Title:
計器装置
Document Type and Number:
Japanese Patent JP4412295
Kind Code:
B2
Abstract:

To reduce deviation of an indication position by a pointer caused by backlash on a rotation transfer route from a step motor to the pointer.

When mounting the pointer 60 on a pointer shaft 61, a state is set, wherein the backlash in the normal rotation direction of the step motor 40 on the rotation transfer route is minimized, and the backlash in the reverse rotation direction is maximized. Hereby, when driving the step motor 40 in the normal rotation direction, the backlash on the rotation transfer route is not required to be taken into consideration. On the other hand, when driving the step motor 40 in the reverse rotation direction, deviation of the indication position caused by the backlash on the rotation transfer route can be reduced by using an angle to which a compensation angle for compensating the backlash on the rotation transfer route is added, as a target angle.
