Description

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 a copying machine, a printer, a facsimile and the like, and more particularly to an improved caster for moving the image forming apparatus.

[0002]

2. Description of the Related Art In a floor-mounted image forming apparatus, particularly a relatively large-sized image forming apparatus, it is essential to provide a caster for movement in order to install the apparatus at a predetermined position. In addition, in order to prevent movement after installation and to secure a horizontal installation state irrespective of the flatness of the floor at the installation location, a fixing adjuster for fixing is commonly provided.

FIG. 1 is a perspective view showing an example of the above-described image forming apparatus. In the figure, reference numeral 1 denotes an apparatus main body, and 2 denotes a caster for moving the apparatus, which is provided at each of four corners on the bottom surface of the apparatus main body 1. In the figure, reference numeral 3 denotes an adjuster for fixing the position of the apparatus main body 1, which is provided at the four corners on the bottom surface of the apparatus main body 1 like the caster 2, and has a configuration in which the height can be adjusted by screws or the like. I have.

However, even with such a configuration,
Except in the case where the flatness of the installation place is extremely poor, fixing by the adjuster is not performed, and the installation is often performed as it is after the movement by the caster. In this case, one of the casters at the four corners may be slightly lifted up, which may cause a problem such as shaking of the device.
Further, to the knowledge of the inventors of the present application, no technique has been proposed for a moving caster of this type of image forming apparatus, which is configured to be adjustable or detachable in an installed state of the apparatus.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, an object of the present invention is to provide an image forming apparatus capable of finely adjusting a caster and stabilizing an installation state.

[0006] In most cases, there is not enough space on the back and side surfaces of the image forming apparatus as described above to perform various operations. Therefore, it is very difficult to perform the operation of attaching and detaching the casters.

It is another object of the present invention to provide an image forming apparatus with improved workability such as mounting and removing casters.

Another object of the present invention is to provide an image forming apparatus in which the number of adjusters is reduced and the cost is reduced by providing the function of an adjuster to a caster.
