The present invention provides a copying apparatus that moves to form a mirror image of the original image on the image carrier, and then moves over the transfer material to transfer the mirror image onto the transfer material. be.

[Example of idea]

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 2 is an external perspective view of the copying apparatus 1 of the present invention. The copying device 1 is provided with a power switch 2 and a switching button 3 for switching between reading and printing, and the switching button 3 can be moved in the direction of the arrow shown in the figure. sometimes copying machine 1
is in a state in which it reads the original image, and when it is moved downward, it is in a state in which the read image is printed at a desired location.

By operating this switching button 3,
It is configured such that when the internal electric circuit is switched, some mechanical parts move in conjunction with the movement of the switching button 3, as will be described later. FIGS. 3a and 3b are perspective views for explaining the operating method when actually copying.

First, operate the above-mentioned switching button 3 to put the copying device 1 into the reading state, place it on the original to be copied (for example, newspaper 4), and use the means to move the copying device 1 in the direction of the arrow shown in FIG. 3a. move it.
When the copying device 1 passes over the image to be copied,
The above-mentioned switching button 3 is operated to put the copying apparatus into a printing state. Next, the copying device 1 is placed at a place where the copied image is to be printed (for example, on the notebook 5), and as shown in FIG. 3b, the copying device 1 is moved in the direction of the arrow shown in the figure.

With the above operations, the above newspaper 4 will appear on Note 5.
A copy image 6 of the image desired to be copied is printed.
FIG. 1 is a sectional view of a main part of such a copying apparatus 1. As shown in FIG. Inside the casing 11 having an opening at the bottom,
A light source lamp 12, an imaging lens array 13, an image sensor 14, an image carrying belt 15, an inkjet head 18, a sub-scanning roller 19, etc. are provided. The sub-scanning roll 19 is a roll having a high-friction member such as rubber coated on its circumferential surface, and is driven to rotate by moving the copying device 1 over the newspaper 4 or notebook 5 described above. Further, the sub-scanning roll 19 is connected to a support roll 17 as will be described later, and is further connected to a pulse generating means (not shown) that generates a clock pulse at every predetermined rotation angle of the sub-scanning roll 19.

The image bearing belt 15 is stretched between support rolls 16 and 17, and the speed of the peripheral surface of the support roll 17 (more precisely, the peripheral surface of the stretched image bearing belt 15) is higher than that of the peripheral surface of the sub-scanning roll 19. It is connected to the sub-scanning roll so that the speed is the same as that of the sub-scanning roll. The image carrying belt 15 and support rolls 16 and 17 are movable as a unit, and when the above-mentioned switching button 3 is operated to read the document, they are in the position shown by the solid line in the figure, and when the switching button 3 is operated to the printing state. When operated, the circumferential surface of the image carrying belt 15 is in a position protruding downward from the opening at the bottom of the casing 11, as shown by the broken line in the figure.

In the document reading state, the light source lamp 12 is turned on, the image sensor 14, which is a line image sensor of equal magnification type, becomes operational, the inkjet head also becomes operational, and a pulse generating means (not shown in detail) is also activated. Pulses can be generated. When the copying device 1 is placed on the above-mentioned newspaper 4 in this state, the image on the newspaper is illuminated by the light source lamp 12, and the reflected light from the image is reflected by the imaging lens array (product name: self-occurring lens array) 13. An image is formed on the image sensor 14 by.

When the copying apparatus 1 is moved as shown in FIG. 3a, the sub-scanning roll 19 starts rotating as it moves, and a pulse generating means (not shown) generates a pulse at every predetermined rotation angle of the sub-scanning roll 19. . Each time this pulse is generated, the image sensor 14 reads the formed image and outputs an image signal for one line. In addition, in synchronization with this pulse, the inkjet head 18 discharges ink to perform one line of recording on the circumferential surface of the moving image bearing belt 15 in accordance with the output of the image sensor 14 described above.

The ink ejected from the inkjet head 18 is a slow-drying ink, and the peripheral surface of the image bearing belt is made of a material with good release properties (for example, fluororesin).
Since the ink adhered to the circumferential surface of the image carrying belt 15 does not dry out quickly or is absorbed by the image carrying belt 15.
In this manner, when the copying device 1 passes over the image to be copied on the newspaper 4, an ink image that is a mirror image of the above-mentioned image is carried on the circumferential surface of the image carrying belt 15.

Next, when the operation button is set to the print state, the image support belt 15, support rolls 16, 17 are
move as one, a part of the circumferential surface of the image carrying belt 15 protrudes from the opening at the bottom of the casing 11,
At the same time, the light source lamp 12 goes out, and the pulse generating means, image sensor 14, and ink jet head 18 also become immobile. In this state, copying device 1
When the notebook 5 is placed on top of the notebook 5 and moved as shown in FIG. Rotate in the opposite direction. At this time, a part of the circumferential surface of the image carrying belt 15 is covered with the casing 11.
Since it protrudes from the bottom of the notebook 5, it is in pressure contact with the surface of the notebook 5, and since the peripheral speed of the image bearing belt 15 and the peripheral speed of the sub-scanning roll 19 are equal, the image bearing belt 15 and the surface of the notebook 5 rub against each other. Never. Therefore, the ink image carried on the circumferential surface of the image carrying belt 15 during the above reading is transferred to the surface of the notebook 5 and permeates into the notebook 5. As a result, the correct image of the image on the newspaper 4 is copied onto the notebook 5. Further, most of the ink carried on the circumferential surface of the image carrying belt 15 is transferred to a transfer material such as a notebook 5, but a small amount of ink remaining on the circumferential surface of the image carrying belt 15 is removed by the cleaning member 20. Ru.

With the above configuration, the image of the document can be copied onto the desired transfer material by a simple operation of moving the copying device 1 over the document to be copied and then moving it over the desired transfer material.

FIG. 4a is an external perspective view showing a second embodiment of the copying apparatus of the present invention, and FIGS. 4b and 4c are side views showing the operating procedure thereof. The internal configuration of the copying device 21 is approximately the same as the internal configuration of the copying device 1 in the first embodiment described above, but in this embodiment, the image belt and the support roll are not movably provided, and the copying device is supported in a fixed position.

Further, the bottom of the casing 22 of the copying device 21 has a substantially V-shape, and reading slits 2 are provided on two inclined surfaces 22a and 22b forming the V-shape, respectively.
4 and a copying slit 25 are formed. A portion of the circumferential surface of sub-scanning rollers 26, 26 protrudes outward from both ends of the reading slit 24, and these sub-scanning rollers 26, 26 carry the image carrying belt 27 in the same manner as the above-mentioned sub-scanning roll 19. It is connected to a support roll (not shown) that supports it. Further, the sub-scanning roller 26 of the reading slit 24,
The structure is such that the image of the original is read from the portion between 26 and 26, similar to the above-described embodiment.

A part of the circumferential surface of the image carrying belt 27, which is stretched and supported by the above-mentioned support roll (not shown), protrudes outward from the copying slit 25.

When copying using such a copying device 21, first place the copying device 21 so that the inclined surface 22a is substantially parallel to the surface of the original (for example, newspaper 4) as shown in FIG. Copying device 21 in the direction of the arrow
move.

Next, the copying device 21 is placed so that the inclined surface 22b is substantially parallel to the surface of the desired transfer material (for example, the notebook 5), and the copying device 21 is moved in the direction of the arrow shown in the figure.

Through the above operations, it is possible to copy the original image onto a desired transfer material in the same manner as in the first embodiment described above.

Further, in the second embodiment, since the inclined surface 22a is moved to face the document during the reading operation, reading can be performed even without a mechanism for moving the image carrying belt 27 in conjunction with the switching operation between the reading state and the printing state. The image carrying belt 2
7 does not come into contact with the surface of the original, and the configuration can be simpler than that of the first embodiment.
