Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a copying apparatus having an area designation function for copying only a designated specific area of a document, for example.

[Technical Background of the Invention and Problems Therewith] In recent years, copying devices are required to have image editing functions such as image reduction/enlargement, shift, area designation, and insertion. In response to these demands, digital copying apparatuses are attracting much attention because they can easily perform the above-mentioned image editing function.

For example, a digital copying device like this has a carriage that moves while shining light onto the original, an optical system that focuses reflected light from the original onto a predetermined position, and a position where this light is focused. a line sensor that converts an optical signal into an electrical signal; an A/D converter that converts the electrical signal from the line sensor into a binary signal; and a binary signal from the A/D converter. The main parts thereof include a memory that stores the information, and a printer that forms a copy image based on the binary signal stored in this memory.

Then, the light emitted from the carriage is irradiated onto the document, and the reflected light is focused on the line sensor via the optical system, thereby converting the optical signal into an electrical signal, and roughly converting this electrical signal into an A/D This is done by converting the data into binary data using a converter, storing it in memory, and copying it onto a recording material using a printer.

By the way, the area specification function in the image editing function mentioned above is a function that copies only a specified specific area of a document, and the conventional method of specifying a specific area of this document is to specify an address using a keyboard. There is a method of specifying an address by using a touch panel to specify the method and number of copies.

However, in all of the above-mentioned methods, the operation is extremely troublesome, and there is a problem in that only areas with simple shapes, such as rectangular shapes, can be specified.

[Object of the Invention] The present invention was made in response to the above-mentioned circumstances, and it is an object of the present invention to provide a copying device that can make the copying area of a document into an arbitrary shape and that can be easily operated. .

[Summary of the Invention] That is, the copying apparatus of the present invention includes: a record reading means for reading recorded information on a document; a copying means for copying recorded information read by the record reading means onto a recording member; area reading means for reading a copy area displaying a specific area; area storage means for storing the area read by the area reading means; and area storage means for storing the area read by the area reading means; By providing a copying area control means for copying only the copying area, the copying area of the document can be made into any shape and the operation thereof can be easily performed.

[Embodiments of the Invention] Hereinafter, details of embodiments of the present invention will be described based on the drawings.

FIG. 1 is a diagram for explaining the copying apparatus of this embodiment.

This copying device is a digital type copying device, and as shown in the figure, it has a reading section A, a signal processing section B, and a copying section C.
The main part is composed of.

The reading section A includes a document table (not shown) on which the document 1 is placed;
A moving device (not shown) that moves the document table, a light source 2 that emits ultraviolet rays, a light source 3 that emits visible light, and a light source 2.3 that emits visible light that reflects the reflected light from the document 1. an optical system 4 that focuses light on a predetermined position;
The light source 2.3, the optical system 4 and the line sensor 5 are arranged in a device consisting of
are arranged in a direction perpendicular to the moving direction of the document 1, respectively.

The signal processing section B also includes an A/D converter 6 that converts the electrical signal output from the line sensor 5 into a binary signal of a predetermined level depending on the strength of the signal, and an A/D converter 6 that converts the electrical signal output from the line sensor 5 into a binary signal of a predetermined level. A memory 7 stores only the binary signal as a copying range designation signal, and a binary signal of the reflected light from the light source 3 is stored as a signal within a designated range based on the copying range designation signal stored in the memory 7. A gate 8 for extraction, a memory 9 for storing the signal extracted by the gate 8, a reading section A,
CPU1 that controls the operation of signal processing section B and copying section C
0.

The copy section C is controlled by the CPU 10 and has a memory 9.
The printer 11 forms a copy image on a recording member based on signals stored in the printer 11.

The thus configured copying apparatus operates as follows.

As shown in FIG. 2, first, the area 12 to be copied on the original
With a special ink pen that emits visible light when excited with ultraviolet light, write and surround it as shown in Figure 13. Then, the original 1 is placed on the original table and the copying operation is started.

At this time, first, the light source 2 is turned on and emits ultraviolet light, and the original 1 together with the original table starts moving in the direction of the arrow 14 in FIG. 1. Then, the original 1 is irradiated with ultraviolet rays, and the line 13 drawn with the special ink pen on the original 1 emits visible light. The emitted visible light is then focused on the line sensor 5 via the optical system 4, and is input to the signal processing section B as an electrical signal.

The electrical signal from the line sensor 5 is then processed by the signal processing section B.
This electrical signal is converted into a binary electrical signal by the A/D converter 6, roughly written with the special ink pen, and the enclosed inner part is stored in the memory 7 as a copy range designation signal.
is memorized.

When the entire surface of the original 1 is scanned by the light source 2, the light source 3 is turned on, and while visible light is irradiated onto the original 1, the original 1 moves together with the original table in the direction opposite to the arrow 14 in the figure.

At this time, reflected light, which is information read from the surface of the original 1, is focused on the line sensor 5 via the optical system 4, and converted into a binary signal by the A/D converter 6.

Further, from this binary signal, a gate 8 extracts a binary signal from the document surface of the document 1 within the designated range based on the copy range designation signal stored in the memory 7, and then this extracted signal is extracted. Only the detected signals are stored in the memory 9.

Thereafter, a copy image is formed on the recording member by the printer 11 based on the signals stored in the memory 9.

In this way, the area to be copied on the original 1 can be specified by writing on the original 1 with a special ink pen that emits ultraviolet light and enclosing it, so the operation is very simple. An area can be specified in any shape such as a circle, triangle, special shape, etc.

Furthermore, by irradiating the original 1 with the light source 2 and the light source 3 on the forward and return journeys of the original 1, the irradiation of the original 1 with the light source 3 can be regenerated from the original irradiation of the original 1 with the light source 2. There is no need to return to the original position and copying time can be shortened.

The color of the special ink pen in the above-described embodiment may be any color, but by making this color transparent, the original 1 can be used again as the original after copying the original.

[Effects of the Invention] As explained above, according to the copying apparatus of the present invention, the area reading means reads a copying area displaying a specific area written on a document, and the copying means makes copies based on this copying area. Since only the area can be copied, the copy area of the original can be made into any shape, and its operation is easy. −
