Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic printing device, and an object thereof is to provide a multipurpose electronic printing device that can perform a copying function, a sending function, and a receiving function independently or simultaneously. This is what we are trying to provide.

An embodiment of the present invention will be described below based on FIG. In the figure, reference numeral 1 denotes the main body of an electronic printing device, and a drum-shaped photoreceptor 2 is installed approximately in the center of the main body 1. Around the photoreceptor 2, a charging charger 3,
A focusing photoconductor 5 of an exposure device 4, a developing device 6, a transfer charger 7, and a cleaning device 8 are arranged. Additionally, a photoreceptor 2 is provided on the top surface of the main body 1.
A movable document table 9 is provided which moves forward and backward at a speed equal to the circumferential speed of the document table 9, and an exposure lamp 10 for irradiating the set document A is provided near the bottom surface of the document table 9. Further, at the inner bottom of the main body 1, an electrostatic recording paper _P1 sent out via a paper feed roller 12 from a paper feed cassette 11 as a paper feed section mounted on the left side of the main body 1 is placed between the transfer charger 7 and the photosensitive member. The main body 1 passes through the transfer section 13 between the main body 2 and the main body 1.
A paper conveyance path 15 leading to a tray 14 mounted on the right side of the paper is formed. A fixing device 16 is arranged at the end of the paper conveyance path 15.

A copying function generating section 17 is configured.

Further, in the vicinity of the exposure device 4, a reduction optical system 2 is provided which includes a mirror 19 and a lens 20 that guide reflected light from the original A to the solid-state image sensor 18.
1 is arranged to constitute the transmission function generating section 22.

Furthermore, a multi-needle electrode 23, which is a multi-point combination pattern forming means, is arranged on the starting end side of the paper transport path 15, and the developing device 6
Of the two magnetic developing rollers 24 and 25 that can rotate independently or simultaneously, the lower developing magnetic roller 25 faces the paper conveyance path 15 and constitutes a receiving function generating section 26.

Next, the copying process will be explained. First, when a copy button (not shown) is pressed, the photoreceptor 2 begins to rotate counterclockwise, and an electric charge is placed on the surface of the photoreceptor 2 by the charging charger 3. Next, in synchronization with the rotational movement of the photoconductor 2, the document table 9 starts to move forward, and the exposure lamp 10 is lit for a long time to illuminate the document A, so that the reflected light becomes convergent light having a lens function. A slit is exposed to the surface of the photoreceptor 2 at the same magnification through the conductor 5. Therefore, an electrostatic latent image is formed on the surface of the photoreceptor 2 by eliminating the charge on the surface where the light hits.

Next, this electrostatic latent image faces the developing device 6 and comes into sliding contact with a magnetic brush made of a one-component developer formed by the upper developing magnetic roller 24, and the developer adheres to the electrostatic latent image. A visible image is formed.

On the other hand, in synchronization with the operation of forming a visible image on the photoreceptor 2, the electrostatic recording paper _P1 is fed from the paper feed cassette 11 into the paper transport path 15 and passes through the transfer section 13. At this time, due to the function of the transfer charger 7, the photoreceptor 2
The visible image formed on the surface of is transferred to electrostatic recording paper _P1 . Next, the paper P ₁ ' onto which the image has been transferred is smoothly conveyed to the tray 14 side, and during this conveyance, the visible image is fixed by the fixing device 16.

Next, to explain the transmission process, the reflected light from the original A is projected onto the solid-state image sensor 18 via a reduction optical system 21 consisting of a mirror 19 and a lens 20, photoelectrically converted, and transmitted to others. . Note that by applying this signal to the multi-needle electrode 23, recording may be performed on the electrostatic recording paper _P1 while changing the magnification.

Further, to explain the reception process, an electric signal sent by facsimile or an output signal from a computer is converted into an electric signal that can be applied to the multi-needle electrode 23 and applied. Thus, an electrostatic latent image is formed on the electrostatic recording paper _P1 , which is developed by the lower developing magnetic roller 25 of the developing device 6, and sent to the fixing device 16 through the transfer section 13 to be fixed. become. At this time, the transfer charger 7 is turned off so as not to adversely affect the image quality.

In addition to performing each of the above processes independently, we can also perform simultaneous operation of the copying process and the sending process.
The sending process and the receiving process may operate simultaneously, the receiving process and the copying process may operate simultaneously, or the three processes of the copying process, the sending process, and the receiving process may operate simultaneously.

In addition, in the above-mentioned embodiment, electrostatic recording paper
Although I decided to use only P ₁ , it is not limited to this.
As shown in Fig. 2, a paper feed cassette 27 containing plain paper _P2 is arranged below the paper feed cassette 11 containing electrostatic recording paper _P1 , and during the copying process, inexpensive plain paper P is placed. ₂ may be supplied.

In addition, it goes without saying that the present invention is not limited to the above-described embodiments, and that various modifications can be made without departing from the gist of the present invention.

In the description of the other embodiment described above (FIG. 2), the same parts as those of the above-mentioned embodiment will be given the same reference numerals and the explanation will be omitted.

As explained above, the present invention includes a copying function generating section using an electrophotographic method, a receiver generating section using a multi-point combination pattern, and a transmitting function generating section using a photoelectric conversion method, each of which can be used alone or in multiple combinations at the same time. Since it is made operational, it is possible to efficiently process many types of information with a single device, and it is also possible to superimpose image information and electrical signal information. In addition, since a receiving function generating section that writes an image on paper using a multi-point combination pattern is arranged between the paper feeding section that feeds paper to the copying function generating section and the copying function generating section, Compared to the case where it is built in, there is more space available in the copying function generator, and the assembly, maintenance, inspection, and repair can be carried out extremely easily.
