Abstract

PURPOSE: A marking detector having one sheet of piezoelectric vibrating plate glued or contacted at one point of a glass sheet whose circumference is clamped and which has simple construction and operates accurately. Detection of whether or not glass sheets are broken is made with reflection wave by vibration of the piezoelectric vibration plate.
