PROBLEM TO BE SOLVED: To reliably preserve affixed information required for users in such conditions that the user cannot immediately perform a preservation operation, for example, during driving of a vehicle. SOLUTION: A receiver receives a digital radio broadcasting in which affixed information is multiplexed to speech information, and is provided with a memory for recording the received affixed information and a display for displaying the affixed information recorded in the memory. A user displays the affixed information recorded in the memory on a display to designate the affixed information to be preserved, thereby conducting a preservation operation of the affixed information. In recording the received affixed information in the memory, a control unit of the receiver determines whether or not the memory is full. If not full, the control unit records the received affixed information in the memory as up-to-date affixed information. If the memory is full, the control unit erases the oldest affixed information among the affixed informations under the unpreserved operation, from the memory, and then it records the received affixed information as the up-to-date affixed information.
