JP 2000-147465 A

  Since the information display device described in Patent Document 1 uses a liquid crystal display device having a memory property as a display device, the display content currently being displayed is maintained as it is even when the power source of the device body is shut off. This has the advantage that it is economical without consuming power to maintain the display, and has no adverse effects of noise. However, the conventional information display device as described above relates to a so-called electronic bulletin board that is fixedly installed indoors, outdoors, in a vehicle, etc., and displays information sent from the outside periodically via communication means. In other words, the predetermined information is only presented to the user unilaterally. That is, the user himself / herself selectively accesses the information distribution server based on the display content displayed on the liquid crystal display, and acquires and displays further information related to the display content from the accessed information distribution server. There was no idea about making it happen. Furthermore, recently, as a new display, a sheet-shaped electronic paper that is thin and lightweight and that can save power by holding the display that was being displayed immediately before the power was turned off has been used. It is getting to be. In view of this, the electronic paper that is more power-saving than the liquid crystal display as described above is used, and the user appropriately updates the display contents based on the display contents held by the electronic paper. There has been a demand for an information display device that can acquire and display new information from an external information distribution server, but there has been no such information.

  The present invention has been made in view of the above points, and uses electronic paper that is smaller in power consumption than a liquid crystal display as a display for displaying various types of information and is easy to see for the user. Information display that can access an external information distribution server in accordance with a designation operation based on the display content by the user, and obtain and display further new information related to the display content from the accessed information distribution server An object is to provide an apparatus and a program.

An information display device according to the present invention accesses electronic paper, automatic starting means for periodically turning on the power of the information display device, and a predetermined information distribution server via a communication network in response to the power on. , Acquisition means for acquiring at least link destination information data to be displayed on the electronic paper from the accessed information distribution server, storage means for storing the acquired data, serial generates display data for displaying information on the electronic paper based on憶data, and a control unit that displays the appropriate information on the electronic paper according to the display data thus generated, the power supply described above on an automatic stop means for turning off the, according to the power-on of the information display device by the user, based on said stored data, during said power-off Re-display means for re-displaying information for re-displaying the information held in the child paper, and displaying the corresponding information on the electronic paper according to the re-generated display data, display data, said as associating the link destination information included the data stored in the information to be re-displayed on the electronic paper, based on the re-displayed information to the electronic paper, associated with the information Instructing means for receiving an access instruction to further information, and regenerating the further information related to the information held on the electronic paper during power-off in response to the access instruction The electronic paper obtained from the corresponding information distribution server according to the corresponding link destination information included in the stored data corresponding to the displayed data for display Characterized in that it displays.

According to the present invention, each time the information display device is automatically turned on and off periodically, the information display device is connected to a predetermined information distribution server via the communication network and displayed on the electronic paper from the connected predetermined information distribution server. Get the data of the information that should be. This data includes at least link destination information. The acquired data is stored in the storage means, and the corresponding information is displayed on the electronic paper. At this time, display data for displaying information on the electronic paper is generated based on the acquired data. One of the features of electronic paper is that the display can be maintained even when the power is turned off. Therefore, even if the display data is deleted when the power is turned off, the information acquired from the information distribution server is not consumed. Since the information is automatically updated periodically, the user can always obtain the latest information. On the other hand, if there is power on the information display device by the user, based on the stored data, and then re-display the information displayed on the electronic paper during the power-off has been held, the electronic paper It is possible to accept an instruction to access further information related to the information redisplayed in the screen. At this time, based on the stored data, display data for redisplaying information held on the electronic paper during power-off is regenerated. By regenerating the display data, it is possible to associate with the link destination information included in the information and the stored data to be re-displayed on the electronic paper. According to this, according to the direct access instruction on the electronic paper, according to the stored data, further information related to the information held on the electronic paper during power-off according to the stored data, the corresponding information Since the information is acquired from the distribution server and displayed on the electronic paper, the user can arbitrarily and more easily obtain and display additional information related to the information displayed on the electronic paper from the information distribution server. It becomes like this.

  The present invention can be constructed and implemented not only as a device invention but also as a method invention. Further, the present invention can be implemented in the form of a program of a processor such as a computer or a DSP, or can be implemented in the form of a storage medium storing such a program.

  According to the present invention, since information acquired from an external information distribution server accessed at any time according to periodic power on / off is stored and displayed on the electronic paper, it is displayed even when the power is turned off without consuming power. In addition to maintaining the content, the user can arbitrarily acquire and display additional information related to the display content from the information distribution server based on the display content displayed when the power is off while the power is on. There is an effect that it can be easily performed.

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

  FIG. 1 is a block diagram of a hardware configuration showing an embodiment of the overall configuration of an electronic music apparatus to which an information display apparatus according to the present invention is applied. 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. The performance operator / setting operator 4A selects, for example, a performance operator such as a keyboard provided with a plurality of keys for selecting the pitch of a musical tone, various information to be displayed on the electronic paper 6A, or music playback. This is a setting operator for setting various parameters used for. Examples of the setting operator include a mouse that is a pointing device for operating a predetermined pointer displayed on the electronic paper 6A, various switches for selecting, setting, and controlling tone pitches, tone colors, effects, and the like used during performance or numerical data. There are a numeric keypad for input and a keyboard for character data input. 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 that does not have a memory function. The LCD display 5A displays a list of musical pieces, a musical score of musical pieces being played, and the like according to control by the drive circuit 5, The information set by 4A can be displayed, or the control state of the CPU 1 can be displayed. The LCD display 5A is a display widely used in a conventionally known electronic musical instrument or the like. The LCD display 5A is an electronic paper 6A which will be described later in that the response speed when switching the display is fast. Therefore, it is conceivable to display information obtained from an external server computer 12A (information distribution server) or the like on the LCD display 5A. However, when displaying information on the LCD display 5A, the display itself must emit light, and power must be constantly supplied in order to maintain the display contents being displayed. Therefore, the power consumption is very large compared to the electronic paper 6A. Further, since the LCD display 5A itself emits light, it is very easy for the user to be tired of eyes and unsuitable for a long time. Furthermore, a large screen has a high cost. It is disadvantageous compared with 6A. 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. The information acquired from the external information distribution server 12A is displayed on the electronic paper 6A.

  The LCD display 5A and the electronic paper 6A described above are controlled so that display is turned on and off in response to turning on and off of a power source (not shown) in the electronic music apparatus main body. That is, power is supplied to the LCD display 5A and the electronic paper 6A from the power source of the electronic music apparatus main body. When the power of the apparatus main body is turned on, display of information is started, and the power of the apparatus main body is turned off. Then, the information display is terminated. However, because of the characteristics of the electronic paper 6A, the information being displayed is held in the display state as it is even when the power is turned off (details will be described later).

  Here, the electronic paper 6A that can be attached to the electronic music apparatus 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 a conventionally known microcapsule electrophoresis 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, various information acquired from the external information distribution server 12A can be displayed as an image using white and black on the transparent electrode A side which 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 always applying power from the outside (here, the electronic music apparatus main body), the power consumption required for display can be suppressed, and power saving can be realized. Therefore, for example, the electronic paper 6A as described above is an optimal display for use in a portable mobile electronic music device having a built-in power supply in the main body.

  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. Performance information such as automatic performance data that has been recorded or stored in advance or acquired as content from the external information distribution server 12A is input, and a musical tone 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 stores various data such as Web page data and automatic performance data acquired from the external information distribution server 12A, or various control programs executed by the CPU 1 (for example, “power-on processing by a timer (timer described later) Processing) ”,“ processing when power is turned on by user operation ”, etc.) and data related to control. 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, and is connected to an external server computer 12A (information distribution server) via the communication network X. Various data such as Web page data and automatic performance data can be transmitted / received to / from the information distribution server 12A as necessary. Note that 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. The device to which the information display device according to the present invention is applied is not limited to the form of an electronic music device such as an electronic musical instrument or a personal computer as described above, but a portable communication terminal such as a mobile phone, a karaoke device or a game. As long as the electronic paper 6A can be mounted as a display device such as a device, the present invention may be applied to any type of device / apparatus. 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. Alternatively, a device that does not have a music function may be used.

  Next, as processing related to information display on the electronic paper 6A, “processing when the power is turned on by the timer (timer processing)” executed when the electronic music apparatus main body is turned on by the timer 1A, and electronic music by user operation The “processing when the power is turned on by a user operation” executed when the power of the apparatus main body is turned on will be described separately for each figure. First, every time the timer 1A, which is always driven by a built-in battery (not shown) built in the main body of the electronic music apparatus main body is turned off, measures a predetermined time interval (for example, every minute, The “timer process” that is automatically started every hour, every day, every month, etc. will be described with reference to FIG. The power supply to the timer may be maintained even when the power source of the electronic music apparatus main body is turned off. FIG. 3 is a flowchart showing an example of “timer processing”.

  In step S1, the power source of the electronic music apparatus main body is automatically turned on. Thereby, electric power is supplied to each device constituting the electronic music apparatus shown in FIG. 1, and each device starts operation. In step S2, a predetermined Web site (information distribution server) is accessed via the communication network X. Step S3 obtains Web page data (text data described in a markup language such as HTML, which is the basis of display data, and one or more data consisting of image data) from the accessed Web site. This is stored in the external storage means 10. For example, in accordance with a predetermined Uniform Resource Locator (URL), the corresponding Web site is specified and information can be transmitted and received between each other via the communication network X, and then predetermined Web page data To get. In step S4, Web page display data (display bitmap data) representing the display content of the information displayed on the electronic paper 6A is generated based on the stored Web page data. Since the generation of the Web page display data based on the Web page data is a conventionally known process performed by a predetermined browser (software program) or the like, the description thereof is omitted here.

  In step S5, the generated web page display data is displayed on the electronic paper 6A. After completion of the above processes, the electronic music apparatus main body is automatically turned off to enter a sleep state (step S6). When the power is turned off, the generated web page display data is deleted without being stored in the external storage device 10 or the like. However, the electronic paper 6A does not store web page display data due to the above-described characteristics. Also, the display state of the information that was being displayed when the power was turned off is held as it is. In this way, new information (Web page) is periodically acquired from the information distribution server, and the acquired new information is always displayed on the electronic paper 6A regardless of the power on / off operation by the user himself / herself. Thus, the user can always receive the latest information without being aware of the update to the latest information especially when the power is turned on.

  Next, “processing when the power is turned on by a user operation” executed when the electronic music apparatus main body is turned on by a user operation will be described with reference to FIG. FIG. 4 is a flowchart illustrating an example of “processing when the power is turned on by a user operation”.

  In step S11, Web page data stored in the external storage device 10 is read. Step S12 generates Web page display data based on the read Web page data. In step S13, the generated web page display data is displayed on the electronic paper 6A. That is, the data that is the source of the information that is displayed on the electronic paper 6A when the power is turned off, and that is the web page data that is acquired and saved from the website during the “timer processing” described above. Is read (see step S3 in FIG. 3), and the display contents are redrawn so that the information displayed on the electronic paper 6A when the power is turned off by the user is displayed as it is. In step S14, pointer movement display according to the operation of the mouse or the like by the user is executed on the electronic paper 6A. In step S15, it is determined whether or not further information is accessed by clicking a link or the like in accordance with the pointer operation. If further access is made (YES in step S15), the related web site (information distribution server) is accessed based on the stored web page data (step S16). In step S17, Web page data or content data (automatic performance data or the like) corresponding to the clicked link destination is acquired, and the acquired Web page data or content data is stored in the external storage device 10 or the like. As is known in the art, Web page data obtained from a website is described in, for example, HTML (Hyper Text Markup Language), and a part of the sentence is another sentence (another Web page). By associating with a link (so-called link), link destination information that jumps to another corresponding Web page in response to a click on the location is included. Therefore, when a link is clicked by the user, related information is acquired based on the link destination information of the Web page data. Such processing is not executed if the user side (electronic music apparatus in this embodiment) does not store Web page data, not Web page display data.

  In step S18, it is determined whether or not the acquired data is content data. If the acquired data is content data (YES in step S18), the content data is reproduced (step S19). For example, if the acquired content data is automatic performance data, automatic music performance is started based on the automatic performance data. On the other hand, if it is not the content data but the web page data (NO in step S18), the process returns to step S12 to return to the electronic paper 6A based on the web page data. Repeat the process up to. Thereby, new information related to the display content based on the click operation of the link is displayed on the electronic paper 6A. In step S20, it is determined whether or not a power-off operation has been performed by the user. When the power-off operation is not performed (NO in step S20), the process returns to step S14 and the processes from step S14 to step S20 are repeatedly executed. If the power-off operation has been performed (YES in step S20), the process ends.

  Here, switching of the display content of the electronic paper 6 </ b> A according to the power on / off of the apparatus main body performed in accordance with the execution of each of the above processes will be described using a specific example. FIG. 5 is a conceptual diagram illustrating an example of display contents that are switched and displayed on the electronic paper 6A in accordance with a power on / off timing chart of the apparatus main body. In FIG. 5, a display example (here, an example of “Turn-up calendar”) displayed on the electronic paper 6A is shown in the upper row, and a display state of the electronic paper 6A (showing a rectangular state) is shown in the middle row. The lower row shows the power on / off state (the power on state is indicated by hatching).

  For example, at time t0 on October 7, 200X, if the electronic music device is automatically turned on by starting a timer (first power on), information is acquired from an external information distribution server, and the acquired Information is displayed on the electronic paper 6A. In general, in the electronic paper 6A, since the response speed (response time) from the start of driving of a new display to the completion of the display is very slow compared to the LCD display 5A or the like, the display is performed. Switching takes longer than the LCD display 5A (several tens to hundreds of milliseconds (milliseconds)). Therefore, after some time delay after the power is turned on, “Drawing 1” is performed so as to display “Turn-out calendar of October 7, 200X” (screen display example 1) as illustrated in the electronic paper 6A. . Then, the power is turned off after a predetermined time. However, as described above, since the electronic paper 6A maintains the display even after the power is turned off, the state where “screen display example 1” is displayed continues as it is as shown in the display state. .

  At the time t1 when one day has passed since the first power-on, when the power is automatically turned on again by the timer activation (second power-on), the latest information is acquired from the external information distribution server, It is displayed on the electronic paper 6A. Here, “Drawing 2” is performed so as to display “Turn-up calendar on October 8, 200X” (screen display example 2), one day has passed since the last displayed date. Again, after the power is turned off, the “screen display example 2” displayed on the electronic paper 6 </ b> A remains displayed.

If the user turns on the power before one day has passed since the second power-on (time t2), the web page data acquired and stored from the external information distribution server at the second power-on Based on the above, “screen display example 2” is “redrawn” on the electronic paper 6A. Since the display of “screen display example 2” is held even after the power is turned off in the electronic paper 6A, the “screen display example 2” displayed on the electronic paper 6A when the power is turned on by the user is redrawn. Even so, the user is not actually aware that the user has been redrawn. However, by redrawing the display here, the user can specify the link displayed on the electronic paper 6A, and new information related to the display content can be specified from an external information distribution server according to the specification. Can be newly acquired. Here, in the screen display example 2 “Today is Mr. XX's birthday, click here”, the “here” portion underlined corresponds to the link. When the user performs a designation operation such as the user clicking the link with a pointer or the like (access operation by the user at time t3), new information related to the display content is newly added from the external information distribution server in accordance with the designation “Drawing 3” is performed so that the acquired information is displayed on the electronic paper 6A (screen display example 3). When the user turns on the power, the power on state continues until the user turns off the power.
As described above, in the present embodiment, the information distribution server distributes Web page data customized according to the accessing user (for example, data dedicated to a specific user called “xx's birthday”). I am doing so. This is realized by transmitting data specifying the user from the electronic music device to the server when accessing the information distribution server.

  As described above, since the electronic paper 6A is adopted for the display of the information display device that displays various information while periodically updating the display contents, the power consumption can be further reduced as compared with the conventional case, It is possible to provide a display that is easy to see for the user and easy to see. In addition, with the adoption of the electronic paper 6A as a display device, Web page data including link destination information acquired from the information distribution server via the communication network X is stored, and the Web page is stored when the user turns on the power. By redrawing the display content of the electronic paper 6A based on the data, the user can arbitrarily acquire new information related to the display content even in accordance with the display content retained when the power is turned off. Is easy to do.

Note that the display content of the information displayed on the electronic paper 6A is not limited to the display example of the “daily calendar” as described above, and may be any display content of information. In addition, the content, field, and the like of the information acquired and displayed on the electronic paper 6A according to the timer process may be changed as appropriate. In that case, the content of information distributed on the information distribution server 12A side may be changed as appropriate, or the information distribution server 12A that receives information distribution on the electronic music device side may be changed as appropriate. .
As a function similar to the present invention, there is a so-called resume function that retains the contents being displayed when the power is turned off in the personal computer, but the conventionally known resume function does not hold the display while the power is turned off. This is different from the present invention in that the information being displayed is not updated regularly. Also, a so-called standby function has been conventionally known, but not only for the same reason as the resume function, but also for stopping the power supply to the display. Since it does not stop, it is different from the present invention.

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, the electronic music apparatus main body may be physically separated from the electronic music apparatus main body so that a display switching instruction can be performed wirelessly from the electronic music apparatus side. In the case of fixed installation, it is preferable to install the electronic paper 6A on the musical score stand. It is preferable to do this. 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 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 may be displayed with this display and electronic paper 6A. Different types of information may be displayed. When displaying the same type of information, for example, information for one page may be displayed on the electronic paper 6A, and only a part of the information may be enlarged and displayed on another display.
