<p>PURPOSE:To make it possible that a user finds surely display characters and numerics outputted as sound output, by storing specific signals in a memory which stores sound. CONSTITUTION:The binary code of characters ''I AM A BOY'' is stored in memory M1, and the sound code of the characters above and a specific code using characters stored in M1 as a unit is stored in memory M2. When contents of M2 are read successively according to character arrangement sequence, the specific code is first read and is detected G1, and the output becomes ''1'' and is written in one memory of Johnson counter JC, and DD1 of dot display material DD is lit. Next, the sound code corresponding to ''I'' displayed on DD is read from M2 and is converted to a sound signal by CU and is outputted from speaker S. At this time, DD1 continues lighting, so that the operator can find surely characters and numerics which are outputted as sound.</p> |
