Abstract

PURPOSE:To adequately set the set conditions of a copying machine on transfer paper even if the arbitrary transfer paper is used by stating the information on the properties of the transfer paper on the transfer paper. CONSTITUTION:The transfer paper is packaged in a bundle and is attached with data paper indicated with bar codes as the information on the properties of the transfer paper in the uppermost part or the lower part or both thereof. The information on the properties of the transfer paper disposed in the upper part of a paper feed section is read by a reading means, such as bar code reader, and the respective set values of the copying machine are most adequately set by the read information when the data paper is put into the copying machine. The same bar codes are displayed at four points in the same positions with respect to the sides of the data paper and are readable even if the transfer paper is set in any directions. Further, the flanks of the transfer paper bundle may be displayed by the bar codes as well and in such a case, the similar effect by the similar sequence if a bar code reading means, etc., are provided on the flanks of the paper feed section of the copying machine.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to the thickness of transfer paper, electric resistance, electric conductivity, surface roughness, coefficient of friction, water content, amount of paper powder,
The present invention relates to a transfer paper for a copying machine, in which various physical properties such as rigidity and talc amount that affect setting conditions of the copying machine are described in advance.

[0002]

2. Description of the Related Art Conventionally, transfer sheets used in copying machines have been limited to those which meet various setting conditions of the copying machine.

[0003]

In the above-mentioned conventional example, the process setting condition of the copying machine is not set to the optimum value for the transfer paper used in the copying machine. Therefore, the transfer charger of the copying machine is used. It was easy for transfer defects to occur due to wire contamination, changes in environment such as humidity and temperature, and mechanical conditions. or,
When using paper with a large amount of paper dust, the cleaning blade clogged up quickly and cleaning failure occurred before regular service. Further, in the case of thick paper, fixing failure occurred.
Therefore, the object of the present invention is to solve the above-mentioned drawbacks of the prior art, and even if an arbitrary transfer paper is used, the setting conditions of the copying machine are optimally set to the transfer paper to be used, that is, the copying machine and the transfer paper. It is an object of the present invention to provide a technique capable of always providing a good quality copy regardless of an arbitrary combination with paper.

[0004]

The above object can be achieved by the present invention described below. That is, the present invention is a transfer paper for a copying machine, in which the physical property information is described.

[0005]

The physical properties of an arbitrary transfer paper are recorded in advance, and this information is read by the copying machine so that the setting conditions of the copying machine are optimally set to the transfer paper. Even if it is used in any copying machine, good quality copying is always possible.

1 is a schematic illustration of a stack of transfer paper for a copier according to the present invention. Transfer paper is usually 500 to 1,0
Every 00 sheets are packed in a bundle, and data sheets with physical property information of the transfer paper and a bar code or the like are attached to the uppermost part, the lowermost part, or both. This data paper,
When placed in a copying machine as shown in FIG. 5, the reading means such as a bar code reader reads the physical property information of the transfer paper placed on the upper portion of the paper feeding section, and the read information allows various kinds of copying machines. Is set to the optimum value for the transfer paper.

FIG. 5 is a sectional view of a copying machine using the transfer sheet bundle of the present invention. Since this is a copying machine using an ordinary electrophotographic process, its general details are omitted. Regarding the point related to the present invention, 1 is a cassette for storing paper, 2 is a feeding roller, 3 and 4 are retard roller units for preventing double feeding of paper, and 5 and 6 are registration rollers. 7 is a transfer sheet bundle of the present invention, 8 is a lamp, 9 is a reading lens, 1
Reference numeral 0 is a CCD array, which is used to read the information on the data paper on the uppermost layer of the transfer paper by 8, 9, and 10.
The data sheet is not copied but is discharged from the normal discharge section through the transport path. For example, the transfer current value is set to the optimum condition by the electric conductivity or the electric resistance value of the paper, and the temperature of the fixing roller is set to the optimum condition by the paper thickness value. Further, since the water content of paper affects the curl amount after fixing, the loading amount of the sorter or tray is set by the water content. Further, the torque limit value of the retard roller of the paper feeding system is set by the friction coefficient between the paper sheets.

In addition, the life of the paper feed roller is displayed according to the surface roughness of the transfer paper, and the optimum information regarding the service such as the cleaning interval of the cleaning blade is displayed according to the amount of paper powder of the transfer paper and the added substance. You can do it. The same bar code is displayed at four positions at the same position with respect to the side of the data sheet, and the bar code can be read even if the transfer sheet is set in any direction. In FIG. 2, a bar code is displayed on the side surface of the transfer sheet bundle. Although not shown, a bar code reading means or the like is provided on the side surface of the sheet feeding portion of the copying machine, and the same as in the embodiment shown in FIG. The same effect can be obtained by the sequence. FIG. 3 shows the physical property information of the transfer paper on the wrapping paper. In this case, it is necessary for the operator to have the barcode reader read the barcode. In FIG. 4, various physical properties of the transfer paper are directly displayed on the ends of the transfer paper by bar codes. This is displayed in the margin of the tip. In addition, even if a card in which physical property information is described is included in the package of the transfer paper bundle, the same effect as the above can be obtained.

[0009]

According to the present invention as described above, the following operational effects are exhibited. (1) Since the transfer paper is always copied under optimum setting conditions for the transfer paper, a good quality copy can be obtained. (2) Service maintenance suitable for the transfer paper becomes possible. (3) A copying machine is provided which can use various kinds of transfer papers suitable for the intended use.
