Abstract
A pointer measuring instrument capable of indicating 'zero' on an indication panel by a pointer even if a play (backlash) is present in gears. The measuring instrument comprises a pointer reference position setting means () for determining the reference position of the pointer (). A control means () rotates the pointer () in the direction toward the reference position when a power supply to a stepping motor () is turned on, and performs a first drive for stopping the rotation of the pointer () when it receives a pointer reference position arrival signal from the pointer reference position setting means (). Then, the control means performs a second drive for moving the pointer () by a first angle from the reference position in the reverse direction away from the reference position, and performs a third drive for rotating the gear (S) of a reduction mechanism () on the stepping motor () side by a second angle.
