According to a further embodiment of the invention, each segment is divided into segments conductive layer over an electrical line and over «in photoconductive element with earth potential or any connected to another fixed potential. The potential supplied to each segment is therefore dependent on and proportional to Light falling on the photoconductor connected to the conductive element in the electrical circuit. To this Thus, an image to be reproduced can be scanned line by line along the row of photoconductors, or it can be scanned each opening and the associated photoconductor can be addressed individually, for example via fiber optics. Such Arrangements allow the image intensity to be effective on a j line or in an area of a location, ™ at the same time the projection or printing can take place at another location, even at one of the location remote from exposure or intensity. This feature enables the downsizing or enlargement of areas to be printed compared to the image areas.

The multilayer particle modulator according to the invention regulates and selectively modulates the flow of the toner particles through the Open with the help of electrical Grenzohicht blocking and acceleration fields, which are located within the openings of the Particle modulator to be built. In this regard- (| summarizes the invention in its unitary coordination techniques set forth in U.S. Patent Applications 675 * 99 and 776 by the same applicant. Corresponding to these applications, a multilayer screen provided with openings is created which, at least in certain exemplary embodiments, has a conductive layer and an insulating layer includes, on which a latent electro-static image by Modulating the flow of the charged toner particles or other printing particles created through the openings of the screen

109817/2050

will. The screen preferably comprising at least one insulating layer and one conductive layer enables this Development of a double layer charge on opposite sides of the insulating layer, including selectively within the openings of the shield orenzschicht-blocking and To create acceleration fields (negative through zero to positive). This allows the double-layer charge to be developed selectively around the passage of charged particles to block certain openings essentially completely in order to increase and accelerate the passage of charged particles through other openings and to increase the density of the Tellohen flow through other openings along a continuous basis Bereloh to control in between and thus a modulated flow of toner particles to be reproduced accordingly To create a picture. The modulated flow of toner particles or other charged particles is transferred with the help of an overall applied electro-static projection field transmit an air gap to a pressure-absorbing medium. The image can then be more well known Techniques are fixed.

The present invention differs from the subject matter of these patent applications in that no electrostatic latent image is formed on a screen. The present The invention relates to an electrostatic line printer in which selected fields are individually located within the openings one or more rows of openings can be formed in a multilayer particle modulator as described above became. The invention thus aims at successive or continuous line-by-line printing or printing by scanning rows using selected potentials applied directly to the conductive segments surrounding a series of openings in the particle modulator. An electrostatic latent image is not formed on the modulator. Rather, they are locking and enlarging

109817/2050

20 ^ 9043

Edge fields within the openings between the continuous conductive layer and the segmented conductive layer Not formed on either side of the openings.

When the electrostatic line actuator is in operation, selected potentials are applied to those surrounding the rows of openings Segments are created in a pattern corresponding to the lines to be printed. At the same time, the continuous conductive layer on the opposite side of the particle modulator held at a substantially fixed potential. The resulting double layer charge forms Fringing fields within the openings of the Tellohen modulator. This double-layer charge can not only be used to generate blocking fields at the openings of the modulator but also to create fields of magnification to actively move the particles forward through the openings. With the help of the enlargement fields and the blocking fields, the quality and the control become one contactless Printed with a continuous gray scale. The magnification field enlarges the openings electrically beyond their physical dimensions by pulling the particles out of each opening with the aid of a magnification field in a current which expands in cross section on the output side of the modulator. Enlargement*- Fields are generated by the formation of fields in the openings, the direction and polarity of which are opposite to each other Fields within a blocking opening. White over Orauzu Black print is therefore by changing the electrical potential applied to the conductive segments from negative to positive direction with respect to the feet ·, en die Continuous sliding potential and vice versa are possible according to the charge of the particles. Positive or negative pressure can be achieved by reversing the applied voltages. An electrical Oesamtfeld is charged between the electrodes to move the

1OII17 / 2OSO

nen particles are applied through the openings of the particle modulator and the applied total field is balanced so that it is not sufficient to overcome the electrical marginal fields formed within the openings, which lead to the complete Blocking the flow of charged particles are intended. In this regard, the thickness of the insulating layer and the diameter of the openings selected so that there is a sufficient thickness-to-diameter ratio, in order to generate essentially completely blocking fields within the openings. The conductive layers also serve the purpose of shielding the fields formed within the openings and tend to increase the charge on the to distribute deposited particles to the conductive part of the particle modulator.

A feature and advantage of the present invention is that a continuous and sequential contactless Line printing by forward movement of color particles, such as toner particles or aerosols, directly through the Tellohen modulator onto a pressure-receiving medium that is continuously moved forward relative to the Tellohen modulator, can be reached. This makes it possible to print on unreasonable surfaces.

Another feature of the present invention, however, is that instead of directly passing dye or toner particles through, a stream of charged particles, such as ions, first through the openings corresponding to the pattern to be reproduced for impact on the medium receiving the print can be modulated to «in latent elektro-statlsohss To form an image, which can then be dusted and developed according to known techniques. According to this According to the invention, a number of corona discharge points can be aligned with the openings of the particle modulator, or a corona wire can be aligned with of the Relhs dsr openings are aligned to allow ionic

Generate etrom Ku, which can be moved forward through the openings by an applied general electric field in order to achieve a density modulation according to the pattern to be reproduced. In this embodiment of the invention, the pressure-receiving medium must include a dielectric or insulating layer capable of receiving the latent electrostatic image produced by the modulated ion current. The image is then developed using dry or liquid electrostatic toner processes which are well known. An advantage of the use of ions for forming the image, instead of direct use of dye is that it ä the problem of toner accumulation on the Teilohenmodulator can be omitted. Further objects, features and advantages of the present invention will become apparent from the present description with reference to the accompanying drawings.

The one in the Flg. 1 and 2 shown multilayer partial row modulator 10 consists of a middle, from a dielectric Material, such as plastic, ceramic or glass made insulating Sohioht 11. On one side of the insulating Sohloht 11 is a continuous conductive Solent 12 applied, which consists of a thin layer of metal or a another good leader. On the opposite side of the insulating layer 11 is one divided into segments

109817/2050

conductive layer 14 applied, which consists of a number of insulating, separated conductive segments «which are also denoted by the reference numeral 14. His series of openings or holes 15 is formed by the multilayer modulator 10 and the segments 14 of the conductive sole are designed so that a conductive.-? Segment 14 surrounds each opening 15. To reduce arcing between the conductive segments, the dielectric material of the insulating layer protruding between the segments or a layer of insulating material may protrude over the Entire segmented Sohich'c of the conductive material are formed, wherein the spaces 16 between the segments are covered.

For general use in facsimile reproduction, copying, printing, and computer output, a resolution of 50 to 60 lines per inch may be acceptable "where 50 to 70 openings per inch are required in the particle modulator. When developing a Tellchenraodulator With this resolution the multilayered brain can initially duroh On other soles or deposits are formed and the opening can then be mechanically drilled. At higher resolutions that require as many as 500 or 1000 lines per inch and more, the Opened multi-layer Tellohen modulator, thin film etching and laser burning techniques can be used. An opening diameter in the range of 1 to 15 thousandths of an inch with an insulating layer thickness of about that 1/2 to 2 times the opening diameter has been found to be satisfactory. The strength of the thin film is not critical. With these dimensions, a few 100 volts as a potential between the conductive soles are sufficient to generate the Form marginal fields for blocking and enlarging to modulate a stream of Tellohen through the openings. In general

109817/2050

the greater the potential, the greater the openings. This creates an orifice 1/1000 of an inch in diameter approximately 50% voltage difference between the two require continuous and the segmented conductive layer, while a hole with a diameter 10/1000 of an inch will require approximately a 300 volt differential to form satisfactory fringe fields for blocking and magnification. In each of these examples Assume a total applied field of about, for example, ^ 000 volts per inch to advance the charged particles through the modulator. When using dye components directly, be they dry or liquid, a particle size of approximately 1/8 of the opening diameter is desirable. However, satisfactory results can be achieved with a wide range of component sizes.

Using the electro-static line pressure system of the Tellchenraodulator after the Pig. 1 and 2 become sohaatic in Pig. 3 further shown. In this system, an elongated toner supply 20 provides charged toner cells according to well known methods, and an overall electrical field is applied between the toner supply 20 and the rear electrode 21, the polarity so chosen Place the charged toner cells in alignment on the electrode 21 can be moved forward. In the way of the toner streak is a particle modulator 10, as shown in FIGS. 1 and 2, inserted. A number of lead wires 22, the number of which corresponds to the number of segments in the conductive layer 14, which is subdivided into segments, is indicated in each case Connected to each of the segments 14 of the segmented conductive sole. A single lead wire 23 is old continuous conductive layer 12 connected to a solid Potential, such as a ground potential to be applied to the conductive 8ohioht 12. The number of lines 22 is the first

108! 17 / 20SQ

Addressing source connected, e.g. a logic circuit for outputting a computer result or a graphic computer printing.

The elongated toner supply 20 has a length that corresponds to the length of the partial height modulator and the length of the cells to be printed. Charged particles out of the protective opening 24 in the toner supply 20 are accelerated in the direction of the electrode 21. The linear particle flow is densely modulated as it passes through the row of holes 15 formed in the small plate modulator, and the density-modulated flow then continues its movement in the direction of the electrode 21. In the path of the modulated particle stream g a print receiving medium 25 1st inserted, which by means not shown relative to enmodulator Teilch is moved in the longitudinal direction. Alternatively, the partial row modulator can be moved forward relative to the pressure-receiving medium. Selected electrical potentials are applied to the segments 14 along the rows of openings in the particle modulator with the aid of lead wires 22 at a speed corresponding to the speed of the relative movement of the printing medium 25, so that the diode-modulated linear fields of the toner particles are continuously or successively corresponding to the cells to be printed are sprayed onto the medium receiving the print. The toner particles that hit the printing medium (j 25 and remain thereon) are then fixed, for example by heating, in accordance with well-known techniques.

The addressing of the openings 15 of the particle modulator * with By means of the lead wires 22, direct parallel connection to a "one line per tent" output device can be achieved or sequential addressing can be achieved by connecting each lead wire to a tapped one

109817/205 0

Delay line can be achieved thereby allowing input from a single source which produces a television-like image as the recording substrate or print media 25 is moved relative to the particle modulator. Alternatively, a ring or sleeve (with a conduit attached) may have a portion of each opening inside or outside tie together outside to encompass the segments, allowing a closer spacing between the openings. Furthermore, the openings with an annular cap have provided insulating sleeves that are spaced in the environment are arranged in or on a conductive plate, a grid or a matrix because the coated Ioolator construction with the formation of the double layer charge allows selected sizes and polarities, which on the other hand forms the edge fields.

Instead of directly modulating a stream of dye particles, dry or liquid selenium, the partial modulator can be used to modulate an ion stream for impingement on a dielectric, print-receiving medium or a substrate with an insulating layer that can carry a latent electrostatic image . As in the Pig. 4a and 4b, a series of corona discharge points J> 0 are aligned with the partial wave modulator so that each corona discharge point 20 is aligned with an opening of the particle modulator 10. A total field applied between the corona discharge point 30 and the electrode 31 generates an ion current in the direction of the electrode J> \ _$ which is modulated according to the potentials applied to the segments of the segmented conductive layer of the particle modulator, as described further above. The modulated ion flow continues its movement in the direction of the electrode 31 and strikes a pressure medium or a substrate 32 which is moved relative to the partial current. The print medium or substrate 32 must be a dielectric material or a dielectric

109817/2050

Have layer on which the ions can strike to to form an electrostatic latent image. The line-by-line latent images formed on a printing medium 32 are then developed and fixed by dusting or other means. The electrostatic Zellendruoker system according to Figs. 5a and 5b works in the same way, except that a corona discharge wire 35 die Row of corona points JO replaced. The advantage of using ions as the particles forming the image lies in that it results in simplification of the construction and eliminates the problem of toner accumulation on the particle modulator IKSt. Another aspect of electrostatic pressure with such a modulated ionic current I are disclosed in U.S. Patent Applications 709,578 and 709,660 the same applicant welter explained.

For printing on non-dielectric materials, for printing on irregular surfaces and for multiple overprinting without fixing and drying in between, Direct marking toners such as dry powder toners or aerosols are used.

It can also be a consecutive scan using a single modulated light source along the line of photoconductors. In each of these examples, the image or light source can be relative to the Modulator can be passed through or the Mdoulator can be moved relative to the image or light source. As another example, optical fiber tubing can be used to individually address each photoconductor cell * 40. The «electrical installed in a special segment Potential is thus a puncture of the light falling on the photoconductor connected to the segment and is proportional For this. In addition, other arrangements responsive to optical signals can be used to supply the selected potentials to be used on the segments.

In order to achieve this in the case of the electro-8tätlichen ZeI1endruoksystem according to Fig. 3, can the continuous conductive layer 12 can be kept at Brdpotential, while electrical potential "" changing from negative to positive direction is applied to the lead wires 22, depending on whether blocking or enlarging fields <are required. Furthermore, the continuous conductive layer 12 are kept at a different fixed potential than zero potential and that The electrical potential applied via lead wires 22 to the conductive segments of the segmented conductive base can be applied to one of the sides of the potential

To both blocking as well as enlarging fields for the optically addressable partial modulator according to Flg. 6 to create the lead wire 4-1 is connected to the photoconductor cells 40 * in electrical "potential with a polarity opposite to that of the voltage source applied to line 42 created. As a further example, the "potential" applied to the continuous * conductive layer With this tool, both the direction of the polarity and the strength of the field can be set accordingly of the light falling on the photoconductor elements 40 is changed will. The reversal of the polarity and the field direction of the openings enables switching from positive to negative pressure and vice versa.

By a closer distance between the openings of the Tellohen modulator To achieve a better control of a complete marking coverage, two rows of openings can be used provided in the multilayer particle modulator which are mutually offset, as shown in Flg. 7 is shown. In this figure is a section of a Particle modulator 50 is shown, which consists of a layer of insulating material and a continuous conductive., applied to one side of the insulating material conductive layer as described above. On that of the continuous layer on the insulating one On the opposite side, two rows of conductive segments 51 and 52 are provided, one in segments form a divided conductive layer. The two rows of segments 51 and 52 correspond to the two rows of openings 52 and 54, which are formed by the multilayer particle modulator. Each of these segments 51 and 52 is from every other segment isolating separated. Y / pushln is each of the segments

The multilayer particle modulator created according to the invention can be designed in other embodiments than those specified above. Thus, the conductive layers on either side of the insulating layer can both be divided into segments, with selected potentials as Punctures of the material to be printed are applied to the segments of the segmented Sohicht one side and generally fixed potentials to the segments subdivided layer can be created on the other side. Furthermore, it is not necessary that every segment necessarily surrounds an opening, but rather it may partially surround an opening or be formed in separate parts that oppose opposite edges of an opening issue.

As a further example shown in FIG. 8, instead of the rows of openings, an elongated opening or a Slit can be formed through the multilayer particle modulator 61 for the particles to pass therethrough. At least one The conductive layers on one side of the modulator is divided into segments, with portions of each segment 62 attached opposite corners of the slot in rows abut the slot to form a number of separately controllable electrical fields within the slot.
