Abstract
A human presence sensor unit in which an ultrasonic wave sensor is mounted is fixed to a frame sheet metal of an image forming apparatus with a pedestal interposed therebetween. The pedestal is made of a synthetic resin material, and the frame sheet metal is made of a metal material. As the pedestal and the frame sheet metal are made of different materials, a difference in the acoustic impedance is produced between the pedestal and the frame sheet metal.
