Description

[Detailed description of the invention] Industrial field of application The invention is based on the invention, in which a sheet is attached to the main body board so that it can be transferred, and the sheet is transferred and its surface is scanned with a photoelectronic sensor such as a solid-state image sensor to generate digital electrical signals. The present invention relates to a board-type electronic copying apparatus that reproduces the converted image on recording paper as a copied image.

2. Description of the Related Art Conventional electronic copying apparatuses of this type have been designed with the main purpose of copying sheet surfaces, and do not have the function of copying ordinary original paper.

Problems that the invention aims to solve With conventional methods, if you dare to copy normal manuscript paper, you can do so by pasting it onto the sheet surface, but the large scale of the copy makes it so small that it cannot be read. In the end, the actual situation was that the copies were made separately using a regular copying machine.

The purpose of this invention is to utilize the copying mechanism as it is without impairing the original function of copying the sheet surface.
Moreover, it is an object of the present invention to provide a board-type electronic copying apparatus that can copy ordinary original paper by simply adding a paper feeder and a simple optical system.

Means for Solving the Problems The board-type electronic copying device of the present invention allows manual writing on the sheet surface using a writing instrument, and
In a board-type electronic copying device that can transport the sheet as necessary, read the written content with a photoelectronic sensor, write the read content on recording paper, and send out the recorded paper after writing, what is the sheet? Separately, there is a paper feeding device that transports the original paper, and one of the sheet light from the sheet or the original paper light from the original paper is guided as it is to the photoelectronic sensor, while the optical path of the other light is changed. and an optical path changing means for guiding the light to the photoelectronic sensor.

Effect: Therefore, by switching the optical path changing means, it is possible to arbitrarily select between copying the sheet surface and copying the original paper.

Embodiments Below, embodiments of the present invention will be specifically described based on the drawings.

In FIG. 1, a white sheet 11 is attached to the main body board 10 so as to be transported along the front surface of the main body board 10 by a winding device, as in the conventional case, and a recording paper is attached to the underside of the main body board 10. A stacker 12 is attached.

The main body board 10 is also provided with an operation panel (not shown), and when the sheet feed button is pressed, the sheet 11 is transferred, and the surface of the sheet 11 is transmitted through a camera lens 13 to, for example, a CCD type image sensor 14. After being scanned and converted into a digital electrical signal, it is processed by the CPU, and a copy is printed on recording paper and sent out from the stacker 12.

In addition to such a main device, the main board 10 further includes a paper feeding device 1 for feeding normal manuscript paper.
5 and a reflecting mirror 16 serving as an optical path changing means.

As shown in FIG. 3, the paper feed device 15 pivotally supports a front feed roller 17, a main feed roller 18, and a rear feed roller 19, and has a front guide plate 20 and a rear guide plate 21 above these. A fluorescent lamp 22 serving as a light source and its cover 23 are installed above the lamp. Front and rear guide boards 20 and 2
A scanning window 24 is formed between the main feed roller 18 and the rear feed roller 19, a document feed port 25 is provided below the front roller 17, and a document feed port 26 is provided below between the main feed roller 18 and the rear feed roller 19. It is formed. A document receiver 27 is vertically provided below the document sending port 26 .

On the other hand, the reflecting mirror 16 is pivotably supported above the scanning window 24 by a shaft 28 so as to be rotatable up and down. When this reflecting mirror 6 is set at the upper position as shown in FIG.
The light from the surface of the camera lens 13 is made to enter the camera lens 13 as it is. On the other hand, when set in the lower position as shown in FIG. The light is reflected and guided to the camera lens 13.

Therefore, when the sheet 11 is transported with the reflecting mirror 16 set at the upper position, its surface is scanned and a copy is printed on the recording paper as in the conventional case.

On the other hand, with the reflecting mirror 16 set at the lower position, the paper feeding device 15 is operated, and the document feeding port 25 is operated.
When normal manuscript paper is inserted into the machine, the manuscript paper is sandwiched between the front roller 17 and the main roller 18 and sent to the scanning window 24. As it passes through the scanning window 24, the image sensor 14 scans the surface of the manuscript paper. is scanned, and a copy is printed on recording paper at a smaller scale than the sheet 11 or at approximately the original size. The original paper that has passed through the scanning window 24 is sandwiched between the roller 18 and the rear roller 19 and sent out from the original delivery port 26.
The document is held by a document receiver 27 .

In the above-mentioned embodiment, the optical path was changed by rotating the reflecting mirror 16, but as shown in FIG. Alternatively, the optical path may be changed by sliding it downward. Further, as the optical path changing means, a prism may be used as shown in FIG. Furthermore, if the CPU is provided with a function of storing the display contents of the sheet 11, the display contents and the display contents of the original paper can be simultaneously overlapped and copied and printed.

Effects of the Invention As described above, according to the board-type electronic copying device of the present invention, it is possible to copy ordinary manuscript paper without impairing the original function of copying the sheet surface. Moreover, the copying is economical because it can be performed by using the mechanism for copying the sheet surface as it is and by adding a paper feeding device and a simple optical system.
