Embodiment 2

[0174] FIG. 18A schematically shows a touch stick display device (Braille display device) according to an embodiment of the present invention. The touch stick display device 300 includes eight elements. The first element comprises a disc-shaped rotating part 310 having a plurality of perforations arranged in its radial position, separated from each other and present in the main plane of the rotating part (touch surface TS). The second element includes a gear 340 which meshes with the periphery of the rotating part 310 . The third element includes a rotary drive (not shown) for rotating the rotary member 310, the rotary drive including gears, motors and the like. The fourth element includes rods 301, each rod is arranged in each hole, and in the length direction of each hole or each rod between the first position (rod reset position) and the second position (rod display position) between rise and fall.

[0175] The fifth element comprises O-rings 370 mounted respectively on ...

Embodiment 3

[0197] The touch stick display device (braille display device) displayed in this embodiment is similar to the touch stick display device in Embodiment 2, except that the touch stick holding mechanism or device here is partially different from the touch stick holding mechanism in Embodiment 2 or equipment. More specifically, in this embodiment, the annular member (O-ring) in Embodiment 2 is replaced with an elastic sheet member such as a rubber sheet, which has a plurality of perforations at positions corresponding to the plurality of rods , thereby, the plurality of rods can be collectively and elastically contacted and supported by the elastic sheet member around its ring shape.

[0198] The diameter of each perforation in the elastic sheet member is designed to be about 10 to 30% smaller than the outer diameter of each rod. The elastic sheet (rubber sheet) has a thickness of about 1.2 mm and is made of, for example, NBR (acrylonitrile-butadiene rubber) with a rubber hardnes...

Abstract

The tactile pin display apparatus comprises; a rotary member 310 with plural tactile pins 301 movable up-and-down for displaying Braille points or the like, elastic O-rings 370 provided in the rotary member 310 for pressing and holding each of the tactile pins 301, three actuators 320 which is allowed to abut on the tactile pins 301 so as to protrude the tactile pins 301 at desired height from a tactile surface, a cam 330 which is allowed to abut on the tactile pins 301 so as to make the tactile pins 301 retreat toward the tactile surface, a selective drive means for selectively driving each of the actuators 320, and a rotary drive means for rotary driving the rotary member 310. The actuator 320 and the cam 330 are positioned near the rotary member 310, and a photocatalyst is provided on at least either the tactile pins 301 or the rotational member 310.

Description

technical field [0001] The present invention relates to a tactile pole holding device for holding a plurality of poles, such as 6 poles, 8 poles or more, and to a tactile pole display device for continuously displaying desired braille or normal (e.g. non-disabled) 2D or 3D characters and / or graphics of people). More particularly, the present invention relates to a touch rod retention and movement mechanism by which the rods are moved up and down from and toward a touch surface and maintained at a desired position or height from the touch surface. The present invention also relates to a braille display member capable of decomposing contaminants deposited on the rod or its peripheral portion. Background technique [0002] In a conventional braille display device, usually a touch stick display device, a plurality of braille cells, ie, display units, are arranged in a given number in a row (braille). Braille cells in a line (Braille) or a touch bar in a display unit (often sim...
