Abstract
Abstract In a radio pager, when encrypting information is attached to a received message, the message is written to an encrypted message memory in distinction from an ordinary message. The message stored in the encrypted message memory is read out and displayed only when decrypting information matching the encrypting information is entered by the user of the pager. The encrypting information may be added to the received message by the user before the message is written to the encrypted message memory. With this configuration, the pager allows only the user or an authorized person to see private messages stored in the encrypted message memory.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
103 words
A radio pager comprising: receiving means for receiving a paging signal sent from a caller; storing means for storing a message included in the paging signal; first decision means for determining whether or not encrypting information for inhibiting the message from being displayed is attached to the paging signal; display means for displaying the message; and second decision means for determining whether or not the message with the encrypting information should be displayed, wherein said storing means comprises a first storage area for storing the message with the encrypting information, and a second storage area for storing the message without the encrypting information.
Claim 2
Dependent Claim
103 words
A radio pager comprising: receiving means for receiving a paging signal sent from a caller; storing means for storing a message included in the paging signal; first decision means for determining whether or not encrypting information for inhibiting the message from being displayed is attached to the paging signal; display means for displaying the message; and second decision means for determining whether or not the message with the encrypting information should be displayed, wherein said storing means comprises a first storage area for storing the message with the encrypting information, and a second storage area for storing the message without the encrypting information.
Claim 3
Dependent Claim
35 words
A radio pager as claimed in claim 1, wherein said second decision means comprises inputting means for allowing decrypting information to be input, and comparing means for comparing the decrypting information and the encrypting information.
Claim 4
Dependent Claim
28 words
A radio pager as claimed in claim 2, wherein said display means displays the message when said comparing means determines that the decrypting information matches the encrypting information.
Claim 5
Dependent Claim
90 words
A radio pager comprising: receiving means for receiving a paging signal sent from a caller; decision means for determining whether or not encrypting information is attached to a message included in the paging signal; first storing means for storing the message to which the encrypting information is not attached; second storing means for storing the message to which the encrypting information is attached; first reading means for reading the message out of said first storing means; and second reading means for reading the message out of said second storing means.
Claim 6
Dependent Claim
90 words
A radio pager comprising: receiving means for receiving a paging signal sent from a caller; decision means for determining whether or not encrypting information is attached to a message included in the paging signal; first storing means for storing the message to which the encrypting information is not attached; second storing means for storing the message to which the encrypting information is attached; first reading means for reading the message out of said first storing means; and second reading means for reading the message out of said second storing means.
Claim 7
Dependent Claim
21 words
A radio pager as claimed in claim 4, wherein said second storing means stores the encrypting information together with the message.
Claim 8
Dependent Claim
56 words
A radio pager as claimed in claim 5, wherein said second storing means comprises inputting means for allowing decrypting information matching the encrypting information to be input, and wherein when the decrypting information is input on said inputting means, said second reading means reads the message having the encrypting information out of said second storing means.
Claim 9
Dependent Claim
70 words
A radio pager comprising: receiving means for receiving a paging signal from a caller; storing means for storing a message included in the paging signal; display means for displaying the message; adding means for allowing encrypting information to be added to the message for inhibiting the message from being displayed; and decision means for determining whether or not the message to which the encrypting information is added should be displayed.
Claim 10
Dependent Claim
70 words
A radio pager comprising: receiving means for receiving a paging signal from a caller; storing means for storing a message included in the paging signal; display means for displaying the message; adding means for allowing encrypting information to be added to the message for inhibiting the message from being displayed; and decision means for determining whether or not the message to which the encrypting information is added should be displayed.
Claim 11
Dependent Claim
43 words
A radio pager as claimed in claim 7, wherein said storing means comprises a first storage for storing the message to which the encrypting information is added, and a second storage for storing the message to which the encrypting information is not added.
Claim 12
Dependent Claim
28 words
A radio pager as claimed in claim 7, wherein when the encrypting information is input while the message is displayed, the message is inhibited from being displayed afterwards.
Claim 13
Dependent Claim
44 words
A radio pager as claimed in claim 7, wherein said decision means comprises inputting means for allowing the encrypting information to be input, and comparing means for comparing the encrypting information input on said inputting means and the encrypting information added to the message.
Claim 14
Dependent Claim
26 words
A radio pager as claimed in claim 10, wherein when the encrypting information compare equal, said display means displays the message designated via said inputting means.
