FIG. 18 is a flowchart of a multi-page position detection process executed in the master paper main process.

  First, as shown in FIG. 7, in the master paper main process, the position information / identification information of the electronic paper 5 bound to the display device 1 is collected, and the display data of the content stored in the memory card 38 is obtained. The process assigned to each electronic paper 5 is performed. Each time the binding member 2 is opened or closed or page turning is performed, these processes are executed to update the state and repeat the process.

  When the power of the master paper 3 is turned on by a power button (not shown), the master paper main process is started. When the master paper main process is started, the display start content page number is set to 1 and stored in the display start content page number storage area 336 (S10). Next, a paper information collecting process for collecting paper information that is information of the electronic paper 5 bound to the display device 1 is executed (S20). The paper information is information indicating which electronic paper 5 is located where.

  Details of the paper information collection process will be described with reference to FIGS. In the paper information collection process, the serial numbers are sequentially inquired to the slave papers 4 at positions 0 to 255, and the correspondence relationship of which slave paper 4 is located is stored in the page order table.

  As shown in FIG. 8, in the paper information collection process, first, the scan position is set to 0 and initialized. Since the master paper 3 itself is also bound in the display device 1, first, the paper information about the master paper 3 is stored. That is, the number of connected papers is stored as 1 in the connected paper number storage area 331, and the manufacturing number and position information of the master paper 3 are stored in the page order table (S21).

  Next, processing for inquiring the manufacturing number to the slave paper 4 in order from the scanning position of 0 is performed. If there is no slave paper 4 at the inquired scanning position, no response is returned. In that case, timeout processing is performed. For this purpose, first, a timer for waiting for a response is set (S22). Next, the serial number is inquired to the slave paper 4 that may be at the target scanning position (S23). In the present embodiment, data transmission between the master paper 3 and the slave paper 4 is performed using a format such as (destination type, destination position, destination manufacturing number, command, data). Here, for example, a command (S, 0, *, REQID) for inquiring the manufacturing number is transmitted to the scanning position of 0.

  Next, it is determined whether or not a response is obtained from the slave paper 4 for this command transmission (S24). If there is a response (S24: YES), the manufacturing number of the slave paper 4 that has responded is stored in the paper number 3322 of the page order table, and the current scan position is stored in the in-ring position 3324 (S25). . Then, 1 is added to the number of bound electronic papers (the number of connected papers) (S26). On the other hand, if there is no response (S24: NO), the process returns to S24 and repeats the process until a predetermined time elapses and a timeout occurs (S27: NO), and if the timeout occurs (S27: YES), the next scanning position is reached. The process proceeds to (S28).

  When the processing of the target scanning position is completed (S26 or S27: YES), 1 is added to the scanning position to target the next scanning position (S28). Then, S22 to S29 are repeated until the processing is completed up to the scanning position 255 (S29: NO). When the processing is completed for all the scanning positions, the records in the page order table are rearranged in order from the inner position 3324 in ascending order using the inner position 3324 as a key, and the paper page numbers are assigned in order from the inner position 3324 in ascending order. (S30). Since the positions and serial numbers of all the electronic papers in the display device 1 have been collected as described above, the paper information collecting process is terminated and the process returns to the master paper main process. If the in-ring position 3324 of the inquiry destination is 128 in S23, a timeout always occurs in S27. This is because in the present embodiment, the in-ring position 3324 of the master paper 3 is 128, and the in-ring position 3324 of the slave paper 4 is never 128.

  FIG. 9 shows the state of the storage area of the RAM 33 when the paper information collection process is completed. Since 3 is stored in the connected paper number storage area 331, the number of electronic papers currently bound to the display device 1 is 3 including the master paper 3. In the page order table, the information of each of the three electronic papers is arranged in the order in which they are positioned above. The first page is the slave paper 4 with the serial number S00234 at the in-ring position 127, the next is the master paper 3 (the serial number is the serial number). M00001, the position in the ring is 128), and the last page is the slave paper 4 of the production number S04058 at the position 129 in the ring.

  Next, returning to FIG. 7, the description of the master paper main process is continued. Since the paper information collection process has been completed (S20), a page allocation process for assigning content display data to each paper is performed (S40). That is, as shown in FIG. 10, the displayed content page number 3323 is assigned to the displayed content pages 1, 2, and 3 in order from the electronic paper whose paper page number 3321 is 1. Then, 1 is stored in the rewrite start paper page number storage area 337 and 3 is stored in the rewrite page number storage area 338. With this setting, the data display process described below is executed from the first page to all the papers.

  Next, a data display process for displaying the assigned content page on each electronic paper is executed (S50). Here, the data display processing will be described with reference to FIG. First, it is determined whether the number of pages to be rewritten has reached 0 (S51). Until the number of rewritten pages becomes 0 (S51: NO), the following processing is repeatedly executed.

  First, the display data of the displayed content page number (1 in the example of FIG. 10) of the rewriting start paper page number (1 in the example of FIG. 10) is read from the memory card 38 and stored in the page data expansion area 333 ( S52). That is, first, display data for the first page is read in order to display the first page of the display content on the first page of electronic paper.

  Next, it is determined whether or not the manufacturing number of the electronic paper whose page number 3321 is the rewriting start paper page number is the manufacturing number of the master paper 3 itself. If it is the serial number of the master paper 3 itself (S53: YES), the display data is displayed on the display unit 36 of the master paper 3 as it is (S54). In the example of FIG. 10, the production number 3322 of the paper whose page number 3321 is the rewrite start paper page number (= 1) is “S00234” and is not the production number of the master paper 3 (S53: NO). Display data is transmitted to the slave paper 4 (S55). Data transmission in this case is (S, *, S00234, REQWRITE, [display data]). As will be described later, the slave paper 4 that has received this command displays the received display data on the display unit 46 and notifies the display completion, and therefore waits until a response is received (S56).

  Since the display data for the first page is displayed on the first electronic paper as described above, 1 is subtracted from the number of papers to be rewritten (number of rewritten pages) (S57). Then, 1 is added to the rewrite start paper page number in order to display the display data on the next electronic paper 5 (S58). Here, the number of rewritten pages is 2, and the rewrite start paper page number is 2.

  Then, in order to determine whether or not the display has been completed on all the electronic papers in the display device 1, it is determined whether or not the rewriting start paper page number exceeds the number of connected papers (S59). Here, since the number of connected papers is 3 and the rewrite start paper page number is 2, the process returns to S51 to perform display processing on the electronic paper at the next position. In the next processing, since the manufacturing number of the electronic paper whose page number 3321 is the rewriting start paper page number (= 2) is “M0001” and is the manufacturing number of the master paper 3 itself (S53: YES), the page data development is performed. The display data stored in the area 333 is displayed on the display unit 36 as it is (S54). Then, the number of rewritten pages is subtracted to 1 (S57), and the rewriting start paper page number is added to 3 (S58). Thus, the display of the display data for the second page is completed.

  Since the display process has not been completed yet (S59: NO), the process returns to S51 again, and the display process for the next paper is performed. In the next processing, the electronic paper manufacturing number whose paper page number 3321 is the rewriting start paper page number (= 3) is the slave paper 4 of “S04058” (S53: NO). Data is transmitted and displayed (S55). Then, the number of rewritten pages is subtracted to 0 (S57), and the rewriting start paper page number is added to 4 (S58).

  Since the display has been made on all three papers in the display device 1 (the rewrite start paper page number has exceeded the number of connected papers) (S59: YES), the rewrite start paper page number is set to 1 ( S60), the process returns to S51, and since the number of rewritten pages is 0 (S51: YES), the process returns to the master paper main process.

  If there is no display data corresponding to the content page number being displayed in S52, the blank display data is stored in the page data expansion area 333. Further, when a “value linked to screen data indicating the end of content” to be described later is set in the displayed content page number, the screen data indicating the end of content is stored in the page data expansion area 333. When a “value linked to screen data indicating the beginning of content”, which will be described later, is set in the displayed content page number, display data indicating the beginning of the content is stored in the page data expansion area 333. Display data indicating the end of content and display data indicating the beginning of content are stored in the EEPROM 34, respectively. Here, the description will be made assuming that the data is stored in the EEPROM 34, but the display data indicating the end of the content and the display data indicating the head of the content may be stored anywhere.

  Returning to FIG. 7, the description of the master paper main process is continued. Since one to three pages of contents are displayed on each of the three electronic papers 5 in the display device 1 (S50), it is next determined whether or not the binding member 2 has been opened and closed (S70). . As described above, the opening and closing of the binding member 2 is detected by the switch 148 of the position detection ring 24. If it has been opened and closed (S70: YES), there is a possibility that the electronic paper 5 has been added or removed, so the paper information collection process is executed again (S80, FIG. 8), and the updated page order table The page assignment process is performed according to the above, 1 is stored in the rewrite start paper page number storage area 337, and the number of connected papers is set in the rewrite page number storage area 338 (S90). Then, display data is displayed on each electronic paper in accordance with the page order table to which pages have been assigned (S200, FIG. 11).

  If the binding member 2 is not opened or closed (S70: NO), it is checked whether or not page turning has been performed. If page turning has occurred, processing for appropriately rewriting display data on the display units 36 and 46 is performed. (S100 to S200). First, the current page order table stored in the page order table storage area 332 is copied to the display processing work area 335 as an old page order table (S100).

  Next, a paper information collection process is executed to check whether page turning has been performed (S110, FIG. 8). For example, after the execution of S110, the page order table is updated to a state as shown in FIG. In the old page order table, the slave paper 4 of “S00234” in which the in-ring position 3324 is 127 and is the first page (page number 1), and in the page order table, the in-ring position 3324 is 130 and the trailing page (page number 3). Have come to.

  Next, referring to the page order table updated in S110, the position of the first page is confirmed, and the first page position scanning process for preparing to update the display content of the page that has come to the rear end is executed (S120).

  Here, the first page position scanning process will be described with reference to FIG. As shown in FIG. 13, in the first page position scanning process, first, the paper manufacturing number of the first position of the old page order table stored in the display processing work area 335 is set to the scanned paper number to be scanned. (S121). In the example of FIG. 12, scanning paper number = S00234 is set.

  Next, it is determined whether or not the paper page number in the page order table of the paper with the scanned paper number set in S121 is equal to the number of connected papers (S122). The paper of the scan paper number is the paper at the top position of the old page order table, and the number of connected papers is equal to the page number of the last page. If these two values are equal (S122: YES), it is the top page. This means that the displayed page number 3323 to be displayed on the rear end paper of the current page order table is the next page of the paper one page before the rear end paper. The value of the displayed content page number 3323 is updated so as to be a page (S124). In the example of FIG. 12, the value of the displayed content page number 3323 of “S00234” at the rear end is “1”, which is the value next to the value “3” of the displayed content page number 3323 one page before. The page is updated to “4” (see FIG. 14).

  Then, the display start content page number indicating the page number of the content currently displayed on the display device 1 is displayed on the first electronic paper is incremented by 1 and stored in the display start content page number storage area 336. In the example of FIG. 12, the display start content page number is “1”. However, as a result of turning the first page, the content page displayed on the current first page ([M0001]) is the second page. Therefore, the display start content page number is updated to “2” (see FIG. 14).

  Next, it is determined whether or not the displayed content page number to be displayed on the rear end paper of the current page order table is larger than the content page number of the content (S126). When the number is larger than the number of content pages, the first page is turned to the rear end page, but there is no content data to be displayed on the rear end page. In such a case (S126: YES), 1 is stored in the rewrite start paper page number storage area 337 (S129), and "1" is set as the rewrite page number and stored in the rewrite page number storage area 338. In the above (S130), a value linked to the screen data indicating the end of the content is set to the displayed content page number to be displayed on the rear end paper of the current page order table (S131). Then, the process returns to the master paper main process.

  If the content page number being displayed on the trailing edge paper is less than or equal to the number of content pages (S126: NO), the page number of the paper that needs to be rewritten is set as the number of connected papers (S127). Here, since the first paper is turned and moved to the rear end, it is necessary to rewrite the display of the rear end page. Since the paper page number of the rear end page is the same value as the number of connected papers, the rewrite start paper page number is set as the number of connected papers. In the example of FIG. 12, it is desired to display the next page of the content on the paper “S00234” that has been turned and moved from the top (paper page number = 1) to the rear end (paper page number = 3). Therefore, as shown in FIG. 14, 3 is stored in the rewrite start paper page number storage area 337.

  Since the number of papers to be rewritten this time is only the trailing paper, “1” is set as the number of rewritten pages and stored in the rewritten page number storage area 338 (S128), and the process returns to the master paper main process.

  On the other hand, if the paper page number of the scanned paper number and the number of connected papers are not the same value (S122: NO), it is necessary to rewrite the display because the first page has been beaten and not performed at the rear end. Therefore, 0 is set to the number of rewritten pages (S123), and the process returns to the master paper main process.

  Returning to FIG. 7, the description of the master paper main process is continued. Since it is determined in the above first page position scanning process (S120, FIG. 13) whether or not there is a page turn of the first page, it is next determined whether or not there is a page turn based on the result (S140). Specifically, whether or not there is a page turn can be determined by whether or not “1” is stored in the value of the rewritten page number storage area 338 as a result of the first page position scanning process. If there is a page turn (S140: YES), each electronic paper 5 is assigned to each electronic paper 5 according to the page order table updated in S120, the display start content page number, the rewrite start paper page number, and the rewrite page number (see FIG. 14). Display data is displayed (S200, FIG. 11).

  If it is determined that there is no page turning, then it is checked whether page turning has been performed for the trailing edge page, and trailing edge page position scanning processing is performed to prepare for updating the display contents of the page moved to the top. (S150).

  Here, the rear end page position scanning process will be described with reference to FIGS. As shown in FIG. 15, in the trailing edge page position scanning process, first, the manufacturing number of the trailing edge paper stored in the display processing work area 335 is added to the scanning paper number to be scanned. The setting is made (S151). In the example of FIG. 16, scanning paper number = S04058 is set.

  Next, it is determined whether or not the paper page number in the page order table of the paper with the scanned paper number set in S121 is “1” (S152). Since the paper of the scan paper number is the paper at the rear end position of the old page order table, if this is “1” in the current page order table (S152: YES), the paper that was the rear end page is beaten. Since it is the first page, the displayed content page number 3323 to be displayed on the first paper of the current page order table is the page before the second page so that the displayed content page number 3323 is displayed. The value of 3323 is updated (S154). In the example of FIG. 16, the value of the currently displayed content page number 3323 of “S04058” that is currently the head is “6”, but this is the value before the value “4” of the displayed content page number 3323 of the second page. The page is updated to “3” (see FIG. 17).

  Then, the display start content page number indicating which page of the content currently displayed on the display device 1 is displayed on the first electronic paper 5 is reduced by 1, and stored in the display start content page number storage area 336. (S155). In the example of FIG. 16, the display start content page number is “4”, but as a result of the rear end page being turned to the top, the page of the content displayed on the current top page ([S04058]) is the third page. Therefore, the display start content page number is updated to “3” (see FIG. 17).

  Next, it is determined whether or not the display start content page number is smaller than “1” (S156). If the rear end page is turned to the top in the state where the page is displayed from the first page, the display start content page number becomes “0” (S156: YES). In such a case, 1 is stored in the rewrite start paper page number storage area 337 (S159), the rewrite page number is set to “1” and stored in the rewrite page number storage area 338 (S160), A value linked to the screen data indicating the content head is set to the displayed content page number to be displayed on the first paper of the current page order table (S161). Then, the display start content page number is set to 0 (S162), and the process returns to the master paper main process.

  If the display start content page number is “1” or more (S156: NO), the page number (rewrite start page number) of the electronic paper 5 that needs to be rewritten is set to 1 (S157). Here, since the paper at the rear end is turned and moved to the first page, it is necessary to rewrite the display on the first page, so that it is set to “1” (see FIG. 17).

  Since the number of electronic papers 5 to be rewritten this time is only the first electronic paper 5, the number of rewritten pages is set to “1” and stored in the rewritten page number storage area 338 (S158), and the master paper main process Return to.

  On the other hand, if the paper page number of the scanned paper number is not 1 (S152: NO), since the trailing edge page is not turned and does not go to the top, it is not necessary to rewrite the display. 0 is set (S153), and the process returns to the master paper main process.

  Returning to FIG. 7, the description of the master paper main process is continued. Since it has been determined in the above-described rear end page position scanning process (S150) whether there has been a page turn of the rear end page, it is next determined whether there has been a page turn of the rear end page (S170). Specifically, whether or not there is a page turn can be determined by whether or not “1” is stored in the value of the rewritten page number storage area 338 as a result of the first page position scanning process. If there is a page turn (S170: YES), it is displayed on each electronic paper according to the page order table updated in S150, the display start content page number, the rewrite start paper page number, and the rewrite page number (see FIG. 17). Data is displayed (S200, FIG. 11).

  If there is no page turning of the trailing edge page (S170: NO), then a multi-page position scanning process for determining whether or not a plurality of pages are turned at once is executed (S180).

  Here, the multi-page position scanning process will be described with reference to FIG. As shown in FIG. 18, in the multiple page position scanning process, first, the manufacturing number of the electronic paper 5 at the rear end of the old page order table stored in the display processing work area 335 is added to the scanning paper number to be scanned. Is set (S181).

  Next, it is determined whether the page number in the old page order table of the scan paper number set in S181 is equal to the page number in the current page order table (S182). If the old page number and the new page number are equal (S182: YES), page turning is not performed, so the number of rewritten pages is set to “0” as it is (S183), and the process returns to the master paper main process.

  On the other hand, in the first page position scanning process (S120, FIG. 13) and the rear end page position scanning process (S150, FIG. 15), the processing is completed when only the first page or the rear end page is turned. Therefore, here, when the old page number and the new page number are not equal (S182: YES), it is only when a plurality of pages are beaten at a time. In this case, the value of the displayed content page number 3323 is set as the displayed content page number at the top of the current page order table (S184), and the second and subsequent displayed content page numbers in the page order table match the top page. (S185). Then, the rewriting start paper page number is set to 2, and the number of rewritten pages is set to a value obtained by subtracting 1 from the number of connected papers (S187). Through the above processing, all the pages after the second page are rewritten and an appropriate display is obtained. Then, the process returns to the master paper main process.

  Returning to FIG. 7, the description of the master paper main process is continued. Since it has been determined in the above-described multi-page position detection process (S180) whether or not there has been a multi-page page turn, it is next determined whether or not there has been a multi-page page turn (S190). Specifically, whether or not there is a page turn can be determined by whether or not a value other than “0” is stored in the value of the rewritten page number storage area 338 as a result of the multiple page position detection process. If there is a page turn (S190: YES), display data is displayed on each electronic paper according to the page order table, display start content page number, rewrite start paper page number, and rewrite page number updated in S180. (S200, FIG. 11).

  As a result of the above processing, since the binding member has been opened and closed and the display content has been rewritten at the time of page turning, the processing returns to S70 and is repeated.

  Next, a slave paper main process executed by the slave paper 4 will be described with reference to FIG. FIG. 19 is a flowchart of the slave paper main process. First, the output value of the position detection unit 47 is acquired, its own connection position is updated, and stored in the connection position storage area 431 (S301). Next, a command reception from the master paper 3 is awaited (S302).

  Then, it is determined whether or not the destination position included in the received command is its own connection position (position stored in the connection position storage area 431). If the destination position is a connection position (S303: YES), it is determined whether or not the received command is an inquiry for a manufacturing number (S304). If it is a serial number inquiry command (REQID) (S304: YES), the serial number of the slave paper 4 stored in the EEPROM 44 is returned to the master paper 3 (S305). In this embodiment, this response transmission is (M, *, *, SENDID, serial number). If it is not a serial number inquiry command (S304: NO), the process directly returns to S301.

  If the destination position is not a connection position (S303: NO), it is next determined whether or not the destination manufacturing number is its own manufacturing number (S306). If the destination manufacturing number is not its own manufacturing number (S306: NO), the process directly returns to S301.

  If the destination manufacturing number is its own manufacturing number (S306: YES), it is determined whether or not the received command is an instruction to write a display image (S307). If it is a write instruction command (REQWRITE) (S307: YES), the display data received together with the command is written in the page data expansion area 433 (S308), and then the expanded display data is displayed on the display unit 46. (S309), the master paper 3 is responded to the effect that the display is completed (S310). In this embodiment, this response transmission is (M, *, *, SENDDONE, NULL). Then, the process returns to S301.

  If it is not a write instruction command (REQWRITE) (S307: NO), it is next determined whether or not the received command is an inquiry of position information (S311). If it is a position information inquiry command (REQPOS) (S311: YES), the position information stored in the connection position storage area 431 is extracted and responded to the master paper 3 (S312). In this embodiment, this response transmission is (M, *, *, SENDPOS, connection position). If it is not a position information inquiry command (REQPOS) (S311: NO), the process directly returns to S301.

  As described above, the slave paper 4 waits for reception of a command from the master paper 3 while updating the connection position, updates the display content on the display unit 46 according to the received command, and transmits information to the master paper 3. To do.

  As described above, according to the display device 1 of the present embodiment, the slave paper 4 is bound to the ring-shaped binding member 2, and a voltage is applied to the position detection ring 24, so that each slave paper 4 The voltage value flowing through the position detection ring 24 is measured. The position information is obtained by converting the voltage value, and the master paper 3 collects the position information and rearranges the papers in the order of the positions, thereby grasping the current order of the papers and selecting the appropriate page of the content. Can be displayed. By using the position information in this way, even when page turning is performed, or when the slave paper 4 is added or removed, if the paper information is updated each time, the display contents in accordance with the current paper arrangement order Can be rewritten. Further, since the binding member 2 is formed in a ring shape and each slave paper 4 has a position detection unit, the slave paper 4 can be appropriately added to and removed from a desired position.

  Although the binding member 2 has been described as having a ring shape according to the above-described embodiment, it may have any shape as long as it has a through portion that penetrates the through hole of the electronic paper. For example, the electronic paper may be bound by a binding member having a bar-shaped through portion.

  In the above-described embodiment, it has been described that only one content is stored in the memory card 38. However, when a plurality of contents are stored in the memory card 38, the content is selected before S10. Processing is performed to display the selected content. Various methods are conceivable for the process of selecting content. For example, an operation button may be provided on the master paper, the contents stored in the memory card 38 may be displayed as thumbnails, and the user may select with the operation button.

  Further, in the data transmission, an example is given in which communication is performed using the manufacturing number as an identifier such as (S, *, S00234, REQWRITE, [display data]), but (S, 127, *, REQWRITE, [display Communication can also be performed using the position in the ring as shown in FIG. With such a communication method, the same processing can be executed without collecting slave paper identifiers.

  In the present embodiment, S20, S80, S110 in FIG. 7 and the CPU 31 of the master paper 3 that executes the paper information collection processing in FIG. 8 correspond to the position information acquisition unit and the identification information acquisition unit of the present invention.
