Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital copying machine which can easily perform partial image processing on a document.

[0002]

2. Description of the Related Art In a conventional digital copying machine, when performing partial image processing (partial copying, partial blanking, etc.),
It is common to use a document that has been marked in advance with a marking pen or the like. The marked original was placed on the copying machine and the coordinate points were transmitted to the image processor by appropriate means.

FIG. 3 is a sectional view showing the structure of a conventional digital copying machine.

In FIG. 1, the document is scan-exposed by the scanning light source 1 arranged below the document 15, and the reflected light is photoelectrically converted by the CCD 2 to be converted into an electric signal. The electric signal is image-processed by the image processor 3,
It is output as image processing data. The image processing data is sent to the laser diode (LD) 4, and the LD 4 is turned on and off according to the image processing data.

The laser light from the LD 4 passes through the polygon mirror 5 and exposes the photosensitive drum 6 to form an electrostatic latent image on the photosensitive drum 6. The photosensitive drum 6 rotates clockwise, and the electrostatic latent image is visualized by the toner as it passes through the developing unit 8. The visible image is conveyed to the photosensitive drum 6 along the arrow A. It is transferred to the recording paper by the transfer charger 9a, and the recording paper is separated from the photosensitive drum 6 by the separation charger 9b. The transferred visible image on the recording paper is fixed by the fixing unit 10. The recording paper exiting the fixing unit 10 is ejected as a copy of the original along the direction of arrow A.

On the other hand, the photosensitive drum 6 after transfer is cleaned by a cleaning unit 11 to remove residual toner on the surface.

[0007]

In the digital copying machine having the above-mentioned structure, in order to specify the range of partial image processing,
The manuscript had to be subjected to processing such as writing the manuscript to specify the range area, and when the manuscript was to be stored as it was, another copy had to be made and one of them had to be preserved. Further, when an erasable marking pen is used, complicated work such as erasing the marking is required.

An object of the present invention is to provide a digital copying machine which can easily specify the range of a partial image processing area in a copying operation involving partial image processing.

[0009]

In order to achieve the above object, the present invention installs a contact glass also serving as a touch panel above the original installation surface of a copying machine, and further above the contact glass. The main feature is to install a scanner unit that scans, and when the user touches the contact glass with a finger or the like, the image processor that conveys the information of the specified area and the document processing information are combined. Based on the information
A digital copying machine, comprising a laser diode whose lighting and extinguishing are controlled.

[0010]

According to the above-mentioned means, above the document placement surface,
By installing a contact glass that doubles as a touch panel, and by installing the scanner section above the contact glass, the user can see the original through the contact glass and also use the contact that doubles as the touch panel for the area where you want to perform partial image processing of the original. It is possible to specify easily by touching the glass with a finger or the like.

Further, when the original is scanned and exposed, the information of the designated area on the contact glass also serving as the touch panel is transmitted to the image processor and becomes the information combined with the image processing information instructed by the user. Based on, the turning on and off of the laser diode is controlled.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view showing the structure of an embodiment of the present invention. Also in this figure, since the basic structure of the copying process is the same as that in FIG. 3, the members corresponding to the members described with reference to FIG. 3 are designated by the same reference numerals, and the description thereof will be omitted.

To explain the difference between FIG. 1 and FIG. 3, a touch panel / contact glass 12 for opening and closing in the direction of arrow B is provided above the installation surface of the original 15, and the contact glass is provided above the contact glass. That is, the scanner unit 13 that performs the same operation as is provided. The scanner unit 13 is a scanning light source 1 for scanning a document.
And a CCD 2 for photoelectrically converting light reflected from the original.

In FIG. 1, a touch panel / contact glass 12 is placed on a document 15 placed at a predetermined position of a copying machine body 14.
Close. At this time, when the user wants to take a copy of the original 15 by partially performing image processing (partial copying, partial whitening, etc.), the user needs to touch the touch panel and contact glass as shown in FIG.
While observing the original 15 through the document 12, a region (shown by a broken line in FIG. 2) to be partially image-processed is designated by touching it with a finger or the like to close the scanner unit 13. At this time, there are various methods of specifying the area using the touch panel,
A generally known one is used. For example, a method of enclosing the area with a line drawn by detecting the touch of a finger,
A method of setting an area at a coordinate point determined by detecting contact with a finger or the like can be considered. In this embodiment, a method of setting coordinate points with a finger is used.

The scanner unit 13 arranged above the document 15
The original is scan-exposed by the internal scanning light source 1. At that time, the information of the area designated on the touch panel / contact glass 12 and the image processing information instructed by the user are combined in the image processor 3, and the turning on / off of the LD 4 is controlled based on this information. Then, an electrostatic latent image is formed on the photosensitive drum 6.

Thereafter, development, transfer and fixing are performed in the embodiment of the present invention along with a copying process similar to that of the conventional example, and the partially image-processed copy is discharged.

[0018]

As described above, according to the present invention, when a touch panel / contact glass on an original is brought into contact with a finger or the like, when the original is copied with partial image processing, the original is copied. It is not necessary to perform marking in advance, and it is possible to easily specify a region in which partial image processing is performed.
