Rotary cutter device

A rotary cutter device comprising:

• a housing:
• a rotator supported by said housing rotatably in a predetermined rotating direction and having a rotary blade including a first blade edge part;
• and
• a holding body supported by said housing and having a fixed blade including a second blade edge part, wherein
• said first blade edge part is brought into contact with said second blade edge part from one side in said rotating direction and the first blade edge part and the second blade edge part are rubbed with each other so as to cut an object to be cut located in a path passing through the vicinity of said second blade edge part to have a cut object;
• and
• a rotation-side separating member is provided on said rotator by a predetermined delay phase angle from said rotary blade and brought into contact with said cut object in which a cut portion of the cut object adheres to said first blade edge part during said cutting on a first side of said first blade edge part facing a direction of rotation and rotating together with said rotary blade and applying a reaction force to said cut object toward a second side opposite to said first side, and
• a fixed-side separating member is fixed to said housing so as to be located outside a rotation range of said first blade edge part of said rotator and in the vicinity of a rotation radius of the first blade edge part, and is brought into contact with said cut object from said first side and constrains movement of said cut object to the second side.
