Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention is equipped with a dust-proof cover in the upper opening to insert a paper feed cassette of an image forming apparatus. The present invention relates to a sheet feeding cassette for an image forming apparatus that is set in a mouth.

[0002]

[Prior art]

  One image forming apparatus such as an electronic copying machine, a laser printer, a facsimile, or the like. It has a paper feed cassette insertion port for mounting a plurality of paper feed cassettes. Electronic copier 7, the paper feed cassette insertion slot 2 of the copying machine main body 1 has a paper feed cassette. Larger than the cross-sectional area of the paper feed cassette in the insertion direction to improve the detachability of the set 3 It is designed to have a large area. Further, the paper feed cassette 3 has an upper opening The dustproof cover 4 is provided on the sheet feeding section, but the dustproof cover 4 is used for a sheet feeding unit such as a sheet feeding roller. It is not possible to cover the entire upper opening of the paper feed cassette due to material coming in and out. This As a result, the paper feed cassette insertion slot 2 is in a state where the paper feed cassette 3 is actually attached. However, as can be seen from FIG. 7, the extra mouth is open.

[0003]

[Problems to be Solved by the Invention]

  As mentioned above, the paper cassette insertion slot is larger than the paper cassette cross-sectional area. Therefore, most of the sound generated inside the image forming apparatus is generated from the opening such as the insertion port. Is emitted to the outside. Further, at the insertion port, the paper is fed by a paper feed roller or the like. At this time, the sound of paper conveyance is emitted and emits noise.

[0004]   An object of the present invention is to eliminate the above-mentioned drawbacks in the conventional image forming apparatus. It

[0005]

[Means for Solving the Problems]

  According to the present invention, the above-mentioned problem is solved by the dustproof cover located on the insertion side of the paper feed cassette. A sound insulation member made of an elastic material is attached to one side so that it can rotate, and the paper cassette can be imaged. When set in the image forming apparatus, the sound insulation member is pressed against the outer cover of the image forming apparatus. It is solved by configuring so.

[0006]   Further, in order to solve the above-mentioned problems, the present invention attaches a sound absorbing material to the sound insulation member. Suggest that.

[0007]   Further, according to the present invention, in order to solve the above problems, the sound insulation member is attached to the dustproof cover. It is suggested that it be detachably attached.

[0008]   Further, in order to solve the above problems, the present invention provides that the sound insulation member includes the dustproof cover. It is proposed that they are integrally molded via a hinge part composed of a thin part.

[0009]

[Action]

  A dustproof cover is provided on the upper opening of the paper feed cassette that should be inserted into the image forming apparatus. Has been. An elastic member is attached to one side of the dust-proof cover located on the insertion side of the paper feed cassette. The sound insulation member is attached via the hinge part. Use a paper cassette as an image forming device When set, the sound insulation member is pressed against the outer cover of the image forming apparatus, Therefore, even if you set the paper cassette, the paper cassette insertion slot that is still open Is almost blocked, so that it is generated inside the image forming apparatus and is emitted to the outside from the insertion port. The noise made is reduced.

[0010]

【Example】

  The present invention will be described with reference to the copying machine and its paper feed cassette shown in FIGS. It

[0011]   In FIG. 1, the paper feed cassette 3 is inserted into the paper feed cassette insertion opening 2 of the copying machine main body 1. The paper feed cassette 3 is provided with a dustproof cover 4 that covers the upper opening of the paper feed cassette 3. ing. As shown in FIG. 2, the sound insulation member 5 made of an elastic material such as resin is used as a paper feed cassette. It is possible to swivel on one side of the dust cover 4 located on the insertion side of the door via the hinge portion 6. Noh is installed. As shown in FIG. 1, attach the paper feed cassette 3 to the copying machine main body 1. When attached, the sound insulation member 5 is pressed against the outer cover 1a of the copying machine main body 1 to feed the paper. The extra opening of the cassette insertion slot 2 is closed, so that the insertion slot 2 and the feeding slot are closed. The upper opening of the paper cassette 3 is almost completely shielded.

[0012]   Using a normal hinge for the hinge part 6, the sound insulation member 5 can be swung around the dustproof cover 4. Although it can be attached, the sound insulation member 5 and the dustproof cover 4 are shown in FIG. As described above, it is possible to integrally form the hinge portion 6'formed as a thin wall. is there.

[0013]   In FIG. 4, the lower surface of the sound insulation member 5 rotatably attached to the dustproof cover 4. The sound absorbing material 7 is attached to. This further reduces the noise leaking out of the machine. Can be reduced. The sound absorbing material 7 does not interfere with the side wall surface of the paper feed cassette 3. In this way, the sound insulating member 5 is attached to almost the entire lower surface.

[0014]   In the embodiment shown in FIG. 5, the sound insulation member 5 is attachable to and detachable from the dust cover 4 by the hinge 8. It is pivotally attached. Therefore, as shown in FIG. 6, the hinge 8 is provided on the side of the dust-proof cover 4. The removable member 9 is provided.

[0015]   In this way, the sound insulation member 5 is detachably attached to the dustproof cover 4 so that A paper cassette that is used each time by removing the sound member 5 from the used paper cassette It is only necessary to attach it to the dustproof cover of, and it is necessary to prepare as many sound insulation members as there are paper cassettes. The point is unnecessary.

[0016]

【The invention's effect】

  According to the first aspect of the present invention, it is possible to close the paper feed cassette insertion port of the image forming apparatus. Therefore, the noise radiated from the insertion port can be reduced.

[0017]   According to the structure of claim 2, the sound absorbing member attached to the lower surface of the sound insulation member prevents The noise emitted can be further reduced.

[0018]   According to the configuration of claim 3, the number of sound insulation members needs to be as many as necessary for use. Can reduce the financial burden of. In addition, the sound insulation member is simple when unnecessary. Can be stored in.

[0019]   With the structure of claim 4, no extra parts are required, the manufacturing is simple and the cost is low. Becomes cheaper.
