Unlike the mahjong pieces with the thickness of 3mm-5.5mm or 5.5mm-7.5mm, the mahjong pieces with the structure are symmetrically provided with at least one row of three-dimensional bulges with the bottom surfaces of various geometric plane figures and the top small and the bottom large on the upper and the lower end surfaces arranged along the width direction of the mahjong pieces or at least one row of the strip bulges with the top small and the bottom large on the upper and the lower end surfaces perpendicular to the length direction of the mahjong pieces, wherein the strip bulges extend along the width direction of the mahjong pieces and the cross section perpendicular to the extending direction of the mahjong pieces are symmetrically arranged on the upper and the lower end surfaces perpendicular to the length direction of the mahjong pieces.

The invention has the advantages that the chess and the card have the directional magnetic conduction function in a certain direction through the magnetic wire harness channels with lower magnetic resistance formed by the special distribution and arrangement structures of the magnetic particles with different shapes, sizes, numbers and directions arranged on the chess and the card, and are matched with the stand and the chess tools, so that the chess and the card with the thickness less than or equal to 7.5mm and the portable chess and card tools corresponding to the chess and card tools can be manufactured, the standing of the card is not dependent on the size of the bottom end area of the card, the volume of the mahjong and card body can be theoretically and infinitely reduced, and the trouble that the card cannot be held or standing is avoided due to the fact that the card is too thin is avoided; further, since the game is used, the following advantages are brought: the scratching and holding of the ultrathin chess and card on the table top is converted into the upward sucking and lifting actions of the permanent magnets of the chess and card, so that the physiological defect that a human hand is not easy to scratch and hold a thin object on a plane is overcome; thereby saving time and labor and also increasing fun and chess playing efficiency. Chess and cards provided with a magnetic wire harness channel with lower magnetic resistance in a certain direction are not mutually and passively adhered when playing chess or mahjong; and can be randomly picked by means of one or a stack of chess; in addition, by means of the stand-up supporting frame, mahjong pieces can be tidily and stably leaned side by side, the tabletop can be taken away and held in hands, and the four stand-up supporting frames can be matched with the rectangular packaging box frame to assemble the mahjong piece packaging box, so that the mahjong pieces are contained, the mahjong piece stand-up supporting frame is portable to carry, and can be carried in a pocket.

The chess and card is made of magnetic material particles and matched with the chess and card game and the stand, so that the defects of the prior art, such as the chess pieces which are flatly placed together on the chessboard and touch each other or the mahjong pieces which are formed into piers and are discharged, are overcome, and the middle part of the chess and card game is not isolated by a large magnetic resistance material, so that the defect that the chess pieces should be taken and the chess pieces should not be taken and are mutually sucked and connected passively when the chess is played is overcome. Obviously, if no spacer ring is added and the pure iron chess board in the prior art is adopted, only one strong permanent magnet is used anyway, then if the go pieces contacted side by side or the mahjong tiles arranged in piers are started, (the prior art does not meet the mahjong tiles at present) especially the latter, the go pieces and the mahjong tiles can be sucked into a group passively, and for quick sorting among each office, the sorting of the piled pure iron chess boards is not easy to realize due to the defects of the prior art; for the invention, whether a chess or mahjong playing card is operated singly or a stack of go playing cards is lifted, and whether the go playing cards, the chess and the like are moved by walking or the office is quickly sorted, the chess playing card and the chess playing card can help the stand body to finish the land and be handy; in a word, it makes both chess playing and mahjong playing become comfortable and happy and recreation; in addition, the invention truly reduces the volume and weight of the chess and cards by more than ten times, thus the corresponding chess and mahjong cards are possible to be miniaturized and carried out for a long time, and the invention mainly solves the problem of long-term confusing portability by virtue of the thin advantage of the chess and cards, which is the disadvantage of being unable to be taken up and standing, but the disadvantages are fully compensated by the combination of the chess and cards, the chess and cards and the stand-up support used by the invention, and the prior art has the defects from the chess and cards to the chess and cards. Thus, a pair of larger and heavier weiqi or mah-jong pieces can be reduced to the up-down size of one to two playing cards, even smaller; several kinds of chess, such as Chinese chess, chess and land battle chess, are combined together to form 154 pieces of chess, (32 pieces of chess and chess are used as two kinds of chess, one set of chess can be assembled into one box, and can be used as front and back sides, and can be used as less), so that it is suitable for various lovers, and is favourable for propagation and communication between various places of every country, and can save lots of raw materials and cost, and is favourable for batch production, and the product can be conveniently put into clothes pocket like mobile phone, and can be conveniently carried about, in particular for 144 pieces of mahjong, for example, four pieces or six pieces are piled up as one pier, and can be swung down by only 36 pieces or 24 pieces on the table top, and one square stool can be swung down by only about 20 square centimeters or 14 square centimeters on the table top, and obviously is very suitable for places such as train, ship, temporary hotel, etc., so that it can be truly carried about. In addition, the mahjong pieces are miniaturized, and the mahjong pieces are benefited by the stand-up support, when not in use, the mahjong pieces can be assembled into the mahjong packing box at the same time, the space is not occupied, only one packing box frame is needed in the middle, one object is used for two purposes, the stand-up support is used, the necessary condition that the mahjong pieces can stand only by relying on the large enough area of the bottom end of the stand-up support, so that the volume of the mahjong pieces can be infinitely small in theory, and the volume of the mahjong pieces is small; the stand-up support has the function of adjusting the elevation angle of the mahjong tiles when standing, is more relevant and humanized, and can be integrally supported by hands for playing when being convenient; because the finger sleeve of the chess can be used, the chess not only can overcome many defects in the prior art, but also can complete various special functions, and simultaneously, the chess can also have the function of finger scratching during playing mahjong.

Detailed Description

Description of various chessmen, mahjong pieces and power-assisted frame bodies in the invention

All the chess pieces related in the invention comprise chess pieces or mahjong pieces with the thickness of 0.1-0.5mm, 0.5-5.5mm or 5.5-7.5 mm; the chess adopts the method that common plane general chess icons are printed on the positive end surfaces of the flaky chessmen, namely the chessmen of the chess are plane pattern chessmen. The checkers are similar, are flat and round piece pieces printed or coated with corresponding colors and icons of the simple six checkers, and are also printed patterns Fu Qizi of the plane patterns. In addition, the weiqi in the invention is a flat disc-shaped piece which is not represented by characters and is only distinguished by black and white colors; the other chess types such as Chinese chess, korean chess and land battle chess are all expressed according to common corresponding characters, colors and icons. The thickness direction of the chess board is defined as the thickness direction of the patterns or characters, and the direction perpendicular to the surfaces of the patterns, the characters or the icons is taken as the thickness direction; no pattern or character, the playing state is used as reference, and the direction perpendicular to the chessboard is used as thickness direction, such as checkers and go. The plane is the front face of the chess board with patterns, characters or figures. The number and the sizes of the chess and the card are prepared according to the actual number or the sizes of the commonly used chess or card types, the chessboard is correspondingly configured according to the corresponding chess types, and the number, the shape and the like of the used chess pieces are not related any more in the embodiment, except special requirements.

The auxiliary stand frame body has a long surface, a wide surface and a high surface, wherein two opposite surfaces are hollow and transparent, and the surface where the length and the height are shared is the long and high surface; the surface where the length and the width are shared is a long-wide surface, and the long-wide surface is hollow and transparent; the surface where the height and the width are located is the height-width surface.

In addition, the seven distribution and local construction principles of the magnetic material particles on the chess and card can be seen in the corresponding technical scheme. Distribution characteristics and theoretical basis of magnetic material particles and/or powder on chess and card:

in order to explain the principles according to the present invention in more detail and to analyze the three-dimensional distribution of the magnetically permeable particles and/or powders on the playing pieces according to the principles, we first describe and define several relevant physical quantities and conditions:

description and definition:

1) The magnetic material particles and the magnetic material powder and the linear density concept are added with the specification or definition of the thickness and thickness direction of the chess and card, the three-dimensional rectangular coordinate system X, Y, Z, the direction and the like:

the magnetic material particles mentioned in the present invention refer to a magnetic material body having a certain linear dimension macroscopically and having a certain geometry and number; the magnetic material powder body refers to a macroscopic aggregate of magnetic material particles which cannot be separated in size, shape and quantity.

(II) in a space where an object is located, along a certain direction, a number W of particles distributed along a certain line length in the certain direction of the space, and a ratio of the number W to the line length is called a line density value n of the particles in the line length in the certain direction, wherein at most only one particle can be distributed in a unit length, namely the maximum three-dimensional equivalent length of a single particle is equal to the unit length, and the line length is set to be an integral multiple of the unit length for convenience of explanation; in addition, the particles referred to in this description are magnetic material particles or powder thereof, for convenience of explanation, the magnetic particles larger than one unit length volume in the three-dimensional space of the chess and card are regarded as an aggregate of a plurality of magnetic material particles or powder with unit length volume size which can be separated and gathered together, and the magnetic material particles or powder referred to in the discussion exists on the chess and card body.

And (III) defining the z-axis direction in the rectangular coordinate system as consistent with the thickness direction of all the chess pieces, namely: the top view image or the icon of the putting state from top to bottom when all chess pieces are played is regarded as the positive end face image of the chess board, and the images of the top view image or the icon are all common icons or patterns corresponding to the chess, except when the land combat chess is played in a standing mode. The most typical chess icon comprises a front face situation formed by turning over chess pieces of a land battle chess when two persons turn over the chess pieces for entertainment, wherein a mahjong picture is a front face image when the mahjong pieces are upwards when the mahjong pieces are laid down and lie down, at the moment, the vertical direction of the front or back end faces of the chess pieces is defined as the thickness direction of the chess pieces, and the front end faces or the back end faces are parallel to each other, namely the Z-axis direction; x, Y are mutually perpendicular and perpendicular to Z.

(IV) cyclic or cyclic-like definition: not only is the following: the ring shape is a complete closed body which is formed by enclosing a ring plane central area by the same material and is provided with a hollow body, and the peripheral edge and the cross-section plane of the ring of the closed body enclosed by the ring shape are relatively gentle in change; wherein, when the hollow body contains a material which is different from the material of the annular body, the hollow body is still an annular body according to the three-dimensional space body which is surrounded by the same material containing the material. The ring-like body is ring-like, but is not closed or is closed but has a large abnormal change in a part of the ring-like shape of the main body, and is called ring-like, for example, the change of a non-magnetic material around a sharp corner part of a circumferential plane formed by the chess blank is a large abnormal change.

(V) monomer strong permanent magnet: the invention only has a pair of magnetic poles which are naturally formed during manufacturing, and the magnetic attraction force can attract at least two single permanent magnets of the chess board.

2) Lower reluctance magnet wire harness channel description:

generally, if a magnetic path formed by at least one particle and/or powder of magnetic material having a linear density value of greater than 0 and less than or equal to 1 is provided from one end to the other end along the path through which the magnetic field magnetic wire harness passes, the magnetic path is referred to as a magnetic wire harness path having a lower magnetic resistance to distinguish between a magnetic wire harness path such as air or other non-conductive or weakly conductive material, such as a magnetic wire harness path formed in air, liquid or other non-magnetic solid material without magnetic material, and a magnetic wire harness path having a lower magnetic resistance, on a general magnetic path without the distribution of the particles and/or powder of magnetic material.

3) Permanent magnetic tape: the permanent magnetic tape is a general name of permanent magnetic rubber body or plastic permanent magnet with a certain three-dimensional volume or a permanent magnet aggregate with at least more than two permanent magnets laid in a certain line length along a certain direction. Such as a magnetic rubber body on a stand or a plastic permanent magnet in the invention.

And (II) analysis: with magnets in the chess or cardFor convenience of discussion, as shown in fig. 1, assuming that the geometric center of the playing card is located on the origin O (0, 0) of the rectangular coordinate system, and a proper amount of magnetic material particles are distributed in the playing card, taking the playing card as an example, and taking the length, width and thickness directions of the playing card as the convenience, wherein each direction of the playing card is parallel to the X, Y, Z triaxial directions respectively, at this time, any point a (x 1, y1, z 1) except for the origin is taken on the playing card, a straight line passing through the point a (x 1, y1, z 1) and the origin O (0, 0) intersects with the outer contour surface of the playing card at two points a1 (x 0, y0, z 0) and a2 (-x 0, -y0, -z 0) which are symmetrical about the origin center, taking the total amount of magnetic material particles and/or powder distributed on the playing card as the convenience, counting the total amount of bus segment including the intersection points a1 and a2 and the bus segment containing both ends, and calculating a linear density distribution value n (x 1, y1, z 1) on the length of the segment in the direction, and a linear density distribution value n 1, y1, and a1 are equal to the linear value in the length direction of the line segment is equal to or less than 1; similarly, a straight line passing through any point B (0, Z2) other than the origin and the origin on the Z axis can obtain two points B1 (0, Z0), B2 (0, -Z0) which are symmetrical about the center of the origin and are intersected with the front and back end surfaces of the chess board, and the linear density distribution value n (0, Z2) of the line segment unit length in the Z axis direction can be calculated similarly, if we define the ratio of n (0, Z2) to n (x 1, y1, Z1) as Q ₀ At this time we will turn Q ₀ The discussion of the linear density values on the line segment obtained by connecting points a1 (x 0, y0, Z0) and a2 (-x 0, -y0, -Z0) is obvious, and only shows the distribution condition of unidirectional single magnetic channel in the direction of two-point connecting line formed on mahjong tile by magnetic material particles, while Q ₀ The ratio of two linear density values is the same, and the influence of the magnetic channels on the magnetic force lines passing through the mahjong pieces is comprehensively not illustrated when the distribution trend of the magnetic channels in all directions is different in a macroscopic view. In the same way as above, the channel linear density values of the two-point lines in the Z-axis direction on all mahjong tiles in the Z-axis direction in the generalized way are the same as the linear density values corresponding to the line segments corresponding to the points (0, Z) in the Z-axis and on the same mahjong tile in the same coordinate systemThe ratio of n (x, y, z) generated at any point (x, y, z) and having the same meaning as discussed above is defined as Q, and at this time we call Q the relative linear density value of the thickness direction of the player body and any direction of the player body other than the thickness direction of the player body.

To further illustrate the problem macroscopically, we define n (linear density z) as the linear density value of a single channel along the thickness of the playing piece; n (linear density total Z) is the linear density sum of all magnetic material particles in the thickness direction of the chess and cards along the magnetic wire harness channels with lower magnetic resistance, and the value can reflect the resistance of the chess and cards macroscopic to the extent that the magnetic wire harness passes through the magnetic wire harness in the Z-axis direction, so that whether the magnetic force lines can pass through the magnetic wire harness in the thickness direction more widely without changing the direction is determined, and of course, whether the magnetic wire harness can pass through the magnetic wire harness in the Z-axis direction more widely is also determined not only by the resistance of the magnetic wire harness in the Z-axis direction, but also by the resistance of the magnetic wire harness in other directions.

Similarly, the sum of the values in other directions is the same as the sum of the values in other directions, and the total linear density value of the linear density in other directions except the thickness direction of the chess and card is expressed by n (total linear density x, y, z) in a generalized manner, and of course, a certain single linear density value in other directions is expressed by n (linear density x, y, z).

The following description is made in seven cases.

Namely: setting: q (relative x, y, z) =n (linear density z)/n (linear density x, y, z);

when Q (relative x, y, z) occurs at the ratio:

(a) When the ratio is constantly greater than 1, 1 is greater than or equal to n (linear density z) > n (linear density x, y, z) is greater than or equal to 0;

(b) When the ratio is smaller than 1, 1 is larger than or equal to n (linear density x, y, z) > n (linear density z) is larger than or equal to 0;

(c) When the ratio is equal to 1: then (c 1), 1 > n (linear density z) =n (linear density x, y, z) > 0 (when one of the linear density values in the playing piece is determined, all the linear density values are equal);

(c2) 1=n (linear density z) =n (linear density x, y, z) =1, in this case pure magnetic material particles.

(d) When the ratio is greater than or equal to or less than 1; (d1) When the density is larger than 1, 1 is larger than or equal to n (linear density z) > n (linear density x, y, z) is larger than or equal to 0,

(d2) When 1 is equal to 1, 1 is equal to or greater than n (linear density z) =n (linear density x, y, z) is equal to or greater than 0, and at this time, only the respective pairs of ratios are equal, and the values in the two values of different pairs are not necessarily equal.

(d3) When the density is smaller than 1, 1 is larger than or equal to n (linear density x, y, z) > n (linear density z) is larger than or equal to 0,

(e) When the ratio is more or less than 1: (e1) When the density is more than 1, 1 is more than or equal to n (linear density z) > n (linear density x, y, z) is more than or equal to 0;

(e2) When the density is smaller than 1, 1 is larger than or equal to n (linear density x, y, z) > n (linear density z) is larger than or equal to 0;

(f) When the ratio is greater than or equal to 1: (f1) When the density is more than 1, 1 is more than or equal to n (linear density z) > n (linear density x, y, z) is more than or equal to 0;

(f2) When equal to 1, 1 is equal to or greater than n (linear density z) =n (linear density x, y, z) > 0; at this time, only the value at which the thickness direction is smallest is equal to the value at which the other direction is largest.

(g) When the ratio is less than or equal to 1: (g1) When the density is smaller than 1, 1 is larger than or equal to n (linear density x, y, z) > n (linear density z) > 0;

(g2) When equal to 1, 1 is equal to or greater than n (linear density x, y, z) =n (linear density z) > 0; at this time, only the smallest value in the other direction is equal to the largest value in the thickness direction.

Here, it should be explained that: besides the ratio of the magnetic material particles to the chess board is constantly more than 1 and constantly less than 1 and constantly equal to 1, the following distribution conditions of the magnetic material particles on the chess board are adopted, and the distribution conditions are as follows: the ratio of Q (relative x, y, z) above can be subdivided into: (d) The four distributions (e), (f) and (g), such as (d), on the chess and playing card, the linear density ratio of the channels outside the thickness direction to the thickness direction is larger than 1, or smaller than 1, or equal to 1, and several conditions can exist simultaneously, which completely depends on the two values of the linear density ratio of every two channels distributed randomly, and the conditions (e), (f) and (g) are different and all occur.

In summary, from the overall distribution of seven (except that the tiles are pure ferromagnetic materials) possible to occur in the mahjong tiles, the combination is: except for the seven cases, the (c 1), and (d), (e), (f) and (g) in (a), (b) and (c), the (c 2) case (which is a uniform distribution with constant linear density value equal to 1 in each direction and constant equal in each direction) is reflected to the constituent materials of the chess and card, which is essentially that the whole chess and card body in the prior art is made of pure iron soft magnetic materials. The (c 1) case (i.e. a uniform distribution with equal linear density values in all directions, but the linear density value is always greater than 0 and less than 1), the magnetic material is uniformly mixed in the chess and card body (or a certain range), the magnetic material is not optimally distributed, but is ideal, and can be well utilized, and can be produced by mass injection molding, if (b) case (which is the non-uniform distribution with the linear density value in the thickness direction being constantly smaller than that in other directions) is adopted, the situation can be regarded as the intentionally bad distribution case, but the situation is not suitable, the (a) case and the (f) case (the non-uniform distribution opposite to the (b) case) are more ideal, the magnetic conduction in the thickness direction is only performed by selecting a reasonable structural distribution model, and for (d) case and (e) case, the situation is the distribution case with the linear density value in all directions of the chess being large and small non-uniform or the magnetic conduction in the thickness direction being more random, if the magnetic conduction in the thickness direction is reasonably distributed, the seven cases are also ideal, the situation (a) case (c) and the magnetic force lines in the thickness direction are not easy to change in the directions of the same, and the magnetic force lines in the directions of the chess and the directions are different from the other cases, and the magnetic lines are not passing through the situation is easy to change in the directions of the chess and the two cases, they differ only to a certain extent; (c) The (c 2) condition in (c) is the worse case of the invention, it is easy to change the direction of the magnetic wire beam passing along the thickness direction of the chess and playing card to the directions perpendicular to or approaching to the Z axis, of course, when the (c 1) condition in (c) occurs, the two-phase values of n (linear density Z) and n (linear density x, y, Z) in Q (relative x, y, Z) are equal to or lower than the value between 0 and 1, and it is obvious from the experimental result that the value is approaching 1, the value is approaching to the prior art, the magnetic force effect is smaller, and even the chess cannot be played, and an optimal value is necessarily provided between the two-phase values, which is irrelevant to the principle discussed by us and is not repeated.

The principle of the invention above is elucidated in terms of magnetic physics:

according to the technical means and principle of the invention, the distribution of the magnetic material particles and/or powder bodies on the chess board can be partially continuous or discontinuous, or both, according to the preferable distribution situation, the total linear density value of the distribution of the magnetic material particles and/or powder bodies in the z direction or the direction closer to the z direction is larger than the total linear density value of the magnetic material particles and/or powder bodies in the y direction and the x direction perpendicular to the distribution situation or the direction closer to the y direction and the x direction respectively, so that when the chess board 2 is close to the chess board from the right upper end of the chess board 1 by using a single permanent magnet with N, S polarity, the magnetic material particles and/or powder bodies which are arranged densely along the thickness direction on the chess board are like relay games, the magnetic wire bundles of the single permanent magnet chess 1 can extend to a deeper direction along the magnetic wire bundle channel with lower magnetic resistance in the thickness direction of the chess and the chess provided with more chess and cards which are vertically stacked together, so that the magnetic wire bundles vertically passing through the front end face of the chess and card chess can selectively move the magnetic wire bundles with smaller magnetic resistance and have larger linear density distribution, and the original direction is not easily changed unless the magnetic resistance is smaller in the direction perpendicular to the original direction. In other words, more pieces of chess and cards are penetrated and piled together, so that the magnetic force acts on the lowest piece of chess and cards piled together as far as possible; compared with the prior art made of pure iron, because the magnetic resistance of each direction in the pure iron chess is very small and the magnetic resistance rate is the same, when the operation is carried out in the same way, as shown in figure 3, the microcosmic magnetic wire harness penetrates into the first chess along the direction vertical to the front end face of the pure iron chess 3, and then turns quickly along the direction with the minimum magnetic resistance, namely along each direction in the plane vertical or nearly vertical to the thickness direction on the chess, because air gaps exist among each of a plurality of stacked pure iron chess pieces, the magnetic resistance among the chess pieces is greatly increased, the magnetic resistance of the same distance walked along the X, Y axis direction in the same chess piece is far smaller than the magnetic resistance along the thickness Z axis direction vertical to the chess piece, so that the magnetic force line walks around in the first chess piece to twist a larger direction, and then walks through the second chess piece below, almost all magnetic force lines are gradually changed in direction and shielded in the upper chess and cards, and reflected on the macroscopical aspect, the magnetic force of the chess and cards can not be applied to a plurality of lower chess and cards ideally, so that more chess and cards stacked together are extracted, the situation that the stacked chess and cards are stressed unevenly and are not concentrated, even the chess and cards are scattered instantaneously and are mutually attracted and entangled together can occur, the defect that the pure iron chess and cards are the largest is caused, the great difficulty is brought to quick sorting of the chess and cards, the invention can selectively and easily and stably pick up one chess and card stacked together by using the two chess and cards including the two permanent magnets, or pick up a plurality of chess and cards stacked together without scattering, and easily pick up one of the chess and cards which are laid together and mutually contacted even when playing, the playing card of 4 or 6 piers can be specially used without scattering. The invention is characterized in that the chess and cards are designed into a non-magnetic annular belt structure which is wrapped around the circumference of the front end face of the chess and cards, a layer of magnetic resistance isolation belt which is produced between the flatly-placed chess and cards is also arranged, when the piled mahjong and cards are started, small influence is produced between piers and piers as much as possible, then an auxiliary stand is matched, and then two different permanent magnets of the special chess and cards are matched, one permanent magnet of the special chess and card is a single strong permanent magnet with N, S polarity, the other permanent magnet of the special chess and card is a single strong magnetic induction permanent magnet, at least two corresponding chess or mahjong cards can be sucked, and the other permanent magnet is a set permanent magnet which is formed by more than one rubber magnets which are in multiple particles and have magnetic field acting force distribution areas concentrated on the outer surface of the magnetic rubber adsorption surface.

The following describes the specific embodiments of the chess and card in further detail with reference to the accompanying drawings

Defining the end face of the chess and card: the end faces of the chess and card are the top end face or the bottom end face of the chess and card which are perpendicular to the thickness direction of the chess and card, and the number of the end faces is two; the middle split surface of the chess and card is a middle split surface parallel to the upper and lower end surfaces of the chess and card, and the upper and lower end surfaces of the chess and card are symmetrically distributed on two sides of the middle split surface of the chess and card. The split surface of the chess and card divides the chess and card into an upper half surface and a lower half surface which are symmetrical.

Example 1

Taking a round playing card as an example, as shown in fig. 4, the playing card 2 includes a sheet playing card made of a non-magnetic material, such as a wooden material, and soft magnetic spherical particles 4 are embedded in the playing card 2, specifically soft magnetic iron spherical particles 18 with diameters less than half of the thickness of the playing card are embedded in the playing card (here, the number may be small, and as long as the volume is not out of limit, the playing card can be one or only one sheet or one sheet is not limited, and only the illustration is given here). The upper half of the chess board is 9 pieces, and the lower half is 9 pieces. One of the upper half 9 grains is positioned on the upper half of the geometric center shaft vertical to the chess and card front end surface 5, the other 8 grains are uniformly distributed on the circumference of the same plane which takes one grain on the geometric center shaft as the center of a circle and takes the half of the radius of the round chess and card as the radius, and the surface of the circumference is parallel to the chess and card front end surface. The 9 grains on the lower half surface and the 9 grains on the upper half surface are symmetrically distributed on two sides of the split surfaces of the chess and cards one by one, and are arranged between the upper end surface and the lower end surface.

The specific dimensions of the chess and card are as follows: the thickness of the chess and card is 1.1mm, and of course, the thickness can be slightly more than 0.1mm or increased to approximately 7.5mm, and other parameters can be correspondingly adjusted at the moment. The diameter of the soft magnetic iron spherical particle body is 0.54mm, and the chess board can be a go piece with the diameter of 1.8 cm or a Chinese checkers piece with the diameter of 1.3cm, or a chess or Chinese chess piece with the diameter and the thickness respectively increased to 2.5 cm and 0.25 cm.

Example 2

The go chess pieces are shown in fig. 5, and the later-mentioned go chess pieces and mahjong pieces also comprise another mahjong piece in fig. 6, and the structure of the go chess pieces is the same as that of the go chess pieces in fig. 5, and the differences are only that the appearance is different, and the functions are also different; the method for manufacturing the go pieces with the thickness of 0.5mm-3mm and the method for manufacturing the go pieces, the chess pieces and the mahjong pieces with the thickness of 0.1mm-7.5mm can be expanded, and the embodiment is only described briefly, and the specific production size and the production method of the go pieces can be adjusted according to the actual production process conditions and the method operation. The method comprises the following steps: taking a soft magnetic ferrite powder as a magnetic material, and taking a thermoplastic or thermosetting plastic as a non-magnetic material: polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyformaldehyde, polycarbonate, polyamide, acrylic plastics, other polyolefin and copolymers thereof, poly mock, polyphenyl ether, chlorinated polyether or thermosetting plastics, such as phenolic aldehyde, formaldehyde, melamine formaldehyde, epoxy, unsaturated polyester, silicone and other plastic particles, are uniformly mixed according to a certain proportion, after the injection molding condition is met, go pieces with certain thickness and shape and size are injected by an injection molding machine, the go pieces or mahjong piece blanks are made into the same shape as the known shape of various kinds of the go pieces, namely the go pieces and piece blanks 6, the external contour lines of the go pieces or rectangular mahjong piece blanks are respectively surrounded on the basis of the go pieces, the go pieces or the rectangular mahjong piece blanks, annular thermoplastic plastics 7 with the same thickness as the go pieces, the mahjong pieces or the piece blanks are wrapped, the wrapping width is 0.4cm-0.6cm, the width is only used as an illustration of the injection molding condition, the go pieces or the mahjong pieces are made into the mahjong pieces or the mahjong pieces, the mahjong pieces or the mahjong pieces are not required to be mixed with the weight of the mahjong pieces or the mahjong pieces, the mahjong pieces or the mahjong pieces and the mahjong pieces are not required to be tested, and the weight of the mahjong pieces or the mahjong pieces are not required to be tested, and the weight of the mahjong pieces is not required to be compared with the mahjong pieces or the blanks, and the weight is determined, and the weight of the mahjong pieces is required to be tested, and the weight is not required to be compared with the weight to be the pieces or the pieces and the blanks to be tested; the weiqi pieces, the pieces of the weiqi or the blanks of the mah-jong pieces can also be all formed by soft magnetic ferrite powder bodies.

Example 3

The difference from example 2 is that the magnetic material is a soft magnetic ferrite powder body after being uniformly mixed with a trace amount of hard magnetic material powder body which is not magnetized, and the hard magnetic material powder body may be a hard magnetic ferrite powder body; such as alnico, feco, and fecr, baFe12O19 of barium ferrite, etc. The difference from example 2 is that a process of magnetizing N, S polarity is added to all mahjong tile blanks of the same specification along the thickness direction of the mahjong tile before the mahjong tile blanks formed by injection molding are solidified, so that mahjong tiles with extremely weak magnetic attraction or magnetic repulsion between the tiles when stacked in the same direction or in opposite directions after solidification are obtained.

The mahjong tiles are magnetized in the same polar direction in the vertical direction on the front end face or the back end face, so that mahjong tiles with slight adhesion attraction can be obtained when the mahjong tiles are piled together in sequence on the same end face, and the amount of hard magnetic materials doped into the mahjong tiles is controlled to be far smaller than the gravity of the mahjong tiles and the magnetic attraction of corresponding mahjong tiles. Thus, the adhesion attraction force or repulsion force can be considered to be very small compared with the gravity force or the attraction force of the chess. The front end face is the face with characters or patterns on the mahjong, and the back end face is the face symmetrical to the front end face of the mahjong about the middle of the mahjong.

The method has the beneficial effects that when the playing pieces are lifted by the pier, when the magnetic poles of the permanent magnets of one end of the adsorption surface of the playing pieces are different from the magnetic poles reversely buckled on the back surface of the tabletop mahjong pieces, the pier mahjong pieces reversely buckled on the tabletop can be ensured, the number of the pier mahjong pieces sucked up at one time is more firm, and meanwhile, when the playing pieces are arranged between the hand, the two mahjong pieces are messy piled together, and when the same end surfaces of the two mahjong pieces are opposite or are opposite, the two mahjong pieces are mutually exclusive and are easier to separate. Naturally, the number of the mahjong tiles which are sucked at one time can be correspondingly reduced when a plurality of mahjong tiles which are piled up with the right end faces upwards are picked up by using the chess-playing tools, but the problem is that the substantial use condition of the mahjong tiles is not affected as long as the number of the hard magnetic powder and the magnetizing are properly controlled; in contrast, when the hard magnetic materials are mixed together in the chess and cards, the application situation is complicated, but the soft magnetic materials and the hard magnetic materials are charged and not magnetized and can be acted by the action of the permanent magnet, which is just the basis that we avoid the shortages of the materials by utilizing the advantages of the soft magnetic materials and the hard magnetic materials, and if no action is acted, the materials are never used as a talk. For hard magnetic materials, this is not the main flow direction of our application and will not be described in detail.

The above 3 examples do not cover the seven structural distributions of the magnetic material in paragraph [0009] of the present invention, and here, in order to explain the theoretical rationality of the seven distribution modes in detail, the description will be given below in terms of a model method only in terms of distribution principle, but not in terms of others, and the models must have practical applicability; for ease of understanding, certain structural distribution models may be limited from three-dimensional space to a certain vertical plane defined by the Z-axis and any line intersecting the Z-axis, and may be collectively described as the following distribution models. As shown in fig. 7 (i-vii), assuming that the model is a mahjong tile, and the geometric center of the mahjong tile is located on the original point O (0, 0), the length, width and thickness dimensions of the mahjong tile are respectively (3, 2.1 and 0.27) cm, and the triaxial directions are respectively the same as the length (X-axis), the width (Y-axis) and the thickness (Z-axis); the nonmagnetic material is any one of common organic glass, and then: the first model example (I) (hereinafter, described in order) corresponding to paragraph [0009] is; in any vertical plane containing the central Z axis of the mahjong, at the central origin of the mahjong, embedding a pure iron ball particle w with the unit length of 0.03 cm (the iron ball particles of the seven models are the same), so as to meet the structural distribution condition of (a) that the ratio of Q (relative x, y, Z) =n (linear density Z)/n (linear density x, y, Z) is constantly greater than 1 in the analysis of the specification; the model example (II) is: in a plane perpendicular to the central Z axis of the mahjong tile and containing an X axis and a Y axis, along a certain direction in the limited plane of the mahjong tile, inserting H (H is a positive integer greater than 0) straight iron ball particles with linear density values of 1 in close proximity and side by side, and enabling the linear density value of the ball particle surfaces formed by the channels arranged in the plane to be equal to 1 constantly no matter which direction in the plane is calculated; the distribution of (b) in the analysis Q (relative x, y, z) was satisfied, wherein the maximum unit length of the spherical particles was taken to be 0.03mm (conclusions were confirmed later); the model (III) is: in any vertical plane containing the Z axis, N (wherein N is a positive integer greater than 0) linear density values are arranged at equal intervals along the thickness direction of the mahjong tiles. The linear density value of the lower magnetic resistance magnetic wire bundle channel formed by uniform pure iron ball particles (the size of the ball particles can be infinitely small) is simultaneously equal to n when any lower magnetic resistance magnetic wire bundle channel in any direction in the plane is arranged. In this way, the linear density value of the spherical particles of each channel in other directions of other planes after rotation around the Z axis is eventually made to be identical to n. And is equal to n. The process is a mixing process, (wherein 1 is more than n and more than 0, in actual operation, the process is called 'setting', namely, pure iron ball particles are scattered and uniformly mixed and distributed, the smaller and more uniformly mixed iron ball particles are, the more macroscopically the linear density values in all directions can be kept constant to be a certain linear density value n, and only a structure schematic diagram of a certain S surface after the uniform structural distribution in any vertical plane magnetic material containing a Z axis is intercepted, wherein the example satisfies the (c 1) distribution condition of (c) in Q (relative x, y and Z); model (iv)) is: in at least one vertical plane containing the Z axis, along any direction outside the Z axis and the Z axis respectively, embedding two pure iron ball particle channels with low magnetic resistance and linear density values of 1 and 0.3 respectively (see figure 7 IV) and I1, I2, I3 and I4 respectively, namely satisfying the (d) distribution condition in Q (relative x, y and Z); the model (V) is: in at least one vertical plane containing the Z axis, along any direction outside the Z axis and the Z axis respectively, embedding two magnetic wire harness channels with low magnetic resistance, which are respectively formed by pure iron ball particles and have linear density values of 1, 0.6, 0.9 and 0.3 (see figure 7V), into the magnetic wire harness channels respectively, namely satisfying the distribution condition of (e) in Q (relative x, y, Z) (wherein the data of the two directions can be oppositely arranged); model (vi)) is: in a three-dimensional space of an X-axis and a Y-axis and a Z-axis contained by the mahjong, N magnetic wire harness channels with lower magnetic resistance and formed by pure iron ball particles and with linear density values equal to 1 are arranged side by side in a line manner in parallel to the Z-axis direction, namely the distribution condition (f) in Q (relative X, Y and Z) is satisfied, wherein N is the number of vertical channels larger than 1 and is a positive integer, (see figure 7 VI); the model (VII) is: selecting a Z-axis direction as a mahjong tile thickness direction in a three-dimensional space containing an X-axis and a Y-axis of a mahjong tile, and setting P (P is a positive integer larger than 0) magnetic wire harness channels with linear density values of 1 in parallel one by one on a limited mahjong tile along the X-axis direction in a plane which is perpendicular to the Z-axis direction and contains the X-axis and the Y-axis, wherein the magnetic wire harness channels with lower magnetic resistance are formed by pure iron ball particles with the size of 1 unit volume (the unit length is 0.03 mm), and the linear density values of all channels arranged on the plane are constantly equal to 1 no matter which direction is calculated from the plane; the above-mentioned conditions are changed so that the dimensions in all directions in the above-mentioned plane are infinitely extended and at the same time all the spherical particles in the plane occupy all the spaces, and at this time, the model (VII) is the desired model structure distribution, and it is proved that on any spherical particle on the spherical particle face of the model, the linear density value calculated by the passage through the spherical particle plane along the limited thickness direction and passing through the spherical particle is smaller than or equal to the linear density value of all the passages through the spherical particle plane, wherein the direction equal to the linear density value is the direction perpendicular to the axis by 90 degrees except the thickness direction of the spherical particle, and is larger than all the directions except the directions, and the model satisfies the distribution of (g) in Q (relative x, y, z).

Demonstration process for model (II), model (VII) conclusions: assuming that a miniature mahjong model with length, width and thickness of 7 times 5 times 3 units is selected, (the volume is small, the data is simple only as theoretical evidence), the center of the mahjong is located on an original point, the length, width and thickness directions and X, Y, Z three axes are respectively in the same direction, at the moment, 7 times 5 magnetic particles are respectively paved on the middle split surface of the mahjong containing an X axis and a Y axis along the directions of the X axis and the Y axis, and the single magnetic particle is a magnetic square particle with side length of 1 unit length, so that a model mahjong with interlayer thickness of 3 units is prepared, and as shown in fig. 20, the straight lines Z0 on the H and G plus Z axes are known to be three lines respectively and simultaneously encircling H in the figure. Origin O, G ₀ Three parallel lines rotating at three points, the area sandwiched by the H and G lines is an area channel formed, and the angle a is a clockwise included angle generated by rotation of Z0 around an origin O (0, 0) and the Z axis, wherein c, b, e, d, G is a triangle NPQ and a triangle MG respectively ₀ NP, QP, NQ, MP, G of P ₀ Q eachLength of line segment, wherein each line segment added absolute value represents length of each line segment, |MG ₀ As long as 1, triangle MG is known from trigonometric function and plane geometry principle ₀ Under P cover (g+b) =1/cosa, so triangle MG ₀ P under cover->And (3) the same principle: triangle NQP +.>Also, because |nq|/1=b/(g+b) =bcosa, |>Triangle NQP Wherein the method comprises the steps ofIn fact, according to the definition of the linear density of the present invention, it can be deduced that the calculation formula of the linear density value of each channel in each direction in the vertical plane of the present mahjong tile including the X axis and the Z axis (only considering the case of a section plane of one unit thickness here) is as follows: (note: the volume numbers of the upper two triangles are the values of the magnetic particles corresponding to the part of the scanned channel after the rotation of the angle a, and the channel length corresponding to the angle a is changed along with the angle a, and the two cases are (a): 3/cosa: (b): 7/sina, as can be seen from the figure, when the dimension of the model in the X-axis direction is a finite value, the linear density value should be calculated in two segments):

the above is a piecewise function: solving equation (1/cosa) - (3/sina) =0

Simplified to tga=3, obtainable: a=arctg 3, slightly less than 72 degrees.

Namely: when the angle a is smaller than a=arctg 3, the linear density is calculated by the formula N1, and when the angle a is larger than a=arctg 3, the linear density is calculated by the formula N2;

from the above, the line density values of the channel at several specific angles a in the Z, X vertical plane can be calculated, and meanwhile, the change curve of the line density value with the angle a can be deduced (similarly to the calculation of the cross-section plane along the Z, Y direction): when a=0, the linear density value is 1/3; a=30 degrees, a=45 degrees, a=arctg 3/2, a=60 degrees, a=arctg 7/3, a=arctg 3, a=75 degrees, the linear density values are 0.3847, 0.4713, 0.4620, 0.4553, 0.4377, 0.5421, 0.6332, respectively; when a approaches 90 degrees, for example, cos (a) =0.01, the corresponding sin (a) =0.9999995 is obtained by the formula N2: n2 (approaching 90 degrees) = 0.9870935 can prove that the limit value at a=90 degrees is 1; the above a=arctg 3/2, a=arctg 7/3, a=arctg 3, and several points are special points under the present model condition, a=arctg 3/2, a=arctg 7/3, and a=arctg 3 are the intersection vanishing point of the channel line G and the upper plane line segment of the present mahjong tile, and the boundary line where the longest channel line of the present mahjong tile and the triangle NQP start to appear, respectively, it is obvious that when a=arctg 7/3, the minimum linear density value 0.4377 after having an angle of a=60 degrees is corresponding, and then as a increases, the linear density value increases rapidly, from the above a angle changing from 0 to 90 degrees, the linear density value changes, and it is known that the linear density value is minimum 1/3 in the thickness direction, slowly increases to 0.4713, then decreases to 0.4377, and then increases rapidly to 1.

Conclusion (a): according to the formulas N1 and N2, when the mahjong tiles are in the limited space condition, the linear density value of each channel line in the Z-axis direction on the mahjong tiles is smaller than the linear density value of any channel in any direction other than the Z-axis direction, namely: except for the direction of the Z axis (thickness direction) which is the minimum value, namely, the linear density values of all other directions are larger than the linear density values of the channels in the Z axis direction, and the directions of the minimum and maximum linear density values of the other directions are the directions which are adjacent to the Z axis and perpendicular to the Z axis, the conclusion can be proved by an N2 type curve; (b): when the size of the chess board X, Y is increased to infinity and the magnetic particle plane perpendicular to the Z axis is also enlarged to infinity, at the moment, the linear density value of each channel corresponding to each direction in the plane is equal to the linear density value of any channel in the Z axis direction, the linear density value is the minimum value, the value is determined by the N1 formula, the corresponding a=90 degrees, and the limit value is equal to 1/3 as known in the example; the conclusion of (a) and (b) above satisfies the distribution of model (II) and model (VII) in paragraph [0009 ].

All distribution conditions of the model (I-VII) are suitable for various distribution requirements in the [0009] section, and the model (I) is obvious that only the total unit length in one direction on the Z axis is shortest, the total unit length in any other direction is larger than the total unit length in the Z axis, and the distribution conclusion of the model (I) is required to be met according to the definition of linear density; models (iv, v, vi) are shown in fig. 7 (iv) with I1, I2, I3, I4, and fig. 7 (v) with J1, J2, J3, J4, where i1=i3=1, i2=i4=0.3, I1 > I4, I3 > I2; j1 > J3, J4, J3 > J2, the linear density values of J1, J2, J3, J4 in fig. 7 (v) are not equal, while the N channels arranged side by side in the thickness direction in fig. 7 (vi) have the linear density values equal to 1, when the line between the head and tail end points of any two channels in the vertical direction is taken and the linear density value of the channel is calculated, it is obvious that the linear density values are equal to 1 and also equal to the linear density value of each of the above arranged thickness directions, but these directions are not the thickness directions, and of course, the other line channels have the linear density values smaller than the thickness direction; the model (III) is obvious and will not be described in detail here.

In the following, the case when the thickness of the chess and card is less than 3-5.5mm, especially less than 3mm is discussed, the chess and card is not easy to pick up due to the reduction of the thickness of the chess and card, and the game can be played by using auxiliary tools during the game. The chess comprises at least two chess permanent magnets, and the number of the chess permanent magnets which can be maximally picked up by the at least two chess permanent magnets is different.

The chess comprises two chess permanent magnets and a connector for connecting the two chess permanent magnets; the magnetic field distribution of the magnetic field of the magnetic pole adsorption end face is more concentrated, and the magnetic force lines of the magnetic field are strong permanent magnets which have the ability of passing a longer distance along the thickness direction of at least two chess pieces vertically stacked together. The strong permanent magnet is a single strong magnetic induction permanent magnet, and the magnetic induction intensity is enough to suck at least two chess and cards vertically stacked together at one time; the permanent magnets with uniform magnetic field distribution are magnetic rubber permanent magnets or magnetic plastic permanent magnets, and can only attract one or a single permanent magnet of at least one chess and card vertically stacked together at a time.

The connecting body is a finger stall which can be sleeved on the fingers of a person, and the strong permanent magnets and the permanent magnets which are distributed uniformly are arranged on the finger belly and the finger back of the finger stall. The finger stall is an annular or ring-like finger stall, and the annular or ring-like finger stall is formed by a non-magnetic material body which can be deformed and bent into the finger stall or is hinged into the finger stall in a plurality of sections.

Working principle of chess

In order to better explain the working principle of the present invention, firstly, the magnetic rubber body used in the present invention and the magnetic field distribution characteristics of more than one permanent magnet aggregate contained therein are described, see fig. 8, fig. 8 is a top enlarged view of the magnetic rubber adsorption surface 9, each small particle permanent magnet 10 on the outermost surface layer of the magnetic rubber body along each position of the surface layer surface is set (assuming that the magnetic pole distribution is enlarged to be visible) in each position in each direction of the surface layer surface, the magnetic pole distribution of the small particle permanent magnet regularly shows N or S polarity with certain same orientation, and the magnetic field direction is perpendicular to the magnetic rubber adsorption surface 9, which can be achieved by controlling magnetization in the manufacture of the magnetic rubber, then, small dots are set as the direction of north magnetic lines when the magnetic lines of force N pass out of the paper, and the "X" crosses as the direction of south magnetic lines of force pass through the paper, and fig. 9 is an equivalent bar-shaped small magnet schematic view perpendicular to the magnetic rubber adsorption surface. In order to clearly see the distribution trend of magnetic force lines on the surface of the magnetic rubber, the part a of fig. 9 is enlarged, as shown in fig. 10, which is a schematic diagram of the distribution of magnetic force lines in the magnetic rubber adsorption surface 9 along the enlarged cross section of the equivalent bar-shaped small magnet 11 cut by any section perpendicular to the adsorption surface, wherein each of the adjacent equivalent bar-shaped small magnets 11 with directivity in fig. 10 is a magnetic field distribution common to all the equivalent bar-shaped small magnets under any cutting line on the surface of the adsorption surface, and a magnetic field similar to the section of fig. 10 is distributed on the surface of the magnetic rubber adsorption surface 9 in any direction, and the characteristics are that: the magnetic lines of force are in the direction along the magnetic rubber surface and vertically outwards from the magnetic rubber surface, and are all microcosmic small-particle permanent magnets 10, and firstly, the directions of the main magnetic lines of force of the magnetic lines of force are all along the vertical direction of the adsorption surface, but the magnetic paths corresponding to the magnetic fields of the magnetic lines of force are limited in walking range due to the fact that the particles of the magnetic lines of force are too small, and the external space is tightly attached to chess and cards on the adsorption surface, so that the range of acting force is limited, and the magnetic lines of force are generally limited to chess and cards attached to the chess and cards; secondly, the acting force of the two plates is the group resultant force on the adsorption surface, and the aim is achieved as long as the group resultant force is larger than the gravity of a single chess board. The game is one of special functions and characteristics different from the prior art, and is mainly used for playing chess or mahjong, while the other permanent magnet is mainly used for arranging and playing mahjong between offices; in practice, the game is a combination of two permanent magnets. In this case, macroscopically, compared with the microscopic dimensions of the powdery small micro-particle permanent magnets, the linear dimensions of the thickness dimensions of the playing pieces are large, and it is obvious that the magnetic field diverges to the magnetic line space range of the space outside the adsorption surface, from the N pole, to the nearby space, and into the playing pieces in contact with the N pole, and the magnetic lines of the final magnetic field enter the playing pieces in the outer space forming the magnetic circuit path, and the distance of the total magnetic circuit of each small micro-particle permanent magnet is very small compared with that of the other monomer magnetic induction permanent magnet in the outer space, so that (depending on the density and magnetizing intensity of the magnetic particles of the magnetic rubber, the magnetic circuit can be controlled) the magnetic circuit is only relatively uniformly distributed on the surface of the magnetic adsorption surface, and is not easy to penetrate the uppermost playing piece placed together to enter the next playing piece, therefore, the magnetic acting force can not be easily acted on the outside of the first chessmen which are piled together, the magnetic rubber permanent magnet can only pick up one chessman which is contacted with the interface, on the contrary, the magnetic force line distribution test action range of the magnetic force line of the magnetic pole adsorption surface of the single strong permanent magnet can be compared with the magnetic force line distribution test action range of the magnetic pole adsorption surface of the magnetic rubber permanent magnet because of the magnetic induction intensity and the direction concentration of the magnetic force line of the other single strong magnet, and the magnetic conduction effect of the magnetic wire harness channel with lower magnetic resistance is distributed along the thickness direction of the chessman, at the moment, the magnetic conduction in other directions is weaker, when the chessman is picked up, the distance that the magnetic force lines penetrate along the vertical direction of the chessman surfaces which are piled together is longer, obviously more than a plurality of times of the distance of the thickness dimension of the chessman, and the magnetic force line distribution test action range of the magnetic pole adsorption surface of the single strong permanent magnet can be obtained, for the single strong permanent magnet, the force can easily act on more than one chess and card piled together, and the force can act on the central area of the chess and card with the distribution characteristic of the invention more intensively and uniformly, the direction is along the direction perpendicular to the positive or negative end surfaces of the chess and card and faces the adsorption surface of the chess and card, in other words, most of the magnetic force lines of the magnetic rubber are distributed on the shallow surface layer contacted with the chess and card by the magnetic rubber, and as the magnetic loop travel of the magnetic rubber is smaller than that of the other strong magnet, the magnetic loop travel of the magnetic rubber cannot effectively act on the plurality of chess and card piled together, so that the magnetic force cannot act on the other chess and card piled together, only one chess or mahjong contacted with the strong permanent magnet can be singly lifted, and the strong permanent magnet can vertically penetrate the adsorption surface contacted with the chess and card along the N-pole direction far (compared with the prior art, when the distance is larger than the multiple thickness dimension of the chess and card, the magnetic force lines can attract a plurality of chess and card piled together by the magnetic force.
