PURPOSE: To form an opening surface from which a content is taken out on a sealed bag which is filled with a food or powdery object to be used in the field of drugs, etc.
CONSTITUTION: Moving mechanisms 12, 13 are provided which can reciprocate a cutter 11 to form a cutter line on a bag surface in the X axial direction and Y axial direction which is orthogonal to the X axial direction, on a base plate 5 which is vertically movable to a bag filled with a powder object, and has an opening 10 to open the bag. Then, a cutter driving mechanism 3 to which a vertical moving and turning mechanisms for the cutter 11 are attached is provided on the moving mechanism 12. At the same time, a bag turn-over mechanism 4 with a gripping member 50 to turn over a bag piece 44 which is formed on the bag surface is provided at the opposite location to the moving mechanism 12 across the opening 10.
