Description

High-speed punching machine linkage type roll-to-roll material exposure system and application method thereof
Technical Field
The present invention relates to a high-speed press-linked roll-to-roll material exposure system and an application method thereof, and more particularly, to a high-speed press-linked roll-to-roll material exposure system and an application method thereof, which can repeatedly form a fine circuit pattern on a continuous roll-shaped flexible circuit board in a very precise manner without an error in conjunction with a high-speed press that removes an unnecessary portion of the flexible circuit board used as a mobile phone part, and rapidly and accurately perform exposure in a state of a very low energy consumption rate, thereby easily realizing mass production without causing a defect.
Background
Recently, various electronic devices including mobile communication handsets (portable terminals) are becoming smaller and lighter.
Generally, a mobile phone has a small internal area (capacity), and all components used therein are small and light, and a Printed Circuit Board (PCB) on which various electronic components necessary for the mobile phone are mounted is mainly a flexible printed circuit board which can be freely bent in such a manner that the mounting can be easily performed on a small internal area, and various signals and electric power can be smoothly flowed. On the other hand, in the following description, the flexible circuit board may include materials that are thin and perform a specific function, such as a Touch Screen Panel (Touch Screen Panel), a backlight Unit (BLU), a Gasket (Gasket), a cosmetic mask, a medical tape, and the like.
Also, an antenna (antenna), which is a necessary electronic component in a wireless device, is also manufactured in a pattern forming manner on a flexible printed circuit board, and is manufactured by removing unnecessary portions by a punching (stamping) manner, and the flexible printed circuit board is configured by a roll-to-roll material according to an increase in demand, so that mass production can be realized, and a high-speed punching machine can be used when removing unnecessary portions other than necessary patterns.
On the other hand, the pattern to be formed on the roll-to-roll material is predetermined by design and manufactured precisely, and it is a very common process manner to perform a punching process for removing unnecessary portions in advance.
However, in the punching step, foreign matter is generated in the roll-to-roll material, and when such foreign matter is applied to an exposure step for forming a pattern on a photosensitive film, there is a problem that the defective rate of the pattern which needs to be miniaturized and produced with precision is increased.
A prior art partially solving such a problem is "foreign matter screening apparatus for punching material of high speed punching machine" of korean patent No. 10-1968473 (2019, 04/07).
Fig. 1 is a main configuration diagram illustrating a punching material foreign matter screening apparatus of a high-speed punching machine according to an embodiment of the related art.
Hereinafter, the body 310 is provided with a caster 312 at a lower end thereof, the roll-to-roll material fed in a state where punching is completed by the material feeding unit 320 is horizontally moved by the first roller unit 314 and the second roller unit 316, the thickness sensor unit 332 constituting the foreign matter screening device unit 330 measures the thickness of the material and notifies the controller 340 of the measured thickness, and the controller 340 controls the cylinder 334 to mark "NG" as a material mark including foreign matter.
The conventional art has an advantage that it is possible to determine whether or not the inflow foreign matter is attached to the roll-to-roll material, but has a problem that it is impossible to screen and remove only the confirmed foreign matter.
On the other hand, in the conventional flexible printed circuit board production system, since the raw material is hard (hard), when a pattern is formed on a curved surface, problems such as easy separation and detachment of the pattern occur, thereby consuming much production cost.
In addition, in the conventional Metal Foil Antenna (MFA) system, since a pattern is formed using an extrusion die, it is difficult to embody a fine pattern, a large amount of die cost is required, and it is difficult to deform the pattern, thereby consuming a large amount of initial development cost.
In addition, in the Laser Marking Antenna (LMA), when impact is applied due to lowering of a product by plating gold after laser marking, a crack is generated in an injection-molded product and a pattern is broken.
Therefore, it is necessary to develop a technology for removing foreign matters included in a roll-to-roll material and precisely transferring the roll-to-roll material, reducing production costs while precisely performing exposure for pattern printing on the roll-to-roll material, preventing a pattern separation phenomenon from occurring on a curved surface of the material, easily forming a fine pattern, easily deforming the pattern, and preventing the pattern from being broken even if an impact is applied due to a drop or the like.

That is, the second foreign matter removal portion 4000 is a method of removing foreign matters for the second time (second stage) by rotating the roll-to-roll 950 transferred between the two rubber rollers and removing the foreign matters by adsorbing the foreign matters attached to the upper and lower surfaces of the roll-to-roll 950.
The third foreign substance removal portion 4500 has the same structure and the same function as those of the second foreign substance removal portion 4000, and therefore, the description will not be repeated below, but a description will be made by distinguishing characteristic operations.
The third foreign substance removal portion 4500 removes foreign substances by adsorbing the foreign substances attached to the upper surface and the lower surface of the roll-to-roll material 950 by rotation, and thus belongs to a manner in which the foreign substances are removed for the third time (third stage).

As shown in fig. 3, the first pin hole guide roller 5000 is such that a plurality of roller guide pins 5010 protruding outward in the radial direction are arranged at the same interval a, and in each roller guide pin 5010, the interval a on the front end portion protruding with the corresponding central axis as a reference is 9.5mm, and is arranged and disposed in such a manner that the error is maintained at 0.05mm, and the front end portion of each roller guide pin 5010 has an oval cross section in such a manner that it can be easily inserted into and easily separated from the roller guide hole 960 of the roll-to-roll material 950.
Each roll guide hole 960 of the 13 th roll-to-roll material 950 is designated as a wrist pin guide hole 970.
The second pin hole guide roller 5500 has the same structure and the same function as the first pin hole guide roller 5000, and therefore, the following description will not be repeated, but a description will be given while distinguishing characteristic operations.
The first roller tension unit 6000 is sequentially provided at the lower end of the first pin hole guide roller 5000, and measures and adjusts the transfer speed of the roll-to-roll material 950 transferred between the vertically arranged rollers according to the control signal.
The first roller tension part 6000 includes an upper press roller 6010, a lower rotating roller 6020, a roller pressing cylinder 6030, a transfer servo motor 6040, a roller pressing pressure detection sensor 6050, and a material transfer speed detection sensor 6060.
The upper press roller 6010 and the lower rotation roller 6020 have cylindrical shapes as a whole with their respective rotation center axes positioned vertically along the vertical direction, and the outer peripheral surfaces of the cylindrical shapes are in close contact with each other and rotate in opposite directions by friction, and the outer peripheral portions of the respective cylindrical shapes are formed of a rubber material.
The roller pressing cylinder 6030 is configured such that a piston rod that extends or contracts in response to a control signal from the roll-to-roll exposure control unit 8000 is connected to a rotation center axis of the upper pressing roller 6010. The roller pressure cylinder 6030 moves the upper pressing roller 6010 downward in response to a control signal from the roll-to-roll exposure control unit 8000 to adjust the pressing strength to be high, or moves the upper pressing roller 6010 upward to adjust the pressing strength to be low.
The transfer servo motor 6040 is connected to the rotation center axis of the lower rotating roller 6020 by a shaft, rotates the lower rotating roller 6020 in response to a control signal from the roll-to-roll exposure control unit 8000, and is configured by a servo motor whose rotation speed is adjusted in response to the control signal.
Preferably, the transfer servo motor 6040 is controlled to rotate at 250RPM as a reference.
The roll pressure detection sensor 6050 is in contact with the rotation center axis of the upper pressing roller 6010, and notifies the roll-to-roll exposure control unit 8000 of the detection of the strength of the downward pressing force of the upper pressing roller 6010.
The material transfer speed detection sensor 6060 detects the roll guide hole 960 of the roll-to-roll material 950 based on a control signal corresponding to the connected roll-to-roll exposure control unit 8000, thereby detecting the transfer speed of the roll-to-roll material 950. Preferably, the material transfer speed detection sensor 6060 outputs an optical signal and detects the transfer speed of the roll-to-roll material 950 by receiving the optical signal reflected by the transfer table 2000. However, it is needless to say that the transfer speed of the roll-to-roll material 950 may be detected by another method as necessary.
The second roll tension portion 6500 has the same structure and the same function as the first roll tension portion 6000, and therefore, the following description will not be repeated, but a description will be given with a distinction in characteristic operation.
The transfer servo motor 6040 constituting the first roller tension part 6000 and the transfer servo motor 6040 constituting the second roller tension part 6500 may have different rotation speeds according to the corresponding control signal of the roll-to-roll exposure control part 8000, respectively.
As an example, the transfer servo motor 6040 constituting the second roller tension portion 6500 is rotated so as to transfer the roll-to-roll material 950 at a speed of 1000mm per minute in accordance with the control signal of the roll-to-roll exposure control portion 8000, and the transfer servo motor 6040 constituting the first roller tension portion 6000 is rotated so as to transfer the roll-to-roll material 950 at a speed of 999mm per minute in accordance with the control signal of the roll-to-roll exposure control portion 8000.
The roll-to-roll exposure control unit 8000 receives and analyzes the transfer speed value detected (measured) by the material transfer speed detection sensor 6060 provided to the first roll tension unit 6000 and the transfer speed value detected (measured) by the material transfer speed detection sensor 6060 provided to the second roll tension unit 6500, respectively, to control each of the corresponding transfer servo motors so that the transfer speed value detected (measured) by the material transfer speed detection sensor 6060 provided to the first roll tension unit 6000 becomes larger.
Therefore, the first roller tension portion 6000 transfers the roll-to-roll material 950, which is transferred in the space between the first roller tension portion and the second roller tension portion 6500, in a flat and flat state without being dented.
The material exposure unit 7000 is provided at the lower end of the first roller tension unit 6000 and at the front end of the second roller tension unit 6500, and is provided at an intermediate position of the transfer table 2000.
The material exposure section 7000 stops the transfer of the roll-to-roll material 950 in response to the control signal, mechanically presses the roll-to-roll material 950 by pushing in the up-down direction, and forms a pattern on the surface of the roll-to-roll material 950 by air suction and driving an exposure lamp, thereby closely contacting the main film for forming a pattern.
In this case, the description is given in a manner that the photosensitive film is already attached to the surface of the roll-to-roll material 950, and it is understood that the same will apply hereinafter.
The material exposure section 7000 includes an exposure lamp 7100, a material pressing placement film 7200, a guide piston pin placement groove 7300, a placement film suction groove 7400, a material exposure guide piston pin 7500, a placement film pressing sealing rubber 7600, and a master glass main film 7700.
The exposure lamp 7100 emits ultraviolet rays (UV) according to a corresponding control signal of the roll-to-roll exposure control section 8000, and light emitting diodes which generate ultraviolet rays with an output of 1 watt (W) level or more are arranged so as to form intervals ranging from 0.5cm to 1cm in the horizontal and vertical directions, respectively. The light emitting diode is used, so that the power consumption is reduced.
The exposure lamp 7100 is composed of an upper exposure lamp 7102 and a lower exposure lamp 7104, and is activated for exposure in the case of manufacturing a flexible circuit board of a double-sided pattern, respectively, and is activated in the case of manufacturing a flexible circuit board of a single-sided pattern, and exposure may be performed by activating the upper exposure lamp 7102 and the lower exposure lamp 7104, respectively, in the case of manufacturing a flexible circuit board of a single-sided pattern, if necessary.
The upper exposure lamp 7102 and the lower exposure lamp 7104 are spaced apart from each other to be larger or smaller by a driving part not shown in the drawings according to a corresponding control signal of the roll-to-roll exposure control part 8000, and since such a structure is widely known, a more detailed description will be omitted.
The material pressing film 7200 is a transparent film, and is provided so that the lower surface of the upper exposure lamp 7102 adjacent to the upper surface of the roll-to-roll material 950 is fixed in a movable state, and the roll-to-roll material 950 can be pressed and fixed from the upper surface.
Guide piston pin placement grooves 7300 are formed along the periphery of the upper exposure lamp 7102, and material exposure guide piston pins 7500 are inserted to be placed so as not to move.
The film-placing suction grooves 7400 are formed in a groove shape disposed around and connected to the lower exposure lamp 7104, and adjacent objects are strongly sucked by external suction (suction). The placement film suction groove 7400 strongly presses the roll-to-roll material 950 positioned therebetween against the upper side of the lower exposure lamp 7104 in the process of strongly sucking the material against the placement film 7200.
The material exposure guide piston pin 7500 is formed along the periphery of the lower exposure lamp 7104, is arranged on the periphery of the position where the film suction groove 7400 is placed, and has a pin structure connected to a piston rod which moves in the up-down direction in accordance with a control signal from the roll-to-roll exposure control unit 8000.
A plurality of pins constituting the material exposure guide piston pin 7500 are respectively inserted into the piston pin guide holes 970.
When the pin of the material exposure guide piston pin 7500 is inserted into the piston pin guide hole 970, the roll-to-roll exposure control unit 8000 outputs a corresponding control signal to control the upper exposure lamp 7102 to slightly move upward, thereby facilitating the insertion.
When the pattern is exposed by transferring the roll-to-roll material 950 to the position of the material exposure unit 7000, if the rolling cylinders 6030 on both sides in the width direction of the first roller tension unit 6000 and the rolling cylinders 6030 on both sides in the width direction of the second roller tension unit 6500 are moved upward, the upper pressing roller 6010 constituting the first roller tension unit 6000 and the upper pressing roller 6010 constituting the second roller tension unit 6500 are moved upward.
In this case, the lower rotating roller 6020 constituting the first roller tension part 6000 and the lower rotating roller 6020 constituting the second roller tension part 6500 are released from being pressed, and the surface made of a rubber material slightly moves upward.
That is, in the process of moving upward the upper pressing roller 6010 constituting the first roller tension part 6000 and the upper pressing roller 6010 constituting the second roller tension part 6500, respectively, the lower rotating roller 6020 of the first roller tension part 6000 and the lower rotating roller 6020 of the second roller tension part 6500 which are pressed are restored. In this case, the roll-to-roll material 950 inserted (disposed) between each of the upper press rollers 6010 and the lower rotating roller 6020 is slightly lifted upward, and the insertion can be quickly and accurately performed as the piston pin guide hole 970 of the roll-to-roll material 950 is easily found by the corresponding pin of the material exposure guide piston pin 7500.
The first roller tension 6000 and the second roller tension 6500 are controlled and monitored in such a manner that the respective pins of the material exposure guide piston pin 7500 are accurately inserted into the piston pin guide holes 970 of the roll-to-roll material 950 in the range of 0.1 second to 0.5 second according to the respective control signals of the roll-to-roll exposure control unit 8000, and preferably, the respective rolling cylinders 6030 provided to the first roller tension 6000 and the second roller tension 6500, respectively, are controlled in such a manner as to be inserted for 0.2 second.
On the other hand, if the roll-to-roll exposure control unit 8000 determines that the corresponding pin of the material exposure guide piston pin 7500 is accurately inserted into the piston pin guide hole 970 of the roll-to-roll material 950 or a set time has elapsed, it outputs a corresponding control signal to the corresponding roll-pressing cylinder 6030 provided in the first roll tension unit 6000 and the second roll tension unit 6500, respectively, and moves the upper pressing roller 6010 provided in the first roll tension unit 6000 and the second roll tension unit 6500 downward.
A setting film pressing seal rubber 7600 is formed along the periphery of the lower exposure lamp 7104, and is provided in a space between the setting film suction groove 7400 and the material exposure guide piston pin 7500.
The placement film pressing seal rubber 7600 causes the roll-to-roll material 950 and the material pressing placement film 7200 to be in close contact with each other and blocks the suction force of the placement film suction groove 7400 from leaking to the outside.
The master glass master film 7700 is disposed in close contact with the upper surface of the lower exposure lamp 7104, functions as a master film in which a master pattern based on the same circuit pattern as the circuit pattern to be formed on the roll-to-roll material 950 is formed, and is made of glass.
When the circuit pattern to be formed on the roll-to-roll material 950 is changed, the original glass master film 7700 can be replaced.
The original glass master film 7700 may be additionally provided on the lower surface of the upper exposure lamp 7102 as necessary.
When the roll-to-roll material 950 is entered in response to a control signal from the roll-to-roll exposure control unit 8000, the material exposure unit 7000 fixes the roll-to-roll material 950 so as to be immovable by inserting the material exposure guide piston pin 7500 into the piston pin guide hole 970, and when the upper exposure lamp 7102 and the lower exposure lamp 7104 are brought into contact with each other, the set film suction groove 7400 strongly sucks the material and presses the set film 7200, so that the roll-to-roll material 950 and the original glass main film 7700 are brought into close contact with each other with no gap, and in this case, when the exposure lamp 7100 is turned on, a very fine circuit pattern to be formed is formed very precisely on the roll-to-roll material 950 without an error.
If it is determined that the roll-to-roll material 950 entered for pattern exposure has entered the material exposure section 7000 by the roll-to-roll exposure control section 8000 to a predetermined length and precisely reached the corresponding position, the material exposure guide piston pin 7500 moves up the plurality of pins included therein by driving the corresponding pistons in accordance with the corresponding control signal of the roll-to-roll exposure control section 8000, and maintains the state of moving up until the exposure step is finished. On the other hand, if the roll-to-roll exposure control unit 8000 determines that the exposure step is completed, the roll-to-roll exposure control unit 8000 controls the material exposure guide piston pin 7500 to drive the corresponding pin to return to the lower position.
The exposure lamp 7100 may be provided in such a manner as to discharge light to one of the upper and lower faces of the roll-to-roll material 950 or may be provided in such a manner as to discharge light to both faces simultaneously.
The material exposure section 7000 is inserted into a plurality of piston pin guide holes 970 formed at both side surface portions of the roll-to-roll material 950 during infrared ray exposure through a material exposure guide piston pin 7500 for making the roll-to-roll material 950 into which a pattern is to be entered and printed immovable, and the material exposure guide piston pin 7500 is driven according to a corresponding control signal of the roll-to-roll exposure control section 8000.
The material exposure section 7000 forms a fine and precise circuit pattern to be printed on the roll-to-roll material 950 on the original glass main film 7700, and when the roll-to-roll material 950 enters, the pattern is closely attached to the pattern, and the set film suction groove 7400 is driven in accordance with a control signal from the roll-to-roll exposure control section 8000, so that the roll-to-roll material 950 and the original glass main film 7700 are closely attached to each other without a gap.
The roll-to-roll exposure control section 8000 is provided at a part of the lower side of the transfer stage 2000, contacts each functional section constituting the system, and outputs a corresponding control signal and monitors the operation state by driving the operation program.
The roll-to-roll exposure control section 8000 may be driven alone by running a program or by a corresponding control instruction signal input from the outside.
On the other hand, the roll-to-roll exposure control unit 8000 monitors and controls the transfer speed of the roll-to-roll material 950 by the first roll tension unit 6000 to be slower than the transfer speed of the roll-to-roll material 950 by the second roll tension unit 6500. The adjustment of the transfer speed is performed by adjusting the pressing force with which the first roller tension portion 6000 and the second roller tension portion 6500 are pressed. The function of the roll-to-roll exposure control section 8000 will be described again in detail in the method description section.
The darkroom sealed cabinet portion 9000 houses and seals the entire high speed stamper linkage type roll-to-roll exposure system 900, blocking the inflow of light from the outside to the inside, and forcing the inflow of outside air to the inside through a filter process, which is illustrated in detail in fig. 8 of the drawings. On the other hand, a lamp for a dark room for performing work is provided inside the dark room sealing cabinet portion 9000, and a fan (fan) for blowing air into the inside and a high efficiency particulate air filter for blocking fine foreign matters from the outside are provided on the upper side surface of the outside. Fans and hepa filters for blocking fine substances and foreign substances are widely known, and more detailed description thereof will be omitted.
Fig. 9 is a flowchart illustrating an application method of the high-speed stamper linkage type roll-to-roll material exposure system according to an embodiment of the present invention, and fig. 10 is a diagram illustrating formation of a roll-to-roll material by an antenna pattern after an exposure process through an etching process and other processes according to an embodiment of the present invention.
Hereinafter, in the application method of the high-speed press-linked roll-to-roll exposure system 900 including the roll-to-roll exposure control unit 8000, which includes the unwinding guide table 1000, the transfer table 2000, the first foreign matter removal unit 3000, the second foreign matter removal unit 4000, the first pin hole guide roller 5000, the first roller tension unit 6000, the material exposure unit 7000, the second roller tension unit 6500, the second pin hole guide roller 5500, and the third foreign matter removal unit 4500, which are provided in this order, the roll-to-roll exposure control unit 8000 determines whether or not a signal or a command signal for performing an exposure process on the roll-to-roll material 950 is input (step S100), as described in detail with reference to the drawings.
When it is determined by the roll-to-roll exposure control unit 8000 that a command signal for exposing the roll-to-roll material 950 is input (step S100), the first pinhole guide roller 5000 is driven to horizontally transfer the roll-to-roll material 950 along the transfer table 2000 (step S110).
On the other hand, the roll-to-roll exposure control section 8000 drives the first foreign substance removal section 3000 to remove foreign substances for the first time (first stage) (step S120).
In this case, the second foreign substance removal unit 4000 manually and physically removes the foreign substance for the second time (second stage), and the third foreign substance removal unit 4500 manually and physically removes the foreign substance for the third time (third stage). That is, there is an advantage in that foreign matter on the surface of the roll-to-roll material 950 is removed in three stages.
The roll-to-roll exposure control unit 8000 analyzes the transfer speeds of the roll-to-roll material 950 measured by the first roll tension unit 6000 and the second roll tension unit 6500 (step S130).
The roll-to-roll exposure control unit 8000 determines whether the transfer speed of the second roller tension unit 6500 is faster or slower than the transfer speed of the first roller tension unit 6000 (step S140).
When the roll-to-roll exposure control unit 8000 determines that the transfer speed of the second roller tension unit 6500 is slower than the transfer speed of the first roller tension unit 6000 (step S140), the pressing pressure (push pressure) of the first roller tension unit 6000 is set to be smaller than the pressing pressure of the second roller tension unit 6500 (step S150).
That is, the transfer speed of the first roller tension unit 6000 is made slower, and the transfer speed of the second roller tension unit 6500 is made faster. The transfer speed is a speed at which the roll-to-roll material 950 is transferred.
As an example, it is preferable that the transfer speed of the first roller tension 6000 is set to 999m/m, the transfer speed of the second roller tension 6500 is set to 1000m/m, and the roll-to-roll material 950 is flatly unwound without being dented in the self-contained exposure portion 7000.
The roll-to-roll exposure control unit 8000 determines whether the transfer speed of the second roller tension unit 6500 is slower or faster than the transfer speed of the first roller tension unit 6000 (step S160). After the determination (step S160), if the transfer speed of the second roller tension portion 6500 is slower than the transfer speed of the first roller tension portion 6000, the process returns to repeat the above step S150, and if the transfer speed of the second roller tension portion 6500 is determined to be faster than the transfer speed of the first roller tension portion 6000, the subsequent steps are performed.
When it is determined by the roll-to-roll exposure control unit 8000 that the control signal for exposing the pattern to the roll-to-roll material 950 is input (step S170), the first pin hole guide roller 5000 and the second pin hole guide roller 5500 are controlled to interrupt the transfer of the roll-to-roll material 950, and the fixing pins provided in the material exposure unit 7000 are also driven together to set the roll-to-roll material 950 not to move. The roll-to-roll exposure control section 8000 causes a part of the material exposure section 7000 located on the upper surface and the lower surface to be pressed against the roll-to-roll material 950, thereby pressing the roll-to-roll material 950 against the surface on which the pattern is formed, and causes the roll-to-roll material 950 to be closely attached to the pattern precisely in a vacuum state by air suction. In this case, since the roll-to-roll exposure control section 8000 drives the exposure lamp 7100 provided in the material exposure section 7000, the pattern of the original glass main film 7700 is precisely exposed as in the case of the photosensitive film printed on the roll-to-roll material 950 (step S180).
On the other hand, if the roll-to-roll exposure control unit 8000 determines that the exposure of the material is continued (step S190), the process returns to the material transfer step (step S110), and if the exposure is not continued, the process ends.
Hereinafter, the high-speed press-linked roll-to-roll exposure system and the method of applying the same according to the present invention will be described in detail with reference to fig. 10, which shows a state in which the high-speed pressed roll-to-roll 950 after the exposure process forms an antenna pattern after being subjected to etching and other processes, which are not illustrated or described but are generally known. A plurality of holes are continuously formed at the same interval on one straight line at both side edge portions of the roll-to-roll material 950, and corresponding pins of the first pin hole guide roller 5000 and the second pin hole guide roller 5500 are inserted into the holes and transferred at a predetermined speed. Although the patterns printed by exposure are very fine and delicate, it can be confirmed that the patterns are each clearly divided and clearly formed.
The structure can screen out and remove foreign matters in the roll-to-roll material, accurately transfer the roll-to-roll material, accurately realize exposure for printing patterns on the roll-to-roll material, reduce production cost, prevent pattern separation phenomenon on the curved surface of the material, easily form fine patterns, enable the patterns to be very easy to deform, and prevent the patterns from being broken even if the materials are impacted due to the reasons of falling, etc.
While the specific embodiments of the present invention have been described in detail, it will be apparent to those skilled in the art that various changes and modifications can be made within the technical spirit of the present invention, and such changes and modifications fall within the scope of the claimed invention.
