Abstract

An apparatus for reading out storage phosphor plates (2) for storing X-ray information with one or more rotating conveyance rolls (11 to 14) for conveying the storage phosphor plate (2), an alignment edge (19, 22) to which the storage phosphor plate (2) can be aligned, and a read-out device for reading out the X-ray information stored in the storage phosphor plate (2). For more reliable alignment of the storage phosphor plate (2), in particular also with a storage phosphor plate (2) orientated substantially horizontally, provision is made such that the storage phosphor plate (2) is conveyed by the rotating conveyance rolls (11, 12) in direction (R, R′) towards the alignment edge (19, 22) and a control device is provided for setting a pressure with which the conveyance rolls (11, 12) press onto the storage phosphor plate (2), the pressure being set such that a slack or slippage occurs between the rotating conveyance rolls (11, 12) and the storage phosphor plate (2) being conveyed when the storage phosphor plate (2) comes into contact with the alignment edge (19, 22), by means of which the storage phosphor plate (2) can change its orientation and thus be aligned to the alignment edge…
