Description

Description: TECHNICAL FIELD The present invention relates to an image forming sheet storage container used for an image forming apparatus.

[Prior Art] In a conventional image forming apparatus, a photosensitive pressure-sensitive paper constituting an image forming sheet and a color-developed paper as an image-receiving paper for receiving a latent image formed on the photosensitive pressure-sensitive paper are stored in a cartridge or the like. They are housed in a container, and both storage containers are separately mounted at predetermined positions in the apparatus main body.
Further, as the color-developing paper, cut-sheet-shaped paper has generally been used.

[Problems to be Solved by the Invention] However, in this conventional configuration, since the photosensitive pressure-sensitive paper and the color developing paper are stored in separate storage containers, the mounting configuration of the storage container and the paper supply configuration in the image forming apparatus. However, there is a problem that the entire apparatus becomes large, and replenishment of both sheets and conversion of the color-developed paper to different sizes are very troublesome and time-consuming.

In order to solve such a problem, a long photosensitive pressure-sensitive paper and a developing paper are rolled in a state where the photosensitive surface and the developing surface as an image receiving surface are overlapped with each other. It is conceivable that the paper is wound in a single case and housed in one case. However, in such a configuration, as the thickness of the photosensitive pressure-sensitive paper and the color developing paper increases, the difference in the winding diameter between the two rolls in the rolled state is considered. When both sheets are pulled out of the case and become flat, there is a new problem that the length difference between the two sheets causes a wavy pattern. In some cases it was unsuitable.

SUMMARY OF THE INVENTION The present invention has been made in view of the problems existing in the related art, and has as its object to mount a sheet storage container in an image forming apparatus and to supply an image forming sheet. Can be simplified, the entire apparatus can be reduced in size, and the replenishment of the image forming sheet can be performed simultaneously without having to separately perform the operation on the photosensitive thick paper and the image receiving paper. Can be performed easily and in a short time, and even when thick photosensitive paper or image-receiving paper is used, when both papers are pulled out of the case, they should be kept flat without ripples. It is another object of the present invention to provide an image forming sheet storage container that can perform the following.

Means for Solving the Problems In order to achieve the above object, in the image forming sheet storage container of the present invention, a long photosensitive pressure-sensitive paper having a transparent sheet as a base sheet and a transparent or white sheet are used. The long image-receiving paper serving as the base sheet is housed in one case while being wound in a roll shape, and the photosensitive pressure-sensitive paper and the image-receiving paper are joined to each other at the photosensitive agent surface and the image receiving surface. It is configured to be pulled out from the drawer opening of the case in such a state of being overlapped.

[Operation] In the image forming sheet storage container configured as described above, the long photosensitive pressure-sensitive paper as the image forming sheet and the image receiving paper are wound in a roll in a single case. When replenishing the image forming sheet in the image forming apparatus, it is not necessary to separately perform the operation on the photosensitive pressure-sensitive paper and the image receiving paper, and the operation can be performed easily and easily. Can be done in a short time.
In addition, since the mounting portion of the sheet storage container and the supply portion of the image forming sheet can be centrally arranged in the image forming apparatus, their configurations can be simplified and the entire apparatus can be downsized. .

Furthermore, since the photosensitive pressure-sensitive paper and the image receiving paper are each wound in a roll shape, even if thick photosensitive pressure-sensitive paper or image receiving paper is used, there is no possibility that a difference in the winding diameter occurs between the two sheets. Absent. Therefore, even when both sheets are pulled out of the case through the drawer opening and become flat, the sheets are always kept flat without waving. Moreover, since the photosensitive pressure-sensitive paper and the image receiving paper are pulled out from the drawer opening of the case in a state where the photosensitive agent surface and the image receiving surface are overlapped so as to be joined to each other in the case, the photosensitive pressure sensitive paper and the image receiving paper are outside the case. There is no need to provide a structure for superimposing the image receiving paper, and the superimposition accuracy can be improved as compared with the case where both papers are superimposed outside the case.

Hereinafter, an embodiment of an image forming sheet storage container embodying the present invention will be described in detail with reference to FIGS. 1 and 2.

As shown in FIG. 1, the case 1 of the storage container is formed of a light-shielding material so as to prevent light from entering from outside, and is detachably mounted in a main body of an image forming apparatus (not shown). The image forming sheet 2 includes a photosensitive pressure-sensitive paper 3 and a developing paper 4, and the photosensitive pressure-sensitive paper 3 and the developing paper 4 are housed side by side in the case 1 in a state of being wound around spools 5 and 6 in a roll shape, respectively. .

As shown in FIG. 2, the photosensitive pressure-sensitive paper 3 is formed by applying a photosensitive agent 8 on a transparent base sheet 7.
It is wound so that the surface is on the outside. The developing paper 4 is provided on a transparent or white base sheet 9 with a developing agent 10.
Is applied, and the developer is wound so that the surface of the color developer 10 faces inside. The surface of the color developer 10 functions as an image receiving surface for receiving a latent image formed on the photosensitive pressure-sensitive paper.

The drawer opening 11 is formed on one side of the case 1, and a guide roller 12 is provided in the case 1 so as to face the inner end thereof. And the photosensitive pressure-sensitive paper 3
And the developing paper 4 are overlapped on the guide roller 12 such that the photosensitive agent 8 surface and the developing agent 10 surface are joined to each other,
In this state, it is drawn out from the drawer opening 11 to the outside.

The exposure device 13 is provided in the main body of the apparatus, and the image forming sheet 2 pulled out of the drawer opening 11 of the case 1 is provided.
When the light passes through the exposure device 13, a part of the photosensitive pressure-sensitive paper 3 is exposed via the base sheet 7 to form a latent image based on a document or the like. The pressure developing device 14 is provided in the main assembly of the apparatus, and the exposed portion of the photosensitive pressure-sensitive paper 3 and the developing paper 4 are pressed against each other in the pressure developing device 14 so that the latent image on the photosensitive pressure-sensitive paper 3 is developed. Is transferred and developed. The heat fixing device 15 is provided in the apparatus main body, and the image on the developing paper 4 is heated and fixed in the heat fixing device 15.
