摘要： In a device for detecting mirror position, there is provided a resistor substrate being located coaxially with a nut adjuster for adjusting an angle of incline of a mirror, and a contact member so as to nip the resistor substrate. The contact member slides in line corresponding to the movement of the nut adjuster while the resistor substrate is fixed to a housing. Thus, as the nut adjuster slides, the contact member slides against the resistor substrate, which results the change of a contact position of the contact member and a long resistance R1. Consequently, since a voltage level generated at the contact member changes, the angle of incline of the mirror can be determined by detecting this voltage level. Inasmuch as the contact member and the resistor substrate are housed within a sliding block, there is no need for much space to locate the various parts in, and thus the whole device can be configured in a compact manner.In addition, the fact that the resistance R1 is connected to the direct-current power source via resistances R2 and R3 means that the measured voltage level is acquired in the form of an intermediate value of the direct-current power source voltage. Subsequently, it is possible to reduce the influence of noise and other factors so that the mirror angle can be detected with a high degree of accuracy.
摘要翻译：在用于检测反射镜位置的装置中，设置有与用于调节反射镜倾斜角度的螺母调节器同轴定位的电阻基板和接触构件以夹持电阻基板。当电阻器基板固定到壳体时，接触构件在与螺母调节器的运动相对应的条件下滑动。因此，当螺母调节器滑动时，接触构件抵靠电阻器基板滑动，这导致接触构件的接触位置的变化和长电阻R1。因此，由于在接触构件处产生的电压电平变化，所以可以通过检测该电压电平来确定反射镜的倾斜角。由于接触构件和电阻器基板容纳在滑动块内，因此不需要很多空间来定位各种部件，因此可以以紧凑的方式配置整个装置。此外，电阻R1经由电阻R2和R3连接到直流电源的事实意味着以直流电源电压的中间值的形式获取测量的电压电平。随后，可以降低噪声等因素的影响，从而可以高精度地检测镜面角度。
