The image of the first page of Chapter 3 is displayed, the image of the first page of Chapter 4 is displayed on the fifth electronic paper 5, and the image of the first page of Chapter 5 is displayed on the sixth electronic paper 5. Then, the image of the first page of Chapter 6 is displayed on the seventh electronic paper 5. Since there are no chapters to be assigned to the eighth and ninth electronic papers 5, a blank sheet is displayed. Then, in the last tenth electronic paper 5, there is a message to end the chapter selection such as “End chapter selection and select content to be browsed” and switch to display for content selection. Is displayed.

  Here, the state in which the image of the first page of the first chapter is displayed on the second electronic paper 5 is the sample page 504 shown in FIG. As shown in FIG. 11, the actual information on the first page is described in the sample page 504 to help the user select which chapter to browse.

  Then, when one electronic paper 5 is turned from the state of the schematic diagram 630 in FIG. 15 and the sample page 504 that is the image of the first page of the first chapter is opened, it is determined that the first chapter is selected. 16, the page order table is re-created, and the order of the electronic paper 5 that is the identification information “S21121” on which the sample page 504 is displayed is changed from the second to the first. Similarly, the electronic paper 5 having the third identification number “S47613” is changed to the second, and the order of all the ten electronic papers 5 is changed.

  Then, as illustrated in a schematic diagram 650 illustrated in FIG. 17, the second to tenth electronic papers 5 display images of pages subsequent to the first chapter. Specifically, the image of the second page is displayed on the second electronic paper 5, the image of the third page is displayed on the third electronic paper 5, and the fourth page is displayed on the fourth electronic paper 5. The image of page 5 is displayed on the fifth electronic paper 5, the image of page 6 is displayed on the sixth electronic paper 5, and page 7 is displayed on the seventh electronic paper 5. The image of the eye is displayed, the image of the eighth page is displayed on the eighth electronic paper 5, the image of the ninth page is displayed on the ninth electronic paper 5, and the image of the tenth electronic paper 5 is 10. The image of the page is displayed. In the state of this schematic diagram 650, the user can start browsing the information. Note that this Chapter 1 is composed of 12 pages of images.

  Then, as illustrated in a schematic diagram 660 illustrated in FIG. 18, when the first electronic paper 5 is turned and the electronic paper 5 (identification information “S47613”) on which the image of the second page is displayed is opened, the page order is increased. The table is re-created, and the order of the electronic paper 5 having the identification information “S47613” is changed from the second to the first. Similarly, the third electronic paper 5 having the identification number “S40112” is changed to the second, and the order of all the ten electronic papers 5 is changed. Then, an image of the subsequent page (the 11th page) is displayed on the electronic paper 5 of the identification information “S21121” which is the turned electronic paper 5. As described above, when the first electronic paper 5 is turned, the next page is displayed on the turned electronic paper 5.

  When the electronic paper 5 is further turned and the electronic paper 5 on which the image of the fifth page is displayed is opened, a schematic diagram 670 shown in FIG. 19 is obtained. Since the first chapter has only images for 12 pages, there is no image to be displayed after the image of the 12th page is displayed on the 8th electronic paper 5, so the 9th and 10th electronic papers are displayed. In 5, blank paper is stored.

  When the electronic paper 5 is further turned and the electronic paper 5 (identification information “S47613”) displaying the image of the twelfth page, which is the last page, is turned, the blank electronic paper 5 is opened. . Then, the order of the electronic paper 5 (identification information “S40112”) on which the opened white paper is displayed is changed from the ninth to the first. Similarly, the electronic paper 5 having the identification number “S00134” which is the tenth is changed to the second, and the order of all the ten electronic papers 5 is changed. Also, since the blank electronic paper 5 is opened, it is determined that browsing of this chapter has been completed, and the state shown in FIG. The user can select the next chapter and continue browsing or end the chapter selection and shift to content selection.

  As described above, the user can select the content to be browsed by turning the electronic paper 5. In addition to selecting the content to browse, you can select up to chapters, so you can easily reach the target page if you want to browse from the content that you have browsed halfway or only want to browse a specific chapter. can do.

  Next, the display control of the electronic paper 5 described above will be described in detail with reference to the flowcharts of FIGS. 21 is a flowchart of the main process performed by the CPU 31 of the master paper 3, FIG. 22 is a flowchart of the content selection process performed by the main process, and FIG. 23 is a chapter selection process performed by the main process. 24 is a flowchart of the first display process performed in the chapter selection process, FIG. 25 is a flowchart of the second display process performed in the chapter selection process, and FIG. It is a flowchart of the display content update process implemented by a process. FIG. 27 is a flowchart of the turning number calculation process performed in the main process, the content selection process, the chapter selection process, and the display content conversion process.

  The main process shown in FIG. 21 is started when the power of the display device 1 is turned on, and is continuously repeated. First, the output value of the acceleration sensor 50 is acquired every 0.5 seconds, and it is determined whether or not the output value of the acceleration sensor 50 has changed (S1). This determination is a determination for determining whether or not the display device 1 has been moved. In the main process, when the display device 1 is moved by being held by the user or the like, the process after S2 is performed, and when the display apparatus 1 is not moved, the process of S1 is repeatedly performed and moved. stand by.

  Here, the acceleration sensor value storage area 336 of the RAM 33 is used. This acceleration sensor value storage area 336 is provided with a storage area for storing the previous measurement value and the current measurement value. Note that the initial value of the previous measurement value and the current measurement value is “0”. Specifically, in S1, the value of the current measurement value is stored in the previous measurement value, and the output value of the acceleration sensor 50 is acquired and stored in the current measurement value. Then, the previous measurement value and the current measurement value are compared, and if they are different, the output value changes and it is determined that the display device 1 has been moved (S1: YES).

  If both values are the same, the output value has not changed, and it is determined that the display device 1 has not been moved (S1: NO). Note that the threshold at which the measured value of the acceleration sensor 50 in the S1 process is determined to be different from the previous value is a case where the difference in acceleration converted from the measured value is, for example, 5G or more. The reason is that the user puts the display device 1 in a bag and the acceleration slightly changes, and the user lifts the display device 1 by hand for the purpose of starting browsing, and the acceleration value changes greatly. This is to distinguish the case.

  If they are different, the output value changes. If the display device 1 is moved (S1: YES), a page order table is created and stored in the page order table storage area 331 (S2). Specifically, an inquiry process is performed on ring positions 0 to 255 using the position detection ring 24. Since the serial number is returned from the position where the slave paper 4 exists, the position in the ring and the serial number are associated with each other and stored in the page order table. When all the in-ring positions have been inquired, the page order table is sorted by the in-ring position values, and the paper page numbers are assigned in order from “1” in ascending order of the in-ring position values.

  Then, a message that prompts the user to determine whether to display the previously viewed content again, such as “Do you want to display the previously displayed content?” Is displayed on the display unit 36 of the first electronic paper 5 (S3). . Here, in addition to the message, an instruction for an operation for selecting to display the content browsed last time is displayed. In the present embodiment, it is assumed that turning one sheet of electronic paper 5 is an instruction to select previously browsed content, and turning the other number is an instruction to display other content. . Therefore, for example, a message such as “turn one sheet to display the previously displayed content. Turn two or more papers to display other content” is displayed.

  And in order to measure the time for determining whether the display apparatus 1 is browsed by the user now, the present time is acquired from the time measuring apparatus 51, and it memorize | stores in the measurement start time storage area 337 (S4). ). Then, it is determined whether or not the output value of the acceleration sensor 50 has changed (S5). While the display device 1 is being browsed by the user, it is held in the hand and the display device 1 is shaken, so that the output value of the acceleration sensor 50 changes. Conversely, when the user stops browsing the display device 1 and places it on a desk or the like, the output value of the acceleration sensor 50 does not change because the display device 1 is stationary. Therefore, it is determined whether or not the output value of the acceleration sensor 50 has changed. Note that the threshold at which the measured value of the acceleration sensor 50 is determined to have changed compared to the previous time is a case where the difference in acceleration converted from the measured value is 1 G or more. In order to detect subtle shaking of the hand, it is set smaller than the threshold value in S1.

  If the output value of the acceleration sensor 50 has changed (S5: YES), a turning number calculation process for calculating the number of pages of the electronic paper 5 is performed (S7, see FIG. 27). On the other hand, if the output value of the acceleration sensor 50 has not changed (S5: NO), the process proceeds to S5, where it is determined whether 10 minutes have passed since the time of S4 (S6), and 10 minutes have passed. If not (S6: NO), the process returns to S5, and the change of the output value of the acceleration sensor 50 is determined again (S5). Then, the processes of S5 and S6 are repeated, and when 10 minutes have elapsed, it is determined that the user has placed the display device 1, that is, there is no intention of browsing (S6: YES), and the process proceeds to S18.

  Here, the turning number calculation process (S7) will be described with reference to the flowchart of FIG. In the turning number calculation process, first, the current time is acquired from the timing device 51 and stored in the measurement start time storage area 337 (S121). Then, the current page order table stored in the page order table storage area 331 is stored in the first old page order table storage area 332 as the first old page order table (S122). Then, it waits for 1 second (S123).

  Then, again, as in the page order table creation process of S2 of the main process, the intra-ring position inquiry process newly performed using the position detection ring 24 is performed, and the page order table is created. It is stored in the page order table storage area 331 (S124). Next, the page order table created in S124 is compared with the first old page order table stored in the first old page order table storage area 332 (S125). If the order of the electronic paper 5 is different by comparing the two page order tables, that is, if the electronic paper 5 is turned (S125: YES), it is stored in the page order table storage area 331. The current page order table is stored in the second old page order table storage area 333 as the second old page order table (S129). Then, it waits for 1 second (S130).

  Then, the intra-ring position inquiry process newly performed using the position detection ring 24 is performed, and a page order table is created and stored in the page order table storage area 331 (S131). Then, the page order table created in S131 is compared with the second old page order table stored in the second old page order table storage area 333 (S132). Then, by comparing the two page order tables, if the order of the electronic paper 5 is not different, that is, if the electronic paper 5 is not turned over (S132: NO), it is determined that the turning has been completed, The page turning number is calculated by comparing the first old page order table stored in the page order table storage area 332 with the page order table stored in the page order table storage area 331, and the page turning number storage area. 343 is stored (S133). Specifically, the identification information of the electronic paper 5 whose paper page number is “1” in the first old page order table is read, and the paper of the electronic paper 5 of the identification information in the current page order table is read. The page number is read out. A value obtained by subtracting “1” from the paper page number is used as the page turning number. At this time, the maximum page number is stored as the number of connected papers in the connected paper number storage area 330, and the process returns to the original process that called the book turning number calculation process.

  If the order of the electronic paper 5 is different in S132, that is, if the user continues to turn the electronic paper 5 (S132: YES), the process waits for 1 second (S134) and returns to S124.

  In S125, the current page order table is compared with the first old page order table. If the order of the electronic paper 5 is not different, that is, if the electronic paper 5 is not turned (S125: NO), After waiting for one second (S126), it is determined whether 10 minutes have elapsed from the time acquired in S121 (S127). If 10 minutes have passed (S127: NO), the process returns to S124, the current page order table is created again (S124), and compared with the first old page order table (S125). If the electronic paper 5 is turned, it is determined in S125 that the two page order tables are different (S125: YES), and the process proceeds to S129. If the electronic paper 5 is not turned (S125: NO), The processes of S124 to S127 are repeated. Then, when the page turning number calculation process is started and 10 minutes have elapsed from the time acquired in S121 (S127: YES), the page turning number is stored as “0” in the turning number storage area 343 (S128). Then, the turning number calculation process ends, and the process returns to the original process that called the final turning number calculation process.

  In the main process shown in FIG. 21, when the turn count calculation process (S7) is completed, the calculated turn count is “1”, and it is determined whether or not the selection for displaying the previously selected content has been performed. Performed (S8). If the number of turns is “1” (S8: YES), the content displayed last time, that is, the content stored in the display content storage area 338 may be displayed, and the process proceeds to S10 without doing anything. On the other hand, if the number of turns is not “1” (S8: NO), it means that content other than the previously selected content is to be displayed, and content selection processing is performed (see S9).

  Here, the content selection process (S9) will be described with reference to the flowchart of FIG. In the content selection process, first, table of contents information for creating a table of contents page is created (S31). Here, the table of contents information for creating the contents table of contents and the table of contents information for creating the chapter table of contents page of the first chapter of each content are created.

  Specifically, for the content table of contents page, the name of the content stored in the memory card 38 is read and stored in the name 3341 of the table of contents information storage area 334. Then, the number of connected papers stored in the connected paper number storage area 330 is compared with the number of content names read (number of contents). When the number of contents is larger than “number of connected papers−1”, the content table of contents pages is two. Therefore, the first “number of connected papers−2” content has “1” in the item number 3342. Is memorized. Then, “2” is stored in the item number 3342 in the next content corresponding to “number of connected papers−2”. If the number is greater than “(number of connected papers−2) * 2”, the third content table of contents is required. 3 "is stored. Thus, item numbers are assigned according to the number of connected papers and the number of contents. Then, the number of turns of “1” to “number of connected papers−1” is assigned to each content name. If the item number 3342 is “2” or more, the next content table of contents page is displayed on the last electronic paper 5, and therefore, the number of turns from “1” to “number of connected papers−2” is assigned. . Here, the maximum item number is stored in the maximum item number storage area 335.

  Further, the chapter information of the content stored in the memory card 38 is read for the chapter table of contents page. When the number of chapters is larger than “number of connected papers−1”, the names of chapters corresponding to the first “number of connected papers−2” are stored in the name 3341, and from “number of connected papers−1”. If not, the names of chapters corresponding to the first “number of connected papers−1” are stored in the name 3341. Then, “1” is stored in the item number 3342, and the number of turns is sequentially assigned.

  Then, it is determined whether or not there is an item number “1” or more in the table of contents information of the contents table of contents data (S32). If there is no item number “1” or more (S32: NO), there is only one content table of contents page. Therefore, the table of contents information about the contents table of contents in the table of contents information storage area 334 is read, a contents table of contents page is created, and displayed on the display unit 36 of the electronic paper 5 with the page number “1” (S33). Then, the table of contents information about the chapter table of contents page of each content is read out, the first chapter table of contents page is created, and the electronic paper 5 with the paper page number “2” to “maximum page number (number of connected papers)”. (S34).

  Then, in order to determine whether or not the display device 1 is still being used by the user, the current time is acquired from the timing device 51 and stored in the measurement start time storage area 337 (S35). Then, it is determined whether or not the output value of the acceleration sensor 50 has changed (S36). In this case, the threshold at which the measured value of the acceleration sensor 50 is determined to have changed compared to the previous time is assumed to be a case where the difference in acceleration converted from the measured value is 1 G or more. Then, if the output value of the acceleration sensor 50 has changed (S36: YES), a turning number calculation process for calculating the number of pages of the electronic paper 5 is performed (S38, see FIG. 27). When the number of pages turned by the turning calculation process is calculated, the name of the content having the item number “1” and the number of turning calculated in S38 is read out in the table of contents information storage area 334, and stored in the display content storage. It is stored in the area 338 (S51). Then, the process returns to the main process.

  On the other hand, if the output value of the acceleration sensor 50 has not changed (S36: NO), the process proceeds to S37, where it is determined whether 10 minutes have passed since the time of S35 (S37), and 10 minutes have passed. If not (S37: NO), the process returns to S36, and the change of the output value of the acceleration sensor 50 is determined again (S36). Then, the processes of S36 and S37 are repeated, and when 10 minutes have elapsed (S37: YES), it is determined that the user has placed the display device 1, that is, the user is not willing to browse, and this content selection process To return to the main process. That is, the content to be displayed is not selected, and the content in which the previously selected content is stored in the display content storage area 338 is stored as it is.

  If it is determined in S32 that the item number is greater than “1” (S32: YES), there are a plurality of content table of contents pages. Therefore, information about the content table of contents item number “1” in the table of contents information storage area 334 is read out, a content table of contents page is created, and displayed on the display unit 36 of the electronic paper 5 with the page number “1”. (S41). Then, the table of contents information about the chapter table of contents page of each content is read out, the first chapter table of contents page is created, and the electronic data of paper page number “2” to “maximum page number (number of connected papers) −1” It is displayed on the display unit 36 of the paper 5 (S42). Then, information about the content table of contents item number “2” in the table of contents information storage area 334 is read out and displayed on the display unit 36 of the electronic paper 5 with the page number “maximum page number” (S43).

  Then, in order to measure the time for determining whether or not the display device 1 is still used by the user, the current time is acquired from the time measuring device 51 and stored in the measurement start time storage area 337 (S44). ). Then, it is determined whether or not the output value of the acceleration sensor 50 has changed (S45). In this case, the threshold at which the measured value of the acceleration sensor 50 is determined to have changed compared to the previous time is assumed to be a case where the difference in acceleration converted from the measured value is 1 G or more. Then, if the output value of the acceleration sensor 50 has changed (S45: YES), a turning number calculation process for calculating the number of pages of the electronic paper 5 is performed (S47, see FIG. 27). When the number of pages turned by the turning calculation process is calculated, first, the first electronic paper 5 of the page order table stored in the page order table storage area 331 is replaced with the old page of the first old page order table storage area 332. Whether or not the last page, that is, the content table of contents with the item number “2” is opened is determined based on whether or not the electronic paper 5 is in the last order (10th in the above example) in the order table ( S48).

  Therefore, if the last electronic paper 5 has not been opened (S48: NO), the name of the content having the item number “1” in the table of contents information storage area 334 and the number of turns calculated in S38. 3341 is read and stored in the display content storage area 338 (S51). Then, the process returns to the main process. In the example of the table of contents information storage area 334 shown in FIG. 7, the state of the content table of contents page 501 shown in FIG. 8 is displayed in the foreground (the schematic diagram 600 shown in FIG. 12), and the state of the schematic diagram 620 shown in FIG. If it is turned over, the number of turns is “5-1 = 4”, the number of turns is “4”, and the name 3341 stored in the number of turns 3343 in the table of contents information storage area 334 is “How to make delicious tea”. Is stored in the display content storage area 338 as the selected content.

  On the other hand, when the last electronic paper 5 is opened (S48: YES), it is necessary to update the display unit 36 of the other electronic paper 5 based on the information of the next content table of contents page. Therefore, for all content information stored in the table-of-contents information storage area 334, “1” is subtracted from the item number value (S49), and the content for which the item number value is “0” The number is replaced with the maximum item number stored in the maximum item number storage area 335 (S50). Then, the process returns to S41, information about the content table of contents item number “1” in the table of contents information storage area 334 is read, a content table of contents page is created, and the display unit 36 of the electronic paper 5 with the page number “1” is created. (S41). Then, the chapter table of contents page of the item number 3342 of “1” is displayed on the display unit 36 of the electronic paper 5 of the paper page number “2” to “maximum page number (number of connected papers) −1”. (S42). Then, the information about the content table of contents page 3342 having the item number 3342 of “2” in the table of contents information storage area 334 is read and displayed on the display unit 36 of the electronic paper 5 having the page number “maximum page number” (S43). ).

  In the example of the table of contents information storage area 334 shown in FIG. 7, the content table of contents page 501 shown in FIG. When the screen is turned to the forefront (S48: YES), the content table of contents page 502 (FIG. 9) for the content whose item number is changed from “2” to “1” is displayed on the front (S49). Is displayed (S42), and the item number is changed from "1" to "0" (S49) and from "0" to the maximum item number "2" in the last tenth page (S50). Contents table of contents page 501 (FIG. 8) is displayed (S43). This state is the state of the schematic diagram 610 shown in FIG. 13, but is described here with the original item numbers for convenience.

  If the electronic paper 5 on which the chapter table of contents page is displayed is opened (S45: YES, S47, S48: NO), the content is stored in the display content storage area 338 (S51), and the process returns to the main process. . When the last electronic paper 5 is opened (S48: YES), the display unit 36 of the other electronic paper 5 is updated based on the information on the content table of contents item number 3342 is “2”. (S49, S50, S42, S43). Here, when the maximum item number stored in the maximum item number storage area 335 is “2”, the first content table of contents is displayed again, but the maximum item number is “3” or more. If there is, the third content table of contents is displayed.

  If the output value of the acceleration sensor 50 has not changed (SS45: NO), the process proceeds to S46, where it is determined whether 10 minutes have elapsed since the time of S44 (S46), and 10 minutes have passed. If not (S46: NO), the process returns to S45, and the change of the output value of the acceleration sensor 50 is determined again (S45). Then, the processes of S45 and S46 are repeated, and when 10 minutes have elapsed (S46: YES), it is determined that the user has placed the display device 1, that is, the user is not willing to browse, and this content selection process To return to the main process. That is, the content to be displayed is not selected, and the content in which the previously selected content is stored in the display content storage area 338 is stored as it is.

  As described above, it is possible to select the content to be displayed by turning the number of pages of electronic paper 5 described in the content table of contents page.

  Then, as shown in FIG. 21, in the main process, when the content selection process ends (S9), the current time is obtained from the time measuring device 51 in order to determine whether or not the display device 1 is still used by the user. It is acquired and stored in the measurement start time storage area 337 (S10). It is determined whether or not the output value of the acceleration sensor 50 has changed (S11). In this case, the threshold at which the measured value of the acceleration sensor 50 is determined to have changed compared to the previous time is assumed to be a case where the difference in acceleration converted from the measured value is 1 G or more. If the output value of the acceleration sensor 50 has changed (S11: YES), chapter selection processing is performed (S13, see FIG. 23). On the other hand, if the output value of the acceleration sensor 50 has not changed (S11: NO), the process proceeds to S11, where it is determined whether 10 minutes have elapsed since the time of S10 (S12), and 10 minutes have elapsed. If not (S12: NO), the process returns to S4, and the change of the output value of the acceleration sensor 50 is determined again (S11). Then, the processes of S11 and S12 are repeated, and when 10 minutes have elapsed, it is determined that the user has placed the display device 1, that is, does not intend to browse (S12: YES), and the process proceeds to S18.

  Here, the chapter selection process (S13) will be described with reference to the flowchart of FIG. First, it is determined whether or not the value of X is “0” (S61). This variable X has an initial value of “0”, and “1” is stored when the content of the chapter is displayed on the electronic paper 5 by performing a display content conversion process (S17, see FIG. 26) described later. Is done. Since the initial value is “0” (S61: YES), the table of contents information for creating the chapter table of contents page is created (S62).

  Specifically, the name of the chapter of the content stored in the memory card 38 is read and stored in the name 3341 of the table of contents information storage area 334. Then, the number of connected papers stored in the connected paper number storage area 330 is compared with the number of chapter names read out (the number of contents). When the number of chapters is larger than “number of connected papers−1”, the content table of contents pages is 2, so that “1” is added to the item number 3342 for the first “number of connected papers−2” content. Is memorized. Then, “2” is stored in the item number 3342 in the next content corresponding to “number of connected papers−2”. If the number is greater than “(number of connected papers−2) * 2”, the third content table of contents is required. 3 "is stored. Thus, item numbers are assigned according to the number of connected papers and the number of contents. Then, the number of turns of “1” to “number of connected papers−1” is assigned to each content name. If the item number 3342 is “2” or more, the next content table of contents page is displayed on the last electronic paper 5, and therefore, the number of turns from “1” to “number of connected papers−2” is assigned. . Here, the maximum item number is stored in the maximum item number storage area 335.

  Then, it is determined whether or not there is an item number 3342 of “1” or more in the table of contents information (S63). If there is no item number 3342 of "1" or more (S63: NO), there is only one content table of contents page. Therefore, a first display process is performed (S64, see FIG. 24).

  In the first display processing, as shown in FIG. 24, first, information on the chapter table of contents page in the table of contents information storage area 334 is read out, a chapter table of contents page is created, and the electronic paper 5 with the paper page number “1” is created. It is displayed on the display unit 36 (S91). Then, the first page image of each chapter is developed as a sample page image in the sample page development area 340, and the display section of the electronic paper 5 with the paper page number “2” to “maximum page number (number of connected papers) −1”. A sample page of each chapter, that is, an image of the first page in the present embodiment is displayed in 36 (S92). Then, a message indicating the shift to the content selection process such as “Move to contents index page” is displayed on the display unit 36 of the electronic paper 5 with the paper page number “maximum page number” (S93). Then, the process returns to the chapter selection process.

  Next, in order to determine whether or not the display device 1 is still used by the user, the current time is acquired from the time measuring device 51 and stored in the measurement start time storage area 337 (S65). Then, it is determined whether or not the output value of the acceleration sensor 50 has changed (S66). In this case, the threshold at which the measured value of the acceleration sensor 50 is determined to have changed compared to the previous time is assumed to be a case where the difference in acceleration converted from the measured value is 1 G or more. Then, if the output value of the acceleration sensor 50 has changed (S66: YES), a turning number calculation process for calculating the number of pages of the electronic paper 5 is performed (S68, see FIG. 27).

  When the number of pages turned by the turning calculation process is calculated, first, the first electronic paper 5 of the page order table stored in the page order table storage area 331 is stored in the first old page order table storage area 332. Whether or not the display unit 36 displaying the message of transition to the last page, that is, the content selection process is opened depending on whether or not the electronic paper 5 is in the last order (10th in the above example) in the old page order table. Is determined (S79). If the last page has been opened (S79: YES), content selection processing is performed (S80, see FIG. 22). After the content is selected again, the process returns to S62, and chapter selection in the content is performed. Will be done.

  On the other hand, if the last page has not been opened (S79: NO), in the table of contents information storage area 334, the name of the chapter whose item number 3342 is “1” and the number of turns is the number calculated in S68 is read. It is stored in the display chapter storage area 339, and the image of the page of the selected chapter is developed in the display image development area 341. Then, the images after the second page among the developed images are sequentially displayed on the display unit 36 of the electronic paper 5 with the paper page numbers “2” to “maximum page number” (S81). Then, the process returns to the main process. In S 81, the total number of pages of the selected chapter is stored in the total page number storage area 342 of the RAM 33.

  In the example of the chapter table of contents page 503 shown in FIG. 10, as shown in the schematic diagram 630 shown in FIG. When the sample page 504 (FIG. 11) in Chapter 1 is brought to the forefront (S75, S76: NO, S79: NO) as shown in FIG. The second and subsequent pages are sequentially displayed (S81).

  On the other hand, if the output value of the acceleration sensor 50 has not changed (S66: NO), the process proceeds to S67, where it is determined whether 10 minutes have passed since the time of S65 (S67), and 10 minutes have passed. If not (S67: NO), the process returns to S66, and the change of the output value of the acceleration sensor 50 is determined again (S66). Then, the processes of S66 and S67 are repeated, and when 10 minutes have elapsed (S67: YES), it is determined that the user has placed the display device 1, that is, the user is not willing to browse, and the chapter selection process is performed. End and return to the main process. That is, the display unit 36 is not updated, and the chapter table of contents page and the sample page remain displayed.

  If it is determined in S62 that the item number 3342 is greater than “1” (S63: YES), there are a plurality of chapter table of contents pages. Therefore, a second display process is performed (S71, see FIG. 25).

  In the second display process, as shown in FIG. 25, first, information on the chapter table of contents page in the table of contents information storage area 334 is read out, a chapter table of contents page is created, and the electronic page 5 with the paper page number “1” is created. It is displayed on the display unit 36 (S96). Then, the first page image of each chapter is developed as a sample page image in the sample page development area 340, and the display section of the electronic paper 5 with the paper page number “2” to “maximum page number (number of connected papers) −2”. 36 shows a sample page of each chapter, that is, the image of the first page in the present embodiment (S97). Then, a chapter table of contents item number 3342 of “2” is displayed on the display unit 36 of the electronic paper 5 of “maximum page number (number of connected papers) −1” (S98). Then, on the display unit 36 of the electronic paper 5 with the paper page number “maximum page number”, a message indicating the shift to the content selection process such as “I will move to the contents selection index page” is displayed (S99). Then, the process returns to the chapter selection process.

  Then, in order to determine whether or not the display device 1 is still used by the user, the current time is acquired from the time measuring device 51 and stored in the measurement start time storage area 337 (S72). Then, it is determined whether or not the output value of the acceleration sensor 50 has changed (S73). In this case, the threshold at which the measured value of the acceleration sensor 50 is determined to have changed compared to the previous time is assumed to be a case where the difference in acceleration converted from the measured value is 1 G or more. If the output value of the acceleration sensor 50 has changed (S73: YES), a turning number calculation process for calculating the number of pages of the electronic paper 5 is performed (S75, see FIG. 27). When the number of pages turned by the turning calculation process is calculated, first, the first electronic paper 5 of the page order table stored in the page order table storage area 331 is transferred to the old page of the first old page order table storage area 332. Whether or not the last page, that is, the content table of contents with the item number 3342 of “2” is opened depending on whether or not the electronic paper 5 is in the order (9th in the above example) immediately before the end of the order table. Is made (S76).

  Therefore, when the electronic paper 5 immediately before the last is not opened (S76: NO), the first electronic paper 5 in the page order table stored in the page order table storage area 331 is the first electronic paper 5. A display that displays a message for shifting to the last page, that is, the content selection process, depending on whether or not the electronic paper 5 is in the last order (10th in the above example) in the old page order table in the old page order table storage area 332. It is determined whether the part 36 is opened (S79). If the last page has been opened (S79: YES), content selection processing is performed (S80, see FIG. 22). After the content is selected again, the process returns to S62, and chapter selection in the content is performed. Will be done.

  On the other hand, if the last page has not been opened (S79: NO), in the table of contents information storage area 334, the name of the chapter whose item number 3342 is “1” and the number of turns is the number calculated in S68 is read. It is stored in the display chapter storage area 339, and the image of the page of the selected chapter is developed in the display image development area 341. Then, the images after the second page among the developed images are sequentially displayed on the display unit 36 of the electronic paper 5 with the paper page numbers “2” to “maximum page number” (S81). Then, the process returns to the main process. In S 81, the total number of pages of the selected chapter is stored in the total page number storage area 342 of the RAM 33.

  On the other hand, when the electronic paper 5 immediately before the last is opened (S76: YES), it is necessary to update the display unit 36 of the other electronic paper 5 based on the information of the next content table of contents page. is there. Therefore, with respect to the information of all contents stored in the table of contents information storage area 334, “1” is subtracted from the value of the item number 3342 (S77), and the content for which the value of the item number 3342 is “0”. The item number is replaced with the maximum item number stored in the maximum item number storage area 335 (S78). Then, the process returns to S71, the second display process is performed (S73), and the display unit 36 of the other electronic paper 5 is updated based on the information on the chapter table of contents page whose item number 3342 is “1” ( S77, S78, S71). If the maximum item number is “2”, the first chapter table of contents page is displayed again. If the maximum item number is “3” or more, the third chapter table of contents page is displayed. Will be displayed.

  As described above, the chapter to be displayed can be selected by turning the turning-number electronic paper 5 described in the chapter table of contents page. Furthermore, since the first page image is displayed as a sample page on the display unit 36 that is turned over, the user can easily determine whether or not the information is the information he / she wants to browse. Then, since the page following the sample page is displayed in accordance with the display section 36 after the electronic paper 5 in the next order of the sample page, when the user selects the sample page, he browses the information as it is and turns the page. You can browse the following information by the natural movement.

  As shown in FIG. 21, in the main process, when the chapter selection process ends (S13), the current time is acquired from the time measuring device 51 in order to determine whether the display device 1 is still used by the user. Then, it is stored in the measurement start time storage area 337 (S14). It is determined whether or not the output value of the acceleration sensor 50 has changed (S15). In this case, the threshold at which the measured value of the acceleration sensor 50 is determined to have changed compared to the previous time is assumed to be a case where the difference in acceleration converted from the measured value is 1 G or more. If the output value of the acceleration sensor 50 has changed (S15: YES), display content conversion processing is performed (S17, see FIG. 26). On the other hand, if the output value of the acceleration sensor 50 has not changed (S15: NO), the process proceeds to S15, where it is determined whether 10 minutes have passed since the time of S14 (S16), and 10 minutes have passed. If not (S16: NO), the process returns to S15, and the change of the output value of the acceleration sensor 50 is determined again (S15). Then, the processes of S15 and S16 are repeatedly performed, and when 10 minutes have elapsed (S16: YES), it is determined that the user has placed the display device 1, that is, the user is not willing to browse (S16: YES). , Go to S18.

  Here, the display content conversion processing will be described with reference to the flowchart of FIG. First, “1” is stored in the variable X (S100). The variable X is a variable indicating whether or not the display content conversion process has been performed. Then, in order to determine whether or not the electronic paper 5 is still used by the user, the current time is acquired from the timing device 51 and stored in the measurement start time storage area 337 (S101). It is determined whether or not the output value of the acceleration sensor 50 has changed (S102). In this case, the threshold at which the measured value of the acceleration sensor 50 is determined to have changed compared to the previous time is assumed to be a case where the difference in acceleration converted from the measured value is 1 G or more. If the output value of the acceleration sensor 50 has changed (S102: YES), it means that the user is still browsing the display device 1, and thus the turning number calculation process is performed (S105, see FIG. 27).

  On the other hand, if the output value of the acceleration sensor 50 has not changed (S102: NO), the process proceeds to S103, where it is determined whether 10 minutes have passed since the time of S101 (S103), and 10 minutes have passed. If not (S103: NO), the process returns to S102, and the change of the output value of the acceleration sensor 50 is determined again (S102). Then, the processes of S102 and S103 are repeated, and when 10 minutes have elapsed (S103: YES), it is determined that the user has placed the display device 1, that is, the user is not willing to browse. "0" is stored (S104), the process is terminated, and the process returns to the main process.

  If there is a change in the output value of the acceleration sensor 50 (S102: YES) and the turning number calculation process is performed (S105), the first electronic paper 5 (in the page order table stored in the page order table storage area 331) ( It is determined whether or not the content displayed on the foreground electronic paper 5) is blank (S106). When information indicating “blank” is stored in the displayed document content whose paper page number is “1” (S106: YES), the page of the chapter is completed (schematic diagram in FIG. 19). 670, see the schematic diagram 680 in FIG. 20), chapter selection processing is performed (S111, see FIG. 23), the chapter to be displayed next is selected, and the process returns to S101.

  On the other hand, if no white paper is displayed on the foreground electronic paper 5 (S106: NO), it is determined whether there is an image of a page that is not yet displayed on the electronic paper 5 (S107). Specifically, the largest page among the information stored in the displayed document content of the page order table stored in the page order table storage area 331 and the page number stored in the total page number storage area 342. The number is compared. Therefore, if there is no page that is not displayed (S107: NO), there is no need to update the display, and the process directly returns to S102.

  On the other hand, when there is a page that is not displayed (S107: YES), it is necessary to display the image of the subsequent page. Therefore, it is determined whether or not the number of turning pages calculated by the turning number calculating process in S105 is larger than the number of subsequent pages (S108). If the number of turning pages is not larger than the number of continuous pages (S108: NO), the image of the page can be displayed on all the turned electronic papers 5. Then, the image of the subsequent page among the images developed in the display image development area 341 is displayed (S109). Then, the process returns to S102. For example, when one electronic paper 5 is turned from the state shown in the schematic diagram 650 of FIG. 17, the number of turned pages “1” is not larger than the number of subsequent pages “12-10 = 2” (S108: NO), as shown in the schematic diagram 660 of FIG. 18, the image of the 11th page following the turned electronic paper 5 (identification number “S21121”) is displayed (S109).

  If the number of pages to be turned is larger than the number of pages to be continued (S108: YES), images of successive pages among the images developed in the display image development area 341 are displayed in order on the turned-up display unit. Then, a blank image is displayed on the display unit 36 of the electronic paper 5 on which the image of the subsequent page is not displayed (S110). Then, the process returns to S102. For example, when three sheets of electronic paper 5 are turned from the state shown in the schematic diagram 660 of FIG. 18, the number of turned pages “3” is larger than the number of subsequent pages “12-11 = 1” (S108: YES). ), As shown in the schematic diagram 670 of FIG. 19, the image of the subsequent 12th page is displayed in the identification number “S47613” of the turned electronic paper 5, but the remaining two electronic papers 5 (identification) Blank pages are displayed for the numbers “S40112” and “S00134”.

  The turned-up electronic paper 5 is stored in the page order table storage area 331 from the first electronic paper 5 of the previous page order table stored in the first old page order table storage area 332. This is the electronic paper 5 up to the electronic paper 5 in the last order of the current page order table. For example, in the case where the schematic diagram 660 shown in FIG. 18 is turned to the state of the schematic diagram 670 shown in FIG. 19, the three electronic papers 5 are turned in the order of the schematic diagram 660. In this case, from the first electronic paper 5 in the previous page order table, that is, the electronic paper 5 whose identification information is “S47613”, the last electronic paper 5 in the current page order table, that is, the identification information is “ Three sheets up to the electronic paper 5 of S00134, that is, the electronic paper 5 in which the electronic paper 5 of identification information “S47613”, “S40112”, and “S00134” is turned.

  When the process returns to S102, the turning of the next electronic paper 5 is detected and the number of turns is calculated (SS102, S103, S105), and based on the image displayed on the first electronic paper 5 after the turning. A chapter selection process is performed (S111), and an image of a page following the turned electronic paper 5 is displayed (S107 to S110). When such processing is repeated and the display device 1 is placed by the user and the display device 1 is not moved for 10 minutes or more, this processing ends and returns to the main processing.

  Then, as shown in FIG. 21, when returning to the main process, the first table of contents page of the content stored in the display content storage area 338 is displayed on the display unit 36 of the first electronic paper 5 (S18). ), The power supply is set to the sleep state (power saving) (S19), and the process proceeds to S1. Then, it is continuously monitored whether the output value of the acceleration sensor 50 changes (S1: NO, S1).

  As described above, when the electronic paper 5 is turned by the user, successive pages are displayed in order, so that the user can browse information by a natural operation of turning the page. Also, blank paper is displayed on the electronic paper 5 in the order after the electronic paper 5 on which the image of the last page is displayed (S110). If the blank electronic paper 5 is opened (S106: YES), it is again displayed. Since the chapter can be selected (S111), the user can continuously browse the subsequent chapters.

  If another content is to be browsed, the blank electronic paper 5 is displayed on the forefront (S106: YES). Then, the process proceeds to the chapter selection process (S111), the chapter table of contents page is displayed on the foremost electronic paper 5 (S91 or S96), and the last electronic paper 5 displays a message for shifting to the content selection process (S93). Alternatively, when the user opens the electronic paper 5 on which this message is displayed (S79: YES), the process proceeds to a content selection process (S80), and a content table of contents page is displayed (S41 or S33). Therefore, even when the user is browsing the chapter information, the user can easily select another content.

  In this way, by turning the electronic paper 5, it is possible to select contents and chapters, and therefore it is not necessary to provide input means such as buttons and a touch panel on the display device 1, thereby reducing costs. In addition, when the buttons are provided, the area of the display unit is reduced accordingly, or the display device 1 is enlarged. However, by turning the electronic paper 5, the contents can be selected or the saving can be selected. , The buttons should not get in the way. In addition, there is no case where the user touches the button by mistake and makes an erroneous operation.

  Further, by monitoring the output value of the acceleration sensor 50, it is determined whether the user has placed the display device 1 (S5, S6, S11, S12, S15, S16 of the main process, content selection process). S36, S37, S45, S46, chapter selection processing S66, S67, S73, S74, display content conversion processing S102, S103), and if the user has left the display device 1, the power is set to sleep. (S19 of the main process). Then, the output value of the acceleration sensor 50 is continuously monitored (S1 of the main process). When the display device 1 is moved (S1: YES), it is assumed that the user holds the display device 1 and the process is performed. Is resumed. Therefore, when the user has left the display device, power is not consumed and power is saved.

  Note that the master paper 3 in the above embodiment corresponds to an “output device”, the memory card 38 corresponds to a “unit information storage unit”, the acceleration sensor 50 corresponds to a “movement detection unit”, and the voltage measurement unit 48 Corresponds to “voltage measuring means”. The content table of contents page, chapter table of contents page, and sample page (first page image) correspond to “representative images”. The position detection ring 24 is used when creating the current page order table in S124 and S131 of the main process (FIG. 21) for creating the page order table in S2 and the turning number calculation process (FIG. 27). The CPU 31 that performs the inquiry process for the positions in the ring from 0 to 255 and receives the response of the serial number from the slave paper 4 corresponds to the “position information acquisition unit”. Then, in S124 and S131 of the page order table of S2 in the main process of FIG. 21 and the turning number calculation process (FIG. 27), the serial number and the position in the ring returned from the slave paper 4 are displayed in the page order table. The CPU 31 that performs the process of storing and sorting at the position in the ring corresponds to “order determination means”.

  Then, the CPU 31 that performs the processing of S34 and S42 of the content selection processing of FIG. 22, the processing of S92 of the first display processing of FIG. 24, and the processing of S97 of the second display processing of FIG. 25 becomes “representative image display control means”. Equivalent to. The CPU 31 that performs the processes of S36 to S38 and S45 to S48 of the content selection process of FIG. 22 and the processes of S66 to S68 and S73 to S76 of the chapter selection process of FIG. 23 corresponds to the “front-most display means determination unit”. . 23, the process of S81 of the chapter selection process of FIG. 23, the process of S92 of the first display process of FIG. 24, the process of S97 of the second display process of FIG. 25, and the processes of S106 and S111 of the display content conversion process of FIG. The CPU 31 performing the process corresponds to “rewriting means”. Then, the CPU 31 performs the processes of S31, S33, and S41 of the content selection process of FIG. 22, S62 of the chapter selection process of FIG. 23, S91 of the first display process of FIG. 24, and S96 and S98 of the second display process of FIG. Corresponds to “table of contents page creation means”. The CPU 31 that performs the processing of S33 and S41 of the content selection process of FIG. 22, the S91 of the first display process of FIG. 24, and the S96 and S98 of the second display process of FIG. 25 corresponds to the “contents page display control means”. . And CPU31 which performs the process of S102, S103, and S105 of the display content conversion process of FIG. 26 is equivalent to a "turning detection means." And CPU31 which performs S109 and S110 of the display content conversion process of FIG. 26 is equivalent to a "turning rewriting means." Then, the CPU 31 that performs the processing of S62 of the chapter selection process of FIG. 23, S91 of the first display process of FIG. 24, and S96 and S98 of the second display process of FIG. 25 corresponds to “lower table of contents page creation means”.

  It should be noted that the display device and output device of the present invention are not limited to the above-described embodiments, and it goes without saying that various changes can be made without departing from the scope of the present invention. In the above embodiment, the unit information to be displayed on the display device 1 has two levels of “content” and “chapter”. When the information displayed on the display device 1 is only one content, only “chapter” may be used as unit information. Further, unit information such as “paragraph” may be further provided under “chapter” to deepen the hierarchy. In this case, in the main process, after the chapter selection process (S13), it is determined whether or not the display device 1 has not been moved for more than 10 minutes (the same process as S5, S6, S11, and S12). ), Followed by “paragraph selection processing”. This paragraph selection process has the same flow as the chapter selection process. When the paragraph table of contents page is used instead of the chapter table of contents page and the last page is opened (S79: YES), the content selection process is performed. Instead of proceeding to, proceed to chapter selection processing. The sample page is an image of the first page of each paragraph. Further, in the chapter selection process, a paragraph table of contents page is displayed instead of the sample page.

  In the above embodiment, “content” is always composed of “chapter”, but “content” without “chapter” may exist. That is, the depth of the hierarchy may be different for each “content”. In this way, when the depth of the unit information hierarchy is not constant, in the content selection process, the chapter table of contents page is not displayed on the electronic paper 5 behind the content table of contents page, but one page of the content as a sample page. An image of the eye will be displayed. That is, in the processing of S34 and S42 shown in FIG. 22, it is determined whether or not the content is composed of lower-level lower-level unit information, that is, “chapter” (the CPU 31 that performs this processing determines “lower-level determination means”). ”), If it is not composed of lower unit information, the first page image is displayed as a sample page. Then, in the case of being composed of lower unit information, the chapter table of contents page is displayed as in the example shown in FIG. Further, in the chapter selection process, first, it is determined whether or not the content stored in the display content storage area 338 is configured with lower unit information, and is not configured with lower unit information. Are displayed in order on the second and subsequent electronic papers 5, and the chapter selection process ends. If the unit information is composed of lower unit information, the processes of S31 to S51 shown in FIG. 22 are performed.

  Further, in the above embodiment, when a blank sheet is displayed on the electronic paper 5 that is later than the electronic paper 5 on which the image of the last page of the chapter is displayed, and the electronic paper 5 on which the blank sheet is displayed is opened, A chapter table of contents page is displayed on the electronic paper 5. In addition to this, when the page order table is created, the chapter table of contents page (the chapter table of contents page stored in the display content storage area 338) is always displayed on the display unit of the electronic paper 5 in the last order. You may do it. As a result, even if the electronic paper 5 is not dimmed to the last page of the chapter, the chapter table of contents page can be opened on the last electronic paper 5 at any time to display another chapter or to select another content. The content table of contents page can be displayed.

  In the above embodiment, the chapter content page is used as the representative image. However, the representative image for selecting unit information is not the table of contents page of unit information in the lower hierarchy, but the first page of unit information. It may be an image. Moreover, the sentence and summary which appeal the content may be memorize | stored for every unit information, and the image of the information may be displayed.

  In the above embodiment, the display unit 36 is provided on only one side of the electronic paper 5. However, the display unit 36 may be provided on both sides of the electronic paper 5.

  Further, in the above embodiment, when the electronic paper 5 is turned, the image of the subsequent page is displayed immediately on the display unit 36 of the turned electronic paper 5 in S109 or S110. Only when the number of papers 5 reaches a certain number or more, an image of a subsequent page may be displayed on the display unit 36 of the turned electronic paper 5. In this case, even if it is determined in S107 that there is a page that is not displayed (S107: YES), the processing in S108 to S110 is not performed unless the number of repetitions calculated in S105 is greater than or equal to the predetermined number. The number of pages turned over is stored (the total number of pages turned over), and the process returns to S102. Then, when the electronic paper 5 is turned over again, S107 is performed, and when it is determined that there is a page that is not displayed, the number of turnovers calculated in S105 is added to the turnover number total counter. If the number is equal to or greater than the predetermined number, the processing of S108 to S110 may be performed. Further, if the value of the turning counter is not more than the predetermined number, the calculation is made in S105, and it is only necessary to add the turning number to the turning counter and return to S102. Note that the turn total counter is given an initial value “0” at the start of the main processing, and is initialized to “0” when it is determined that the number is equal to or greater than a predetermined number.

  In the above embodiment, the rings 21 to 24 have been described as having an O-shape. However, the rings 21 to 24 have other through-holes that pass through the through holes 11 to 14 of the electronic paper. It may be a shape. For example, it may be D-shaped.
