Abstract
A motion detecting device comprises an encoder for generating two signals of A phase and B phase, 90.degree. out of phase with each other, when a member being measured is subject to an inclination or swaying. A pulse generation section generates a positive pulse or a negative pulse, depending on the direction of the inclination, at each of the leading and trailing edges of the A phase and B phase signals. An up/down counter counts up or down the positive or negative pulses, respectively, and an inclination detection section outputs an inclination generation signal when the member being measured is sufficiently inclined, in either a positive or negative direction, so as to cause a counter value to be above a first set value or below a second set value.
