    • An IC card reader that can output data in an audio form. The IC card reader includes a small portable case in which an IC card can be inserted. A microcontroller powered by a battery within the case reads the stored data from the IC card and encodes the read data into a series of voice commands. A voice synthesizer circuit produces a synthetic speech signal from the encoded data. Thus, in use of the IC card reader, when a button is depressed to close a switch, the microcontroller is caused to interrogate the card so that the data stored on the card is read into the microcontroller. The microcomputer produces a synthetic speech signal that is amplified by the amplifier and output by the speaker as synthetic speech which can be heard by the user by holding the card reader with the speaker against the user's ear.
    • 可以以音频形式输出数据的IC卡读卡器。 IC卡读取器包括可以插入IC卡的小型便携式外壳。 由案例中的电池供电的微控制器从IC卡读取存储的数据,并将读取的数据编码为一系列语音命令。 语音合成器电路从编码数据产生合成语音信号。 因此,在使用IC卡阅读器时,当按下按钮以闭合开关时,使微控制器询问卡,使得存储在卡上的数据被读入微控制器。 微型计算机产生由放大器放大器并由扬声器输出的合成语音信号,作为合成语音,用户可以通过将读取器与扬声器握在用户的耳朵上而被用户听到。
