Hereinafter, embodiments of the present invention will be described together with illustrated examples.
FIG. 1 is a circuit diagram showing a circuit configuration of an electronic keyboard instrument (for example, an electronic organ).

  As shown in the figure, the electronic keyboard instrument is connected to a CPU 201, ROM 202, RAM 203, panel scan circuit 204a, keyboard scan circuit 205a, sound source 206, and peripheral devices via a system bus 200 (not shown). ) Are connected to each other.

  The system bus 200 is used for transmitting and receiving address signals, data signals, control signals, and the like (signal bus composed of an address bus, a data bus, and a control signal line).

  The CPU 201 is a central processing unit that controls the electronic keyboard instrument, and controls the keyboard scan circuit 205a and the panel scan circuit 204a according to a program stored in the ROM 202, which will be described later. By scanning the mode setting keys 204 and various setting switches (including the upper left button to be described later) and the like, performance information associated with key depression / release of the keyboard 205 is sent to an assignment memory (not shown). Control is performed so that a desired musical tone signal is generated from the sound source 206 according to the assignment processing to the sound source 206, the mode setting of the operation panel 204, various function selection setting switches, and the volume. Further, when the performer is identified, the stored performance setting state (registration data) of the performer is read out and set in each part of the electronic keyboard instrument. is doing.

  The ROM 202 stores a control program for the electronic keyboard musical instrument for the CPU 201 described above, and a program for carrying out the present invention for reading out registration data for each identified performer and making settings in accordance therewith. Read-only memory. In addition, the CPU 201 stores various parameter data that are referred to when generating musical sounds.

  The RAM 203 is a readable / writable memory that temporarily stores data at the processing stage in the program processing in the CPU 201 and stores parameter data that can be edited. In addition, a register, a counter, a flag function, and the like are defined in this RAM as necessary. Furthermore, the performance setting state of the performer can be stored as registration data, and when the performer is identified, the registration data for each performer is read out and set in each part of the electronic keyboard instrument. The storage unit 20 described later according to the present invention is configured.

  The keyboard scan circuit 205a is a circuit that detects key press data generated by the keyboard 205 and sends it out as performance information. As will be described later, the keyboard 205 and the keyboard scanning circuit 205a press the keyboard 205 in a predetermined order to recognize the key depression data as a user ID and identify the player. It can also be used as an identification unit 10 to be described later.

  The performance information from the keyboard scanning circuit 205a is sent to the sound source 206 corresponding to each channel in the performance mode by the CPU 201 referring to the mode setting flag on the RAM 203.

  The panel scan circuit 204a scans each switch on the operation panel 204 in response to a command from the CPU 201, and each switch corresponds to 1 bit based on a signal indicating the open / closed state of each switch obtained by this scan. Create the panel data. Each bit represents, for example, “1” indicating a switch-on state, and “0” indicating a switch-off state. This panel data is sent to the CPU 201 via the system bus 200. This panel data is used to determine whether an on event or an off event of a switch on the operation panel 204 has occurred. Various mode setting flags on the RAM 203 are set by setting the operation panel 204.

  In addition, when the performance setting state for each performer is set, it indicates who the performance setting state is, and there are various mode setting switches and the above-mentioned LCD or LED display for displaying the setting state. is doing. Therefore, the panel scan circuit 204a sends the display data sent from the CPU 201 to the LED display and the LCD on the operation panel 204. Thus, the LED display is turned on / off according to the data sent from the CPU 201, and a message is displayed on the LCD.

  Further, an operation panel 204 is connected to the panel scan circuit 204a. The operation panel 204 has a function of detecting an upper left button to be described later when the configuration of the present invention capable of setting registration is executed in the performance mode.

  The sound source 206 is designed by a sound source LSI, and has a function of generating a musical sound together with a waveform memory (not shown). Here, an arbitrary read signal is generated based on the key depression data input from the keyboard 205, the original waveform data stored in the waveform memory is read based on the read signal, and inter-sample interpolation processing or the like is performed. Then, filter processing, envelope addition processing, etc. are performed to generate and output predetermined waveform data.

  The output of the sound source 206 is input to the D / A conversion circuit 207, converted from digital to analog, amplified by the amplifier 208, and emitted from the speaker 209 to the outside as a musical sound.

  The D / A conversion circuit 207 is a digital-analog converter that converts the digital tone signal generated by the sound source 206 into an analog tone signal.

  The amplifier 208 is a power amplifier that amplifies the analog musical sound signal that has been subjected to analog processing so as to be generated by the speaker 209.

  The speaker 209 is a speaker that emits an analog signal as an audible signal. FIG. 2 is a functional block diagram of a configuration of an embodiment according to the present invention adapted to the electronic keyboard instrument. As shown in the figure, the configuration of the present invention includes an identification unit 10 including a combination of a keyboard 205 and a keyboard scan circuit 205a and the RAM 203 (from a flexible disk to a flexible disk as will be described later). (Including the case where data read by the disk drive 40 is stored in the RAM 203), the storage unit 20 for storing data, and the control unit 30 including the CPU 201.

  Further, the configuration of the present embodiment includes an operation panel 204 for performing various settings of the electronic keyboard instrument, an operator composed of the panel scan circuit 204a, and a flexible disk drive 40 described later.

  Then, the performance setting state of each performer set using the operation panel 204 can be stored in the storage unit 20 as registration data in accordance with a screen display described later. It has become. Further, the flexible disk drive 40 is used as a backup to store the flexible disk, and the registration data is read out as necessary, and the data can be stored in the storage unit 20 again.

  In the above-described configuration, in the configuration of the present embodiment, registration data set by performing various settings of the electronic keyboard instrument by adjusting and setting an operator on the operation panel 204 is passed through the panel scan circuit 204 a and the control unit 30. Thus, the storage unit 20 stores each player. For this purpose, information for identifying the performer is sent to the control unit 30 via the identification unit 10, and the registration data of each performer is stored in the storage unit 20 for each identification information. become. In that case, normally, immediately after the registration data is set, information for identifying the person is input and stored together in the storage unit 20.

  As will be described later, such information corresponds to the configuration of the identification unit 10 and may be biometric identification information unique to each person such as a fingerprint, vein, or iris, or may be generated from the FRID chip. It may be configured to have a receiver that receives a minute radio wave and identifies a player, or may be configured to use key pressing data for pressing a key in a predetermined order as a user ID. .

  Further, when the performer is identified by the identifying unit 10, the control unit 30 reads the identified performer's registration data from the storage unit 20, and accordingly, the sound source 206, the panel scan circuit 204 a and the keyboard. A control command is issued to the scan circuit 205a and the like to change the performance setting state of the electronic keyboard instrument.

  3 to 5 show an embodiment of the configuration of the identification unit 10, and a fingerprint identification device (in FIG. 5, the glass 17 of FIG. It is a configuration provided with only the configuration so that it can be seen from the outside.

  When the player's finger is lightly touched here (glass 17 in FIG. 5), the player's performance setting state is first registered. In other words, the performer sets his / her performance state so far, and displays the screen shown in FIG. 4 on the operation panel 204 using the operator on the operation panel 204.

  If the OK button is touched on this registration screen and the performer's finger is placed on the glass 17, the biometric identification information such as the performer's fingerprint is digitized by the identification unit 10 by the slave CPU 11 described later. Output as information. The controller 30 converts the performance setting state into registration data, and the fingerprint information is stored in the storage unit 20 in association with the registration data.

  On the other hand, if the performer who registered the registration data as described above together with his / her fingerprint information places his / her finger on the glass 17, as shown in FIG. The fingerprint information is output as digitized fingerprint information by a slave CPU 11 described later. Fingerprint information registered in the storage unit 20 in advance together with the player's registration data is searched by the control unit 30, and when the corresponding information is detected, the corresponding registration data is read by the control unit 30. And is set in the sound source 206, the panel scan circuit 204a, and the keyboard scan circuit 205a.

  In this embodiment, as shown in FIG. 3, the identification unit 10 constituted by the fingerprint identification device has a slave CPU 11, ROM 12, RAM 13, interface 14, light emitting diode 15, light receiving element on a bus different from that shown in FIG. 16 and glass 17. That is, according to the control unit program read from the ROM 12, the slave CPU 11 causes the light emitting diode 15 to emit light, captures the shadow of the finger passing through the glass 17 with the light receiving element 16, and acquires the fingerprint information. The data is sent as shadow data to the control unit 30 via the interface 14.

  The control unit 30 that has received the shadow data together displays a message as shown in FIG. 4 on the panel 204 and touches the OK button, together with the above-described shadow data that identifies the operator. The registration data set at that time is associated and stored in the storage unit 20.

  On the contrary, when the person who registered the shadow data of the fingerprint plays next with the electronic keyboard instrument, the finger on which the person has registered the shadow is lightly touched on the glass 17 as shown in FIG. Thus, the shadow of the fingerprint is input to the light receiving element 16, and the slave CPU 11 converts it into shadow data, which is transferred to the control unit 30 via the interface 14.

  Then, the control unit 30 searches the storage unit 20 based on the shadow data, reads out the performer's registration data stored in the storage unit 20 from the matched shadow data, and according to that, the sound source 206, a control command is issued to the panel scan circuit 204a, the keyboard scan circuit 205a, etc., and the performance setting state of the electronic keyboard instrument is changed.

  Of course, in addition to fingerprints, biometric identification information unique to each person such as veins or irises can be used, and an identification device corresponding to them can be used.

  FIGS. 6 to 8 also show other examples of the configuration of the identification unit 10. In the operation panel 204, only the RFID communication unit (the antenna 18 is shown in FIG. 8 as will be described later). And a card attached to the person to be identified.

  By bringing a card provided with an FRID chip 18a on which a performer can register his / her identification information close to the antenna 18 of the RFID communication unit, the performance setting state of the performer is first registered. That is, the performer sets his / her performance state so far, and displays the screen shown in FIG. 7 on the operation panel 204 by using the operator on the operation panel 204.

  If the OK button is touched on this registration screen and the player's card is brought close to the antenna 18 of the RFID communication unit, arbitrary ID information is generated as identification information of the player by the slave CPU 11 described later. Similarly, the slave CPU 11 converts the identification information into an encrypted signal by an arbitrary encryption processing method, and transmits the encrypted signal to the RFID chip 18 a of the card via the antenna 18. At the same time, the identification information is output to the control unit 30 by the slave CPU 11. Then, the controller 30 converts the performance setting state into registration data, and the identification information is stored in the storage unit 20 in association with the registration data.

  On the other hand, if the performer who has registered the registration data as described above together with his / her identification information brings the card he / she holds close to the antenna 18 as shown in FIG. Is received by the antenna 18, and the encryption signal corresponding to the identification information of the performer is decrypted by the slave CPU 11, which will be described later, and output as corresponding identification information. The Then, the identification information registered in the storage unit 20 in advance together with the registration data of the performer is searched by the control unit 30, and when the corresponding information is detected, the corresponding registration data is read by the control unit 30. And is set in the sound source 206, the panel scan circuit 204a, and the keyboard scan circuit 205a.

  The card includes a FRID chip 18a that newly stores an encrypted signal of each performer when the encrypted signal is registered, and can transmit the encrypted signal on radio waves when the encrypted signal is not registered. ing.

  The communication unit communicates with the FRID chip 18a using a minute radio wave, and transmits / receives an encrypted signal stored in the chip or stored. That is, as shown in FIG. 6, a slave CPU 11, a ROM 12, a RAM 13, an interface 14, and an antenna 18 connected to the interface 14 are provided on the same bus as described above.

  Again, when registering registration data for each performer in accordance with the control unit program read from the ROM 12, the slave CPU 11 provides unique identification information (who may not be specified) for each registration operation. Then, it is encrypted and transmitted to the FRID chip 18a through the interface 14 and the antenna 18. At the same time, the identification information is sent to the control unit 30 via the interface 14. At this time, the RFID chip 18a is set in the encrypted signal registration state and stores the received encrypted signal in a data storage unit (not shown).

  On the other hand, the control unit 30 that has received the identification information together displays a message as shown in FIG. 7 on the panel 204 and touches the OK button, together with the identification information that identifies the operator. Then, the registration data set at that time is associated and stored in the storage unit 20.

  On the contrary, when a person who holds the card in which the encrypted signal is registered plays the electronic keyboard instrument next time, as shown in FIG. Then, the encrypted signal transmitted therefrom is received by the communication unit via the antenna 18, and the slave CPU 11 decrypts it and converts it into digital identification information, which is then sent to the control unit 30 via the interface 14. Forward.

  Then, the control unit 30 searches the storage unit 20 based on the identification information, reads out the performer's registration data stored in the storage unit 20 from the matched identification information, and according to that, the sound source 206, a control command is issued to the panel scan circuit 204a, the keyboard scan circuit 205a, etc., and the performance setting state of the electronic keyboard instrument is changed.

  9 to 11 show another example of the configuration of the identification unit 10, and a user ID input button for identifying a user ID provided as an operator on the operation panel 204, And a user ID input unit composed of a keyboard 205.

  When the performer is able to set his / her performance setting state for the electronic keyboard instrument, the user ID input button (shown by 204 in FIG. 11) is pressed to set the registration data registration state. At that time, the player uses the keyboard 205 to press the keys 205 in the order determined by the player, so that the key pressing information becomes the player identification information, and the performance setting state is registered as the registration data. Can be registered. That is, the performer has set his performance state so far and uses the user ID input button on the operation panel 204 to display the screen shown in FIG. 10 on the operation panel 204.

  If the user ID input button is pressed again on this registration screen and the player presses the keyboard 205 in the order determined by the player himself, the key pressing information for identifying the player by the identifying unit 10 is the slave to be described later. It is output as identification information by the CPU 11. The control unit 30 converts the performance setting state into registration data, and the identification information is stored in the storage unit 20 in association with the registration data.

  On the other hand, a player who has registered the registration data as described above together with his / her identification information presses a user ID input button (shown by 204 in FIG. 11) as shown in FIG. In the ID input state, when the player presses the keyboard 205 in the order that the performer remembers himself / herself, the identifying unit 10 identifies the performer's identification information (keypress information) corresponding to the depressed key information. May be output by the slave CPU 11 described later. Then, the identification information registered in the storage unit 20 in advance together with the registration data of the performer is searched by the control unit 30, and when the corresponding information is detected, the corresponding registration data is read by the control unit 30. And is set in the sound source 206, the panel scan circuit 204a, and the keyboard scan circuit 205a.

  In the present embodiment, as shown in FIG. 9, the identification unit 10 uses the configuration already in FIG. In other words, the operation panel 204 having the user ID input button including an operator and its panel scan circuit 204a, and the keyboard 205 and keyboard scan circuit 205a for inputting the key depression information are configured. The key pressing information captured by the keyboard scanning circuit 205a is sent to the control unit 30 as identification information.

  The control unit 30 that has received the key pressing information displays a message as shown in FIG. 10 on the panel 204 at that time, and the user ID input button is pressed to identify the operator. At the same time, it is stored in the storage unit 20 in association with the registration data set at that time.

  On the contrary, when the person who registered the key pressing information next plays with the electronic keyboard instrument, the person presses the keyboard 205 in the order that he / she remembers as shown in FIG. The key depression information is transferred to the control unit 30 via the keyboard scan circuit 205a.

  Then, the control unit 30 searches the storage unit 20 based on the key press information as identification information, and registers the performer stored in the storage unit 20 from the matched identification information. Data is read out, and a control command is issued to the tone generator 206, the panel scan circuit 204a, the keyboard scan circuit 205a, and the like accordingly, and the performance setting state of the electronic keyboard instrument is changed.

  12 to 14 are flowcharts of the main routine, the event processing included in the processing therein, and the resist development processing included in the processing in the event processing in the electronic keyboard instrument.

  First, the main routine shown in FIG. 12 will be described. As shown in the figure, when the electronic keyboard instrument is turned on, initialization is performed (step S100), and it is checked whether an event has occurred (step S102).

  If an event has occurred (step S102; Y), event processing is performed (step S104), and then time-lapse processing such as vibrato processing is performed (step S106).

  On the other hand, if no event has occurred (step S102; N), the process proceeds to time-dependent processing (step S106). After this time-lapse process, the process returns to step S102 and the above process is repeated.

  FIG. 13 shows a process flow of the event process in step S104 of FIG. In this event process, it is checked whether or not identification information including ID information from the identification unit 10 has been received (step S200). If identification information has been received (step S200; Y), a resist development process is performed. (Step S202).

  If the identification information has not been received (step S200; N), it is next checked whether or not key pressing information has been input (step S204). If key pressing information has been input (step S204; Y), key pressing processing such as sound generation processing / mute processing is performed (step S206). That is, a musical tone is generated based on the key depression information.

  On the other hand, if the key pressing information is not input (step S204; N), it is checked whether or not there is panel operation input information (step S208). If there is input information for panel operation (step S208; Y), panel processing such as tone selection and volume adjustment is performed (step S210).

  On the other hand, if there is no input information for panel operation (step S208; N), system setting (master tune, etc.), other processing such as MIDI reception is performed (step S212), and this event processing is completed. Transition to routine aging.

  FIG. 14 shows a process flow of the resist development process in step S202 of FIG.

  First, A is input to the top address & RBANK [ID] of the registration data bank of the bank number ID (step S300). Then, B is input to the start address & RRMEM of the registration data memory that can be sounded (currently in use) (step S302). Further, N is input to the size RgSize of registration data for one person (step S304).

  Thereafter, 0 is set in the loop counter i (step S306), and the contents of the address A are transferred to the address B (step S308).

  Next, the address A is incremented (step S310), the address B is further incremented (step S312), and then the loop counter i is incremented (step S314).

  Then, it is checked whether or not the loop counter i has reached N, that is, the size RgSize of the registration data for one person (whether or not the data transfer for one person has been completed) (step S316). When the loop counter i is not N (step S316; N), the process returns to the process of step S308 and the above process is repeated. On the contrary, if the loop counter i is N (step S316; Y), the resist development process is ended there, and the process proceeds to the time-dependent process of the main routine.

  FIGS. 15 to 17 are main routines of the slave CPU 11 in the identification unit 10 when the identification unit 10 is configured by the fingerprint identification device of FIGS. 3 to 5, event processing included in the processing therein, It is each flowchart of the image recognition process similarly included in the process in an event process.

  In the main routine of the slave CPU 11 in FIG. 15, each device configuration of the identification unit 10 is similarly initialized (step S400), and it is checked whether an event has occurred (step S402).

  If an event has occurred (step S402; Y), event processing is performed (step S404), and the process returns to step S402 to repeat the above processing.

  On the other hand, if no event has occurred (step S402; N), the process returns to step S402.

  FIG. 16 shows a process flow of the event process in step S404 of FIG. In this event processing, since the fingerprint image is output as fingerprint information from the identification unit 10, it is first checked whether or not the image information has been acquired (step S500). If the image information has been acquired (step S500; Y), an image recognition process is performed (step S502).

  On the other hand, if the image information has not been acquired (step S500; N), other processing is performed (step S504).

  FIG. 17 shows a processing flow of the image recognition processing in step S502 of FIG. In this image recognition process, a fingerprint is recognized and compared with other registered fingerprint information.

  Therefore, first, the fingerprint image of the acquired fingerprint information is binarized (step S600).

  Then, the registered fingerprint information (comparison target registered fingerprint information) to be compared is acquired from the storage unit 20 by the control unit 30 (step S602).

  The error s is set to the maximum value Max (step S604), the rotation angle d is set to -10 degrees (step S606), the scale v is set to 85% (step S608), and registration to be compared is made accordingly. Fingerprint information is set in that state.

  Then, while the obtained image of the binary fingerprint information is reduced in scale (step S610), the comparison processing of both information is performed as follows.

  That is, the acquired binary fingerprint image information is compared with the registered comparison target registered fingerprint information to be compared, and whether the measurement error is smaller than the set error s (initially the maximum value Max). It is checked whether or not (step S612).

  When the measurement error is smaller than the set error s (step S612; Y), the measurement error is set as the error s (step S614). Conversely, if the measurement error is not smaller than the set error s (step S612; N), the process jumps to the next step S616.

  Then, it is checked whether or not the measurement error is smaller than the minimum error value sMin set to a predetermined threshold value (step S616). If the measurement error is smaller than the minimum error value sMin set to the predetermined threshold value (step S616; Y), the acquired binary fingerprint image information and the registered comparison target registered fingerprint information to be compared are obtained. If they match, the user ID corresponding to the registered fingerprint comparison image information is sent (step S618). This user ID is received by the control unit 30 in step S200 of FIG.

  On the other hand, if the measurement error is not smaller than the minimum error value sMin set to the predetermined threshold (step S616; N), the scale v is incremented (step S620), and the scale v is further set to 115%. It is checked whether or not (step S622).

  If the scale v is not set to 115% (step S622; N), the process returns to step S610, and the comparison process of both information is repeated as described above while the image of the binary fingerprint information is rotated. It is.

  Conversely, if the scale v is just set to 115% (step S622; Y), the rotation angle d is incremented (step S624), and it is further checked whether the rotation angle d is set to +10 degrees. (Step S626). If not set to +10 degrees (step S626; N), the process returns to step S608, the scale v is set to 85% again, and the above comparison processing is repeated.

  If the rotation angle d is just set to +10 degrees (step S626; Y), it is necessary to remove the comparison target registered fingerprint information from the search target and acquire the next comparison target registered fingerprint information. Therefore, it is checked whether or not the current comparison target registered fingerprint information is the last image information (step S628). If it is not the last (step S628; N), the process returns to step S602 and a new comparison is made. The target registered fingerprint information is acquired, and the above processing is repeated.

  On the other hand, if it is the last comparison target registered fingerprint information (step S628; Y), the image recognition process ends (if there is no comparison target registration fingerprint information to be verified, the process returns without sending a user ID).

  If it is determined that the error between the binary fingerprint information and the comparison target registered fingerprint information is smaller than the minimum error value sMin while repeating the above comparison processing, the two information are registered as coincident as described above. The user ID corresponding to the fingerprint comparison image information is transmitted (step S618), and the user ID is received by the control unit 30 in step S200 of FIG.

  18 to 20 show the main routine of the slave CPU 11 in the RFID communication unit when the identification unit 10 is composed of a card having the RFID chip 18a shown in FIGS. 6 to 8 and the RFID communication unit. It is each flowchart of the event process included in the process of the inside, and the decoding process similarly included in the process in an event process.

  In the main routine of the slave CPU 11 in FIG. 18, each device configuration of the identification unit 10 is similarly initialized (step S700), and it is checked whether an event has occurred (step S702).

  If an event has occurred (step S702; Y), event processing is performed (step S704), and the process returns to step S702 to repeat the above processing.

  On the other hand, if no event has occurred (step S702; N), the process returns to step S702.

  FIG. 19 shows a process flow of the event process in step S704 of FIG. In this event process, since the encryption signal is transmitted from the RFID chip 18a, it is checked whether or not the encryption signal is received via the antenna 18 (step S800).

  If the encrypted signal is received via the antenna 18 (step S800; Y), decryption processing is performed (step S802). On the contrary, if the encryption signal is not received via the antenna 18 (step S800; N), other processing is performed (step S804).

  FIG. 20 shows a processing flow of the decoding process in step S802 of FIG. This decoding process is decoded as follows as an example. That is, the received analog signal is digitized (step S900). Then, it is converted into a word in units of bytes or in units of several bytes (step S902), and a sentence is extracted from the word (step S904).

  Further, the above-described sentence is decrypted with the decryption key (private key) (step S906). What has been decrypted is the user ID itself, and a search is made as to whether the user ID is stored in the storage unit 20 (step S908).

  When the user ID is sent from the storage unit 20, the user ID is received by the control unit 30 in step S200 of FIG.

  When the processing cannot be performed in each of these steps (incorrect), the processing of each step is ended there.

  According to the configuration of the present embodiment as described above, when a player is identified by the identifying unit 10, the control unit 30 reads the identified player's registration data from the storage unit 20, and Accordingly, the performance setting state of the electronic keyboard instrument is changed. Therefore, for example, even when a performer is switched and a performance is performed using the same electronic keyboard instrument at a concert venue or the like, the performer is immediately identified and the performance setting state for each performer is immediately displayed. Correspondence becomes possible.

  It should be noted that the electronic musical instrument of the present invention is not limited to the illustrated examples described above, and it is needless to say that various modifications can be made without departing from the scope of the present invention.

  The configuration of the electronic musical instrument of the present invention is not limited to a musical instrument, for example, when a plurality of drivers drive in one car, the height of the steering wheel, the height of the driver's seat, It can be used to change the setting state of the driver's seat such as the movement in the front-rear direction and the inclination of the entire seat to a state suitable for each time each driver is identified.
