ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a clip device that bends a clip plate and clips a bundle of sheets together with the bent dip plate.
2. Description of the Related Art
Conventionally, a clip machine which clips the end portions of a plurality of sheet members together is known (see Japanese Utility Model Publication No. SHO 47-12089). This clip machine, as shown in
FIGS. 76 and 77
, is equipped with a handle
2
provided in one end of a base
1
so that it is rotatable, and a cover
3
provided between the base
1
and the handle
2
. A guide groove
4
is formed in the upper surface of the base
1
, and between this guide groove
4
and the cover
3
, a clip-connected member
5
is housed. This clip-connected member
5
is formed by connecting a plurality of clip members
5
N together with an adhesive agent as in staples, each clip member
5
N being bent into a U shape.
The other end (rear end) of the dip-connected member
5
is in contact with a clamp member
7
provided slidably on a push rod
6
shown in FIG.
78
. This clamp
7
urges the clip-connected member
5
in the left direction (in
FIG. 77
) by a sprig
9
provided on the push rod
6
. This urging causes one end (front end) of the clip-connected member
5
to be in contact with one end
4
A of the guide groove
4
.
A push plate
8
is provided on the lower surface of the handle
2
. If the handle
2
is rotated from a solid line position in
FIG. 76
to a broken line position, the push plate
8
will make contact with the bent proximal portion of the leading clip member
5
N of the clip-connected member
5
and separate the clip member
5
N from the clip-connected member
5
. And this separated clip member
5
N alone is further compressed and deformed by the pushing force of the push plate
8
, so that the end portions of a sheet bundle are clipped together by the deformed clip member
5
N.
Incidentally, if sure clipping by the clip member
5
N is to be obtained, the clip member
5
N must be widened and formed into a plate shape. However, if the clip member
5
N is widened, the number of clip members
5
N that can be housed will be reduced and the clip-connected member
5
must be frequently supplied. Accordingly, there is a problem in that it will result in a great inconvenience.
Also, this clip member
5
N clamps a sheet bundle by inserting the sheet bundle into the clip member
5
N and crushing the bent proximal portion
5
N
a
. Therefore, if the sheet bundle thickens, the bent proximal portion Na cannot be sufficiently crushed. For this reason, there is a problem in that sufficient clipping force cannot be obtained, so that the sheet bundle is easily separated from the clip member
5
N.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a clip device which is capable of clipping a sheet bundle with more than a predetermined clipping force independent of the thickness of the sheet bundle.
Another object of the invention is to provide a clip device which is capable of housing a great number of clip plates into a cartridge so that frequent supply of the clip plates to the cartridge is not needed
The clip device according to the present invention comprises: a cartridge for housing a plurality of substantially flat clip plates; feed means for feeding the clip plates from the cartridge into a predetermined position; bending means for bending the clip plate into a shape in which only point end portions are closed and also a rear portion is bulged; and dip means for clipping a sheet bundle by opening the point end portions of the bent clip and then inserting the sheet bundle into the opened point end portions.
