Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is an overall perspective view of an image forming apparatus 1 in the present embodiment. Reference numeral 2 denotes a document cover integrally provided with an automatic document feeder, 3 a document glass (contact glass), 4 a main body tray, 5 a power display unit, 6 a power key, and 7 an operation unit. , 8 is an upper tray discharge display lamp, 9 is a main body upper tray, 10 is a duplex unit, 11 is a front cover as an opening / closing member, 12a, 12b, 12c and 12d are paper feed trays, and 13 is an apparatus. Each body is shown.

The front cover 11 can be opened outward with the lower end side as a fulcrum. That is, it can be opened and closed in the direction of arrow A.
FIG. 2 shows a state in which the front cover 11 is opened to the outside. The front cover 11 is connected to the apparatus main body 13 via a hinge portion 14 and is rotatably supported. Reference numeral 15 indicates a rotation fulcrum (rotation center line).
By opening the front cover 11, operations (toner replacement, transfer paper removal operation, etc.) in the apparatus main body 13 can be performed.
A plurality of longitudinal ribs 11a and lateral ribs 11b are formed inside the front cover 11 for the purpose of improving strength. In FIG. 2, the thickness of the front cover 11 is omitted, and the ribs 11a and 11b are indicated by two-dot chain lines.
Inside the front cover 11, an apparatus operation method explanation sheet 16 is installed so as to cover the ribs 11a and 11b.
The apparatus operation method explanation sheet 16 is detachably installed by engaging a peripheral edge with a hook (not shown), for example.

As shown in FIG. 3, the apparatus operation method explanation sheet 16 has a sheet main body portion 16a on which a description of the operation method and the like is printed using characters and patterns, and a receiving portion 16b that receives dust such as toner.
The apparatus operation method explanation sheet 16 is made of artificial paper or synthetic paper and has a predetermined shape retaining property.
When the toner is exchanged, the toner may fall on the rotation fulcrum 15 side (inner side direction) of the front cover (door portion) 11, and cleaning becomes difficult if the toner falls on the portion partitioned by the ribs. For example, when the toner cartridge is replaced, if the replacement operation is not appropriate, the toner tends to fall.
In the present embodiment, in order to solve this problem, a receiving portion 16b is provided so as to cover the upper surface of the rib on the rotation fulcrum 15 side of the front cover 11, which is a portion where toner is likely to fall.

The dropped toner T is received by the receiving portion 16b and does not reach the part partitioned by the ribs. Since the receiving portion 16b is a flat surface formed integrally with the sheet main body portion 16a, the toner T can be easily cleaned. Therefore, a plurality of functions can be obtained from the integrally formed apparatus operation method explanation sheet 16.
In the device operation method explanation sheet 16, only the sheet main body portion 16a has a function of transmitting the explanation contents to the user, and the receiving portion 16b does not have the function. Therefore, it is necessary to remove the receiving portion 16b from the description content portion (sheet main body portion 16a) in terms of area. From this viewpoint, providing the receiving portion 16b in the vicinity of the rotation fulcrum 15 side has a great effect.
In the present embodiment, the shape of the receiving portion 16b is rectangular. However, the shape is not limited to this, and the receiving portion 16b can be appropriately set as long as it has a function of receiving dust such as toner (the following other embodiments). The same).

Next, a second embodiment will be described based on FIG. Note that the same parts as those of the first embodiment are denoted by the same reference numerals, and unless otherwise specified, the description of the configuration and functions already described is omitted, and only the main parts will be described (the same applies to the other embodiments below).
Since this type of device operation method explanation sheet is a printed matter, in general, there are many structures that perform multi-color or single-color printing on the surface (skin surface) of light color (light gray, white, etc.) to perform its function. In many cases, dirt is noticeable due to the dropped toner. In addition, the remaining toner may be noticeable even after cleaning.
The object of the present embodiment is to make the stains caused by such toner and the like inconspicuous.

The receiving portion 16b in the present embodiment is provided as a uniform coloring range, and the entire surface is colored black. In FIG. 4, it is indicated by hatching. Therefore, even if the toner falls and is not cleaned, the presence of the toner becomes inconspicuous.
The coloring is not limited to black, and any color that can make the presence of dust such as toner inconspicuous is acceptable. Further, it is not necessary to color the entire surface of the receiving portion 16b. For example, the presence of toner may be camouflaged by displaying dots in a dark color such as black. Further, the receiving portion 16b may be colored to make the presence of toner inconspicuous.

A third embodiment will be described with reference to FIG.
Since the toners dropped on the receiving portion 16b are not charged, they cannot be electrically or mechanically held on the receiving portion 16b. Therefore, before cleaning, for example, the toner may be scattered due to wind pressure or the like during the opening / closing operation of the front cover 11 and fall to a part not covered with the apparatus operation method explanation sheet 16.
The purpose of this embodiment is to hold dust such as toner in the receiving portion 16b. As shown in FIG. 5, an adhesive sheet 17 as a dust holding sheet having an area covering almost the entire region is attached to the surface of the receiving portion 16 b.
The pressure-sensitive adhesive sheet 17 is a resin-made transparent sheet having a sticky surface, and is attached to the surface of the receiving portion 16b with the back surface. A sheet having a sticky surface may be attached with an adhesive, but in the present embodiment, as the pressure sensitive adhesive sheet 17, a sheet having both stickies is used.

The dropped toners are held on the upper surface of the receiving portion 16b, that is, the surface of the adhesive sheet 17 due to adhesiveness, and cannot move (scatter). A peeling piece 17a for peeling off is formed at one end of the pressure-sensitive adhesive sheet 17, and when the toner is accumulated, it is removed together with the toner and discarded as appropriate (for example, during maintenance).
Since the pressure-sensitive adhesive sheet 17 has transparency, it does not have a camouflage function with respect to toner or the like, but if the receiving portion 16b is colored or patterned, it can be made inconspicuous, and dropped toner or the like Even if it is held, deterioration in appearance quality can be suppressed.
For example, polypropylene, polyamide, or polycarbonate can be used as the material of the pressure-sensitive adhesive sheet 17.
In the configuration in which only one pressure-sensitive adhesive sheet 17 is applied, it takes time to apply a new pressure-sensitive adhesive sheet 17 when the adhesive sheet 17 is peeled off. However, as shown in FIG. If the adhesive sheet 17 soiled with toners is peeled off, a new adhesive surface appears at the same time.
That is, the toner removal operation by peeling off the adhesive sheet 17 can be repeated without preparing a new adhesive sheet 17 (fourth embodiment).

  In each of the above embodiments, the front cover 11 is exemplified as the opening / closing member (door portion). However, the present invention is not limited to this.

A fifth embodiment will be described with reference to FIGS.
As shown in FIG. 7, on the front surface of the apparatus main body (apparatus housing) 21 of the image forming apparatus 20,
A front cover 22 is provided as an opening / closing member that can be opened and closed during maintenance and jam processing. A lower end portion of the front cover 22 is rotatably supported by a base portion 23 as a front lower flat portion space of the apparatus main body 21 via a hinge member.
At the time of maintenance for not-shown photosensitive drum unit or developing unit replacement, the front cover 22 is opened, the pressing of the photosensitive unit face plate 24 is released, and the photosensitive drum unit and the like are pulled out to the front side. When such operations are performed, toner or the like spills and falls inside the opened front cover 22 and accumulates in the corners of the ribs 22a and 22b inside the front cover.

In order to prevent this, as shown in FIG. 8, an antifouling sheet 25 as an antifouling member having a smooth surface is attached to the inner side (inner side) of the front cover 22 as in the above embodiment. Since it has a smooth surface, it becomes easy to clean.
The image forming apparatus 20 shown in FIG. 7 does not show a dedicated structure as an implementation target of the antifouling sheet 25, and can also be implemented by the above-described apparatus operation method explanation sheet 16, and the image forming apparatus 1 shown in FIG. In this case, the antifouling sheet 25 can be implemented.

The antifouling sheet 25 has a shape that covers a part or substantially the entire inner surface of the front cover 22 and extends to the base portion 23 of the apparatus main body 21. One end portion 25a extending to the base portion 23 is fixed to the base portion 23 with a screw 26 at one or more (here, two) positions. The inner surface of the front cover 22 is also fixed with a plurality of screws 27.
Since the one end portion 25a of the antifouling sheet 25 extends beyond the rotation fulcrum side of the front cover 22 and the base portion 23 in the apparatus main body 21, toner and the like are removed from the gap between the base portion 23 and the front cover 22 from the apparatus main body. 21 is prevented from falling outside. Further, as described above, since the one end portion 25a of the antifouling sheet 25 is fixed to the base portion 23, the one end portion 25a can be prevented from floating from the base portion 23, and the base portion 23 and the front cover 22 can be prevented from floating. It is possible to reliably prevent the toner or the like from dropping out of the apparatus main body 21 from the gap.
In the case where the above problem does not occur without the one end portion 25a floating from the base portion 23, it is not always necessary to fix the one end portion 25a to the base portion 23.

The antifouling sheet 25 has a bent portion 25b for obtaining a hinge function associated with the opening / closing operation of the front cover 22 in the vicinity of one end portion 25a thereof.
As shown in FIG. 9, the bent portion 25 b is set to be thinner than other portions so as to bend easily when the front cover 1 is opened and closed. As a material, nylon resin having excellent bending performance is desirable. However, as long as the material has high flexibility and a smooth surface, there is no problem even if other materials are used instead of the resin material.
Also, an operation sheet describing a jam processing method that is often attached to the inner side of the front cover 22 by using a transparent material for the antifouling sheet 25 (the above-described apparatus operation method explanation sheet having a toner contamination preventing function). Instead, a conventional apparatus operation method explanation sheet) can be inserted under the antifouling sheet 25, and the operation sheet can be seen without being stained.
As the material of the antifouling sheet 25, a sheet material such as a polyester film excellent in durability against repeated bending is desirable. Furthermore, if the thing about 25 micrometers-188 micrometers in thickness is used, the function of the bending part 25b can be acquired, without creating a thin part (bending part 25b). Thereby, cost reduction and weight reduction can be achieved at the same time.
Further, if a plurality of such thin antifouling sheets 25 are installed in a stacked manner, it is possible to save the trouble of cleaning by discarding them one by one when the dirt cannot be removed.

10 and 11 show a sixth embodiment.
In the fifth embodiment, the one end portion 25a of the antifouling sheet 25 is fixed to the base portion 23 with the screw 26, but this embodiment is characterized in that it is detachably fixed (held).
As shown in FIG. 10A, a shaft-shaped fixing member (holding member) 28 is fixed to the base portion 23 instead of the screw 26. The fixing member 28 has a head portion (a retaining portion) 28 a whose diameter gradually increases downward (fixed end side) and a locking portion 28 b that also serves as a fixing portion to the base portion 23.
As shown in FIG. 10B, a holding hole 25 c in which a circular part protrudes inward is formed in one end portion 25 a of the antifouling sheet 25. The maximum diameter B of the head portion 28a, the diameter A of the locking portion 28b, and the minimum diameter C of the holding hole 25c are set so as to satisfy B>C> A, and the one end portion 25a of the antifouling sheet 25 is pushed in. Thus, it can be easily locked, and can be easily removed by applying a certain amount of force. That is, it can be attached and detached by a one-touch operation. Thereby, the exchangeability of the antifouling sheet 25 can be improved.

As shown in FIG. 11A, a fixing member 29 having a head portion (a retaining portion) 29a whose diameter gradually increases downward, a locking portion 29b, and a fixing portion 29c to the base portion 23. As shown in FIG. 11B, the holding hole formed in the one end portion 25a of the antifouling sheet 25 may have a shape having a portion protruding inward at a circular facing position.
In the present embodiment, the one end portion 25a of the antifouling sheet 25 is locked and fixed (held) to the fixing member. However, the base portion 23 is provided with an insertion portion into which the one end portion 25a can be inserted. It may be prevented from floating by inserting. Since substantially the entire antifouling sheet 25 is fixed or held on the front cover 22, the lifting of the one end 25a can be suppressed by simply inserting it.
Further, the description content of the device operation method explanation sheet may be displayed on the antifouling sheet 25 itself so as to also function as the device operation method explanation sheet.
