[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal member protection device and an image processing system using the same.

[0002]

2. Description of the Related Art Conventionally, there has been known an image processing system such as an image reading apparatus for reading a document image by moving a carriage equipped with a color image pickup means having a line sensor such as a CCD in parallel with a document surface. ing.

[0003] For example, in the case of a flat bed type image reading apparatus, a platen made of a transparent plate such as glass for placing a document is provided on the upper surface of a box-shaped casing. A carriage that is moved by a driving device in parallel with the document table is provided. The carriage is provided with a light source and a color imaging unit. Irradiation light from the light source is reflected on the surface of the document on the document table, and is condensed on a color image pickup means by a condenser lens.

In the image reading apparatus as described above, when the read image data is finally printed out, the image is displayed on a monitor by using a processing device such as a personal computer, and a desired image is selected by a printer or the like. And prints it out on a print medium such as printing paper.

[0005]

When performing an image printing process using a personal computer, a user performs a command input operation specified by an operation system, and a print processing application program and a printer driver are stored therein. For example, it is necessary to take the data from a storage device such as a magnetic disk into the internal memory of the personal computer and make it executable.

However, there is a problem that it takes a long time to input a command or to take in a print processing application program and a printer driver, and it takes a long time to start up. In addition, there are many problems to be solved in order to make full use of a personal computer. For example, there are a large number of users who cannot use a computer even if they have a personal computer.These users print out an image read by an image reading device. Even if an attempt is made to install the software, there is a possibility that the installation itself is difficult or that a command input method cannot be understood.

Therefore, an image reading unit that converts an image of a document into an electric signal and reads the image, and an image printing unit that prints the image on a print medium such as paper based on the image data read by the image reading unit are provided. An image processing apparatus that prints an image based on image data read without connecting to a personal computer can be considered. In such an image processing apparatus, it is a general configuration that the image reading unit and the image printing unit have a two-story structure, the image reading unit is arranged in the upper stage, and the image printing unit is arranged in the lower stage. Further, from the viewpoint of a mounting space, a control unit that controls the image reading unit and the image printing unit, and a power supply unit that supplies power to the image reading unit and the image printing unit are arranged at the lower stage together with the image printing unit.

In the image processing apparatus having the above-described structure, a metal member forming a frame of the housing is provided in a housing for accommodating the image reading section, the image printing section, the control means, and the power supply section, thereby improving the strength of the apparatus.

However, when a metal member is provided in the housing, a wiring cable for electrically connecting the image reading unit, the image printing unit, the control unit and the power supply unit, and a power supply cable for electrically connecting the power supply unit and the power supply source are provided. It may be difficult to manage cables such as cables. Therefore, it is conceivable to form a closing hole or a notch for passing the above-mentioned cable in the metal member to facilitate the handling of the cable.

[0009] However, when the cable is passed through the above-mentioned closing hole or notch, the cable rubs against the inner wall of the closing hole or notch during use or transportation, so that the insulating coating of the cable is damaged, or the cable is not removed from the notch. There was a problem that it could come off. When the insulating coating of the cable is broken, the conductor of the cable comes into contact with the metal member to cause an electric short circuit, which may cause malfunction or failure of the device. Further, when the cable comes off from the notch, the disconnected cable hinders the driving of the drive unit of the image reading unit and the image printing unit, and there is a possibility that malfunction or failure occurs in the apparatus.

The present invention has been made to solve the above problems, and has as its object to provide a protection device for a metal member that protects a cable and prevents the cable from coming off a notch.

Another object of the present invention is to provide a protection device for a metal member which can be easily mounted on the metal member. Still another object of the present invention is to provide an image processing system for preventing a malfunction or a failure from occurring.
