Selective call radio apparatus with improved display function

1. A method of displaying messages in a selective call radio apparatus comprising the steps of:

displaying stored messages, which are already received, on a display unit in a first display attribute in a message display mode in response to a display instruction;

when a new message is received during the display of said stored messages,

temporarily stopping the display of said stored messages on said display

unit in said message display mode;

displaying said new message on said display unit in a second display attribute different from said first display attribute,

said step of displaying stored messages includes displaying said stored messages on said display unit in an order in said first display attribute in said message display mode,

said stored messages including a message being read immediately before receipt of said new message,

stopping the display of said new message in response to a display continuation instruction;

displaying remaining ones of said stored messages in the order in said first display attribute in said message display mode, after stopping of the display of said new messages, and

restoring said message being read immediately before receipt of said new message.

2. A method according to claim 1 , wherein said second display attribute is a color inversion.

3. A method according to claim 1 , wherein said second display attribute is a highlighted display.

4. A method according to claim 1 , wherein the order is an order of reception of said stored messages.

5. A method according to claim 4 , further comprising the step of:

receiving messages;

sequentially storing said received messages in a memory in the order of reception of said messages, and

wherein said step of displaying stored messages includes sequentially reading out said messages from said memory in the order of reception of said messages.

6. A method according to claim 1 , further comprising the step of:

receiving each of said messages;

storing the received messages in a memory together with a reception time, and

wherein said step of displaying stored messages includes sequentially reading out said messages from said memory based on the reception times of said messages.

7. A method according to claim 6 , wherein said step of displaying stored messages includes sequentially reading out said stored messages from said memory based on the reception times of said messages and a reference time, and

wherein said method further comprises the step of:

designating said reference time.

8. A method according to claim 7 , wherein said reading out step includes:

comparing said reference time and the reception time of each of said stored messages; and

sequentially reading ones of said messages previous to said reference time.

9. A selective call radio apparatus comprising:

a display unit;

a storage unit for storing messages;

an operation unit used to input instructions and data;

a message receiving unit; and

a control unit for reading out said stored messages from said storage unit to display on said display unit in a first display attribute in a message display mode in response to a display instruction supplied from said operation unit, for displaying a new message on said display unit in a second display attribute different from said first display attribute when said new message is received by said message receiving unit during the display of said messages,

said control unit displays said stored messages on said display unit in an order of reception of said stored messages in said first display attribute in said message display mode,

said stored messages including a message being read immediately before receipt of said new message,

said control unit displays remaining ones of said stored messages in the order of reception in said first display attribute, in response to a display continuation instruction supplied from said operation unit, and

said control unit restores said message being read immediately before receipt of said new message.

10. A selective call radio apparatus according to claim 9 , wherein said second display attribute is a color inversion.

11. A selective call radio apparatus according to claim 9 , wherein said second display attribute is a highlighted display.

12. A selective call radio apparatus according to claim 9 , wherein said control unit sequentially stores the messages received by said message receiving unit in said storage unit in the order of reception of said messages.

13. A selective call radio apparatus according to claim 12 , wherein said control unit includes a read pointer and a write pointer, and stores the message received by said message receiving unit in said storage unit using said write pointer and sequentially reads said stored messages from said storage unit using said read pointer.

14. A selective call radio apparatus according to claim 9 , wherein said control unit includes a timer and a reference time register for holding a reference time, and

wherein said control unit stores the message received by said message receiving unit in said storage unit together with a reception time from said timer,

and sequentially reads out said stored messages from said storage unit based on the reception times of said messages and said reference time.

15. A selective call radio apparatus according to claim 14 , wherein said control unit sets said reference time in said reference time register when said reference time is supplied from said operation unit.

16. A selective call radio apparatus according to claim 14 , wherein said control unit sequentially reads said stored messages previous to said reference time from said storage unit.
