ABSTRACT:
A wireless unit of a selectively called wireless receiver receives a wireless signal so as to decode the received wireless signal containing a selectively calling signal having a calling number, a vector signal containing vector type information used to define a sort of a message, and a message signal containing the message. A storage unit has a plurality of storage areas, each of the storage areas is constituted by a plurality of sectors and sector sizes of the storage areas is different from each other. When the signal decoded by the wireless unit involves an own calling number, if a control unit judges that the received message is a free statement message by referring to the vector type information, then this control unit stores this message into the storage area constituted by the large size of the sector. If the control unit judges that the received message is a numeral message by referring to the vector type information, this control unit stores this message into the storage area constituted by the small size of the sector.
