ABSTRACT:
A device for displaying information by a hand which is driven by a stepping motor in both forward and backward directions and which moves within a limited range, in which the stepping motor receives a driving signal enough to move and scan the hand in one direction in the whole range of the limited region for facilitating the attachment of the hand, and depending on the object to be measured, overtravel inhibiting circuit means are added to prevent any misdisplay.
