It is needless to say that the storage form may be changed as necessary, such as when the storage medium is composed of a plurality of media, such as distributed arrangement.

Here, the document description information storage area 11a is
This is an area for storing the document description information described in the document before cutting. The document description information is not limited to the information acquired by the document description information acquisition unit 14 of the shredder 10 as it is, and may be regenerated / processed based on the acquired information. Specifically, it is not limited to the image information format (image format), and may be stored in the document information format (browsing format).

The status classification database 11b is a database that defines status classifications according to the printing status of the cut document. The state classification may be based on at least one of black-and-white printing and color printing, or the area ratio of the print area of the document. FIG. 2 shows an example of a data structure diagram of the state classification database 11b according to this embodiment.

As shown in FIG. 2, the status division database 11b stores the divisions C1, C2, C3, C4 and BW.
It specifies the types of documents corresponding to 1, BW2, BW3, and BW4. Here, the classification code is a symbol that represents a classification according to the printing state of the document, and the printing type depends on the type or combination of ink or toner used for printing, such as color printing or monochrome printing. The area ratio means a ratio calculated by using the total area of the printed surface of the document as the denominator and the area of the actually printed area as the numerator.

Specifically, in this embodiment, the printing is divided into black-and-white printing and color printing, and further subdivided by the area ratio of the print area of the document.

This division takes into consideration the labor of recycling treatment such as decoloring and bleaching of ink and toner.By subdividing this division, it is possible to sort and store according to the amount of labor for processing shredder dust. .

The number of state categories and the criteria for setting the boundaries thereof are not limited to the above eight patterns, and the state categories may be at least black and white printing or color printing.
Alternatively, it may be based on one of the area ratios of the print area of the document. For example, if it corresponds to the shredder dust recycling process, it is classified into color printing (5 types of ink or toner), mono-color printing (2 types of ink or toner), and monochrome printing (1 type of ink or toner). May be. Further, the printing area ratio may be finely divided in 10% increments.

However, the area ratio is a standard and is a standard as a standard for roughly obtaining the amount of ink or toner used on the paper in a standard paper unit. Therefore, in a special printing form such as double-sided printing, the amount of ink or toner used per unit paper is calculated based on the area ratio. Specifically, the surface is 25
% And the back surface is 50%, the area ratio is treated as 75%.

Subsequently, the classification corresponding amount storage area 11c is a storage area for storing the classification corresponding amount of the document corresponding to the status classification set in the status classification database 11b described above. Here, the category corresponding amount refers to the amount of documents corresponding to each state category, and has the paper size and the number as parameters. Therefore, if a predetermined standard paper size is set and the paper size of the document to be cut is converted to that standard paper size, the amount may be the category applicable amount, or the paper size and the quantity may be directly associated without conversion. It may be a quantitative parameter. As an example when not converting,
One way to count is one A3 size and one B4 size.

In the present embodiment, the classification applicable amount is a numerical value (converted quantity) converted into a quantity corresponding to a predetermined reference paper size. Specifically, the standard paper size is A4,
If the shredding paper is A4 size, the quantity is 1, A
For 3 size, the quantity is 2, and for B4 size, the quantity is 1.5. However, even in the case of A4 double-sided printing or the like, since there is only one sheet, the classification applicable amount is 1. The standard paper size is not limited to A4, and may be set according to the charging system for shredder use. For example, the B5 size may be used as a reference.
