Abstract

Disclosed is a document cutting machine in which a cutting blade rotates. A safety mechanism for avoiding a danger to a human body is disclosed.

When the trash can is withdrawn, the operating piece of the actuator is installed in the trash can to regulate the relationship between the actuator and the micro switch in any case to stop the blade. A large stop switch is installed on the top plate for emergency stop, and the blade is instantly stopped even in case of an accident. The automatic operation is performed using the cam so as to detect the presence of the paper as the object and to rotate the blade surely from the insertion of the paper to the end of the cutting. When the trash can is bendable, a safety guide is provided to restrict the deformation to the inside of the trash can, thereby preventing the hand from getting into the bent portion.
