Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention involves placing an original on a grating glass, irradiating the original surface with a lamp from below, and displaying an image of the J-Kyogu face. This invention relates to an improvement of a copying machine that can be tied to the body.

PRIOR TECHNOLOGY In the above-mentioned Enoki Iso, in an attempt to restore the f le original 'tFX'; i m , the centimeter was turned over onto the two-latin glass, and then the sword bar Z was placed over it and the photograph was taken. It is not possible to check what the resulting reproduction will be like before copying.

Particularly when copying in a reduced or enlarged manner, the size and position of the copy are of great concern, but it is important to visually check the size and location of the copy beforehand. It was not possible to do so, and the only way to confirm it was to look at the Sakura photo that came out of the photocopier after the photo was taken.

Therefore, when there are many types of wafers with various dimensions and various return magnifications, it takes a lot of effort and inconvenience to check each sheet one by one. Purpose of the present invention is to improve the above-mentioned drawbacks of conventional copying machines. It has a mouth and 7 purposes so that people can visually confirm it.

Structure of the Invention In order to achieve the above-mentioned object, in the hard drive machine of the present invention, a monitor glass is installed adjacent to the platen glass, and a t-t is placed on the platen glass. An optical system 7 is provided for sending an image from below in accordance with the magnification at which the original is to be copied.

Therefore, by looking at this monitor glass, the worker can
You should be able to visually check the condition of the duplicate that comes out in 2 tons in advance.

Example Hereinafter, one embodiment of the present invention will be explained with reference to the drawings.

1 shows the entire temporary copying machine. The upper surface of this copying machine has a monitor glass 3p2 adjacent to a normal platen glass 2. The monitor glass 3 may be made of frosted glass, or may be made so that it can be viewed with the naked eye from the optical image Z formed on the lower surface by applying a suitable coating or the like.

Reference numeral 4 denotes an original placed on the platen glass 2, and this original is read by the same device as in the prior art.

-j Tx That is, the original 4 is irradiated from below in a slit shape by the irradiation lamp 5, and the reflected light is reflected by the mirrors 6, 7, .
8 and 9 and a lens 10, an image of the original 4 is formed on the surface of the photosensitive drum 11. 8. The illumination lamp 5 and the mirror 6 move together parallel to the document and scan the surface of one document one after another. Mirror 7 and mirror 8 also follow the illumination lamp 5 and mirror 6 at half the speed.

The copying magnification can be changed by changing the horizontal distance between the mirrors 7 and 8 and the mirror 6, and by changing the position 7 of the lens 10.

As usual, a tarina is placed around the photoreceptor drum 11.
12, a charger 13, a developing device 14, and a turning device 15 are arranged, and the paper is transferred from the paper feed cassette 16 to the transfer device 1.
5, the sheet is completely transferred to the fixing device 18 by the printer 17, where the copying step Z is completed and the sheet is discharged onto the sheet discharge tray 19 as a copy.

In this embodiment, in addition to the normal close-up device described above, an optical system as described below is added according to the present invention.

This optical system consists of a first mirror 20, a lens 21, a second mirror 22, and the monitor glass 3, and is further provided with a monitor lamp 23.

This optical system is separated from other parts inside the copying machine 1 by a partition wall 24.

As shown in the previous figure, the first mirror 20 is opposed to the platen glass 2, the second mirror 22 is opposed to the monitor glass 3, and a lens 21 is located between the two mirrors 20 and 22. It is located.

The partition wall 24 includes a first mirror 20 and a platen glass 2.
An opening 2!5 is provided in the part corresponding to the optical path between 45
In addition, a shutter member 26 is provided which can appropriately cover the opening 2!5Z. The striped ivy member 26 is indicated by the arrow a
As shown in Fig. 1, the opening is opened 25 mm and the opening is 1 stiff.
The monkey is in the furnace.

Directly below the monitor glass 3 is a filter bar 27.
It is arranged so that it can reciprocate along the lower surface of the monitor glass 3 as shown by the arrow. This filter blade bar 27 is placed along each side of the monitor glass 3 in front, back, left and right.
A total of four filter bars 27 are arranged, and these four filter bars 27 work together to form a rectangular opening in the center that simulates an aquarium.

The first mirror 20, the lens 21, and the second mirror 22 are mounted on the same frame 29, and this frame 29 is movable in the vertical direction as shown by arrow C. It is attached to the main body of the copying machine. The lens 21 is mounted on a frame 29 so as to be movable in the front-back direction as shown by arrow d.

Next, the operation of this copying machine will be explained. Place the original 4 on the vibrate glass 2 that you are trying to copy.
Specify 1 paper size and 7 magnifications. The order of these operations does not matter. Installed on the upper surface of the joint 1 (Zurare L)
When the paper size is specified using the paper size key 31 on the operation panel 30, the specified line is entered;
16 is selected and 4 filter covers 2
7 is operated to form an opening 28 in the center having the same shape as the paper of the specified size.

Further, when a repeating magnification is specified using the magnification key 32 on the operation panel 30, the mirror 7.8 and the lens 10 move according to the specified magnification, and the optical system 1a returns to the specified magnification. However, at the same time, the frame 29 moves upwards and the lens 21 moves back and forth above the frame.
Then, the magnification of the monitor optical system from the Fulladen glass 2 to the monitor glass 3 cores is set to be the same as the magnification of the close-up optical system. Of course, if the copying machine has already been set according to the specified paper size and specified magnification, the operation of each part as described above is not necessary, and the same state will be maintained.

Next, press the monitor key 33, and the monitor lamp 2;
When the 7 lights are turned on, the simanta member 26 moves to the illustrated position 11 and opens the opening 25. Therefore, if the entire surface is exposed using the monitor wrap tone, the image of the original 4 will be
1st mirror 20% lens 2] 3 and second mirror 227
Afterwards, it is projected on the bottom surface of the monitor glass 3, but since the magnification is the three copying magnifications and rotation, the image Z is completely rotated compared to the copy that comes out one paper output tray above. You can see what you can see on the monitor glass 3 in advance.

T1 The image here can be seen only through the opening 28 formed by the filter cover 27 and having the same shape as the paper of the specified size, so you can confirm the position and size of the copy image on the paper, and set the original. Any mistakes or mistakes in paper selection can be made in advance.

After checking the image on the monitor glass 3, if there is no problem, press the start key 34 on the operation panel 30 to start copying Z. Then, before the lighting lamp 5 lights up,
The monitor rung 23 goes out, and at the same time the shutter part 26 operates to cover the openings 2!5. Next, the illumination wrap 5 is turned on, and copying is performed in the normal procedure thereafter.

While copying is being performed, the opening 25 is shielded by a portion of the ivy side 26, and the monitor glass is optically isolated from other parts by the partition wall 24, so that the monitor glass 3, external light enters the Enoki copying section and does not disturb the actual copying process. When the copying is completed, the stripper member 26 may open the opening 5 again.

The mirrors and lenses of the first copy source system are arranged at positions such that they do not interfere with the projection of all sides of the original 4 on the first mirror 20 at the same time as the monitor.

'f, T, the magnification of the monitor optical system, the imaging optical system θ] is one smaller than the sound rate A, and the magnification of both optical systems σ) ratio (1
For example, the images of the originals 11 and 111 reflected on the monitor glass 3 should always be half the size of the original images repeated on the paper.
Even if the filter cover 27 is controlled so that the IJ port also has a thickness K that is half the paper size, the original image relative to +14 paper can be controlled in this way. There is no problem in checking the positional relationship Z (・.

The present invention as described in ``Effects of the Invention''! When copying, especially when copying after reducing or enlarging, check the thickness and position of the image related to each sheet before copying. ○ In addition, while looking at the monitor glass Z while placing the document on the bottom of the platen glass, check the position of the document 'f-71.
