Abstract
A power transmitting apparatus includes a power transmitting section that includes an input shaft section and an output shaft section and transmits drive force from the input shaft section to the output shaft section, a first detection section including a polarizing section that rotates when one of the input shaft section and the output shaft section rotates and has a polarization characteristic, a light source section that irradiates the polarizing section with light, and a light detection section that outputs a signal according to the intensity of the light from the polarizing section, a second detection section that outputs a signal according to the rotational state of the other one of the input shaft section and the output shaft section, and a determination section that determines the rotational state of the polarizing section based on the signal from the light detection section and the signal from the second detection section.
