At step SP31, the CPU 20 of the electronic book 2 transfers the electronic book server 3 to the kiosk terminal 5.
The book data written via the is displayed to allow the user to read the book, and the process proceeds to the next step SP32.

In step SP32, when the CPU 20 of the electronic book 2 reads the book data acquired via the kiosk terminal 5 and leaves the remaining several pages in the unread state, the CPU 20 of the electronic book 2 indicates the number of pages read at the present time. The data is sent to the electronic book server 3 as usage data, and the process proceeds to the next step SP33.

In step SP33, the CPU 30 of the electronic book server 3 updates the usage history correspondence table 39 based on the usage status data, and acquires the download right acquisition procedure of book data of the indirect method by the electronic book 2 and the display processing of the book data. Finish the procedure.

(3) Book Data Display Processing Next, the reading mode when the user actually reads the book data downloaded to the electronic book 2 will be described.

(3-1) Page Display Processing in Reading Mode The CPU 20 of the electronic book 2 displays the “My bookshelf” screen 60 (FIG. 15) downloaded from the electronic book server 3 in the reading mode, and the user selects it. “Title”, “Author”, corresponding to the selected book 61,
For the book 61 via the blowing unit 62 including attribute information such as “last read date”, “purchase date”, “page number” and “other information (page number already read etc.)” Show summary.

When the book 61 is selected and determined, the CPU 20 of the electronic book 2 downloads and displays the reading determination screen 130 for the book 61 as shown in FIG. 25 from the electronic book server 3.

On the reading determination screen 130, the cover portion of the book 61 is displayed on the right side display section 11, and the blowing section 62 containing the attribute information about the book 61 is displayed on the left side display section 10 in "My bookshelf". The screen 60 is displayed in the same manner.

After confirming the reading decision screen 130, the user decides whether or not to read, clicks the "Read" button 133 when reading, and clicks the "Cancel" button 134 when not reading. click.

When the CPU 20 of the electronic book 2 recognizes that the “Read” button 133 has been clicked on the reading decision screen 130, the CPU 6 of the electronic book server 3 reads the book 6 concerned.
A download request for 1 is made.

Thus, the CPU 3 of the electronic book server 3
0 acquires the reading progress status information of the book 61 from the usage history correspondence table 39 of the usage history database 34B, and transmits the reading progress status information and the unread portion of the book data for 10 pages to the electronic book 2. Has been done.

In this case, as shown in FIG. 26, the CPU 20 of the electronic book 2 causes the first two pages (for example, 15/3) of the 10 pages downloaded from the electronic book server 3.
50 pages and 16/350 pages) are displayed on the right side display unit 11 and the left side display unit 10, respectively.

At this time, at the same time, the CPU 20 of the electronic book 2
Recognizes which position the currently displayed page corresponds to the total number of pages of the entire book according to the reading progress status information, and as the recognition result, 15/350 pages of the right side display unit 11 and 16/350 of the left display 10
Vertical stripe patterns 136 and 137 having the same thickness as that of an actual book are displayed on the outer edge of the page.

The CPU 20 of the electronic book 2 performs fractional display such as "15/350" or "16/350" as the number of pages on the 15/350 page and the 16/350 page. Not only the page number but also the total number of pages of the whole book is accurately presented numerically.

That is, the CPU 20 of the electronic book 2 displays the pages 15/350 of the right side display unit 11 and the left side display unit 10.
By displaying vertical striped patterns 136 and 137 having the same thickness as an actual book on the outer edge of 16/350 pages of the above, the user can determine which position of the entire page the currently displayed page corresponds to. On the other hand, it can be intuitively and roughly recognized, and by displaying fractions such as “15/350” and “16/350” in one corner of the 15/350 and 16/350 pages,
It is possible to make it possible to accurately numerically recognize which position the currently displayed page corresponds to in the entire book.

By the way, the CPU 20 of the electronic book 2 indicates "0" as to which position in the whole book the page to be displayed at present corresponds to in accordance with the reading progress status information.
"0.1", "0.2", "0.3", ... "0.
The thickness of the vertical stripe patterns 136 and 137 is finely changed for each of the 11 stages by recognizing it in 9 stages of "9" and "1.0".

In the present embodiment, recognition is performed in 11 steps, but the present invention is not limited to this, and the difference in the total number of pages and the liquid crystal display in the left side display section 10 and the right side display section 11 are not limited thereto. The thickness of the vertical stripe patterns 136 and 137 may be finely changed according to the display capability.

Therefore, when the CPU 20 of the electronic book 2 recognizes that the reading progress status information is "0", it recognizes that no reading has been done up to now and no page has been displayed yet. The vertical stripe pattern 136 is not displayed at all, and only the left vertical stripe pattern 137 is displayed thickest.

Similarly, when the CPU 20 of the electronic book 2 recognizes that the reading progress status information is "0.5",
Vertical striped pattern 136, recognizing that it has progressed to about half
And 137 are displayed with the same thickness.

As described above, the CPU 20 of the electronic book 2 is
The reading progress information is recognized in 11 steps and
By adjusting the thickness of the vertical stripe patterns 136 and 137 by the fineness of each step, the actual reading progress and the vertical stripe pattern 13
6 and the thickness of 137 are prevented from being uncomfortable.

By the way, the CPU 20 of the electronic book 2 operates as shown in FIG.
As shown in FIG. 6, the page displayed on the right side display unit 11 is the front side of the book, and the page displayed on the left side display unit 10 is the back side of the book. As the reading progress progresses, vertical stripes 13
The overlapping degree of pages in 6 is gradually thickened, and the overlapping degree of pages in the vertical stripe pattern 137 is gradually thinned.

Further, the CPU 20 of the electronic book 2 can determine whether it is the vertical writing display or the horizontal writing display based on the attribute information of the book, and when it judges that it is the horizontal writing display. Contrary to the case of vertical writing, the page displayed on the left side display unit 10 is the front side of the book and the page displayed on the right side display unit 11 is the back side of the book, and vertical stripes are formed as the reading progress progresses. The degree of page overlap in 137 is gradually thickened, and the page overlap in the vertical stripe pattern 136 is gradually thinned.

The CPU 20 of the electronic book 2 actually sets the vertical stripe line to the number of remaining pages according to the number of remaining pages when the overlapping state of the pages in the vertical striped pattern 136 and the vertical striped pattern 137 becomes thin to some extent. It is designed to match.

In this case, the vertical stripe patterns 136 and 137.
The number of lines of vertical stripes that can be displayed depends on the display capability of the liquid crystal display in the left display unit 10 and the right display unit 11. For example, when the number of remaining pages is 5 or less, vertical stripes corresponding to the number of remaining pages are displayed. The line is displayed so as to actually match the remaining number of pages.

As a result, the user can recognize the actual number of remaining pages to some extent accurately by the vertical striped line indicating the degree of page overlap in the vertical striped pattern 136 and the vertical striped pattern 137, and whether the user actually reads the book or not. You can feel like it.

(3-2) Page display processing procedure according to reading progress, that is, as shown in FIG. 27, CPU 2 of electronic book 2
In the case of 0, the routine starts from the start step of RT1 and moves to step SP41.

At step SP41, the CPU 20 of the electronic book 2 recognizes the book 61 selected by the user via the "My bookshelf" screen 60 (FIG. 15) and displays the reading decision screen 130 (FIG. 25) concerning the book 61. It is downloaded from the electronic book server 3 and displayed, and then the process proceeds to the next step SP42.

In step SP 42, the CPU 20 of the electronic book 2 reads the book 6 via the reading decision screen 130.
Determine if it was decided to read 1. If a negative result is obtained here, this means that the user has no intention to read the book 61 by clicking the “Stop” button 134, and at this time, the CPU 20 of the electronic book 2 reads “My bookshelf”. Returning to the screen 60, the user is allowed to select another book.

On the other hand, when a positive result is obtained in step SP42, this means that the user has the intention to read the book 61 by clicking the "read" button 133, and at this time, the electronic book. 2 CPU 20
Moves to the next step SP43.

In step SP43, the CPU 20 of the electronic book 2 acquires 11-step reading progress status information regarding the book 61 from the usage history database 34B of the electronic book server 3, and at the same time, the book data storage section 34A.
From, the book data of the book 61 is downloaded and acquired, and the routine goes to the subsequent Step SP44.

In step SP44, when displaying the downloaded book data, the CPU 20 of the electronic book 2 recognizes, based on the reading progress information, what stage of the entire page the read part corresponds to, and at that stage. The vertical striped pattern 136 and the vertical striped pattern 137 having the corresponding thickness are displayed on the outer edge of the page, and the process proceeds to the next step SP45.

In step SP45, the CPU 20 of the electronic book 2 determines whether or not the user inputs a command to end the reading mode. When a negative result is obtained, the CPU 20 of the electronic book 2 proceeds to next step SP46.

In step SP46, the CPU 20 of the electronic book 2 determines whether a page turning operation has been performed via the jog dial 12A or the like. If a negative result is obtained here, the CPU 20 of the electronic book 2 goes to step SP.
Returning to 44, the vertical stripe pattern 136 and the vertical stripe pattern 137 are continuously displayed.

On the other hand, if a positive result is obtained in step SP46, the CPU 20 of the electronic book 2 moves to next step SP47, performs page turning operation for the number of pages corresponding to the page turning operation, and then executes step SP44. The process returns to step SP44 and the subsequent steps are repeated.

By the way, the CPU 20 of the electronic book 2 recognizes that the reading mode is ended when a positive result is obtained in step SP45, and the next step SP4
Go to 8.

In step SP48, the CPU 20 of the electronic book 2 uses the number of pages for the two facing pages read at the current point of time as the usage status data.
Then, the usage history database 34B is updated and the page display processing procedure according to the reading progress status is ended in the next step SP49.

(3-3) Progress status sensation notification processing according to reading progress status Further, the CPU 20 of the electronic book 2 weights, for example, inside the right display section 11 as shown in FIGS. 28 (A) and 28 (B). A moving unit 150 is provided, and the CPU 20 can move and control the position of the center of gravity of the right display unit 11.

In the weight moving section 150, a battery bracket 151 having the battery 28 mounted thereon is fixed to a rack 153, the rack 153 is engaged with the pinion gear 154, and the pinion gear 154 is combined with the worm gear 155. ing.

Further, the weight moving section 150 is adapted to rotationally drive the worm gear 155 by a stepping motor 156 driven under the control of the CPU 20, and the rack force is transmitted by the rotational force transmitted from the worm gear 155 to the pinion gear 154. 153 can be moved in parallel between the rotating shaft portion 12 side of the right side display portion 11 and the open end portion side.

As a result, the weight moving section 150 is moved to the rack 1
The battery 28 is also moved in parallel with the parallel movement of 53, so that the center of gravity of the right side display unit 11 can be moved.

In practice, as shown in FIG. 29, the electronic book 2
The CPU 20 enters from the start step of routine RT2 and moves to step SP51. In step SP51, the CPU 20 of the electronic book 2 displays the "My bookshelf" screen 60.
When the book 61 selected by the user is recognized through (FIG. 15) and the reading determination screen 130 corresponding to the book 61 is requested to the electronic book server 3, the next step SP5.
Move to 2.

In step SP52, the CPU 20 of the electronic book 2 reads the book 61 via the reading determination screen 130 (FIG. 25) downloaded from the electronic book server 3.
Determine whether to read the.

If a negative result is obtained here, it means that the "stop" button 134 is clicked and the user has no intention to read the book 61. At this time, the CPU 20 of the electronic book 2 returns to step SP51. Let the user select the book again.

On the other hand, when a positive result is obtained in step SP52, this means that the user has the intention to read the book 61 by clicking the "read" button 133, and at this time, the electronic book 2 The CPU 20 moves to the next step SP53.

In step SP53, the CPU 20 of the electronic book 2 obtains 11-step reading progress status information regarding the book 61 from the usage history database 34B of the electronic book server 3 and at the same time, the book data storage section 34A.
To download and obtain the book data, and move to the next step SP54.

In step SP54, the CPU 20 of the electronic book 2 has a weight position correspondence table (not shown) indicating the position of the battery 28 in the right side display portion 11 in accordance with the 11-step reading progress status information. , The position of the battery 28 corresponding to the stage of the reading progress status information is detected based on the weight position correspondence table, and the next step S
Move to P55.

In step SP55, the CPU 20 of the electronic book 2 detects the current position of the battery 28 in the right side display section 11 and the right side display section of the battery 28 detected from the weight position correspondence table based on the reading progress status information in step SP54. The difference from the position within 11 is calculated and grasped, and the routine goes to the subsequent Step SP56.

At step SP56, the CPU 20 of the electronic book 2 gives the stepping motor 156 a drive command for moving only the difference calculated at step SP55 to move the battery 28 in parallel, and proceeds to the next step SP57.

In this case, the CPU 20 of the electronic book 2
When the stage based on the reading progress status information is close to the “0” stage and the progress of reading is shallow, the battery 28 is rotated.
Outputs a drive command to position it near the 2 side,
When the stage based on the reading progress status information is close to the “1” stage and the progress of reading is deep, the battery 28 is connected to the right side display unit 1.
A drive command for locating the position 1 on the open end side is output.

In step SP57, the CPU 20 of the electronic book 2 determines whether or not the page turning operation is performed by the user. If a positive result is obtained here, the CPU 20 of the electronic book 2 actually performs the page turning operation, returns to step SP54, and repeats the above-described processing.

That is, the CPU 20 of the electronic book 2 performs the page turning operation, grasps the reading progress status information,
When it is recognized that the reading progress status information has changed due to the page turning operation, the battery 28 is moved in parallel again according to the change.

On the other hand, if a negative result is obtained in step SP57, this means that the page turning operation has not been performed by the user, and it is not necessary to continue displaying the current page and move the position of the battery 28. At this time, the CPU 20 of the electronic book 2 moves to the next step SP58 and ends the center-of-gravity movement control processing procedure.

Therefore, the CPU 20 of the electronic book 2 positions the battery 28 at a position closest to the rotary shaft portion 12 when the reading progress is still shallow and almost no pages are being read, and the reading progress is deep. When the user is reading to a page where reading is likely to end, the battery 28 is positioned at a position closest to the open end side of the right side display unit 11 so that the progress of the page can be adjusted according to the progress of the page. As a result, the impression that the weight of the right side display unit 11 changes like a real book can be felt very naturally.

Therefore, the user unconsciously recognizes that the body weight of the electronic book 2 changes naturally with the reading progress, and the reading progress is not visually confirmed by the vertical stripe patterns 136 and 137. Can be intuitively grasped.

In the electronic book 2, the weight controller 150
However, the present invention is not limited to this, and may be incorporated in the left side display unit 10 or may be incorporated in both the left side display unit 10 and the right side display unit 11. You can

(4) Operations and Effects With the above configuration, the CPU 30 of the electronic book server 3
In the purchase mode, the download right of the book data is given based on the download right acquisition request from the electronic book 2, and the book data ID code of the book data given the download right and the user ID code of the electronic book 2 are given. In association with the book purchaser correspondence table 38 (see FIG.

At this time, the CP of the electronic book server 3
The U30 associates the user ID code with the attribute information such as the book data ID code, the reading flag, and the reading progress status information by using the usage history correspondence table 3
9 (FIG. 14) is generated and the usage history correspondence table 39 is generated.
Various usage histories related to the user's book data are managed via.

On the other hand, when the CPU 20 of the electronic book 2 acquires the download right for downloading the book data via the electronic book server 3, the CPU 20 of the electronic book server 3 notifies the book data ID code to the acquired book data. From then on, when downloading the book data thereafter, it is only necessary to transmit the book data ID code to the electronic book server 3.

When the book data download request is received from the electronic book 2, the CPU 30 of the electronic book server 3 confirms the usage status based on the usage history correspondence table 39 (FIG. 14) and confirms the usage of 10 pages after the unread portion. The book data is transmitted to the electronic book 2.

Thus, the CPU 20 of the electronic book 2
When a request for downloading the book data is made, the book data for 10 pages of the unread portion can be automatically acquired from the electronic book server 3, and if the download is requested again when the reading of the 10 pages is completed, further The book data for 10 pages can be downloaded from the unread part of.

Therefore, even if the data capacity of the RAM 21 is not large, the electronic book 2 acquires only the required number of pages after the unread portion from the electronic book server 3 based on the download right at any time, anywhere and any number of times. Can be displayed.
