Title: Electronic pocket notebook-type pager
Inventor: KUDOH KAZUHIRO
IPC: G08B5/22
Filed: 1991-11-29
Granted: 1996-09-24
Abstract: A display-equipped radio pager according to the present invention provides a detecting circuit 6 to detect keywords which are distinguished by a specific mark such as double quotation marks for each message received, and another detecting circuit to detect whether the received keyword is already registered in the memory or not.  The pager also provides a registering circuit to automatically register the received data related to the keyword  into the memory.  When a signal including its own call number is received, a call alert is issued, and a display means 8 displays a message included within that signal on a display 9.  In addition, when a keyword is detected, the detecting circuit 14 detects whether the received keyword within that message is already regis-tered in the memory or not and, if the same keyword is detected, a registering circuit 15 then registers the data related to the keyword within the message into the memory 10 as additional data.  When a personal name is registered in the memory 10 as a keyword and the corre-sponding address is registered as data of the keyword, this stored information is treated as a part of the record of an electronic pocket notebook and, when a user wishes to read out the contents of the memory 10 by keying in a keyword from the keyboard 13, the LCD driver 8 reads out the information registered in the memory 10 and displays it on the LCD 9.
