Abstract

PURPOSE:To miniaturize the title receiver by writing an identification code to the selective call receiver or transferring the code for rewrite in a radio wave or through a physical line to eliminate the need for mount/dismount of an identification code storage memory, thereby miniaturizing the memory itself and eliminating the need for the accommodation space a socket or the like. CONSTITUTION:By receiving an ID code from an individual number writer 60 to the selective call receiver 70, the ID code in a storage area 50 of the selective call receiver 70 can be written while mounting the storage area 50 for the ID code in the receiver, as it is. Thus, the labor and the time required for the write are reduced remarkably, thereby improving the job efficiency.

Description

[Detailed Description of the Invention] [Purpose of the Invention (Field of Industrial Application) This invention relates to the field of a radio selective calling system in which a selective calling signal is sent from a base station to a plurality of selective calling receivers over a radio channel. , and particularly relates to a selective calling system that effectively stores and transmits identification number (ID) codes of selective receivers.

(Prior Art) Conventionally, a selective calling method has been used as one of mobile communication methods. In this type of system, a call request for an arbitrary selective call receiver is sent from a landline telephone line to a base station via, for example, a selective call switch. When the base station receives a call request, the base station transmits the individual number code (
ID code) is inserted into a selective call signal. This selective call signal is sent to a predetermined part of the call word at a timing assigned to the group to which the selective call receiver belongs.
The code is inserted and sent. This allows a desired selective call receiver to be selectively called.

FIG. 11 shows an example of a schematic configuration of a conventional selective call receiver used in this type of system. This selective call receiver receives a selective call signal sent from a base station (not shown) via an antenna 1 in a radio circuit 2, demodulates it in a demodulation circuit 3 including an error correction section, and introduces the signal into a code matching circuit 4. There is. This code matching circuit 4 is capable of rewriting the individual number, that is, the identification (ID) code inserted in the selective call signal, and has a code that is pre-stored in a storage unit (ID memory) 5 consisting of a one-drive only memory (ROM). Check with the machine number code. Further, the code matching circuit 4 is configured to supply a ringing signal to the drive circuit 6 to generate a ringing sound from the speaker 7 when both codes match, thereby notifying the owner that a call has occurred. There is.

In addition, in the case of a selective calling receiver with a display function as shown in Fig. 12, when a call to the own machine is detected by matching the individual number code, the call is notified by a ringing sound as described above. At the same time, the code matching/message processing circuit 4' receives and decodes the message code sent from the base station together with the individual number code, and displays the message code on a display, such as a liquid crystal display.

Therefore, if the selective call receiver of FIG. 11 is used,
The subscriber can clearly know that a call has been made to him/her by the ringing sound from the speaker 7.

In addition, in the case of the display function shown in FIG. 12, by visually confirming the message displayed on the display in addition to the above-mentioned sound, it is possible to know, for example, the telephone number of the contact and the name of the caller.

By the way, as mentioned above, each of these selective call receivers has a unique identification code, but this identification code needs to be written first, and is also unique to the owner. It may be necessary to make changes later due to changes. Therefore, in the conventional selective call receiver, for example, the ID memory 5 storing the identification code is inserted into the socket 8.
It has a structure that allows it to be attached to and detached from the receiver.

If it becomes necessary to write an identification code or change it later, especially in the latter case, the ID memory 5 should be replaced with another ID memory in which a new identification code has been written, or the ID memory 5 should be replaced with another ID memory with a new identification code written therein. This is handled by removing the ROM from the socket 8, writing or rewriting the identification code using an external ROM writer 9, and then reinstalling the ROM. Therefore, writing or changing the identification code of such a selective call receiver appears to be relatively easy.

(Problem to be solved by the invention) However, in reality, there are many problems as follows.

First, in such a conventional receiver, in order to write or rewrite the identification code, the storage section (ID memory) 5 for storing the identification code must be configured to be detachable from the receiver as described above. It depends. That is, it is necessary to provide the receiver with the socket 8 as described above, and to use a DIP type package in which the ID memory 5 can also be attached and detached. This has been a major obstacle in efforts to make receivers more compact and reduce the number of parts. That is, such conventional selective call receivers have to use a relatively large ROM as the ID memory 5 because it is necessary to attach and detach the ID memory 5 in order to write and rewrite the identification (ID) code. Moreover, there is socket 8 inside the receiver.
It is also necessary to secure accommodation space for , t; If. Therefore, there was a problem in that the configuration of the receiver became large.

In addition, each time you write or rewrite an identification code, you must remove the lid of the receiver case (not shown) and attach/detach the storage unit, so it is necessary to write the identification code for one receiver. It took a lot of effort and time to rewrite and rewrite the data, resulting in low work efficiency.

The present invention has been made in view of the above points, and one object thereof is to provide a selective calling system having an effective identification code transfer function.

Another object of the present invention is to make it unnecessary to attach and detach the memory for storing the identification code, thereby downsizing the memory itself, eliminating the need for accommodation space such as a socket, and making the receiver more compact. The object of the present invention is to provide a selective call receiver that can easily perform the following operations.

Another object of the present invention is to make it possible to write an identification code without removing the storage unit for storing the identification code from the receiver, thereby increasing the efficiency of writing the identification code and reducing the size of the receiver. An object of the present invention is to provide a method for writing an identification code of a selective call receiver.

Still another object of the present invention is to provide a selective call receiver which is capable of reducing the size of the battery and improving battery retention, and which also allows for easy transfer and storage of identification codes.

[Structure of the Invention (Means for Solving the Problem) According to one aspect of the present invention, a selective call receiver includes a specific code for transmitting a selective call signal or identification code transmitted on at least one wireless channel. The selective calling signal or specific code is detected at the same time as the selective calling signal is received.

In addition, in response to the detection of the specific code, this selective call receiver stores an identification code received in association with the specific code in the memory of the receiver, and an identification code that is the same as the identification code stored in the receiver. The user is notified in response to the detection of a calling signal including the code.

According to another aspect of the invention, a selective call receiver includes a receiving circuit, a microprocessor, and an indicator. The receiving circuit receives signals transmitted on one or more wireless channels. The microprocessor has a memory area incorporated therein for detecting a specific code from the received signal, and in response to the detection of the specific code, receiving information associated with the specific code in the memory area. The identification code will be memorized.

The microprocessor further detects an identification code in the received signal that is the same as the stored identification code and controls the indicator to provide instructions to a user in response to detection of the identification code. .

According to another aspect of the invention, a selective call receiver is provided with a connection terminal that is connectable to an external writing device. When the connection terminal is connected to the external storage device, the identification code generated by the external writing device is transmitted, and in response to activation of a switch provided on the selective call receiver side, the identification code is transmitted to the receiver. is memorized.

Further, according to another aspect of the invention, at least one indication is provided to the user upon completion of storing the identification code.

(Operation) The selective call receiver is equipped with a control device that controls its operation in an integrated manner, and the control device may have a built-in memory area for holding the identification code of the receiver. This built-in memory area or a separate ID memory device
Several forms can be taken to preserve the D number. It is mainly divided into two types: one is that when a specific code is transmitted from a specific transmitting device or base station via a wireless line, the selective call receiver detects it and continues to send it; . The ID code is written in the memory area of the control device or a separate ID memory device. On the other hand, the selective call receiver is provided with a connection terminal for writing an ID number, and when a writing device is physically connected to this terminal, the ID number is stored in the memory area of the control device or in a separate ID memory.・Written to the device. Furthermore, when these writings are completed, the user is notified.

(Embodiment) FIG. 1 shows a schematic configuration of a selective call receiver 70 and an individual number writing device 60 in a first embodiment of the present invention. In this figure, the same parts as those in the above-mentioned figure S11 are given the same reference numerals and detailed explanations will be omitted.

First, the individual number writing device 60 includes a code generator 10 and a code transmitter 11 having a transmitting antenna 12.

Among these, the code generator 11 is composed of, for example, a ROM writer, and outputs a specific number code (hereinafter referred to as a specific code) indicating that it is in the writing mode of an individual number code (hereinafter referred to as an identification or ID code) and a new identification code. . Further, the code transmitter 11 transmits the specific code and identification code in the same format as a normal selective call signal transmitted from the base station.

Here, as shown in FIGS. 3A and 3B, a normal selective paging signal consists of time-dividing one frame for each zone into a plurality of groups (for example, n groups), and further dividing these groups into a preamble word and a plurality of paging signals. The call word is time-divided into words (for example, m words), and the individual number code of the selective call receiver is inserted into each of these call words, and then sent from the base station.

Note that these call words are, for example, the so-called BC, which has i bits of information bits and bits of check bits added.
Consists of H code. In this embodiment, the code transmitter 1
1 inserts the specific code output from the code generator 10 into any call word of the selective call signal shown in FIG. 3B, and inserts the new ID code into the next call word following this call word. and transmit from the transmitting antenna 12.

The selective call receiver 70 includes an antenna 1 that receives radio signals, a radio circuit 2 that extracts and receives radio signals of a predetermined frequency, a demodulation circuit 3 that synchronizes the received signals, and an integrated operation of the selective call receiver 70. a control circuit 40 that controls the speaker 7, a speaker 7 that produces a sound such as a ringing tone, a drive circuit 6 that drives the speaker 7 so that the speaker 7 produces a sound under the control of the control circuit 40, and a control circuit. a display 80 for displaying received messages, guidance messages, etc. under the control of 40;
The main component is a mode setting switch 90 for setting the ID code writing mode.

The control circuit 40 is an EEPROM (Electrically Erasable Programmable Read Only Memory) 401, R
It consists of a microprocessor with a built-in OM (Read Only Memory) 402, and its EEPI? 0M401
A memory area 42 in which a specific code for instructing writing of an ID code for verification is stored and a memory area 50 in which the ID code is stored are set in the ROM 40.
2 stores a program to be executed by the logic unit 41. Further, the control circuit 40 includes a logic unit 41, and the logic unit 41 first stores in the memory area 50 the ID code inserted into the selective call signal received and demodulated by the radio circuit 2 and the demodulation circuit 3. It is compared with the ID code of the own machine, and if the two codes match, a ring tone is generated from the speaker 7 via the drive circuit 6, and if a message is received, the display 80 is driven to display the message. Make it visible. Further, if the above codes do not match and the ID code writing mode is set by the mode setting switch 90, the above ID code is compared with a specific code stored in the memory area 42, and both codes are checked. If they match, the logic unit 41 writes into the memory area 50 the new ID code inserted into the call word received following the selective call signal in which the specific code was detected. Note that if an ID code is already held in the memory area 50, a new ID code is overwritten thereon.

Now, when writing a new ID code to the selective call receiver, or changing the already held ID code to a different ID.
When rewriting to a code, the selective call receiver is the writing device 6.
It is placed within the reach of radio wave signals from 0, preferably nearby. The individual number writing device 60 stores a specific number by the code generator 10 and a new individual number to be written manually from the operating section 14. When the send button 13 is pressed in this state, the code transmitter 11 sends out a specific code and an ID code in which the specific number and individual number are encoded, respectively, from the base station in a format similar to a normal selective call signal. It is transmitted wirelessly.

On the other hand, in the selective call receiver 70, the normal operation of the selective call receiver (
Step 401) In addition, the logic unit 41 checks whether the mode setting switch 90 is pressed (step 402). If the mode setting switch is pressed, the LD code writing mode is set, and the logic unit 41 stops the battery saving operation that was performed during normal operation, and the power control circuit so that power is always supplied to each part of the device. (not shown)
Step 403). When the specific code and ID code arrive from the individual number writing device 60, these codes are received and demodulated by the radio circuit 2 and the decoder circuit 3, and then introduced into the logic unit 41 of the control circuit 40, and this logic unit 41, the specific code is stored in memory area 42
The code is compared with a specific code stored in advance (step 404). If a specific code is detected as a result of this verification, the logic unit 41 writes the new ID code received following the specific code into the memory area 50 (step 405).

Next, the logic unit 41 makes a sound from the speaker 7 to notify the user that the ID code transfer has been completed.
For example, the drive circuit 6 is controlled so that a beep sound is output for one second, but a display to that effect is displayed on the display 80, for example,
The display device 80 is driven to display "Although obtained" (step 4o6).

After this, the process returns to normal operation (step 401).

As described above, in this embodiment, the specific code and the new ID code are sent from the individual number writing device 60 in the same signal form as the selective call signal, and the selective call receiver 70 receives the specific code and the new ID code, thereby receiving the selective call. The ID code stored in the ID code storage area 50 of the receiver 70 can be written while the ID code storage area 50 is still attached to the receiver. Therefore, when writing an ID code, open the lid of the receiver case and remove the ID code storage area 50 as in the conventional case, and then transfer this storage area 50 to an external RO.
There is no need to set the M writer at all, which greatly reduces the effort and time required for writing and increases work efficiency.

As mentioned above, since the identification code is held in the memory area within the microprocessor, the RO for holding the ID code is
There is no need to separately install a memory device such as M.
In view of the current situation where the degree of integration and memory capacity of electronic devices is increasing, this greatly contributes to the miniaturization of devices.

Note that the present invention is not limited to the above embodiments. For example, in the above embodiment, explanation has been given of a case in which the receiver is applied to a receiver that performs only audible display, but as shown in FIG. It may also be applied to a receiver. In this case,
For example, as shown in FIG. 4, the individual number writing device may insert a specific code into the ID code insertion section of one call word, and insert a new ID code into the message code insertion section and send the same.

In this embodiment, the ID code writing mode is set by a switch, but if two points and a selective call receiver are included in FIG. 1 to avoid affecting other receivers, the mode can be set in particular. Alternatively, the specific number code may be detected during normal operation and the ID code may be written. In addition, in this embodiment, 1
Although the present invention is applied to writing one ID code, it is obvious that it can also be applied to writing a group number code for group battery saving. In addition, the signal structure of the specific number, the structure, control procedure, control content, etc. of the individual number code number rewriting control means can be modified in various ways without departing from the gist of the present invention.

As described in detail above, according to the first embodiment of the present invention, when the specific code inserted in the received selective call signal matches the specific code stored in the specific code storage section, the control circuit By writing the ID code received following the specific code into the memory area within the
It is possible to write the ID code without removing the memory device for storing the ID code from the receiver. A call receiver may be provided.

Next, as a second embodiment, a case will be described in which a specific number code and a new individual number code (ID code) are sent from the base station.

FIG. 5 shows a modified configuration of the base station according to the second embodiment.

Referring to FIG. 5, the base station 600 includes a trunk circuit 601 that receives a call request with the number of the called receiver from the selective calling telephone exchange, and a trunk circuit 601 that receives the number of the called receiver from the trunk circuit 601. Memory circuit 6 for storing
It is equipped with 02.

The base station 600 further includes an identification code and identification code generator 603 which generates data bits corresponding to the identification code to be transferred or the called receiver number and their check bits, and which generates empty spaces in the calling word. An idle code generator 6 that generates an idle code shown in FIG.
04, and a preamble word generator 6 that generates a preamble word including a synchronization word and a group designation signal.
05, a timing control circuit 606 and a gate circuit 607 that supply timing signals to the identification code and specific code generator 603.

This gate circuit 607 selectively outputs the signals supplied by the identification code and specific code generator 603, the idle code generator 604, or the preamble word generator 605. The modulator 608 transmits the signal from the gate circuit 607 to the radio channel 6 for transmission.
Modulate to 11. Transmitter 609 transmits the signal provided by modulator 608.

A central processing unit (CPU) supplied to the operation unit 612
) 610 controls the overall operation of base station 60. .

CPU 610 checks whether the called number of a particular group exists in memory circuit 602 when the calling word of that group is sent out. At this time,
If at least the called number is stored in the memory circuit 610, the CPU 610 controls each circuit so that a calling word corresponding to the calling number is sent out as in the conventional system. In this embodiment, the call word is sent five times for each call request.

On the other hand, when CPU 610 receives an instruction to write or rewrite an identification code for a certain selective call receiver from operating unit 612 or from a selective call exchange via trunk circuit 601, it performs the following control.

The CPU 610 is an identification code and specific code generator 60
3, whereby a specific code with an identification code specified via the operating unit 612 or the trunk circuit 601 is generated by the identification code and specific code generator 603.
generated from.

These signals are sent out over the radio channel 611 via the gate circuit 607, the modulator 608 and the transmitter 609 after the transmission of the preamble word corresponding to each group under the control of the CPU 610.

FIG. 6 is a block diagram showing the configuration of a selective call receiver according to a second embodiment of the present invention.

Referring to FIG. 6, a selective call receiver 700 includes a radio (reception) circuit 701 that receives a call signal transmitted from a base station over a radio channel 611, and corrects errors in data bits based on a subsequent check pit. an electrically erasable and programmable read-only memory for storing identification codes and other permanently stored data unique to the selective call receiver;
EEPl? ON) 703, a battery 704 that supplies power to each circuit, and a battery saving circuit 705 that supplies power from the battery 704 to the wireless circuit 701 in accordance with a control signal. Control circuit 706 checks the received call signal and generates a notification signal, and also supplies a control signal to battery saving circuit 705. Clock generator 711 provides a clock signal to the control circuit. The amplifier 708 amplifies the notification signal from the control circuit 706, and the speaker 709 outputs a notification and a buzzing sound in response to the amplified notification signal. A switch 712 is a switch for setting the identification code writing mode.

Next, the operation of the selective call receiver according to this embodiment will be explained in detail with reference to the flowchart of FIG. Although the algorithm is stored layered in EEFROM 703, it may also be stored in the memory area of control circuit 706.

Referring to FIG. 7, when switch 710 is turned on (step 801), each circuit except wireless circuit 701 is supplied with power by battery 704. Control circuit 706
A count value C in the register is set to '0'' (step 802). This count value C indicates how many times the call word to the selective call receiver has been detected. The control circuit 706 outputs a control signal. controls the battery saving circuit 705 by transmitting the
01 is supplied with power from the battery 704 (step 8
03). In radio circuit 701, a synchronization signal is detected. This synchronization signal is checked to determine whether a subsequent group designation signal indicates the group to which the selective calling receiver belongs. The preamble word, consisting of the synchronization signal and the group designation signal, is thus detected by comparing the received group designation number with that stored in memory 303 (step 804).

In response to the detection of the preamble word, the control circuit 706 sets the timer 707 to "0" (step 8).
05), the wireless circuit 701 via the error correction circuit 702
Check the subsequent first call word supplied by . In error correction circuit 702, signal errors contained in data bits are corrected based on subsequent check bits.

Therefore, control circuit 706 is provided with corrected data bits. Control circuit 706 determines whether the subsequent first call word comprises a specific code by comparing the data bits of the call word with the specific code read from EEPROM 70B (step 806).

When the specific code is detected, the control circuit 706 determines whether the switch 712 is operated, that is, whether the ID code writing mode is set (step 817), and determines whether the ID code writing mode is set. If not, the operation of control circuit 706 proceeds to step 809. Further, when determining that the ID code write mode is set, the control circuit 706 writes a new identification (ID) code that is subsequently received into the EEPROM 703 (
step 818). Thereafter, as in the first embodiment, the speaker 7 or the display 80 is driven to notify the user that the ID code has been transferred (step 819).

If the specific code is not detected in step 806 above, the control circuit 706 compares the data bits contained in the received call word with the identification number of the selective call receiver read from the EEPROM 703 bit by bit. checks whether there is a call word directed to the selective call receiver among the received call words (steps 809 and 810). and,
When the data bit contained in the call word matches the identification number, control circuit 706 increments count value C in the register by one and then checks its contents (steps 811, 812).

In this embodiment, the user notification instruction is generated in response to two successive detections of the call word to the selective call receiver. Therefore, if count value C is equal to 2, control circuit 706 generates a notification signal having a predetermined signal frequency for a predetermined period of time. This notification signal is amplified by amplifier 708 and then output as a beep from speaker 709 (step 813). The control circuit 706 then reset the count value C to 0# (
After step 814), the battery saving circuit 706
A control signal is sent to the wireless circuit 701, thereby turning off the power supply from the battery 704 to the wireless circuit 701 (step 81).
5). If the count value C is not equal to 2, the operation of the selective call receiver proceeds to step 815 without instructing notification, and the count value C is reset.

In either case, when a call word to the selected call receiver is first detected, receiver operation proceeds to step 815 without checking for remaining call words. Therefore, power consumption can be saved during the period of checking other call words.

In addition, if there is no call word directed to the selective call receiver among the received call words, the operation of the receiver is performed in step 814 after setting the count value C'0'' to a count value C'0''. Proceed to step 815. The control circuit 706 checks whether the time T1 set in the timer 707 set in step 805 has elapsed (step 816).This time T1 is the period of one frame excluding the group signal. Generally compatible.

When time T1 has elapsed, receiver operation returns to step 803.

According to this embodiment, similarly to the first embodiment, it is not necessary to write the ID code, which greatly reduces labor and time, increasing work efficiency, and also eliminates the need to remove the EEPROM 703. During assembly, it is possible to securely attach the receiver's circuit board to the circuit board by soldering, etc., and as a result, the EEPROM package can be changed from a DIP type to a flat type, and the storage unit itself can be made smaller.As a result, the socket Coupled with this, the receiver can be made smaller. Furthermore, in the above-described wireless embodiment, when rewriting an ID code that has already been written, it is possible to transfer and write the ID code without setting a mode using a switch or the like. In this case, the sending side sends the message in the order of old ID code + special specific code and new ID code, and the receiving side checks whether there is a specific code in the message code sent to its own device, and even if it is a specific code, If the new ID code is continuously received, the old ID code is rewritten.

FIG. 8 shows a schematic configuration of a selective call receiver in a third embodiment of the present invention. In this figure, the same parts as in FIG. 1 are given the same reference numerals and detailed explanations will be omitted.

The selective call receiver of this embodiment includes an ID memory 501 consisting of an EEFROM for storing its own ID code;
It has a write input terminal 91 for externally writing an ID code into the ID memory 501, and further has a control circuit 410 consisting of a microcomputer. This control circuit 410 inputs the received ID code to I
A code matching section 411 compares the ID code of the own device stored in advance in the D memory 501, and when the code matching section 411 detects a call to the own device, a ringing signal is sent to the speaker 7 via the drive circuit 6. A call notification control unit 421 that supplies a call notification to generate a ringing sound, and further includes a write control unit 431
and RAM441. This write control section 431
Is the PI? input to the write input terminal 91? When the output terminal 111 of the external writing device 101 such as an OM writer is connected and the stop switch 81, which is normally used to stop the sound, is operated, the writing mode is set and the ID memory 501 is At the same time as writing control is started, a ringing signal indicating that the writing mode has been set is supplied to the speaker 7 via the drive circuit 6, thereby generating a writing mode setting confirmation sound.

Next, the operation of the receiver configured as described above will be explained according to the control procedure of the control circuit 410 with reference to the flowchart of FIG. Control circuit 4 in call standby state
10, as shown in FIG. 9, repeatedly monitors the occurrence of a call and monitors the connection of the external writing device 101 to the write input terminal 91 in steps 2a and 2b. and,
If the ID code received in this state matches the ID code of the own machine stored in advance in the ID memory 501, it is determined that a call has occurred to the own machine in step 2a, and the process then shifts to call notification control. .

Now, suppose it becomes necessary to change the ID code due to a change in the ownership of the receiver, etc., and the operator uses the output terminal 111 of the external writing device 101 to write to the write input terminal 91 of the receiver.
is connected, the control circuit 410 detects this in step 2b and proceeds to step 2C;
At C, the operation of the stop switch 81 is monitored. In this state, when the operator presses the stop switch 81 after completing the rewriting preparation, the control circuit 410 moves from step 2C to step 2d.
Then, in step 2e, a ringing signal indicating that the write mode has been set is supplied to the speaker 7 via the drive circuit 6. Therefore, the speaker 7 generates a sound confirming the setting of the write mode, and the operator can clearly know from this confirmation sound that the write mode has been set.

After confirming that the writing mode has been set, the operator operates the external writing device 101 and inputs a new ID code into the receiver. Detect in step 2f and step 2g
In this step 2g, the new ID code is introduced, and in step 2h, the RAM 44 in the control circuit 410 is
1 is temporarily stored. When the input of the ID code is completed, the old code stored in the ID memory 501 is written to the new ID code in step 21. When the writing is completed, this is confirmed in step 2j, and then the process goes to step 2. A sound indicating that writing has been completed is generated from the speaker 7, and the state returns to the call standby state. ; In this way, in this embodiment, the ID memory 501 is
FROM, and the receiver is provided with a write input terminal 91 and a write control section 431 so that the ID code stored in the ID memory 501 can be written from outside.
The D memory 501 does not need to be removed from the receiver and reattached when writing the iD code. For example, it can be directly fixed to a printed wiring board in the receiver by soldering or the like.

Therefore, it is possible to use a small ROM, and it is also possible to eliminate the need for a housing space such as a socket for removably mounting the ID memory, and as a result, the receiver can be made smaller. Since the selective call receiver is carried in a pocket or the like, the smaller the receiver, the better. Therefore, the above effect is extremely useful for the selective call receiver. In addition, in this embodiment, a confirmation sound is generated when the rewriting mode is set, so the operator can be clearly informed that the writing mode has been set. It is possible to improve the work efficiency and reliability of workers. In addition, since the confirmation sound is generated from the existing call notification speaker 7, there is an advantage that the receiver does not need to be provided with a new speaker or the like. Further, similar advantages can be obtained by using the existing sound stop switch 81 for setting the write mode.

Note that the present invention is not limited to the above embodiments. For example, if a light-emitting display such as a light-emitting diode is used in addition to a speaker as a call alarm, the light-emitting display may blink to notify that the write mode has been set. . Furthermore, if a message display device is provided, a guidance message indicating that the write mode has been set may be displayed on this display device. Furthermore, the write mode setting instruction may be input by operating other existing switches such as a message display switch in addition to the stop switch. In addition, the structure and control content of the write control means, the means for notifying that the write mode has been set, the type of ID memory, etc. can be modified in various ways without departing from the gist of the present invention.
