PURPOSE:To apply the titled device also to the confirmation of a braille constitution of a braille typewriter in addition to a studying device having the braille constitution, by providing the titled device with braille keys and a voice device and operating the voice device by the prescribed key constitution to confirm the braille constitution as voices. CONSTITUTION:A main key group 3 constitutes 6-point braille and is connected to a voice composing device in a circuit incorporated in a case 1, and if a prescribed key constitution is depressed, the Japanese syllabary such as ''a, i, u, e, o'' is generated. An auxiliary key group 4 indicates half tones, numerals, signs, etc. and is used to generate sonants, rho-sounds, contracted sounds, numerical sounds, etc. together with the main key group 3. Since a voice corresponding to a braille constitution using the keys 3, 4 is outputted immediately and precisely, the titled device can be used for a voice typewriter by incorporating it into a braille typewriter in addition to independent use as a studying device having the braille constitution, so that a blind person can check a braille constitution previously as voices and typing errors can be prevented. |
