Abstract
An indicating device in a measuring machine in which the flickering of an indicated value due to vibrations of the machine and the like is avoided. The indicating device includes a flickering sensing circuit for receiving up signals or down signals outputted from an encoder as input signals thereto and sensing the change in the signals from the up signals to the down signals and vice versa. When the change in the signals is sensed by this flickering sensing circuit, a hold signal having a predetermined period of time is outputted from a hold circuit, whereby renewing storage of counted values from the counter by a latch circuit is interrupted for a predetermined period of time.
