By folding the right end(12) of the upper panel(10) downward, the left end(44) of the right panel(40) upward, the ends(12,44) are butted each other to be compressed. Further the left end(21) of the lower panel(20) is folded to upward, the left panel(30) downward, correspondingly the ends(21,34) are butted to be compressed, subsequently the upper panel is transmitted by the transmitter to be separated at the regular intervals upward from the downward panel.
