. The drum element can be balanced, as it is provided with image plates of varying sizes to be read, by shifting at least one balancing block (5) along a circumference (C) of the drum element to a position corresponding to the image plate.
