DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing apparatus such as a facsimile machine, a scanner, or a printer.

[0002]

2. Description of the Related Art As is well known, for example, in a facsimile apparatus, in order to constitute an image reading processing section for reading an original image and then processing the data, an image reading sensor and a control circuit for processing an image signal are appropriately provided. It is necessary to connect wiring using a harness. Also, the document feed motor for transferring the document in the sub-scanning direction needs to be connected to the control circuit by using an appropriate harness.

In the case where such a wiring is provided in a housing of a facsimile apparatus, a first harness for connecting an image reading sensor and a control circuit and a second harness for connecting a document feed motor and a control circuit are provided. It is not preferable that the wiring is performed in completely different paths, because the wiring space efficiency in the housing is deteriorated. Therefore, in order to solve such a problem, it is desired that the first harness and the second harness be integrated into one wiring path as much as possible.

[0004]

However, conventionally, when the two harnesses are combined into one wiring path, the following problems occur.

That is, the second harness supplies, for example, a 24 V pulse driving power to the document feed motor, and has a voltage higher than a voltage (for example, 5 V) supplied to a general electronic circuit. Is generally set to. Further, the document feed motor connected to the second harness easily generates electromagnetic noise. Therefore, if the second harness and the first harness are brought close to each other in an attempt to combine them in the same wiring path, noise is mixed in the image signal transmitted to the control circuit by the first harness. The likelihood was high. Such mixing of noise causes the noise portion to appear improperly as a black pixel or a white pixel when an image signal is subjected to, for example, black and white binarization processing in the control circuit. As a result, conventionally, there has been a problem that the quality of the reproduced image of the original image read by the image reading sensor is reduced due to the influence of the noise. As described above, in the related art, in order to improve the wiring space efficiency of the first harness and the second harness, they may be brought close to each other.
There has been a problem that the image quality is reduced.

[0006] The above-mentioned problem occurs not only in a facsimile apparatus but also in other image processing apparatuses such as a scanner apparatus. Also, the phenomenon that noise is mixed in the image signal occurs not only when the image signal is transmitted from the image reading sensor to the control circuit,
For example, this also occurs when an image signal is transmitted from a control circuit to a printer head.

The present invention has been devised in view of such circumstances, and a harness for transmitting an image signal and a harness for supplying driving power to a predetermined driving device in an image processing apparatus are provided. It is an object of the present invention to improve the wiring space efficiency of these wirings and to appropriately eliminate the improper noise from being mixed into the image signal transmitted by the one harness by simple means.

The harness 25 for connecting the motor is conveniently prevented from approaching a certain distance or more by the other harnesses 22 to 24 arranged between them.

In the facsimile apparatus F having the above configuration, since each of the plurality of harnesses 21 to 25 is arranged in a single groove 30,
Space efficiency for wiring the plurality of harnesses 21 to 25 in the housing 3 is improved. Further, when performing the wiring work of the plurality of harnesses 21 to 25, a part of each of the harnesses 21 to 25 may be sequentially accommodated in the groove portion 30, so that the work is also easily performed.
