  Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 1 is a hardware configuration block diagram showing an embodiment of the overall configuration of an electronic music apparatus according to the present invention. The electronic music apparatus (for example, an electronic musical instrument or a personal computer) shown in this embodiment is controlled by a microcomputer including a microprocessor unit (CPU) 1, a read only memory (ROM) 2, and a random access memory (RAM) 3. . The CPU 1 controls the operation of the entire electronic music apparatus. This CPU 1 is connected to the ROM 1, RAM 3, detection circuit 4, drive circuit 5, electronic paper drive circuit 6, sound source circuit 7, effect circuit 8, external storage device 10, external storage device 10, MIDI interface (I / O) via the data and address bus 1D. F) 11 and a communication interface (I / F) 12 are connected to each other. Further, the CPU 1 is connected to a timer 1A for measuring the interrupt time and various times in the timer interrupt process (interrupt process). For example, the timer 1A generates a clock pulse, and gives the generated clock pulse to the CPU 1 as a processing timing command or to the CPU 1 as an interrupt command. The CPU 1 executes various processes according to these instructions.

  The ROM 2 stores various programs executed by the CPU 1 and various data. The RAM 3 is used as a working memory that temporarily stores various data generated when the CPU 1 executes a predetermined program, or as a memory that stores a currently executed program and related data. A predetermined address area of the RAM 3 is assigned to each function and used as a register, flag, table, memory, or the like. In this embodiment, for example, there are a manual switch (MNL_SW) flag, a manual page (MNL_PG) flag, a manual display mode (MNL_MD) flag, etc. (described later). The performance operator / setting operator 4A is displayed on the electronic paper 6A, which is a performance operator for hand-playing performance by a user such as a keyboard having a plurality of keys for selecting the pitch of a musical tone, for example. A setting operator for selecting various types of information or setting various parameters used for music playback. For example, in order to display an electronic manual (instruction manual) as various information on the electronic paper 6A, a manual switch for setting the device setting of the apparatus to "manual display mode", an automatic performance switch for instructing start / stop of automatic performance, a performance There are timbre switches that specify the timbre used at times. The detection circuit 4 detects the pressing and release of each key of the performance operator to generate a detection output, detects the operation state of the setting operator, and sends switch information corresponding to the operation state via the data and address bus 1D. Output to the CPU 1. Of course, the performance operator is not limited to a keyboard instrument, and may be any type of instrument such as a stringed instrument, a wind instrument, or a percussion instrument.

  The LCD display 5A is a display composed of, for example, a liquid crystal display panel, etc., and displays a list of music, a score, and the like according to control by the drive circuit 5, and displays information set by the setting operator 4A. Alternatively, the control state of the CPU 1 can be displayed. The LCD display 5A is a display widely used in conventionally known electronic musical instruments, but the LCD display 5A has a high response speed when switching display of various information and switching pages. Since it is more advantageous than the electronic paper 6A, it is conceivable to display a manual on the LCD display 5A. However, when displaying various information such as a manual on the LCD display 5A, the display itself must emit light, and power is always supplied in order to keep the display contents being displayed. The power consumption is very large compared to the electronic paper 6A because it must be kept. Further, since the LCD display 5A itself emits light, it is very easy for the user to get tired of eyes, and is not suitable for keeping a long time as compared with a paper manual printed on normal paper. The larger one is disadvantageous compared to the electronic paper 6A in that the cost is high. Therefore, in this electronic music apparatus, in addition to the LCD display 5A, an electronic paper 6A (flexible sheet-like display) can be detachably mounted as a display, and is mounted according to the control of the electronic paper drive circuit 6. A manual (electronic manual based on electronic manual data) can be displayed on the electronic paper 6A.

  Here, an electronic paper 6A that can be attached to an electronic music apparatus and can be used to display an electronic manual will be described with reference to FIG. Various types of electronic paper 6A are known, but here, as an example, description will be given by taking microcapsule-type electronic paper as an example. FIG. 2 is a schematic diagram showing the structure of microcapsule-type electronic paper.

  As shown in FIG. 2, a microcapsule-type electrophoretic electronic paper 6A has a transparent so-called electronic ink between a transparent electrode A made of films and the like and a back electrode B made of a TFT substrate. Many microcapsules C are arranged (however, only two are shown here for convenience of illustration). In this transparent microcapsule C, black fine particles D and white fine particles E are enclosed, and by applying a voltage (charge), the black fine particles D and the white fine particles E are electrophoresed to display black and white. Thus, an arbitrary image can be displayed on the transparent electrode A. Specifically, carbon black particles that are negatively charged as black fine particles D are displayed on each of transparent electrode A and back electrode B with respect to microcapsules C in which positively charged titanium oxide particles are encapsulated as white fine particles E. By applying positive and negative charges according to the image, the white fine particles E are collected on the negative charge side, and the black fine particles D are collected on the positive charge side. In this way, musical scores, lyrics, manuals, and the like can be displayed as images using white and black on the transparent electrode A side that is the screen surface.

  The electronic paper 6A having such a structure has the following advantages. Since the contrast is high and the reflection type allows the user to view an image displayed by light emitted from an external light source without emitting light over the entire screen, it is easy to see and easy on the eyes. Because it is thin and lightweight and can be bent appropriately, it is easy to carry. Further, since the structure is simple, it is possible to reduce the cost for increasing the screen size. Furthermore, since the display state is maintained as it is without constantly applying power from the outside, power consumption is reduced and power is saved. However, although the electronic paper 6A has such advantages, the response speed (response time) from the start of driving a new display to the completion of the display is much higher than that of the LCD display 5A or the like. Since it is slow, it has a drawback that it takes more time than the LCD display 5A to switch the display by page switching or the like (several tens to hundreds of tens of milliseconds (milliseconds)). However, for manuals, it is extremely rare and rare to switch pages and display them frequently, so the above-mentioned drawbacks are not so problematic. Further, when the manual is displayed on the electronic paper 6A, in addition to the above-mentioned advantages, it is similar to a paper manual printed on paper at first glance. There is also an advantage that it can be used without damaging it. Therefore, in the electronic music apparatus shown in FIG. 1, an electronic paper 6A is provided as a display different from the LCD display 5A, and setting information and the like are displayed on the LCD display 5A. In order to display a manual, the two display devices are used separately depending on the contents to be displayed. Of course, the content displayed on the electronic paper 6A is not limited to the manual.

  In the above embodiment, the electronic paper 6A is shown as an example of a microcapsule electrophoresis type, but the invention is not limited to this, and the electronic paper 6A according to another known type may be used. For example, any of various types of electronic paper 6A such as a twisting ball method, a horizontal movement type electrophoresis method, and an electrolytic deposition / dissolution method may be adopted. However, in such a case, since the driving method of the electronic paper 6A differs depending on each method, the electronic paper 6A may be driven by a driving method corresponding to each adopted method.

  Returning to the description of FIG. 1, the tone generator circuit 7 can simultaneously generate musical tone signals in a plurality of channels, and is generated in accordance with the operation of the performance operator 4A by the user given via the data and address bus 1D. Various performance information (automatic performance data or the like) that has been recorded or stored in advance or obtained from the outside is input, and a musical sound signal is generated based on the performance information. The tone generator circuit 7 controls the generated tone signal based on various parameters, and generates the generated tone signal from the sound system 9 including an amplifier and a speaker via the effect circuit 8. The effect circuit 8 gives an effect to the musical sound signal from the sound source circuit 7. Any conventional configuration may be used for the sound source circuit 7, the effect circuit 8, and the sound system 9. For example, the tone generator circuit 7 may employ any of various tone synthesis methods such as FM, PCM, physical model, formant synthesis, etc., or may be configured with dedicated hardware, or a CPU 1 or DSP (not shown). ) Or the like.

  The external storage device 10 is used for electronic manual data displayed on the electronic paper 6A and electronic manual data (see FIG. 3 to be described later) that is the basis of the bundled paper manual, for each operator or for operation of a predetermined operator. A manual page table (see FIG. 4 to be described later) corresponding to the corresponding page of the manual to be displayed for each function operated in response (including a function operated by software), for automatic performance Various data such as performance information, various control programs executed by the CPU 1 (for example, “manual display process” described later), data related to control, and the like are stored. When no control program is stored in the ROM 2, the control program is stored in the ROM 2 by storing the control program in the external storage device 10 (for example, a hard disk) and reading it into the RAM 3. The CPU 1 can be operated in the same manner as in the case. In this way, control programs can be easily added and upgraded. The external storage device 10 is not limited to a hard disk (HD), but a flexible disk (FD), a compact disk (CD-ROM / CD-RAM), a magneto-optical disk (MO), a DVD (Digital Versatile Disk), etc. Any storage device may be used as long as the storage device uses various external storage media. Alternatively, a semiconductor memory such as a flash memory may be used.

  The MIDI interface (I / F) 11 inputs MIDI format performance information (MIDI data) from another externally connected MIDI device 11A or the like to the electronic music device, or performs MIDI format performance from the electronic music device. This is an interface for outputting information (MIDI data) to another MIDI device 11A or the like. The communication interface (I / F) 12 is connected to a wired or wireless communication network X such as a LAN, for example, and is connected to an external server computer 12A via the communication network X. Various data such as manual data can be received. Such a communication interface 12 may include both of a wired interface and a wireless interface.

  Note that the electronic music apparatus is not limited to one in which the performance / setting operation element 4A, the LCD display 5A, the electronic paper 6A, the sound source circuit 7 and the like are built in one apparatus body, but each is configured separately, and MIDI It may be configured to connect each device using communication means such as an interface or various networks. In addition, the electronic music apparatus according to the present invention is not limited to the form of an electronic musical instrument or personal computer, but can be applied to any form of apparatus / equipment such as a portable communication terminal such as a mobile phone, a karaoke apparatus, or a game apparatus. May be. When applied to a portable communication terminal, not only when a predetermined function is completed with only the terminal, but also a part of the function is provided on the server side, and the predetermined function is realized as a whole system composed of the terminal and the server. You may make it do.

  In the electronic music apparatus according to the present invention, not only a paper manual printed on paper is included, but also electronic manual data is attached, and the user places the electronic manual on the electronic paper 6A based on the electronic manual data. It can be displayed. Therefore, the electronic manual data, the electronic manual displayed on the electronic paper 6A, and the paper manual bundled with the apparatus will be briefly described with reference to FIG. FIG. 3 is a conceptual diagram showing the relationship among electronic manual data, electronic paper, and paper manual. As can be understood from FIG. 3, the paper manual PM is one in which electronic manual data MD is sent to the printing press PR, and the contents thereof are printed on the paper or the like by the printing press PR. Such a paper manual PM is printed by the manufacturer of the electronic music apparatus, and the printed paper manual PM is shipped with the electronic music apparatus so as to reach each user. . In addition, the electronic manual data MD that is the basis of the paper manual PM is bundled by the manufacturer by being built in the electronic music device or stored in an external storage medium, so that the electronic music device can be shipped. In addition, the electronic manual data MD is delivered to each user. Using the electronic manual data MD, the user can display an electronic manual having the same contents as the enclosed paper manual PM on the electronic paper 6A.

  The electronic manual data MD that is the basis of the electronic manual displayed on the electronic paper 6A is not limited to being stored in advance in the storage device (ROM, external storage medium, etc.) of the electronic music device as described above. It may be downloaded appropriately from an external website connected via the communication interface 12 and stored in an external storage medium or the like. Alternatively, the electronic manual data MD may be received and displayed every time switching to manual display or page switching without downloading. Also, the electronic manual data used for printing the paper manual PM and the electronic manual data used for display on the electronic paper 6A may have different data formats, and any format may be used as long as the description content is common.

  Next, the data structure of the manual page table (corresponding information) will be described with reference to FIG. FIG. 4 is a conceptual diagram showing the data structure of the manual page table. The manual page table includes a description related to the operated operator or a function operated by the operated operator when the operator is operated with the manual switch turned on (manual display mode). This data is prepared in advance for quickly switching to and displaying the manual of the corresponding page (see FIG. 5 described later in detail). As shown in FIG. 4, the manual page table is provided for each function of the device such as a timbre edit function that is operated for each switch such as a timbre switch or an automatic performance switch or according to an operation of a predetermined operator. In addition, a manual page in which related descriptions such as operation explanations and function explanations of the corresponding switches are stored is stored. In the example shown here, the description related to the tone switch is on pages 10 and 15, the description related to the automatic performance switch is on pages 52, 58, and 80, and the description related to the tone edit function is 22, 40, 105. The case where each page is made is shown as an example. The correspondence relationship is not limited to a page, and a row or the like may be associated.

  Next, “manual display processing” for displaying the manual of the corresponding page on the electronic paper 6A according to the switch operation by the user will be described with reference to FIG. FIG. 5 is a flowchart showing an embodiment of a series of “manual display processing” executed by the CPU 1 shown in FIG. However, here, for convenience of illustration, the “manual display process”, which is one continuous process, is divided into two, the process corresponding to the first half part in FIG. 5A is continued from the first half process shown in FIG. 5A in FIG. 5B. Each of the processes corresponding to the latter half of the execution is shown.

  As shown in FIG. 5A, in step S1, it is determined whether or not there is an on event of the manual switch (SW). The manual switch is, for example, a type of switch that is in an on state as long as the user keeps pressing and is in an off state when the user stops pressing. If it is determined that the manual switch has been turned on, that is, it has been pressed by the user (YES in step S1), the manual switch (MNL_SW) flag is set to “1” (step S2). Further, the manual page (MNL_PG) flag is reset to “0” (step S3). In step S4, it is determined whether or not a manual switch off event has occurred. If it is determined that the manual switch has been turned off, that is, the manual switch has been released by the user (YES in step S4), the manual switch (MNL_SW) flag is reset to “0” (step S5). In step S6, it is determined whether or not the manual page (MNL_PG) flag is set to “0”. If the manual page (MNL_PG) flag is set to “0” (YES in step S6), it is further determined whether or not the manual display mode (MNL_MD) flag is set to “0” (step S7). ). When the manual display mode (MNL_MD) flag is set to “0” (YES in step S7), the manual display mode (MNL_MD) flag is set to “1” and the top page of the manual is set on the electronic paper 6A. Alternatively, the previous display page is displayed (step S8). On the other hand, when the manual display mode (MNL_MD) flag is not set to “0” (NO in step S7), the manual display mode (MNL_MD) flag is set to “0” and the electronic paper 6A is manually displayed. Is finished (step S9). At the end of this manual display, other information is displayed on the electronic paper 6A.

  Subsequent to the process in step S8 or step S9 in FIG. 5A described above, the process in step S10 shown in FIG. 5B is executed. In step S10, it is determined whether or not any of the “+ (plus)” switch, the “− (minus)” switch, and the numeric keypad is operated by the user. If it is determined that one of the “+” switch, the “−” switch, and the numeric keypad is operated (YES in step S10), whether or not the manual switch (MNL_SW) flag is set to “1”. Is determined (step S11). If the manual switch (MNL_SW) flag is set to “1” (YES in step S11), both the manual page (MNL_PG) flag and the manual display mode (MNL_MD) flag are set to “1” (step S12). ). Furthermore, the display page of the manual is changed in accordance with the operation of the “+” switch, “−” switch, or numeric keypad by the user (step S13). That is, for example, when the “+” switch is operated once in the ON state of the manual switch, the manual of the “current display page + 1” page can be changed to be displayed. Further, when the “−” switch is operated three times while the manual switch is on, the manual of the “current display page-3” page can be changed to be displayed. In other words, when the “+” or “−” switch is operated, pages corresponding to the number of times each switch is operated are added to or subtracted from the currently displayed page, and the pages are switched and the manual operation is performed. Is displayed. Further, when “168” is designated with the numeric keypad while the manual switch is on, the page is directly switched to the “168” page to display the manual.

  On the other hand, if the manual switch flag (MNL_SW flag) is not set to “1” in step S11 (NO in step S11), the normal operation according to the operation of the “+” switch, the “−” switch, and the numeric keypad. The function is executed (step S14). In this case, without changing the manual display page as described above (see step S13), regardless of whether or not the manual is displayed on the electronic paper 6A, the “+” switch and “−” switch Normally, the setting value to be changed is reset by “+ (plus)” or “− (minus)” according to the operation, or the setting value to be changed is reset directly according to the numeric keypad operation. Perform the function.

  In step S15, it is determined whether or not the above-described operators, that is, the “+” switch, the “−” switch, and other operators other than the numeric keypad are operated by the user. When it is determined that the “+” switch, the “−” switch, and other operation elements other than the numeric keypad are operated (YES in step S15), whether or not the manual switch flag (MNL_SW flag) is set to “1”. Is determined (step S16). When the manual switch flag (MNL_SW flag) is set to “1” (YES in step S16), both the manual page flag (MNL_PG flag) and the manual display mode flag (MNL_MD flag) are set to “1”. (Step S17). Then, in a state where the manual switch flag (MNL_SW flag) is set to “1”, it is determined whether or not the same operator other than the “+” switch, the “−” switch, and the numeric keypad has been operated continuously (step). S18). When it is determined that the same operator has been continuously operated (YES in step S18), the manual page table (see FIG. 4) is referred to, and the next description page related to the continuously operated same operator And the manual of the page is displayed on the electronic paper 6A (step S19). For example, when the automatic performance switch is continuously operated while the manual switch is on, the first page “52” is displayed on the next page based on the manual page table (see FIG. 4). Switching to a certain “58” page, the manual is displayed on the electronic paper 6A. On the other hand, when it is determined that the same operator is not continuously operated, that is, another operator other than the “+” switch, the “−” switch, and the numeric keypad is operated (NO in step S18), the manual page. With reference to the table (see FIG. 4), the first description page related to the operated operator is obtained, and the manual of the page is displayed on the electronic paper 6A (step S20). For example, when the timbre switch is newly operated while the manual switch is on, based on the manual page table (see FIG. 4), the first page “10” is switched to the electronic paper 6A. Is displayed.

  On the other hand, if it is determined in step S16 that the manual switch flag (MNL_SW flag) is not set to “1” (NO in step S16), the normal functions of the other operated operators are executed. (Step S21). In this case, regardless of whether or not the manual is displayed on the electronic paper 6A, for example, the timbre setting is executed when the timbre switch is operated, and when the timbre edit function is instructed, the timbre edit screen is displayed. Is displayed on the LCD display 5A, and when an automatic performance switch is operated, a normal function corresponding to other operated operators is executed, such as starting / stopping automatic performance. When any one of steps S19, S20, and S21 is completed, the process returns to step S1 shown in FIG. 5A, and the series of steps from step S1 to step S21 is repeated.

  A specific operation associated with the “manual display process” will be briefly described separately. First, when the manual switch is turned on / off independently when the manual is not displayed on the electronic paper 6A (non-manual display mode), the device is set from the non-manual display mode to the manual display mode, and the electronic paper 6A is set. The top page of the manual or the previous display page is displayed above (step S8). On the other hand, when the manual switch is turned on in the state where the manual is not displayed on the electronic paper 6A (non-manual display mode) and the “+”, “−”, or numeric keypad is operated, the non- The device is set from the manual display mode to the manual display mode. If the “+” or “−” switch is operated, the top page of the manual is displayed on the electronic paper 6A, and if the numeric key is operated, the manual corresponding to the indicated numerical value is displayed. A page is displayed (step S13). Of course, in the state where the manual is not displayed on the electronic paper 6A (non-manual display mode), the “+”, “−”, numeric keypad, and other operators are operated independently without operating the manual switch. In this case, the normal function of each operator is executed (step S14 or step S21).

  When the manual switch is not turned on during manual display (manual display mode), if the “+”, “−”, numeric keypad, or other controls are operated independently, The function is executed (step S14 or step S21). If the “+”, “−”, or numeric keypad is operated while the manual switch is turned on during manual display (manual display mode), the page of the manual being displayed according to the operated control Switching is performed (step S13). When other controls other than “+”, “−”, and numeric keys are operated while the manual switch is turned on during manual display (manual display mode), refer to the manual page table and perform the operation. Switching is performed so as to jump to the manual page in which the description related to the operated controller is made. However, at this time, when the same operator is operated continuously, pages related to the operator are sequentially switched and displayed (step S19 or step S20). If the manual switch is turned on / off independently during manual display (manual display mode), the device is set from the manual display mode to the non-manual display mode, the manual display on the electronic paper 6A is terminated, and other information is displayed. Displayed (step S9).

  As described above, since the electronic paper 6A can be employed as a display for manual display, it is possible to reduce power consumption and to provide a display that is easy on the eyes and easy to see. In other words, the electronic paper 6A is a reflective display and can easily increase the size of the screen at a low cost. Therefore, it is possible to easily provide a user-friendly display that is easy on the eyes.

In addition, when operating various controls while holding down the manual switch, it relates to explanations on how to use the controls, setting contents, etc., or explanations of functions of the device that are operated by operating the specified controls. However, the operation mode is not limited to this. For example, during manual display (manual display mode), the corresponding page of the manual related to the operated operator / function may be displayed at all times, or it is related to when the operator is operated for a predetermined operation (for example, double click). A manual page may be displayed.
In addition, when a predetermined function is not fixedly assigned to a certain operation element (for example, when setting a function that is a display unit + surrounding operation element or editing a parameter), the operation element To display the manual page related to the function currently set / edited (ie, related to the function currently displayed on the display).
In addition, when a touch sensor is provided on the surface of the electronic paper 6A and the display is touched with respect to the predetermined operation element / function on the manual, the related operation element / function is notified to the user. Also good. For example, when touching on a manual page related to timbre setting, the display on the LCD display 5A is switched to the timbre setting screen, or when touching on a manual page related to automatic performance, it is provided on a switch (or near the switch) related to automatic performance. The illuminated LED may be lit (flashing).

The electronic paper 6A is not limited to being detachably installed on the main body of the electronic music apparatus via a dedicated or general-purpose interface such as USB, but may be fixedly installed on the electronic music apparatus. Alternatively, it may be physically separated from the main body of the electronic music apparatus, and a page switching instruction may be performed wirelessly from the electronic music apparatus side. When it is fixedly installed, it is preferable to install the electronic paper 6A on the musical score stand or the like, and when it is detachable, it is preferable that it can be placed on the musical score stand. The size and shape of the electronic paper 6A are preferably the same as or close to the size and shape of the paper manual. When the electronic paper drive circuit 6 is detachable, the electronic paper drive circuit 6 may be fixed to the electronic music apparatus main body, and only the electronic paper 6A may be detachable, or the entire electronic paper drive circuit 6 may be detachable. Furthermore, when it is possible to attach and detach, a plurality of types of electronic paper 6A may be connected.
In addition, when the other display (LCD display 5A etc.) which is not electronic paper 6A is also provided simultaneously like the Example mentioned above, the same kind of information (manual etc.) is shown with this display and electronic paper 6A. It may be displayed, or different types of information may be displayed. When displaying the same type of information, for example, one page of information may be displayed on the electronic paper 6A, and only a part of the information may be displayed on the other display device.
