Description

Lighting buckle

[0001] The present invention relates to a lighting buckle in which a tongue is fixed in an internal space, and more specifically, to a lighting buckle configured to send light to a character displayed in the center of a button module without interfering with an operating mechanism for fixing and releasing the tongue.

[0002] Various illuminated buckles are being proposed to facilitate fastening the seatbelt in a dark vehicle interior by installing a light directly on the button module or by providing a light inside the buckle and guiding the light to the push button to emit it outward, thereby allowing the user to easily find the push button to fasten the seatbelt.

[0003] The lighting buckle is composed of many components to fix and release the tongue within a narrow interior space and to emit light to the outside.

[0004] In particular, many parts for fixing and releasing the tongue inserted into the buckle, such as the buckle assembly including the fixed latch, ejector, and elastic member, are located in the center of the narrow interior space.

[0005] Due to the spatial limitations described above, conventional lighting buckles generally have the limitation that the components for emitting light to the outside are arranged to avoid the center of the internal space of the buckle so as not to interfere with the introduction and withdrawal of the tongue within the buckle, and therefore, even when the light is turned on, the area near the edge of the push button is inevitably illuminated.

[0006] Therefore, a method to solve these problems is required.

[0007] The present invention is an invention devised to solve the problems of the aforementioned prior art, and the present invention has the objective of providing a lighting buckle capable of sending light to a character displayed in the center of a button module without interfering with the operating mechanism for fixing and detaching the tongue.

[0008] The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the description below.

[0009] A lighting buckle according to one embodiment of the present invention for achieving the above-described purpose comprises: a button module in which light is emitted to the outside in at least one area, and a lighting module for irradiating light to the button module, wherein the area of ​​the button module in which light is emitted to the outside may be a character displayed in the central part of the button module.

[0010] The above lighting module may include a light emitting unit that emits light; and a light induction unit for irradiating light incident from the light emitting unit onto characters displayed in the central portion of the button module.

[0011] The above button module may have areas where light does not pass through covered opaquely so that the inside of the buckle is not visible when the above lighting module is turned off.

[0012] The above button module may include: a contact unit located on the outer side of the buckle and made entirely of a transparent material, including a first display portion on which a character is displayed; and a blocking unit provided on one side of the contact unit to face the lighting module, made of an opaque material, and including a second display portion on which a character is displayed in a cut-out form.

[0013] The above blocking unit may be made of PC material.

[0014] The first display part and the second display part may be provided in mutually opposing character forms.

[0015] One side of the above contact unit is located on the outside of the buckle, and the opposite side is recessed so that the blocking unit can be inserted.

[0016] The first display part can be inserted into the second display part of the blocking unit by protruding toward the other surface of the contact unit.

[0017] The above button module may further include a connection unit that is fixed inside the buckle and is connected so that the contact unit and the blocking unit are inserted into the buckle and then returned.

[0018] The above connecting unit may have a connecting portion formed opposite the blocking unit so that the blocking unit to which the contact unit is connected can slide, and an opening may be formed on one side of the connecting portion so that a path of light from the lighting module toward the button module can be formed.

[0019] The above lighting module is arranged to irradiate light toward the first display portion and the second display portion from the upper portion of the above connecting unit, and the opening portion can be formed at the upper portion of the above connecting unit.

[0020] The above button module may have the contact unit and the blocking unit formed by double injection molding.

[0021] The above lighting module may be arranged to emit light to letters displayed in the center of the button module without interfering with the operating mechanism for fixing and releasing the tongue.

[0022] The above light-inducing unit can be bent at least once in a direction toward the letters of the button module at a position opposite to the buckle unit for fixing and releasing the tongue within the internal space.

[0023] The above-mentioned light-inducing unit is formed long from one end to the other on a surface facing the buckle unit within the internal space, and can be bent at a preset angle in the direction facing the letters of the button module at the other end.

[0024] The above-mentioned light-inducing unit may have a downward slope of 15 to 26 degrees from one end to the other end, based on the longitudinal axis, toward the letters of the button module.

[0025] The above light-inducing unit can be fixed by fitting it onto the upper surface of the internal space.

[0026] The light-emitting unit can be fixed in close contact with the surface of the light-inducing unit facing the buckle assembly.

[0027] The above-mentioned light-inducing unit is formed long in a direction toward the buckle group at a position facing and spaced apart from the buckle group within the internal space, and can be vertically bent at least once in a direction toward the letters of the button module at an end.

[0028] The light-inducing unit can be fixed to the lower part of the light-emitting unit fixed to the upper surface of the internal space.

[0052] As illustrated in FIGS. 1 to 3, a lighting buckle (10) according to one embodiment of the present invention is a buckle in which a tongue is fixed in an internal space, and may largely include a button module (100) and a lighting module (200).

[0053] First, the button module (100) can facilitate wearing the seatbelt in a dark vehicle by allowing light to leak out in at least one area.

[0054] Specifically, the area where light leaks out from the button module (100) may be a character displayed in the center of the button module (100).

[0055] At this time, the button module (100) may have a cut portion formed so as not to interfere with the tongue inserted into the buckle.

[0056] In other words, a luminous character is displayed in the central part of the button module (100), and a cut portion can be formed at the bottom of the character.

[0057] And, by irradiating light through the aforementioned button module (100) with the lighting module (200), light can be emitted to the outside through the button module (100).

[0058] The lighting buckle (10) according to one embodiment of the present invention described above may be provided with a buckle assembly (B) inside a lower cover (CL), and a button module (100) may be provided to be drawn inward and then returned by an external force in front of the buckle assembly (B) inside the lower cover (CL).

[0059] For example, a lighting buckle (10) according to one embodiment of the present invention may have an operating mechanism in which a lower cover (CL) and an upper cover (CU) are combined to form an internal space, and a tongue is inserted into the internal space and fixed to a buckle assembly (B), or is detached from the buckle assembly (B) and pulled out to the outside of the internal space.

[0060] That is, a buckle assembly (B) is provided inside the lower cover (CL), and a button module (100) can be pulled inward and then returned by an external force based on the buckle assembly (B) inside the lower cover (CL).

[0061] In addition, a covering (R) is fixed in the space between the lower cover (CL) and the buckle to prevent foreign matter from entering the front interior of the buckle.

[0062] In other words, a button module (100) and a covering (R) may be located on the front side of the combined upper cover (CU) and lower cover (CL).

[0063] In addition, although not shown in the drawing, a sleeve (not shown) is provided on the rear side of the combined upper cover (CU) and lower cover (CL) to protect the wires of the lighting module (200) and to prevent foreign substances from entering the internal space of the lighting buckle (10).

[0064] The buckle assembly (B) described above includes an elastic member capable of elastic deformation and elastic recovery to fix and release a tongue inserted into the buckle, and is equipped with a fixing latch and an ejector to fix and release the tongue described above, and may be provided so that the elastic member can be inserted.

[0065] The above-described buckle assembly (B) can be problematic because the elastic member may experience buckling, which shortens its lifespan and increases the time and cost required to replace it. Therefore, for example, one insertion groove where the load applied to fix the tongue to the buckle assembly (B) is more concentrated is formed deeper than the depth of another insertion groove, thereby creating a length difference equal to the pitch of the elastic member, so that the buckling phenomenon caused by the elastic member can be prevented.

[0066] At this time, the aforementioned buckle assembly (B) is configured to allow the buckle to be locked and unlocked so that the driver can easily fasten or unfasten the seatbelt, and it is desirable that the buckle be configured so that unlocking does not occur due to unexpected external impact.

[0067] Here, if the above-described functions can be performed, the materials of the above-described covering (R), upper cover (CU), lower cover (CL), and light induction unit (240) may vary, and it is obvious that the scope of the present invention is not limited by this.

[0068] However, for a more detailed explanation, the covering (R) may be made of PC and ABS materials, and the upper cover (CU) and lower cover (CL) may be made of PP material.

[0069] In a lighting buckle (10) according to one embodiment of the present invention having the structure described above, the button module (100) is,

[0070] When the lighting module (200) is turned off, the area where light does not pass through can be covered opaquely so that the inside of the buckle is not visible.

[0071] Specifically, so that the inside of the buckle is not visible when the lighting module (200) is turned off, the button module (100) may be provided with at least one of the multiple members to be combined in an opaque material such as PC or ABS.

[0072] And the button module (100) may have a structure in which a contact unit (120) made of a transparent material and a blocking unit (140) made of an opaque material are connected to each other.

[0073] For example, as illustrated in FIG. 4, the above-described button module (100) may be configured to include a contact unit (120) and a blocking unit (140) so that light leaks out only from the character formed on the central side of the button module (100).

[0074] Specifically, the contact unit (120) is located on the outside of the buckle, and a first display part (121) with a character displayed on it may be formed.

[0075] The contact unit (120) is located on the outside of the buckle as shown in FIGS. 3 and 4, and may be made of a transparent material including a first display part (121) on which a character is displayed.

[0076] Here, if the contact unit (120) can be made of a transparent material, the color material may vary, and the scope of the present invention is not limited by this.

[0077] However, for further detailed explanation, the contact unit (120) may be made of transparent ABS (Acrylonitrile Butadiene Styrene) material with a reddish color.

[0078] The blocking unit (140) connected to the contact unit (120) described above is provided with an opaque material as described above, and a second display part (141) through which a character is displayed can pass.

[0079] And, the contact unit (120) can be connected to one side of the contact unit (120) so as to face the lighting module (200).

[0080] As described above, the contact unit (120) is formed with a cut portion to prevent interference of the inserted tongue, and the blocking unit (140) connected thereto may also be formed with a cut portion corresponding to the cut portion of the contact unit (120).

[0081] In addition, a second display portion (141) is formed on a blocking unit (140) provided on one side of the contact unit (120) so as to face the lighting module (200), and the second display portion (141) can be displayed by being cut out in the form of characters corresponding to the characters of the first display portion (121) on the blocking unit (140).

[0082] To summarize, the first display portion (121) and the second display portion (141) can be positioned facing each other in the center of the button module (100), and a cut portion can be formed at the bottom of the first display portion (121) and the second display portion (141).

[0083] And, with the first display part (121) and the second display part (141) facing each other, the same character can be formed in relief and intaglio, respectively.

[0084] Here, if the blocking unit (140) can be made of an opaque material, the color material can be varied, and it will be obvious that the scope of the present invention is not limited due to this.

[0085] However, for a more detailed explanation, for example, the blocking unit (140) would be conveniently made of a white PC (polycarbonate) material.

[0086] Next, the structure for illuminating the letters displayed in the center of the button module (100) without interfering with the inlet and outlet of the tongue when the lighting module is turned on is examined in detail as follows.

[0087] At this time, the first display unit (121) of the contact unit (120) and the second display unit (141) of the blocking unit (140) can be provided in the form of mutually opposing letters as described above.

[0088] For detailed explanation, an alphabet signifying pressing is shown on the drawing, but the characters formed on the first display part (121) of the contact unit (120) and the second display part (141) of the blocking unit (140) are not limited thereto and may be pictograms, hieroglyphs, ideograms, or ideograms, and in some cases may be provided as phonetic characters including phonemic characters and syllabic characters.

[0089] The above-described contact unit (120) is specifically positioned on one side outside the buckle, and the opposite side is sunken so that a blocking unit (140) can be inserted toward the opposite side.

[0090] At this time, the first display part (121) may be provided in a form that protrudes toward the second display part (141) from the other side of the contact unit (120) and is inserted into the second display part (141) of the blocking unit (140).

[0091] In the button module (100), the connection between the contact unit (120) and the blocking unit (140) may also vary, and although this does not limit the scope of the present invention, forming the contact unit (120) and the blocking unit (140) by double injection molding can be simple and improve productivity.

[0092] Accordingly, when the lighting module (200) is turned on, the letters displayed in the center of the button module (100) can be illuminated.

[0093] At this time, the button module (100) may further include a connection unit (160) so that the character displayed in the center of the button module (100) can be emitted without interfering with the operating mechanism of the tongue being drawn into the internal space and drawn out to the outside.

[0094] The connection unit (160) can be connected so that the contact unit (120) and the blocking unit (140) can be inserted into the buckle and then returned.

[0095] Specifically, the connecting unit (160) may be positioned in front of the buckle assembly (B) described above inside the button, and the connecting unit (160) may also be fixed inside the lower cover (CL) of the buckle having a penetrating area in the longitudinal direction along the direction of movement of the tongue so as not to interfere with the movement of the tongue inserted into the buckle.

[0096] At this time, a coupling portion facing the blocking unit (140) may be formed in front of the connecting unit (160) so that the blocking unit (140) to which the contact unit (120) is connected can slide.

[0097] In addition, the connection unit (160) can be provided so that a path of light can be formed from the lighting module (200) toward the button module (100).

[0098] In other words, so as not to interfere with the light irradiated from the light-inducing unit (240) toward the button module (100), the connecting unit (160) may have an opening (162) formed on one side of the connecting part.

[0099] To explain more specifically with reference to the drawing, the connecting unit (160) can be penetrated from the front to the rear so as not to interfere with the tongue, and a penetration area can be formed along the length direction.

[0100] And, based on the above-described penetration area, at least a portion of the upper side can be cut to form an opening (162).

[0101] That is, an opening (162) can be formed at the upper portion of the connecting unit (160).

[0102] Accordingly, the light directed from the lighting module (200) toward the button module (100) and the connection unit (160) can be prevented from interfering due to the above-described opening (162).

[0103] In addition, a pair of connecting parts are provided on both sides of the front side along the longitudinal direction through which the blocking unit (140) is connected, so that the blocking unit (140) connected to the contact unit (120) can slide.

[0104] As a result, in the process of guiding the light emitted from the light-emitting unit (220) to the button module (100) through the light-guiding unit (240), the lighting module (200) can emit light toward the first display part (121) and the second display part (141) of the button module (100) from the upper part of the connection unit (160) without interference between the light and the tongue.

[0105] Accordingly, the lighting buckle (10) according to one embodiment of the present invention having the above-described configuration has the advantage that when the lighting module (200) is turned on, the character displayed in the central part of the button module (100) can be illuminated without interfering with the insertion and withdrawal of the tongue.

[0106] At this time, the lighting module (200) described above may include the following configuration so as to be organically connected to the structure of the button module (100) described above, so as to be able to send light to the character displayed in the center of the button module (100) without interfering with the operating mechanism for fixing and detaching the tongue.

[0107] Specifically, the lighting module (200) includes a light-emitting unit (220) and a light-inducing unit (240).

[0108] The light-emitting unit (220) may be provided as a device that emits light when current is applied, such as a light-emitting diode, and may be placed in an internal space so that the emitted light is incident on the light-inducing unit (240).

[0109] At this time, the light-inducing unit (240) can irradiate the light incident from the light-emitting unit (220) described above onto the character displayed in the center of the button module (100).

[0110] For example, the lighting module (200) described above can be provided on the upper part of the buckle assembly (B).

[0111] Also, the light induction unit (240) can be made of PC material.

[0112] As illustrated in FIGS. 8 to 11, the light-inducing unit (240) may be arranged to be bent at least once in the direction toward the character of the button module (100) at a position opposite to the buckle assembly (B) for fixing and releasing the tongue.

[0113] Here, the position facing the buckle assembly (B) for fixing and releasing the tongue may be a position spaced apart from the buckle assembly (B).

[0114] For example, the light-inducing unit (240) can be formed extending from one end to the other on a surface facing the buckle assembly (B) within the internal space.

[0115] At this time, the surface facing the buckle unit (B) described above may be at a position spaced apart from the buckle unit (B).

[0116] And, it can be bent at a preset angle toward the letter of the button module (100) at the other end.

[0117] Here, if the light-guiding unit (240) is bent so that light can leak out from the character provided in the button module (100), the angle range in which the light-guiding unit (240) is bent may vary, and it is obvious that the scope of the rights of the present invention is not limited by this.

[0118] However, for a more detailed explanation, if the light-guiding unit (240) is provided on the upper part of the buckle assembly (B), the light-guiding unit (240) may have a downward slope of 15 to 26 degrees from the other end toward the character of the button module (100) with respect to the length axis (X) from one end to the other end.

[0119] At this time, the light induction unit (240) can be fitted and fixed to the upper surface of the internal space.

[0120] The light-guiding unit (240) may include a base (241), a bending part (242), and a refraction part (243).

[0121] The base (241) can be formed long from one end to the other.

[0122] And, the bending portion (242) is arranged to be bent in a direction toward the button module (100) from the other end of the base (241) described above, so that the bending portion (243) described later can be arranged facing each other at a position adjacent to the button module (100).

[0123] At this time, the refractive part (243) can perform the function of collecting light and sending it to the text of the button module (100) when light incident on one end of the base (241) by the light-emitting unit (220) is guided to the other end of the base (241).

[0124] The above-described bending portion (243) may be provided in a form in which a plurality of protruding pieces are arranged facing the button module (100) at the bending portion (242).

[0125] Here, the protruding shape of the protruding piece may also vary, and it should be understood that the scope of the present invention is not limited by this.

[0126] However, it would be effective to provide the protruding part in a semi-cylindrical shape, such as a cylinder with a crescent-shaped cross-section.

[0127] Additionally, if light can be spread evenly to the character portion through the refractive part (243), a plurality of protruding pieces can be arranged in one direction as shown in the drawing, and can be modified in various other forms not shown in the drawing, and thus the scope of the present invention is not limited.

[0128] However, to explain the variation for more detailed explanation, a pattern can be formed on one side of the light-guiding unit (240) through an etching process or an etching process without a separate refraction part (243).

[0129] That is, a refractive part (243) may be formed protrudingly on the light-guiding unit (240), but by forming a pattern on one side of the light-guiding unit (240) through an etching process or an etching process, light can be spread evenly to the character part of the button module (100).

[0130] And, a first fixing hole (244) may be provided at the end of the base (241) to correspond to the number and position of the first protrusion (CU3).

[0131] At the end of the base (241) described above, a first protrusion (CU3) formed in the upper cover (CU) can be inserted and fixed.

[0132] In addition, a step (CU1) is formed on the upper cover (CU) to determine the position of the end of the base (241), thereby limiting the impact applied to the first protruding hole (CU3) by the sliding insertion of the first fixing hole (244).

[0133] Additionally, a second fixing hole (245) is formed on both ends of the base (241) so that it can be slid into a second protruding hole (CU2) formed in the upper cover (CU).

[0134] For the sliding insertion described above, the second protrusion (CU2) is provided in a symmetrical shape, and when the base (241) is slid into a preset position, the protrusion formed in the second protrusion (CU2) is inserted into the second fixing hole (245) formed on both ends of the base (241) so as to be fixed more stably.

[0135] At this time, the periphery of the second fixing hole (245) on both ends of the base (241) is provided with a reinforcing part (246) that protrudes outward to reinforce the periphery of the second fixing hole (245) and increase the bonding strength, so that the light induction unit (240) can be stably engaged and fixed to the upper surface of the upper cover (CU).

[0136] The above-described reinforcing member (246) can be easily attached and detached by being provided in a shape that curves outward with respect to the base (241).

[0137] That is, the above-described reinforcing member (246) is provided in a shape that is curved outward with respect to the base (241), so that the user can easily catch a finger or tool during the attachment and detachment process, and interference and friction are alleviated by the curvature shape, so that the attachment and detachment can be made smooth.

[0138] At this time, the light-emitting unit (220) can be fixed in close contact with the lower surface of the light-inducing unit (240) having the shape described above.

[0139] In other words, the light-emitting unit (220) can be fixed in close contact to one surface of the light-inducing unit (240) facing the buckle assembly (B) having the shape described above.

[0140] That is, one side of the light-inducing unit (240) to which the light-emitting unit (220) is closely fixed may be a side facing the buckle assembly.

[0141] Accordingly, light can be emitted to the outside through the character provided in the center of the button module (100) by the light-emitting unit (220) and light-inducing unit (240) of the lighting module (200) described above.

[0142] Meanwhile, if the letters displayed in the center of the button module (100) can be illuminated without interfering with the introduction and withdrawal of the tongue when the lighting module (200) is turned on, the light-inducing unit (240) can be provided in various forms in response to changes in the position of the light-emitting unit (220).

[0143] For example, as a modified example as illustrated in FIG. 12, the light induction unit (240-1) in the lighting module (200-1) can be formed long in a direction toward the buckle group (B) at a position facing the buckle group (B) in the internal space.

[0144] At this time, as described above, the position of the light-inducing unit (240-1) facing the buckle assembly (B) may be a position spaced apart from the buckle assembly (B) within the internal space.

[0145] That is, within the internal space described above, the light-inducing unit (240-1) can be formed long toward the buckle group (B) at a distant location facing the buckle group (B).

[0146] Additionally, the end of the light-inducing unit (240-1) may be provided in a form that is vertically bent at least once in the direction toward the letters of the button module (100).

[0147] For example, if the light emitting unit (220) is fixed to the upper surface of the internal space, that is, the inner surface of the upper cover (CU), then the light guiding unit (240) is positioned below the light emitting unit (220), and at this time, one end of the light guiding unit (240) may be bent vertically, and the other end may be bent to have a downward slope as described above.

[0148] Furthermore, if the light emitting unit (220) is placed at the rear with respect to the buckle assembly (B) described above in order to utilize the internal space of the narrow lighting buckle (10), the light guiding unit (240) may be bent at multiple points and arranged in a step shape, but it will all fall within the scope of the present invention.

[0149] Additionally, in some cases, the light-inducing unit (240) may be provided so that the direction of irradiating light can be changed from the initial position to forward, backward, left, or right.

[0150] For example, even if the button module (100) is divided to display multiple characters and light is irradiated to each character among the multiple characters as needed, it will all fall within the scope of the present invention.

[0151] In addition, by providing a reflection unit or a light collection unit on the left and right sides of the interior space of the lighting buckle (10), it may be possible to prevent light from being irradiated to any part other than the letters.

[0152] Accordingly, the lighting buckle (10) according to one embodiment of the present invention having the above-described configuration is designed so that no physical interference occurs during the process of the tongue being inserted or withdrawn when the lighting module (200) is turned on as shown in FIG. 13, thereby having the effect of ensuring both safety and reliability at the same time.

[0153] In particular, by making the characters displayed in the central area of ​​the button module (100) clearly illuminated, the user can intuitively recognize the corresponding character information, which provides high readability even in conditions where visibility is limited, such as in a driving environment or a dark indoor environment.

[0154] Beyond simply identifying character shapes, blurring of character boundaries and light scattering are minimized, allowing users to reliably select their desired functions.

[0155] Furthermore, since the lighting operation mechanism and the button operation mechanism are completely separated, the durability and reliability of the lighting buckle are enhanced, and there is the advantage of consistent performance even with repeated use.

[0156] In addition, as shown in FIG. 14, when the lighting module (200) is turned off, an opaque area that does not transmit light is appropriately arranged to prevent the internal structure of the buckle from being directly exposed from the outside.

[0157] The aforementioned opaque blocking effect makes the surface of the button module (100) appear as a single, complete surface in appearance, thereby preventing the complex shape or gaps of the internal parts from being exposed to the user's eyes.

[0158] As a result, users perceive the entire button module as a luxurious surface with a unified color and texture, which enhances the design completeness of the product and provides both a sense of luxury and aesthetic appeal.

[0159] In particular, the opaque blocking layer blocks afterglow or shadowing phenomena that may occur when external light enters the interior, thereby maintaining a uniform color even when the lighting module (200) is turned off and the button module (100) is turned off.

[0160] As a result, even when the lighting module (200) is turned off, the user can experience a neat and tidy appearance of the button module (100), which further enhances the overall product value of the device.

[0161] Furthermore, through the aforementioned configuration, the present invention demonstrates significant effects not only in functional aspects but also in aesthetic and practical aspects.

[0162] For example, the text illumination of the button module (100) improves user's visual guidance and ease of operation, and the opaque blocking effect provides a sophisticated and integrated appearance.

[0163] Therefore, it enables the device to go beyond being a simple functional component and provide design satisfaction in various application fields, such as high-end electronic devices or automotive interior materials.

[0164] Furthermore, since the visual transition according to the on and off states of the lighting module (200) is clearly distinguished, the user can intuitively check the state when the lighting buckle (10) according to one embodiment of the present invention is turned on and when it is turned off.

[0165] In other words, the lighting buckle (10) of the present invention is not merely a light-emitting component, but can be said to provide a technological advancement that simultaneously ensures reliability and aesthetics in the overall usage environment.

[0166] Having described preferred embodiments of the invention, it will be apparent to those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or scope thereof, in addition to the embodiments described above.

[0167] Therefore, the above-described embodiments should be considered as illustrative rather than restrictive, and accordingly, the present invention is not limited to the above description but may be modified within the scope of the appended claims and their equivalents.

[0168] In other words, the embodiments of the present invention are not implemented only through the above-described devices and / or operating methods, but may also be implemented through a program for realizing a function corresponding to the configuration of the embodiments of the present invention, a recording medium on which the program is recorded, etc., and such implementation can be easily implemented by a specialist in the technical field to which the present invention pertains based on the description of the embodiments described above. Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements made by those skilled in the art using the basic concept of the present invention defined in the following claims also fall within the scope of the present invention.
