JP6575802B2 - Anti-turning support for book stand, placement stand for book stand and USB stand scanner - Google Patents

Description

  In response to the inconvenience of turning pages naturally when the hand is released, the book stand is improved so that the book spread is stopped on the top and bottom, and the book for optimally photographing the spread with the USB stand scanner based on the result. This is related to the structure of the viewing platform and the arrangement of the USB stand scanner.

The book stand is described below as a book stand that can also be used for a USB stand scanner. The usage of the scanner related to this case is as follows.
(1) Place the book spread under the desk lamp reading sensor of the scanner, correct the subject's proper position while looking at the computer screen, shoot and save it on the computer, and then need a screen to save it Depending on the size, enlarge, reduce, scan and other edits.
(2) The spread may be directly enlarged on the personal computer screen and used instead of the magnifying glass.
{Circle around (3)} When turning the pages of a book and continuously shooting and saving the spread, the shooting button is pushed on the software at the set time interval, and the page is turned at the time interval.

Conventionally, when a book spread of a book whose pages are naturally turned easily is photographed while holding the spread with both hands, there are the following problems.
{Circle around (1)} When shooting continuously, page turning and positioning are performed within a set time interval, so that the work requires a certain level of skill and variation in the image occurs.
(2) Since the left and right edges of the spread are grasped by hand or pressed onto the table, the spread is not flat, and the characters in the image near the binding and the left and right outer edges are easily distorted and light and dark. Characters are difficult to read.
(3) Since the spread is held with both hands, there is an inconvenience that the personal computer cannot be operated by hand during that time.

  Problems such as those described above can be greatly improved by holding the appropriate writing stand and appropriately arranging it with the USB stand scanner.

The requirements of the reading table which improves the above-mentioned problems and has other necessary requirements and the arrangement table for properly arranging the scanner are as follows.
(1) The USB stand scanner is placed on the top side of the double-page spread, and in the case of the largest version of the book where the application of the scanner is set, the front of the leg may coincide with the top side of the double-page spread, depending on the model. Need to be placed close to each other.
(2) The bar-shaped reading sensor is arranged in the vertical direction at the center of the spread.
(3) The turn-up stop of the reading stand does not protrude from the margin to the inside.
(4) The spread surface is as flat as possible including the vicinity of the binding portion and the vicinity of the left and right outer edges.
(5) A single unit can be applied to various book sizes.
{Circle around (6)} Page turning is easy and quick, and the spread is surely maintained.

Conventionally, various books have been proposed for reading books, but by turning the edges of the spread side and the top side of the book with a turn stop, the turn of the book can be completely stopped. The structure is designed so that it can respond to the effect of changing the size of the book, and the structure that the turning stop rotates around the shaft center can be applied to a wide range of book thickness, making page turning easy and quick. A table is disclosed in [Patent Document 1].
Patent No. 5257808

  In addition to the features described in [0006], the book counter according to the above document allows the restraint height to be adjusted within the range in which the restraining force of the turning stop does not exceed the repulsive force from the facing surface. Compared to the case of holding, it is expected that the flatness of the spread surface can be adjusted to some extent and the photographed image is good. In addition, if the leg of the USB stand scanner is arranged on the top side of the spread book with the top and bottom direction of the book placed on the book stand being reversed, the plate of the backing plate provided on the ground side by the structure of the book stand The leg end of the scanner can be positioned close to the top edge of the spread at a distance of thickness. Moreover, even if the top-and-bottom direction is reversed, it corresponds to a wide range of book sizes as described in [Patent Document 1], the page can be turned quickly, and the spread is surely maintained. As a result, it is expected that the book can be used as it is for a USB stand scanner if the top and bottom direction of the book placed on the book table is reversed.

  However, although the book stand is not inconvenient for reading, there are the following problems to obtain a stable spread surface with as little flatness as possible for a USB stand scanner and little variation in page turning.

  [Patent Document 1] Claims 1, 7, and 8 of Claim 1, 7 and 8 The restraining force for holding the facing surface by turning over the support for turning up is the turning radius of the friction surface that generates the couple that forms the turn. Since the force is reduced by the lever ratio with the rotation radius of the stopper, there is a limit to increasing the frictional force of the friction surface for obtaining flatness in the vicinity of the binding portion that requires a particularly large restraining force for the USB stand scanner. The frictional force must be actuated for each page turn, and if the frictional force is increased, there will be variations in the restraint height due to wear of the part and changes in the frictional force over time, and a stable spread surface cannot always be obtained as a photographing surface. .

  Further, as a correspondence to the size of the book plate to be placed, the book stand described in [Patent Document 1] corresponds to the size of the book plate placed according to claims 2, 3 and 4. This is dealt with by changing the top-to-bottom position of the top-side turn-stop, and when storing it, the position is reduced to the ground side and the vertical direction is made smaller. It has not been.

  A novel anti-turn support that improves the conventional problems as described in [0009] and a book spread with a USB stand scanner that satisfies the requirements as described in [0005] As well as an arrangement table for optimally arranging the reading table and the scanner for the photographing, and reducing the horizontal direction of the reading table as described in [0010]. For this purpose, the following is proposed for a book cradle that can be stretched horizontally.

  In order to improve the problem as described in [0009], the invention of claim 1 does not require the frictional force of the rotating surface for restraining by turning up the spread of the book placed on the reading table, The vertical position of the turning stop can be adjusted, and the turning stop is related to the turning stop support so that the turning stop does not hinder page turning.

  The turn-stop support is a strip-like columnar plate that is located on the top or bottom of the center of the book cradle, or on either side of the book cradle. A strip-shaped attachment plate is attached to a lower end of the attachment plate so as to face each other so as to be rotatable in the vertical direction by a hinge or a shaft and a bearing.

  Furthermore, there is an anti-turn support plate that is in contact with the mounting plate so that the position of the attachment plate can be adjusted in the vertical direction by mutual guide means provided on the side that does not face the columnar plate. The arm has a pair of arms extending left and right, and a pair of plate-like turning stoppers at both ends of the arm. The turn-stop support plate extends from a vertical hole provided in the center in the vertical direction and is attached to a screw that is screwed to the mounting plate, or extends from both the left and right sides of the turn-stop support plate. The mounting plate is held by the mounting plate so as to be slidable in the vertical direction by a frictional force generated by any spring force of an elastic body provided so as to face the contact surface.

  The mounting plate is rotated together with the turn-up stop support plate to a position facing the columnar plate, and a convex portion or a concave portion provided on the columnar plate by an attracting force of a permanent magnet fixed to one of the facing surfaces. Is joined to the concave or convex portion provided on the mounting plate, whereby the turn-up support plate is held upward together with the mounting plate on the columnar plate, and the turn-up stop is located at the position of the arm. From the mounting position, the outer sides of the left and right sides of the columnar plate extend further in the vertical direction from the standing position of the columnar plate and face the book cradle.

  As described in [0014], with the mounting plate held by the columnar plate, the up / down position of the turn-stop support is corrected as described in [0014] and the turn-stop is placed on the book cradle. It is made to constrain the edge of the spread heaven, the ground side, or any one of them to an optimum height.

  When using only the top or the ground side for the turn-up support, the configuration on the other side is not specified, but there is a backing plate that abuts the edge of either the spread top or the ground side. And the structure which has a turning stop which restrains the said edge part so that vertical position adjustment is possible is desirable.

  When turning the page, remove the system of the concave and convex portions as described above, or rotate the turn-stop support plate backwards so that the turn-stop is from the position where the paper sheet passes. Retreat so that it does not interfere with page turning. Move the paper sheet in the direction of turning left and right, and rotate the anti-turn support plate upward while holding the facing surface with one hand, and the facing surface will be the previous page due to the adsorption of permanent magnets or the combination of concave and convex parts One cycle of page turning is completed in the same manner as in the case of the two-page spread.

  Since it is configured in this way, either the spread top or the bottom of the book placed on the reading table is restrained using the curl stop support, and the operation of a large frictional force is not necessary for restraint. There is no problem of friction life, and the optimum restraint height can be set, the restraint height does not change with each page turning, and turning is not hindered by turning operation, so page turning is easy and It can be implemented quickly.

  In the invention of claim 2, as a book stand having the characteristics necessary for a USB stand scanner as described in [0005], a turn-up stop that can be adjusted in the vertical position to constrain the top edge of the spread of the book to be placed. A combination of a turn-up stop by the turn-up stop support body according to claim 1 that restrains an edge on the ground side and a sliding plate that enables adjustment of the position of the turn-up stop support body on the ground side in the vertical direction. It is related to the structured book stand.

  The book stand has a concave groove into which a binding portion of a book to be placed is inserted in the center top and bottom direction of the book cradle and projects upwardly in contact with the center top end of the book cradle. A contact plate that receives the top end side of the spread, a top mounting plate fixed to the back of the top of the corresponding plate, and in contact with the back of the top of the top mounting plate. A pair of plate-shaped left and right turn-stops facing a book cradle that have a pair of arms that face the guide so that they can move up and down and extend from both sides to the left and right. A plate mounted on a screw that has a vertically long hole in the center vertical direction and that passes through the hole and is screwed to the top mounting plate. Enclose the top mounting plate by extending from the left or right side of the spring or the top side turn-stop support plate. The top-side mounting plate is placed in the optimum vertical position with a force that is greater than the repulsive force that the turning stop receives from the spread due to the friction force generated by the mutual sliding surfaces that is pressurized by any of the provided elastic bodies. To be held.

  With such a configuration, the top-side turning stopper holds the top-side edge of the spread spread at an optimal restraint height, and the USB stand scanner is arranged on the top side of the book stand, and the leg of the scanner is It can be installed close to the top edge of the book spread to be placed at a distance of the thickness of the backing plate.

  On the other hand, a vertically long sliding plate is fitted in the concave groove, a vertically long hole is provided in the bottom of the concave groove or the sliding plate in the vertical direction, and the sliding is performed by a screw or a columnar member penetrating the hole. The sliding plate is held by the bottom of the concave groove and is slidably positioned in the vertical direction by being pressed by the spring force of the elastic body mounted opposite to the contact surface between the plate and the concave groove bottom. The

  There is a columnar plate that is added to the ground side end of the sliding plate, protrudes upward, has a surface facing the top and bottom, and forms an L-shaped member together with the sliding plate. The turn-up support according to claim 1 is attached. In this case, the columnar plate is the same as the columnar plate described in claim 1.

  The ground-side edge of the book spread is constrained by the flip-stop retained by the flip-stop support body positioned in the top-bottom direction by the size of the book plate placed by position adjustment by the sliding plate. The procedure for restraining the edge of the spread by the turning stop is described in [0014], [0015], and [0016]. When the book stand is stored, the sliding plate can be moved in the top direction together with the turn-up support, thereby making the vertical direction of the book stand small.

  As described above, the spread of the book in which the top and the edge of the ground side are constrained on the book stand is photographed by the USB stand scanner placed together with the book stand on the placement stand according to claims 4 and 5 described later. To be served.

  Next, the procedure for turning the pages will be described. First, the ground-side turn-stopping support plate is removed when it is held by the permanent magnet, and is removed when it is concave or convex. Then, after manually rotating to the stopper position provided below, the paper sheet to be turned is moved to the lower part of the left and right turning stops on the top side. Next, the ground-side turn-stop support plate is rotated upward, and the ground-side turn-stop support plate is held on the columnar plate by adsorption of the permanent magnet or by the combination of the concave and convex portions. In this state, the turning of the heavens and the ground side is constrained to the spread heavens and the edge of the ground side, and the page turning is completed.

The bookstand described in this claim has been improved as follows with respect to the bookstand described in [Patent Document 1].
(1) A large frictional force during the turning operation for turning over is no longer required, and the problem of frictional life due to this operation is eliminated.
{Circle around (2)} The restraining force for turning over is no longer insufficient, and the required flatness in the vicinity of the spread binding portion and in the vicinity of the left and right outer edges can be obtained.
(3) There is no variation in the restraining height of the turning stop for each page turning, and a photographed image with little variation can be obtained.

  Also, when the book stand is used for reading, the reading side is generally used with the top side of the facing spread being inclined upward, and the sliding plate is moved in the vertical direction depending on the size of the book. The flip-up stopper arranged at the end of the sliding plate is inconvenient in installation posture unless the top side of the spread is constrained. This arrangement is the same as the book stand described in [Patent Document 1], although there is no inconvenience for reading, although the top and bottom direction of the spread arrangement is opposite to that for the scanner. Accordingly, the present invention also proposes a reading book stand that is used by changing the direction of the book to be placed.

  The invention of claim 3 relates to a structure in which the right and left direction of the rectangular plate-like book cradle extended in the left-right direction can be expanded and contracted. The main book cradle is slidable to the left and right by being pressed by the spring force of the guide surface and the elastic member provided on the top or bottom edge of the main book cradle and the elastic member or the spring force of the main book cradle. There is a pair of left and right rectangular plate-shaped auxiliary book holders that can hold most of them on the back side of the book. It can be extended to handle large edition books. A claw-shaped stopper is provided at the inner end of the auxiliary book cradle to limit the left and right outward movement positions to prevent falling off. It serves as a stopper for limiting the position, and constitutes the outer edge of the receiving surface of the book cradle.

  A technique for pulling out and holding a general plate-like member as described above is well known, but by applying this technique, the book stand according to the claims can cope with a wide range of book sizes and can be stored. In addition to the effect of reducing the width of the left and right sides and shortening the sliding plate described in [0025], the effect of making the writing table small is great.

  According to a fourth aspect of the present invention, the USB stand scanner and the USB stand scanner reading stand according to the second aspect, or the scanner can be installed at an appropriate position outside the top side and the spread is as flat as possible. The present invention relates to a first embodiment for arranging a book stand having an arbitrary configuration that is constrained by the position in an optimal position and photographing a book spread held on the book stand. Further, the book stand of this claim is erected in the vicinity of the top and bottom ends of the book cradle and facing downward from the book cradle, and its lower end extends to the left and right parallel to the surface of the book cradle. It is effective for a book stand having a top and a ground leg on a pair of flat plates.

  The arrangement table has a rectangular plate-shaped base, and the upper surface of the base is divided into two parts in the longitudinal direction, and is fixed by extending in the lateral direction on the divided rear surface. And the upper side is open, and the writing stand described in [0032] is such that its top side is directed toward the front of the divided base [0032]. The lower end of either the top or the ground leg described in the above is inserted into the concave groove of the concave groove body, and is pressed against the side plate of the elastic body of the concave groove body so as to be slidable left and right. . Further, the book stand is fixed to the lower part of the leg that is not inserted into the concave groove body, or the concave groove body is fixed to the upper part, and the book holder is supported by a frame that is fixed to the left and right on the base. Is held so that its upper surface is parallel to the upper surface of the base.

  On the other hand, a vertically long trapezoidal body extending in the top direction on the divided front surface of the base is close to the top end of the center of the book stand arranged as described above. It is fixed. In the upper part of the trapezoidal body, the shape of the leg part according to the model of the USB stand scanner or the positioning by the left and right width thereof is used, and the column of the USB stand scanner can be installed perpendicularly to the base surface. There is a stage. In the USB stand scanner, the reading sensor is directed toward the reading table, the leg is fixed on the stage, and the stage is mounted along the guide wall provided on the table-like body or on the stage. Then, the stage is moved and arranged at an optimum top-and-bottom direction position for photographing the spread of the book placed on the reading table. Note that the scanner may be placed with the upper surface of the trapezoidal body directly as the stage surface, and moved on the stage surface in the vertical direction. Further, the optimum photographing position in the left-right direction of the spread surface is adjusted by moving the book stand to the left and right along the concave groove body.

  The optimum height of the stage surface from the base surface is about the position of the upper surface of the book cradle. The vertical length of the trapezoidal body or the stage is such that the USB stand scanner can be installed at a position corresponding to the largest book.

  The invention of claim 5 relates to the arrangement table of the second embodiment for optimally arranging the USB stand scanner and the reading table described in [0032]. The present invention provides the arrangement stand according to claim 4, wherein the installation position of the USB stand scanner on the stage in the vertical direction is fixed, the writing table is arranged on the auxiliary base, and the auxiliary base is arranged in the vertical direction. It is arranged on the base so as to be movable.

  5. A rectangular plate-shaped auxiliary base is placed on the rear surface of the base, which is divided into the front and rear surfaces of the vertically long rectangular plate similar to claim 4, with the vertical direction of the base being aligned with the vertical direction of the base. Then, it is held slidable in the vertical direction by the pressure applied by the guide surface and the elastic body provided on the left and right edges of the base in contact with the left and right ends. The concave groove body and the pedestal are provided on the auxiliary base by the same configuration as that arranged on the rear surface according to claim 4, and the USB stand scanner reading table is arranged on the auxiliary base. . A stage and a stage on which the USB stand scanner is placed are provided on the front surface of the divided base surface by the same configuration as described in claim 4. However, since the scanner is fixed on the stage and is not moved in the vertical direction, the trapezoidal body and the stage need not be vertically long in the vertical direction. The upper surface of the trapezoidal body may be directly used as a stage surface.

  Adjustment of the appropriate position of the writing table and the scanner in the vertical direction is performed by sliding the auxiliary base on the base surface. As in the case of claim 4, the adjustment of the position in the left-right direction is performed by sliding the leg portion of the book stand to the left and right along the concave groove body.

  Regarding which of the arrangement tables according to claims 4 and 5 is selected, the arrangement table according to claim 4 is for a normal size USB stand scanner, and the arrangement according to claim 5 is for a large size model. A stand is recommended.

1) New book reading with improved anti-turning support as described in claims 1 and 2 in a book stand that constrains the top of a book that turns pages naturally and the edge of the ground side The table solves the problem of changes in restraining force caused by insufficient conventional restraint height and large frictional force for each page turning, and the required restraint height and constant restraint height for each page turning are stable. Thus, turning over by the turning-up support is not an obstacle to page turning as in the prior art, and the page turning of the book stand is easy and quick.
2) The width of the left and right sides of the book cradle was reduced during storage by putting in and out the auxiliary book cradle, and the book stand was made compact.
3) Read the book stand according to claim 2 to cope with the inconvenience of holding a book spread that turns the page when you release your hand and taking a picture of a personal computer with a USB stand scanner. The case where it is placed with the top and bottom of the spread facing upside down, can be taken together with the USB stand scanner on the placement table according to claim 4 or 5, and the spread is held by hand. The following effects were obtained.
(1) Characters on the shooting screen are less distorted and lighter and darker, making it easier to see.
(2) The variation of the image screen and the position of the facing surface for each page turning has decreased.
(3) It is now possible to manually operate the switches during shooting.
(4) When viewing the shooting screen directly, the computer can be operated by hand.

  FIG. 1 is a perspective view in which the writing table 2 according to claims 2 and 3 is arranged on the arrangement table 1 of the first embodiment according to claim 4. There is a recessed groove body 4 that is fixed to the surface of the base 3 so as to cross the vertical end of the rectangular vertically long base 3 of the arrangement base 1, and the writing stand 2 is on the ground side below.

The columnar plate 15 is rotated to a position facing the columnar plate 15 and is held by the columnar plate 15 by the attractive force of the magnet 18 fixed to any surface facing the body. Ground-side turn-stops 21a and 21b are fixed to both wings of a ground-side turn-stop support plate 20 that is in contact with the back surface of the ground-side mounting plate 17 and is held by a screw 19 so as to be movable up and down. Corresponding to the length of the book in the vertical direction, the ground side turn-stops 21a, 21b are slid in the vertical direction to positions that restrain the ground side edge of the spread, and are held on the bottom surface of the groove 13.

  A base stand 22 is fixed to the base 3 and a USB stand scanner (not shown) is arranged on the stage 23 on the upper surface thereof, and its reading sensor is arranged in the direction of the book stand 2, and a screen image of the spread surface not shown is shown. It is installed along the upper surface of the stage 23 at the optimum position in the top-and-bottom direction or together with the stage 23 so as to be moved in the top-and-bottom direction. The book stand 2 held on the base 3 by the concave groove body 4 is slid along the concave groove body 4 and positioned at the optimal position in the left-right direction of the spread screen to be photographed.

Next, the setup and procedure for photographing the spread are described in numerical order.
(1) The ground-side mounting plate 17 together with the ground-side turn-stop support plate 20 is rotated backward to a position where the stopper 24 is effective.
{Circle around (2)} The top side edge of the spread spread to be photographed is inserted into the lower part of the top side turning stoppers 11a and 11b, and the top end is abutted against the surface of the contact plate 9.
(3) The ground side mounting plate 17 is rotated upward together with the ground side turn-stop support plate 20 while holding the spread surface with one hand, and is held on the columnar plate 15 by the magnet 18.
(4) The position of the sliding plate 14 is corrected in the vertical direction suitable for restraining the ground side edge portion of the double spread by the ground side turning stoppers 21a and 21b.
(5) Top and bottom positions where the top and bottom side turning stops 11a, 11b, 21a, and 21b are spread apart, and the height of restraining the edge of the ground is such that the spread is not excessively deformed and appropriate flatness is obtained. Adjust to.
(6) A USB stand scanner (not shown) is placed at an optimum vertical position on the stage 23 as described in [0034] while viewing the captured image, and the book stand 2 is placed along the groove 4. Hold at the right and left optimum positions.
(7) Shoot the facing surface and save the image on a personal computer, and move to page turning for shooting the next page.
(8) As for the page turning procedure, first, (1) is carried out so that the movement of the paper sheet to be turned by the ground side turn stoppers 21a and 21b is not hindered. Next, pull out from the lower part of the top-side turn stoppers 11a and 11b that hold the paper sheet to be turned, and insert the edge of the top side into the other lower part of the top-side turn stoppers 11a and 11b. 3) is carried out to constrain the ground side edge of the spread and the page turning is completed, and then photographing and storage are performed. For continuous shooting, step (8) may be repeated, but for thick books, step (5) is performed intermittently.

  2 is a book stand showing a first embodiment for constraining the top edge of the spread of the book 25 on which the top side turning stoppers 11a and 11b of the book stand 2 according to claims 2 and 3 are placed. 2 is a partial side view of the top side of FIG. The top-side turn-stop support plate 12 that has a vertically long hole 26 that is in contact with the back surface of the top-side mounting plate 10 fixed to the backing plate 9 and has the top-side turn-stops 11a and 11b fixed thereto passes through the hole 26. A screw 29 having a friction plate 27 and a disc spring 28 disposed on the back side of the head is screwed to the top mounting plate 10. The amount of pressure applied to the disc spring 28 is increased or decreased by the feed amount of the screw 29 to obtain an appropriate restraint height of the spread edge of the book 25 by the top-side turning stoppers 11a and 11b, and the restraining force is used to stop the top-side turning. The screw feed amount is set such that the upper end of the support plate 12 can be easily moved up and down by grasping with the finger. Thus, the subsequent adjustment of the vertical position of the top turning stoppers 11 a and 11 b can be carried out by grasping the upper end of the top turning stopper support plate 12 as described above, regardless of the looseness of the screws 29. When the level of the binding force differs depending on the book to be placed, the screw 29 may be tightened or loosened each time.

  FIG. 3 shows a second example in which the top side turning stoppers 11a and 11b of the book stand according to claim 2 restrain the top side edge of a book spread (not shown) placed on the book stand 2. It is an expansion | deployment perspective view of the top part of the book-reading stand 2 which shows an Example. The top-side turn-stop support plate 30 is pressed by the elastic bodies 32a and 32b that bypass the back side of the top-side mounting plate 31 fixed to the backing plate 9 and fit in the direction of the arrow ⇒ and is attached to the top side by the friction force. The top edge of the book spread is adjusted to an appropriate height and restrained by the top side turning stoppers 11a and 11b held by the plate 31 so as to be movable up and down. In this configuration, since the frictional force cannot be adjusted by the book on which it is placed, the frictional force needs to be increased.

  FIG. 4 is a ground side partial side view in which the anti-turning support 33a of the first embodiment according to claim 1 is applied to the ground side of the book stand 2 according to claims 2 and 3. A screw 36 penetrating a vertically long hole 35 provided in the bottom 34 of the concave groove 13 (see FIG. 1) of the reading table 2 causes the sliding plate 14 to be attached to the bottom 34 via a friction plate 37 and a disc spring 38. Screw on top. Positioning of the sliding plate 14 in the vertical direction is carried out by slidably holding the disc plate 38 with an appropriate pressure by tightening or loosening the screw 36.

  The columnar plate 15 according to claim 1 is added upward to the ground side end of the sliding plate 14 to form an L-shaped member together with the sliding plate 14, and the ground side mounting plate 17 is rotated by a hinge 16 at the lower end thereof. The columnar plate 15 and the ground-side mounting plate 17 face each other by rotation, and the ground-side mounting plate 17 is locked to the columnar plate 15 by the attractive force of the permanent magnet 18 fixed to one of the surfaces. The part of the ground side mounting plate 17 and the columnar plate 15 facing the permanent magnet 18 must be made of a material having magnetic attraction such as an iron plate. The permanent magnet 18 has a large coercive force such as a rare earth magnet. It is desirable to have a small size and a large adsorption power.
