Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument having a main body mounted with component devices such as a keyboard and a sound source, and more particularly, a component device selected from a plurality of grades can be mounted. The present invention relates to an electronic musical instrument whose grade can be changed.

  In general, in order to meet the needs of a wide range of consumers, there are multiple types of models with different grades, from high-performance, high-priced upper-grade models to low-priced, low-performance lower-grade models, for electronic musical instruments such as electronic organs. Are often provided. As such an electronic organ, for example, one manufactured and sold by the present applicant under the name of “Electone (registered trademark)” is known. When developing such an electronic musical instrument, it would be costly to develop and manufacture each model independently, so the parts that can be shared between the models would be common, and different component devices would be shared according to the functions. The method of attaching to a part is adopted. By adopting such a method, the electronic musical instrument can be upgraded without replacing the common parts by replacing the lower-grade model component devices with the corresponding higher-grade model component devices. Is also possible.

  However, when such an upgrade is performed, there is a problem of updating the control program. Regarding this point, the CPU or the like constituting the control unit can be used in the same part in many cases because the same hardware can be used even if the grade is different. For example, in an electronic musical instrument manufactured as a lower grade model, the control unit naturally performs a control operation using a control program for controlling the common part and each component device of the lower grade model. At this time, even if only the component device is replaced with the higher-grade model, the control unit cannot control a new component device if the control program used for control remains unchanged. Therefore, at the time of upgrading, it is necessary to rewrite the control program or exchange a program ROM for storing the control program.

As means for solving such a problem, in Patent Document 1, a control program for causing an electronic musical instrument to function as an upper grade model and a control program for causing an electronic musical instrument to function as a lower grade model are stored in a ROM. Describes a configuration in which the function of which model is operated is set by an external DIP switch.
With this configuration, when the electronic musical instrument is upgraded by replacing the component device, the control program is switched by changing the setting of the dip switch according to this, and the control unit controls the replaced component device. You can do it.
JP-A-11-73185 (paragraphs 0024 to 0026)

However, in the configuration described in Patent Literature 1, it is necessary to change the switch settings at the time of upgrading, so that there is a problem that the electronic musical instrument does not operate normally if the operation is forgotten.
In addition, there is a design restriction that the DIP switch must be arranged at an operable position, and if the DIP switch is not arranged at an easily operable position, there is a problem that labor for upgrading work increases. . On the other hand, if the user operates the electronic musical instrument erroneously by arranging the electronic musical instrument in a prominent position, the control program is changed and the electronic musical instrument does not operate normally.
Further, when the dip switch is switched, which model function is performed as the whole electronic musical instrument is changed, so that there is a problem that it is not possible to cope with a case where individual component devices are upgraded.

  The present invention solves such a problem, and in an electronic musical instrument including a main body portion and a component device selected from a plurality of grades and mounted on the main body portion, the electronic musical instrument is replaced by replacing the component device. It is an object of the present invention to ensure that a control program used for control can be changed to an appropriate one when the grade is changed, and that the control program is not changed in other cases. It is another object of the present invention to enable the control program to be similarly changed even when only some of the component devices are replaced.

In order to achieve the above object, the present invention provides an electronic musical instrument having a main body and at least one component device selected from a plurality of grades according to a model of the electronic musical instrument and mounted on the main body. Storage means for storing, for each model of the electronic musical instrument, a control program necessary for controlling the electronic musical instrument of the model, and control means for controlling the electronic musical instrument using the control program And setting means for setting a control program used by the control means for control among the control programs stored in the storage means, wherein the setting means is provided corresponding to at least one of the component devices. When the component device is mounted on the main body, the switch is set to a state corresponding to the grade of the component device.
Also, in place of the setting means, the component device is provided with transmitting means for transmitting information on the grade of the component device to the main body, and the control means stores the storage in accordance with the information transmitted by the transmitting means. Means for selecting a control program to be used for control from the control program stored in the means may be provided.

The present invention also relates to an electronic musical instrument comprising a main body and a plurality of component devices selected from a plurality of grades for each type and mounted on the main body. For each of the component devices, storage means for storing a control program for controlling a component device of each grade for each selectable grade, and control means for controlling the electronic musical instrument using the control program are provided, Each of the various component devices is provided with a transmission unit for transmitting grade information of the component device to the main unit. The control unit is provided for each type of the component device according to the information transmitted by the transmission unit. A means for selecting a control program to be used for control from the control programs stored in the storage means is provided.
Further, instead of the transmitting means and the means for selecting the control program, a control program used by the control means for control among the control programs stored in the storage means is set for each type of the component device. May be provided.

  The present invention is also an electronic musical instrument comprising a main body, and a plurality of component devices selected from a plurality of grades for each type and mounted on the main body. Storage means for storing, for each selectable grade, a control program for controlling a selectable grade of component device; controlling the electronic musical instrument using the control program; Control means for judging the grade of each of the component devices mounted on the unit, and the control means stores the type of the component device in the storage means in accordance with the information on the determined grade. A means for selecting a control program to be used for control from the control program is provided.

  According to the electronic musical instrument as described above, when the grade of the electronic musical instrument is changed by replacing the component device, the control program used for control can be surely changed to an appropriate control program, and otherwise, the control program is not changed. Can be Further, even when some of the component devices are replaced, the control program can be changed to an appropriate one and the control operation can be performed.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
[First Embodiment: FIGS. 1 to 5]
First, an electronic organ according to a first embodiment of the electronic musical instrument of the present invention will be described. FIG. 1 is a block diagram showing the configuration of the electronic organ.
This electronic organ is configured by mounting component devices such as an upper keyboard 31 and a lower keyboard 32 on a main body 10 shown in FIG. Then, by selecting a component device of an appropriate grade from a plurality of grades and mounting it on the common main body 10, from a high-performance, high-cost upper-grade model to a low-cost, low-function, lower-grade model It is possible to construct a plurality of types of electronic organs of different grades.

In such an electronic organ, the main body 10 includes a CPU 11, a ROM 12, a RAM 13, a storage device 14, a display circuit 15, and detection circuits 16, 21 to 26, which are connected by a system bus 20. Further, a display unit 17 connected to the display circuit 15, an operation panel 18 connected to the detection circuit 16, and a limit switch 36 connected to the detection circuit 26, and a casing (not shown) serving as a frame of the entire electronic organ are also provided. It is included in the main body 10.
The CPU 11 is a control unit that controls the overall operation of the electronic organ. By executing a predetermined control program stored in the ROM 12, the CPU 11 reads and writes data in the ROM 12, the RAM 13 and the storage device 14, and displays the data by the display circuit 15. It also controls the display on the unit 17, the detection of operations and settings by the detection circuits 16, 21 to 26, and the output of sound signals to the sound system 37 by the sound source circuit 27 and the optional sound source circuit 28 described later.

The ROM 12 is a nonvolatile storage unit that stores preset data, control programs executed by the CPU 11, and the like. The control program stored here will be described later in detail.
The RAM 13 is storage means for storing temporarily necessary parameters such as designation of sound effects and accompaniment, and for use as a work memory of the CPU 11.
The storage device 14 includes a hard disk drive, a flexible disk drive, a CD-ROM drive, and the like. The storage device 14 reads tone color data, control programs, and the like recorded on a recording medium such as a flexible disk or a CD-ROM, and performs settings set by a user. This is a means for storing data. Of course, it is not necessary to have all of these drives.

The display circuit 15 is a circuit that controls display on the display unit 17 based on control data sent from the CPU 11. The display unit 17 is configured by a liquid crystal panel, a light emitting diode (LED), or the like, and is a unit that displays information such as a message indicating a setting content and an operation state.
The detection circuit 16 is means for detecting an operation signal from an operation panel 18 connected thereto. The operation panel 18 is provided with controls such as various buttons, switches, dials, and the like, and allows a player to perform operations for setting a tone, an accompaniment pattern, various sound effects, and the like of a sound to be produced in response to operation of a keyboard or an expression pedal (EP). Is a unit for performing The display unit 17 and the operation panel 18 may be configured as an integrated unit.

The detection circuits 21 to 25 are means for detecting operation signals from the upper keyboard 31, the lower keyboard 32, the pedal keyboard 33, the first EP 34, and the second EP 35, which are the component devices connected thereto.
The detection circuit 26 is a circuit for detecting the state of the limit switch 36. The limit switch 36 is provided on or connected to the motherboard of the electronic organ, and the CPU 11 controls the electronic organ. This is a switch that functions as setting means for setting a control program to be used.

The upper keyboard 31, the lower keyboard 32, the pedal keyboard 33, the first EP 34, the second EP 35, the sound source circuit 27, the optional sound source circuit 28, and the sound system 37 can be mounted as component devices to be mounted on the main body 10. I have.
The upper keyboard 31, the lower keyboard 32, and the pedal keyboard 33 are three types of keyboards usually provided in the electronic organ. These keys are equipped with various sensors such as a sensor for detecting the presence / absence and speed of a key press, a sensor for detecting a key press pressure after a key is pressed, and a sensor for detecting a horizontal operation of a key. Key detection operation is detected by these sensors, and the content is transmitted to the CPU 11 via the detection circuits 21 to 23 as the operation signal. The sensitivity and presence / absence of each sensor differ depending on the grade. Generally, the higher the grade, the more finely the characteristics can be detected. In addition, it is conceivable to change the material and shape of the component depending on the grade, thereby giving a difference in operation feeling.

  The first EP 34 and the second EP 35 are foot pedals operated by foot, and the first EP 34 is used for adjusting a volume, and the second EP 35 is used for adjusting a pitch (pitch) and speed. These EPs are also provided with various sensors for detecting the operation, the operation by the player is detected by these sensors, and the contents are sent to the CPU 11 via the detection circuits 24 and 25 as operation signals. As in the case of the keyboard, the presence / absence of a sensor differs depending on the grade. However, the second EP 35 is optional, and the low-grade model may not have the second EP 35 in the first place. This is indicated by the dotted line in FIG.

The sound source circuit 27 is a circuit that generates waveform data in accordance with a sound generation instruction from the CPU 11 and outputs the waveform data to a sound system 37 including an amplifier, a speaker, and the like. The tone generator circuit 27 differs in the type of stored tone, the number of sounds that can be simultaneously sounded, the type of corresponding effect, and the like, depending on the grade. The sound system 37 is common to all grades.
The optional sound source circuit 28 is a sound source unit provided in addition to the sound source circuit 27. As the optional sound source circuit 28, a circuit which is more expensive and has higher performance than a normal sound source circuit, such as a physical model sound source circuit, is often provided. This optional tone generator circuit 28 is also an option like the second EP 35, and may not be provided in a low-grade model.
In this electronic organ, the CPU 11 detects operation signals from the keyboards and the EP, and generates a sound signal based on these operation signals and the set values on the operation panel 18 using the tone generator circuit 27 or the optional tone generator. By transmitting the waveform data to the circuit 28 and generating the waveform data and transmitting the waveform data to the sound system 37, a sounding operation based on the operation of the player can be performed.

In such an electronic organ, even a user who has purchased a lower-grade model can upgrade to an upper-grade model by replacing only the component device. Next, this point will be described. For the sake of simplicity, a description will be given of a case where the electronic organ is provided with two types of products, an upper grade model and a lower grade model, as models using the component devices of the grades shown in Table 1.
Here, the second EP 35 and the optional tone generator 28 are not mounted on the electronic organ of the lower grade model, but this indicates that there is no component device corresponding to the lower grade model. Further, the sound system 37 is common regardless of the model, but if there is at least one different component device according to the model, such a common device may be used.

When such a model is provided, a sub-program 51 for controlling the main body, a sub-program 52a for controlling the upper grade component, and a sub-program 52b for controlling the lower grade component are stored in the ROM 12 as the control program 50 as shown in FIG. I remember. These are control programs for controlling the main unit 10 and each component device mounted on the main unit 10 in the upper grade model, and the lower grade model, respectively, for controlling each component device mounted on the main unit 10. However, a program for controlling a common component device regardless of the model, such as the sound system 37, may be included in the main body control subprogram 51. The CPU 11 performs a control operation using the programs 51 and 52a for the upper grade model and using the programs 51 and 52b for the lower grade model.
That is, the ROM 12 stores a control program necessary for controlling the electronic organ of each model to be provided, regardless of which grade of component device is mounted. The CPU 11 performs a control operation by selecting and executing an appropriate one of these control programs at the time of startup. The control program selected here is set according to the state of the limit switch 36. You.

This processing is shown in the flowchart of FIG.
When the power of the electronic organ is turned on, the CPU 11 executes the boot program included in the preset data and starts the processing shown in this flowchart. Then, after performing necessary initialization processing, the state of the limit switch 36 is determined. In the ON state, the programs 51 and 52a required for controlling the upper grade model are read from the ROM 12, and the programs 51 and 52b required for controlling the lower grade model are written in the RAM 13 and executed in the OFF state. Then, the control operation is started.

Such a limit switch 36 is provided on the housing of the main body 10 in correspondence with at least one of the component devices. FIG. 4 shows an example of this arrangement, and shows the state of the limit switch 36 when the upper-grade and lower-grade component devices are mounted, respectively, in plan and front views. In FIG. 4, reference numeral 19 denotes a part of a housing of the main body 10, and reference numeral 30 denotes a part of any of the component devices. Further, in the front views of (b) and (d), in order to make the figures easy to see, the housing is illustrated as having no front side surface.
In this electronic organ, as shown in FIG. 4, a notch 30a is provided at an end of the board of the component device 30, and when the component device 30 is mounted on the housing 19 of the main body 10, the notch 30a is provided. A limit switch 36 is provided at a position where is located. (A) and (b) show examples in which a lower-grade component device is mounted. In this case, even if the component device is mounted in the housing 19, the top 36a of the limit switch 36 is kept open. And the limit switch 36 is OFF.

On the other hand, (c) and (d) show examples in which a higher-grade component device is mounted. In this case, a regulating member 39 that covers the cutout portion 30a of the component device 30 is provided, and When the device 30 is mounted on the housing 19, the top 36 a of the limit switch 36 is pushed down by the regulating member 39. In this state, the limit switch 36 is ON.
Therefore, when the component device 30 is mounted on the main body 10, the limit switch 36 is turned on / off according to the grade of the component device 30.

  FIG. 5 shows another arrangement example of the limit switch 36. In this figure, parts corresponding to those in FIG. 4 are denoted by the same reference numerals. In the case of this example, the limit switch 36 is provided on the side wall of the housing 19 of the main body 10, and the width of the cutout portion 30a differs between the upper grade component device and the lower grade component device. Even in such a configuration, only when the upper-grade component device is mounted, the top portion 36a of the limit switch 36 is pushed down at the end of the board to turn it on, and when the lower-grade component device is mounted, the limit switch is turned on. It is possible to set the top portion 36a of the 36 to the OFF state while keeping it open. In such a configuration, it is not necessary to provide the regulating member 39.

By the way, when upgrading the lower grade model shown in Table 1 to a higher grade model, the person in charge of the manufacturer removes each lower grade component device and replaces it with a higher grade component device. Install new components. At this time, the limit switch 36, which was OFF when the lower-grade component device is mounted, is switched to ON without performing any switching operation by mounting the upper-grade component device.
Therefore, when the power is turned on after the replacement of the component device, the CPU 11 automatically selects the control program required for controlling the upper grade model by the processing shown in FIG. Each component device of the grade can be appropriately controlled and operated as an electronic organ of a higher grade model. Then, when the grade of the electronic musical instrument is changed by replacing the component device, the control program used for control can be surely changed to an appropriate one, and otherwise, the control program can be prevented from being changed.

In this embodiment, since it is assumed that all the component devices are replaced collectively and the upgrade is completely performed, it is sufficient that the limit switch 36 is provided only at a position corresponding to one component device. Is used to set the entire control program to be used. It is preferable that the limit switch 36 is provided at a position corresponding to a component device having a size somewhat larger than that of the limit switch 36 as shown in FIGS.
However, the shape and arrangement relationship between the limit switch 36 and the component device are not limited to those shown in FIGS. Further, any switch other than the limit switch may be used as long as the switch is in a state corresponding to the grade of the component device when the component device is mounted on the main body unit 10 without performing a switching operation.

Also, here, the control program used for each grade is changed. However, if it is possible to respond by changing only the parameters such as the number of switches without changing the control program, the parameters necessary for controlling each grade are changed. May be stored, different parameters are read out according to the state of the limit switch 36, and the control program is executed using the read out parameters.
Further, the control program may not include the main body control subprogram 51, and a portion corresponding to this may be included in the control program for each model.
Furthermore, since there are two types of model grades, the control program used with only one binary limit switch is set. However, if there are three or more grade models, the switch is set to May be provided, and a control program to be used may be set according to a combination of the states of these switches. In this case, this switch needs to be provided at a position corresponding to a component device using different grades in all models.

[Second Embodiment: FIGS. 6 to 8]
Next, an electronic organ which is a second embodiment of the electronic musical instrument of the present invention will be described. FIG. 6 is a block diagram showing the configuration of the electronic organ.
As in the first embodiment, this electronic organ is also constructed by mounting each component device on a main body 10 'shown in FIG.
The configuration of the main body 10 ′ is almost the same as that of the main body 10 in the first embodiment, except that a communication unit 40 is provided instead of the detection circuits 21 to 26. The communication section 40 is means for transmitting and receiving data between the main body section 10 'and each component device, and can be configured using, for example, a communication interface conforming to the RS232C standard.

Each of the component devices 41 to 47 constituting the electronic organ has the same function as the component device of the same name in the first embodiment, but exchange of data with the main unit 10 ′ is performed by the communication unit 40. The difference is that the communication is carried out through the communication. Further, grade information transmitting units 41a to 47a for transmitting grade information indicating their own grades to the main body unit 10 'in response to an inquiry from the CPU 11 are provided in the various component devices 41 to 47, respectively. These functions can be realized by, for example, a one-chip microcomputer or CPU mounted on each component device.
The electronic organ having the above configuration has the same function as the electronic organ itself as in the first embodiment. In the same manner, it is possible to upgrade by replacing only the component device. However, in this embodiment, the component device is selected for each type and mounted on the main body 10 ', and the partial device is not limited to the model of the finished product. Upgrade can be performed. Next, this point will be described. For the sake of simplicity, it is assumed that the selectable grades are only the upper grade and the lower grade as in the first embodiment.

  The sub-programs 61 to 68 as shown in FIG. That is, in addition to the main body control subprogram 61 for controlling the operation of the main body 10 ', a control subroutine for controlling the selectable grade component device for each selectable grade for each of the various component devices. The program is stored. Then, the CPU 11 selects, in addition to the main body control subprogram 61, a control subprogram corresponding to the component device according to the grade of various other component devices mounted on the main body portion 10 ', and uses these. The control operation is performed.

The control program selected here is determined according to the grade information transmitted from the grade information transmitting units 41a to 47a provided in each component device. For example, when information indicating that this is the upper grade is received from the upper keyboard 41, the upper grade upper keyboard control subprogram 62a is selected and used as a program used for controlling the upper keyboard 41. For example, when information indicating that this is a lower grade is received from the lower keyboard 42, a lower grade lower keyboard control subprogram 63a is selected and used as a program used for controlling the lower keyboard 42.
For a component such as the second EP 45 or the optional tone generator circuit 47 that may not be mounted depending on the grade, a corresponding control program is selected only when the component is mounted. Also, for a component device common to the models of each grade, such as the sound system 37, there is no need to select a control program according to the grade, so there is no need to provide a grade information transmission unit.

FIG. 8 is a flowchart showing the above selection process.
When the power of the electronic organ is turned on, the CPU 11 executes the boot program included in the preset data and starts the processing shown in this flowchart. After performing necessary initialization processing in step S11, the communication unit 40 is controlled in step S12 to communicate with each of the component devices 41 to 47, and is transmitted from the grade information transmission units 41a to 47a provided in these units. Get grade information.
In step S13, based on the respective grade information, a subprogram necessary for controlling each component device is read from the ROM 12, written into the RAM 13, and executed to start a control operation.

In the above-described electronic organ, the CPU 11 automatically performs various types of component devices by the processing shown in FIG. 8 regardless of whether the component devices are replaced for only some types or all component devices. And a control program required for the control is selected, read out from the ROM 12, and executed to operate as an electronic organ. In such a case, there is no need to perform any operation other than the replacement of the component device, so that the work procedure at the time of upgrading can be shortened, and the electronic organ does not operate due to a mistake in setting change or the like. Can be prevented.
Similar to the first embodiment, different parameters may be read out according to the grade information to execute the control program, and the grades are not limited to two types.

Further, when it is assumed that all the component devices are to be replaced collectively as in the case of the first embodiment, the control program 50 as shown in FIG. . In this case, a grade information transmitting unit is provided in at least one of the component devices to be replaced at the time of upgrading, and the CPU 11 uses the same for control in the same manner as in the first embodiment in accordance with information transmitted from this unit. It is preferable to select a control program. In this case, the configuration can be simplified and the cost can be reduced.
Conversely, a switch such as a limit switch as in the first embodiment may be used instead of the grade information transmitting unit. That is, a limit switch corresponding to each component device may be provided, and the CPU 11 may select a control program used for controlling each component device according to the state of each switch. In this case, by changing the shape of each component device for each grade, when the component device is mounted on the main body, the switch is brought into a state corresponding to the grade of the component device.

[Third Embodiment: FIGS. 9 and 10]
Next, an electronic organ according to a third embodiment of the electronic musical instrument of the present invention will be described.
The hardware configuration of this electronic organ is almost the same as that of the first embodiment described with reference to FIG. 1, and the control program stored in the ROM 12 is the same as that of the second embodiment described with reference to FIG. This is the same as in the case of the embodiment.
A dip switch group 70 as shown in FIG. 9 is provided instead of the limit switch 36 shown in FIG. The DIP switch group 70 is provided on the motherboard of the electronic organ or connected to the motherboard, and is configured by DIP switches corresponding to each component unit. By switching the corresponding dip switch for each component device, the CPU 11 can set a control program used for control.

The CPU 11 selects a control program to be used for control according to this setting at the time of startup, and FIG. 10 is a flowchart showing this processing. This processing is shown in FIG. 8 except that the CPU 11 selects a program used for control based on the state of each DIP switch of the DIP switch group 70 instead of the data from the grade information transmitting units 41a to 47a. This is the same as the processing.
In the electronic organ as described above, similarly to the second embodiment, the CPU 11 automatically selects and executes a control program necessary for controlling various kinds of component devices, and operates the electronic organ. It is also possible to respond to the upgrade of only some of the parts.
Then, it is necessary to manually switch the dip switch when replacing the component device, but the device can be configured at a lower cost as compared with the case where the grade information transmitting unit is provided as in the second embodiment.

Note that the types and grades of the component devices described in the above-described embodiments are merely examples, and the present invention is not limited thereto. For example, the display unit 17 and the operation panel 18 may be handled as component devices.
Although an electronic organ has been described here as an embodiment of the electronic musical instrument of the present invention, the present invention is not limited to this, and other types of keyboard musical instruments such as keyboards and synthesizers, as well as stringed instruments, wind instruments, and percussion instruments Of course, the present invention can be applied to various forms of electronic musical instruments. In this case, the component devices naturally differ depending on the type of the electronic musical instrument.

As described above, according to the electronic musical instrument of the present invention, it is possible to reliably change the control program used for control when the grade of the electronic musical instrument is changed by exchanging a component device, In that case, it can be kept unchanged. If a control program is stored for each type of component device, and the control means selects a control program required for control, the control program is changed to an appropriate one even if some component devices are replaced. Then, a control operation can be performed.
Therefore, it is possible to provide an electronic musical instrument capable of easily and reliably changing the grade by the component device.
