Abstract

A radio pager capable of displaying a message implemented as a fixed sentence includes a radio section for receiving and demodulating a paging signal. A first storage stores a plurality of address numbers allocated to the pager, and a comparing section compares an address number included in the demodulated paging signal with each of the address numbers stored in the first storage, and outputs, if the address number included in the demodulated paging signal is identical with any of the address numbers stored in the first storage, the address number included in the demodulated paging signal as an address number assigned to the pager while writing message data following the address number in a message memory. A second storage stores a plurality of tables each listing a particular kind of fixed sentences. A third storage stores correspondence between the address numbers allocated to the pager and the tables. A message processing section selects, based on the stored correspondence, one of the tables corresponding to the address number assigned to the pager, and selects one of the fixed sentences corresponding to the message data written to the message memory on the basis of stored correspondence. A display section displays the fixed sentence selected.

Claims

1. A radio pager capable of displaying a fixed sentence, comprising:

a radio section for receiving and demodulating a paging signal;

a first storage for storing a plurality of address numbers allocated to said radio pager;

a comparing section for comparing an address number included in the paging signal demodulated by said radio section with each of the plurality of address numbers stored in said first storage, and for outputting, if said address number of said paging signal matches any one of said plurality of address numbers, said address number while writing message data following said address number in a message memory;

a second storage for storing a plurality of tables each listing a particular kind of fixed sentences;

a third storage, accessed by said address number, for storing a leading address data for each of said plurality of tables;

a message processing section for selecting, based on said leading address data stored in said third storage, one of said plurality of tables corresponding to said address number, and for selecting one of said fixed sentences corresponding to the message data written to said message memory; and

a display section for displaying the fixed sentence selected by said message processing section.

2. A radio pager as claimed in claim 1, wherein said message processing section, said second storage, and a driver included in said display section for driving a display are configured as a single chip.

3. A radio pager as claimed in claim 1, wherein said first storage and said third storage comprise a single electrically erasable programmable read-only memory (EEPROM).

4. A radio pager as claimed in claim 3, wherein said second storage comprises a single read-only memory (ROM).

5. A radio pager as claimed in claim 4, wherein said message processing section comprises a micro processing unit (MPU), a decoder, and a random access memory (RAM).

6. A radio pager as claimed in claim 1, wherein contents for being displayed by said display section are limited in advance based on said address number assigned to said radio pager and with said second storage dealt with as a unit.

7. A radio pager as claimed in claim 6, further comprising means for limiting the contents in advance, said means for limiting including a fixed sentence data area included in said second storage.

8. A radio pager comprising:

a radio section for receiving and demodulating a paging signal;

address number storage means for storing a plurality of address numbers allocated to said radio pager;

a match detecting section for comparing a demodulated address number included in the demodulated paging signal with the plurality of address numbers stored in said address number storage means, said match detection section for outputting, when the demodulated address number matches any one of the plurality of address numbers, said demodulated address number as an address number assigned to said radio pager while writing message data following said address number in a message memory;

fixed sentence storage means for storing a fixed sentence selected on the basis of the message data written to said message memory;

wherein said fixed sentence storage stores a plurality of tables each listing a particular kind of fixed sentences;

fixed sentence information storage for storing correspondence between the plurality of address numbers allocated to said radio pager and said plurality of tables; and

a message processing section for selecting, based on said correspondence stored in said fixed sentence information storage, one of said plurality of tables corresponding to said address number assigned to said radio pager, and selecting one of said fixed sentences corresponding to the message data written to said message memory, and outputting the one fixed sentence to said display section.

9. A radio pager as claimed in claim 8, wherein said message processing section, said fixed sentence information storage, and a display driver included in said display section are included in a single chip.
