Title:
CUTTING MACHINE
Document Type and Number:
WIPO Patent Application WO/2013/046523
Kind Code:
A1
Abstract:
When part of a human body enters an entry-prohibited region, a blade is reliably prevented from approaching the part of the human body in the entry-prohibited region. When a hand enters an entry-prohibited region in a state in which electric power of a tabletop cutting machine is turned on, a human-body detecting infrared sensor 7 provided on a front part of a holder 5 detects infrared rays generated by the hand or the like and outputs a restricting signal. As a result, the electric power supply to electromagnets embedded in the holder 5 is cut off, a pin 18 projects in a direction parallel to a shaft 12 by biasing of a spring, abuts a rib provided on a gear case 16, and restricts downward turning of a circular saw retaining part 13.
