Claims

[Scope of utility model registration request]

In a paper cutting device that cuts recording paper using a lower blade that rotates in response to a driving force and an upper blade that rotates together with the lower blade in pressure contact with a cylindrical side surface of the lower blade, an angle that supports the upper blade is rotatably supported, and the angle that supports the upper blade is rotatably supported; A swing pin provided on the angle, a swing cam that is rotated by a rotary solenoid and restricts the rotational movement of the angle by applying an external force to the swing pin, and a rotation center of the angle and the swing pin. A paper cutting device characterized in that the positional relationship between the center of the angle and the rotation center of the swing cam is such that a rotational moment of a restoring force acting on the angle is canceled out.
