Abstract

PURPOSE:To prevent a situation that a copying machine main body is supported at three points and gets unstable when a caster to which an adjuster is not disposed adjacently is separated from the floor surface because one of the casters is often separated from a floor surface in the conventional image forming device supported by four casters and three adjusters. CONSTITUTION:The casters 3-a, 3-b and 3-d having the same height and the short caster 3-f and the adjusters 6-a, 6-b and 6-c are disposed on a main body bottom board 19. The paper ejection port 4 of the copying machine main body 1 and the entrance 5 of a sheet sorting device 2 are aligned by the casters 3-a and 3-b, and the adjuster 6-c is butted on the floor surface. Since the casters 3-a, 3-b and 3-d are longer than the caster 3-f, they are necessarily put on the floor, and the copying machine main body 1 is supported at four points by the adjusters and the caster 3-d.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus such as an electrophotographic copying machine, and more particularly, to a moving means for moving an image forming apparatus such as a copying machine to an installation place and an installation place. The present invention relates to a fixing unit that fixes the image forming apparatus so that it does not move firmly.

[0002]

2. Description of the Related Art Conventionally, an image forming apparatus such as a copying machine is moved to an installation location, and the image forming apparatus is fixed so as not to move firmly from the installation location (hereinafter, simply referred to as "fixing"). The method of 12 was taken. FIG. 11 is a front view of the copying machine main body, and FIG. 12 is a bottom view. In the figure, the copying machine main body 1 is installed by four casters 3-a, 3-b, 3-c, 3-d having rotatable wheels fixed near the corners of the lower surface of the rectangle of each device. Move up to. Further, the sheet sorting device 2 is moved by four casters 3-e so as to align the discharge port 4 side and the inlet 5 side of the copying machine body 1 at the installation location. Depending on the condition of the floor FL of the installation location, it is conceivable that the paper ejection port 4 of the copying machine body 1 and the entrance 5 of the sheet sorting device 2 are not aligned in the height direction. For example, when installed on a carpet, the copying machine body 1 is heavier than the weight of the sheet classifying apparatus 2, so that the paper discharge port 4 of the copying machine body 1 is lower than the entrance 5 of the sheet sorting apparatus 2 in the height direction. Become. In this state, the transfer paper cannot be transferred smoothly from the copying machine main body 1 to the sheet classifying device 2, and a jam of the sheet (transfer paper) may occur at this portion. Therefore, the height of the sheet discharge port 4 of the copying machine main body 1 is adjusted by the adjusters 6-a and 6-b provided on the lower surface of the copying machine main body 1 and which can be moved and adjusted in the height direction. Adjuster 6-a. As shown in FIG. 12, 6-b are provided at two positions on the paper discharge side of the copying machine main body 1.
The adjusters 6-a and 6-b not only adjust the height, but also serve to prevent the copying machine body 1 from moving from the installation position.

In recent years, in order to improve the user's ability to deal with jamming, it is common to use front loading so that each unit inside the copying machine main body 1 can be pulled out to the front side. In such an apparatus in which each unit is front-loaded, in a large apparatus such as a high-speed copying machine, the weight of the remaining apparatus main body is sufficiently heavier than the weight of the front-loaded unit. Therefore, even if the front loading cassette 7, the transport unit, and the fixing device (not shown) are all pulled out to the front side of the copying machine main body 1, there is no possibility that the copying machine main body 1 will fall to the front side. However, when the weight of the main body other than these units is not sufficiently heavy compared to the weight of the unit loaded with front loading such as a medium-speed copying machine, the front loading cassette 7, the transport unit and the fixing unit are all used in the copying machine. Since there is only one adjuster 6-a on the front side of the copying machine main body 1 when the copying machine main body 1 is pulled out to the front side, the copying machine main body 1 may fall forward and the user may be injured. Therefore, in the conventional apparatus, as shown in FIGS. 13 and 14, one adjuster 6-c is added to the front side (arrow A side) of the user of the copying machine main body 1 to shift the fulcrum of the copying machine main body 1. , A total of three adjusters 6-a, 6-b, 6-
A flat surface is formed by c, and these are adjusted 6-
By pressing a, 6-b and 6-c against the floor FL of the installation location, the copying machine main body 1 is prevented from falling.

[0004]

However, in FIGS. 13 and 14, the four casters 3-a, 3-b, 3-c and 3-d provided in the copying machine main body 1 are different from each other. Dimensional accuracy and casters 3-a, 3-b, 3-c,
Due to the flatness of the bottom plate of the copying machine body 1 supporting the 3-d, it is possible to make all of the casters 3-a, 3-b, 3-c, 3-d contact the floor FL of the installation place. Have difficulty. Four casters 3-a, 3-b, 3-c, 3-d
Of these, one is often away from the floor FL. Also, the floor FL at the installation location is not a place having perfect flatness, and one caster may be separated from the floor FL because the floor FL has irregularities. For example, one caster 3-d shown in the lower right of FIG. 14 is in contact with the floor surface, and the remaining casters 3-d.
If any one of the casters a, 3-b, and 3-c is separated from the floor surface FL, lowering the three adjusters 6-a, 6-b, and 6-c onto the floor surface The copying machine body 1 is supported and stabilized by four adjusters 6-a, 6-b, 6-c and three casters 3-d. However, in the case where the casters 3-d not provided with the adjusters adjacent to each other are apart from the floor surface FL, the adjusters 6-a, 6-b, 6 at the three positions are set as described above.
Even if -c is lowered onto the floor surface FL, the copying machine body 1 is supported only at the three positions of the adjusters 6-a, 6-b, and 6-c.
Caster 3 without adjusters installed adjacent to it
Only -d leaves the floor FL. If the copier body 1 is supported at three points, the copier body 1 becomes unstable.
When the user pulls out the front loading cassette 7 and the transport unit, the fixing device, etc. to the user side (arrow A) for the jam processing, and when returning them to the apparatus main body side, the copying machine main body 1 Shakes, and as a result, the copying machine body 1 rattles. If the copying machine body 1 rattles, the following problems occur. (1) The positions of the discharge port of the copying machine body and the entrance of the sheet sorting device are misaligned, resulting in a jam. Further, the discharge port of the main body of the copying machine and the guide plate at the entrance of the sheet sorting apparatus are deformed or jammed. (2) During image formation, the main body of the copying machine may vibrate due to the acceleration of the movable member to cause an image defect. (3) The user feels uneasy and the reliability of the copying machine is suspected. (4) Jam and image defects occur due to deformation of parts and damage to those parts inside the main body of the copying machine, such as paper guide plate, optical mirror, etc. (5) When considering the reuse of the parts of the copying machine, if the parts are deformed, it is difficult to reuse them, and the resources cannot be effectively used. (6) Due to the deformation of the parts, it becomes difficult to disassemble the parts and serviceability deteriorates. As a result, the service takes longer and the service cost becomes higher.
