ABSTRACT:
Message data are picked up by using a decoder2from received signals received by a receiver portion1of a radio paging receiver, and stored in a RAM4aof a CPU4. An informing portion9informs a user of the message. The user designates any character sequences in the message stored in the RAM4aby a character sequence designating unit4b. A character sequence retrieving unit4cretrieves whether or not designated character sequences are contained in stored messages. When the messages containing the designated character sequences are detected, a time counting unit4dmonitors whether or not a predetermined time has been lapsed after storage of concerned messages. An erasing unit4eerases unnecessary messages stored in the RAM4afrom the RAM4aafter the predetermined time has been lapsed. Accordingly, the messages which are transmitted periodically and repeatedly to the radio paging receiver can be erased collectively and automatically and thus complicatedness in erasing the messages can be eliminated and also operability can be enhanced.
