Abstract
Official abstract text for this publication.
A recording material determination device includes an ultrasonic wave transmission unit configured to transmit an ultrasonic wave to a recording material based on a driving signal, an ultrasonic wave receiving unit configured to receive the ultrasonic wave, a light exposure unit configured to expose the recording material to light, a light receiving unit configured to receive light, an amplification unit configured to amplify an ultrasonic wave received by the ultrasonic wave receiving unit to a first output value, and after the amplification unit amplifies the ultrasonic wave received by the ultrasonic wave receiving unit to the first output value, a control unit performs control so as to obtain the second output value by the light exposure unit and the light receiving unit during a period of time after the amplification of the ultrasonic wave is stopped and before the next ultrasonic wave comes to be transmittable.
First claim
Opening claim text (preview).
What is claimed is: 1. A recording material determination device comprising: an ultrasonic wave transmission unit configured to transmit an ultrasonic wave a plurality of times to a recording material; an ultrasonic wave receiving unit configured to receive the ultrasonic wave transmitted via the recording material after the ultrasonic wave is transmitted by the ultrasonic wave transmission unit and output a first signal and a second signal corresponding to the ultrasonic wave r…
