Abstract
One object is to detect a sheet with high precision by using ultrasonic waves. A sheet processing apparatus detects a paper sheet based on a change in ultrasonic waves. The sheet processing apparatus includes a support member that supports a sheet. A through part is formed in the support member. The sheet processing apparatus further includes a transmitting unit that transmits ultrasonic waves from a transmitting surface; a reflecting unit that reflects the ultrasonic waves, which were transmitted from the transmitting unit and passed through the through part; and a receiving unit that receives on a receiving surface the ultrasonic waves reflected by the reflecting unit. The receiving surface faces downward, and the transmitting surface is parallel to a vertical direction or faces downward, or the transmitting surface faces downward, and the receiving surface is parallel to a vertical direction or faces downward.
