Indian Patents. 242087:"A DISPLAY DEVICE OF BRAILLE POINTS"
"A DISPLAY DEVICE OF BRAILLE POINTS"
The present invention relates to a display device of braille points. In the device, a coating layer 140 is formed on the upper surface of a receiving holes 120, a recognition stick 130 is installed in the hole 120 and has a metal plate 130 , a guide axis 150 is installed below a base part 100 , a header part 180 which has a supporting part 170 having a number of pins 160 therein is installed on the guide axis 50 , and a magnetic body 90 is attached to a side of the supporting part 170.Figure 3 is the representative figure.
As the braille stick 20 is installed in the hole 12 to move upward and
downward, the electromagnet 30 having coils is installed in the upper end of the hole 20 and connected to the power supply 50, the cover 40 is fixed on the upper surface of the base body 10, and the stick 20 can be pulled up or down by using the electromagnetic force from the electromagnet 30 to represent various information as a raised letters, it is possible to provide information to a blind person by using a computer.
In order to achieve the above objects, the present invention is constructed such that a display device of braille points in which a number of receiving holes are formed on the upper surface of a base part with a regular interval, a number of recognition sticks for the display device are installed respectively in the holes to be moved upwardly and downwardly, said stick being selectively protruded in the hole
of the base part, comprising:
A coating layer 140 is formed on the upper surface having the receiving holes 120 therein by means of an adhesive K between the upper surface and the
layer, and a metal plate 131 is mounted on the lower end of the stick 130 which is moved in the hole 120 upward and downward.
As shown in Fig. 3 - Fig. 5, in a display device 100 in which a number of receiving holes 120 are formed on the upper surface of the base part 110 and a number of recognition sticks 130 are installed respectively in the holes 120 to be moved upwardly and downwardly, when the stick 130 is protruded to the upper surface to make a raised letters, the header 180 is moved right and left along the
guide axis 150 installed below the base part 110 to raise the stick 130 selectively. Thus, the raised letters is formed by the stick 130 which is raised to the upper surface of the base part 110.
That is, as the metal plate 131 is mounted on the lower end of the stick 130 which can be moved in the hole 120 upwardly and downwardly, the electronic pin 160 of the header 180 forms the raised letters while the magnetic body 190 on the side of the supporting part 170 pulls down the stick 130 profruded before for forming the raised letters.
As the recess 200 is formed on the inner surface of the receiving hole 120 in
the base part 110, when the stick 130 is moved down by the metal plate and the magnetic body 190, the rubber ring 132 formed on the stick 130 is entered and fixed in the recess 220. Therefore, the stick 130 can be not moved down anymore. In the recess 200, as the upper part of the recess is curved slightly and the lower part of the recess is curved rapidly, the ring 132 can easily enters or leaves the recess from or to the upper direction and can not proceeds beyond the lower part.
Therefore, when playing the cassette player or CD player, the cassette
player and the CD player read out a column or two columns of data from the digital braille data recorded on the tape or CD per every frame pulse and determine the inherent frequency. Next, information for existence and nonexistence of the inherent frequency about each point number is latched as next frame pulse signal input. Then, by driving a pertinent pin 160 in the header 180 by using the latched data, the stick 130 installed in the hole 120 is protruded to form six-point type braille.
While the present invention has been described and illustrated herein with reference to the preferred embodiments thereof, it will be apparent to those skilled in the art that various modifications and variations can be made therein without departing from the spirit and scope of the invention. Thus, it is intended that the present invention covers the modifications and variations of this invention that
come within the scope of the appended daims and their equivalents,
1. A display device of braille points comprising:
a base part 100 in which a number of receiving holes 120 are formed in upper part and a coating layer 140 is formed on upper surface;
a number of recognition sticks 130 installed respectively in the holes 120 to be moved upwardly and downwardly and having a metal plate 131 attached to the lower end of the stick;
a guide axis 150 is installed below the base part 100 having the holes 120 to move the stick upwardly and downwardly;
a header part 180 installed on the guide axis 150 to be moved right and left and having a supporting part 170, said supporting part 170 having a number of electronic pins 160 selectively protruded by an electric signal therein and a magnetic body 190 attached to a side thereof;
a recess 200 formed on the inner surface of the receiving hole 120 of the base part 110; and
a ring 132 made of rubber is formed on the circumference of the stick 130 to engage with said recess 200 to prevent the stick 130 from being pulled down entirely by magnetic body 190;
wherein, an upper part of the recess 200 is curved slightly, the lower part of the recess is curved rapidly and the ring 132 easily enters or leaves the recess from or to the upper direction.
2.	The display device of braille points as claimed in claim 1, wherein the supporting part 170 installed on the header part 180 and having the electronic pin 160 protruded by the electric signal is made of non-magnetic material.
3.	The display device of braille points as claimed in claim 1, wherein an inherent frequency is assigned to each of 3 point numbers of one column of braille which is comprised of six points formed on the upper surface of the base part 110 by using the receiving hole 120 and the stick 130, a frequency signal corresponding to each of the point numbers is continuously recorded as a frame on a cassette tape, each time a column data is completed a frame pulse is recorded on a track of the tape, and a pertinent pin 160 in the header 180 is driven in case of playing the cassette.
