RECORDING MATERIAL DETERMINATION APPARATUS AND IMAGE FORMING APPARATUS THAT RECEIVE ULTRASONIC WAVES
Publication number: 20200209794Abstract: A recording material determination apparatus includes a transmission unit, a reception unit, and a determination unit. The transmission unit transmits an ultrasonic wave to a recording material. The reception unit vibrates when the reception unit receives the ultrasonic wave having been transmitted from the transmission unit and having passed through the recording material, and outputs a signal corresponding to a vibration state. The determination unit determines a basis weight of the recording material in accordance with the signal output from the reception unit. A resonance frequency of the reception unit differs from a resonance frequency of the transmission unit, and the reception unit is capable of receiving a sound wave in an ultrasonic range and a sound wave in an audible range.Type: ApplicationFiled: December 17, 2019Publication date: July 2, 2020Inventors: Junya Azami, Masafumi Monde, Hiromitsu Kumada, Yuka Fujii, Mizuki Ishimoto -
