Abstract: A braille reading-writing device includes a body and a plurality of braille buttons. The body has a first surface and a second surface. The braille buttons are disposed through the body. Each of the braille buttons includes a pressing portion located at the same side with the first surface and a touching portion located at the same side with the second surface. The touching portion protrudes from the second surface when the pressing portion is pressed. The braille reading-writing device allows the blind people to write braille on the first surface and to touch to read the written braille on the second surface, thereby integrating the functions of writing and reading braille.
