Patent ID: 8056388

Claim:
A pointer instrument comprising: a stepping motor, a pointer driven by rotations of the stepping motor via a speed-reduction mechanism including a plurality of gears, a display board having an index section to be pointed by the pointer, and control means that drives and controls the stepping motor, wherein pointer reference-position setting means are provided for determining a reference position of the pointer, and when the stepping motor is powered on or off, the control means performs a first drive process where the pointer is rotated in a direction of the reference position, and the rotation of the pointer is stopped with an input of a pointer reference-position arrival signal from the pointer reference-position setting means, then performs a second drive process where the pointer is moved from the reference position by a first angle in a direction opposite to the reference position direction, and then performs a third drive process where a gear at a side of the stepping motor of the speed-reduction mechanism is moved by a second angle.
