Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a paging receiver with a display function for receiving and displaying a message as well as a wireless call.

[Prior art and its problems]

Conventionally, each time a message is received, the received message and its reception time (hours and minutes) are stored in order, and when the reception message is read out and displayed by a switch operation, the reception time is also displayed. Paging receivers are commonly known.

Such a display of the reception time is convenient for the receiver's wearer, but a paging receiver that can store and retain a received message for a long period of time displays not only the reception time but also the reception date (month, day). ) Is also stored, and it is desirable to be able to display the reception date when the received message is read out and displayed by the switch operation.

However, in the configuration in which the reception date and the reception date as well as the reception time are displayed at the same time as the reception message, there is a problem that the display device must be upsized or the displayed characters must be miniaturized. There is also the problem of complication.

[Purpose of device]

The present invention has been made in view of the above conventional problems, and an object thereof is to provide a paging receiver with a display function capable of effectively displaying a reception message and the reception date and time thereof even on a small display device. To provide.

[Key points of device]

In order to achieve the above-mentioned object, the present invention, when displaying a received message that has already been stored, displays the received time together with the message if the received message is the message received on the current day, and displays the received message other than the message received on the current day. For example, it is characterized in that the reception date is displayed together with the message.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the circuit configuration of an embodiment of the paging receiver of the present invention.

In the figure, an antenna 1 is an antenna that receives a radio signal transmitted from a base station, and the received signal is sent to a receiving unit 2. The receiving unit 2 is a circuit that detects, amplifies, and demodulates the received signal into serial digital data composed of “0” and “1”, and this digital data is given to the decoder unit 4. On the other hand, the ID-ROM 3 is a fixed memory that stores, for example, two types of address numbers as its own calling numbers. The decoder unit 4 includes the receiving unit 2
A circuit that determines whether the call number included in the received data matches the call number stored in ID-ROM3 after synchronizing the input data of the received data output from the device and performing error correction. is there. Here, when the calling numbers match, a reception interrupt signal is output to the CPU 7, and the message information received subsequently to the calling number is converted to parallel data and output to the CPU 7, while the calling numbers match. If not, the reception unit 2 gives an instruction to stop the reception.

The key input unit 5 is composed of various key switches for operating the receiver. For example, a read switch SW ₁ for reading message information stored in a memory 8 described later one by one and sequentially displaying the message information, You can switch the upper and lower digits of the currently displayed message to display,
Changeover switch SW ₂ for switching and displaying the reception time (hour, minute) and the reception date (month, day), and also to stop the alarm sound at the time of data reception or to stop the message display and display the time. It includes a reset switch SW ₃ etc. for switching to. The clock unit 6 divides the clock signal sent from the CPU 7 and divides it by a predetermined period (for example, 1
It is a circuit that outputs a clock signal of (seconds).

The CPU 7 performs time counting processing based on the time counting signal from the clock section 6, performs reception interrupt processing based on the reception interrupt signal from the decoder section 4, or the key input section 5
It is a central processing unit that performs various key processes based on a key input signal from the. The specific processing will be described later with reference to FIG. The memory 8 is a memory that mainly stores or reads out various data such as message information output from the decoder unit 4 in accordance with an instruction from the CPU 7. The detailed configuration is as follows.
It will be described later with reference to FIG.

The display buffer 9 is a memory that temporarily stores the display data sent from the CPU 7. Display driver 10

This is a circuit for causing the LED 15 to emit light in a pattern corresponding to the call type information at the same time when the speaker 13 is driven by 2.

Next, FIG. 2 is a schematic configuration diagram showing the main contents of the memory 8.

In the figure, a buffer register X is a register for temporarily storing various newly received information. The clock register Y is a register for storing current date and time information including month, date, hour, minute, etc., which is obtained by the CPU 7 sequentially measuring the clock signal output from the clock unit 6. The reception data register Z is composed of a plurality of storage areas Z ₁ , Z ₂ , Z _3, ... And the like, and is a register for storing the received information in that storage area in order from the newest one. Then, each storage area Z ₁ , Z
₂ , Z ₃ ... etc. are all call type storage section D ₁ for storing call type information for identifying a calling party, message storage section D ₂ for storing message information, and reception date information. Reception date storage unit D ₃ for storing (month, day) and reception time storage unit D ₄ for storing reception time information (hour, minute)
It consists of

In addition, the display pointer P is selected from the data stored in the respective storage areas of the reception data register Z from the display unit 11
It is a pointer that designates one piece of data to be displayed on. The message number register N is a register for storing the number of message information stored in the reception data register Z. The display flag F is a flag that enables display of a received message when this is set.
The alarm flag G is a flag that enables notification by the speaker 13 and the LED 15 when new information is received when this is set. The timer register T is
It is a register used for time measurement for driving the speaker 13 and the LED 15 for a predetermined time when new information is received, or for displaying a received message for a predetermined time.

Next, the main processing operation of this embodiment will be described with reference to FIGS. 3 and 4. Note that FIG. 3 is a flowchart showing the overall processing operation of this embodiment, and FIG. 4 is a diagram showing changes in the display state of the display unit 11 according to the operation of the switches SW ₁ and SW ₂ .

First, in FIG. 3, it is normally in a HALT state (step a ₀ ), and when a reception interrupt signal is sent from the decoder section 4 shown in FIG. 1, it is included in the reception data. The call type information and the message information and the reception date and time (date and time) information, which is the contents of the clock register Y when the call is received, are temporarily stored in the buffer register X of the memory 8 (step a ₁ ). After that, it is judged whether or not these received data are repeat calls sent repeatedly twice or more (step a ₂ ), and only when they are not repeat calls, the process proceeds to the next storing process (step a ₃ ).
In this storage processing, all the data already stored in the reception data register Z is shifted down by one step, and the storage sections D ₁ , D ₂ , D ₃ , D of the head storage area Z ₁ which has become empty by this are shifted.
_The information stored in the buffer register X is stored in ₄ , respectively.

Then, it is judged whether or not the content of the message number register N is the maximum value (step a ₄ ), and if it is already the maximum value, N is left as it is, and if it is not the maximum value yet, N is incremented by 1 (step a ₄ ). ₅ ). Then, to start the display processing sets the display flag F (step a _6). In this display processing, the new received data is displayed on the display unit 11 by the display driver 10 via the display buffer 9 shown in FIG. Then, to start the notification process sets the alarm flag G (step a _7). In this notification processing, a command is given to the speaker driver 12 and the LED driver 14 shown in FIG. 1, and the speaker 13 and the LED 15 are driven in a pattern corresponding to the call type information. Thereafter, the contents of the timer register T to "0" (Step a _8).

On the other hand, in the halt state (step a ₀ ), when a time-measurement signal at 1-second intervals is output, normal time-measurement processing is first performed (step a ₉ ). In this time counting process, the time counting signal is counted using the time counting register Y to obtain the current time data including month, day, hour, minute and the like. Next, whether the display flag F is set, i.e., to determine whether during the display of the message (Step a _10). If F is set, incremented by one timer register T (step a _11), whether the contents of the T has become "8", i.e., determines whether the elapsed 8 seconds (step a ₁₂₎ . T = If "8", the alarm flag if G is set, i.e., to determine whether during the notification process at the time of data reception (see step a ₇₎ (step
a ₁₃ ), If G is set, G is reset and notification is stopped (step a ₁₄ ). From this, when new data is received, unless a reset switch SW ₃ described later is operated (see steps d _{1 to} d ₃ ), 8
Only the second is notified by the speaker 13 and the LED 15.

Subsequently, whether the contents of the timer register T has become "30", i.e. to determine whether 30 seconds have elapsed (step a _15), T = if "30", and reset the display flag F ( step a _16), switching from the message displayed on the normal time display (step a _17). From this,
When new data is received, or when the data stored in the memory 8 is read out by the switch SW ₁ or SW ₂ and displayed, the reset switch SW ₃ described later is not operated (steps d ₄ , d ₅ ), 3 on the display 11
Data is displayed only for 0 seconds, and after 30 seconds have passed, the time is switched to normal time display.

Further, in the halt state of step a ₀ , if any key switch is operated and a key input signal is sent, it is _first determined whether or not the switch is the read switch SW ₁ (step b ₁ ). If it is the read switch SW ₁ , it is determined whether the display flag F is set, that is, whether the message is being displayed (step b ₂ ). Here, if no F is set, whether the message number register N is "0", i.e., to determine whether or not at all stored in the received message is the receive data register Z (Step b _3), if N = "0" else sets the display flag F (step b _4), followed by setting "1" on the display pointer P and have been stored in the first storage area Z ₁ of the received data register Z specifying the data (step b _5). On the other hand, if it is set display flag F in step b _2, that is, if during the display of a message, the display pointer P 1
One by counting up, specify the following data in the received data register Z (Step b _6). The contents of the display pointer P, it is determined whether or exceeds the content of the message number register N (Step b _7), the flow advances to step b ₈ if not exceeded.

In step b _8, the reception date of the data designated by the display pointer P (in the storage to the reception date memory unit D ₃₎ Whether equal to the current date stored in the time register Y, i.e. specification data to determine whether the day received data (step b _8). Here, if the data received on the day, since the date is not particularly necessary for the day (hour, minute) the reception time with the message is displayed (step b _9).
On the other hand, if the data received on the day, since it is required towards the reception date than its reception time, and displays the received date (month, day) together with the message (Step b _10). Thereafter, (step b ₁₁₎ by setting "0" in the timer register T, starts a timer operation for 30 seconds as described above (see step _{a 10, a 11, a 15} , a 16).

On the other hand, in step b _7, when the contents of the display pointer P exceeds the contents of the message number register N stops message display by resetting the display flag F, switched instead normal time display ( Step b ₁₂ ).

When it is determined in step b ₁ that the read switch SW ₁ is not selected, it is then determined whether the changeover switch SW ₂ has been operated (step c ₁ ). If the changeover switch SW ₂ has been operated, it is determined whether the display flag F is set, that is, whether the message is being displayed (step c ₂ ). If F is set, the reception date currently displayed is switched to the reception time (or the reception time is switched to the reception date) and displayed, and the upper digit of the message currently displayed is switched to the lower digit. Display (step c ₃ ). In addition,
At this time, switch the reception date and reception time with the switch SW.
_This is performed only while ₂ is being pressed, and switching between the upper digit and lower digit of the message is performed by detecting ON of switch SW ₂ . Then, by setting "0" in the timer register T (step c _4), starts a timer operation for 30 seconds as described above (see step _{a 10, a 11, a 15} , a 16).

On the other hand, if F is not set in step c ₂ above, it means that the normal time is being displayed, so the current time currently displayed is switched to the current date and displayed (step
c ₅ ). This switching is also performed only while the switch SW ₂ is being pressed.

Processing of the above switches SW ₁ and SW ₂ (steps b _{1 to} b ₁₂ and c ₁ to
According to c ₅ ), for example, when the switch SW ₁ is operated in the reception standby state as shown in FIG. 4A, that is, in the normal time display state, FIG.
As shown in (c) and (d), a plurality of messages stored in the memory 8 are displayed in order from the latest message, and the displayed message is the same day (in this case, October 20). If the message was received, the reception time (hour, minute) is displayed with it, while if the message being displayed is something other than the current day's reception, the reception date (month,
Day) is displayed (see Step b ₁ ~b _10). Further, in the display state of the message by the switch SW ₁ of the above, when operating another switch SW _2, if the long text message can not be displayed at one time as shown in FIG. 4 (b), the Upper digit (in this case, "[1] 03-12
3-4 "), the following lower digit (in this case," 567 ") is displayed as shown in FIG. 4 (f), and at the same time, only while the switch SW ₂ is being operated, FIG. 4 (f) is displayed. ),
As shown in (g) and (h), the reception time switches to the reception date (or the reception date to the reception time) (step c ₁
~ C ₃ ). Similarly, if the switch SW ₂ is operated while the current time is being displayed as shown in FIG. 4 (a),
Only during the operation, switches to the current date, as shown in FIG. 4 (e) (see step c _5). Furthermore, if the switch SW ₁ is operated while the last message (reception order is 1) as shown in FIG. 4 (d) is displayed, the normal time as shown in FIG. 4 (a) is displayed. returns to the display (see step b _7, b _12). In Fig. 4 (a), "16:35" indicates that the current time is 16:35, and in Fig. 4 (e), "10-20" indicates that the current date is October 20. It indicates that there is. Further, (b), (c), (d), (f),
In (g) and (h), "10", "9", and "1" indicate the order of message reception, and "A", "B", and "C" indicate call types for identifying the caller. , "12:00", "9:38"
Etc. indicate the reception time, "10-20", "10-19" etc. indicate the reception date, and "[1] 03-123-4567" indicates, for example, "03-1".
"Please call 23-4567", and "[2] 10-20" means, for example, "Please go directly to the site on October 20".
“[3]” indicates a message meaning, for example, “call the company”.

Returning to FIG. 3, when it is determined in step c ₁ that the switch is not the changeover switch SW ₂ , it is then determined whether or not the switch is the reset switch SW ₃ (step d ₁ ). Here, when it is judged that the reset switch SW _3, the alarm flag if G is set, i.e., to determine whether in notification during data reception (see step a ₇₎ (Step d _2), if G is set to stop the notification to reset the G (step d _3). As a result, when new data is received and the notification by the speaker 13 and the LED 15 is started, if this is left as it is, the notification is stopped after 8 seconds have elapsed (steps a ₈ and a _11).
~a reference _14), by operating the reset switch SW ₃ before the elapse 8 seconds, it is possible to stop the broadcast at that time.

On the other hand, if it is not set the alarm flag G in step d _2, followed by the display flag F is set whether it is (see step a ₆ and Step b _4), i.e., the message at the time of data reception time or data read to determine whether being displayed (step d _4).
Here, if F is set, switching from the message display to the normal time display resets the F (step d _5). As a result, when new data is received and a message is displayed, or when a message is read from the memory 8 and displayed by operating the switches SW ₁ and SW ₂ , if this display is left as it is, it takes 30 seconds. Although switched to time display after elapse (step _{a 8, a 15 ~a 17,} b 11
And reference c _4), by operating the reset switch SW ₃ before 30 seconds have elapsed, it is possible to switch the time display from the message display at that time. For example, FIGS. 4 (b) to (d),
In any of the states (f) to (h), the reset switch SW ₃ is used to display the time shown in FIG. 4 (a) (waiting for reception).
You can go back to.

If it is determined in step d ₁ that the reset switch SW ₃ is not the case, the process corresponding to the other key switches is performed (step e ₁ ).

As described above, according to the present embodiment, when a message that has already been stored is displayed, if the message is received on the same day, as shown in FIG. (Hour, minute) is displayed, and if it is other than the same day reception, the reception date (month, day) is displayed together with the message as shown in FIGS. 4 (c) and (d). It is possible to effectively display the date and time of reception together with the message without increasing the size of the display unit 11 or making the displayed characters finer. Moreover, when necessary, by operating the switch SW _2, FIG. 4 (f) ~
Since the reception date and the reception time can be switched and displayed as shown in (h), a more effective display is possible.

[Effect of device]

As described above, according to the present invention, the message received on the same day is displayed together with its reception time, and the message other than the message received on the same day is displayed together with its reception date. The reception date and time can be effectively displayed together with the message. Therefore, there is no need to upsize the display portion or to miniaturize the displayed characters, and accordingly, the problem of complication of the drive circuit is eliminated.
