The braille is read by causing the user to touch the braille pin 21 with the finger.

The communication interface 9 of the electronic braille display device 100 does not necessarily have to be connected to the electronic book data device 50 by wire. For example, the communication interface 9 is electronically connected by wireless communication means such as Wi-Fi (registered trademark) or Bluetooth (registered trademark). You may connect to the book data apparatus 50. FIG. By configuring the electronic braille book system as described above in the electronic book data device 50 and the electronic braille display device 100, the size of the electronic braille display device 100 can be reduced.

(Actuator (braille pin driver) 22)
As the actuator (braille pin drive unit) 22, various actuators such as an electromagnetic actuator that raises and lowers the braille pin 21, a laminated piezoelectric actuator, and a bimorph piezoelectric actuator that warps a film in which the braille pin 21 is installed at one end are used. However, electromagnetic actuators tend to be large in size, and multilayer piezoelectric actuators have a small amount of displacement when voltage is applied. Therefore, it is possible to reduce the size and thickness of the actuator, and use a bimorph piezoelectric actuator that can obtain a large amount of displacement. Is desirable.

  Other than the above, it is also possible to use a film type actuator that warps a film in which braille pins 21 are installed at one end. For example, by using a film-type actuator such as an ion conductive actuator or a conductive polymer actuator, it is more desirable because it can be made light in weight and does not require a large voltage for driving.

(Actuator control means 24)
The actuator wiring film substrate 20 is provided with a plurality of actuator driving wirings 23 for connecting the electrode terminals of the actuators 22, and each actuator driving wiring 23 is connected to the actuator control means 24.

  That is, when the actuator control means 24 applies a drive voltage to the actuator 22 via the actuator drive wiring 23 wired on the actuator wiring film substrate 20, the actuator 22 warps and pushes the braille pin 21 upward. When the drive voltage of the actuator 22 is removed, the warp of the actuator 22 disappears and the braille pin 21 is returned to the lower side.

  When the Braille pin 21 is moved upward in the Braille pin through hole 11 by the actuator 22, the Braille pin 21 protrudes from the surface of the contact position detection unit 10. And the braille display part 5 which displays braille by the group of the several braille pin 21 which protruded, and the group of the through-hole 11 is formed.

A surface protective layer 14 is formed on the upper layer so that the user can touch the finger.

(Capacitive touch sensor)
As shown in FIG. 3, the touch sensor wiring film substrate of the contact position detection unit 10 has a touch sensor drive electrode pattern 12 and a touch sensor detection electrode pattern 13 formed on a film substrate 10a such as a resin substrate, and the patterns are orthogonal to each other. In this manner, a capacitive touch sensor unit using the capacitive element C formed as shown in FIG. 2 at the intersection of the electrodes is configured.

  One end of the touch sensor drive electrode pattern 12 connected to one end of the capacitive element C is connected to the AC signal source of the transmission circuit 32, and the touch sensor detection electrode pattern 13 connected to the other end of the capacitive element C is received by the receiving circuit. Connect to 33 voltage detectors. And the presence or absence of a finger touch is detected by measuring the capacitance change of the capacitive element C.

  In addition to the above-described configuration, the contact position detection unit 10 includes a touch sensor drive electrode pattern 12 and a touch sensor detection electrode pattern 13 that are orthogonal to each other on one side of the film substrate 10a, and touches the touch sensor drive electrode pattern 12. By forming an insulating film at a portion where the sensor detection electrode patterns 13 intersect, it is possible to adopt a configuration in which a capacitive touch sensor unit is disposed only on one surface of the film substrate 10a.

(Touch sensor control means 30)
As shown in FIG. 3, the touch sensor control unit 30 includes a contact position detection circuit 31, a reception circuit 33, and a transmission circuit 32. The touch sensor drive electrode pattern 12 is connected to the transmission circuit 32 of the touch sensor control means 30, and the touch sensor detection electrode pattern 13 is connected to the reception circuit 33. When the user's finger touches the contact position detection unit 10, the contact position detection circuit 31 of the touch sensor control means 30 controls the transmission circuit 32 and the reception circuit 33 to control the user's finger to the contact position detection unit 10. Detect the contact position. The contact position detection circuit 31 outputs the detected finger contact position data 30 a to the display control means 40.

(Display control means 40)
As shown in FIG. 4, the display control means 40 includes a contact position analysis means 41, a Braille display switching timing command means 42, a book data storage means 43, a book data reading means 44, a Braille translation means 45, and a Braille display control. Part 46.

(Braille display procedure)
With reference to FIG. 4, the Braille display procedure in the first embodiment will be described.
(Step S1)
The contact position analysis means 41 receives from the touch sensor control means 30 the contact position data 30a indicating the position of the user's finger that has touched the contact position detection unit 10 of the Braille substrate 1.

Upon receiving the contact position data 30 a, the contact position analysis unit 41 creates finger contact data 41 a indicating that the finger has touched the Braille display unit 5 and outputs it to the Braille display switching timing command unit 42. Further, the contact position analysis means 41 analyzes the outline of the range in which the user's finger is in contact based on the contact position data 30a. There is a change in the contact position data 30a sent continuously, and the finger position offset data 41b indicating whether the outline of the range where the finger contacts the Braille display unit 5 is shifted to the left or right of the Braille display unit 5, It outputs to the braille display switching timing command means 42.

(Step S2)
When the Braille display switching timing command means 42 receives the finger contact data 41a and the finger position offset data 41b, the Braille display switching timing command means 42 creates display switching timing data 42a that specifies the timing for switching the display of the displayed Braille. The created display switching timing data 42 a is output to the book data reading means 44.

(Step S3)
The communication interface 9 reads the electronic book data 50 a of several characters around the portion corresponding to the character whose braille is being read from the electronic book data device 50 for healthy persons, and stores it in the book data storage unit 43. The number of characters that are necessary for the characters to be stored to be displayed without any delay in switching the display of Braille can be stored.

(Step S4)
The book data reading unit 44 receives the display switching timing data 42a from the Braille display switching timing command unit 42, and displays the Braille characters at the timing specified by the display switching timing data 42a from the book data storage unit 43 to the book text data 43a. Is output to the Braille translation means 45 together with the display switching timing data 42a.

(Step S5)
When the book text data 43a is read from the book data storage unit 43, the book data storage unit 43 deletes the read characters, and the communication interface 9 corresponds to the number of characters deleted from the electronic book data device 50 for healthy persons. The electronic book data 50 a having several characters to be read is newly read out and stored in the book data storage unit 43. By doing so, it is not necessary to provide a large storage medium in the electronic braille display device 100.

(Step S6)
The Braille translation means 45 converts each character of the book text data 43a into Braille data 45a representing Braille information of the Braille pattern using the Braille translation calculation data, and outputs it to the Braille display control unit 46 together with the display switching timing data 42a. To do.

  Although the display control means may be provided in advance for the Braille translation calculation data, the communication interface 9 of the electronic Braille display device 100 communicates with an external database through a wireless communication network to acquire the Braille translation calculation data. The Braille translation means 45 can also be used.

  Alternatively, the communication interface 9 is configured to be electrically connected to a personal computer or a portable terminal device with a wired communication cable, and to acquire necessary braille translation calculation data from the personal computer or the portable terminal device. You can also

(Step S7)
The Braille display control unit 46 creates the actuator control data 46a according to the Braille data 45a and outputs it to the actuator control means 24 at the timing specified by the obtained display switching timing data 42a, so that the actuator of the Braille display unit 5 22 control is commanded.

(Step S8)
The actuator control means 24 drives the actuator 22 at a designated timing according to the actuator control data 46a obtained from the braille display control unit 46, and displays the braille by moving the braille pin 21 up and down according to the braille data 45a.

(Braille display switching timing control procedure 42)
In step S2 to step S7, the procedure for performing control for speeding up or slowing down the timing for switching the display of Braille will be described in detail. As described above, the braille display switching timing command means 42 creates the display switching timing data 42a that specifies the timing for switching the display.

(Step S1-1)
When the user's finger is not touched and moved as it is in the area for displaying the braille on the contact position detecting unit 10 of the braille board 1, the contact position analyzing means 41 creates only the finger contact data 41a and the braille display switching timing. Output to the command means 42. The timing for switching the display of Braille is set in advance in the Braille display switching timing command means 42. When the Braille display switching timing command means 42 continuously receives only the finger contact data 41a, the Braille display switching timing command means 42 Display switching timing data 42a for designating switching of Braille display according to a preset timing of switching Braille display is created.

(Step S7-1)
When the display switching timing data 42a for designating switching of the braille display according to the preset timing of switching the display of the braille is created, the braille display control unit 46 controls the actuator so as to switch the display of the braille at a constant speed. Data 46a is created. In this case, the next character is displayed at a constant speed on the braille substrate 1.

(Step S1-2)
After the user's finger comes into contact with the braille display area on the contact position detection unit 10 of the braille substrate 1, the finger that contacts the braille display unit 5 is tilted in either the left or right direction, and the user's finger touches. When the outline of the range is shifted to the left or right, in addition to the finger contact data 41a, the contact position analysis unit 41 outputs finger position offset data 41b indicating whether the finger contact range is shifted to the left or right. The output finger contact data 41a and finger position offset data 41b are received by the braille display switching timing command means 42.

(Step S1-3)
When the finger position offset data 41b is data indicating that the range in which the finger contacts the Braille display unit 5 is shifted to the right side of the Braille display unit 5, the Braille display switching timing command means 42 preliminarily switches the Braille display. The display switching timing data 42a is created by shortening the timing for switching the display of the Braille characters set in the timing command means 42.

(Step S7-3)
When the display switching timing data 42a designated so that the timing for switching the display of Braille is shortened, the Braille display control unit 46 follows the display switching timing data 42a to display the next Braille at a short timing. The control data 46a is created. In this case, on the Braille substrate 1, the timing until the next character is displayed is accelerated, and the display speed of the Braille is increased.

(Step S1-4)
When the finger position offset data 41b is data indicating that the range in which the finger contacts the Braille display unit 5 is shifted to the left side of the Braille display unit 5, the Braille display switching timing command means 42 preliminarily switches the Braille display. The timing for switching the braille display set in the timing command means 42 is lengthened, and the display switching timing data 42a is created.

(Step S7-4)
When the display switching timing data 42a is specified so that the timing for switching the display of Braille becomes longer, the Braille display control unit 46 displays the next Braille at a longer timing according to the display switching timing data 42a. The actuator control data 46a to be instructed is created. When the next Braille is displayed at a long timing, the time until the next Braille is displayed on the Braille substrate 1 becomes longer, and the display speed of the Braille becomes slower.

  Through the above procedure, the user can read the displayed braille while keeping his / her finger in contact with the braille displayed on the braille substrate 1, and can adjust the switching speed of the displayed braille.

(Modification 1)
As a first modification, when the contact position analysis unit 41 analyzes the contact position data 30a, the left and right side displacement size of the range where the finger contacts the Braille display unit 5 is analyzed, and the finger position displacement data 41b is obtained. Information indicating the size of the finger contact position can be included.

  The display switching timing command means 42 that has received the finger position deviation data 41b creates display switching timing data 42a in which the amount of change in the timing for switching the display is larger as the deviation of the finger contact position is larger. The display switching timing data 42a having a smaller amount of change in timing for switching the display can be generated as the deviation of the shift is smaller.

  By doing so, it is possible to control the degree of acceleration of the display speed of the Braille by controlling the size with which the user moves the finger to the left and right of the Braille display unit 5.

(Modification 2)
As a second modification, when the contact position analysis unit 41 analyzes the contact position data 30a, the movement speed of the finger that causes the user to move the finger in contact with the braille display unit 5 to the left and right is read and used. Data on the movement speed of the person's finger can be created as the finger position offset data 41b.

  Then, the Braille display switching timing command means 42 creates display switching timing data 42a in which the timing change amount for switching the display is controlled according to the finger position deviation data 41b indicating the moving speed of the finger.

  In this way, it is possible to control the degree of acceleration of the display speed of the Braille by controlling the speed at which the user moves the finger to the left and right of the Braille display section 5.

(Modification 3)

  On the upper surface of the Braille substrate 1 exposed in the region of the finger touch window 5a of the electronic Braille display device 100, there are at least three brailles: a braille at an intermediate position in the reading order, a braille at a preceding position, and a braille at a delayed position. Is displayed, and the user touches the upper surface of the braille substrate 1 in order to read the braille. Three or more braille characters may be displayed.

(Step S11-1)
First, the contact position analysis means 41 receives the movement position data 6 a of the Braille board 1 from the Braille board movement detection means 6.

  Next, the contact position analysis unit 41 receives from the touch sensor control unit 30 the contact position data 30a of the user's finger to the contact position detection unit 10 of the Braille board 1.

  The contact position analysis means 41 calculates the time change of the movement position data 6a of the Braille board 1 and the contact position data 30a of the user's finger to the Braille board 1 so that the position of the finger reading the Braille is an intermediate position. It is determined whether it is ahead of or behind the Braille reading direction B.

  When the position of the finger on which the user reads the braille on the braille substrate 1 precedes the braille reading direction B from the intermediate position, the braille contact position analyzing means 41 determines that the reading speed of the braille by the user is braille. It is determined that the moving speed of the substrate 1 is faster.

(Step S18-1)
When the braille contact position analyzing means 41 determines that the reading speed of the braille by the user is faster than the moving speed of the braille board 1, the contact position analyzing means 41 instructs to accelerate the moving speed of the braille board 1. A substrate speed control command 48 a is output to the substrate movement speed designation means 48.

(Step S19-1)
The board movement speed designation means 48 that has received the board speed control command 48a controls the board movement speed control means 3 to increase the rotation speed of the motor 4, thereby increasing the movement speed of the Braille board 1 and the finger of the user. Keep up with the feed rate.

(Step S11-2)
On the other hand, when the position of the user's finger reading the Braille on the Braille substrate 1 is delayed with respect to the Braille reading direction B with respect to the intermediate position, the contact position analysis means 41 determines that the reading speed of the Braille by the user is Braille. It is determined that the moving speed of the substrate 1 is slower.

(Step S18-2)
If the contact position analysis means 41 determines that the reading speed of the Braille by the user is slower than the movement speed of the Braille board 1, the board that instructs the contact position analysis means 41 to reduce the movement speed of the Braille board 1 A speed control command 48 a is output to the substrate moving speed specifying means 48.

(Step S19-2)
The board movement speed designation means 48 that has received the board speed control command 48a controls the board movement speed control means 3 to slow down the rotation speed of the motor 4, thereby delaying the movement speed of the braille board 1 and Adjust to the feed rate.

(Step S11-3)
When the position of the finger of the user who reads the braille on the braille board 1 coincides with the intermediate position, the contact position analysis means 41 has the reading speed of the braille by the user coincides with the moving speed of the braille board 1. It is determined that

(Step S18-3)
When the contact position analyzing unit 41 determines that the reading speed of the Braille by the user matches the moving speed of the Braille substrate 1, the contact position analyzing unit 41 does not output the substrate speed control command 48a.

(Step S19-3)
Therefore, the substrate moving speed designating unit 48 does not give an instruction to accelerate or decelerate the rotation speed of the motor 4 to the substrate moving speed control unit 3. Therefore, the moving speed of the braille substrate 1 is maintained.
