JPH025081A - Braille display - Google Patents

Abstract

PURPOSE:To sense an indication by a computer hot visually, but by the sense of touch by forming a recessed and projection pattern of pins in a frame surface. CONSTITUTION:Pins 2 are thick enough to project from and enter many through holes provided in one surface of a box-shaped frame 1 in a matrix. Then a signal from an external computer, etc., is converted into a braille pattern by a control part 4 which receives the signal through a control cable 6 and a driving part 3 which moves the pins 2 individually is controlled to form a recessed and projection pattern of pins 2 on the surface of the frame 1 in conformity with the braille pattern. Consequently, information of a character, etc., can be sensed by the sense of a hand, etc., and even a person whose is handicapped in seeing can use the display of the computer, etc., without depending upon the sight.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display for expressing information from a computer or the like.

[Prior Art] Conventionally, this type of display has expressed information by scanning electron beams, like a television screen.

[Problems to be Solved by the Invention] The above-mentioned conventional display has the disadvantage that a person who is visually impaired cannot use a computer, etc. that has a display because a person must sense information only visually. There is.

[Means for Solving the Problems] The Braille display of the present invention has a box-shaped frame in which a large number of through holes are arranged in a matrix on one side, and a Braille display provided for each through hole in the frame. , a pin that is thick enough to go in and out of each through hole, a drive unit that individually moves each pin in the axial direction of the through hole so that its tip protrudes or retracts from the frame surface, and a signal cable from a computer, etc. A connecting connector to be connected; a control cable that receives a signal from the computer, etc. through the connecting connector; and a control cable that converts the signal input from the computer, etc., input through the control cable into a Braille pattern, and converts the signal from the computer, etc., into a Braille pattern; and a control section that controls the drive section so that the pattern of concavities and convexities formed by the pins on the surface of the frame match.

[Operation] The control unit converts signals input from a computer, etc. into a Braille pattern, controls the drive unit to match this pattern, and opens a large number of through holes arranged in a matrix on one side of the frame. A pin of a certain thickness that can be inserted and removed for each hole is made to protrude or retract from the frame surface in the axial direction of the hole to form an uneven pattern on the frame surface, so people do not have to rely on their visual sense. It is possible to detect information that is not displayed on computers, etc. by using the sense of touch.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of one embodiment of the Braille display of the present invention, FIG. 2 is a longitudinal sectional view of the Braille display of FIG. 1, and FIG.
The figure is a diagram of a Braille pattern used in the Braille display of FIG. 1.

This braille display consists of frame 1, pin 2 and drive unit 3.
, a control section 4 , a connecting connector 5 , and a control cable 6 . The frame 1 is box-shaped and has a large number of through holes arranged in a matrix on its upper surface. The pin 2 is formed to have a thickness that allows it to go in and out of each through hole on the two sides of the frame 1. The drive unit 3 individually moves the pins 2 up and down within the through holes so that their tips protrude or retract from the surface of the frame 1. The control unit 4 receives a signal from an external computer (not shown) via a control cable 6 connected to a connector 5, converts it into a Braille pattern, an example of which is shown in FIG. The driving unit 3 is controlled so that the pattern of the unevenness formed by the pins 2 on the surface of the frame 1 matches the pattern. The Braille pattern is formed by a combination of 6 characters in 3 rows and 2 columns, so to represent "A", "B", and "C", for example, use the pattern shown in Figure 3 to create a double circle (◎). ), the information content (in this case characters) are expressed.

[Effects of the Invention] As explained above, the present invention has a large number of through-holes provided in a matrix on one side of a box-shaped frame, each of which has pins thick enough to be able to go in and out of each hole, so that an external computer, etc. A control unit receives a signal from the frame via a control cable, converts it into a Braille pattern, controls a drive unit that moves the pins individually, and converts the pattern formed by the unevenness of the pins on the surface of the frame into the Braille pattern. By using a Braille display configured to match the pattern of the Braille display, information such as letters can be recognized by the tactile sense of the hands, so even visually impaired people can use displays such as computers without relying on sight. There is an effect that it can be done.
