The file 610 is provided with a dripping prevention means 630 for preventing the binding object S from drooping when the binding tool 9010 is erected in the length direction. When one cover cover 616 abuts against the binding margin side edge S1 of the binding object S bound by the binding tool 9010 and the other cover cover 616 is closed, the other cover along the binding tool 9010 is closed. A pressing means 730 that presses the object to be bound S toward the back cover 618 is formed on the inside of the cover 612 so as to be undulated.
In this embodiment, the sag prevention means 630 and the pressing action means 730 are configured as an integrated sag prevention pressing action member.
The sag prevention pressing action member has an upper end edge and a lower end edge, and is formed in a rectangular shape in which the upper end edge and the lower end edge are parallel.
When the front cover 616 of the file cover 612 is folded and closed at the front thin hinge portion 620, the sagging prevention pressing member is reduced in angle between the front cover 616 and the back cover 614 from about 180 degrees to about 90 degrees, Corresponding to the bending, the file cover 612 is formed so as to bend along the front thin-walled hinge portion 620 and protrude toward the binding margin side edge S1 of the binding object S.

The sag prevention means 630 is constituted by a rising member constituting the sag prevention means attached to the inside of the front cover 612, and a rising part that is spanned between at least two of the front cover 616, the back cover 618, and the back cover 614. Have
One rising portion is connected to one of the front cover 616, the back cover 618, and the back cover 614, and the other rising portion is the front cover 616, the back cover 618, and the spine 614 that are not connected to the one rising portion. Connected to one of them.

  The dripping prevention means 630 is defined by a separation slit 690 that follows the back cover 618 and the spine 614 to which the binding tool 9010 is attached. The separation slit 690 is below the binding tool 9010, and from the vicinity of the center of the first binding ring 9012 and the second binding ring 9014 of the spine cover 614 to the back cover 618 side, to the back cover 618 and the spine cover 614. It is constituted by an elongated through hole that is continuously orthogonal to the front thin-walled hinge portion 620, and forms a rising portion that extends between the front cover 616 and the back cover 618.

  The sag prevention means 630 is bent inward at the center so that the region separated by the separation slit 690 rises in a mountain shape from the inner surfaces of the back cover 614 and the back cover 618 to the rising portion. A first bent portion 640 to be attached, a third bent portion 644 that connects an end of the separation slit 690 on the back cover 618 side and a lower end edge of the dripping prevention means 630, and an edge on the spine cover 614 side of the separation slit 690 And a second bent portion 642 that connects the lower end edge of the sag prevention means 630 is formed.

The first bent portion 640, the second bent portion 642, and the third bent portion 644 are formed in parallel, and when viewed from the inside of the cover 612, the first bent portion 640 becomes a mountain fold toward the inner side, and the second bent portion. 642 and the third bent portion 644 are valley-folded.
In other words, a first bent portion 640 is formed between the holding portion 632 formed of the one rising portion in the plan view and the support portion 634 formed of the other rising portion in the plan view.
Furthermore, the support part 634 has a first connection part 650 for connection to the front cover 616 at an end edge opposite to the first bent part 640, and can be bent in the vicinity of the first connection part 650. Therefore, a second bent portion 642 is formed. The second bent portion 642 is formed continuously with the front thin hinge portion 620.
Further, the holding portion 632 has an area for contacting the binding margin side edge S1 of the binding object S and pressing the binding object S to the outside of the cover 612, and extends in the length (D) direction of the binding tool 9010. The binding tool 9010 has a length extending in the height (G) direction corresponding to the length and the thickness of the stacked objects S to be bound. The holding portion 632 has a second connecting portion 652 for connecting to the back cover 618 at the edge opposite to the first bent portion 640, and can be bent in the vicinity of the second connecting portion 652. Therefore, a third bent portion 644 is formed.
