DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention stores a plurality of fixed messages, and when a received message data includes a code designating the fixed message, restores the corresponding fixed message based on the specified code. Display machine
The present invention relates to an information receiving device having a function .

[0002]

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

Although a mask ROM is usually used as a storage element for storing the plurality of fixed messages, a power-backed-up RAM or EEPROM is used.
In some cases, a rewritable memory such as the one described above allows a user using the message receiver to set an arbitrary fixed message by himself / herself.

A message receiver using a rewritable memory as such a fixed message memory allows a user to store and set an arbitrary message, and that the content once stored can be rewritten later. This is more useful than a fixed fixed message.

[0005]

However, in the above-described message receiver using a rewritable memory as the fixed message memory, the past message stored in the received message storage unit for storing the received message data is stored. When the message is displayed again, the contents of the fixed message memory may be rewritten between the time when the received message is received and the time when the message is redisplayed. There is a possibility that the message content intended by the caller may be different, and the reliability of the message is reduced.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to change the contents of a fixed message memory so as to affect the contents of a stored received message. user of Do changes is to provide an information receiving apparatus capable of preventing to perform unconsciously.

[0008]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the circuit configuration. In the figure, reference numeral 11 denotes an antenna, and a radio wave of a call including a message received by the antenna 11 is transmitted to a radio unit 12. The wireless unit 12 performs intermittent reception by driving the decoder unit 13, amplifies and demodulates a received radio wave, and transmits the radio wave to the decoder unit 13. The decoder unit 13 determines whether or not the called number matches its own identification number. If they match, the identification number of the called unit together with the call detection signal or the calling number is determined. The CPU 14 sends to the CPU 14 call type information indicating what type of call was added to the number and message information received following the call number.

The CPU 14 controls the operation of the other circuits as a whole in accordance with a signal from the decoder 13 and an 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 the processing, an operation register and the like.

The switch input unit 15 has a first switch (“SW1” in the figure) for instructing the switching of the displayed mode.
16), a second switch (shown as "SW2" in the figure) 1 for instructing the display of the next message in the mode, etc.
7. A third switch (shown as "SW3" in the figure) for instructing a switch from the confirmation mode of the fixed message to the registration mode 18, a reset switch (in the figure, "SWR" for instructing the release of the sound or the display of the message) 19) are connected, and a signal corresponding to the operation is transmitted to the CPU.

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 fixed message data registered in advance in page units. While storing 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 A character pattern corresponding to the fixed message information stored in the fixed message memory 21 designated by the number in the received message information is read from a character generator (indicated as "CG" in the figure) 26, and a display unit composed of a liquid crystal display element is read. 27 is displayed as display data.

The display section 27 has a display pattern as shown in FIG. 2, for example. In the figure, the display unit 27 includes a message display unit 27a that displays character information of a received message and a fixed message, a number display unit 27b that displays the arrival order of the received message and the page number of the fixed message, and a display unit that displays the fixed message. A lit fixed mark display 27c is provided.

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

As shown in FIG. 3, the received message memory 20 stores the actually received message information in a flag ("Code F" in the figure) which is set when the message includes a code designating a corrected fixed message. Shown)
The information is stored as a set (hereinafter, referred to as a “page”) for a plurality of pages.

The fixed message memory 21 includes a main memory unit 21a for storing correctable fixed message data as shown in FIG. 4, and a fixed message before correction when a fixed message stored in the main memory unit 21a is corrected. Backup memory section for storing and holding fixed message data
21b.

The main memory unit 21a stores a plurality of pages of fixed message data as a set (page) with a correction flag (indicated as "correction F" in the figure) indicating whether or not there is a correction, and a page number (No.). Things.

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

The backup memory unit 21b stores the uncorrected fixed message data stored in the main memory unit 21a in the order in which the data was written in the backup memory unit 21b and the main memory unit 21a. The page number (shown as "old page number" in the figure) at the time of setting is stored as a set (page) with a designated number.

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

One batch consists of a synchronous codeword followed by eight frames, and one frame consists of two codewords. 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 code word is a code word for a call number (address). The address code word is composed of 19 address bits whose first bit is set to "0", 2 function bits and 11 bit address bits. It is configured with a check bit added. The function bits can be used to distinguish between four types of calls called a multi-address call, and four different sounds and displays can be made for one ID.

On the other hand, the message code word is a code word for message information, and is composed of a 21-bit message bit having a first bit set to "1" and a 1-bit message bit.
It consists of one check bit, and if there is a message, it is transmitted following the address code word. Next, the operation of the above embodiment will be described.

First, the transition state of the operation by operating 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 content of the stored fixed message is checked. The mode cyclically shifts to the "mode", which is not described here, and the "normal mode" is forcibly operated by operating the reset switch 19 from the "standard message confirmation mode" and the "other mode". ".

When the second switch 17 is operated from the "normal mode", the mode shifts to the "received message display mode" for displaying the received message data, and the latest received call stored in the received message memory 20 is received. Display message data. Further, each time the second switch 17 is operated in the “received message display mode”, the received message data stored in the received message memory 20 is displayed in the order of newest incoming call. Then, from the “received message display mode”, the reset switch 19
Is operated, the operation returns to the "normal mode" again.

Further, the above-mentioned "standard message confirmation mode"
In the above, each time the second switch 17 is operated, the fixed messages stored in the main memory section 21a of the fixed message memory 21 are sequentially read and displayed from the first page, and the last fixed message is displayed. When the second switch 17 is operated in the state in which the standard message is not stored, the next page in which the fixed 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 "fixed message confirmation mode", the mode shifts to the "fixed message registration mode" for correcting and registering the fixed message stored in the main memory section 21a of the fixed message memory 21. . In the "regular message registration mode", the digit position for inputting (correcting) is shifted each time the first switch 16 is operated, and the character input each time the second switch 17 is operated is described later. Are sequentially changed and displayed, and an input character is selected. When the third switch 18 is further operated from the "regular message registration mode", the process returns to the "regular message confirmation mode" again.

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

In accordance with the designation of the "fixed message registration mode", the CPU 14 determines whether a fixed message has already been registered in the corresponding page of the main memory 21a (step A3).

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

When there is a corresponding received message, the speaker 23 emits sound, the LED 25 illuminates or blinks, and the number display section 27 of the display section 27.
The user is notified that the contents of the received message will be changed if the fixed message data is directly corrected by means such as displaying the number of received messages corresponding to the search result in step b (step A7).

Thereafter, the operation waits for a switch operation of the first switch 16 to the reset switch 19, and when operated, it is determined which of the first switch 16 to the reset switch 19 is selected (step A8).

When the first switch 16 is operated, the most recent incoming call 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 fixed message part is also restored and displayed on the display unit 27 (step A
9).

Then, the controller waits for the operation of the first switch 16 to the reset switch 19 again, and when operated, determines which of the first switch 16 to the reset switch 19 is operated (step A10).

Here, the first switch 16 is operated again.
Is found, the received message including the designated number for designating the fixed message to be corrected is searched from the received message memory 20 for the newest message after the incoming call (step A12). Is determined (step A13). If there is, the process from step A9 is repeated again to display the corresponding received message.

If it is determined in step A10 that the second switch 17 has been operated, the received message currently displayed on the display unit 27 at that time is deleted from the received message memory 20 (step A10). Step A11) Then, 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 correction of the fixed message is stopped, and the code flag of the corresponding received message in the received message memory 20 set in step A5 is determined. Reset (step A22), and then reset control flags such as a registration mode flag and a correction mode flag (step A20). Then, the process is completed, and the process returns to the "fixed message confirmation mode". The corresponding page of the main memory section 21a displayed in step A1 is displayed.

In step A3, the main memory section
If it is determined that no fixed message has already been registered in the corresponding page of 21a, and if it is determined in step A6 that there is no received message including the designated number of the fixed message to be corrected, the process proceeds to step A8 or A10. If it is determined that the reset switch 19 has been operated in step S13, and if it is determined in step A13 that there is no more received message data in the received message memory 20, the display unit 27 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 end the registration and return to the "standard message confirmation mode" (step A16). Thereafter, it is determined whether or not the correction mode flag in the CPU 14 is set when the third switch 18 is operated (step A17).

If it is set, the fixed message data and its page number stored in the main memory unit 21a which have not been corrected at this time are transferred to the backup memory unit 21b and stored and held as a backup ( Step A18). At this time, if the backup memory unit 21b is in the full storage state, the oldest one in the write order is deleted and stored at that position.

Thereafter, the fixed message data newly set by the data input is stored in the fixed message memory 21.
In addition to the correction registration in the main memory unit 21a, the code flag is set (step A19), and the control flags such as the registration mode flag and the correction flag are reset (step A20). The process returns to the “fixed message confirmation mode”, and the registered fixed message is displayed in a meaning of confirmation.

If it is determined in step A17 that the correction mode flag has not been set, the fixed message data is not corrected but new fixed message data.
The page designated and selected in the main memory unit 21a is registered as it is (step A21), and thereafter, control flags such as a registration mode flag and a correction mode flag are reset (step A20). Ends,
Returning to the "fixed message confirmation mode", the registered new fixed message is displayed for confirmation. Next, the contents of processing in the "received 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, received message data to be displayed is selected from those stored in the received message memory 20 and displayed (step B1). As the selection processing at this time, when the mode is simply shifted from the "normal mode" to the "received message display mode" by operating the second switch 17, the latest received message data of the incoming call is selected, and there is an incoming call. At that time, after performing notification of reception by the speaker 23 and the LED 25 and storage of the received message data in the received message memory 20, the received message data stored is selected,
When the second switch 17 is operated continuously, the received message data in the received message memory 20 is updated and selected in the order of the incoming call according to the number of times of operation.

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

If the flag has been set, it means that the flag has been set by the processing of step A5 in FIG.
Since the fixed message specified in the received message has been corrected, the received message memory 20
Is displayed as it is, and the process ends (step B7). FIG. 8A exemplifies the display state, in which “0” of the number display section 27b is displayed.
"9" indicates the reception order, "[[" in the message display 27a indicates a code indicating that the two-digit number following this is the designated number of the fixed message, "01" indicates the designated number,
"03-1234-5678" indicates the telephone number, and the fixed message is not restored and displayed, so that the message is not erroneously recognized by correcting the fixed 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 section 21b of the fixed message 21, and the corresponding fixed message is searched. If there is no such message, a message to that effect is displayed. If there is such a message, it corresponds to the designated number before correction stored in the backup memory unit 21b of the fixed message memory 21 as shown in FIG. To 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" in the message display section 27a indicates the contents of the fixed message data, and the fixed mark display 27c.
Is also displayed.

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

If it is determined in step B2 that the code flag is not set in the corresponding page in the received message memory 20 storing the received message selected, the next step is to determine the fixed message in the received message. Is determined based on the presence or absence of the designation code "[[" (step B3).

If no fixed message is specified, the received message itself stored in the received message memory 20 is displayed as it is (step B7).
Is specified, it is determined whether a correction flag corresponding to the fixed message data is set in the specified page in the fixed message memory 21 (step B4).

If set, the received message displayed and selected in step B1 is received after correcting the fixed message specified in the message data, but the contents of the fixed message are sent to the caller. May have forgotten to notify that the change has been made, or may have forgotten that the caller has been changed, so the main memory unit 21a of the fixed message memory 21 is used as the designated fixed message.
Is restored and displayed, and the restoration display section of the fixed message is blinked in order to clearly indicate that the fixed message has been corrected, and this processing is terminated (step B5). FIG. 9A exemplifies the display state, in which the reception order "09" is displayed on the number display section 27b, and the fixed message data "call the next time" is blinking displayed on the upper part of the message display section 27a. And the telephone number “03-1234-56”
78 ”is displayed.

When the first switch 16 is operated in this display state, the same search and display processing as described with reference to FIG. 8 is performed. That is, when a fixed message corresponding to the fixed message designation number "01" is found in the backup memory unit 21b of the message memory 21, the backup memory unit 21b of the fixed message memory 21 as shown in FIG. The fixed-form message data before correction stored in and stored in is read out and displayed on the display unit 27. As in the case of FIG. 8B, "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 contents of the fixed message data. The mark display 27c is also displayed. Thereby, the contents of the fixed message before correction can be confirmed. Also in this case, instead of this display method,
The fixed 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.

If 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 fixed message portion stored in the main memory 21a of the fixed message memory 21 is restored and displayed as it is, and the process is terminated (step B6). In the display state, the blinking display portion in FIG. 9A is a stationary lighting display.

In the above-described received message display processing, if it is determined in step B2 of the flowchart shown in FIG. 7 that the code flag is set,
In other words, if the fixed message specified in the received message selected to be displayed has been corrected after receiving the received message, the received message data itself is deleted, as in the case of displaying the received message without specifying the fixed message. Although the display is configured to be displayed, the receiver according to the present embodiment includes the backup memory unit 21b for storing the fixed message before correction and its designated number (old page number) in the fixed message memory 21. If it is determined in B2 that the code flag has been set, the received message data itself is not immediately displayed, but the backup memory unit 21b is searched for a specified number that matches the specified number in the received message, and matches. If there is a designated number, the value before correction stored in the backup memory unit 21b is used. Restore and display the type message,
The received message data itself may be displayed only when there is no matching designated number.

In the above embodiment, the "regular message registration mode" is one of the main modes selected by operating the first switch 16, and the "regular message confirmation mode" is selected.
Has been described as a subordinate mode.
It can also be one.

In this case, one control switch is added to make a total of five switches. The transition state of the operation by operating each switch is as shown in FIG. That is, each time the first switch 16 is operated from the “normal mode” in which the message is received and the switch input is waited, the “standard message confirmation mode” in which the content of the stored standard message is checked, Main memory section 21
The mode is cyclically shifted to a “standard message registration mode” for correcting and registering the standard message stored in the “a”, and “other modes” not described here. Reset switch 19 from “registration mode” and “other mode”
By operation of, the mode is forcibly returned to the “normal mode”.

The operation is switched from the "normal mode" to the "received message display mode" by operating the second switch 17, and the newest received message data of the incoming call is displayed. further,
Each time the second switch 17 is operated in the "received message display mode", the received message received message data is displayed in the order of newest incoming call. Then, the operation returns to the “normal mode” from the “received message display mode” by operating the reset switch 19 again.

Further, the above-mentioned "regular message confirmation mode"
Each time the second switch 17 is operated, a fixed message memory
The standard messages stored in the main memory unit 21a of the main unit 21 are sequentially read out from the first page and displayed. When the second switch 17 is operated while the last standard message is displayed, the standard message on the first page is again displayed. Is displayed.

In the "regular message registration mode", page switching is selected each time the second switch 17 is operated, and the digit position for inputting (correcting) 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.

When the "regular message registration mode" is one of the main modes selected by operating the first switch 16 as described above, the fixed message registration process will be described with reference to the flowchart shown in FIG. become that way.

First, the processing order of steps A1 and A2 is reversed, and when one of the fourth switch and the fifth switch is operated, the processing of step A3, that is, the corresponding page of the main memory unit 21a is already written. The process of determining whether a fixed message has been registered is started.
Other processes are almost the same, and only steps A8, A10 and A
The switches determined in the process of step 16, ie, the first switch 16, the second switch 17, and the third switch 18 need only be replaced with, for example, the fourth switch, the fifth switch, and the second switch 17, respectively.
