Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus in consideration of recycling of transfer paper used in a copying machine or the like.

[0002]

2. Description of the Related Art Conventionally, in an image forming apparatus, particularly an electronic copying machine, it has been general to form only an image of an original on a transfer paper. However, in recent years, due to improvements in technology such as laser printers, an image is read by an image pickup device (CCD) and a digital copying machine that writes image information on a photoconductor by a laser or the like, or a conventional analog copying machine by a laser or other means. Hybrid copiers, which can print by adding information other than the information on the manuscript, have appeared on the market.

Information other than the information on the manuscript includes, for example, the date and time when a copy is made at the corner of the transfer paper, the character "hidden", etc. By attaching this information to the transfer paper,
Make it easy to recognize the date and time when the copy was made, and call attention to the handling of the photo transfer. By adding such new functions, we have realized a copying machine with higher added value.

On the other hand, in recent years, a recycle movement of transfer paper has been actively carried out to protect forest resources, and a system for collecting used paper after copying is gradually permeating society. However, transfer paper in general companies often contains internal information of the company, and in order to prevent the information from leaking to the outside, the paper is often cut into small pieces with a shredder.

By the way, when reusing used copy paper, it is desirable that the fibers of the paper of the copy paper are in a state before cutting as much as possible. Is almost impossible to use.

[0006] To erase the information on the transfer paper without damaging the fiber of the paper, for example, the used copy paper is strictly stored so as not to be taken out to another place, and a recovery contractor who concludes a secret contract. However, it is natural that some companies think that confidentiality is more important to companies than the need for recycled paper at present. However, it is difficult to collect used paper while maintaining confidentiality for recycled paper even by a laborious work. As described above, reproduction of copy paper has conflicting conditions such as confidentiality, and it is difficult to easily reproduce the copy paper.

Further, turning to the structure of the paper, the paper is sold by a large number of manufacturers, but if it is limited to a specific size of a specific manufacturer, the lengthwise direction (or the lateral direction) of the paper will be considered. In many cases, the grain direction of the paper (hereinafter referred to as the fiber direction) is constant, and this is because it is determined by the conditions in the manufacturing process of the paper.
In this way, if the fiber direction of the paper is constant, if the paper is cut only in that direction, the degree of damaging the fiber of the paper is minimized, and it is possible to obtain a raw material that can produce recycled paper of relatively good quality. You can.

There are two types of shredders, one for cutting the paper into squares of 2 to 5 mm, and the other for cutting the paper into long and slender pieces in parallel only to the direction of paper entry. If you insert the paper into the shredder in the same direction as the fiber direction, considering the direction, the fibers of the elongated paper after being shredded are parallel to the cutting direction, so it is suitable as a raw material for recycled paper. become.

[0009]

However, even if the above is known, it is impossible for a general user to judge the fiber direction of the paper at a glance, and the paper can be torn by hand. Even if you can check the fiber direction of the paper,
Finding the fiber direction of various sizes of paper is a very tedious task, and it is very difficult to recognize the fiber direction of the used transfer paper and make the transfer paper shredded so that it can be regenerated. there were.

The present invention is intended to solve the above problems. That is, it is an object of the present invention to provide an image forming apparatus capable of transferring information indicating the fiber direction to a required portion of a transfer paper.

In order to achieve this object, a conventional digital copying machine which is one of the image forming apparatuses suitable for applying the present invention will be described with reference to FIG. In FIG. 5, a document placed on the document table glass 7 is irradiated with light by a lamp (not shown), and reflected light from the document is incident on the lens 9 via mirrors 8a, 7b and 8c.
The mirror group scans all information such as characters printed on the document, and therefore moves in the direction of arrow A. The light that has scanned the original and passed through the lens 9 is digitally converted into an image signal by an image pickup device (CCD) and an A / D converter (see FIG. 4), and this signal is subjected to color separation and shading correction in an image processing unit. Required processing such as equal processing is performed and converted into a video signal. Based on this signal, the laser emitting device emits a laser to the polygon mirror 10, and this light is emitted from the mirror 1.
It is irradiated to the drum 12 via 1. The transfer paper 13 is stacked in a cassette 14, one of the uppermost papers is fed by a paper feed roller 15, and reaches a register roller 18 via rollers 16 and 17. A latent image is formed on the drum 12 by the laser, and the latent image is developed by the developing device 19 to form a toner image on the drum 12. With respect to this image, the register roller 18 rotates at a timing, and the paper is conveyed to the drum 12.

The toner image on the drum 12 is transferred to the transfer charger 2.
The paper on which the toner image has been transferred by the 0 is transferred to the fixing device 22 by the carrying portion 21, and the fixing device 22 fixes the paper. Thereafter, the transfer paper passes through the paper discharge roller 23 and is stacked on the paper discharge tray 24. This device has a CC between the lens 9 and the polygon mirror 10.
Since there is a D, AD converter, image processing unit, etc., it is possible to easily form an image by adding information such as characters stored in the machine in advance in addition to the information on the document.

The present invention is intended to solve the above problems, and particularly to facilitate the solution in the above copying machine. That is, an object of the present invention is to provide an image forming apparatus capable of transferring the information indicating the fiber direction to a required portion of the transfer paper at the same time as the information on the document.

[0014]

In order to achieve the above object, an image forming apparatus of the present invention is an image forming apparatus capable of simultaneously transferring original document information and information other than the original document information on the same transfer paper. In the apparatus, a unit for storing information on the fiber direction of the transfer paper corresponding to the size of the transfer paper, an input unit for the size of the transfer paper, and a digital device based on the input of the size of the transfer paper and based on the information on the fiber direction. It has a means for generating a signal and an image processing means for adding the digital signal to the digital signal based on the document publication information.

[0015]

According to the present invention, the means for storing the information on the fiber direction of the transfer paper corresponding to the size of the transfer paper, the input means for the size of the transfer paper, and the fiber for receiving the input of the size of the transfer paper. Since it has means for generating a digital signal based on the direction information and image processing means for adding the digital signal to the digital signal based on the document publication information, the information posted on the document and the fiber direction information of the transfer paper And can be simultaneously transferred to a required portion of the transfer paper.

[0016]

Embodiments of the image forming apparatus of the present invention will be described with reference to FIGS.

In FIG. 4, reference numeral 9 is a lens, and 10 is a polygon mirror, which is the same as the conventional one shown in FIG.
The light passing through is converted into a digital signal through the image sensor CCD and the AD converter. Reference numeral 31 is an image processing unit, 32 is a CPU, and 33 is a storage unit. The storage unit 33 stores the conventional information such as the control program of the CPU and the data regarding the "secret" character attached to the corner of the transfer sheet. In addition to these pieces of information, in the present invention, the storage unit 33 stores information indicating the fiber direction according to the type of paper and the size of the transfer paper, for example,
It stores a symbol such as an arrow indicating the fiber direction, a figure, a sentence such as "Please insert from here when putting on a shredder", and information about the size of the letter.

The information indicating the fiber direction corresponding to the type and size of the transfer paper is preferably stored in the ROM, but may be input from the input means 34. Further, the storage unit 33 receives the information on the transfer location of the information indicating the fiber direction, the size and type of the transfer paper from the input unit 34, and temporarily stores the information.

Next, the procedure of the operator's preparation work for handling the present invention will be described with reference to FIG. This work is performed by the input means 34 provided in the operation unit. Since the fiber direction of the transfer paper may differ depending on the type of paper,
Before operating the image forming apparatus, it is necessary to register the fiber direction of the paper corresponding to the paper type, the paper size, and the size. However, in one image forming apparatus, the type of paper can be limited to several types except when the paper is manually inserted, and once the fiber direction is registered, it is not necessary to change it frequently. Further, it is considered that the fact that the fiber directions are different in the same type of paper is hardly due to the convenience of the paper production. Also, in FIG. 1, A4R, B5R, etc. are automatically determined, but this is the same as the conventional one and is not a requirement of the present invention. Next, the information indicating the fiber direction, for example, the position where the arrow is printed is designated by the input unit 34. The information indicating the fiber direction is transferred to a position where the characters such as characters are very unlikely to exist in the document such as a document at the most end side of the transfer paper, and is positioned as far as possible without hindering the transfer of the information on the document. Further, in recent years, many image forming apparatuses are also equipped with an automatic double-sided copying machine,
It is also possible to consider that the information indicating the fiber direction is transferred to the back surface of the transfer paper and no extra information other than the information on the document is added to the front surface of the transfer paper.

In the apparatus of the present invention in which the above preparatory work has been completed, when the user starts copying, the light that manipulates the information on the document is converted into a digital signal through the lens 9, CCD, and AD converter. , To the image processing unit 31.
On the other hand, the CPU 32 retrieves the information indicating the fiber direction such as the symbol indicating the fiber direction stored in the storage unit 33, and sends the information to the image processing unit 31 as a digital signal via the AD converter. The image processing unit 31 adds this digital signal to the digital signal of the information on the document and sends it to the laser transmission device 35, and the laser modulation device 35 emits a laser beam corresponding to the both digital signals. The laser beam charges the photosensitive drum via the polygon mirror 10 to form a latent image, but the following image formation is the same as the conventional one.

As described above, as shown in FIG. 2, finally, the information 1 on the document and the information 2 on the fiber direction are copied on the transfer paper 13.

In the above embodiment, the fiber direction input means has been described as a manual operation means on the operation portion. However, in another embodiment of the present invention, as shown in FIG. It can be done by similar means. For example, five grooves 5 are provided at the rear end of the cassette 4 on which transfer sheets are stacked, and pieces 6 are appropriately inserted in the grooves. These pieces 6 are microswitches connected to the storage unit 33. Face 3

As shown in the figure, every other frame 6 is sequentially mounted from the right groove 5, and when the cassette 4 is inserted into the main body of the image forming apparatus in the direction of arrow B, the micro that is pushed by the frame and turned on. When the signal of switch 3 is 1, the signal is 1.
It becomes 0101. In this case, the paper size is identified by the 4-digit signal from the beginning, and the last 1 digit is used to identify the fiber direction of the transfer paper. If the paper transport direction and the fiber direction are parallel, 1 (frame mounting), parallel If not, 0 (without frame)
When the cassette 4 is inserted, the information on the fiber direction of the transfer paper can be automatically stored in the storage unit by designating the above or vice versa.

[0024]

As described above, according to the present invention,
In an image forming apparatus capable of simultaneously transferring the manuscript information and the information other than the manuscript information on the same transfer paper, the information on the fiber direction of the transfer paper is stored in association with the size of the transfer paper, and the information of the transfer paper is stored. In response to the size input, a digital signal is generated based on the fiber direction information, and the digital signal is added to the digital signal based on the document publication information. Can be simultaneously transferred, and as a result, the used transfer paper is shredded according to the fiber direction information, so that the fibers of the transfer paper are not cut.
