Of course, it is also possible to do so.

(Effect of the invention) As described above, in this invention, the back of the inner periphery of the picture frame body serves as a drawing board receiving surface for receiving the drawing board, and a positioning wall for positioning the drawing board is erected on the outer peripheral side of the drawing board receiving surface. This prevents the drawing board from shifting its position.Moreover, a recess is formed in the positioning wall from the inner circumferential side to the outer circumferential side, and the left and right walls facing the outer circumference of this recess are engaged from the inside to the outward. An insertion head that fits into the engagement groove is integrally formed at the tip of a drawing board holding piece that presses the back of the drawing board when the drawing board is fitted into the drawing board receiving surface of the picture frame frame formed with the engagement groove. It is made by fitting a drawing board holding member made of
Since the thickness of the insertion head is formed to be slightly smaller than the width of the engagement groove, and the width of the insertion head is formed to be slightly larger than the width of the engagement groove, the rotation of the insertion head is caused by the engagement groove. As a result, the drawing board is pressed against the drawing board receiving surface, and can be held without the need to make cuts in the drawing board. Moreover, since the width of the insertion head is formed to be slightly larger than the width of the engagement groove, when removing the drawing board, just hold the drawing board holding piece of the drawing board holding member and lift it up a little forcefully, and the insertion head will be forcibly removed. It can be rotated and the drawing board can be removed.

Furthermore, since the present invention only requires inserting the drawing board holding member into the engagement groove of the picture frame frame, the number of parts is small and installation is easy, as no tools are required.

Furthermore, both the picture frame frame and the drawing board holding member can be integrally molded from plastic, and no metal parts are required, making it suitable for mass production.
