(Problems to be Solved by the Invention) In the above-mentioned simple binding machine 1, the tape 6a is cut by the cutting blade 14 after wrapping the tape 6a around the outer periphery of the object 17 to be bound. The objects 17 to be bound slightly come into contact with the screw heads of the screws 13 that attach the guard plate 16 to the binding table 8. This becomes noticeable when the tape 6a is cut at a position close to the objects 17 to be bound, and if the cutting point is placed away from the objects 17 to be bound, strong force is required to cut the tape 6a, and Thing 1
Unnecessary force is added to 7. For this reason, there has been a problem in that the objects 17 to be bound are damaged when binding leafy vegetables such as chives and spinach, resulting in a decrease in commercial value.

In view of the above, the purpose of the present invention is to solve the above problem by attaching a tape guide plate that also serves as a cover for the screw head to the mounting side of the screw 13 so that the object to be bound 17 does not come into contact with the screw head of the screw 13. An object of the present invention is to provide a tape cutting device for a simple binding machine.

(Means for Solving the Problems) As a means for solving the above problems, the present invention provides a tape cutting device in which a cutting blade is removably attached to the end of a binding table with a screw.
A substantially vertical mounting surface that closely contacts the cutting blade is formed, and the upper portion of the mounting surface is bent and further bent downward continuously from the bent portion so as to cover the head of the screw to form a guide portion. The present invention is characterized in that the mounting surface is provided with a groove having a width to which the head of the screw is engaged.

(Function) Since the present invention is constructed as described above, the cutting blade is attached by closely contacting the cutting blade to the mounting surface and adjusting the height relationship between the cutting blade and the guide part through the long hole provided in the mounting surface. This is done by simultaneously fastening the cutting blade and the mounting surface to the binding table. By fastening the attachment surface to the binding base with screws in this manner, the heads of the screws are covered by the guide portions, so that objects to be bound will not come into contact with the heads of the screws. When replacing the cutting blade, the cutting blade can be easily removed by removing the screw. Further, since the cutting blade is sandwiched between the attachment surface and the binding base, the amount of protrusion thereof is constant to the amount most suitable for cutting the tape, making it easy to cut the tape.
