Device for erasing a record carrier recorded by magnetic fields in visually readable form

摘要

The record carrier allows visually readable recordings of measured values. A measuring device associated with said record carrier is driven by a drive device. The erasing device comprises at least one erasing magnet positioned directly on top of the record carrier and movable transverse to its transport direction so that the magnetic axis is parallel to the plane of the record carrier. The movement of the erasing magnet is effective essentially in the direction of the magnetic axis. A permanent magnet is used as the erasing magnet. A carrier for the magnet is in driving connection with the driving device of the measuring device.
