[Example] Hereinafter, in order to explain the present invention more specifically, an example will be given and explained.

FIG. 2 is a schematic sectional view of a photosensitive and pressure sensitive copying machine that is capable of full color copying. Incidentally, a photosensitive paper (consisting of microcapsule paper and color developer paper) that enables such copying has been proposed in Japanese Patent Application Laid-Open No. 58-88739, etc., and will not be described in detail here.

As shown in the figure, in the photosensitive and pressure sensitive copying machine 40, a desired document is placed and moved face down between a document table glass 2 and a document table cover 1, the top plate of which is movable in the horizontal direction. At the same time, the norogen lamp 3 extending in the direction perpendicular to the direction of movement of the document platen glass 2 is turned on, and the light is irradiated onto the document surface on the document platen glass 2 in a line shape through the reflecting mirrors 4 and 5.

The reflected light from the original passes through the filter 8 and is irradiated via the lens 9 and the reflection mirror 11 onto the surface of the microcapsule paper 37 that is transferred in a fixed direction on the exposure table 19 . The filter 8 is used to change the light transmission characteristics according to the sensitivity characteristics of the microcapsule paper 37 and adjust the color tone of the copied image.

The lens 9 is attached to a lens mounting plate 10, and allows minute angle adjustment with respect to the optical path.

On the other hand, the microcapsule paper 37 is in the form of a roll paper, and is housed in the cartridge case 13 in a state where it is supported by a shaft 14, and one end of the microcapsule paper 37 is attached to the cartridge case 13.
from the feed roller 15. It is guided by a guide roller 17 to the exposure table 19, further passes through a pressure developing device 20, and then is transferred to a peeling roller 23 and a meandering adjustment roller 24.
After being guided to the winding shaft 25, it is wound up onto a winding shaft 25. The unexposed microcapsule paper 37 after leaving the cartridge 13 is maintained in an unexposed state by the light shielding cover 16. Furthermore, since the transport speed of the microcapsule paper 37 is controlled to be constant by the capsule paper feed roller 22 and is made to match the moving speed of the document platen glass 2, the transport speed of the microcapsule paper 37 when passing through the exposure table 19 is controlled to be constant. A latent image of a predetermined line of the document is sequentially formed on the document.

A developer paper cassette 32 is provided below the pressure developing device 20. The developer paper cassette 32 stores developer paper 38, which is a paper-type image recording paper. After being conveyed by the colored paper roller 33 and having its leading end aligned by the color developing paper roller 34 and the registration gate 35, the paper is fed into the paper inlet of the pressure developing device 20. Therefore, microcapsule paper 37
The latent image forming surface of the color developer paper 38 and the color developer coated surface of the color developer paper 38 are sandwiched between the small diameter roller 21 and the backup roller 31 of the pressure developing device 20, and the unexposed microcapsules are destroyed by this pressure. As a result, an image is formed on the developer paper 38. The microcapsule paper 37 and color developer paper 38 that come out of the pressure developing device are transferred to the capsule paper feed roller 22.
After being separated by the peeling roller 23, the color developer paper 38 is sent to a heat fixing device to promote color development, and is then delivered to the paper discharge tray 27. Heat fixing device is heater 3
It is composed of a hollow heat roller 29 having a 0 inside and a color developing paper feed roller 28.

Next, the structure of the color developing paper cassette 32 mentioned above will be explained with reference to FIGS. 1 and 3.

A polyethylene terephthalate (PET) sheet is pasted on the inner surface of the outer frame 201 of the main color developer paper cassette 32 on the side where the main body of the photosensitive pressure-sensitive copying machine is installed, and a sheet of polyethylene terephthalate (PET) is attached on top of the sheet. nylon mesh 2
02 is attached.

A closed-cell foamed polyethylene sheet 203 is pasted on the left side of this surface. A mounting table 204 is provided on the bottom surface of the developer cassette 32 on which the developer paper 38 is placed. This mounting table 204 is attached by screws 221 so as to be movable in the directions of arrows A and B shown in the figure. A presser plate 205 is attached perpendicularly to the mounting table 204 on the right side of the mounting table 204 with respect to the net 202 . A closed-cell foamed polyethylene sheet 206 is pasted on the inside of this presser plate 205. Further, a knob 207 is attached to the outside of this presser plate 205. This knob 207 passes through a hole 208 provided in the outer frame 201 and projects outside the outer frame 201. By moving this knob 207, the user
It is possible to move the holding plate 205 and the mounting table 204 in the directions of arrows A and B in the figure. This knob 2
07 is provided with a 60° notch 209 on the right side in the figure. Further, cams 210 and 211 protrude from the left side of the mounting table 204 in the drawing.

On the left side of the mounting table 204 in the figure, a presser plate 212 is provided which is movable in the directions of arrow C and the direction of the arrow in the figure. A closed-cell foamed polyethylene sheet 213 is pasted on the inside of this temporary presser foot 212 . This presser plate 212 is provided with holes 214 and 215, and the cam 2
10 and 211 are passing through. These holes 214, 215
Cam followers 216 and 217 are provided at the lower right of the presser plate 212 and extend vertically from the base of the cam 210.
．． It is in contact with 211. As shown in FIG. 1, this holding plate is biased in the direction of arrow C in the figure by a spring 220 provided below the mounting table 204. That's why the presser foot! ii: 212 is the cam follower 216, 217
constantly moves to a position where it contacts the cam surface. That is, by operating the knob 207, the mounting table 204 and the presser plate 20
5 moves in the direction of arrow A in the figure, presser plate 21
2 moves in the direction of arrow C in the figure. Also, the mounting table 204
And when the presser plate 205 moves in the direction of arrow B in the figure,
The press plate 212 moves in the direction of the arrow.

When the knob 207 is pushed in, the width of the space surrounded by the closed-cell foam sheets 203, 206, 213 and the net 202 is the same as the paper size.

The color developing paper cassette 32 configured in this way has a knob 2.
07 is pulled toward you, the developer paper 38 is placed facing downward on the mounting table 204.

In this state, the presser plates 205 and 212 have moved outward, so the user can easily place the color developing paper 38 thereon.

Thereafter, the user pushes in the knob 207 to install the main developing paper cassette 32 into the main body. When the knob 207 is pushed in, the presser plates 205 and 212 move inward as described above, so that the bundles of color developer papers 38 are aligned, and the cut surfaces of each color developer paper 38 are aligned with the respective closed-cell foamed polyethylene sheets 203 and 206. .213 and cover with net 202. Closed-cell polyethylene foam has high elasticity and good adhesion, but has poor air permeability. Furthermore, the network 202 and PET have similar properties. Therefore, the developer paper 38 does not absorb moisture from its cut surface.

Furthermore, even if the knob 207 is attached to the main body without being pushed in due to the user's carelessness, the cam follower 218 provided on the main body comes into contact with the notch 209, and the knob 207 is automatically moved along the notch surface. pushed into.

Next, FIG. 4 shows a detailed structure of a paper feeding device for the color developing paper 38, which is equipped with the above-described suction cup 101. The suction cup 101 is attached to the lower end of an arm 102 that is suspended by a spring 110, and the arm 102 can be moved in the directions of arrows E and F by a cam 103 against the tensile force of the spring 110. It can swing in the directions of arrows G and H against the tensile force of. Also, sucker 101
It is connected to a pressure reducing means 106 by a pipe 105 on the inner surface thereof. The pressure reducing means 106 is composed of a cylinder 107, a piston 108, and a crank 109.
When 9 rotates, the piston 108 moves in the direction of the arrow 1, and the cam 102, cam 103,
The crank 109 is mechanically connected so that each moving body can move at a predetermined timing.

The operation of the paper feeding device constructed in this manner will be explained using FIGS. 4 and 5. First, the rotation of the cam 103 causes the arm 102 to move in the direction of arrow E, and the suction cup 101 comes into contact with the top of the layered developer paper 38 (the state shown in FIG. 5(a)). Next, as the crank 109 rotates, the piston 108
moves in the direction of arrow 1, the inside of the cylinder 107 becomes negative pressure, and the gap between the suction cup 101 and the topmost paper of the color developer paper 38 becomes negative pressure, and the color developer paper 38 is sucked into the suction cup 101 (Fig. 5 (b).
)). Next, the arm 102 is moved in the direction of arrow F by rotation of the cam 103 while keeping the gap between the suction cup 101 and the developing paper 38 negative and positive. At this time, the topmost sheet of the color developing paper 38 is sucked by the suction cup 101 (FIG. 5(C)).

At this time, the second and subsequent sheets are also pulled upward by the negative pressure, but since the friction coefficient of the net 202 is high, the second and subsequent sheets are rarely lifted.

Next, the arm 102 is swung in the direction of arrow H by rotation of the cam 104. At this time, since the position of the developer paper 38 is regulated by the developer paper cassette 32, the developer paper 38 at the top
8 causes deflection.

Through this process, even if the second and subsequent sheets are lifted without being separated, a gap is created between each developing paper 38 and the sheets are separated (FIG. 5(d)). Finally, the arm 102 is connected to the cam 104
As a result of the rotation, the color developer paper 38 swings in the direction of arrow G, and only the uppermost sheet of color developer paper 38 is conveyed to the position of the color developer paper feed roller (FIG. 5(e)).

The paper feeding unit performs a series of operations (FIGS. 5(a) to 5(d)) every time a paper feeding signal is received from the main body of the copying machine 40.

Although this embodiment has only described a copying machine that forms a latent image by using a lens to form an image of reflected light from an original onto light-sensitive and pressure-sensitive paper,
Needless to say, the present invention can be applied to image forming apparatuses using other photosensitive and pressure-sensitive papers.

[Effects of the Invention] As described in detail above, by using the present invention, there are excellent effects such that sheets can be easily stored and the positioning of each sheet can be easily performed.
