Device for reading out X-ray information stored in storage phosphor plates, comprising - an input unit, in which multiple cassettes (14, 28, 32), each accommodating a storage phosphor plate to be read out, can be input, wherein the input unit comprises an oblong take-up slot for taking up one of the cassettes (14, 28, 32) which were input into the input unit and comprises a first inclined plane which is adjacent to the upper end of the take-up slot and which slopes up towards the front side of the input unit, from which an operator can input cassettes (14, 28, 32), so that a cassette which is located on the inclined plane can slide into the take-up slot by gravity and can position itself at a lower support surface which is provided at the bottom end of the take-up slot in a lowered position with respect to the second inclined plane, - a read-out unit, which is located below the input unit and in which storage phosphor plates can be read out, wherein a storage phosphor plate can be removed from a cassette (14, 28, 32) which is located in the take-up slot of the input unit, can be guided to the read-out unit which is located below the input unit in order to read out the storage phosphor plate and, after completion of the reading out of the storage phosphor plate, can be returned into the cassette (14, 28, 32) which is located in the take-up slot of the input unit, - an output unit, which is adjacent to the input unit and in which cassettes (14, 28, 32) can be output, wherein the output unit comprises a support surface which is arranged aligned with the lower support surface of the take-up slot, and - a shifting means for shifting the cassette which is located in the take-up slot of the input unit after having read out the storage phosphor plate, which is located in said cassette, in the read-out unit which is located below the input unit, along a substantially horizontal shifting path towards the output unit which is adjacent to the input unit, so that the cassette which is resting on the lower support surface of the take-up slot is shifted along the lower support surface of the take-up slot onto the support surface of the output unit which is arranged aligned with the lower support surface of the take-up slot, wherein the shifting means comprises a horizontally movable conveyor belt, at which two drivers (58, 60) are provided for carrying away the cassette taken up by the take-up slot, wherein the two drivers (58, 60) are spaced apart, along the length of the conveyor belt, by a distance which is greater than the greatest width of the horizontal widths of the multiple cassettes (14, 28, 32). -
