<p>PURPOSE:To make a prescribed data output by means of not only printing but also a sound exactly, by outputting a character, etc. by means of a sound, in case when it has been decided that the indicating bit has a sound output logical value, by the decision circuit. CONSTITUTION:A data from CPU is converted to a parallel data by the buffer register 2, is stored in the address according to an address data of the microprocessor 4, and is input at every one character to the printer 3 in accordance of the command of the processor 4. At this time, when print-out of one character portion is finished, a ready signal RDY1 is sent to the processor 4. In this way, the processor 4 detects print-out of one character portion, and sends the next character data to the printer 3. On the other hand, an output of the register 2 is sent to the sound output decision device 5 once again. And when it is decided that the indicating bit has a sound output logical value, this output is displayed by a sound from the speaker 10 by the sound generator 7 through the processor 4. Thus, a prescribed data can be output by means of not only printing but also a sound exactly.</p> |
