DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an individually selected paging receiver with a display, and more particularly to an individual selection with a display capable of displaying date information and time information of a received message when reading a message such as a reception interrupt or a read interruption. It relates to a call receiver.

[0002]

2. Description of the Related Art FIG. 5 is a block diagram of a conventional general individually selected paging receiver with display. A signal received by the radio unit 2 via the antenna 1 and demodulated by the detection / waveform shaping unit 3 is subjected to signal processing by the decoder 4. Where ID-RO
The information (self ID, address of each ID) stored in M6 is sent to the decoder 4 in advance through the CPU 5. In the decoder 4, the signal-processed received signal and its own I
D, the received message information following the own ID and the address No. of the own ID only when both match. To C
Send to PU5. At the same time, the received date information and time information are sent from the decoder 4 to the CPU 5. CPU5
Receives a reception interrupt from the decoder 4, causes the LCD display 7 to display a necessary message, makes the speaker of the sound notification unit 8 sound through the decoder 4, and further drives the LED. In a receiver having a motor (vibrator) function for vibration notification, the vibrator is driven.

The received message received, address N
o. The reception time information can be stored in the RAM inside the CPU 5 with the message reception order (message No.) added in the reception order, and the information can be taken out from the RAM as needed, and displayed on the LCD 7. When a read interrupt is applied to the CPU 5 by the read switch 9, messages are sequentially taken out of the RAM in the CPU 5 and displayed on the LCD 7. If the received message is an unread message (unconfirmed message), a drive signal is output to the ringing sound notification unit 8 at the time of reading.

FIG. 6 shows the LC of the received message of this receiver.
An example of D display is shown. When there is a reception interrupt or a read interrupt, first, the message No. , Address No. , Display the received message. After a predetermined time (after t seconds) within the automatic display erasing time after the interruption, the message No. , Address N
o. Changes to the time stamp display. Furthermore,
By performing a switch operation thereon, the received message can be changed to a display of a date and time stamp.

[0005]

In such a conventional receiver, when a date and time stamp is displayed, it cannot be displayed at the same time as a received message. There is a problem that the operation has to be troublesome because it is necessary to switch between the attached time stamps. In this case, if the LCD is configured to display the date and time stamp separately from the received message, the number of display control lines of the LCD is increased, and each display on the display screen is reduced, making the display difficult for the user to see. There's a problem. SUMMARY OF THE INVENTION It is an object of the present invention to provide an individual selective call receiver with a display that makes it easy to see the display of a date time stamp and a time time stamp.

[0006]

The receiver of the present invention comprises an LC
In D, a display segment for displaying the reception time and a display segment for displaying the reception date are also used, and these are switched and displayed as time elapses.
The received message No. And address No. , Etc., and a segment for displaying the reception date and reception time, which are switched and displayed as time elapses.

[0007]

By displaying the reception date and the reception time in the same segment as time elapses, the date and the time can be displayed without operating the switch, and there is no need to provide each segment separately.

[0008]

Next, the present invention will be described with reference to the drawings. FIG. 2 is a diagram showing an embodiment of the receiver of the present invention.
FIG. 6 is a block diagram showing an internal configuration of a CPU of the receiver shown in FIG. Reference numeral 11 denotes a timer circuit for counting the task interval of the CPU 5, reference numeral 12 denotes an arithmetic circuit, and reference numeral 13 denotes a built-in RAM. 14 is a program counter for controlling the progress of the program in the program ROM 15, 16 is a decode and control unit for controlling each unit according to the contents of the program ROM 15, and 17 is a clock supply circuit for supplying a clock for operating the CPU. Further, 18 is a memory for latching display data, 19
Is a display waveform generator for converting display data into a display waveform of the LCD 4. 20 is a message reading switch, 2
Reference numeral 1 denotes a common bus line between each unit in the CPU 5. still,
The decoder 4 has a decoder function part 41 having a function of decoding a reception ID and a reception message, and a clock 42 for supplying a time stamp.

Further, in the LCD 7, as shown in FIG. , Address No. Is displayed, the segment is also used as a segment for displaying the date time stamp and the time time stamp. By electrically switching these segments, each segment is switched and displayed. However, in this case, some segments, for example, a segment for displaying “month”, “day”, etc., can be configured as a dedicated segment for date.

The "LCD display operation at reception" in this configuration will be described with reference to the LCD display screen of FIG. 1 and the flowchart shown in FIG. Own ID from decoder 4
Received message information following its own address No. The received date / time information is interrupted by the CPU 5 and stored in a specific bank of the RAM 13. At this time, it is distinguished from already stored message information,
The latest message No. Is attached. In addition, message, message No. , Address No. Is sent to the display data latch memory 18, and the display data is latched. Thereafter, the display data is not rewritten unless new data is input to the display data latch memory 18 or the display unit is reset.

The timer circuit 11 counts the time since the display processing. After an elapse of t1 seconds, an interrupt is input to the bus line 21, and the message from the RAM 13 to the display data latch memory 18 is displayed. The display data of the stamp is sent, and the display on the LCD 7 is rewritten. Further, after elapse of t2 seconds, an interrupt input is applied again to the bus line 21, a message and display data of the time stamp are sent from the RAM 13 to the display data latch memory 18, and the display on the LCD 7 is rewritten.

Next, "LCD for reading message"
The "display operation" will be described with reference to the LCD display screen of FIG. 1 and the flowchart of FIG. Message read switch 2
0, one of the messages stored from the RAM 13 is stored in the display data latch memory 18.
Is taken out. In this case as well, the message, message No. , Address No. Is RAM
13 and is displayed on the LCD 7 and the timer circuit 1
At t1, the message and the time stamp are displayed on the LCD 7 when t1 seconds have elapsed, and the message and time stamp are displayed on the LCD 7 when t2 seconds have elapsed.

[0013]

As described above, according to the present invention, the display segments of the reception date time stamp and the reception time time stamp are also used, and these are displayed in a time-shifted manner. At a minimum, the required information can be viewed in order, and the amount of information that must be viewed at a time for the user can be reduced, the number of LCD display control lines can be reduced, and the display segments can be prevented from being downsized. Easy display can be performed.
