2 and 3, the bulletin board according to the present invention, the base plate 10 and the cushion layer 20 and reinforcement, respectively, attached to the front and rear surfaces of the base plate 10 through an adhesive 40. It consists of the board | plate material 30 and the frame 50, and the said cushion layer 20 is provided with many holes 21 for frame attachment.

The holes 21 are formed in the vertical and horizontal directions so that the horizontal and vertical separation distances are constant in the cushion layer 20. The cushion layer 20 is made of foamed synthetic resin such as PVC, PE, or EVA. However, it is possible to achieve the environmental protection effect by mixing the powder of the waste tire, which is a recycled product, with an adhesive and molding it as a plate.

Here, although not shown, as in the conventional bulletin board, a separate surface material such as a fabric or a nonwoven fabric may be attached to the cushion layer, but the above-described material may be molded into a sheet of the cushion layer, and then various colors and patterns may be displayed. It is possible to obtain a bulletin board having a surface with excellent aesthetics without using a separate surface material.

Meanwhile, the picture frames attached to the bulletin board are shown in FIGS. 4 and 5.

Four projections 70 are formed on the rear surface of the frame 60 of the square-shaped frame 6 so that the frame can be fitted into the hole 21 formed in the bulletin board.

The frame 60 of the picture frame is formed of a front part 62, an upper part of which is opened and a lower part of which is closed, and a rear plate 65, and faces inwardly on the inner surfaces of the both side parts 64. Protruding partitions 66 are formed, respectively, and a space part is formed between the partition wall 66 and the back plate 65 and between the partition wall 66 and the front part 62, respectively, and the front part 62 located on the upper side. The locking jaw 63 is formed inside the lower end.

Therefore, when the sketchbook is to be inserted into the picture frame, as shown in FIGS. 4 and 6, the sketchbook 90 is inserted into the space between the partition 66 and the front part 62 on one side of the sketchbook 90. When the clip 91 such as a coil spring formed is inserted into the picture frame while being caught by the locking jaw 63 and the partition wall 66, and a picture or calligraphy work of a single sheet is inserted into the picture frame, it is shown in FIG. As described above, the piece of work 80 may be inserted into the space portion between the partition 66 and the back plate 65.
