The processing operation is comprehensively controlled in cooperation with the program.

  The control unit 11 has modes A, B, and C as sound modes. When an erase operation is performed by the eraser 22, the sound mode is repeatedly switched in the order of A → B → C in conjunction with the erase operation. Modes A and B are modes in which motif sounds (referring to timbres and tones of sounds for one phoneme) or sound are output, and mode C is a mode in which melody music is output. There are three types of melody music in mode C, and which melody music is to be output can be selected by operating the melody button 25.

  In the sound output process, when the characters 3a to 3e existing in the communication range are detected by the reader 16 and their IDs are read out, the currently set sound mode and the read-out sound mode are read based on the character table 131 of the ROM 13. The sound or melody music corresponding to the ID is discriminated, and the sound information is read from the ROM 13 and output by the speaker 15. When a plurality of characters 3a to 3e are detected, sounds or melody music corresponding to the IDs of the characters 3a to 3e having a higher priority are output based on the priority information set in the character table 131. . If a plurality of characters 3a to 3e are detected when the sound mode is set to mode C, the sound corresponding to the combination of the IDs of the plurality of characters 3a to 3e based on the combination table 132 of the ROM 13 is detected. The melody music sound information played in accordance with the output condition is read from the ROM 13 and output from the speaker 15.

  In the case of melody music, the sound information of the music corresponding to the pressed melody button 25 is read from the ROM 13, and the sound set in the mode C for each character 3a to 3e based on the sound information of the music. The sound information obtained by reconstructing the music is generated, and the speaker 15 outputs the sound based on the sound information.

  In addition, when the characters 3a to 3e are not detected by the reader 16 within a predetermined time (in this embodiment, 5 minutes), or after the characters 3a to 3e are once detected, the characters 3a to 3a are newly detected within the predetermined time. If 3e is not detected, the sound information of the announcement sound corresponding to each case is read from the ROM 13 and output by the speaker 15, and then the power is turned off (turned off).

  The RAM 12 forms a work area for temporarily storing various programs executed by the control unit 11 and data related to these programs.

  In addition to the system program, the ROM 13 stores a control program such as a sound output processing program, data processed by each program, and the like.

The ROM 13 is a storage unit that stores sound information such as motif sounds, voices, and melody music corresponding to each of the sound modes A, B, and C, and stores a character table 131 and a combination table 132.
The character table 131 is a table that defines identification information (hereinafter referred to as ID) unique to each character 3a to 3e and the type of sound output from the speaker 15 corresponding to each character 3a to 3e. In the character table 131, as shown in FIG. 3, when a sound is output in association with information of a character name (for example, “ambulance”) and ID (for example, number “011”) set for the character. Priority level of sound, type of sound output in mode A (for example, motif sound such as “Peepy Peep”), type of sound output in mode B (for example, “Ambulance passes”) , A motif sound such as “Concon”), and information on the type of sound output in the mode C (for example, a motif sound such as “Poyon” and a tone color such as “Taiko”) are set.

  The combination table 132 is a table that defines melody music output conditions according to the combination of the detected characters 3a to 3e when a plurality of characters 3a to 3e are detected in the mode C. In the combination table 132, as shown in FIG. 4, the characters 3a to 3e are set in the mode C according to the combinations of the IDs of the characters 3a to 3e indicated by rows and the IDs of the characters 3a to 3e indicated by columns. The conditions for how the ensemble is played according to the type of sound being set are set. For example, when a “boy” character 3e and a “girl” character 3c are detected and two IDs “051” and “052” are read out, IDs “051” and “052” in the example of FIG. As the output condition corresponding to the combination of, a condition for outputting “main melody” by the type of sound corresponding to the “boy” character 3e and “sub-melody” by the type of sound corresponding to the character 3c of the “girl” is set. ing. Therefore, at the time of output, the melody music played with the output conditions is output.

  The operation unit 14 includes the power button 24 and the melody button 25 illustrated in FIG. 1, and outputs an operation signal corresponding to the operated button to the control unit 11.

  The speaker 15 is sound output means for outputting sound based on sound information such as motif sound, sound, melody music, etc. input from the control unit 11.

  The reader 16 is a reading means that detects each character 3a to 3e existing in the communication range by communicating with the IC tag 30 built in each character 3a to 3e, and reads the ID from the IC tag 30. is there. Note that a reader / writer may be applied instead of the reader so that data can be written to the IC tag 30.

FIG. 5 shows a configuration of the reader 16 of the main body 2 and the IC tags 30 of the characters 3a to 3e.
As shown in FIG. 5, the reader 16 on the main body 2 side includes a transmission / reception unit 161 and an antenna an1. On the other hand, the IC tag 30 on the character 3a to 3e side includes an antenna an2, a transmission / reception unit 31, and an IC (Integrated Circuit) 32, and an LED 33 and a switch circuit 34 are connected to the IC tag 30 depending on the character. As a transmission method between the reader 16 and the IC tag 30, various transmission methods such as an electromagnetic coupling method, an electromagnetic induction method, and a radio wave method can be applied. In this embodiment, an example in which the electromagnetic coupling method is applied will be described. To do.

First, each part of the reader 16 will be described.
As shown in FIG. 6, the antenna an <b> 1 of the reader 16 is a loop coil antenna and is arranged so as to surround the screen periphery of the magnetic display 21, and the characters 3 a to 3 e existing within the communication range from the magnetic display 21. The IC tag 30 is detected, and electromagnetic waves are transmitted / received to / from the antenna an2 of the IC tag 30. The communication range is preferably set so that the characters 3a to 3e are detected only when the characters 3a to 3e are in contact with or almost in contact with the magnetic display 21.

  The transmission / reception unit 161 modulates various control signals input from the control unit 11 to generate an electromagnetic wave, and transmits the electromagnetic wave to the IC tag 30 via the antenna an1. When receiving an electromagnetic wave from the IC tag 30 via the antenna an1, the electromagnetic wave is demodulated and the demodulated signal is output to the control unit 11.

Next, each part of the IC tag 30 will be described.
The antenna an2 is a loop coil antenna similar to the antenna an1, and transmits and receives electromagnetic waves to and from the antenna an1. While the electromagnetic wave is being transmitted and received, current is generated by electromagnetic induction in the antenna an2. With this current, power is supplied to each part of the IC tag 30, and when the LED 33 is connected, the generated current flows to the LED 33, and the LED 33 is lit. Conversely, while the antenna an2 is not transmitting or receiving electromagnetic waves, no current is generated, so the LED 33 is turned off.

  The transmission / reception unit 31 demodulates the electromagnetic wave received from the reader 16 via the antenna an2, outputs the demodulated signal to the IC 32, modulates the control signal input from the IC 32, generates the electromagnetic wave, and sets the antenna an2 To the reader 16.

  The IC 32 includes a CPU, a memory, and the like. When a demodulated signal is input from the transmission / reception unit 31, the CPU reads data such as an ID from the memory and writes other data based on the demodulated signal.

As shown in FIG. 7A, an LED 33 is connected to the IC tag 30 configured as described above in a character 3b that simulates a car, and a switch circuit 34 is included in a character 3b that simulates a hammer as shown in FIG. 7B. It is connected.
The LED 33 is a light emitting unit that emits light while communication is performed in the antenna an1 and a current generated by electromagnetic induction flows.

  The switch circuit 34 outputs to the IC tag 30 a switch signal for identifying the placement state of the hammer (which surface of the hammer (one surface is the X surface and the other is the Y surface) is located above). . When the character 3a is placed in a state where the Y surface of the hammer is on the top, the switch circuit 34 is in an OFF state because the switch is separated at the contact point by gravity. On the other hand, when the character 3a is placed in a state in which the X plane of the hammer is on, the switch comes into contact with the contact point, so that the switch 3 is turned on, and this switch signal (ON or OFF) is output to the IC tag 30. . The IC tag 30 of the character 3a stores two IDs corresponding to the X plane and the Y plane. When a switch signal is input from the switch circuit 34, the IC 32 analyzes the switch signal, and the ON signal In this case, it is determined that the X plane is up, and the ID corresponding to the X plane is read from the memory.

Next, the operation in the magnetic display device 1 will be described.
FIG. 8 is a flowchart for explaining sound output processing executed by the magnetic display device 1.
In the sound output processing shown in FIG. 8, it is first determined whether or not the characters 3a to 3e are detected in the main body 2 (step S1). If the characters 3a to 3e are not detected (step S1; N) and five minutes have passed without being detected (step S2; Y), an announcement sound such as “Baibai” is output from the speaker 15, and then the power is turned on. It is automatically turned off (step S3), and this process is terminated.

  On the other hand, when the characters 3a to 3e enter the communication range of the reader 16 of the main body 2 and the characters 3a to 3e are detected (step S1; N), the reader 16 sets the ID from the IC tag 30 of the characters 3a to 3e. Read (step S4). Next, it is determined whether or not there are a plurality of read IDs (step S5). If any one of the characters 3a to 3e is placed on the magnetic display 21 by the user and the ID read by the reader 16 is singular (step S5; N), the process proceeds to step S6. On the other hand, when a plurality of characters 3a to 3e are placed on the magnetic display 21 and the read IDs are plural (step S5; Y), the process proceeds to step S21 shown in FIG.

First, a case where the read ID is singular will be described.
In step S4, it is determined whether the currently set sound mode is mode A, B, or C (step S6). When the currently set sound mode is mode A or B (step S6; modes A and B), it corresponds to mode A or mode B and corresponds to the read ID based on the character table 131. Sound is output from the speaker 15 (step S7).

  For example, when the “ambulance” character 3a is placed on the magnetic display 21 and its ID “011” is read out, in the example of the table shown in FIG. In the case of "Poppy Pippo", the message sound of "Ambulance passes" is repeatedly output from the speaker 15 in the case of Mode B. In the case of the “hammer” character 3a, the ID read from the IC tag 30 differs depending on whether the surface in contact with the magnetic display 21 is the X surface or the Y surface. Different types of sounds are output depending on the placement method.

  Next, it is determined whether or not a predetermined time (here, 10 seconds) has elapsed since the characters 3a to 3e were detected (step S8), and when 10 seconds have not elapsed (step S8; N). Returning to step S7, sound output is continued until 10 seconds have elapsed. When 10 seconds have elapsed (step S8; Y), the sound output from the speaker 15 is stopped (step S9), and the process proceeds to step S12.

  On the other hand, when it is determined in step S6 that the currently set sound mode is mode C (step S6; mode C), it is determined whether or not the melody button 25 is pressed (step S10). When the melody button 25 is pressed (step S10; Y), the melody music corresponding to the pressed melody button 25 is heard from the speaker 15 by the sound corresponding to the ID read in mode C based on the character table 131. (Step S11).

  For example, when the ID “053” of the character 3d of “chick” is read and the melody button 25 of the music 1 is pressed, the motif sound of “piyo” is set in mode C in the example of the table shown in FIG. Therefore, the melody music which performed the music 1 with this motif sound is output from the speaker 15. When one piece of melody music is output, the process proceeds to step S12. On the other hand, if the melody button 25 has not been pressed (step S10; N), the process of step S11 is omitted and the process proceeds to step S12.

Next, the case where it is determined that there are a plurality of IDs read in step S5 will be described from step S21 shown in FIG.
In step S21, the currently set sound mode is determined. When the currently set sound mode is mode A or B (step S21; modes A and B), based on the character table 131, among the plurality of detected characters 3a to 3e, the higher priority character 3a to 3a. A sound corresponding to the ID of 3e is output from the speaker 15 (step S22).

  For example, if an “ambulance” character 3b and a “girl” character 3c are placed on the magnetic display 21, the “ambulance” character 3b is “girl” in the example of the table shown in FIG. Since it has a higher priority than the character 3c, only the sound corresponding to the "ambulance" character 3b ("Peepy Peep" motif sound in mode A, message voice of "Ambulance passes" in mode B) Is output.

  Next, it is determined whether or not 10 seconds have elapsed since the characters 3a to 3e were detected (step S23). If 10 seconds have not elapsed (step S23; N), the process returns to the process of step S22 to generate a sound. When the output is continued and 10 seconds have elapsed (step S23; Y), the sound output is stopped (step S24), and the process proceeds to step S10 shown in FIG.

  On the other hand, if it is determined in step S21 that the currently set sound mode is mode C (step S21; mode C), it is determined whether or not the melody button 25 has been pressed (step S25). When the melody button 25 is pressed (step S25; Y), the melody button 25 corresponds to the pressed melody button 25 under the output condition corresponding to the combination of the IDs of the plurality of characters 3a to 3e detected based on the combination table 132. The melody music on which the music is played is output from the speaker 15 (step S26).

  For example, if a “girl” character 3c and a “chick” character 3d are placed on the magnetic display 21, the “boy” character 3e is “main melody”, “ Since the “girl” character 3c is set to “sub-melody”, the main melody is set in mode C corresponding to the character 3c, and the main melody is set in the motif sound “ton” set in mode C corresponding to the character 3e. The melody music which played the sub melody with the motif sound “polon” is output from the speaker 15. When one melody music is output, the process proceeds to step S12 shown in FIG.

  In step S12, it is determined whether or not characters 3a to 3e are newly detected. When the characters 3a to 3e are newly placed on the magnetic display 21 and detected (including the case where the characters 3a to 3e already placed are once separated from the magnetic display 21 and placed again). S12; Y), the process returns to step S4, and the sound corresponding to the ID of the detected characters 3a to 3e is output. On the other hand, when the characters 3a to 3e are not newly detected (step S12; N), it is determined whether or not 5 minutes have passed since the previous detection (step S13).

  If 5 minutes have not elapsed since the previous detection (step S13; N), the process returns to step S12, and if 5 minutes have elapsed (step S13; Y), the announcement sound “let's clear up” is heard from the speaker. After the output from 15, the power is automatically turned off (step S14), and this process is terminated.

  As described above, according to this embodiment, each of the characters 3a to 3e includes the IC tag 30 in which a unique ID is stored, and the IC tag 30 is placed on the magnetic display 21 on the main body 2 side. The characters 3a to 3e are detected, their IDs are read out, and sounds corresponding to the IDs are output. Therefore, not only can the figures be drawn by the characters 3a to 3e, but an auditory change can be brought along with the drawing, and the user's interest can be increased.

  Further, by connecting the LED 33 to the IC tag 30, the LED 33 can be turned on while the IC tag 30 and the main body 2 are communicating. Thereby, an optical visual effect can be obtained and the user's interest can be further attracted.

  Further, two IDs are set for one character 3a and stored in the IC tag 30, and a switch circuit 34 that outputs an ON / OFF switch signal according to the placement state of the character 3a is connected to the IC tag 30; The ID of the character 3a is switched based on the switch signal. Thereby, the sound corresponding to each ID can be switched and output. Therefore, even one character 3a can output different types of sounds by changing its placement state, and does not bore the user.

  In addition, since the priority order of sound output is set for each character 3a to 3e, confusion of output sound can be prevented even when a plurality of characters 3a to 3e are detected simultaneously.

  Furthermore, since the melody music output conditions are set according to the combinations of the characters 3a to 3e, when a plurality of characters 3a to 3e are placed on the magnetic display 21, the combinations of the characters 3a to 3e are determined. The melody music that was played can be output. Therefore, by changing the combination of the characters 3a to 3e, the user can enjoy various melody music played in a plurality of parts.

  In addition, since a plurality of sound modes are set for each character 3a to 3e, by switching the sound mode, various kinds of sounds can be output, and the user is not bored. Furthermore, since the sound mode is switched in conjunction with the erase operation of the eraser 22, the sound mode can be switched without the user performing a mode switching operation, and the burden on the user's operation can be reduced. This is particularly effective when the user is an infant who is difficult to operate according to the method of use.

  Further, when the characters 3a to 3e are not detected within a predetermined time, or when the characters 3a to 3e are not newly detected even after the predetermined time has elapsed after the characters 3a to 3e are detected, the power is turned off. Therefore, when the non-use time is long, the power is automatically turned off to save power.

  In the above-described embodiment, an example in which the melody music that has been played is output by a combination of the characters 3a to 3e has been described. However, the present invention is not limited to this. of the case, after the output of the voice message of "boy" in the voice of "Hello", etc. to output a voice message of "girl" in the voice of "are doing well?", conversational speech in accordance with the combination of character 3a~3e Is set in the combination table 132, and the conversation voice may be output. Thereby, it can be shown as if the conversation was performed between the characters 3a to 3e, and the user's interest can be drawn. Further, since different conversational voices are output depending on the combination of the characters 3a to 3e, the sound output can be changed, and the user is not bored.

  Further, the magnet of the “boy” character 3e is formed in the shape of the number “1”, the magnet of the character “c” of the “girl” is formed in the shape of the number “2”, and the character 3c is combined by combining the characters 3c and 3e. It is also possible to have an addition mode for outputting a voice that answers the sum “3” obtained by adding the numbers “1” and “2” of 3e. Thereby, intelligence can be improved while playing. In addition, it is good also as not only adding but performing simple arithmetic according to the combination of each character 3a-3e.

  Moreover, although this embodiment demonstrated the example which applied the character 3a-3e which is a stamp as a toy body provided with the IC tag 30, it is not restricted to this, A simple figure may be sufficient, and other toys It may be.
