A fixing section 21 that performs fixing processing is provided.

Incidentally, since each of these parts is the same as the conventional one, detailed explanation thereof will be omitted.

In the present invention, the supply section 20 of the second recording medium 18
A kicking roller 28 is installed in place of the conventional soccer ball 25, and each rotation of the kicking roller 28 takes out the second recording medium 18 one by one from the storage section 24. Rollers 22a, 22b
It is designed to be drawn into the running path 19 by.

The developed second recording medium 18 is returned to the supply section 20 for the second recording medium 18 and the second recording medium 18 is fed again.
A return path 29 for sending the second recording medium 18 to the path 19 of the second recording medium 18 is connected to the path 19 of the second recording medium 18 . This return traveling path 29 is a pair of feed rollers 30a, 30b, 3.
0c, 30d.

It is formed by alternately arranging two parallel guide plates 30e and 30f, and is curved with a small curvature in order to make the second recording medium 18 run smoothly.

The return traveling path 29 is the traveling path 1 of the second recording medium 18.
A guide portion 32 as shown in FIG. 2 is provided at a location where the guide portion 9 branches off. Additionally, feed rollers 22e and 22f are newly provided on the travel path 19 side.

In FIG. 2, reference numerals 33a and 33b indicate guide plates arranged vertically in parallel, and these guide plates 33a and 3

A coil spring 39 that constantly pulls b is connected.

Therefore, when the solenoid 37 is not operating, the guide plates 33a and 33b are at the solid line position and the second recording medium 1
However, when the solenoid 37 is activated, it rotates to the chain line position and connects the running path 19 of the second recording medium 18 with one return running path.

In FIG. 1, reference numeral 40 indicates a sensor for detecting the position of the second recording medium 18 that has returned to the supply section 20 through the return path 29. When the sensor 40 detects that the second recording medium 18 has returned to the initial position of the supply section 20, the halogen lamp 40 is turned on to expose the next original image.

Next, the operation of the image recording apparatus will be explained.

The first recording medium 11 is intermittently fed from the paper feed roll 12 to the take-up roll 13 and seemingly stops at the exposure table 10. Meanwhile, the original 3 moves together with the original table 1, and line exposure is started by the halogen lamp 4 emitting light. Then, the image of the original 3 is copied as a latent image onto the first recording medium 11 in contact with the exposure table 10.

Further, one sheet of the second recording medium 18 is pulled out from the second recording medium 18 supply section 20 by a kicking roller 28 and feed rollers 22a, 22b, and is introduced into the running path 19 and runs.

Then, the portion of the first recording medium 11 on which the latent image is formed overlaps with the second recording medium 18 and reaches the pressure developing section 16, where the dye precursor in the microcapsules of the latent image is developed. The image is caused to appear on the second recording medium 18 by reacting with the agent.

Thereafter, the first recording medium 11 is wound onto a take-up roll 13.

In this case, when the simple copy button bt is pressed, the guide section 32 is at the solid line position in FIG. After being thermally set there, it is ejected to the ejection tray 27, and the copying of the image of the original 3 is completed.

However, when the multiple copy button b2 is pressed, the guide portion 32 is rotated to the chain line position in FIG. ? ! Processed second recording medium 18
is guided toward the inside of the return travel path 29 without being fixed. The second recording medium 18 then returns to the supply section 20 through a return path 29 .

On the other hand, another image to be combined is sequentially exposed and formed as a second latent image on the first recording medium 11 following the aforementioned image, and then moved toward the pressure developing section 16 .

Then, the second recording medium 18 that has returned to the supply section 20 reaches the pressure developing section 16 synchronously with the second latent image portion of the first recording medium 11, and the second image is developed.

Thereafter, third, fourth, . . . latent image processing and development processing are performed in the same manner, and a desired number of original images are developed on − sheets serving as the second recording medium.

When all the images are combined, the guide section 32 is switched and the second recording medium 18 is guided toward the awn section 21, subjected to a regular process, and then ejected from the apparatus.

The present invention is not limited to the embodiments detailed above, and various changes can be made without departing from the spirit thereof.

For example, instead of the kicking roller 28, a soccer ball 25 may be used as in the conventional case.

Furthermore, instead of the solenoid 37 used as a rotating means for the guide portion 32, a link mechanism including a cam or the like may be used.

Furthermore, the return path 29 may be constructed by combining an endless belt instead of the roller 30 and the guide plate 31.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, one sheet of the second recording medium can be repeatedly sent to the developing section without any predetermined processing. It is also possible to lay out and copy images from other documents.

In addition, since the guide part can be switched as appropriate, -
It is also possible to copy one original image onto a single sheet, making it an extremely practical image recording device.
