One end is bent into a ring shape, and a plurality of support grooves 11 through which the binding rod 3 can be inserted are provided at predetermined intervals in this bent portion 1a, and the shaft 4 is inserted into the center of the bent portion 1a. The second support body 2 has the other end of the plate body raised upward, and an opening 21 for receiving the binding rod 3 in the raised part 2a.
A plurality of support holes 21 having diameters a are provided at predetermined intervals, and the binding rod 3 is formed of a narrow metal plate having a through hole 3a at one end.

The first and second supports 1 and 2 may be formed of a single plate, or may be formed separately and connected by a connecting plate, or may be attached separately.

Moreover, these supports 1 and 2 are formed of metal plates,
It may also be formed by molding using other synthetic resin materials.

Therefore, the support hole 21 of the second support body 2 is a long hole larger than the cross-sectional shape of the binding rod 3, and when the binding rod 3 is inserted into the support hole 21, the binding rod 3 can be moved upwardly and downwardly. It can be moved left and right, and this support hole 21
The opening 21a is located at the upper part of one side of the housing.

Further, the binding rod 3 is rotatably supported on the first support body 1 by inserting the shaft 4 into the through hole 3a provided at one end thereof, and a knob 5 is provided at the tip of the binding rod 3. is provided so that it can swing freely.

This knob 5 is provided at one end with a circular locking portion 5a that protrudes into the support hole 21 of the second support body 2 and is smaller than the support hole 21, and this locking portion 5a allows the binding rod 3 a recessed portion 5b extending in the axial direction from the end surface of the locking portion 5a;
and a pin 51 that crosses the recessed part 5b, and the knob 5 is attached to the binding rod 3 to freely swing through the pin 51, and by swinging the knob 5 around the pin 51, The locking portion 5a is configured to be detached from the support hole 21.

The locking portion 5a provided on the knob 5 may be formed into a circular shape as described above and inserted into the support hole 21, or alternatively, the lower part of the circular locking portion may be cut out and the locking portion may be inserted into the support hole 21. At this time, the end surface of the cutout portion may come into contact with the outer surface of the raised portion 2a of the second support body 2 to prevent the locking portion from moving within the support hole 21, or one of the knobs 5 may The end surface may be used as a locking portion, and this locking portion may be elastically pressed against the outer surface of the upright portion 2a, and the binding rod 3 may be supported by the second support body 2 by this pressing force.

Further, when the locking portion 5a is inserted into the support hole 21, the support hole is formed in a concave shape by extending the opening portion 21a,
The raised portion 2a around the support hole may be recessed toward the first support body 1, and the locking portion 5a may be inserted into the recessed portion.

6 in the figure is a cover consisting of a front cover 6a, a back cover 6b, and a spine 6c, and a notch 61 is provided at the upper end of the spine 6c.
is provided.

The present invention is constructed as described above, in which the first and second supports 1 and 2 are attached to the spine 6c, the knob 5 is arranged in the notch 61, and the knob 5 is located at the upper edge of the cover 6. This prevents the knob 5 from protruding from the notch 61, and allows the knob 5 to be pivoted from the notch 61.

However, when binding publications such as weekly papers and monthly papers, the locking part 5a of the knob 5 protruding into the support hole 21 of the second support body 2 is removed from the support hole 21 as shown in FIG. First, lift the knob 5 along the support hole 21,
When the knob 5 is pivoted about the pin 51 in a direction perpendicular to the length direction of the binding rod 3 while the locking portion 5a is in contact with the upper surface of the support hole 21, the locking portion 5a is removed from the support hole 21. After separation, only the binding rod 3 is inserted into the support hole 21, and in this state, using the knob 5, insert the tip of the binding rod 3 into the opening 2.
It is extracted from 1a to the outside.

Then, insert the binding rod 3 into the binding section at the center of the number of pages in the publication, and insert the tip of the binding rod 3 into the opening 2.
