Abstract

In a radio paging communication system, an exclusive input device such as a personal computer capable of inputting alpha-numeric code data and a normal key telephone are included for inputting message data to an alpha-numeric paging receiver. The alpha-numeric paging receiver includes a circuit for detecting a specific code in the message data. In order to input message data from the key telephone set, the specific code is input prior to input of the message data. The paging receiver displays data following the specific code as numeric code data.

Claims

1. A paging receiver comprising:

receiving means for receiving a coded signal which is transmitted from a transmitter of a base station and for demodulating the coded signal, the coded signal including address data and message data;

memory means for storing the message data demodulated by said receiving means;

standard expression memory means, detachable from said paging receiver, for storing predetermined standard expressions;

alpha-numeric display means for displaing a demodulated message data; and

display control means for reading out said message data from in said memory means and for displaying said message data on said alpha-numeric display means, said display control means including means for detecting a specific code in said message data, means for processing said message data as alpha-numeric code data until said specific code is detected by said detecting means and for processing data following said specific code as numeric code data for identifying a message to be displayed after said detecting means detects said specific code, and means for reading out a stored standard expression from said standard expression memory means by a predetermined number of numeric data following said specific code.

2. A receiver according to claim 1, wherein said standard expression memory means includes a ROM.

3. A receiver according to claim 1, wherein said standard expression memory means includes a RAM.

4. A receiver according to claim 1, further including a second standard expression memory means, built in said receiver, for storing predetermined standard expressions.

5. A receiver according to claim 1, wherein said standard expression memory means includes means for storing a pluraltiy of standard expression messages and an ID number assigned to said standard expression memory means.

6. A receiver according to claim 5, wherein said display control means comprises means for discriminating whether an ID number in the message data is coincident with the ID number assigned to said detachable memory, and means for reading out the standard expression message from said detchable memory on the basis of an abbreviation number in the message data when a coincidence is detected by said discriminating means and for displaying the ID number in the message data and the abbreviation number when a noncoincidence is detected by said discriminating means.

7. A receiver according to claim 5, wherein:

said message data includes an abbreviation number;

said display control means comprises discriminating means for discriminating whether an ID number in said message data is coincident with said ID number assigned to said standard expression memory means; and

said display control means reading out a standard expression message from said standard expression memory means when coincidence is detected by said discriminating means and displays said ID number in message data and said abbreviation number when a noncoincidence is detected by said discriminating means.

8. A receiver according to claim 7, further including a second standard expression memory means, built in said receiver, for storing predetermined standard expressions.

9. A paging receiver comprising:

receiving means for receiving a coded signal which is transmitted from a transmitter of a base statino and for demodulating the coded signal, the coded signal including address data and message data;

memory means for storing the message data demodulated by said receiving means;

standard expression memory means, detachable from said paging receiver, for storing predetermined standard expressions;

alpha-numeric display means for displaing a demodulated message data; and

display control means for reading out said message data stored in said memory means and for displaying said message data on said alpha-numeric display means, said display control means including means for detecting a specific code in said message data, and means for reading out a stored standard expression from said standard expression memory means by a predetermined number of numeric data following the specific code.

10. A receiver according to claim 9, wherein said standard expression memory means includes means for storing a plurality of standard expression messages and an ID number assigned to said standard expression memory means.

11. A receiver according to claim 10, wherein:

said message data includes an abbreviation number;

said display control means comprises discriminating means for discriminating whether an ID number in said message data is coincident with said ID number assigned to said standard expression memory means; and

said display control means read out a stored standard expression from said standard expression memory means when a coincidence is detected by said discriminating means and displays the ID number in said message data and said abbreviation number when a noncoincidence is detected by said discriminating means.

12. A receiver according to claim 9, wherein said standard expression memory means comprises a ROM.

13. A receiver according to claim 9, wherein said standard expression memory means comprises a RAM.
