2. Description of the Related Art Conventionally, a dot printer has been packaged in a cardboard packaging member for a dot printer, comprising a pair of buffer frames fitted on both right and left ends, and an outer case for accommodating the frames. It buffers shocks from the outside such as dropping and collisions during transportation to prevent damage.

[0003] Corrugated cardboard hardly exerts a cushioning effect in a flat state, but when bent into a rectangular tube shape, the strength is improved and an excellent cushioning effect is exhibited. The buffer frame of the cardboard packaging member for the dot printer also has a square tubular body obtained by bending a corrugated cardboard around a fitting portion to be fitted to the dot printer, and the dot printer is provided between the square tubular bodies. It has a structure in which a fitting portion is formed.

[0004]

However, the conventional cushioning frame is assembled by folding a single rectangular cardboard to reduce the number of parts and to prevent waste of material. The body is formed only on the front and rear parts of the buffer frame. For this reason, although the impact in the vertical direction has a relatively cushioning effect,
The shock from the front-rear direction, the diagonal direction, and the side surface causes the deformation of the buffer frame to be too large, so that the buffer effect cannot be exhibited.

In order to assemble a single corrugated cardboard into a complicated three-dimensional shape corresponding to the shape of a dot printer, it is necessary to form a large number of cuts, folds, insertion slits, and insertion pieces. As a result, it is difficult to maintain the strength of the cushioning frame, and the cushioning effect is reduced. In addition, the folding method becomes complicated, and there is a problem that the assembly is troublesome.

Therefore, in view of the above problems, the present invention forms a rectangular cylindrical frame around the buffer frame to increase the strength of the buffer frame so that it is highly resistant to impacts from up, down, left, right, and side. An object of the present invention is to provide a cardboard packaging member for a dot printer having a buffer frame that can exhibit a buffering effect, has a three-dimensional shape corresponding to the shape of the dot printer, is easily folded, and can be easily assembled.
