Abstract
A received beam amount acquisition sectionacquires a received beam amount per unit time of a beam receiverat certain sampling time intervals. A beam shielding detection sectiondetects presence or absence of beam shielding of a monitoring beam B by determining whether or not the acquired received beam amount per unit time of the beam receiver is lower than a determination threshold Th for detecting the presence of beam shielding of the monitoring beam B. A detection sensitivity of the beam shielding detection sectionis configured to be switched from a normal sensitivity mode to a high sensitivity mode when bending is initial processing based on a predetermined processing program, and an acquired height position of the beam receiveris lower than a predetermined second height position LP
