[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a copying machine, a facsimile machine, a multifunction printer, etc., having an image reading section for reading image information from a document and an image forming section for forming an image and recording the image on a recording medium. The present invention relates to an image processing device.

2. Description of the Related Art As an image processing apparatus having both an image reading section and an image forming section, a copying machine, a facsimile apparatus, a multifunction printer combining them, and the like are known. In particular, when the image forming method is an electrophotographic method, the process cartridge in which a photosensitive drum as an image bearing member, a developing unit, a toner container, a charging unit, and the like are integrated so as to be detachable from the main body can be used. Those with improved maintainability are generally widely known.

In the case of an electrophotographic apparatus using such a process cartridge, since the process cartridge is relatively large, the opening / closing unit of the apparatus main body for attaching and detaching the process cartridge is also large. On the other hand, since the device is often installed on a desk and used, there are many users who want to reduce the size of the device. From such a viewpoint, there has been known an image reading unit which is made as small as possible and the image reading unit and an operation panel are integrally formed in an opening / closing unit.

The image reading section includes a contact type image sensor as reading means for reading image information, a stepping motor as driving means for driving a conveying means for conveying a document, and an operation panel. It has electrical units such as necessary circuit boards. These electric units are connected to an electric control circuit board of the apparatus main body by electric signal lines.

Further, from the viewpoint of user operability, the operation panel is arranged on the front of the apparatus, and the opening / closing unit can be rotated downward and downward so that the process cartridge can be attached and detached from the front of the apparatus. are doing.

[0006]

However, in the above-mentioned conventional configuration, the electric signal line is entangled and moved by the opening / closing operation of the opening / closing unit, so that the electric signal line is mechanically damaged. Becomes Therefore, it is necessary to regulate the behavior of the electric signal lines particularly on the opening / closing unit side and the apparatus main body side. For this reason, a dedicated cover member for regulating the electric signal line is often provided. The cover member plays an important role in protecting the electric signal lines exposed when the opening / closing unit is opened from the influence of static electricity coming from outside.

On the other hand, a certain space is required for wiring a plurality of electric signal lines. In particular, the regulation of the electric signal lines on the opening / closing unit side requires a space for securely fixing the cover member, and how the processing is performed in a space-saving manner greatly affects the miniaturization of the apparatus.

However, there is no particular space in the vicinity of the pivot point of the opening / closing unit, and it is extremely difficult to achieve both a strong structure for supporting the opening / closing unit and securing a wiring space for electric signal lines. Further, in addition to the cost of the cover member itself being increased, the shape of the component may be complicated by forming the cover member into a shape that can be fixed efficiently, and the component cost may increase.

Therefore, the present invention suppresses an increase in cost by eliminating the need for a dedicated cover member for an electric signal line connected to the electric unit provided in the switching unit.
Another object of the present invention is to provide a miniaturized image processing apparatus that can protect an external static electricity or the like, efficiently process electric signal lines in a space-saving manner, and can support a heavy open / close unit.
