Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a reinforcing structure used in an image forming apparatus such as a copying machine or a printer, and particularly in a large image forming apparatus.

(Prior Art) The frame of the copying machine is shown in FIG.
As shown in the conventional example in FIG.
11, the photoconductor drum 12, the fixing device 13, the developing device 14, etc., support the components of the copying machine by the side plates 15 and 16, and the side plates 15 and 16 are L-shaped.
The bottom plate 17 has a structure in which a bottom portion processed into a V shape is supported.

Therefore, the bottom plate 17 receives the entire weight of the machine,
Therefore, in order to obtain rigidity to the bottom plate 17, the bottom plate is thickened or a reinforcing plate is fixed by welding or the like.

However, in order to give the bottom plate 17 rigidity, making the bottom plate thicker increases the weight of the bottom plate 17, and thus the weight of the copying machine. Therefore, it is preferable to use a reinforcing material because it is simple.

On the other hand, in a conventional copying machine, a foot such as a handle for carrying the machine, a caster, or a columnar elastic body for preventing slippage, which is different from the reinforcing material, is provided on the bottom plate of the lower surface of the machine.

Therefore, as shown in FIGS. 6 (a) and 6 (b), a reinforcing material 23 is attached to the lower surface of the bottom plate 22 of the copying machine 21, and the reinforcing material 23
There is one in which the foot 24 is fixed (Japanese Utility Model Publication No. 57-133040).

(Problems to be solved by the present invention) By the way, the above-mentioned prior art aims to secure a gap between the floor on which the copying machine 21 is placed and the lower surface of the copying machine 21 to facilitate the transportation of the machine. If the weight of the main body of the apparatus further increases, for example, if the main body itself is large or optional equipment is additionally attached, the reinforcing material 23
There is a drawback that the bottom plate 22 of the cut 25 of the reinforcing material 23 is deformed by being loaded.

The present invention has been made with the above matters in mind, and the purpose thereof is to reduce the weight of the device itself,
It is intended to provide a reinforcing structure with increased strength.

(Means for Solving the Problems) According to the present invention, a bottom plate that holds various components and devices of the upper main body of the image forming apparatus, an upper reinforcement member fixed to an upper portion of the bottom plate, and a lower portion of the bottom plate are provided. An image is formed on the lower surface of the lower reinforcing material, which has a fixed lower reinforcing material, the upper reinforcing material and the lower reinforcing material are vertically crossed with the bottom plate sandwiched therebetween, and the upper and lower reinforcing materials are crossed with each other. There is provided a reinforcing structure for an image forming apparatus, which is provided with a foot for supporting the apparatus.

(Operation) According to the above configuration, the load of the apparatus main body is concentrated on the foot portion, but since the upper reinforcing material and the lower reinforcing material are arranged so as to intersect with that portion, the strength is increased. Furthermore, since the load is distributed to the upper and lower reinforcing members, it is possible to prevent uneven load.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view schematically showing a sheet metal frame for a copying machine according to an embodiment of the present invention. FIG. 2 is a side view of the embodiment of the present invention, and FIG. 3 is a front view of the same.

First, in FIG. 1 to FIG. 3, reference numeral 2 is a bottom plate for holding various parts and devices of the upper body of the copying machine, and the side plate is bent. Reference numeral 3 designates a pair of front and rear side plates (left and right directions in FIG. 2, and a direction perpendicular to the paper surface in FIG. 3), which are fixed on the bottom plate 2 by screwing or the like at precise positions. Four
.., 5 ... Reinforcement material, 4 is an upper reinforcement material fixed to the upper portion of the bottom plate 2, and 5 is a lower reinforcement material fixed to the lower portion of the bottom plate 2. The upper and lower reinforcing members 4 and 5 are U-shaped, and a bent portion is formed on the open side thereof, and the bent portion is fixed to the bottom plate 2. The upper reinforcing member 4 is fixed in a direction perpendicular to the side plate 3 with both ends penetrating the side plate 3, and the lower reinforcing member 5 is fixed to the lower surface of the bottom plate 2 in a direction orthogonal to the upper reinforcing member 4. still,
In the specific example, there are two upper reinforcing members 4 and three lower reinforcing members 5.
Fixed at equal intervals. Then, casters 6 are mounted on the lower surface of the lower reinforcing member 5 as legs for supporting the main body at a portion where the upper and lower reinforcing members 4 and 5 intersect with each other through the bottom plate 2.

That is, when the caster 6 is installed at a crossing position by devising the placement of the reinforcing material, the load applied to the caster 6 is distributed to the upper and lower reinforcing materials 4 and 5, and the bottom plate 2 is bent. To prevent.

Further, referring to FIG. 4, reference numeral 7 is a cover formed of resin or the like of the main body of the copying machine, and the lower end of the cover 7 is a lower reinforcing member 5.
The size is such that it does not project below the lower surface 51 of the. By this, for example, when the main body is transported by a hawk lift, which is a transportation means, when the operation means is inserted into the lower surface of the main body,
It always comes into contact with only the lower surface 51 of the lower reinforcing member 5. Therefore, it is possible to prevent the cover 7 from being damaged.

It should be noted that, in the above-described embodiment, a columnar elastic leg may be provided instead of the caster as the leg of the copying machine.

(Effect) As described above, according to the present invention, the upper reinforcing member and the lower reinforcing member are vertically crossed with the bottom plate interposed therebetween, and the image forming apparatus is provided on the lower surface of the lower reinforcing member where the upper and lower reinforcing members intersect. By providing the feet that support the image forming apparatus, even if the weight of the image forming apparatus itself becomes large, the rigidity is not increased by increasing the thickness of the bottom plate itself, and a reinforcing structure that sufficiently supports the image forming apparatus is provided. , It is possible to make up for the lack of strength.

・ Four legs and the bottom plate that supports the legs are fully loaded by the main body of the imaging device, but the position where the legs are provided is the lower surface of the lower reinforcing member where the upper and lower reinforcing members cross each other. Since this is the strongest part, the bottom plate is prevented from being deformed (flexed) even when supporting the foot.

Since the upper reinforcing member and the lower reinforcing member are provided above and below with the bottom plate sandwiched therebetween, the reinforcing member may be formed in a simple shape, for example, a cross section having a substantially "U", "L" or "□" shape. It is possible.

Since the upper reinforcing material and the lower reinforcing material are provided on the upper and lower sides with the bottom plate sandwiched therebetween, the reinforcing material is not overlapped on either the upper or lower side of the bottom plate, so that no dead space is generated.
