Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can be applied to office processing equipment such as a printer, a copier, a facsimile, or a complex machine thereof, which is equipped with an electric cord for connecting to a power source or other equipment. More specifically, the present invention relates to an electric cord attachment / holding structure for attaching and holding the end portion of the electric cord to the main body of the office equipment.

[0002]

2. Description of the Related Art Conventionally, in this type of office processing equipment, a structure for attaching and holding an electric cord has strength to ensure safety.

Among such electric cord mounting and holding structures, there are structures having the structures shown in FIGS. 4 and 5, for example. That is, the sheet metal attachment part 1 such as a sheet metal bracket is attached to the frame of the device body with screws. The attached portion 1 made of sheet metal is provided with a slit 1a and an engaging recess 1b intersecting with the slit 1a. On the other hand, the electric cord 2 is provided with a mounting portion 2a at its end. An annular groove 2b is provided on the outer periphery of the mounting portion 2a, and the annular groove 2b is formed.
The engaging convex portion 2c is provided on one side by sandwiching.

Then, the both edges of the slit 1a are inserted into the annular groove 2b, and the mounting portion 2a is fitted into the slit 1a. At this time, the engaging convex portion 2c is inserted into the engaging concave portion 1b and hooked. . Thus, after attaching the end of the electric cord 2 to the device body in this way, the outer cover 4 is covered on the frame 3 of the device body.

[0005]

However, in such a conventional electric cord attaching and holding structure, the attached portion 1 made of sheet metal is attached.
The engaging protrusion 2c of the mounting portion 2a is easily disengaged from the engaging concave portion 1b, and there is a problem that the attachment of the electric cord 2 to the sheet metal attached portion 1 becomes unstable.

SUMMARY OF THE INVENTION An object of the present invention is to make it easy to assemble and make it difficult for the electric cord mounting portion to come off from the sheet metal mounting portion.

[0007]

Therefore, the present invention provides
An end portion of the electric cord 14 is provided by attaching a mounting portion 20 to an end portion of the electric cord 14, and fitting the mounting portion 20 to a sheet metal mounting portion such as a sheet metal bracket 19 provided on the frame 18 in the device body 10. In an electric cord attachment holding structure for an office equipment that attaches to the device body 10, the attachment part 2 fitted to the sheet metal attachment part is attached to the outer cover 21 of the device body 10 that covers the frame 18.
It is characterized in that a pressing portion 21a for preventing the deviation of 0 is provided.

[0008]

According to the present invention, the mounting portion 20 at the end of the electric cord 14 is fitted to the sheet metal mounting portion provided on the frame 18 of the equipment body 10, and then the outer cover 21 is put on the frame 18 to hold it. The detachment of the attachment portion 20 is prevented by the portion 21a, and the end portion of the electric cord 14 is attached to the device body 10.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 is an external perspective view of the entire copying machine including the electric cord mounting and holding structure according to the embodiment of the present invention.

When recording is performed using this copying machine, the document pressing cover 11 on the apparatus body 10 is opened, the document is placed on a contact glass (not shown) and set, and then the document pressing cover 11 is closed again. Press the document and press the button on the operation display unit 12. Then, while the image on the original is read, the read image is formed on the photoconductor by repeating the electrophotographic process such as charging, writing, developing, transferring, and cleaning, and the image is formed on the sheet fed out from the paper feed cassette 13. The read image on the photoconductor is transferred and recorded. Then, the recorded sheet is conveyed and discharged onto a sheet discharge tray (not shown).

By the way, this copying machine is provided with a power cord (electric cord) 14 connected to a power source as shown in the drawing. The attachment holding structure for the power cord 14 is configured as shown in detail in FIGS. 1 and 2.

Reference numeral 18 in FIG. 1 is a frame of the device body 10. The frame 18 is made of a flat plate made of metal.

A bracket 19 is provided at the end of the frame 18. The bracket 19 is formed by bending a sheet metal into an L-shape when viewed from the side, and as shown in FIG. 2, a vertical slit 19b is provided substantially in the middle of the vertical portion 19a. Then, as shown in FIG. 1, the vertical portion 1
The horizontal portion 19c is placed on the frame 18 of the device body 10 with 9a facing outward and fixed by a screw (not shown).

The end of the power cord 14 is attached to the bracket 19. A mounting portion 20 is provided at the end of the power cord 14. The mounting portion 20 is made of resin and is made integrally with the power cord 14, and a groove portion 20a is formed on the outer periphery thereof.
b and the inner wall portion 20c are formed. The outer wall portion 20b and the inner wall portion 20c have a quadrangular brim shape, and make the outer wall portion 20b larger than the inner wall portion 20c.

Then, the groove 2 is formed in the slit 19b.
0a is inserted and the slit 1 is formed in the groove 20a.
Inserting the edges on both sides of 9a, the mounting portion 20 is fitted to the bracket 19. Then, the inner wall portion 20c is placed on the horizontal portion 19c, and the upper end of the inner wall portion 20c is projected slightly upward from the vertical portion 19a of the bracket 19, while the outer wall portion 20b is arranged outside the vertical portion 19a. Become.

Then, the frame 1 of the device body 10
An outer cover 21 is put on the upper part 8. Its exterior cover 2
1 is made of coated sheet metal, vinyl chloride steel plate, resin, or the like, and as shown in FIG. 2, a cutout window 21a is provided at the lower edge portion, and the cutout window 21a is bent inward at a right angle inward from the center of the upper edge of the cutout window 21a. To form the pressing portion 21b. Then, when the outer cover 21 is put on as shown in FIG.
While pressing the inner wall portion 20c to prevent the attachment portion 20 from coming off from the bracket 19, the cutout window 21a is closed by the outer wall portion 20b.

In the illustrated embodiment described above, the bracket 19 is provided separately from the frame 18 and fixed to the frame 18. However, although not shown, the bracket may be formed integrally with the frame 18 and cut and raised from the frame 18.

[0018]

Therefore, according to the present invention, the mounting portion at the end of the electric cord is fitted to the sheet metal mounting portion provided on the frame of the equipment body, and then the outer cover is covered on the frame and the pressing portion is used. Since the detachment of the attachment portion is prevented and the end portion of the electric cord is attached to the main body of the apparatus, the assembly can be simplified, the attachment of the electric cord can be made difficult to come off, and the safety can be improved.
