Abstract

PURPOSE:To obtain a device which is small-sized and has high resolution, by placing an original on an original placing plate, and a 1 line type display, on one side of a 1 line type self-focus lens, so that they can be selectively opposed. CONSTITUTION:On one side of a 1 line type self-focus lens 1, an original on an original placing plate 2, and a 1 line type display are placed so that they can be selectively opposed. In this state, when the original placing plate 2 moves in the direction as indicated with an arrow (d), its original 13 is irradiated by a 1 line type light source 12, its reflected ray is irradiated by the 1 line type light source 12, and its reflected ray passes through the 1 line type self-focus lens, by which the original is charged, and on a photosensitive drum 4, a latent image of the original 13 is formed. According to such a constitution, a device which is small-sized and has high resolution can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Conventional image processing apparatuses include copiers, printers, and document readers, each of which is a single device, and will be briefly described below.

First, a single copier, particularly a xerography-type copier using plain paper as recording paper, will be explained.

Using a photoconductive drum such as selenium, the narrow surface of the drum is charged, and the light from the cool yuzu is focused on it with a lens.
2. Discharge the electrical charge on the drum according to the intensity of the light,
The original image formed on the adhesive surface of the drum is visualized by sprinkling toner onto the circumferential surface of the drum by a toner supply means serving as a measuring means. Toner adheres to the charged parts of the drum and does not adhere to the uncharged parts, so an inverted image of the original appears on the drum.The image on the adhesive side of this drum is used as recording paper. Transfer to paper,
By passing this recording paper through a heat roller serving as a fixing means, a copy of the original document is formed on the recording paper.

Next, the printer will be explained. The printer uses the above-mentioned copier principle, but uses a helium-neon laser or an optical fiber tube as the print head instead of the original.The laser uses a rotating polygon mirror to deflect the light emitted from the print head, and the optical fiber The tube guides light through its fibers, and each lens focuses the light onto the photoconductive drum to form a KfW image on the drum.The subsequent process is similar to that of the copier described above.・
Next, the document reader will be explained. The light from the document is focused by a lens, and an image is formed on a one-line VCCD or an amorphous silicon one-line sensor, and the intensity of the light is converted into an electrical signal.The electrical signal is then stored in a memory.

Now, each of the above-mentioned devices is a stand-alone copier, printer, and document reader, but if you look at these devices, there are some parts that can be shared. There is a great possibility◎Therefore, the common parts of these devices can be used in the same way,
An iliigl processing device can be considered that has the functions of a copier, a printer, and a document reader in one device.

In addition, since the above-mentioned printers used optical fiber tubes or helium-neon lasers as mentioned above, these printers had the following drawbacks:
Those that use optical fiber tubes have the disadvantage that the tube itself is large, heavy, and thin, and the resolution is not very good. In addition, in those that use a laser, a rotating polygon mirror is required to deflect the light, and a long optical path is required as well as Nf[] precision and rotational precision of 7, and the fruiting device is large and large. It becomes weight,
Price increases cannot be avoided either.

In view of these points, the present invention combines the functions of the above-mentioned copier, printer, and document reader, has a simple and compact overall configuration, can reduce weight, and moreover reduces the sum of the prices of the three devices. The aim is to propose a product that is lower in price than the previous model.

In the image processing apparatus according to the present invention, a one-line self-focus lens is arranged such that an original on a document table and a one-line display can selectively face each other on one side, and a photosensitive drum and a one-line display are arranged on the other side. It is made up of two types of lights arranged so that they can selectively face each other.

An embodiment of the present invention will be described below with reference to FIG.
(1) It is a hull line type self-focus lens. On the negative side of the one-line self-focus lens (1), a one-line display (3) is arranged so that it can selectively face the original on the original platen (2). This original table (2) is made of a transparent plate such as a glass plate, and is movable in the direction of the arrow a or in the direction of the arrow a. For example, on the left end of this document table (2)
Line display (3) is KJG! It is attached. For example, a plasma display can be used as this 1-line display (3), but an individual light emitting diode array, electroluminescence, etc. can also be used.
) is arranged so that the i-sensitive drum (4) and the one-line optical sensor (5) can selectively face each other. As this photosensitive drum (4), a photoconductive drum made of amorphous silicon or the like is used. This drum (4) is rotatable, for example, in the direction of arrow d. 1 line type Hikari Seven Sensor (5)
For example, amorphous silicon or the like can be used. In this example, is it a one-line optical sensor? (5) is integrally attached to a part of the photosensitive drum (4) so as to extend in the direction of its generatrix. It is made to come into contact. Charging means (7) is arranged near the drum (4) and uses, for example, a corona discharger. (8) is a current dispensing means provided near the drum (4), and uses, for example, a toner supply device. (9) is a fixing means, and uses a heater roller, for example. Q is a one-line light source, and uses a fluorescent lamp, for example. This light source may be fixed or movable.In this embodiment, a one-line self-focusing lens (
1), 'A one-line optical sensor (5) and a one-line light source a4 extend in a direction perpendicular to the paper surface.

The wire is a memory, and the light from the 1-line optical sensor (I
This is to memorize the t number. In this memory θ, an optical disk recorder, a magnetic data recorder, etc. can be used. The successive output of memory α [yop] is displayed on the display (
3) K supplied @aυ goes to external interface 7e 0 External interface (signal from υ goes to memory Ql and 1 line/type display (31K supplied ◎ This image processing koji is used for copiers and printers as mentioned above) , which can be used as a document reader.Firstly, the case where this image-processed koji is used as a copier will be explained with reference to Figure 1I.Original table (2)
The original stage α is placed above. The photosensitive drum (4) is rotated, for example, in the direction of arrow d.

Then, when the document table (2) moves in the direction of arrow a, the document 0 is illuminated by a one-line light source QaK, and the reflected light passes through a 12-inch self-focusing lens.
Therefore, the light is linearly focused onto the photosensitive drum (4).

Since the photosensitive drum (41 * * t) is charged by the means (7) K, the charges on the photosensitive drum (4) are discharged according to the intensity of the light, and the charges on the photosensitive drum (4) are discharged. A latent image is formed on the original document a. When the formation of this latent image is completed, the toner from the developing means (8) is uniformly sprinkled onto the cylindrical surface of the photosensitive drum (4). In the area where the toner is exposed to the photosensitive drum (
4) Toner does not adhere to the surface of the photosensitive drum (4) where there is no charge ◎Thus, on the cylindrical surface of the photosensitive drum (4), the original <13
1 is formed. This inverted image is transferred onto a recording paper (6) made of plain paper, the transferred image is heated by a fixing means (9) K, and the toner is, for example, carbon and heat-fusible resin, so recording paper (
6) Although not shown, after the above-mentioned process is completed, the toner adhered to the drum (4) is removed by cleaning means to prepare for the next copying. 1 The operation when this image processing apparatus is used as a printer will be explained with reference to FIG. In this case, the 1-line display (3) moves above the 1-line self-focus lens (1).
◎The document is not placed on the document table (2), and the document table (2) remains fixed. The photosensitive drum (4) rotates in the same way as the copier in Figure 1.
is electrically charged, and the light from the one-line display (3) is focused linearly through the one-line self-focus lens (1) [4, photosensitive drum J-! (4) irradiated on top. This one-line display (3) is supplied with signals from the external interface aυ or the main frame, so drawings, characters, etc. corresponding to the signals are recorded on the photosensitive drum (4) as text. In this case, the light source (I) is printed on the recording paper (6) in the same way as in FIG.

Next, with reference to FIG. 3, the case where this image processing apparatus is used as a document reader will be explained. In this case, the document α is placed on the document table (2), and
is assumed to move in the direction of arrow a. In this case, the photosensitive drum (4) does not rotate and the one-line optical sensor (5)
) is fixed under the 1-line self-focus lens (1), and when the document table (2) moves, the light from the document passes through the 1-line self-focus lens (11K).
Therefore, the electric signal from the one-line optical sensor (5) is focused linearly and irradiated to the one-line optical sensor (5) and stored in the memory α (IVc).

In the above embodiment, the case where the L-type optical sensor (5) was formed integrally with the photosensitive drum (4) was described, but it may be formed separately from the photosensitive drum (4). Also, l
Although the line type display (3) is formed integrally with the document table (2), it may be formed separately from the document table (2). Also, manuscript table +
21 ii This is the case where the document α is moved in the direction a when placed on it, but this document table (2) is fixed and the document is placed on the document table (2) using a low 2 fathom. Pressure may be applied to move the top.

In addition, to describe an application example, three colors such as cyan, magenta, and yellow are placed in front of a single-line self-focus lens (1).
By installing color filters and using three-color toners such as cyan, magenta, and yellow, it is possible to configure an image processing device that also has the functions of a color copy, color printer, and color document printer. ◇ It is also possible to connect a keyboard, CRT display, and personal computer to the external interface aυ to configure an advanced office automation system. Because it uses a 0- or 1-line type display, you can obtain an image processing device that also has the functions of a copier, printer, and document printer (copier, printer, and document printer) at a low price.
Optical 7A allows the device to obtain fine wrinkles and high resolution compared to those that use an ipertube laser.
