The invention relates to an image plate readout device, the readout device comprising receiver elements for the reception of an image plate and/or a transfer element intended for an image plate. In connection with the readout device is provided, for detecting an object, at least one sensing element, which is in turn set in data communication with the readout device in such a way that, upon detecting an object, the sensing element delivers a signal to the readout device. In response to being triggered by a signal delivered by the sensing element, the readout device executes some function.
