Abstract

PURPOSE:To attain the display with high density without causing wrong influence to eyes even with observation for a long time, by attaining the display and print with the electrostatic transfer. CONSTITUTION:A dielectric belt 8 is turned toward the arrow with a roll 22 and charged electrostatically with a corona discharge at an electrostatic charging section 17. The display information transmitted externally is erased for the charge corresponding to a pattern with a linear discharge by means of the latent image forming pattern at an information processing section 16 and the latent image is formed on the dielectric belt. The dielectric belt 8 is turned further and reaches to a development section. In figure, 14 is a toner supply section, a toner 9 is charged previously and passes through the vicinity of the belt 8 on a brush 13. Since the part not erased with discharge on the belt is charged oppositely, the toner is adsorbed on the belt with the Coulomb's force.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a display in which a dielectric material is formed into a belt shape, the toner developed for display is used as it is, and a latent image is formed using a multi-stylus in a display printer used for notebooks. Regarding printers.

Conventionally, various types of displays and printers have been announced and commercially available. However, until now, there has been no compact display with a notebook function that integrates a display and a printer. In addition, there has not been a concise display that is inexpensive, has a high display density, and is flicker-free.

The present invention overcomes the above-mentioned drawbacks and makes a display printer more compact, which does not hurt the eyes even when viewed for a long period of time, can display a high-density display, and has the function of freely printing the displayed content. be.

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 the display section, 2
is the printing paper, 6 is the dust from the operating vehicle, and 4 is the frame.

FIG. 2 is a sectional view of the dielectric belt. 5 is a dielectric material such as Mylar, and 6 is a layer of conductive material such as Afi.

First, the surface of the dielectric is positively charged by corona discharge at the charging section. Next, this charged belt advances to the latent image forming section. In this latent image forming section, a multi-stylus is set at a distance of about 10 to 20 μm from the dielectric belt. Corresponding to the required pattern to the many electrodes of this multi-stylus, a Norse voltage of opposite polarity to the already charged one is applied to generate a discharge. This p
The electrostatic charge is removed in accordance with the pattern to form a latent image.

FIG. 3 is a longitudinal cross-sectional view of the invention. The dielectric belt 8 is rotated by the roller 22 in the direction of the arrow in the figure. The dielectric belt 8 is p-charged by the charging section 17 by corona discharge. The display information sent from other devices is converted into a latent image forming pattern by the information processing section 16, and the charge is erased by linear discharge with 15 multi-styli (/ An image is formed. Reference numeral 18 is a pressure booster for corona discharge.

The dielectric belt 8 further rotates and reaches the developing section.

14 is a toner supply section, and 9 is a toner. 13 is a magnetic brush. In this embodiment, a toner using a magnetic material as a carrier is used. The toner is charged in advance and passes through the belt 8 at a proximate point on the brush. At this time, since the parts of the belt that have not been erased by discharge are charged in the opposite direction, the toner is attracted onto the belt by Coulomb force. By this development, a pattern is formed on the belt 8 by the toner.

By further rotating the belt 8, the frame 4
Exit from the dark place inside to the outside world. At this time, external light is irradiated onto the toner on the belt 8, and a visible color pattern is displayed. If this operation is continued and the image is displayed to the full screen size, the belt will stop rotating 80 times and the image will be displayed for the required time. The display time can be several (5) or even several hours, and since no electric power is required to continue the display, it is a very energy-saving display method. Next time you want to display new information,
The belt 8 is rotated again and the toner 9 is scraped off by the toner removing section 23. Reference numeral 29 denotes a toner collection section, in which the toner scraped off by the toner removal section 23 is collected, and when a sufficient amount is reached, it is returned to the toner supply section 14 for reuse. The belt 8 further rotates and reaches the charging section 17.
The latent image forming section 15 directly discharges electricity using a multi-stylus in accordance with new information to form a latent image.

By repeating the above steps, the present invention can sequentially display information. Furthermore, when toner is used for display purposes for a required period of time as in ORT, σ) eye fatigue f1 does not occur, and the fatigue is exactly the same as when reading a book.

On the other hand, 25 is a transfer roller, and by movement of the support 26, this roller can be moved to a position where it can contact the belt 8 for transfer. A toner adsorption liquid is applied to the surface of the roller 250 set at a position in contact with the belt 8 for transfer, and the toner 9 on the belt 8 that has advanced is adsorbed to the transfer roller 25, and the transfer roller 25 is rotated. 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 is
It will be printed. 35 is a roller for heating and pressing. 28 is a support roller for the transfer paper. 19

FIG. 4 is a perspective view of the interior of one embodiment of the present invention. A roller 27 wrapped with transfer paper, a toner removing section, a driving belt 11 for driving the belt 8, and a toner supply section 1

5 and 6 are a partial side view and a front view of a multi-stylus for latent image formation. Reference numeral 41 denotes discharge wires, which are formed in large numbers at intervals of several tens of μm in width. Further, the diameter of the wire is about 50 μmIrL. 42 is an insulating mold part. To create a multi-stylus, wire is wound around a large-diameter rotating body at a uniform 6-pitch, molded with insulating resin, and cut to the required width.

By using this multi-stylus, the thickness of the device of the present invention can be significantly reduced by 7 mm compared to other methods, greatly contributing to compactness.

As described above, the present invention provides a very compact display system that can significantly reduce eye fatigue, which could not be realized with conventional displays such as CRTs and FDPs. Therefore, it does not take up much space even when placed on a desk as a display for personal education. We provide products with high density and large display area at low prices. Due to its compactness and flexible printing capabilities, it is ideal as a home fax receiving device.

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