Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus such as an electronic copying machine for making a large size recording paper as shown in a drawing and the like, and to a post-processing apparatus arranged at a recording paper discharge portion thereof. , In particular, a mechanism for winding a long recording paper into a cylindrical shape by a paper winding device, applying an adhesive tape for sealing, discharging the recording paper formed as a wrapping paper, and sealing with a commercially available labeler Regarding the device.

[0002]

2. Description of the Related Art In an image forming apparatus such as an electronic copying machine or a laser printer which produces a recording sheet by using an electrophotographic method, a sheet cut into a standard size such as A3 or B4 size is used. Use, according to the size of the original,
Means for selecting a suitable size of paper and creating a recording paper are used. In the electronic copying machine, a plurality of paper feed trays, paper feed cassettes, and the like are housed in a paper feed unit, and paper is selected based on information such as the size of a document and a reduction ratio.
It constitutes a means for feeding paper toward the image forming unit. Then, the recording paper created in the image forming apparatus is passed through a fixing device to be fixed, and then discharged toward a discharge tray or the like.

Further, in addition to the electronic copying machine using the small size paper as described above, in an electrophotographic copying machine used for creating a drawing or an image forming apparatus such as a plotter, A0 size or A1 size is used. A recording paper is created using a large size paper such as a size. An electronic copying machine will be described as an example of the image forming apparatus for the drawings. For example, as shown in Japanese Patent Application Laid-Open No. 1-187133, a wide roll paper is attached to a paper feeding unit,
An apparatus configured to cut a sheet fed from a roll sheet in accordance with the size of a document to create a large-sized recording sheet is used.

[0004]

However, the recording paper created by the large-sized electronic copying machine can be discharged as an arbitrary length, but in the conventional electronic copying machine, a long recording paper is used as it is. It is discharged in a continuous state and is deposited as it is on a receiving member such as a large box. Then, for the long recording paper as described above, it is necessary for the operator to stand by at the recording paper discharge section and perform work such as winding the long recording paper. Therefore, in the conventional electronic copying machine, particularly when a long recording paper is created, the recording paper is prevented from being scattered at the discharge port of the apparatus.
It is necessary to organize the recording paper.

Using a large-sized original document as described above,
In addition to the case of creating recording paper, in recent large-sized electronic copying machines, an image information output device such as a computer is used.
There is a case in which a mechanism for continuously ejecting a large-sized recording paper is configured according to the image information output from the output device in combination with the electronic copying machine. In an apparatus that connects an output device such as a computer to an electronic copying machine to create a large-sized recording sheet, a plurality of output devices may be connected to one electronic copying machine. Therefore, in response to a recording paper creation command from any output device,
When making recording paper, unless the operator is always standing by the electronic copying machine, the recording paper cannot be sorted and large-sized recording paper is scattered around the electronic copying machine. Occurs.

Therefore, in order to solve the above-mentioned problems, a device for folding a large size recording paper into a standard size is also used. As the sheet folding device, for example, a device configured as shown in JP-A-63-196462 can be used. However, generally, a drawing created using a plotter or the like has originality and is often used for confirmation of a concept check on a recording paper. Therefore, it is not preferable to use the folding device as shown in the above-mentioned conventional example, and there is a problem in post-processing when a large size recording paper is prepared.

Therefore, instead of using the folding device as described above, for example, the actual flat plate 1-149363.
As disclosed in Japanese Unexamined Patent Application Publication No. 2003-242242, it has been proposed to arrange a paper winding mechanism with respect to a discharge tray for discharging recording paper so that the work of checking the recording paper can be performed easily. In the recording paper processing device shown in the conventional example,
By arranging a mechanism for winding the paper at the end of the output tray and holding the long recording paper in a cylindrical shape, it is not necessary for the operator to wind the recording paper during the copying operation. The processing work can be simplified. However, as described above, even when the mechanism for automatically winding a long recording paper is arranged, the recording paper is taken out from the discharge tray every time one recording paper is discharged.
It is required to move to another containment device. Further, the roll-shaped recording paper may easily spread to its original state in a state where it is not sealed, and there is a problem that the subsequent storage becomes troublesome. Furthermore, when continuously producing large-sized recording paper, the operator is required to process a long original and a cylindrical paper each time one recording paper is prepared, which is relatively troublesome. It is necessary to successively perform such operations.

Further, as described above, when the mechanism for sealing the wrapping paper is provided, for example, even when the means for sealing using the adhesive tape is provided, the mechanism for supplying the adhesive tape is simple. Although it is required to have a structure, in the conventional device for sealing a wrapping paper, only a device for winding the entire circumference is used. However, when such a long adhesive tape is used, there is a problem that the processing of the recording paper is troublesome when opening the wrapping paper later.
Furthermore, when a long tape is used, the cost of the tape becomes relatively high, and in addition, the work time becomes long.
