Abstract

PURPOSE:To realize a high speed input period irrespective of an input period of other signal, by constituting so that an input signal by a manual operation is inputted to a microprocessor through an input port which is provided separately. CONSTITUTION:Output voltage of a generator 5 which is rotated by a dial D for a manual operation is supplied to an instantaneous comparison type A/D converter 12, and its converted output is inputted to a microprocessor 1 through an input port 13. The converter is constituted of voltage comparators 14a-d and a reference voltage generating circuit 15. The circuit 15 provides reference voltages +V2, +V1 to inverted input terminals of the comparators 14a, 15b from its series circuit, and provides reference voltages -V1, -V2 to noninverted input terminals of the comparators 14c, 15d. When the dial D is rotated to the forward turn direction or the reverse turn direction, voltage being proportional to an operation speed of the dial D is instantaneously converted to a digital value, each instantaneous value is inputted at a high speed, and whenever it is inputted, it is adjusted. Accordingly, a variation value which has followed well a level of the input signal is obtained.
