Abstract
Abstract A servicing desk for an X-ray diagnosing device has functional keys for a programmed setting of operational values. The invention is particularly characterized, in that, in addition to the keys, at least one operating member is provided for a free setting of at least one operational value in a part of the servicing desk which can be covered by an adjustable cover. The cover operates switching means which, when the cover is open, switch on the operating member for free setting of the operational value at the X-ray apparatus feeding and operating the corresponding X-ray tube. The operating member is switched off when the cover is closed.
