Title:
CUTTING MACHINE
Document Type and Number:
Japanese Patent JP2013071190
Kind Code:
A
Abstract:

To provide a cutting machine capable of improving safety more than before when a part of a human body enters an 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. Thus, 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 on a rib provided on a gear case 16, and restricts downward turning of a circular saw retaining part 13.
