Abstract

PURPOSE:To obtain easy to see display of a date time stamp and a time stamp in the personal selective calling receiver with a display device. CONSTITUTION:Display segments used to display a time of reception and display segments used to display a date of reception are used in common in an LCD, and the segments for those are used for respective display as time elapses. Segments used to display a reception message Number and an address Number or the like, and segments used to display the date and the time of reception are used in common and they are displayed selectively as time elapses.

Description

Detailed Description of the Invention

[0001]

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

2. Description of the Related Art FIG. 5 is a block diagram of a conventional general individual selective call receiver with display. The signal received by the wireless unit 2 via the antenna 1 and demodulated by the detection / waveform shaping unit 3 is processed by the decoder 4. ID-RO here
The information (own ID, address of each ID) stored in M6 is sent to the decoder 4 through the CPU 5 in advance. The decoder 4 receives the signal-processed received signal and its own I
The received message information following the self ID, the address No. of the self ID only when both are matched. 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, displays a necessary message on the LCD display 7, and causes the speaker of the sound notification unit 8 to sound through the decoder 4, and further drives the LED. Further, in a receiver having a vibration notification motor (vibrator) function, the vibrator is driven.

Received message received, address N
o. The reception time information can be received in a RAM in the CPU 5 with a message reception order (message No.) in the order of reception, taken out from the RAM if necessary, and displayed on the LCD 7. When the reading switch 9 interrupts the reading of the CPU 5, the messages are sequentially fetched from 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 sound alert unit 8 during 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 received message. Then, after an arbitrary fixed time (after t seconds) within the automatic deletion time of the display after the interruption is taken, the message No. , Address N
o. Changes to the time stamp display. Furthermore,
Then, by performing a switch operation, the received message can be changed to the display of the date stamp.

[0005]

In such a conventional receiver, when the date stamp is displayed, it cannot be displayed at the same time as the received message. Therefore, the user operates the switch to switch between the received message and the date. There is a problem that the operation is troublesome because it is necessary to switch between the attached time stamp and the time stamp. In this case, if the LCD is configured so that the date stamp is displayed 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, which makes the display difficult for the user to see. There's a problem. An object of the present invention is to provide an individual selective calling receiver with a display in which the display of the date stamp and the time stamp is made easy to see.

[0006]

The receiver of the present invention is an LC
In D, the display segment for displaying the reception time and the display segment for displaying the reception date are shared, and these are switched and displayed as time passes.
In addition, the received message No. And address No. It is configured such that the segment for displaying etc. is also used as the segment for displaying the reception date and the reception time, and these are switched and displayed over time.

[0007]

By displaying the reception date and the reception time in the same segment with the passage of time, the date and the time can be displayed without a switch operation, and it is not necessary to provide each segment individually.

DESCRIPTION OF THE PREFERRED EMBODIMENTS 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,
6 is a block diagram showing an internal configuration of a CPU of the receiver shown in FIG. 5. FIG. Reference numeral 11 is a timer circuit for counting the task interval of the CPU 5, 12 is an arithmetic circuit, and 13 is a built-in RAM. Reference numeral 14 is a program counter for controlling the progress of the program in the program ROM 15, 16 is a decode & 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 generation unit that converts display data into a display waveform of the LCD 4. 20 is a message read switch, 2
Reference numeral 1 is a common bus line between the respective units 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, on the LCD 7, as shown in FIG. , Address No. In order to display, the segment is also used as the segment for displaying the date stamp and the time stamp, and by electrically switching between them, the segments are switched and displayed. However, in this case, some of the segments, for example, the segment for displaying “month”, “day”, etc., can be configured as a dedicated segment for date.

The "LCD display operation upon reception" in this configuration will be described with reference to the LCD display screen of FIG. 1 and the flow chart shown in FIG. Own ID from decoder 4
Received message information subsequent to the self 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 the already stored message information,
Latest message No. Is attached. In addition, a message and a message No. , Address No. Display data is sent to the display data latch memory 18 and the display data is latched. Thereafter, the display data cannot be rewritten unless new data is input to the display data latch memory 18 or the display unit is reset.

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

Next, "LCD during message reading
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
When an interrupt is issued from 0, one of the messages stored in the RAM 13 is displayed data latch memory 18
Taken out. In this case as well, the message, the message No. , Address No. Is RAM
It is taken out from 13 and displayed on the LCD 7, and the timer circuit 1
The message and the date / time stamp are displayed on the LCD 7 when t1 seconds have passed at 1 and the message and the time stamp are displayed on the LCD 7 when t2 seconds have passed.

[0013]

As described above, according to the present invention, each display segment of the reception date time stamp and the reception time time stamp is used in common, and these segments are displayed with a temporal shift, so that the user operates the switch. The necessary information can be viewed in sequence without needing to do so, the amount of information that the user must see at one time can be reduced, the number of LCD display control lines can be reduced, and the size of the display segment can be prevented from becoming smaller. Easy display can be performed.
