When the second leg piece 40A is further lifted, the first leg piece 30A is lifted by the second leg piece 40A from the lower side 33 side. After confirming the separation of the side edges 32, 32 of the first leg piece 30A from the base 10, a mountain fold is performed along the upper edge 31 of the first leg piece 30A.

Next, as shown in FIG. 12, after the tip of the second leg piece 40A is placed on the lower surface side of the pedestal portion 14, the side plates 44, 44 are valley-folded along the side edges 42, 42. At this time, by inserting the pedestal portion 14 into the locking groove 48 while bending the side plates 44, 44 obliquely, the pedestal portion 14 can be inserted from the opening 481 of the locking groove 48.

Then, after inserting the tip of the pedestal portion 14 into the engaging portion 483 of the locking groove 48, the tip portions 471 of the stopper portions 47, 47 correspond to the side edges 32, 32 of the first leg piece 30A of the base 10. By making contact with the punching hole 32a, the side plates 44, 44 are fixed in an inverted C shape, and the page holder 46 is attached to the front surface of the pedestal portion 14 in an inverted C shape.

According to this, by inserting the installed portion such as a musical score into the locking groove 48 and placing it on the pedestal portion 14, it is possible to prevent the installed object from being turned over and to reliably support it.

As can be seen from the above-described embodiments, according to the present invention, one thin sheet is formed by forming leg members of the same shape with, for example, Thomson blades at a plurality of locations on the base made of a thin plate material (preferably thick paper). A book table made of a plate material can be manufactured at low cost. Then, when not in use, each leg member is included in the base so that almost one piece of the leg member is brought into a state in which it can be easily carried in a bag or the like.

When using, the first lower side of the first leg is cut and raised to the back side of the base through the fold line of the first upper side, and then the second upper side of the second leg is folded to the second lower side. By cutting and raising from the inside of the first leg piece to the surface side of the base via a wire, and locking the bottom edge of the base to the slit provided in the support portion of the second leg, the base is set at a predetermined angle. It can be assembled in a tilted state.

Further, since the supporting portion of the second leg piece is provided with the page holder for preventing the pages of the book of interest from being turned over, it is possible to stably set the book of interest such as a musical score in the open state. .. Furthermore, by making it possible to fold the base in A3 size or larger from the central part, you can carry it in A4 size when carrying it, and when using it, spread it to A3 size to open it in a spread. A3 size paper can be set.
