It is arranged in a position shifted to the left with respect to the

Further, the distance between the left and right inward folding lines m1 on the spine 13, the distance between the inward folding lines m1 and the outer folding lines m2, the central folding line n1 and the left and right folding lines in the rear partition sheet hinge portion 23 n2, the distance between the central folding line r1 and the left and right folding lines r2 in the front partition sheet hinge portion 33, and the distance between the central folding line s1 and the left and right folding lines s2 in the base sheet hinge portion 43. The spacing dimensions are set differently from each other.

As described above, the file according to the present embodiment has a double-foldable storage section sp including the base sheet 4 as the front sheet and the cover sheet 1 as the rear sheet. Then, the file is a guide mechanism that allows relative movement of the base sheet right half portion 42 and the back cover 12, which constitute at least the right half portion which is the first half portion when folded in two. Second guide mechanisms G1 and G2 are provided.

Therefore, in the present embodiment, the guiding action in the predetermined direction by the first and second guide mechanisms G appropriately guides the relative movement of the base sheet right half portion 42 and the back cover 12, thereby It is possible to provide a file in which both the sheet 4 and the cover 1 can take a suitable double-folding posture.

The first guide mechanism G1 is composed of a slit E provided in the base sheet right half portion 42 and a tongue piece 67 indirectly provided on the back cover 12 via the holding sheet 6 and inserted into the slit E. be.

Therefore, the first guide mechanism G1 can preferably guide the relative movement of the base sheet right half portion 42 and the back cover 12 in a predetermined direction by the relationship between the slit E and the tongue piece 67. It's becoming

A second guide mechanism G2 is a third holding sheet 6 fixed to the back cover 12 and having a folded portion 6a capable of engaging the upper edge je of the right half 42 of the base sheet.

Therefore, the second guide mechanism G2 allows the right half base sheet half 42 and the back cover 12 to be separated by the relationship between the upper edge je of the right half base sheet 42 and the folded portion 6a of the holding sheet 6. It can suitably guide relative movement in a predetermined direction.

A base sheet left half portion 41 and a front cover 1, which are second half portions of the base sheet 4, which is the front sheet, and the cover 1, which is the rear sheet, are fixed to each other.

Therefore, even when the storage portion sp is folded in two, the left half portion 41 of the base sheet and the front cover 1 are stably held at a constant relative position.

The base sheet 4, which is the front sheet, is set to be shorter in vertical dimension than the cover sheet 1, which is the rear sheet.

For this reason, the documents P stored in the storage part sp are excellent in readability. In this embodiment, a rear partition sheet 2 and a front partition sheet 3 having height dimensions similar to that of the cover 1 are arranged in front of the cover 1 . Therefore, in order to see the inside of the storage space sp, the upper half of each of the partition sheets 2 and 3 is positioned on the front side of the base sheet by folding the middle portions in the vertical direction of the rear partition sheet 2 and the front partition sheet 3 in the unfolded posture (T). It can be flexibly deformed so as to make it move.

It is constructed so that it can be opened and closed between an unfolded posture (T) in which the storage portion sp is not folded in half and a closed posture (F) in which the storage portion sp is folded in half, and the relative movement is in the unfolded posture (T ) and the closed posture (F).

Therefore, the back cover 12 that constitutes one half of the rear sheet, the right half of the base sheet that constitutes one half of the front sheet, and the right half of the base sheet 42 that constitute one half of the front sheet, , the rear partition sheet right half portion 22 and the front partition sheet right half portion 32, which constitute either the rear sheet or the front sheet, can move relative to each other in the left and right direction. can be preferably guided by the first and second guide mechanisms G1 and G2.

The present invention is not limited to the embodiments detailed above.

It goes without saying that the guide mechanism can adopt various configurations.

For example, the guide mechanism may be configured as shown in FIG.

Shown in FIG. 16 is a folder bound to a file. The holder can hold the document P by sandwiching it in the storage part sp. The holder has a storage part sp that can be folded into two at the center in the vertical direction and that includes a front holder sheet 7 as a front side sheet and a rear holder sheet 8 as a rear side sheet. The holder has a binding leg insertion hole 8a at the side end of the rear holder sheet 8, and is supported by the file body having binding legs (not shown).

The front holder sheet 7 is provided with a front holder sheet lower piece half 71 positioned below, which is one side of the storage part sp folded in two, and a front holder sheet upper piece half 72 positioned above, which is the other side. It is a thing. The rear holder sheet 8 is provided with a rear holder sheet lower half piece 81 positioned below one side of the storage part sp folded in two and a rear holder sheet upper half piece 82 positioned above the other side. It is a thing.

The front holder sheet lower piece half 71 and the rear holder sheet lower piece half 81 are fixed to each other at the welding portion y1 provided on the right side, and the front holder sheet upper piece half 72 and the rear holder sheet upper piece are fixed to each other. The half portion 82 is arranged so as to be relatively movable in a predetermined direction by a guide mechanism G3.

A guide mechanism G3 is provided between the front holder sheet upper half portion 72 and the rear holder sheet upper half portion 82 to guide the front holder sheet upper half portion 72 and the rear holder sheet upper half portion 82 so as to be relatively movable. is provided. The guide mechanism G3 has a vertically extending rail portion 72a provided on the side portion of the front holder sheet upper half portion 72 and a rail portion 72a provided on the rear holder sheet upper half portion 82, which is relatively moved in the vertical direction. and a rail holding portion 82a for holding the rail. Even with such a configuration, the intended purpose can be achieved.

The predetermined direction of relative movement permitted by the guide mechanism is not limited to the horizontal direction, and may be the vertical direction.

The guide mechanism may be provided not only on the first half half when folded in two but also on the second half half.

Of course, the front side sheet and the back side sheet are not limited to the base sheet and the cover sheet.

The guide mechanism may have a tongue directly or indirectly provided on the front sheet and a slit into which the tongue is inserted directly or indirectly provided on the rear sheet.

The third sheet is not limited to the holding sheet, and may be any sheet that has a folded portion that can engage the upper edge of the front sheet.

The second halves of the front sheet and the rear sheet may not be fixed to each other.

In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications are possible without departing from the scope of the present invention.
