Abstract:
The timing of obtaining an output value for use in a determination of a recording medium is generated from a received ultrasonic wave and a waveform generated by delaying the ultrasonic wave, whereby it is possible to reduce an influence of a reflection wave from the peripheral members and an influence of a change in the environment to improve the accuracy of determination of the recoding medium.
