DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus for forming an image corresponding to an input image on a transfer paper, such as a copying machine, a printer, a facsimile machine, etc., and more particularly, to an accessory holder of the image forming apparatus. .

[0002]

2. Description of the Related Art Among image forming apparatuses, especially in copying machines and facsimile apparatuses for recording an original image on transfer paper, when handling an original, a metallic material such as a clip or a staple, which is a binding device for the original, is used. It is necessary to remove the binding device and provide a place for placing the binding device. Conventionally, in order to provide a binding device mounting portion on the upper surface of the outer cover of a copying machine and to prevent scattering of binding devices, Japanese Patent Application Laid-Open No. 60-104962 and Japanese Utility Model Application Publication No.
As described in JP-A-8-36741 and JP-A-56-40532, there is known a technique in which a magnet is provided on the mounting portion to absorb a binding tool.

[0003]

However, in the above-mentioned prior art, since the binding device is attracted by the magnet provided on the binding device placing portion, the binding device placed on the placing portion is not used. When taking out, there is a problem that it is difficult to take out.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a small article storage portion of an image forming apparatus which prevents scattering of a binding tool on the image forming apparatus and facilitates removal of the binding tool.

According to a first aspect of the present invention, there is provided an image forming apparatus comprising:
The magnet has an axis parallel to the bottom surface of the recess.
It is rotatably supported as a core,
The means may be configured so that the magnet has a magnetic field line from the magnet,
The magnet is rotated between a position where
It is a rotating means for causing the rotation.

[0005]

A magnet is provided inside the exterior cover so that a magnetic force acts on the bottom surface of the recess formed in a part of the exterior cover, and a small metal object such as a clip is placed on the bottom surface of the recess by the action of the magnet. Adsorb. When taking out small items from this recess,
The magnetic force from the magnet to the recess is cut off by a cut-off means for selectively cutting off the magnetic force, so that small articles can be easily taken out.

[0006]

FIG. 1 is a perspective view of a copying machine as an image forming apparatus according to an embodiment of the present invention. In FIG. 1, a concave portion 2 on which small metallic objects such as clips and staples are placed is formed in an outer cover 1 on the upper surface of the copying machine. This recess forms a part of an exterior cover made of a resin material such as ABS resin or Noryl resin. On the side of the copying machine, there is provided a knob 3 for operating so as to selectively block and open the magnetic force of the magnet. FIG. 2 shows a partial sectional view of the recess 2 and the magnet. In FIG. 2, a magnet 4 is located at a position facing the recess 2 with the outer cover upper surface 1 of the copying machine therebetween.
Is provided. The magnet 4 is mounted on a lever 5, and the lever 5 is rotatably mounted on a rotation shaft 6 implanted from the exterior cover 1 as a fulcrum. The other end of the lever 5 projects from the side surface of the exterior cover, and this portion constitutes the knob 3.

In FIG. 3, when the magnet 4 and the lever 5 are at the positions indicated by the solid lines, the magnetic force of the magnet 4 acts on the recess 2, and the metallic binding tool placed in the recess 2 is attracted to the recess 2, This prevents scattering of binding devices. When removing the binding tool from the recess 2, the knob 3 is operated to the position indicated by the broken line. As a result, the lever 5 and the magnet 4 attached to the lever move to the position indicated by the broken line, the magnetic force acting on the recess 2 is cut off, and the magnetic force acting on the binding is also cut off. Can be easily removed from Therefore, according to the present embodiment, since the binding device is attracted by the magnetic force, scattering of the binding device can be prevented, and when the binding device is taken out, the magnetic force is shut off. Become.

FIGS. 4 and 5 show a modified embodiment of the present invention, and a description of the same configuration as the embodiment of FIGS. 1 and 2 will be omitted. 4 and 5, a spring receiving portion 7 is implanted in the lever 5, and a spring 8 is stretched between the spring receiving portion 7 and the side surface of the exterior cover. 9
Is a stopper implanted on the inner surface of the upper surface of the outer cover. As shown in FIG. 5, the spring 8 is in a contracted state when the magnet 4 is at a position facing the recess 2 (solid line) and when the magnet is at a position where the magnetic force is cut off (dashed line).
Further, further movement is restricted by the stopper 9. Therefore, due to the action of the spring, the magnet 4 and the lever 5 do not take the position indicated by the dashed line, but take either the position indicated by the solid line or the position indicated by the broken line. Operability is improved.

FIGS. 6 and 7 show still another embodiment of the present invention. In this embodiment, the magnet 4 is fixedly provided at a position facing the concave portion 2, and a lever 10 for blocking the magnetic force of the magnet 4 is provided between the magnet 4 and the concave portion 2. The lever 10 is made of a magnetic material, and the position of the solid line for interrupting the magnetic force and the position of the broken line for releasing the magnetic force shown in FIG. When the lever 10 is at the broken line position, the magnetic force of the magnet 4 acts on the concave portion 2 to attract the binding device to the concave portion 2 to prevent scattering of the binding device, and when the lever 10 is at the solid line position, The magnetic force of the magnet 4 is cut off, and accordingly, the action of the magnetic force on the binding tool is cut off, so that the binding tool can be easily taken out.

FIGS. 8, 9 and 10 show still another embodiment of the present invention. FIG. 8 shows a state where the magnetic force of the magnet 11 is released and the magnetic force acts on the concave portion 2, and FIG. 2 shows a state in which the magnetic force is cut off. 8 and 9, a pair of magnetic members 12 is provided at a position facing the concave portion 2. Further, the magnet 11 is rotatably provided so that it can take the two positions shown in FIGS. FIG. 8 shows the magnet 11
, The line of magnetic force from the magnet 11 is
By the action of 2, the concave portion 2 is reached, and the binding tool is attracted to the concave portion 2. On the other hand, when the magnet 11 is at the position shown in FIG. 9, the magnetic force of the magnet 11 does not reach the recess 2 due to the action of the magnetic body 12, and the magnetic force is cut off. The rotation of the magnet 11 is performed by operating the knob 13 shown in FIG. In this embodiment, a copying machine has been described as an example, but the scope of the present invention is not limited to this, and the present invention is also applicable to an image forming apparatus such as a printer or a facsimile machine.

[0011]

As described above, according to the present invention, scattering of small items such as binding devices can be prevented, and small items can be easily taken out.
