2. Description of the Related Art A reading unit of an image forming apparatus such as a copying machine maintains an attitude equivalent to that of a unit adjusted alone so that an image of a document can be read accurately. It is necessary to attach to the image forming apparatus main body without causing distortion or deformation.
Therefore, the structural member of the image forming apparatus main body needs to have a structure capable of securing the levelness of the positioning of the reading unit. However, to the knowledge of the present inventors, there was no structure that was satisfactory.

Accordingly, an object of the present invention is to provide a structure of an image forming apparatus capable of easily securing the flatness of a reading unit.

[0004]

According to a first aspect of the present invention, there is provided a structure of an image forming apparatus for achieving the above object.
It has a pair of left and right support members that support the reading unit, both ends of one support member are fixed to a pair of front and rear structural members, and one end of the other support member is one structural member of another pair of front and rear structural members And is rotatably supported in a vertical direction.

According to a second aspect of the present invention, in order to achieve the above object, in the structure of the image forming apparatus according to the first aspect, the other support member is rotatably mounted in a vertical direction. A rotating member which is rotatably supported so as to be able to abut on the lower surface of the other supporting member.

According to a third aspect of the present invention, there is provided an image forming apparatus according to the first or second aspect of the present invention, wherein the frame-like member having a projection having a sufficient flatness on a lower surface side is provided. And wherein the projections of the frame-shaped member are fixed at three points with the three support members supporting the support member.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an external perspective view (A) and an exploded perspective view (B) of an image forming apparatus showing a first embodiment of a structure of the image forming apparatus according to the present invention, and FIG. 2 is an enlarged side view of a main part. . In the illustrated image forming apparatus, a reading unit 101 is disposed above a main body 100 of the apparatus, and a recording sheet printed on a sheet discharging unit 102 below the reading unit 101 is discharged. The image forming apparatus supports the reading unit 1 at three points, that is, two points on the right side and one point on the left side when viewed from the front, in order to improve the ease of taking out the discharged recording sheet.

The apparatus main body 100 is composed of a number of structural members 1 to 7, and the reading unit 101 has legs 101a to 101a.
The support members 11, 1 are positioned in the vertical direction at 101d.
Place it on 2 The support member 11 is located near both ends (11 in the figure).
a, 11b) are fixed to the structural members 1, 2 with screws or the like. On the other hand, the other support member 12 has one end rotatably supported by the structural member 3 as shown in FIG.

In this embodiment, in order to mount the reading unit 101 on the apparatus main body 100, as shown by an arrow x in the figure, the support member 12 is mounted around a shaft 3a which is a fulcrum of the support member 12 with respect to the structural member 3. The reading unit 101 is rotated, thereby adjusting the vertical position of the other end of the support member 12, thereby setting the four points (foot 101) on the installation surface of the reading unit 101.
After confirming that the flatness of (a) to (101d) is ensured, the fixing portion 12a of the support member 12 is fixed to the structural member 3 with screws or the like. By rotating one of the two support members 11 and 12, the flatness of the reading unit 101 can be easily ensured.

FIG. 3 is an enlarged side view of a main part showing a second embodiment of the structure of the image forming apparatus according to the present invention. This embodiment has substantially the same structure as that of the first embodiment, except that a butterfly wing-shaped member 13 is rotatably supported on a structural member 3 around a shaft 3b. After the adjustment of the support member 12 in the first embodiment, the member 13 is rotated around the shaft 3b so that one edge thereof abuts against the support member 12, and the fixing portion 13a
Is fixed to the structural material 3 with screws or the like. With this configuration, it is possible to suppress displacement, deformation, and the like of the support member 12 due to the weight of the reading unit 101.

FIG. 4 is an exploded perspective view showing a third embodiment of the structure of the image forming apparatus according to the present invention, and FIG. 5 is an enlarged side view of a main part. In the present embodiment, the frame-shaped member 20 is divided into the structural members 1, 2, 3, and 3 points (arrows 20a, 20b, 20c in the figure).
(Projections indicated by). 4 of the frame member 20
The tips of the point projections 20a to 20d
The flatness required for 01 is previously secured. That is, since no load other than its own weight is applied to the frame-shaped member 20, the protrusion 2
If 0a to 20c are fixed, protrusion 20d
The required flatness is secured, including the tip of.

In this state, the flatness of the mounting surface of the reading unit 101 can be ensured by adjusting and fixing the support member 12 in accordance with the projection 20d of the frame-shaped member 20 (FIG. 6). Further, the frame member 20 is not fixed at the adjustment position 20d of the support member 12, and the reading unit 1
01 is separated. Therefore, the frame-shaped member 20 is not subjected to a load such as unit weight or the like, and is not deformed, so that the flatness of the tips of the projections 20a to 20d is always kept constant.

Therefore, by adjusting the support member 12 in accordance with the frame member 20, the flatness of the mounting portion of the reading unit 101 can be ensured. Also, the reading unit 10
Even if the fixing position of the support member 12 goes out of order for some reason after mounting, it can be easily corrected and readjusted.

[0014]

According to the structure of the image forming apparatus according to the first aspect of the present invention, as described above, the reading unit is supported by rotatably supporting one of the two support members. There is an effect that the flatness of can be easily secured.

As described above, the structure of the image forming apparatus according to the second aspect is obtained by adding a rotatable member capable of coming into contact with the supporting member from the lower surface to the apparatus according to the first aspect. In addition to the above-mentioned common effects, there is an effect that displacement due to a load after assembling the rotatable support member can be prevented.

According to a third aspect of the present invention, there is provided an image forming apparatus comprising:
As described above, the frame-shaped member which is fixed to the support member of the reading unit at three points, and which is separate from the reading unit and which can be held by the apparatus main body in a state where flatness is secured. Therefore, in addition to the above-mentioned common effects, there is an effect that the displacement of the rotatable support member after assembly can be easily corrected.
