Abstract

PURPOSE:To display the toner image formed on a photoconductive belt in high displayed density without fluctuation and to make the transfer of the displayed content free by forming said image on said belt, displaying the same and transferring the displayed image according to need. CONSTITUTION:A photoconductive belt 8 consisting of a conductive material such as Al coated with an org. photoreceptor such as PVK-KN or the like is moved with a roll 22 and is formed thereon with a toner image by an electrostatic charging section 17, an exposing mechanism section 15 controlled by an information processing section 16, a magnetic brush 13 of a developing section 4, etc. When the belt 8 is stopped, the toner image is displayed in high display density without fluctuation. The displayed content is transferred freely on transfer paper 2 with a transfer roll 25.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention forms an organic photoreceptor into a belt shape, uses developed toner for display purposes, and when a hard copy is desired, the toner is printed using a transfer mechanism. Conventional technology related to display printers 5. Four different types of displays and printers have been announced and are commercially available. However, there has never been a compact display with a hard copy function that combines a display and a printer.

There was no flicker-free display that was extremely cheap, had a high display density, and did not exist.

The present invention overcomes the above-mentioned drawbacks and provides a display printer that does not cause visual discomfort even when viewed for a long period of time, can display a high density display, and has the function of freely printing the displayed contents.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is an external view of the present invention. 1 is a display section, 2

η)], 7 is a conductive layer such as Mut% iler. ￥
A negative charge is charged on the surface of the OTL as a result of a stiff discharge at the r-electrode. At this time, when the 0-order exposure is performed in which the interface side of the conductive layer with OGI is charged with an opposite positive charge, the irradiated light passes through the transparent OTL layer and reaches 0GLNAK.

At this time, the 001 layer receives the irradiation light and generates charges, and the generated charges 1jOTL move to the conductive layer and disappear, forming a latent image/bamen'1OTL according to the light irradiation pattern. Figure 3 is a vertical sectional view of the present invention. OTL
, CGL, photoconductive bell) 8 consisting of a conductive layer is rotated by a roller 22 in the direction of the arrow in the figure. The photoconductive belt 8 is charged by a charging section 17 by corona discharge. The display information sent from others is converted into an exposure pattern by the information processing section 16 and then displayed by the exposure mechanism 15.
t-Move the light emitting element to emit light onto the belt 8 K
Form l'llll. lI! I! 18 is a booster for corona discharge. The photoconductive belt 8, on which a latent image has been formed by the exposure pattern, rotates and reaches a developing section. 14 is a toner supply section, and p9 is a toner. 13 is a magnetic brush. The toner 9 is rubbed by the rotation of the magnetic bluff 130 and becomes charged. The charged toner rides on the brush and passes near the belt 8. At this time, the unexposed parts of the belt are charged, and the toner 9 with the opposite charge is attracted by electrostatic attraction. do. A pattern is formed on the belt 8 by the toner in this developing section, and as the belt 8 further rotates, it exits from the dark space inside the frame 4 to the outside world. At this time, light from the outside world is irradiated onto the belt 8, but since the toner is already on the belt so as to form a pattern, a pattern based on the color of the toner is displayed in the outside world. If this operation continues and the screen is fully enlarged and displayed at 4C1, the belt will stop rotating 80 times and display only the required time.When you want to display new information next time, the belt will rotate 1m above 8 again to remove the toner. 9 tons of toner in the unit, 29
The toner scraped off by the toner removal unit is collected here, and when a sufficient amount is reached, it is returned to the toner supply unit 14 (and then reused). As the rotation progresses, the charging section 17 charges the lightless mechanism 1.
5, the present invention sequentially acquires information t-

Your eyes won't get tired when using it for a long time, and the fatigue will be the same as when you're reading a book.

On the other hand, δ is a transfer roller, and this roller is at a position K where it contacts the bell) 8 for transfer due to the movement of the support song.
You can move by pressing t. Toner adsorption liquid is applied to the surface of the set roller 50 at the point where it contacts the belt 8, and the toner 9 on the rotating belt 8 is absorbed by the transfer roller 6, and the transfer roller 25 rotates. to transfer the toner onto the transfer paper 2. The toner is fixed onto the transfer paper 2 by applying pressure or heating. ? :, the information displayed here will be printed. 34 is a roller for heating and pressing. If magnetic toner is used as the toner, a method is used in which the transfer section 1 is used as a magnet and the toner is transferred from the belt 8 to the transfer port 511 to the transfer sheet. 28 is a support roller for the transfer paper. Reference numerals 19 and 20 are a driving motor and a roller, and 12 and 2i are rotation speed converting rollers.

Figure jlI4 is a perspective view of the inside of the present invention, showing the roller 27 on which 1# of transfer paper is applied. ) The arrangement of a toner removing section, a driving belt 11 for driving the belt 8, a toner supplying section 14, a magnetic brush 13, etc. is shown. Fifth
Figures α and b are explanatory diagrams of the exposure machine 1!15.

34 is a bar that supports movement of the light emitting section. A light emitting element 31 is provided. 32 is a lens portion for focusing the light emitted by the light emitting element 31 such as a light emitting diode onto the belt 8. 30 is a base for moving the light emitting section. The bar is precisely moved by a 31t linear motor.

Magnets are formed on the bar 34 at a pitch of several tens of micrometers, and an electromagnet is formed in the pace I.

Figure Wc6 is a top view of the present invention.

As described above, the present invention can be used with conventional display bodies such as OR screens and FDPs.
It provides a display method that reduces eye fatigue on the same level as reading a book, which is impossible to imagine.

Therefore, conventionally 0. It is ideal as an educational display that can be used to reduce eyesight if viewed over a long period of time. 1.Its display ability is excellent because it can be done inexpensively.

On the other hand, since it has a printing mechanism, you can freely print out the information you want and save the work records, so it can be used as a home fax receiving device to eliminate unnecessary printing. can be made.

As described above, the present invention provides a socially and culturally significant display printer.
