In the sweep operation after turning on the ignition switch of the above-described cross-coil type instrument, it is not necessary to perform the step operation in each indicated angle unit by the step operation with a fine resolution. However, if the sweeping operation is performed by the drive torque from the drive processing unit that normally operates the cross-coil type instrument, the drive torque is large, and therefore the pointer is set against the electric indication angle (step operation). Overshoots, causing pulsation in the movement of the pointer, which gives the driver a feeling of discomfort. Therefore, in order to solve the above-mentioned problems, the present invention provides a cross-coil type instrument that does not give the driver a feeling of discomfort, and can enhance the product characteristics and designability.
