Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention stores a plurality of standard messages and, when the received message data includes a code for designating the standard message, restores and displays the corresponding standard message based on the specified code. About message receiver to do.

[0002]

2. Description of the Related Art Conventionally, a display function for storing a plurality of standard messages and restoring and displaying a corresponding standard message based on the specified code when the received message data includes a code for designating the standard message. Message receivers with are widely used.

Although a mask ROM is normally used as a storage element for storing the above-mentioned plural fixed messages, a RAM or an EEPROM backed up by a power source is used.
There is also a rewritable memory such as that which enables the user himself / herself who uses the message receiver to set an arbitrary fixed message.

In the message receiver using a rewritable memory as such a fixed message memory, the user can store and set an arbitrary message, and the contents once stored can be rewritten later. Therefore, it is more useful than one that stores a fixed fixed message.

[0005]

However, in the message receiver using the rewritable memory as the above-mentioned fixed message memory, the past reception stored in the reception message storage unit for storing the received message data. When the message is displayed again, the contents of the standard message memory may have been rewritten between the time when the received message was received and the time when the message was redisplayed. Therefore, the message data output by the redisplay and this message There is a possibility that the message content intended by the caller may be different, and there is a risk that the user may misidentify the message.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a message receiver in which there is no possibility of misrecognizing the content of a received message even when the content of the standard message memory is changed. To provide.

[0007]

That is, the present invention is provided with a received message memory for storing received message data and a fixed message memory for storing a plurality of fixed messages in advance. When the specified fixed message is rewritten and changed, the identification information indicating that the fixed message is changed corresponding to the stored received message is stored, and the received message is displayed when the stored received message is displayed. If the identification information corresponding to is stored, the designated message is restored and displayed as if the designated message is not rewritten, and if the identification information is stored, the designated message is rewritten. Messages that include a specified code that specifies a boilerplate message as being Is displayed as it is.By distinguishing the display form of the received message including the designated code of the fixed message depending on whether the contents of the fixed message memory are changed, the contents of the received message can be mistakenly recognized. It can be surely prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the circuit configuration. In the figure, 11 is an antenna, and the radio wave of the call including the message received by the antenna 11 is sent to the radio unit 12. The wireless unit 12 performs intermittent reception by driving the decoder unit 13, amplifies and demodulates a received radio wave, and sends it to the decoder unit 13. The decoder unit 13 determines whether or not the called number matches its own identification number, and if they match, which identification number of its own the called number was with the call detection signal, or It sends to the CPU 14 call type information indicating what kind of call was added to the number and message information received subsequently to the call number.

The CPU 14 controls the operation of the entire other circuit according to the signal from the decoder unit 13 and the input signal from the switch input unit 15, and registers a ROM storing various control programs, a timer, and a fixed message. It is composed of various control flags such as a registration mode flag and a correction mode flag used in processing, an arithmetic register and the like.

The switch input section 15 has a first switch ("SW1" in the figure) for instructing switching of the displayed mode.
16), the second switch (indicated as "SW2" in the figure) for instructing the display of the next message in the mode 1
7. The third switch (shown as "SW3" in the figure) for instructing switching from the confirmation mode of the standard message to the registration mode, and the reset switch (indicated as "SWR" in the figure for releasing sound or in the middle of message display) (Shown) 19 and the like are connected, and a signal according to the operation is sent to the CPU 14.

The CPU 14 is connected to a received message memory 20 for storing a plurality of received message data and a fixed message memory 21 for storing pre-registered fixed message data in page units, and receives received message information and the like. While being stored in the memory 20, a sound emission signal is sent to the speaker 23 via the amplifier 22 and a lighting signal is sent to the LED 25 via the amplifier 24 to notify that there is a call, and the received message information or The character pattern corresponding to the fixed message information stored in the fixed message memory 21 numbered in the received message information is read from the character generator (indicated as "CG" in the figure) 26, and the display unit composed of the liquid crystal display element is read. Display on 27 as display data.

The display unit 27 has a display pattern as shown in FIG. 2, for example. In the figure, on the display unit 27, a message display unit 27a for displaying character information of a received message or a fixed message, a number display unit 27b for displaying the order of arrival of the received message and the page number of the fixed message, and a fixed message are displayed. A standard mark display 27c that lights up is provided.

The message display section 27a is composed of a dot matrix and can display 12 characters × 2 lines. Further, the number display portion 27b is constituted by a day-shaped segment display and can display a two-digit number.

As shown in FIG. 3, the reception message memory 20 sets a flag ("code F" in the figure) which is set when actually received message information has a code designating a corrected fixed message in the message. Indicates)
A plurality of pages are stored in combination with information (hereinafter referred to as “page”).

The fixed message memory 21 has a main memory portion 21a for storing correctable fixed message data as shown in FIG. 4, and a fixed message before correction when the fixed message stored in the main memory portion 21a is corrected. Backup memory unit that stores and retains standard message data
21b and.

The main memory unit 21a stores the fixed message data as a set (page) with a correction flag (indicated as "correction F" in the figure) indicating the presence or absence of correction and a page number (No.). It is a thing.

The fixed messages stored in the main memory portion 21a are all designated by page numbers, and the designated number for designating fixed messages and the page number are the same.

The backup memory unit 21b stores the standard message data before correction stored in the main memory unit 21a in the order in which the data was written in the backup memory unit 21b and in the main memory unit 21a. A plurality of pages are stored as a set (page) with a specified page number (indicated as "old page number" in the figure) at that time.

Here, the signal is received by the antenna 11, and the radio unit 12
The configuration of the selective call signal demodulated in 1. will be described.
For example, the selective call signal of the POCSAG system, which has become an international standard, is composed of a header part for synchronizing bits, which is a preamble, and a data part, which is one or more N consecutive batches.

[0021] One batch includes a sync code word followed by eight frames, and one frame includes two code words. There are two types of codewords, an address (ID-number) codeword and a message codeword, both of which are composed of 32 bits.

The address codeword is a codeword for a calling number (address), which is an address bit consisting of 19 bits in which the first bit is set to "0", and a function bit of 2 bits and an 11 bit. It is configured with a check bit added. The function bits can distinguish four types called multi-address calls, and four different sounds and displays can be made for one ID.

On the other hand, the message codeword is a codeword for message information, and a message bit consisting of 21 bits in which the first bit is set to "1" and 1
It consists of one check bit, and if there is a message, it is transmitted following the address codeword. Next, the operation of the above embodiment will be described.

First, the transition state of the operation by the operation of the first switch 16, the second switch 17, the third switch 18 and the reset switch 19 connected to the switch input section 15 will be described with reference to FIG.

As shown in the figure, every time the first switch 16 is operated from the "normal mode" in which a message is received and a switch input is waited, the contents of the stored standard message are confirmed. The mode is cyclically changed to “mode”, “other mode” not described here, and the “normal mode” is forcibly operated by operating the reset switch 19 from these “standard message confirmation mode” and “other mode”. It returns and shifts to.

When the second switch 17 is operated from the "normal mode", the "reception message display mode" for displaying the received message data is entered, and the latest reception of the incoming call stored in the received message memory 20 is received. Display message data. Further, every time the second switch 17 is operated in this "reception message display mode", the reception message data stored in the reception message memory 20 is displayed in the new order of arrival. Then, from this "received message display mode", reset switch 19
When is operated, the mode is returned to the “normal mode” again.

In addition, the above "standard message confirmation mode"
In FIG. 3, the fixed message stored in the main memory portion 21a of the fixed message memory 21 is read and displayed sequentially from the first page every time the second switch 17 is operated, and the last fixed message is displayed. When the second switch 17 is operated in the closed state, the next page in which the standard message is not stored is displayed.
When the switch 17 is operated, the standard message on the first page is displayed again.

When the third switch 18 is operated from the "standard message confirmation mode", the mode is shifted to the "standard message registration mode" for correcting and registering the standard message stored in the main memory portion 21a of the standard message memory 21. .. In the "standard message registration mode", the digit position for inputting (correcting) is shifted each time the first switch 16 is operated, and the character to be input each time the second switch 17 is operated, as will be described later in detail. Are sequentially changed and displayed, and the input character is selected. When the third switch 18 is further operated from the "standard message registration mode", the mode is returned to the "standard message confirmation mode" again.

The contents of the registration process of the fixed message will be described with reference to FIG. When newly registering or correcting a fixed message, first in the "fixed message confirmation mode", the page of the main memory portion 21a of the fixed message memory 21 is selected by operating the second switch 17 (step A1). As a result, the selected standard message and its page number are displayed in the main memory section 21.
It is read from a and displayed on the message display section 27a and the number display section 27b of the display section 27. As described above, with the arbitrary page selected, the "fixed message registration mode" is designated by operating the third switch 18 as shown in FIG. 5 (step A2).

With the designation of the "standard message registration mode", the CPU 14 determines whether or not a standard message has already been registered in the corresponding page of the main memory portion 21a (step A3).

If it is determined that the standard message has already been registered, the standard message is corrected, so the CPU 14 indicating that the standard message registration process this time corresponds to the standard message correction process.
The correction mode flag is set (step A4).
Then, the code for designating the fixed message to be corrected, that is, the received message including the designated number of the fixed message is searched in the received message memory 20, and if there is, the code of the page in which the received message is stored. The flag is set (step A5). After that, as a result of the search, it is determined whether or not there is a received message including the designated number of the fixed message to be corrected (step A6).

When there is a corresponding received message, the speaker 23 emits a sound, the LED 25 lights or blinks, and the number display section 27 of the display section 27 is displayed.
It is informed that if the standard message data is corrected as it is by a means such as displaying the number of received messages corresponding to the search result in b, the contents of the received message will be changed (step A7).

Thereafter, the operation of the first switch 16 to the reset switch 19 is awaited, and when operated, it is determined whether the switch is the first switch 16 to the reset switch 19 (step A8).

When the operated switch is the first switch 16, the latest received message among the received messages including the designated number for designating the fixed message to be corrected is read from the received message memory 20. , The standard message section is also restored and displayed on the display section 27 (step A
9).

Then, the operation of the first switch 16 to the reset switch 19 is awaited again, and when operated, it is determined whether the switch is the first switch 16 to the reset switch 19 (step A10).

The one operated here is the first switch 16 again.
If it is, the received message memory 20 is searched for a newest incoming message next to the incoming message including the designated number designating the fixed message to be corrected (step A12), and the corresponding received message data is received. It is judged whether or not there is still any (step A13). If there is, the process from step A9 is repeated again and the corresponding received message is displayed.

When it is determined that the second switch 17 is operated in step A10, the received message displayed on the display unit 27 at that time is erased from the received message memory 20 ( Step A11) and thereafter, the process from step A12 is repeated to search for the next corresponding received data.

If it is determined in step A8 or A10 that the third switch 18 has been operated, the code flag of the corresponding received message in the received message memory 20 set in step A5 is set to stop the correction of this fixed message. After resetting (step A22), the control flags such as the registration mode flag and the correction mode flag are reset (step A20), and the process is completed. The corresponding page of the main memory portion 21a displayed in step A1 is displayed.

In step A3, the main memory section is
If it is determined that the standard message is not already registered in the corresponding page of 21a, or if there is no received message including the designated number of the standard message to be corrected in step A6, step A8 or A10 is performed. When it is determined that the reset switch 19 has been operated in step S13 and when it is determined that there is no corresponding received message data in the received message memory 20 in step A13, the display unit 27 then displays the registration mode. After (step A14), input processing of data to be registered is performed by operating the first switch 16 and the second switch 17 (step A15). The data input process is continued until the third switch 18 is operated to complete the registration and return to the "standard message confirmation mode" (step A16). After that, when the third switch 18 is operated, it is determined whether or not the correction mode flag in the CPU 14 is set (step A17).

If it is set, the standard message data which is stored in the main memory portion 21a and has not been corrected at the present time and its page number are transferred to the backup memory portion 21b to be stored and retained for backup. Step A18). At this time, if the backup memory unit 21b is in the full storage state, the oldest write order is erased and stored at that position.

After that, the standard message data newly set by the above data input is transferred to the standard message memory 21.
In addition to correcting and registering it in the main memory unit 21a, the code flag is set (step A19), and then the control flags such as the registration mode flag and the correction flag are reset (step A20). When finished, it returns to the “standard message confirmation mode” and displays the registered standard message for confirmation.

If it is determined in step A17 that the correction mode flag is not set, the standard message data is not corrected but new standard message data, and therefore the standard message memory 21.
The selected and designated page of the main memory section 21a is registered as it is (step A21), and then control flags such as a registration mode flag and a correction mode flag are reset (step A20). Exit
Return to the "standard message confirmation mode" to display the registered new standard message for confirmation. Next, the contents of processing in the "reception message display mode" performed by operating the second switch 17 from the "normal mode" will be described with reference to FIG.

In the "received message display mode", first, the received message data to be displayed is selected from the ones stored in the received message memory 20 and displayed (step B1). As the selection process at this time, when the "normal mode" is simply switched to the "received message display mode" by operating the second switch 17, the latest received message data of the incoming call is selected and the incoming call is received. In that case, after the reception notification by the speaker 23 and the LED 25 and the storage of the reception message data in the reception message memory 20 are performed, the reception message data stored is selected,
When the second switch 17 is continuously operated, the received message data in the received message memory 20 is updated and selected in the newest incoming order in accordance with the number of operations.

Thereafter, it is judged whether or not the code flag is set in the corresponding page in the received message memory 20 storing the selected received message (step B2).

If it is set, it means that the flag has been set by the processing of step A5 in FIG.
Since the standard message specified in the received message has been corrected, the received message memory 20
The received message itself stored in is displayed as it is, and this process ends (step B7). FIG. 8A shows an example of the display state.
“9” indicates the order of reception, “[[” in the message display section 27a indicates a code indicating that the subsequent two-digit numerical value is the designated number of the fixed message, and subsequent “01” indicates the designated number.
Since "03-1234-5678" indicates a telephone number, respectively, and since the standard message is not restored and displayed, the message is not erroneously recognized due to the correction of the standard message.

When the first switch 16 is operated in this display state, the fixed message corresponding to the fixed message designation number "01" is searched in the backup memory portion 21b of the fixed message 21, and the corresponding fixed message is searched. If there is not, it is displayed, but if there is, it corresponds to the designated number before correction stored and retained in the backup memory unit 21b of the standard message memory 21 as shown in FIG. 8B. Read the fixed message data,
It is displayed on the display unit 27. Here, "01" in the number display section 27b
Is the old page number corresponding to the fixed message designation number,
“Call the next number” on the message display 27a indicates the content of the standard message data, and the standard mark display 27c
Is also displayed.

With this display, the exact content of the received message can be confirmed. When confirming the content of the received message, instead of this display method, the fixed number message before correction is interrupted in the designated number part and restored and displayed as in the case of the display of the normal received message including the fixed message designation number. You can also

If it is determined that the code flag is not set in the corresponding page in the received message memory 20 storing the received message selected in step B2, the standard message in the received message is next. Is designated by the presence or absence of the designated code "[[" (step B3).

When the fixed message is not designated, the received message itself stored in the received message memory 20 is displayed as it is (step B7).
However, if it is specified, it is then determined whether or not the correction flag corresponding to the fixed message data is set in the corresponding page in the specified fixed message memory 21 (step B4).

If set, the received message displayed and selected in step B1 has been received after correcting the fixed message specified in the message data, but the contents of the fixed message to the calling party are May be forgotten to notify that the caller has changed, or because the caller may have forgotten that the caller has been changed, the main memory section 21a of the standard message memory 21 is designated as the standard message.
The standard message stored in is restored and displayed. In order to clearly show that the standard message has been corrected, the standard message restoration display section is displayed in a blinking manner and this process is terminated (step B5). FIG. 9 (a) shows an example of the display state. The reception order "09" is displayed on the number display section 27b, and the standard message data "Call me at the next time" is displayed in blinking on the upper part of the message display section 27a. At the same time, the telephone number "03-1234-567"
8 ”is displayed.

When the first switch 16 is operated in this display state, the same search and display processing as that described with reference to FIG. 8 is performed. That is, when there is a fixed message corresponding to the fixed message designation number “01” in the backup memory unit 21b of the message memory 21, as shown in FIG. 9B, the backup memory unit 21b of the fixed message memory 21 is shown. The standard message data before correction stored and stored in is read out and displayed on the display unit 27. As in the case of FIG. 8B, here, "01" in the number display section 27b indicates the old page number, and "Call the next number" in the message display section 27a indicates the content of the standard message data. The mark display 27c is also displayed. As a result, the contents of the standard message before correction can be confirmed. Also in this case, instead of this display method,
The standard message before correction may be restored and displayed as a part of the received message, that is, in the display mode shown in FIG. 9B.

When it is determined in step B4 that the correction flag corresponding to the fixed message data is not set in the corresponding page in the specified fixed message memory 21, the specified fixed message is corrected. Therefore, the standard message part stored in the main memory portion 21a of the standard message memory 21 is restored and displayed as it is, and this process is terminated (step B6). The display state is such that the blinking display portion of FIG. 9A is a stationary lighting display.

In the above embodiment, the "fixed message registration mode" is one of the main modes selected by the operation of the first switch 16 and is the "fixed message confirmation mode".
It was explained as a mode subordinate to
You can also choose.

In this case, one control switch is added to make a total of five, and the transition state of the operation due to the operation of each switch is as shown in FIG. That is, every time the first switch 16 is operated from the "normal mode" for receiving a message and waiting for a switch input, the "standard message confirmation mode" for confirming the content of the stored standard message in the standard message memory 21. Main memory section 21
The "regular message registration mode" for correcting and registering the regular message stored in a and the modes other than "other modes" not described here are cyclically changed, and these "regular message confirmation mode" and "standard message" Reset switch 19 from "Registration mode" and "Other modes"
Operate to forcibly return to "normal mode".

The "normal mode" is changed to the "reception message display mode" by operating the second switch 17, and the latest reception message data of the incoming call is displayed. further,
Every time the second switch 17 is operated in the "received message display mode", the received message received message data are displayed in the newest incoming order. Then, the "reception message display mode" is returned to the "normal mode" by operating the reset switch 19.

In addition, the above "standard message confirmation mode"
Every time the second switch 17 is operated with
The standard messages stored in the main memory unit 21a of 21 are sequentially read and displayed from the first page, and when the second switch 17 is operated with the last standard message displayed, the standard message of the first page is displayed again. Is displayed.

In the "standard message registration mode", page switching selection is performed each time the second switch 17 is operated, and the digit position for input (correction) is shifted each time the fourth switch is operated. On the other hand, every time the fifth switch is operated, the characters to be input are sequentially changed and displayed, and the input characters are selected.

Thus, referring to the flowchart shown in FIG. 6, the routine message registration processing in the case where the "routine message registration mode" is one of the main modes selected by the operation of the first switch 16 is as follows. become that way.

First, the processing order of steps A1 and A2 is reversed, and when either the fourth switch or the fifth switch is operated, the processing of step A3, that is, the corresponding page of the main memory section 21a has already been written. A process for determining whether or not a standard message is registered is started.
The other processes are almost the same, with only steps A8, A10 and A
It is only necessary to replace the switches determined in the processing of 16, that is, the first switch 16, the second switch 17, and the third switch 18 with, for example, the fourth switch, the fifth switch, and the second switch 17, respectively.
