Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a body frame for a copying machine that is easy to manufacture by unitizing each functional part of the copying machine and forming a welded structure.

Normally, in the body frame of a copying machine, guide rollers, guide members, attachment means for various functional parts, etc. are directly attached, so complicated post-processing must be performed on the constituent plates of the body frame. For this reason, conventionally, after performing the necessary post-processing on the structural plates that have been coated with anti-rust coating, the structural plates are assembled using setscrews or the like to complete the fuselage frame. However, with this type of fuselage frame structure, it becomes necessary to apply anti-corrosion treatment to each component plate separately, which complicates the assembly work of the component plates and introduces problems such as subsequent loosening between the component plates. There are some inconveniences.

This invention eliminates the need for complex post-processing of the machine frame by completely integrating the functional parts of the copying machine.This allows for one-shot painting, saves labor in assembly work, and eliminates the need for complex post-processing of the machine frame. This project proposes an aircraft frame with a welded structure that does not distort.

The details of the present invention will be explained below with reference to the drawings.

FIG. 1 shows the entire fuselage frame according to the present invention. On the bottom wall 1 made in the shape of a rectangular shallow dish, there are
The lower ends of the pair of side walls 2 and 3, which are made to have the same size and shape, are welded together. Further, at a position near the top of the side walls 2 and 3, there is a mounting table 4 made in the shape of a rectangular frame.
and a pair of auxiliary frames 5, 6 with a “U”-shaped cross section.
The mounting table 4 and the auxiliary frames 5 and 6 ensure the rigidity of the fuselage frame. Mounting windows 7 are provided on the surfaces of the side walls 2 and 3 through which functional units, details of which will be described later, can be inserted from the outside.
is formed.

On the other hand, a pair of end walls 8, 9 are welded to both ends of the side walls 2, 3, and rectangular insertion holes 10, 11 are formed in the lower portions of these end walls 8, 9.
These insertion holes 10 and 11 are used as holes into which functional units to be described later are inserted.

Prior to assembly, the above-mentioned fuselage frame is
The screw holes 12, 13, 14, 15, 16, 17 are opened, and the guide rails 18, 19 and the support rail 20 are installed in the mounting window 7 for use. That is, as shown in FIG. 2, the mounting window 7 has a photosensitive drum A, a developing device unit B, a separating
A transport unit C, a fixing unit D, and a cleaning unit E are inserted, the photosensitive drum A is mounted on a stay 21 screwed into a screw hole 12, and a developing unit B and a fixing unit D are installed on the guide rails 18, 19. Each is supported by
Further, the separation/conveyance unit C has a screw hole 13.
The cleaning unit E is assembled to the machine frame by a fixing plate 22 screwed to the body frame, and the cleaning unit E is suspended on the support rail 20.

Further, an optical unit F is placed on the mounting table 4, and this optical unit F is assembled to the mounting table 4 by a set screw 23 screwed into the screw hole 14. The toner supply unit G supported by the auxiliary frames 5 and 6 is connected to the auxiliary frames 5 and 6 by a set screw 24 screwed into the screw hole 15.
It is fixed at 6.

Paper feed tray unit H that can accommodate copy paper cassettes
is inserted into the body frame through the insertion hole 10 of the end wall 8, and is fixed to the end wall 8 by a set screw 25 inserted into the screw hole 16. Then, the paper ejection row unit I is inserted through the insertion hole 11 of the end wall 9, and this paper ejection roller unit I is fixed to the machine frame by a set screw 26 screwed into the screw hole 17. .

Since the fuselage frame of the present invention has the structure described above, it is not only possible to apply anti-rust coating to the fuselage frame all at once, but also to assemble each functional unit of a copying machine with simple processing after painting. Can be attached. Therefore, it is no longer necessary to perform separate painting and assemble component plates with screws, which were conventionally required to complete the fuselage frame, and the problem of subsequent distortion of the fuselage frame can be solved. Of course, it goes without saying that these advantages are the result not only of the functional parts being made into units, but also of the rational arrangement of the various structural parts of the fuselage frame.
