The situation of position and in the case of being in the second position, display part 31a does not moves.It addition, the upper end of mobile member 31 and formation
Retainer 11c on box body 11 abuts, and the uppermost position of display part 31a is positioned.Whereby, can make clearance G 1 and
Clearance G 2 is almost nil, is possible to prevent the excessive stowage of sheet material.That is, according to this box 10, keep from being kept component 18 at middle plate
Primary importance when moving to than the primary importance second position on the lower, middle plate 12 and display part 31a do not interlock.Therefore, i.e.
Make middle plate 12 be positioned at primary importance, also there is no need such as to arrange between display part 31a and through hole 11b gap, and can
Prevent the excessive stowage of sheet material S.Further, since except middle plate 12 downward from primary importance to the second position time in addition to, aobvious
Show that portion 31a interlocks with middle plate 12 via cursor 33, so, from full load condition until sheet material surplus becomes 0, Ke Yilian
Distinguish the sheet material amount in box 10 continuously.
It addition, in the present embodiment, the base end part at the first abutting part 33a is formed with elastic 33c, but, not
It is confined to this, as long as form elastic at certain position of linkage part 50.For example, it is possible to will be at middle plate 12 from primary importance
Move to the elastic of elastic deformation during the second position and be arranged on the 3rd abutting part 33d side of cursor 33, it is also possible to be arranged on
On the rib 31b of mobile member 31.
It addition, in the present embodiment, constitute cursor 33 and mobile member 31 with component independently, but, also
Cursor 33 and mobile member 31 can be constituted by a component.Alternatively, it is also possible to do not make during cursor 33 with rotary shaft 32 is
The heart rotates, but can constitute the most slidably and movingly.
It addition, in the present embodiment, the sheet material that through hole 11b through for display part 31a is arranged on box body 11 is entered
