Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides page-bound manuscripts such as books! Relating to a copying machine capable of copying.

At present, there are copying apparatuses of this type (J1) using an indirect dry electrophotographic method based on an electrostatic recording method and an indirect dry electrophotographic method using an indirect acid liquid electrophotographic method.

However, in the former method, an image is exposed to a uniformly charged electrophotographic photosensitive layer, and a latent image is formed by changing the internal charge density.
This method uses a so-called development process in which fine powder toner is triboelectrically charged and adhered by Coulomb force to form an image, and then transferred onto ordinary recording paper.
The process of exposure, development, and transfer is required, and therefore the apparatus has to be large and stationary, and it also has the disadvantage of being expensive. On the other hand, the latter Gj is becoming more popular because it is relatively compact and inexpensive, but in principle it is still an indirect type that includes the steps of exposure and fixing, and structurally there is no mirror inside the device. Since it includes heavy objects such as optical systems such as lenses, photosensitive drums, and heat rollers, it is not possible to reduce the weight of &: to the extent that it is made into an iJ transportable type.
Like the former, it has no choice but to be a stationary type.

The present invention 6j eliminates such drawbacks in current devices,
The present invention provides a copying device that is light and small enough to be used as a librarian type copying device.

Therefore, the copying apparatus Gj according to the present invention includes a dot-type document reading section that scans along the document surface and a fixed arrangement I with respect to the document surface.
The main feature is that the dot-type document reading section and the dot-type recording section are electrically directly connected to each other.

In carrying out the present invention, the original surface and the recording paper are arranged parallel to each other, and a scanning port "moving rod" that slides between them is provided, and a dot type is provided at the part of this driving rod that faces the document surface. It is desirable to provide a dot-type recording section in a portion of the document reading section that faces the other recording paper.

Further, in this case, it is preferable that the dot type document reading section is a contact type image sensor and the dot type recording section is a discharge destruction type multi-stylus.

In the case of a contact type image sensor, since no lens or the like is interposed between the image sensor and the document surface, the /JXJ conversion is more important.

An embodiment of the present invention will be described below based on the drawings. 1st
Figure Gj shows a schematic side view of the copying machine.
3) is placed in close contact with. As a material for the transparent frame (3), a transparent glass plate or a plastic sheet or the like is used. (4) is a recording paper rolled out of the roll (5) and fixed on the bottom surface (6) of the main body of the apparatus.

This recording paper (4) and the original surface (2)! j are in a fixed arrangement relationship, and it is generally desirable that -j be placed in a parallel relationship as shown. The reason is that the recording paper (4) and the original m side (2
) are not placed in a parallel arrangement, the document surface (2
) along the recording paper (4).
), a separate scanning drive unit is required for each dot-type recording unit to scan along the dot-type document reading unit. The dot-type recording section can be provided on the same rod that slides between the recording paper and the document surface, and therefore only a single scanning drive section is required. The number of materials differs depending on the type of element used in the dot recording section, which will be described later. In the case of a dot-type recording unit that prints (images are formed) by discharge destruction, such as a discharge-destruction multi-stylus, etc. n is used.On the other hand, when a thermal head is used as the dot type recording section, number = G as the recording paper;
I thermal recording paper is used.

In addition, in the case of a method in which ordinary recording paper is used as the recording paper and a transfer medium is superimposed on it for recording, Gj, and in the case where the dot-type recording section is a discharge destruction type multi-stylus &j, in which a discharge transfer film is used as the transfer medium and the dot When the recording section is a thermal head, a thermal transfer film may be used as the transfer medium.

+71 GJ A dot-type original reading section scans along the original surface (2), and (8) is a dot-type recording section that scans along the recording paper (4). In this embodiment, the GJ original screen 21 and the recording paper (4) are placed in parallel.
In between, there is provided a scanning arm (9) that slides in a direction parallel to the paper surface, and a dot-type document reading section (7) is installed at the part of this arm (9) that faces the document surface (2). A dot-type recording section (8) is provided at a portion facing the recording paper (4).

A contact type image sensor can be used as the dot type document reading section (7). However, there are other examples such as OO
A D% line image sensor or the like may also be used. However, since the contact image sensor is smaller due to the lack of a lens system, it can be said to be preferable in terms of downsizing the copying device. A destructive multi-stylus or a GJ thermal head can be used. In this embodiment, the former is used. 7&) (7b) (70)
. . . It has a structure in which a large number of recording elements are arranged in a line, and the dot type recording section (8) also has dot recording elements (Z&) as shown in the same figure.
! r1) (J'o)... It has a configuration in which many are arranged in a line. And dot reading element (7 &) (7b)...
・and dot recording element Clr&> (fb)... and (
” electrically connected. When electrically connected directly, G-J is read by the reading element and the light is
The converted electrical signal is subjected to electrical processing such as amplification and waveform shaping, but it is applied to the recording element as it is without converting it into another physical 1lit.

That is, it refers to a direct recording method that does not require an intermediate development process like current copying machines.

Note that when a character, etc. is read by a reading element, the electrical signal becomes an image, so if each reading element is electrically connected to the recording element located vertically below it, a Gj lock is generated on the recording paper. The image will be recorded. For this reason, each reading element and unfinished recording (j (&) Cb shown in the figure) (0
)... is connected by ps.

Next above? The copying operation by the II copying device will be explained with reference to FIG. (a), (b), and (Q) in the same figure show the scanning of the 4-p reading section (7), and (d) (.) (fE recording section (8). First, the reading section (7) When I approached the beginning of the black letters 1yu1 written on the IK surface (Fig.
), the reading element (7f) senses the black color of the character 1'.

1 This sensing signal GJ is immediately transmitted to the recording section (8), activates the corresponding recording element (11>), and marks one black dot on the recording paper.

Next, the reading section (7) is scanned in the direction of the arrow, and the reading element (7) is scanned in the direction of the arrow.
When b) and (7f) sense the black color of character 1', the corresponding recording elements (b) and (f) operate to print two black dots on the recording paper. The gauze reading section (7) is shown in Figure (b).
) and all of the reading elements (7b) to (7f) detect black color, the recording tags (zab) to (J'f) corresponding to those elements are activated and the reading elements (7b) to (7f) are activated to read the image on the recording paper. 5
Mark all black points in a straight line. Thereafter, in the same way, i of the reading section (7)
II! If any of the reading elements (7a) to (7g) detects black color in conjunction with II, the recording elements <rh> to <Ig) corresponding to the reading element are activated to mark a black dot on the recording paper. .

Therefore, if the scanning rod (9) moves by the length of one character ``U'', the character 4J ``U'' will be recorded as a normal image on the recording paper. In the diagram, the copying operation is explained using the characters ゝY' for the sake of convenience, but any other characters, figures, codes, etc. are recorded in the same way as above. It is assumed that characters are recorded as a set of points, but in reality, as long as the reading element detects black color during scanning, the recording element continues to operate, so it becomes a line instead of a set of points. Therefore, the characters 1:L' that are identical to those written on the surface of the recording paper &:wotsu original are recorded. Furthermore, if the dot reading element and the recording element are made sufficiently small compared to the size of the characters, the recorded characters can be made more similar to those on the original surface.

Since the copying apparatus according to the present invention is configured as described above, it has the following effects.

■ Because it is a so-called direct recording method that enables copying by directly electrically connecting a dot-type yX reader that scans along the document surface and a dot-type recording section that scans along the recording paper, the current There is no need for complex processes like a copying machine, and there is no need for heavy items such as heat rulers or photosensitive drums. Therefore, the copying device can be made lightweight and significantly smaller, and if handles or the like are provided at both ends of the copying device, it can be easily carried by a single person.

Further, in this case, if a contact type image sensor is used as the dot type document reading section as in the embodiment, further miniaturization can be achieved.

■ Since parts such as heat rollers and drums are no longer required, a significant reduction in cost can be expected, and combined with the advantage of ■, it can be said to have extremely high practical value.

■Current device G'' cannot be duplicated because it takes time to preheat even when the power is turned on, but the device of the present invention has parts that require preheating. Since it does not include an S device, you can start copying immediately.However, the copying performance is also improved by using sufficiently small dot reading elements for the dot-type original reading section and dot recording elements for the dot-type recording section.
It can be improved to the same level as the current equipment.

Note that the present invention is not limited to the 111I configuration of the above-described embodiments, but includes various aspects within the technical scope of the present invention. 11N out of such l1m
enumerate.

(1) Roll the 6j note paper (4) on the actual road Tsuba (5)
Although the recording paper is unrolled from the cassette, it is also possible to prepare a cassette containing sheets of recording paper in advance.

(2) Copying is completed by the forward movement of the Ij'wJ moving rod, so if you are at work, make sure that the backward movement does not occur unless the next copying command is issued, so that other documents can be picked up during the backward movement. ◇ (2) Mechanically or electrically scan the four-door document reading unit and the dot-type trowel in a direction perpendicular to the scanning direction. In the case of mechanical scanning, the dot-type original reading section and the dot-type recording section each need one dot reading element and one recording element, which are scanned by a high-speed motor and a U cylinder in a direction perpendicular to the scanning direction.・When using electric lead yanning, the dot-type document reading section and dot-type recording section should be constructed by arranging a large number of dot reading elements and dot recording elements in a line as shown in the diagram. , Insert a switching element into the connection line (a) (b) (6) between the dot reading element and the dot recording element, and turn on and off the elements one by one from one end to the other in order over time. All you have to do is go as you go.
