Sliding mechanisms using slide spaces and guide rails, sliding mechanisms using racks and pinions, and slide structures supported on the backing plate, guide plates with guide holes for guiding the slide structures, and special structures of sliding using leaf springs. Mechanisms and the like are known. Furthermore, U. S. Patent No. 6,073, 027 proposes a sliding mechanism for opening and closing a cover by slidably connecting a cover having a latch, a latch catch and an actuator to a housing using a tension spring.

The sliding mechanism has a disadvantage in that the operation feeling of the slide member is inferior.

In addition, the slide method of the prior art has a disadvantage that the distance that the slide cover is moved in one operation.

In addition, there is a conventional one to move the slide using the elastic force of the spring, but the frictional force between the members and the frictional force between the members such as the friction force between the slide member and the guide member, the friction force between the slide member and the guide bar in the vicinity of the moving distance There is also a problem that a stop section or a stop point is generated in which the slide stops due to the balance of forces.

And when the elastic force of the spring for pushing the slide member is falling there is a concern that the slide member can be shaken in a stable position at the highest position and the lowest position.

In some cases, the magnetic material may be provided in plural intervals, and may be configured to repeatedly change the magnitude of the magnetic force interacting with the first magnet while the slide member moves through the entire section.

When the slide member is at the top position or the bottom position of the guide member, the first magnet and the magnetic body are relative to interact with the magnetic force to push the slide upward in the top position or downward in the bottom position. Each location can have its own configuration.

In some cases, when the slide member is at the highest position or the lowest position of the guide member, the first magnet and the magnetic body interact with each other to attract magnetic forces such that the slide stops at the highest position or at the lowest position. It may also have configurations installed in relative positions, respectively.

Sliding opening and closing device 100 according to a first embodiment of the present invention is shown in FIG. The sliding opening and closing device 100 includes a slide member 110 and a guide member 140.

The guide member 140 extends along the first and second guide rails 144a and 144b having a predetermined width and height along both parallel parallel edges of the rectangular plate 142. The outer side surfaces of the first guide rail 144a and the second guide rail 144b are formed with long first and second guide rail grooves 146a and 146b in the longitudinal direction, respectively. The first magnets m1 are provided at intervals along the guide rails 144a and 144b of the guide member 140. The first magnets m1 may have holes formed in the guide member 140, and the first magnets m1 may be inserted into the holes and fixed or inserted into the holes. These first magnets (m1) is to improve the operating feeling between the slide member 110 and the guide member 140 by providing a force change in multiple stages when the slide member 110 moves. Of course, the first magnet (m1) is not to be installed on both of the guide rails (144a, 144b), may be installed on only one side, or may be installed along the left and right centers of the guide member 140. In addition, the magnet m1 may be installed along the inside of the guide rails 144a and 144b.

To apply attraction force to the corresponding portion of the magnet installed in the slide member 110 when the slide member 110 is in the uppermost position and the corresponding portion of the magnet installed in the slide member 110 when the slide member 110 is in the lowest position. When installing a magnet and a magnet or a magnet and a magnet that is not magnetized, it also serves to hold the slide member 110 does not move at the corresponding position. Then, according to the position of the magnet and the magnet or the non-magnetized magnet and the arrangement of the opposite poles, the pushing force is applied to the slide member in the uppermost position, and the sliding force is pushed downward in the lowest position. It is readily appreciated that it can be configured to act on the member.

In addition, when a magnet is provided in the slide member 110 described later, the magnetic member which is not magnetized may be provided in the guide member 140. FIG. As nonmagnetic magnets, it is preferable to use iron, cobalt, nickel or alloys thereof known as ferromagnetic materials. The back of the guide member 140 is formed with a plurality of coupling holes, for example, a screw thread formed with a coupling hole for fixing the upper body (not shown) of the mobile phone.

The slide member 110 is engaged to slide in a linear direction to the guide member 140. In the structure of the slide member 110 for this purpose, protruding first and second rails 114a and 114b are formed along opposite parallel edges of the rectangular plate 112, and the first rail ( 114a) and the second rail 114b are slidably engaged with the first guide rail groove 146a and the second guide rail groove 146b of the guide member 140, respectively. The second magnet m2 is provided near the upper end of the slide member 110. Two or more 2nd magnets m2 may be provided at intervals. The second magnet (m2) is to interact with the first magnet (m1) to move the slide member 110 on the guide member 140 in order to change the force in multiple stages to improve the feeling of operation. In this case, the first magnet m1 and the second magnet m2 may have the same poles or opposite poles. Of course, when the magnet is installed in the guide member 140, the slide member 110 may be provided with a non-magnetized magnetic material as described above instead of the magnet. A plurality of coupling holes 116a to 116d are formed on the rear surface of the slide member 110 to fix the lower body (not shown) of the mobile phone.

After assembling the sliding device 110 of FIG. 1, and screwing the upper body and the lower body of the mobile phone to the guide member 140 and the slide member 110, respectively, the slide type mobile phone (not shown) with excellent operating feeling Can be completed.

Figure 2a is an exploded perspective view showing a second embodiment employing a spring in Figure 1 sliding opening and closing device.

As shown in FIG. 2A, the sliding opening and closing device 100 according to the present invention includes a slide member 110, a first torsion spring 120, a second torsion spring 130, and a guide member 140. do.

In FIG. 2A, portions different from those of FIG. 1 are the first torsion springs 120 and the second torsion springs 130 and the components for installing them, and the rest are the same as those shown in FIG. 1. Here, only portions that differ from FIG. 1 will be described.

A V-shaped groove 149a is formed near the center point of the first guide rail 144a, and a coupling hole 148a is formed at the vertex of the groove 149a. Similarly, the V-shaped groove 149b and the coupling hole 148b are formed in the second guide rail 144b. However, the positions of the two coupling holes (148a, 148b) are separated from each other by a predetermined length at the position facing each other. Forming the V-shaped grooves 149a and 149b in front of the coupling holes 148a and 148b is a consideration for preventing the rotation of the first and second torsion springs 120 and 130.

Two coupling holes 118a and 118b are formed at two points of the central portion of the rectangular plate 112 of the slide member 110. The two coupling holes 118a and 118b are hermetically spaced apart from the center line CL by dividing the width of the slide member in half.

The first torsion spring 120 includes a first coil 122 wound in a substantially circular shape, and two arms 124a and 124b extending a predetermined length from both ends of the first coil 122. The ends of the two arms 124a and 124b are bent at approximately right angles. The first torsion spring 120 is disposed in a space formed between the slide member 110 and the guide member 140 engaged with each other. The end of one arm 124a of the first torsion spring 120 is pivotally inserted into the coupling hole 148a of the guide member 140, and the end of the other arm 124b is slide member 110. Is pivotally inserted into the coupling hole 118b.

The second torsion spring 130 is also substantially the same shape as the first torsion spring 120, and consists of two arms 134a and 134b extending a predetermined length around the second coil 132, and two arms 134a. 134b) is also bent. The end of one arm 134a of the second torsion spring 130 is pivotally inserted into the coupling hole 148b of the guide member 140, and the end of the other arm 134b is slide member 110. Is pivotally inserted into the coupling hole 118a.

It is preferable that the angle between the two arms 124a and 124b is as large as possible in the first torsion spring 120 without an external force applied thereto. The same applies to the second torsion spring 130. This is because the larger the angle between the two arms of the torsion spring, the longer the moving distance of the slide member 110 is.

FIG. 2B is a perspective view illustrating a modified example of FIG. 2A, and in some cases, the sliding opening and closing device may be configured by installing only one side of the first magnet m1 and the second magnet m2 on both sides. Of course.

FIG. 3 is a plan view of the sliding switch assembly of FIG. 2A, illustrating a state in which the slide member 110 is located near the center of the moving section.

Generally, when the slide member 110 is assembled to the guide member 140, the slide member 110 is pushed to one end of the guide member 140 by the elastic force of the first and second torsion springs 120 and 130. Keep it. In this state, when the slide member 110 is moved to the other side and reaches the center of the moving section, the first torsion spring 120 and the second torsion spring 130 are guide members 140 to the slide member 110. A force acting in the longitudinal direction of the slide member 110, ie, the moving direction of the slide member 110, maintains an equilibrium, resulting in a stop section or a stop point at which the slide member 110 stops near the center. The first magnet m1 is arranged such that the surface facing the second magnet m2 has the same pole near the position where the second magnet m2 installed on the slide member 110 reaches the stop section or the stop point. When the balance of the force between the first torsion spring 120 and the second torsion spring 130 is broken, the stop section or the stop point of the slide member 110 may be eliminated. Of course, when the first magnet (m1) and the second magnet (m2) is 100% parallel and facing at the correct position, in theory, since the slide member 110 can move the same force in both directions can move each other It can be seen that the slide member 110 does not have the effect of leaving the stop section or stop point, but in reality it is difficult to do so. However, in the process of designing the magnet arrangement, when the slide member 110 is at the stop section or the stop point, the first magnet m1 and the second magnet m2 are respectively positioned at relative positions where the largest repelling force can be applied to each other. It is desirable to install.

In addition, the surface facing the second magnet (m2) in the position as shown by the dotted line of Fig. 3 slightly out of the position reached by the second magnet (m2) installed in the slide member 110 in the stop section or stop point. The stop section or the stop point may be removed by arranging the first magnet m1 to have a pole different from the two magnets m2.

In addition, when a plurality of the first magnet (m1) or the second magnet (m2) or both are installed at intervals, the magnetic force acting between the magnets (m1, m2) that encounter each other when the slide member 110 slides. The operation feeling by the change of is provided.

The first and second torsion springs 120 and 130 are rotated to push the slide member 110 to the upper side or the lower side when the stop section or the stop point is moved, so that the slide member 110 can be automatically moved.

In the uppermost state or the lowest state of the slide member 110 on the basis of the state in which the sliding opening and closing device 100 is set on the left side of FIG. 3, the two torsion springs 120 and 130 have the elastic force of the slide member 110 upward. Or it pushes downward to bias, so it also functions as a latch.

It is particularly noteworthy that consideration for increasing the maximum moving distance L of the slide member 110 with respect to the width W of the guide member 140 is considered in the design of the slide apparatus 100. 2A, 2B, and 3, in order to increase the maximum moving distance L of the slide member 110, it is necessary to utilize the gap in the width direction of the guide member 140 as much as possible. As a method for enabling this, the present invention takes special consideration of the coupling position of the slide member 110 and the guide member 140 of the two torsion springs (120, 130). Specifically, when the end of one arm 124a of the first torsion spring 120 shown in FIG. 2 is located near the left edge of the guide member 140, the end of the other arm 124b is the slide member ( In the right half region of 110 (in FIG. 3, the region below the center line CL corresponds to this). Similarly, when the end of one arm 134a of the second torsion spring 130 coupled with the slide member 110 is positioned near the right edge of the guide member 140, the end of the other arm 134b is the slide member. Positioned in the left half region of 110.

Unlike the above method (hereinafter referred to as 'first method'), the arm 124b of the first torsion spring 120 coupled with the slide member 110 is located in the left half region of the slide member 110, and the slide member ( When the arm 134b of the second torsion spring 130 coupled to 110 is positioned within the right half region of the slide member 110 (hereinafter referred to as 'second method'), the maximum moving distance L of the slide member 110 ) Is significantly reduced compared to the above. This is because the space in the width (W) direction of the guide member 140 is not utilized to the maximum.

There is a correlation between the maximum moving distance L of the slide member 110 and the width W of the guide member 140. If the width W is narrowed, a constraint is placed on increasing the maximum travel distance L. According to the first method, the width W of the guide member 140 may be smaller than that according to the second method to obtain the same maximum moving distance L. FIG. The first method is because the two torsion springs 120 and 130 make maximum use of the width (W) direction spacing when the compression-extension while rotating.

Mobile phones are required to be designed with short and thin structures. The first method is more advantageous in order to reduce the width W of the slide member 110 and the guide member 140 while obtaining the required maximum moving distance L. Thus, in mobile phone design, it means that the first scheme can better accommodate short and thin design requirements than the second scheme.

With this structure, the upper and lower bearings 327a, 327a ', 327b, 327b' and the upper and lower buffer rubbers 352a, 352a ', 352b, and 352b do not directly contact the guide member 310 and the slide member 320. ′) Contacts each other to mitigate impact and reduce noise.

The first and second slide coupling hands 324a and 324b are also provided with first and second rails 328a and 328b which face inwardly and protrude, and are provided with the first rail 328a and the second rail ( 328b is slidably engaged with the first guide jaw 318a and the second guide jaw 318b of the guide member 310, respectively. At this time, there is a slight gap between the first and second rails 328a and 328b and the first and second guide jaws 318a and 318b engaged therewith, and thus do not contact each other when sliding. During the slide, the first and second guide bars 350a and 350b and the first and second guide holes 326a and 326b dominantly interact with each other to move, and the first and second guide jaws 318a and 318b. The first and second rails 328a and 328b auxiliaryly suppress distortion or deviation in other directions in the horizontal motion, thereby allowing the slide member 320 to be stably driven in the guide member 310.

In addition, two coupling holes 329a and 329b at which two ends of the first and second torsion springs 330 and 340 are fixed are formed at two points of the central portion of the rectangular substrate portion 322 of the slide member 320. . The two coupling holes 329a and 329b are hermetically spaced apart from the center line CL by dividing the width of the slide member 320 in half. Slide member 120 is also formed with a plurality of coupling holes (320a ~ 320d) for fixing to the lower body (not shown) of the mobile phone.

The first torsion spring 330 includes a first coil 334 wound in a substantially circular shape, and two arms 332a and 332b extending a predetermined length from both ends of the first coil 334. The ends of both arms 332a and 332b are bent at approximately right angles. The first torsion spring 330 is disposed in the interspace formed by the slide member 320 and the guide member 310 engaged with each other. The end of one arm 332a of the first torsion spring 330 is pivotally inserted into the coupling hole 312a of the guide member 310, and the end of the other arm 332b is slide member 320. Is pivotally inserted into the coupling hole 329a.

The second torsion spring 340 is also substantially the same shape as the first torsion spring 330, and consists of two arms 342a and 342b extending a predetermined length with the second coil 344 as the center, and the two arms 342a. 342b) is also bent. One end of one arm 342a of the second torsion spring 340 is rotatably inserted into the coupling hole 312b of the guide member 310, and the other end of the arm 342b is slide member 320. Is pivotally inserted into the coupling hole 329b.

The first torsion spring 330 is preferably an angle between the two arms (332a, 332b) is as large as possible when no external force is applied. The same applies to the second torsion spring 340. This is because the larger the angle between the two arms of the torsion spring, the longer the moving distance of the slide member 320 is.

Magnets m2 are provided near the lower edges of the slide 320. The magnet m2 may be pressed into the hole h formed in the slide 320 to be fixed or installed by insert injection. This magnet (m2) interacts with the ferromagnetic material (m3) installed in the guide member 310 to maintain the position more stably in the top position and the lowest position corresponding to the cover of the mobile phone, such as fully open or fully closed On the other hand, and the interaction with the ferromagnetic material (m3) installed in the guide member 310 in the vicinity of the center of the moving section serves to prevent the stop section or stop point occurs. The magnet (m2) can be installed by changing the position and the ferromagnetic material (m3) installed in the guide member 310, it is more preferable to install a magnet on both the guide member 310 and the slide (320). .

After assembling the sliding opening and closing device 300, by screwing the upper body and the lower body of the mobile phone to the guide member 310 and the slide member 320, respectively, the slide-type mobile phone (not shown) is completed.

In this case, it is possible to obtain a slide opening and closing device in which the stop section or the stop point of the slide member 320 is removed. In the case where the magnet and the magnetic body are installed more spaced apart from the slide member 320 and the guide member 310, the operation feeling may be improved due to the change of the magnetic force acting between the magnet and the magnet or the magnet and the magnetic body during movement. .

Although it is optimal to fix the guide member and the slide member to each side of the mobile phone as above, the slide member and the guide member are mutually movable, and even if the guide member is attached to the lower body and the slide member is attached to the upper body, the operation is prevented. Does not cause

7A is an exploded perspective view showing an application device to which the sliding opening and closing apparatus is applied according to the fourth embodiment of the present invention, FIG. 7B is an exploded perspective view showing a modified example thereof, and FIG. 8 is a front view of the application device of FIG. 7A assembled. 9 is an assembled cross-sectional view taken along the line GG of FIG. 8. In this embodiment, a sliding mobile phone is exemplified as an application device, and the sliding mechanism integrated into the sliding mobile phone shows a guide bar-type sliding mechanism.

As mentioned above, the mobile phone is composed of a main body 2100 and a cover 2200 mounted above the main body 2100 and sliding sliding on the main body 2100. Thus, in order for the lid 2200 to slide and slide on the main body 2100, the sliding mechanism is comprised in the facing part of the lid 2200 and the main body 2100. As shown in FIG. That is, in the present embodiment, the guide rail structure is formed on the rear surface of the cover 2200, and the slide structure sliding on the guide rail structure is provided on the upper side of the front surface of the main body 2100 facing the rear surface of the cover 2200. Doing. The guide rail structure of the cover 2200 is formed of the most of its components integrally on the back cover 2200, the slide structure of the main body 2100 is composed of a separate plate is mounted on the front of the main body 2100 .

Specifically, as illustrated, a slide space 2210 is provided on the rear surface of the lid 2200 in which the slide structure of the main body 2100 is movably received in the sliding direction. The slide space 2210 recessed on the back surface of the cover 2200 is formed in consideration of the slide distance in the slide direction, and a pair of left and right guide bars 2220a and 2220b are adjacent to the left and right side walls in the slide space 2210. It is installed. In fixing both ends of the guide bars (2220a, 2220b) to the cover 2200, one end of the guide bars (2220a, 2220b) is in communication with the slide space 2210, the fixing groove formed on the upper side of the back cover 2200 The second ends of the guide bars 2220a and 2220b to the fixing grooves 2232a and 2232b formed in the gripping piece 2230, and then the gripping piece 2230 is disposed on the back of the cover 2200. It is in close contact with the lower end of the slide space 2210 of the coupling through the coupling means such as bolts (2240). At this time, the rubber packing (2222a, 2222b, 2224a, 2224b) to the both ends of the guide bars (2220a, 2220b) to be inserted into the fixing grooves (2212a, 2212b, 2232a, 2232b) or fixed, or guide bars (2220a, 2220b) Both ends of the 2220b are directly fixed to the fixing grooves 2212a, 2212b, 2232a, and 2232b. The former case is preferable because it is advantageous to compensate for assembly errors or to provide a cushioning force during sliding slide. Of course, the guide rails described above may be formed at the lower ends of the slide space 2210 and the fixing grooves 2212a and 2212b formed directly on the rear surface of the cover 2200 and the grip pieces 2230 are fixed to the upper ends of the slide space 2210. There is no reason to perform the same operations and functions as the structure.

In addition, the cover 2200 is formed by the guide bar support groove (2221) so that the lower side of the guide bar (2220a, 2220b) can be inserted and supported so that the guide bar (2220a, 2220b) is not deformed, and the application of The thickness can be reduced.

The first magnets m1 are disposed up and down at intervals in both guide bars 2220a and 2220b. These first magnets m1 are installed on the movement path of the second magnet m2 installed in the slide member 2110 and sequentially with the magnet m2 installed in the slide member 2110 when the slide member 2110 moves. It is to make the operator feel the operation.

A sliding structure that slides in the guide rail structure is provided on the front surface of the main body 2100 corresponding to the sliding space 2210 on the rear surface of the cover 2200. This sliding structure is made of a slide member 2110 separate from the main body 2100 and fastened to the front of the main body 2100 by bolts 2102 and fixed. The slide member 2110 includes a pair of left and right coupling hands 2120a and 2120b in a sliding direction, and guide holes 2122a and 2122b having one side opened in the left and right pair of coupling hands 2120a and 2120b. ) Is formed in the sliding direction and fitted to the left and right guide bars 2220a and 2220b mounted on the rear surface of the cover 2200, respectively. As shown in FIG. 7, when one side of the guide holes 2122a and 2122b is opened to partially accommodate the guide bars 2220a and 2220b, the thickness of the slide member 2110 may be reduced, resulting in a slide. The thickness of the switchgear or application device can be reduced. On the other hand, the sliding structure having the above configuration may be molded integrally with the body 2100, which will be described later.

As shown, the slide member 2110 is provided with a plurality of second magnets m2 spaced up and down in both guide holes 2122a and 2122b. These second magnets (m2) interact with the magnets (m1) installed in the cover 2200 so that when the operator opens or closes the cover 220, the change of force can be felt in multiple stages in the operator's hand sequentially give. When the plurality of magnets m2 are arranged vertically in the slide member 2110 as described above, the operator operates larger because the total magnetic force interacting with the magnets m1 installed on the cover 2220 corresponding to the guide member increases. I can feel it. Here, the magnets m1 and m2 disposed to face the slide member 2110 and the cover 2200 may be configured to have opposite poles with the same poles or different poles, Therefore, the poles of the magnets m1 and m2 installed adjacent to each other in the slide member 2110 and the cover 2200 may be alternately arranged.

In addition, the present invention is added to the rail guide structure in addition to the guide bar guide structure described above. In detail, the guide rails 2214a to 2214f protrude toward the slide space 2210 on the left and right side walls where the slide space 2210 ends on the rear surface of the cover 2200. Correspondingly, the guide jaws 2124a and 2124b engaged with the guide rails 2214a to 2214f are formed on the outer surfaces of the engaging hands 2120a and 2120b of the main body 2100 that are accommodated as the slide space of the cover 2200. Is formed. As illustrated in FIG. 7, the guide rails 2214a to 2214f are configured by dividing the guide rails 2214a to 214a into an upper side, a middle portion, and a lower side along the sliding direction in the sliding space 2210a. In particular, the interval between the guide rails 2214a to 2214f is to be fitted into the slide space 2210 from the front in accordance with the divided upper and lower intervals of the guide jaw (2124a, 2124b) engaging with it. When the guide rails 2214a to 2214f are formed on the upper and lower sides and the middle portion of the slide space 2210, the binding force of the main body 2100 and the cover 2200 is doubled at the upper and lower positions, which are the stop positions, thereby making the binding force stronger in use. To provide. In other words, the upper guide rails 2214a and 2214b are lowered when the cover 2200 is in the lowermost position, that is, when the cover 2200 is overlapped with the main body 2100 to close the coupling hands 2120a and 2120b. Engaging with the guide jaws 2124a and 2124b, the binding force between the main body 2100 and the cover 2200 is strengthened and is not easily separated by external impact, and when the cover 2200 is at the top, that is, the cover 2200 is opened. When opened by sliding upward from the main body 2100, the lower guide rails 2214e and 2214f are raised to engage with the guide jaws 2124a and 2124b of the engaging hands 2120a and 2120b, so that the main body 2100 and the lid ( The binding force of 2200 is strengthened. In the mobile phone, since the cover 2200 is normally present at the top and bottom of the normal use, the guide rails 2214a to 2214f may be configured only in these two places to strengthen the binding force at the time of use. In addition, a plurality of guide rails may be configured at equal intervals along the slide direction, or may be continuously extended and protruded along the slide direction in both the left and right sections. As described above, in addition to the slide guide structure by the guide bar, it is advantageous to use the rail structure in combination to ensure the straightness during the sliding slide.

Although the aforementioned sliding space 2210 is formed as one space that can accommodate a pair of coupling hands 2120a and 2120b together in the present embodiment, coupling hands 2120a and 2120b may be respectively accommodated. It may be divided into two linear grooves along the sliding direction. Further, the guide rails 2214a to 2214f and the guide jaws 2124a and 2124b protrude guide guides into the coupling hands 2120a and 2120b and the inside of the coupling hands 2120a and 2120b in the slide space 2210. It can also be configured to engage the protruding guide rail to the corresponding portion.

In some cases, as shown in FIG. 7B, the magnets m1 and m2 may be installed on only one side of both sides to configure an application device according to the present invention. The rest is the same as described earlier.

10A and 10B are exploded perspective views showing another embodiment of the present invention to which a guide bar-type sliding mechanism is applied, and FIG. 11 is a view schematically illustrating the sliding mechanism when viewed from the front in an assembled state of the application device of FIG. 10A.

In the guide bar-type sliding mechanism illustrated in the drawings, the guide bar guide structure is the same as the structure and coupling relationship between the guide bar and the guide hole described above with reference to FIGS. 7A to 9, and thus a detailed description thereof will be omitted.

The mobile phone can be configured by integrally molding the upper surface of the main body 2100a instead of a separate slide member as in the previous embodiment in order to improve the assembly and simpler as in this embodiment. As a result of the integral molding, the pair of coupling hands 2120c and 2120d protrude from both sides of the upper surface of the front surface of the main body 2100a. The structure and shape thereof are the same as in the previous embodiment.

In this embodiment, only the guide bar guide structure consisting of the guide bar (2220c, 2220d) and the guide bar (2220c, 2122d) with the guide bar (2220c, 2220d) is removed, it is possible to ensure accurate sliding operation. Therefore, even if the rail guide structure consisting of the guide rails (2214g ~ 2214l) and the guide jaw (2124c, 2124d) is removed, the operation is not hindered, and if the rail guide structure is added, more precise and stable operation can be guaranteed. This can make manufacturing molds a little complicated and difficult to assemble.

The remaining arrangements of the magnets m1 and m2 respectively installed on the corresponding opposing surfaces of the main body 2100a and the cover 2200a are similar to those of the previous embodiment. However, in the previous embodiment, while the second magnet m2 is installed in the slide member, in this embodiment, the second magnet m2 is different from the point in which the second magnet m2 is directly installed in the main body 2100a. Is the same as

Broadly speaking, the main body 2110a can be viewed as a slide member and the lid 2200a as a guide member.

As shown in FIG. 10B, in some cases, the magnets m1 and m2 may be installed only on one side of the slide member and the guide member to configure the application device according to the present invention.

It is pivotally inserted into and fixed to the other end, and the other end of the arm 2330a is pivotally inserted into the coupling hole 2130a formed at approximately the center position of the left and right coupling hands 2120e and 2120f of the main body 2100b. .

The shape of the second torsion spring 2300b is also the same as that of the first torsion spring 2300a, and only the fixed positions at both ends thereof are different, and the two arms 2320b and 2330b extending a predetermined length with the second coil 2310b as the center. The ends of both arms 2320b and 2330b are also bent. One end of the arm 2320b of the second torsion spring 2300b is pivotally inserted into the coupling hole 2216b formed at the right middle height of the slide space 2210b, and the other end of the arm 2330b is pivotally inserted. It is pivotally inserted into a coupling hole 2130b formed at approximately a center position of the left and right coupling hands 2120e and 2120f of the main body 2100b.

It is preferable that the angle between the two arms 2320a and 2330a is as large as possible in the first torsion spring 2300a without an external force applied thereto. The same applies to the second torsion spring 2300b. The larger the angle between the two arms of the torsion spring, the longer the moving distance of the slide structure.

Since the structure and operation principle of the first and second torsion springs 2300a and 2300b have been described in detail above, detailed description thereof will be omitted here.

In addition, although the distance and the number of the magnets m1 and m2 installed in the main body 2100b and the cover 2200b are different from those in the previous embodiment, the operation principle is as described above.

Of course, it can be easily seen that the first and second torsion springs can be further configured as shown in FIG. 12 in the application device shown in FIGS. 10A and 10B.
