First Claim
Patent Images
1. A paging receiver comprising:
- first storing means for storing a paging number;
means for receiving a paging number followed by a message;
first comparing means for comparing the stored paging number and received paging number and producing a coincidence signal when they are identical;
means responsive to said coincidence signal for receiving said message;
means for displaying the received message;
second storing means for storing a first identification number;
third storing means for storing a second identification number;
means for reading said second identification number out of said third storing means;
means for comparing said first identification number and the read-out second identification number; and
means for preventing said displaying means from displaying said message if said first and second identification numbers are not identical.

Abstract
A paging receiver comprises an ID memory storing an ID number assigned to the receiver. If the ID number stored in the ID memory is coincident with an ID number stored in an ID card which is to be attached to the receiver, a received or stored message is displayed. If they are not coincident with each other, the received or stored message is prevented from being displayed. Thus, unauthorized access to the message can be prevented.

5. A paging receiver comprising:
-
power switch means for turning on and off said receiver; receiver means for receiving and demodulating a paging signal including a paging number and a message following said paging number to produce a demodulated paging number and message; paging number storing means for storing a paging number; paging number detector means for comparing said demodulated paging number with the stored paging number and producing a coincidence signal when they are identical with each other; message memory means responsive to said coincidence signal for storing said demodulated message; back-up battery means for supplying power to said message memory means irrespective of the condition of said power switch means; ID memory means for storing a first ID number; ID card means for storing a second ID number; ID reader means for reading said second ID number from said ID card means; ID comparator means for comparing said first ID number and said second ID number and producing a non-coincidence signal if they are not coincident with each other; display means for displaying the demodulated or stored message thereon; and means responsive to said non-coincidence signal for preventing said display means from displaying said message thereon. - View Dependent Claims (6, 7)

8. A receiver comprising:
-
paging number memory means for storing a paging number; means for receiving a paging number followed by a message; paging number comparator means for comparing the stored paging number and received paging number and producing a coincidence signal when they are identical; means responsive to said coincidence signal for receiving said message; display mans for displaying the received message; ID memory means for storing a first ID number; ID card means for storing a second ID number; ID reader means for reading said second ID number from said ID card; ID comparator means for comparing said first ID and read-out ID numbers and producing a non-coincidence signal when said ID numbers are not identical with each other; and means responsive to said non-coincidence signal for preventing said display means from displaying said message. - View Dependent Claims (9, 10, 11, 12, 13)

14. A radio paging receiver having a display function, comprising:
-
receiving means for receiving a first signal indicative of a paging number and a subsequent message information signal; first detection means for detecting said first signal among outputs of said receiving means with its own paging number and outputting a first coincidence detection signal when a coincidence therebetween is detected; first means responsive to said coincidence detection signal for receiving and processing said message information signal and for memorizing or displaying said message information signal; second detection means for detecting an ID number coded on an ID card with its own ID number and outputting a non-coincidence detection signal when these ID numbers are not coincident; and second means responsive to said non-coincidence detection signal for prohibiting said display.

15. A paging receiver comprising:
-
means for detecting a paging number meant for said receiver; message memory means for storing a message following said paging number; means for generating a message read-out signal; means responsive to said message read-out signal for checking if a message is stored in said message memory; means for displaying a first pattern if no message is stored in said message memory; means for reading a message out of said message memory if a message is stored in said message memory; ID source means for producing an ID number assigned to said receiver; mean responsive to the output of said ID source means for detecting said ID number; means for displaying a second pattern in response to no detection of said ID number; and means for displaying the read-out message in response to the detection of said ID number. - View Dependent Claims (16, 17)

18. A method of controlling display of a paging receiver, comprising the following steps of:
-
storing a paging number; receiving a paging number followed by a message; comparing the stored paging number and the received paging number and producing a coincidence signal when they are identical; responsive to said coincidence signal, receiving said message; displaying the received message; storing a first identification number; storing a second identification number; reading out the stored second identification number; comparing said first identification number and said read-out second identification number; and preventing said step of displaying the received message if said first and second identification numbers are not identical. - View Dependent Claims (19, 20, 21)

22. A method of controlling display of a paging receiver, comprising the following steps of:
-
detecting a paging number meant for said receiver; storing a message following said paging number; generating a message read-out signal; responsive to said message read-out signal checking if a message is stored; reading out the stored message if a message is stored; detecting an ID number assigned to said receiver; displaying the read-out message in response to the detection of said ID number; and prohibiting the display of the read-out message in response to no detection of said ID number. - View Dependent Claims (23, 24)

25. A receiver comprising:
-
means for storing a paging number; means for receiving a paging number followed by a message; means for comparing the stored and received paging numbers and producing a coincidence signal when they are identical; means responsive to said coincidence signal for receiving said message; means for storing the received message; display means for displaying the stored message; ID source means for producing an ID number assigned to said receiver; means responsive to the output of said ID source means for detecting said ID number; and means responsive to no detection of said ID number for prohibiting said display means from displaying the stored message. - View Dependent Claims (26)
