Description

[Detailed description of the invention] Back type and outline of the invention The present invention has a high N4 resiliency in the magnetic image storage medium.

The present invention relates to a method and apparatus for generating magnetic images with smooth edges. To put it in a nutshell, the present invention is...

It is concerned with generating in such a medium a generally donut-shaped magnetized region which serves as -N+5 of the total magnetization image. The magnetization within the region is characterized by magnetic vectors oriented in many directions, distributed in a forest-like manner as a whole. .

Recently, there has been a lot of interest in the development of electromagnetic printers. , the basic mode of operation of such a door-sunter is to create discrete magnetized areas within the expanse of the recording medium, and thereby to generate the desired image using an electromagnetic "11-include". The "head" is stiffened and then a magnetizable powder toner is deposited all over that area. The toner 1 is later transferred to paper or the like using various methods.

In the past, individually magnetized regions were combined to form an overall SR in two main ways. One of them is called linear perpendicular magnetization, and the second is called linear perpendicular magnetization.
This method is called linear longitudinal magnetization. The first method is
A pair of N-5 poles arranged along an axis substantially perpendicular to the plane of the storage medium generates a magnetized region. The technique VC produces a magnetic vector oriented perpendicularly (to the plane of the medium) within the magnetized region. #! The second technique is.

Along one side of the media, the film bottle employs a pair of opposing N-3 poles that are placed on the face of the media. With this technique, t1! within 1,000 planes parallel to the plane of the medium! The deflected magnetic vector 1f produces a magnetized region with:

A problem encountered with devices employing such magnetization techniques is that the final magnetized regions exhibit less than good toner collection performance, especially in the areas between adjacent magnetized regions. There is no such thing. As a result, the edges of the printed image are often very blurred. This is particularly noticeable in the printing of alphanumeric characters whose edges are jagged rather than smoothly continuous.

The general object of the invention is to obtain a unique method and device which satisfactorily eliminates such drawbacks in a relatively simple manner.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method by which magnetic images can be generated in which the individual magnetized regions have a very high toner collection performance and the areas adjacent to these regions also exhibit a high toner collection performance. You can get the equipment.

Another object of the invention is to obtain such a method and apparatus which provides very sharp edges of printed images.

That's true.

According to one embodiment of the method of the invention, such magnetic flux generation is achieved by the cooperative action of concentric magnetic poles of mutually different polarity. Those magnetic poles are on the surface of the magnetic storage medium,
It creates a somewhat donut-shaped magnetized region characterized by magnetic vectors directed in many directions that are generally spherically distributed. This type of magnetized region clearly differs significantly in its "magnetic shape" from the magnetized regions generated by conventional techniques and devices. In particular, by creating magnetized regions with a spherical magnetic vector f% characteristic, each region exhibits extremely high toner collection performance. Furthermore, the immediately adjacent N areas face each other,
In other words, we experience all the opposite magnetic vectors. As a result, the area between the contact areas also exhibits high toner collection performance. Such a shape for each magnetized area −
Given that a structure is obtained, and that a series of such areas defines the edges of the image, the toner collection performance exhibited by the depressions between adjacent areas will result in the jagged edges of the final printed image. To illustrate the great versatility of the present invention in preventing the formation of edges.

The construction of some special write heads will be described.

In order to obtain the desired donut-shaped magnetized region with one spherical magnetic vector in each of those structures,
Generally coplanar concentric opposite polarity magnetic poles are used.

Another important feature of the present invention is that magnetic pole pairs having the desired shape can be formed in very small areas in very thin films of variable material. As a result, highly usable, high resolution, low power consumption, and low cost magnetic writing is enabled by the present invention.

Examples of the invention Hereinafter, the present invention will be described in detail with reference to the drawings.

First, refer to the ta1 diagram. In this figure, a write head 22t made in accordance with the present invention--a portion of an image generating device or gauging/metering device--is generally shown with the reference numeral t°. Head 4 is also referred to herein as a magnetic pole structure or magnetic pole element. Also.

Head n is sometimes called a magnetic field generator. This head 4 is used to generate various magnetized areas on the surface of a generally sheet-like transverse medium, such as a magnetic belt. Bell) 24Fi.

It is supported by a suitable feeding mechanism, and the lower part of the head is supported by the upper planar extension. The space between the head and the belt is called the magnetization generation area. Generally speaking, each magnetized area generated by the head η in the plane of the bell) 24 is relatively small, and the final It has come to form only a part of the whole Eirin. Once the image has been formed on the expanse of the belt, a suitable magnetic toner is applied prior to transfer. Nenei gII layered with toner
The final print is made by touching the paper with f') 1. The devices and mechanisms for applying toner are well known.

The explanation about it will be omitted.

To generate high-quality, high-resolution images.

Those \rads are very small. For this purpose,
The structure of the head of the invention shown in FIG. 1 is too large. However, in order to demonstrate the usefulness of the present invention, during the development and early implementation of the present invention, a head of the structure shown in FIG. 1 was actually constructed and tested with satisfactory results.

Head n is a pair of magnetic pole members! , 30'i included. The member 28 has a yoke shape 9, a generally inverted cylindrical tip f32 on the upper side, and a disc mark closing the bottom of this tip. (2 and 7 disks are made of a suitable magnetic material such as silicon, and 7 disks are made of a central round hole 34a.
The second magnetic pole contains 9 members and 4 things! ! I will call it elemental.

The pole member (9) has a generally cylindrical stem shape. This member (9) is the second magnetic pole element part 7 32
#t is attached to the center of the interior of the tip 1, and the upper end thereof is magnetically coupled to the inner surface of the top of the tip 1 part 32. The lower side of the component (material) is a circular hole in the center of a disc-like shape, and it is polished in the F direction through the inside of W a.

3 members whose bottom surface is almost the same as the bottom surface of the disk: i)
Also made of silicon steel. Member I will be referred to as the first magnetic pole element. Cop: A coil is wound around the upper part of the magnetic pole member I in U2. The ends of this coil are led out of the tip and connected to a suitable DC cable. The coil is sometimes called the excitation element.

The space other than the member force in tip f32 is occupied by a cylindrical brass filling member as a whole. This member 38 functions as a diamagnetic material. A gold-plated copper collar is placed in the gap between the holes 34a.The collar also functions as a diamagnetic material.The lower end of the collar is flush with the bottom surface of the disk.

The dimensions of a structure that has been found to be satisfactory for a small head actually used will be described in the explanation given in full reference to Part 5-1.

What I have explained so far about the configuration of Head O is:
This section describes important structures of the present invention. In particular, what is implemented is a central magnetic pole surrounded as symmetrically as possible by the surrounding magnetic poles defined by the lower rim of the disk.
It has a concentric magnetic pole structure that contains the lower surface of the member force.

The belt 24 includes a flexible support layer 24a and a flexible support layer 24a.
This is a normal structure consisting of a magnetic layer 24b supported on top of the magnetic layer 24b.

Next, referring also to FIGS. 2 to 4, when the belt 24 is in the position shown in the first row with respect to the head ρ.

When the head ρ is excited, the magnetized layer 4 in the magnetic layer 24b
2 is generated. This magnetized layer 42 has a generally circular center portion 42a and an annular portion 4 that almost symmetrically surrounds the center portion 42a.
2b,l! It has a shape that is a combination of :. In FIG. 2-3, portion 42a is labeled with the letter N to indicate north pole magnetization, and portion 42b is labeled with the letter S to indicate south pole magnetization.

Due to the shape of the head in the area of the collar 40 and the presence of magnetic flux in the gap between the upper end of the member and the inside of the round hole 34a, the shape as shown in Figure 5 is obtained. A magnetized area was obtained. As a result, and because the magnetic circuit is completed by the VJ magnetism of the heads, the magnetic flux has a somewhat tortoise-shaped distribution, with the portion S mostly occupied by the belt 24b.
Empty within #it - extends across.

As a result, the shape of the magnetization of the magnetized region 42 as a whole also becomes donut-shaped, and the magnetic vectors are distributed spherically. In FIG. 2, lines representing magnetic flux extend upwardly from central portion 42a and then curve outward to peripheral portion 42b. In FIG. 3, the arrows indicate the radial nature of the magnetic field lines between the two portions 42a and 42b of the region 42 where they are magnetized.

FIG. 4 shows the structure of the magnetized region 42 in detail. In particular, the magnetic flux connecting the central portion 42a and the surrounding portion 42b'i is expressed by the broken line 4.
forming what can be thought of as a donut-shaped area, generally represented by 4. With such a distribution of magnetic flux, a straight line drawn tangent to all the magnetic fluxes at every possible point represents the magnetic vector in this magnetized region. It is clear that these vectors describe an almost perfect sphere in space. This is represented by a 7-dot chain line 46.

The above-described situation exists in the layer 24b when there is no K&B bias for each belt layer. However, it is common for magnetizable regions in media, such as belt 24, to be subjected to a preselected magnetic bias1; for purposes of this discussion, +
1*24b is biased in the direction shown by arrow 48 in FIGS. 2 and 3, the head of the arrow indicating the direction of the north pole at this bias. As a result of the bias in layer 24b, the bias vector interacts in layer 24b with the magnetic vector created by the action of head B, producing a magnetic field with a shape slightly distorted from the ideal shape just described. . Any two such lines that are not perfectly straight from each other
Magnetic interactions occur between the two vectors at all interaction locations. Air gap magnetic flux is generated. This magnetic flux, together with the magnetic flux generated by the excitation of the head °n, helps to collect the toner.

Experiments have shown that a magnetized area shaped like area 42 exhibits excellent toner trapping properties, thus resulting in very sharp toner edges. A magnetized region like
In actual printing, it is extremely small and forms only a portion of the entire image. The image may be a letter/number character, a line in a graph or shape, or part of a field that defines an extended image. Therefore, it is intended to use a large number of relatively closely spaced magnetized regions distributed in various preselected turns to form the entire image. As will be explained later, the shape of each magnetized region causes a unique and significant magnetic interaction between adjacent regions.3 Here, belt 24 is moved slightly to the left in FIG. Suppose that head n is moved and re-energized to produce another magnetized area. The areas are indicated between the reference numbers in Figures 2 and 3. Similarly to region 42, region I includes a central portion 50a, which is symmetrically surrounded by a circumferential portion b.

The magnetic structure between the regions is approximately the same as the magnetic configuration of region 42.

The adjacent regions between regions 42 and 50 have components whose magnetic vectors face each other. As a result of this important opposite vector situation, the regions between adjacent magnetized regions also have higher toner collection performance. will be shown. Therefore, in the final printed image there will be good continuity within the areas between adjacent image parts. This is in sharp contrast to conventional magnetic image generation techniques, where no such pickup exists in the area between the magnetized regions. Another important insult of this phenomenon is the third
It is indicated by broken @52 in the figure. Here, the area 42,5
It is assumed that the portion of the total image contributed by 11) has a portion of one edge that is subtended by the lower edge of regions 42, 50 of FIG. Because toner collection performance is poorer in the area between regions 42 and 50, that area is filled with toner during the door lint operation, resulting in a relatively smooth flow as shown by dashed line 52. This results in edges without burrs. It is because of this improved inter-instrument toner collection performance that the inter-interval toner collection produced according to the method and apparatus of the present invention exhibits very sharp edges.

In order to simplify the foregoing description of the three basic features of the method and apparatus of the present invention, the description will briefly ignore considerations of dimensions, practicalities of ultimate operation, and will be fairly basic. It was about a simple and easy-to-understand adjustment of the head. In history.

The magnetic structure of magnetized regions produced in accordance with the present invention and the advantages of such a structure have been described with reference to FIGS. 2, 3 and 4. What is described below has been found to be extremely satisfactory in generating a practical high-strength image. 2nd 5th, which is somewhat more advanced structure of some advanced write heads.

It is.

Referring first to FIG. 5, a write head structure M includes a plurality of write heads made in accordance with the present invention.

Each head J6 includes a structure that can be thought of as a mother-cake sandwich structure, and when viewed from the top perspective of FIG. 5, the structure is circular.

The center axes of adjacent heads of head elf & body 8, for example the axis of head I, are approximately (J, 13clL(
One of the adjacent heads, separated by 5 Cl mils), is indicated by a number (A).

The head structure 54 is in the form of an endless flexible pole that can be hung on a support tram) Furthermore, as will be clear from the following description, the head structure 54 has very large cross-sectional dimensions. This structure, which is small and thin and made using thin film and IC technology, offers several advantages. Head 56 represents the structure of each head in head structure M. What is considered to be a four-way support between the head structures is a magnetic material made of a magnetic material of equal permeability and conductivity.

It is.

In this specification, Kuep 62 is also referred to as a reef scattering element. This web 62 constitutes a second pole element in the area of each built-in head. In the main head structure, the thickness of the web 62 is approximately 0.0038 tyst (approximately 1.5 mils).

A chi-shaped opening 1 is provided in the web 62 about the axis 58, and this opening is located in the web 62.
l) Open on both sides. The upper, larger diameter end of this opening has a dimension B of about 225 microns and the lower smaller diameter end, C, has a dimension of about 125 microns.

Gold collars are distributed around the wall inside the opening. The collar 6, which acts as a diamagnetic material between the pole faces of the head group of the head structure, extends slightly above the upper surface of the web 62 in FIG. The thickness of the color group is approximately 18 microns. As a result, the color φ
The inner diameter 0 at the lower end of is approximately 90 microns.

As mentioned above, the material of web 62 is both magnetically permeable and electrically conductive. Thus, in addition to functioning as a diamagnetic material defining a low permeability gap between the pole faces of the head shaft, the collar also functions to make electrical contact with the web 62. The reason for such contact will be explained later.The upper end of the collar closure in FIG.
to come into physical contact.

Further, the spiral winding part B is formed integrally with the coil coil a, so that the coil can be easily considered. The winding 68a is arranged substantially symmetrically about the axis 58. As can be seen from FIG. 5, the first winding 68b is substantially flat and disposed within a plane slightly above the upper surface of the fifth and fourth webs b2. The area of the cross section of the winding 68b is approximately 6゜4XI0 - square r11
L (approximately 1 square mil). The coil strip is also referred to as an excitation element. FIG. 6 is a view of the top of the coil strip along the axis ')8. The coil mallet is shown taken out from the head group.

In FIG. 6, winding 68b is wound four times around axis 1s58 and then extends tangentially around the coil from axis 1Mj58 to terminal ground 68c. The terminal/fourth lead I is included in almost the same plane as the plane in which the winding 68b is included,
A hole 68d is provided in the center thereof.

The purpose of this hole 68d will be explained later.

Referring to Fig. 6, the throat of the 2nd winding section is f58cF.
i It is embedded and supported in a suitable dielectric layer 70.

The thickness ε of this Nl70 is about a micron. A suitable material for forming layer 70 is UiltE. 1゜Dupontd

Head structure 54 is covered with a layer or blanket 72 of non-conductive, high permeability magnetic material. This material is made of 1#+nickel and zinc. As can be seen in the figure, the blanket 72 extends downwardly at the center of the head.
8 Enter the inside of a and the color gloss. The portion of the blanket 72 that is inside the collar is called the first magnetic pole element, and in FIG. 5 has a bottom surface. This bottom surface is at the same level as the bottom surface of web 62. 22 socket 72 defines the top of spatula P56. roll! The upper plank door 2 part of l68b is circular as a whole, and its diameter is approximately u.
, 102 CIL (approximately 40 mils)) blanket 72 is also distributed over all other write heads of head structure 9 and serves the same function as for the two heads. The contact between blanket 72 and web 62 constitutes a magnetic connection. Appropriate gaps are provided in the blanket to allow electrical connections to be made to the center hole of each coil end or throat.

A number of techniques are used to make write heads.

The following description is particularly satisfactory.

First, the web 62 is created by applying a thin (several micron) gold plating to the pace. 4- Plating 1111 is 2 in Figure 5.
This is indicated by a dotted line 74. This plating t- will be removed later, but the bottom surface of the constructed head structure 'fr'
The purpose is to facilitate a smooth new look.

Next, the upper surface of the web is coated with pyraHn. This secundum extends above the surface of the kuep to approximately the same level as indicated by dash-dot line 76 in FIG.

Next, the continuous Pyral In coating is selectively etched to locate a number of hems that can be attached to the head structure. Did you do etching? The island of Pyraln obtained by etching lkt'1=-t has a generally circular main pedestal. This main mezzo is provided with a central circular hole, and a generally radial projection is connected to the pedestal. For each island, the circular main hollow portion is for receiving a coil, such as a coil strip, and the center hole is for receiving a tip 68a within the coil.

Further, the protrusion is for receiving a terminal such as a terminal.

It should be fully understood that the islands of Pyralln differ somewhat from each other in order to increase the density of heads contained within the head groove structure. Historically speaking, many islands are quite long and narrow, and can be twisted together. It also constitutes a protrusion that is screwed into the space between the heads. These are intended to provide convenient locations for making electrical connections to terminals and flats. Therefore, the particular island shaped to provide coil support is typical in a general sense of the quality provided for other coils in the head 9 structure. .

Once the PyraIn island is created, the top surface of the head structure is plated with steel and then photo-etched to form the coil. Following this etching, what is left of the original copper plating is used to form specific coils for the various heads.

winding, opening, opening). After the copper coil was formed, Pyrall was applied to the entire surface of Hera)'#44 body.
The second layer on which the I- is redeposited is selectively etched so that the second layer is only deposited on the previously formed islands.
(Leave the Pyral in layer) Also, add a second Pyral layer so that it can be connected to the coil inside the coil.
Make a hole in I-.

Second, the entire head reservoir, such as head reservoir hole 64, is drilled using conventional techniques. Once a hole is made, the inner surface of the hole is plated with gold to make it look like the color before coloring. This is done so that the top end of the collar is electrically connected to the tip inside the coil. The collar is also electrically connected to web 62.

After the collar is made, a blanket of zinc 72 is applied over the entire head structure to surround each write head. This blanket is selectively etched to provide connections in the coil to the heel/arm throat. Finally, the bottom surface of the web is treated to remove the gold plating layer 74, thereby leaving the bottom surface of the bottom structure M with a continuous smooth finish.

This head structure can be made without the gold plating layer 74, but during electrolytic drilling, for example, to make holes in the write head, it is deformed where it emerges from the underside of the hole f62. Experience has shown that (flare) can occur. In that case, if the gold-plated layer 74 is present, even if deformation occurs, it is a sea urchin! It occurs in the gold layer rather than in the gold layer. Therefore, removing the gold layer 74 leaves a flat bottom surface. For maximum magnetic writing performance, it is important that the pole faces at the bottom of each hole be approximately on the same level as each other.

The multiple write head structure thus produced is loaded with equipment for use in any reasonable manner. Because of the electrical conductivity of the web 62, the shoulders of each coil are independently connected to the other side of the power supply via appropriate switching circuitry.

Reference is now made to Figure 7.8. 78 depicts another embodiment of a write head structure similar in some respects to the father write head structure. Head structure 78 includes a plurality of magnetic write heads. The axis of the head is indicated by a dash-dotted line and is separated from the axis of the adjacent head in the same manner as described for the head structure 8.

Head structure 78 includes a web 86 that functions similarly to web 62 described above. Each head is provided with a hole.

For example, a head zeki is set up as an ozeki. web86
The material of construction is the same as that of web 62, which material forms the pole member at each head location. First, the thickness of nib 86 is approximately equal to the thickness of web 62.

The configuration of the individual write heads included in head structure M is generally circular and nine-cake shaped. In contrast, the write head of head structure 78 is generally rectangular. For example, the long axis of the head 8o (FIG. 7) is substantially included in the paper plane of FIG. , dk, the reason why the configurations of the heads are so different is that the shapes of the respective excitation coils are different.

A golden collar (i) is formed among ozeki. This collar (i) functions in the same way as the collar (shi) of Irinododan. As the collar (A) rises above the top surface of the web 86 in FIG. be done. Generally, the layers follow the direction of the longitudinal axis of the head.

Blanket 72 on the @2 magnetic pole member of
A blanket % of the same magnetic material used to form the magnetic material is formed. Blanket 94 is applied over the entire surface of head structure 78 to form the magnetic pole member of each head. In the area of each write head, such as the head area, the blanket is generally T-shaped (FIG. 7) when viewed in cross-section along a plane containing the rad long sleeve. The blanket thus includes a central stem 4ai extending downwardly into the collar (a). This stem 94 a tt
, a pair of bald coaxial arms that sharpen outwardly, proximate to its upper end.

For example, arms 94b and 94C are connected. At the outer ends of their arms the blankets are connected to webs 86
and contacts the web 86 . The blanket thus magnetically contacts the web.

Excitation coil% is provided in the head (capital) 1, coil%
contains separated coaxial windings %·1%b. The windings extend around arms 94b, 94c, respectively. Winding prostitute a! 6b is indicated by a dash-dotted line.

Next, referring also to FIG. 8, windings %a and 96b are wound in opposite directions about axis 98. If you look at the coil % from the left side of the coil along the axis-to-wall in Figure 8, and if you trace the coil from the left end to the right southern part, the movement will be reversed while moving along the winding width a. Clockwise and winding?
It is clockwise while moving along fML116b. Coil % winding 4196a.

The reason for winding 96b in opposite directions will be explained below.

Generally, arms Xj6a, 96b are Pyral
surrounded by a cylindrical fracture plate of lng. This covered maki is finished.
It extends into the space between the arms 94b, 94c and the upper side of the gold mist, around one side of the arm, and through the center of the top of the arm. If the pyramid extends over the end and stem 94a, a copper spacing layer 102 is provided.

The -gs of the coil 96 is in electrical contact with the web 86, and the other end extends toward the aforementioned terminal, such as the arm and throat. The terminal 9 is Pyralln layer 100
supported on the serving part of the

Although the internal structure of the write head of head structure 78 seems to be a little more complicated than that of the write head of head structure M, the fabrication of a head similar to the head structure 78 is similar to that described above for the fabrication of the head. Those skilled in the art can easily make bamboo using this method.

The reason why reverse spiral windings are used for coils like the coil % is that when a current flows through that coil in a given direction, the nine magnetic fluxes generated by each winding are in opposite directions, and the stem 'j4a' This is because it produces a strong magnetic pole.

9 and 10 illustrate yet another embodiment of the write head structure of the present invention. This figure shows a web 104 that is similar in structure and material to the two-plant webs described above.

Multiple write heads are formed within the web 104. The central axis of the head 106 is indicated by the number 108;
The distance between the center axes of adjacent heads is similar to the distance between the center axes of the heads in the head structure. A channel 110 is formed in the upper surface of the web 104, and the cross section of this annular channel 110 is generally rectangular (first
θ diagram).

The circular region of web 104 surrounded by channel 110 forms one of the pole members within head 106 . The portion of the web surrounding the outer periphery of the channel forms the other pole member of the head.

Inside the channel 110 is formed a lining 112 of a suitable electrical conductor, such as silicon oxide.

A steel ring 114 with a gap 114a is formed in this lining 112. Between I! Inside the t1114a, there is a silicon oxide conductive eyelash No.-116 (9th

Although the structure shown in FIGS. 9 and 10 has been described as including a pair of conductive leads extending to ring 114,
One end of the web 114 (next to the gap 114a) is connected to the web 104.
It should be understood that it is directly connected to the lips.

The web 104 serves as a common electrical conductor for energizing the rings for all write-to-side rings.

Several embodiments of the method and apparatus of the present invention have been described above. In each of these embodiments, energizing the write head produces magnetic pole faces of opposite polarity that are generally spherically distributed in the magnetic image storage medium. From what has been described above, it is understood that there are several ways to implement the invention, and that some of the structures described may be completely modified. You will find that there are several. Imaya 2 Invention Il)
