Zusammenfassung:	A magnetic display erasing apparatus is provided wherein the distance by which an erasing head is moved when an unerasing operation is to be performed can be made as short as possible, thereby allowing the apparatus to be miniaturized and various designs obtained. A magnetic stripe an a magnetic display sheet are formed on a magnetic card. An erasing head is disposed on the side of the back face of the magnetic card which is conveyed. During an erasing operation, a magnetic field which is substantially parallel is formed at the position where the magnetic display sheet passes. When the magnetic display sheet is not to be erased, the erasing head is retracted from a card conveying path and then housed in a magnetic shield so as to be hermetically sealed. Accordingly, the magnetic field from the erasing head is weakened and cannot reach the magnetic display sheet.
