[0001] Embodiments of the present invention relate to an information output device.

[0002] Users can perceive information in a variety of ways. To achieve this, various types of information output devices are used.

[0003] For example, visual information output devices using printed materials and auditory information output devices using sound are being used.

[0004] In particular, in modern times, with the increase in information volume and technological advancement, information output devices that include electronic technology are being widely used, and display devices with a large number of pixels are commonly used as visual information output devices.

[0005] However, in the case of these display devices, various circuits are built in, which reduces the feasibility of manufacturing and causes inconvenience in control.

[0006] Meanwhile, technological advancements and diversification of lifestyle habits are leading to a demand for diverse forms of information output.

[0007] For example, users may require different information output devices depending on their specific circumstances. In particular, users with impaired senses, such as those with poor or no visual acuity, may require tactile information output. Tactile information output presents challenges in easily controlling and ensuring stable operation, limiting the potential for improved user convenience through improvements in information output devices.

[0008] Embodiments of the present invention provide an information output device capable of improving the precision control capability of information output and the efficiency of information output.

[0010] In addition, the driving force providing unit includes a driving support unit formed by extending in one direction and a coil unit formed by being wound around the driving support unit, and the driving force limiting member can be arranged to overlap at least a portion of the coil unit.

[0011] Additionally, the driving force limiting member may be formed to have a height along the longitudinal direction of the driving support member.

[0012] Additionally, the driving force limiting member may be formed to have a height that overlaps at least a portion of the motion unit.

[0013] Additionally, the motion unit can be formed to rotate in at least one direction by a magnetic field formed from the coil portion when an electric field is applied to the coil portion.

[0064] In order to achieve the above object, one aspect of the present invention may include an expression unit that moves in at least one direction so as to be sensed by a user, a movement unit disposed on one side of the expression unit, formed to be rotatable in at least one direction, and moving the expression unit in at least one direction while rotating, a driving force providing unit disposed on one side of the movement unit and providing driving force to the movement unit, and a driving force limiting member formed to reduce or limit transmission of driving force generated from the driving force providing unit in a direction other than the direction toward the expression unit.

[0065] The present invention is capable of various modifications and embodiments. Specific embodiments are illustrated in the drawings and described in detail in the detailed description. The effects and features of the present invention, as well as the methods for achieving them, will become clearer with reference to the embodiments described in detail below, along with the drawings. However, the present invention is not limited to the embodiments disclosed below and can be implemented in various forms.

[0066] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. When describing with reference to the drawings, identical or corresponding components are given the same reference numerals and redundant descriptions thereof will be omitted.

[0067] In the examples below, the terms first, second, etc. are not used in a limiting sense, but are used for the purpose of distinguishing one component from another.

[0068] In the examples below, singular expressions include plural expressions unless the context clearly indicates otherwise.

[0069] In the examples below, terms such as “include” or “have” mean that a feature or component described in the specification is present, and do not preclude the possibility that one or more other features or components may be added.

[0070] For convenience of explanation, the sizes of components in the drawings may be exaggerated or reduced. For example, the sizes and thicknesses of each component shown in the drawings are arbitrarily indicated for convenience of explanation, and thus the present invention is not necessarily limited to what is shown.

[0071] In the following examples, the x-axis, y-axis, and z-axis are not limited to three axes on an orthogonal coordinate system, and can be interpreted in a broad sense that includes them. For example, the x-axis, y-axis, and z-axis may be orthogonal to each other, but may also refer to different directions that are not orthogonal to each other.

[0072] In some embodiments, where implementations are otherwise feasible, specific process sequences may be performed in a different order than described. For example, two processes described in succession may be performed substantially simultaneously, or in a reverse order from the described order.

[0073] FIG. 1 is a perspective view schematically illustrating an information output device according to one embodiment of the present invention.

[0074] Figure 2 is a schematic drawing for explaining the information output device of Figure 1.

[0075] Referring to FIGS. 1 and 2, the information output device (1000) of the present embodiment may include an expression unit (1110) and a driving force providing unit (DCU).

[0076] The expression unit (1110) is formed so as to be able to move in at least one direction (e.g., the Z-axis direction of FIG. 1), and can be formed and arranged so as to be able to rise and fall in one direction (e.g., the Z-axis direction of FIG. 1).

[0077] The driving force providing unit (DCU) can be configured to provide driving force to the expression unit (1110) so that the expression unit (1110) can perform a movement, for example, an upward or downward movement.

[0078] As a specific example, the expression unit (1110) may be exposed through an opening (1001TH) on the upper surface of the housing (1001) and may be arranged to have a protruding shape when raised.

[0079] Through the rising and falling movement of the expression unit (1110), the user can sense the expression unit (1110), and for example, the expression surface (1111) of the expression unit (1110) can be sensed using the sense of touch, so that information interaction such as the user's information sensing or information input can proceed. As an optional embodiment, the sensing of the expression unit (1110) is not limited to the sense of touch and may also be visual sensing.

[0080] As an optional embodiment, the information output device (1000) of the present embodiment may include a plurality of expression units (1110). In addition, it may additionally include a plurality of driving force providing units (DCUs) corresponding to each of the plurality of expression units (1110).

[0081] Although not shown in FIGS. 1 and 2, a drive unit (or drive section) may be further arranged as an optional embodiment, and the drive unit may be formed to transmit the drive force generated from the drive force providing unit (DCU) to the expression unit (1110), and may be formed to move in at least one direction.

[0082] FIG. 3 is a cross-sectional view illustrating one embodiment of a driving force providing unit of the information output device of FIGS. 1 and 2.

[0083] The driving force providing unit (DCU) may include a coil unit (1020), and as an example, the coil unit (1020) may be arranged around the driving support unit (1070). As a specific example, the coil unit (1020) may have a form wound around the driving support unit (1070).

[0084] When an electric field is applied to the coil portion (1020), current flows through the coil portion (1020) and a magnetic field may be formed around the coil portion (1020). Through this magnetic field, a driving force may be provided to cause the expression portion (1110) to rise and protrude or, conversely, to descend.

[0085] The drive support member (1070) includes an elongated region and can be positioned to penetrate the coil member (1020).

[0086] The drive support (1070) can be formed of various materials, and may be formed of a lightweight and durable plastic material.

[0087] As an example, the drive support (1070) may include metal.

[0088] As an optional embodiment, the driving support member (1070) may include a magnetic material, and as a specific example, the entirety or an upper portion thereof may contain the magnetic material. This allows the magnetic field size to be increased when a magnetic field is generated through the coil member (1020), and the generation of the magnetic field can be efficiently performed, thereby improving the efficiency of providing driving force for the movement of the expression member (1110).

[0089] As an example, the drive support (1070) may include iron. As another example, the drive support (1070) may include nickel or cobalt.

[0090] A driving force limiting member (1090) may be arranged on at least one side of the driving force providing unit (DCU). For example, the driving force limiting member (1090) may be arranged on one outer side of the coil unit (1020). As a specific example, the driving force limiting members (1090) may be arranged on both outer sides of the coil unit (1020), thereby allowing the coil unit (1020) to be arranged between the driving force limiting members (1090) on both sides.

[0091] As an optional embodiment, the driving force limiting member (1090) may be arranged to surround at least one area of ​​the outer surface of the coil section (1020).

[0092] In addition, as a specific example, the driving force limiting member (1090) may be formed long enough to correspond to the upper end of the coil portion (1020) based on the height direction of the coil portion (1020).

[0093] The driving force limiting member (1090) can reduce or block the transmission of driving force generated from the driving force providing unit (DCU) in a direction intersecting the direction from the driving force providing unit (DCU) toward the expression unit (1110). Through this, the transmission efficiency of the driving force from the driving force limiting member (1090) toward the expression unit (1110) can be improved, interference between members in adjacent areas can be reduced, and as an optional embodiment, when a plurality of driving force limiting members (1090) are arranged, the transmission or interference of driving force toward each other can be reduced or blocked, thereby improving the overall driving efficiency of the information output device (1000), improving the driving balance characteristics, and improving the precise control capability.

[0094] In addition, in other words, the driving force providing unit (DCU) uses the magnetic field generated in the coil unit (1020), reduces or blocks the transmission of this magnetic field to the adjacent side space, and effectively allows the force of the magnetic field to reach the expression unit (1110) from the coil unit (1020).

[0095] The driving force limiting member (1090) can reduce or prevent the magnetic field generated through the coil unit (1020) from interfering with an adjacent space or from interfering with an adjacent space. For example, it can reduce or shield the interference of the magnetic field in the direction away from the side of the coil unit (1020) (X-axis direction in the drawing), and can precisely control the movement of the expression unit and improve the efficiency of the movement by strengthening the directionality of the magnetic field toward the expression unit. Through this, when another member adjacent to one driving force providing unit (DCU), for example, another driving force providing unit (DCU), is arranged, the interference of abnormal mutual magnetic fields between them can be reduced.

[0096] The driving force limiting member (1090) can be formed of various materials and may contain, for example, a metal material.

[0097] The driving force limiting member (1090) may be formed of a material that affects the magnetic field generated from the coil section (1020), and may contain, for example, a magnetic material. As a specific example, it may contain iron, nickel, cobalt, and various other magnetic materials.

[0098] Figure 4 is a drawing illustrating a modified example of Figure 3.

[0099] Referring to FIG. 4, the driving force limiting member (1090') has a longer form than the driving force limiting member (1090) of FIG. 3, and may be formed, for example, to extend past the upper end based on the height direction of the coil portion (1020). As a specific example, the driving force limiting member (1090') may be formed to correspond to the upper end based on the height direction of the driving support portion (1070). By forming the driving force limiting member (1090') so as to extend past the coil portion (1020), the effect of reducing or preventing the magnetic field generated through the coil portion (1020) from interfering with an adjacent space or from interfering with an adjacent space can be enhanced. In addition, by strengthening the directionality of the magnetic field generated from the coil portion (1020) toward the expression portion, the movement of the expression portion can be precisely controlled, the efficiency of the movement can be improved, and the movement speed of the expression portion can be improved.

[0100] Fig. 5 is an exemplary plan view of the driving force providing unit of Fig. 3 viewed from one direction.

[0101] For example, FIG. 5 may be a plan view viewed from the top of FIG. 3. Referring to FIG. 5, the driving force limiting member (1090) may have a shape surrounding the coil portion (1020) and may have a hollow column shape, specifically, a hollow cylinder shape.

[0102] In Fig. 5, the driving force limiting member (1090) and the coil portion (1020) are spaced apart, but depending on the design conditions, the driving force limiting member (1090) may have an area in contact with the coil portion (1020) if necessary.

[0104] Referring to FIG. 6, the driving force limiting member (1090) may have a shape that surrounds the coil portion (1020), and may have a hollow column shape, for example, a hollow square column shape. Although not shown, the driving force limiting member (1090) may have various column shapes, and may have a hollow column shape with various polygonal bottom shapes.

[0108] The first driving force providing unit (DCU1) and the second driving force providing unit (DCU2) each include a coil unit (1020), and the coil unit (1020) may be arranged around the driving support unit (1070). As a specific example, the coil unit (1020) may have a form wound around the driving support unit (1070).

[0109] The driving force limiting member (1090) may be placed between the first driving force providing unit (DCU1) and the second driving force providing unit (DCU2). For example, the driving force limiting member (1090) may be placed between the coil unit (1020) of the first driving force providing unit (DCU1) and the coil unit (1020) of the second driving force providing unit (DCU2).

For example, the driving force limiting member (1090) may be arranged between the coil unit (1020) of the first driving force providing unit (DCU1) and the coil unit (1020) of the second driving force providing unit (DCU2).

[0113] The coil unit (1020) of the first driving force providing unit (DCU1) and the coil unit (1020) of the second driving force providing unit (DCU2) can be placed between the driving force limiting members (1090) on both sides.

In addition, the driving force limiting member (1090) may be integrally disposed between the second driving force providing unit (DCU2) and the second driving force providing unit (DCU3), and between the third driving force providing unit (DCU3) and the fourth driving force providing unit (DCU4). In addition, the driving force limiting member (1090) may be disposed on the outer side of each of the first driving force providing unit (DCU1) and the second driving force providing unit (DCU2) disposed at the edge to reduce or prevent the diffusion of the magnetic field to the outside.

[0140] FIG. 14b is a drawing showing an exemplary plan view from one direction of the information output device of FIG. 14a.

[0141] Referring to FIG. 14b, the information output device (10000) includes a plurality of driving force providing units, for example, a first driving force providing unit (DCU1) to an eighth driving force providing unit (DCU8). For convenience of explanation, the differences from the aforementioned embodiments will be described below.

[0142] The driving force limiting member (1090) can be formed integrally to correspond to the first driving force providing unit (DCU1) to the eighth driving force providing unit (DCU8).

[0143] For example, the driving force limiting member (1090) may have a shape having at least eight openings, for example, a shape similar to a widely formed plate having eight openings, and may have a shape in which the coil units (1020) of the first driving force providing unit (DCU1) to the eighth driving force providing unit (DCU8) are fitted correspondingly to these openings.

[0144] Although not shown, the number and shape of openings formed in the driving force limiting member (1090) can be determined in various ways, and for example, more than nine openings can be formed in a wider plate shape.

[0145] The driving force limiting member (1090) is formed integrally to correspond to multiple driving force providing units, thereby improving the manufacturing convenience of the driving force limiting member (1090), and effectively reducing or preventing magnetic field interference or abnormal lateral magnetic field diffusion in the space adjacent to each driving force providing unit.

[0146]

[0147] FIG. 15 is a plan view schematically illustrating an information output device according to another embodiment of the present invention.

[0148] Referring to FIG. 15, the information output device (10000) includes a plurality of information output modules, and may include, for example, six information output modules (U11, U12, U13, U21, U22, U23) arranged in one direction (X-axis direction of FIG. 15) and one direction intersecting therewith (Y-axis direction of FIG. 15).

[0149] Additionally, although not shown, the number of information output modules arranged in one direction (X-axis direction in Fig. 15) and one direction intersecting therewith (Y-axis direction in Fig. 15) can be determined in various ways.

[0150] As an optional embodiment, six information output modules (U11, U12, U13, U21, U22, U23) may each be arranged in a base unit (BSU), and these base units (BSUs) may be formed to be distinct from each other and may be formed to be combined or separated as needed.

[0151] Each of the six information output modules (U11, U12, U13, U21, U22, U23) may include a plurality of driving force providing units, for example, eight driving force providing units (DCU1) to eighth driving force providing units (DCU8), and may include eight driving force limiting members (1090) corresponding to each of them. As a specific example, the structure of FIG. 13a or FIG. 13b may be applied.

[0152] Additionally, although not shown, the six information output modules (U11, U12, U13, U21, U22, U23) may each include eight expression units corresponding to the first driving force providing unit (DCU1) to the eighth driving force providing unit (DCU8).

[0153] Through this, each of the six information output modules (U11, U12, U13, U21, U22, U23) can selectively or simultaneously drive eight expression units to express one or more pieces of information, and by controlling the six information output modules (U11, U12, U13, U21, U22, U23) as a whole, multiple expression units can be controlled over a wide area to provide complex and diverse information to the user in a short time, and as an optional embodiment, input through the user's finger, etc. can also be detected.

[0154] In addition, although not shown, when implementing an information output device including multiple information output modules of FIG. 15, the driving force limiter of FIG. 14a or FIG. 14b described above can be applied. For example, in the case of FIG. 15, six driving force limiters of FIG. 14b can be applied.

[0155] Additionally, as an optional embodiment, the driving force limiter may be made larger and applied in two or three units, and as another example, one driving force limiter may be applied to correspond to six information output modules.

[0156] FIG. 16a is a perspective view schematically illustrating an information output device according to another embodiment of the present invention.

[0157] Referring to FIG. 16a, the information output device (20000) is similar to the aforementioned FIG. 13b, and includes eight driving force providing units, each including a coil unit (2020), and the coil units (2020) may be arranged around the driving support unit (2070). As a specific example, the coil unit (2020) may have a form wound around the driving support unit (2070).

[0158] Additionally, eight driving force limiting members (2090) may be arranged to correspond to each driving force providing member, for example, to surround the coil member (2020).

[0159] For convenience of explanation, the following description will focus on differences from the previously described embodiments. Furthermore, the structure of this embodiment can be selectively applied to the previously described embodiments and the embodiments described below, even without separate mention.

[0160] The information output device (20000) of the present embodiment may include an upper unit (1100), a lower unit (1200), and a base unit (1300).

[0161] The upper unit (1100), lower unit (1200), and base unit (1300) of the information output device (20000) of the present embodiment can be maintained in a disengaged state. This can improve the convenience of management, such as repair and replacement, of the information output device (20000).

[0162] As an optional embodiment, the upper unit (1100), the lower unit (1200), and the base unit (1300) of the information output device (20000) can be coupled and decoupled using various methods, and without inserting a separate fastening member or joining member between the respective members, the upper unit (1100), the lower unit (1200), or the base unit (1300) can be easily decoupled and separated by applying a slight pressure, for example, a force by pushing or pulling at least one area.

[0163] The upper unit (1100) can be formed to accommodate one or more expression parts (1110), and the expression parts (1110) can move upwardly and move downwardly in the opposite direction so as to protrude through an expression opening (1100TH) formed in one area of ​​the upper surface (1101) of the upper unit (1100). Through the upward and downward movements of the expression parts (1110), a user can sense the expression parts (1110), and for example, the expression surface (1111) of the expression parts (1110) can be sensed using the sense of touch, so that information interaction such as user information sensing or information input can proceed. As an optional embodiment, the sensing of the expression parts (1110) may be visual sensing.

[0164] As an optional embodiment, the upper unit (1100) may accommodate multiple expression units (1110), for example, eight expression units (1110) may be accommodated, each of which may be arranged to be distinct from the other. The eight expression units (1110) may individually or simultaneously move to output or input various pieces of information.

[0165] These eight expression parts (1110) can move by receiving driving force from each driving force providing part, and each driving force providing part includes a coil part (2020) as described above, for example, a coil part (2020) wound on a driving support part (2070), and a driving force limiting member (2090) can be arranged to reduce magnetic field interference and concentrate the direction of the magnetic field toward the expression part (1110).

[0166] Additionally, as an optional embodiment, the driving force providing units may each include a support unit (2007). The support unit (2007) may be formed to support the driving support unit (2070) and may additionally be formed to support the coil unit (2020). As an optional embodiment, a terminal unit (not shown) may be formed in one area of ​​the support unit (2007), for example, a bottom area, and arranged to be connected to the coil unit (2020).

[0167] The lower unit (1200) may be formed to be connected to the upper unit (1100). In addition, a driving force providing unit may be arranged in the lower unit (1200), for example, eight driving support units (2070) and a coil unit (2020) may be arranged, and a driving force limiting member (2090) may also be arranged. To this end, the lower unit (1200) may include an inner space in which eight driving support units (2070) and a coil unit (2020) and a driving force limiting member (2090) may be arranged.

[0168] The lower unit (1200) includes an upper surface (1201) facing the upper unit (1100), and the upper surface (1201) of the lower unit (1200) may correspond to the lower surface of the upper unit (1100). The lower surface of the upper unit (1100) may be the opposite surface of the upper surface (1101) of the upper unit (1100).

[0169] As an optional embodiment, the upper unit (1100) and the lower unit (1200) can be coupled using a groove and a corresponding extension.

[0170] For example, the upper unit (1100) has a groove (1120), and the first groove (1121) and the second groove (1122) of the groove (1120) may correspond to the first extension (1221) and the second extension (1222) of the extension (1220) of the lower unit (1200). As an optional embodiment, a step is formed in the first groove (1121) and the second groove (1122) of the groove (1120), and a catch is formed in the first extension (1221) and the second extension (1222) of the extension (1220), so that a stable bonding force can be maintained after bonding by applying force, and conversely, if a force sufficient to release the step and the catch is applied, the bonding can be easily released.

[0171] As an optional embodiment, the upper unit (1100) may include an upper protrusion (1130) formed to face the lower unit (1200), and the upper protrusion (1130) may include a first upper protrusion member (1131) and a second upper protrusion member (not shown).

[0172] The lower unit (1200) includes a lower groove corresponding to the upper protrusion (1130), and may include, as a specific example, a first lower groove (1231) and a second lower groove (1232).

[0173] The first upper protrusion member (1131) and the second upper protrusion member (not shown) may correspond to the first lower groove (1231) and the second lower groove (1232), respectively, and may have a fitting shape. At this time, the first upper protrusion member (1131) and the second upper protrusion member (not shown) may be formed to have a length smaller than the length of the first lower groove (1231) and the second lower groove (1232), and through this, the first base protrusion member (1331) and the second base protrusion member (1333) of the base protrusion (1330) of the base unit (1300) may correspond to the remaining space of the first lower groove (1231) and the second lower groove (1232).

[0174] A lower unit (1200) may be connected to the base unit (1300). For example, the lower unit (1200) may be positioned between the upper unit (1100) and the base unit (1300). As a specific example, the lower unit (1200) may be connected to the upper unit (1100) and the base unit (1300), and as an optional embodiment, the lower unit (1200) may be detachably coupled to the upper unit (1100) and the base unit (1300).

[0175] As an optional embodiment, the base unit (1300) may include a base protrusion (1330) formed to face the lower unit (1200), and the base protrusion (1330) may include a first base protrusion member (1331) and a second base protrusion member (1332).

[0176] The first base protrusion member (1331) and the second base protrusion member (1332) of the base protrusion (1330) of the base unit (1300) may correspond to the first lower groove (1231) and the second lower groove (1232) of the lower groove (1230) of the lower unit (1200). For example, they may be arranged in correspondence in a fitting form.

[0177] As an optional embodiment, the base unit (1300) includes a base extension (1340) formed to face the lower unit (1200), and a lower counterpart (1240) corresponding to the base extension (1340), for example, a first lower counterpart member (1241) and a second lower counterpart member (1242), may be formed on one surface of the lower unit (1200).

[0178] The first base extension member (1341) of the base extension portion (1340) may correspond to the first lower corresponding member (1241), and the first base extension member (1341) may have elasticity so as to spread away from the outer surface of the base unit (1300), thereby being able to firmly correspond to the first lower corresponding member (1241). Additionally, the first lower corresponding member (1241) has a groove shape and a catch area such as a step area is formed on the inner side, so that the first base extension member (1341) can be stably placed.

[0179] The base unit (1300) may have a hollow shape with a space (1300S) at least on the inside, and as an optional embodiment, may have a shape with an open top and bottom.

[0180] At least a signal connection unit (CF) may be arranged in the space unit (1300S). The signal connection unit (CF) is connected to a driving force providing unit accommodated in the lower unit (1200), and may be arranged to apply a signal to, for example, a coil unit (2020) around a driving support unit (2070).

[0181] As an optional embodiment, the signal connector (CF) may be formed to be bendable or flexible by containing a flexible material.

[0182] As an optional embodiment, the signal connection unit (CF) may be connected to a circuit control unit (CP). One or more signals may be applied to the driving force providing unit via the circuit control unit (CP).

[0183] The base unit (1300) may include one or more connecting protrusions (1363A, 1363B, 1363C) and one or more connecting grooves (1360D, 1361B, 1362B, 1363B).

[0184] The connecting protrusions (1363A, 1363B, 1363C) and connecting grooves (1360D, 1361B, 1362B, 1363B) of the base unit (1300) can be connected or combined in a corresponding form to the connecting grooves (1360D, 1361B, 1362B, 1363B) and connecting protrusions (1363A, 1363B, 1363C) of the adjacent base unit (1300).

[0185] Figure 16b is a drawing showing a modified example of Figure 16a.

[0186] Figure 16c is a drawing for explaining the driving force limiting member of 16b.

[0187] For convenience of explanation, the differences from Fig. 16a will be explained.

[0188] Referring to FIGS. 16b and 16c, the driving force limiting member (2090) can be arranged to correspond to a plurality of driving support members (2070) and coil members (2020), and for example, can be formed to correspond to eight driving support members (2070) and coil members (2020).

[0189] Through this, the driving force limiting member (2090) can be formed integrally to correspond to the eight driving support members (2070) and the coil member (2020). In addition, as an example, the driving force limiting member (2090) formed integrally to correspond to one lower unit (1200) can be arranged.

[0190] The driving force limiting member (2090) has a plate-like shape and a plurality of openings (2091), and may include, for example, eight openings (2091) corresponding to eight driving support members (2070) and coil members (2020).

[0191] As an optional embodiment, the driving force limiting member (2090) may be arranged to be connected to each other in the space between eight driving support members (2070) and coil members (2020) that are spaced apart from each other, and may also be arranged in an outer region of the eight driving support members (2070) and coil members (2020) as an example. Through this, when a plurality of information output devices are arranged, for example, when a plurality of lower units (1200) are arranged and connected, the interference of the magnetic field generated from the adjacent lower units (1200) is reduced or blocked, so that the magnetic field efficiently acts toward the expression unit in each lower unit (1200), thereby improving the driving efficiency and control characteristics.

[0192] The driving force limiting member (2090) may be positioned in the lower unit (1200) in a variety of ways, for example, it may be coupled.

[0193] As an example, it may have a form arranged on one side of the lower unit (1200), and as a specific example, it may have a form connected to the lower surface of the lower unit (1200).

[0194] In addition, as another example, it may have a form that is coupled to the inside of the lower unit (1200), and specifically, as illustrated in FIG. 16c, the driving force limiting member (2090) may be fitted into the space area (1200IU) between the bottom area (1200BU) and the top area (1200TU) of the lower unit (1200). This arrangement may be performed in various ways, and a form in which the lower unit (1200) and the driving force limiting member (2090) are coupled may be implemented by an injection molding method using a molten material. In addition, after preparing the lower unit (1200) and the driving force limiting member (2090) separately, the driving force limiting member (2090) can be fitted into the space area (1200IU) of the lower unit (1200). In this case, as an optional embodiment, the member connecting the bottom area (1200BU) and the top area (1200TU) of the lower unit (1200) can be temporarily removed or released, and then the driving force limiting member (2090) can be fitted.

[0195]

[0196] FIG. 17 is a drawing illustrating an example of driving force transmission of an information output device according to one embodiment of the present invention.

[0197] Fig. 17 illustrates a unit expression unit (IU), which may correspond to one expression unit (1110). For example, the information output device (10000) of Fig. 13a or Fig. 13b may be viewed as including eight unit output units (IU).

[0198] Each unit output unit (IU) may include a driving force providing member (DM) positioned opposite the expression unit (1110) and may be electrically connected to a control module (CM).

[0199] The driving force providing member (DM) operates on a signal from the control module (CM) to generate driving force and transmit it to the expression unit (1110), and various driving modules that cause the expression unit (1110) to perform a reciprocating motion of protrusion and retraction can be applied.

[0200] Here, the driving force providing member (DM) may include the driving force providing member and the driving force limiting member described above, and the control module (CM) may include a signal connection member (CF) or a circuit control member (CP).

[0201] FIG. 18 is a drawing illustrating another example of driving force transmission of an information output device according to one embodiment of the present invention.

[0202] Referring to FIG. 18, one embodiment of a unit output unit (IU) may include a drive unit (200), a motion unit (300), and an expression unit (1110).

[0203] The above-described driving unit (200) may include the aforementioned driving force providing unit and driving force limiting member. The driving unit (200) may generate a magnetic field when an electrical signal is applied from the control module (CM) to the aforementioned coil unit (1020). This driving unit (200) may be provided to maintain a fixed state, and for example, may be accommodated in the lower unit (1200) of the aforementioned embodiment and fixed to the lower unit (1200) even when a magnetic field is generated.

[0204] The term "electrically connected" here does not necessarily mean a wired connection, but rather includes instances where electrical signals can be transmitted via wireless communication, including instances where another transmission medium exists between the two. This can be equally applied to the embodiments of this specification.

[0205] The above movement unit (300) may be provided to move in response to the operation of the drive unit (200), more specifically, in response to a magnetic field formed by a coil unit included in the drive unit (200). To this end, the movement unit (300) may include a magnetic body or a magnet. According to one embodiment, the movement unit (300) may be provided to perform a rotational movement, and this rotational movement may consequently include a movement in a direction from the drive unit (200) toward the expression unit (1110). This movement unit (300) may move dependently on the movement of the drive unit (200), and thus may not be electrically connected to the control module (CM).

[0206] The expression unit (1110) is driven by the motion unit (300) and can move upward and downward to protrude and retract from the opening (1001TH) of the upper surface of the housing (1001) of FIG. 1 described above or the upper surface (1101) of the upper unit (1100) of FIG. 16A. According to one embodiment, the expression unit (1110) can be in contact with the motion unit (300). The expression unit (1110) may be coupled to the motion unit (300), but is not necessarily limited thereto, and a transmission medium for transmitting physical motion between the motion unit (300) and the expression unit (1110) may be included.

[0207] According to embodiments of the present invention, the present invention is not necessarily limited thereto, and at least some of the expression units (1110) may be separated from the movement unit (300). In this case, the expression units (1110) may directly contact the movement unit (300) that is moving, or may indirectly move up and down in conjunction with the movement of the movement unit (300) through a separate link mechanism (not shown) or movement transmission mechanism (not shown) with respect to the movement unit (300).

[0208] Optionally, when the position of the unit output unit is changed, such as when it is flipped over, a separate device (not shown) may be interposed between the expression unit (1110) and / or the movement unit (300) and the inner side of the upper surface (1101) of the upper unit (1100) to prevent the expression unit (1110) and / or the movement unit (300) from protruding outward from the upper surface (1101) of the upper unit (1100) when power is not supplied to the drive unit (200). This device may be an elastic member, and when the magnetic force of the drive unit (200) exceeds the elastic force of the elastic member, the expression unit (1110) may protrude outward from the upper surface (1101). This embodiment may be applied to all embodiments of the present specification.

[0209] Meanwhile, a partition wall (500) may be interposed between the drive unit (200) and the motion unit (300), and the drive unit (200) and the motion unit (300) may be provided to be physically separated from each other. As the drive unit (200) and the motion unit (300) are physically separated in this way, not only can the drive unit (200) be sealed from moisture as an optional embodiment, thereby achieving a more improved waterproof structure, but even if the motion unit (300) is in an environment where it is exposed to moisture, this environment may not affect the drive unit (200).

[0210] In the above-described embodiment, this bulkhead (500) may correspond to the lower boundary of the upper unit (1100) or the upper boundary of the lower unit (1200).

[0211] Fig. 19 is a drawing illustrating an example of the movement unit of Fig. 18. Fig. 20 is a drawing illustrating a modified example of Fig. 19.

[0212] Referring to FIG. 19, the motion unit (300) may include a body (310) that is rotatable, and the body (310) may be provided in the shape of a circular plate. However, the present invention is not necessarily limited thereto, and the body (310) may be applied in various forms that can transmit power to the pin by rotating around the rotation axis (330).

[0213] The body (310) of the movement unit (300) rotates around a rotation axis (330), and the rotation axis (330) can be positioned apart from the center of the movement unit (300), more specifically, the center (340) of the body (310). Accordingly, when the body (310) rotates around the rotation axis (330), an effect of movement in the second direction (X2) can be obtained, as in the right state of FIG. 19. As the body (310) rotates and moves in the second direction (X2), this movement is also transmitted to the expression unit (1110), so that the expression unit (1110) can also move in the second direction (X2).

[0214] The motion unit (300) may include a magnetic member (320). Optionally, the magnetic member (320) may also be positioned away from the center of the motion unit (300), specifically, the center (340) of the body (310). Accordingly, when the body (310) of the motion unit (300) rotates under the influence of the magnetic field of the coil portion of the drive unit (200), the rotation may be performed efficiently with less force.

[0215] The above magnetic member (320) can be built into the body (310), and a permanent magnet can be used. However, it is not necessarily limited thereto, and a magnetic body having an N pole (321) and an S pole (322) formed along the second direction (X2) can be used.

[0216] As in the embodiment illustrated in Fig. 19, the center of the magnetic member (320) may be located at the same position as the rotation axis (330) of the body (310). However, this is not necessarily limited to the embodiment, and as in the embodiment illustrated in Fig. 20, the center of the magnetic member (320) may be spaced apart from the rotation axis (330) of the body (310). By adjusting the positional relationship between the center of the magnetic member (320) and the rotation axis (330) of the body (310), the rotation efficiency of the body (310) can be maximized.

[0217] Meanwhile, the rotation axis (330) of the body (310) can be formed in various shapes.

[0218] Fig. 21 is a drawing illustrating a variation of the movement unit of Fig. 19. Fig. 22 is a drawing illustrating another variation of the movement unit of Fig. 19.

[0219] As can be seen in Fig. 21, the rotation axis (330) may include a first rotation axis (331). The first rotation axis (331) may be formed in a semicircular shape, and may include, for example, a straight portion (3311) extending along the second direction (X2). This straight portion (3311) may be positioned close to the center of rotation.

[0220] According to another embodiment as shown in FIG. 22, the rotation axis (330) may include a second rotation axis (332). This second rotation axis (332) may be circular.

[0221] The exercise unit (300) of the above-described embodiments may be accommodated in at least one area or in its entirety in the upper unit (1100). When the exercise unit (300) is accommodated in the upper unit (1100), a holder area corresponding to the exercise unit (300) may be formed inside the upper unit (1100). This will be described below.

[0222] Figure 23 is a drawing showing an example of a holder area of ​​an exercise unit.

[0223] Figure 24 is a drawing showing another example of a holder area of ​​an exercise unit.

[0224] Figure 25 is a drawing showing another example of a holder area of ​​an exercise unit.

[0225] The body (310) of the above exercise unit (300) can be mounted in a holder area (350) as shown in FIG. 23, and the body (310) is accommodated inside the holder area (350) and can include a support groove (351) in which a rotation axis (330) of the body (310) is supported. The holder area (350) can have sufficient space inside so that the body (310) can rotate while the rotation axis (330) is supported in the support groove (351).

[0226] The support groove (351) as described above can be formed in various shapes. According to the embodiment illustrated in FIG. 23, the support groove (351) can include a first support groove (3511) having a circular shape. Accordingly, the body can rotate while maintaining the position of the rotation shaft (330) mounted on the support groove (351) without changing.

[0227] According to another embodiment illustrated in FIG. 24, the support groove (351) may include a second support groove (3512). The second support groove (3512) may be formed in a straight line. The second support groove (3512) may extend along the second direction (X2). Accordingly, the position of the rotational shaft (330) mounted on the second support groove (3512) may move along the second direction (X2). As the position of the rotational shaft (330) moves along the second direction (X2), the body (310) rotates and the body (310) may move along the second direction (X2), which may enable the body (310) to move the expression part (1110) with only a small force. In addition, as the body (310) rotates along the second direction (X2) and moves in the direction of the expression unit (1110), the expression unit (1110) can be maintained in a fixed state even when electricity is cut off to the coil unit.

[0228] This straight line shape can be provided in various forms, and according to the embodiment illustrated in FIG. 25, the support groove (351) can include a third support groove (3513) provided in an inverted U shape. The third support groove (3513) can include a straight section (3514) and a curved section (3515). Accordingly, when the body (310) rotates, the rotation axis (330) located in the straight section (3514) can go to another straight section via the curved section (3515). Accordingly, the distance between the magnetic member and the coil can be maintained to be the same whether the expression part (1110) is raised or lowered outside the expression surface, and thus the expression part (1110) can be moved with low power.

[0229] The various embodiments of the exercise unit (300) described above can be applied in combination to all embodiments of the present specification.

[0230] Additionally, as an optional embodiment, the holder area (350) may be formed in the internal space of the upper unit (1100), for example, it may be formed integrally within the interior of the upper unit (1100).

[0231] Fig. 26 is a drawing showing an example of the drive unit of Fig. 18.

[0232] Figure 27 is a drawing showing a modified example of Figure 26.

[0233] According to the embodiment illustrated in FIG. 26, the drive unit (200) may include the drive support member (1070) and the coil member (1020) of the above-described embodiment. The drive support member (1070) may extend in the second direction (X2), and the coil member (1020) may be wound around the drive support member (1070). A drive force limiting member (1090) may be arranged around the coil member (1020).

[0234] As an electrical signal is applied to the coil unit (1020), the coil unit (1020) can form a magnetic field along the second direction (X2). This magnetic field can change the polarity of magnetism along the second direction (X2) depending on the type of electrical signal, and as the magnetic member (320) reacts to this change in the polarity of magnetism, the body (310) can rotate around the rotation axis (330).

[0235] As an optional embodiment, according to the embodiment illustrated in FIG. 26, the coil portion (1020) can be wound over the entire length of the drive support portion (1070).

[0236] However, the coil portion (1020) may be wound only on a part of the driving support portion (1070). According to another embodiment illustrated in FIG. 27, the driving unit (200) may further include a support portion (230) protruding toward the motion unit (300). The support portion (230) may be coupled to the driving support portion (1070) and extend along the second direction (X2). When the driving support portion (1070) is formed of a magnetic material, the driving support portion (1070) and the support portion (230) may be formed integrally. However, the present invention is not necessarily limited thereto, and only the driving support portion (1070) may be formed of a magnetic material, and the support portion (230) may be formed of a non-magnetic material.

[0237] According to the embodiment illustrated in FIG. 27, the body (310) may include a magnetic member receiving portion (311) in which a magnetic member (320) is received, and the magnetic member receiving portion (311) may be positioned spaced inward from an outer edge of the body (310). In addition, the support (230) may be provided so as to protrude to the inner side of the body (310) and extend to a position adjacent to the magnetic member receiving portion (311).

[0238] Figure 28 is a drawing showing one embodiment of an assembly of a drive unit and a motion unit.

[0239] Figure 29 is a schematic drawing showing another embodiment of the expression unit.

[0240] As illustrated in Fig. 28, a magnetic member receiving portion (311) is provided between a pair of bodies (310), so that even if the support (230) (or the driving support (1070)) is inserted to the inside of the body (310), the support (230) or the driving support (1070) does not interfere with the rotation of the body (310). In this case, the body (310) can sufficiently rotate in the inner space (352) of the holder area. In this way, as the support (230) (or driving support (1070)) protrudes to the inside of the body (310) and extends to a position adjacent to the magnetic member receiving portion (311), the support (230) (or driving support (1070)) supports the body (310), for example, the magnetic member receiving portion (311), when the body (310) rotates, and thus, the rotation of the body (310) can be stably performed.

[0241] As the support (230) (or the driving support (1070)) is extended, the distance between the support (230) (or the driving support (1070)) and the magnetic member (320) can be maintained close. When the support (230) (or the driving support (1070)) is formed of a magnetic material, it takes on a characteristic polarity due to the magnetic force formed by the coil unit (1020), so that even a small magnetic force can more effectively affect the magnetic member (320). Therefore, low-power driving can also be enabled. In addition, since the support (230) (or driving support (1070)) can maintain magnetism even when electricity is cut off after the coil unit (1020) is energized, the body (310) can remain fixed without being rotated in reverse again even in a state like the right side of FIG. 27, and accordingly, the expression unit (1110) can remain in a protruding state even when power is not applied. Therefore, in order to maintain the expression unit (1110) in a protruding state, it is not necessary to continuously apply electricity to the coil unit (1020). This can have the effect of reducing the operating power and / or power consumption of the entire device.

[0242] Here, as illustrated in FIG. 28, in an optional embodiment, when the upper unit (1100) and the lower unit (1200) described above are connected, the driving support member (1070) can be fixedly positioned on the lower unit (1200), and at least a part of the movement unit (300), for example, a pair of bodies (310), can move in the inner space of the upper unit (1100). The upper unit (1100) and the lower unit (1200) described and illustrated in this embodiment and the embodiments to be described later are exemplary descriptions for the convenience of explanation. That is, for the convenience of explanation, the upper unit (1100) and the lower unit (1200) of FIG. 16A of the above-described embodiment are described as an example, and the upper unit (1100) and the lower unit (1200) of FIG. 16A are not limited to the embodiments to be described here and therefore, it goes without saying that various structures of covers, housings, and receiving portions can be applied.

[0243] As can be seen in Fig. 29, the expression portion (1110) may further include a magnetic member (420). The magnetic member (420) may be formed in a plate-like or volumetric shape. In addition, although not illustrated in the drawing, the magnetic member may be coated in a film shape on the expression portion (1110) or may be mixed when forming the expression portion (1110).

[0244] Additionally, as an optional embodiment, the magnetic member (420) may have a spherical shape.

[0245] Since the expression part (1110) includes the magnetic member (420), the expression part (1110) can be prevented from protruding excessively outward from the upper surface (1101) of the upper unit (1100) even when no power is applied. When the expression part (1110) is driven inward again after protruding through an upward movement, the expression part (1110) can be driven downward more easily by the attractive force of the magnetic member (420) and the magnetic member (320) as well as the self-weight of the expression part (1110).

[0246] As an example, the magnetic member (420) may include a metal, and as a specific example, may include iron.

[0247] As an optional embodiment, it is not desirable for the magnetic force between the magnetic body member (420) and the magnetic force member (320) to be so great as to restrict the movement of the motion unit (300).

[0248] This ease of down-drive and the ability to prevent pin protrusion without power supply can enable low-power operation of the entire device. The above embodiment can be applied to all embodiments of the present invention.

[0249]

[0250] Fig. 30 is a drawing showing another embodiment of an assembly of a drive unit and a motion unit.

[0251] Fig. 31 is a schematic perspective view for explaining the movement part of Fig. 30.

[0252] Figure 32 is a front view viewed from one direction of Figure 31.

[0253] Figure 33 is a partial perspective view of Figure 30 as seen from one direction.

[0254] Referring to FIG. 30, the expression unit (2210) can move according to the movement of the movement unit (240) described later, and can move upward and downward at least based on the longitudinal direction of the expression unit (2210). For example, it can move in one direction toward the coil unit (1020) and in the opposite direction.

[0255] Through this, the expression unit (2210) can move to protrude in one direction, and the user can sense the movement of the expression unit (2210) tactilely or visually.

[0256] The expression part (2210) may include an expression surface (2211) and a support surface (2212).

[0257] The support surface (2212) is a surface of the expression portion (2210) that faces the movement portion (240), forms a lower region of the expression portion (2210), is individually arranged with the movement portion (240), and can come into contact with it at least at one point in time, and the movement portion (240) can transmit force to the expression portion (2210) through the support surface (2212).

[0258] The expression surface (2211) may include an area recognized by the user as the outermost area of ​​the expression unit (2210), for example, the area furthest from the coil unit (1020).

[0259] For example, a user may perceive the entire area of ​​the expression portion (2210), but may also perceive only the expression surface (2211). For example, a user may perceive the movement of the expression portion (2210) through contact with the expression surface (2211), and may also easily perceive the movement of the expression portion (2210) through visual detection of the expression surface (2211).

[0260] As an optional embodiment, the expression surface (2211) may include a curved surface.

[0261] The expression section (2210) can have various shapes and may include a columnar region.

[0262] Additionally, as an optional embodiment, the protruding area of ​​the expression portion (2210) may have a curved surface, and the corners may be made to have a curved surface.

[0263] The expression unit (2210) may include various materials, and may be formed of a lightweight, durable, insulating material. For example, it may contain an organic material of the resin type. As another example, it may include an inorganic material, such as a ceramic material.

[0264] Additionally, as another optional embodiment, the expression unit (2210) may be formed of a material such as metal or glass.

[0265] Additionally, these expressions (2210) may be selectively applied throughout this specification.

[0266] As described above, when a magnetic field is generated by the current flowing in the coil section (1020), a driving force is transmitted to the expression section (2210) through this, and for example, a driving force can be provided to the expression section (2210) through the movement of the movement section (240).

[0267] As an optional embodiment, one end of the driving support member (1070) may be extended to support the movement member (240), and as an optional embodiment, the movement of the movement member (240) may proceed while being supported by one end of the driving support member (1071).

[0268] As an optional embodiment, the drive support member (1070) may be connected to the drive support main body member (1072) and may have an integrated form, for example.

[0269] As an optional embodiment, a support member (280) may be further arranged and may be arranged to surround the driving support main body member (1072). As an optional embodiment, the support member (280) may include a protrusion (281) in one area, and handling may be facilitated through one area of ​​the protrusion (281). In addition, a driving force limiting member (1090) may be arranged on one area of ​​the support member (280) and may be supported by the support member (280) as an optional embodiment.

[0270] As an optional embodiment, an inner receiving area (232) may be formed in the upper unit (1100) of the above-described embodiment, which may include the holder area described above.

[0271] As an optional embodiment, a drive groove (234) may be formed in the inner receiving area (232). For example, the drive groove (234) may be formed on opposite sides of the inner surface of the inner receiving area (232), and as an optional embodiment, may have a shape extending in one direction, for example, in a direction away from the coil portion (1020).

[0272] As an optional embodiment, the driving groove (234) may be formed in a groove shape or as a through-hole area that penetrates to the outside. The driving groove (234) may be formed in a groove shape in which an area inside is removed without penetrating to the outside.

[0273] The movement unit (240) may be placed in the inner receiving area (232). The movement unit (240) may be spaced apart from the coil unit (1020) while being placed in the inner receiving area (232).

[0274] The movement unit (240) is positioned adjacent to the coil unit (1020) and can perform angular or rotational movement by being driven by a current flowing through the coil unit (1020). Through the movement of the movement unit (240), the expression unit (2210) can perform up-and-down movement, for example, movement in one direction toward the coil unit and in the opposite direction.

[0275] As an optional embodiment, a magnetic member (250) may be placed in the inner space of the moving member (240), for example. For example, the magnetic member (250) may contain a magnetic material, for example, a permanent magnet.

[0276] The magnetic part (250) may have a first region (e.g., N pole or S pole) and a second region (e.g., S pole or N pole) of different polarities, and the first region and the second region of different polarities may be arranged in a direction from the coil part (1020) toward the expression part (2210) at one point during the rotation of the movement part (240), for example, in the Z-axis direction.

[0277] For example, the first and second regions of different polarities of the magnetic part (250) can be arranged in a direction from the coil part (1020) toward the expression part (2210), for example, in the Z-axis direction.

[0278] The movement unit (240) includes a driving surface (241a) at least on the outer surface, and the driving surface (241a) is formed to support the expression unit (2210) and can provide a driving force for the up and down movement of the expression unit (2210).

[0279] As an optional embodiment, the driving surface (241a) of the movement unit (240) may include a curved surface as an outer surface. As a more specific embodiment, the driving surface (241a) of the movement unit (240) may include a boundary line having a shape similar to a circle.

[0280] The movement unit (240) may include a movement control unit (249).

[0281] The driving position of the motion unit (240) can be controlled through the motion control unit (249). For example, when the motion unit (240) moves by the coil unit (1020), it can move angularly or rotate around the motion control unit (249).

[0282] As an optional embodiment, the central axis of the movement unit (240) and the movement control unit (249) may not coincide and may be eccentric.

[0283] Additionally, as an optional embodiment, the magnetic part (250) may be positioned so as not to coincide with the central axis of the movement part (240), for example, to overlap with an area of ​​the movement control part (249).

[0284] Through this, torque force for the movement unit (240) can be easily generated, and by allowing the movement unit (240) to perform angular or rotational movements, the movement for the expression unit (2210) can be efficiently performed, and the precise expression ability of the information output device can be improved. In addition, the power consumption of the information output device can be reduced.

[0285] To explain the exercise section (240) in more detail, reference will be made to FIGS. 31 to 33.

[0286] Referring to FIGS. 31 and 32, the movement unit (240) may include a first movement member (243) and a second movement member (244), and may include a separation space (SA) therebetween.

[0287] The outer surfaces of the first moving member (243) and the second moving member (244) include a driving surface (241a) on at least one surface to support the expression member (2210) during the movement of the moving member (240) and provide driving force to the expression member (2210).

[0288] As an optional embodiment, the outer surfaces of the first moving member (243) and the second moving member (244) may include curved surfaces. For example, the first moving member (243) and the second moving member (244) may have a shape similar to a rotating body, and may each have a shape similar to a disk.

[0289] Through this, a natural driving force is provided to the support surface (2212) of the expression part (2210) during rotation or each movement of the first movement member (243) and the second movement member (244), thereby enabling the expression part (2210) to efficiently perform continuous and natural movement.

[0290] The motion control unit (249) may be disposed on at least one side of the first motion member (243) and the second motion member (244), for example, on opposite sides of the mutually facing sides of the first motion member (243) and the second motion member (244).

[0291] As an optional embodiment, the motion control unit (249) may have a protruding shape, and this protruding shape may correspond to a driving groove (234) formed in the inner receiving area (232) of the upper unit (1100).

[0292] For example, the movement unit (240) can move by the magnetic field of the coil unit (1020), and as a specific example, can move up and down due to the repulsive force and attractive force action on the magnetic unit (250) within the movement unit (240). At this time, the movement unit (240) can move up and down while rotating around the movement control unit (249), and the movement control unit (249) of the movement unit (240) can rotate while being positioned within the drive groove (234). For example, the movement control unit (249) can rotate within the drive groove (234). In addition, as an optional embodiment, the movement control unit (249) can rotate within the drive groove (234) and cause a slight up and down movement.

[0293] A first movement area (245) and a second movement area (248) can be arranged in the space (SA) between the first movement member (243) and the second movement member (244).

[0294] The first movement area (245) and the second movement area (248) may be areas that serve as reference points for the lowest and highest points during movement of the movement unit (240), respectively.

[0295] For example, when the first movement area (245) is positioned at the lowest point, that is, the area closest to the coil section (1020), the movement section (240) is positioned at the lowest point, and accordingly, the expression section (2210) is also positioned at the lowest point, specifically, when the height at which the expression section (2210) protrudes from the upper unit (1100) is the smallest.

[0296] In addition, when the second movement area (248) is positioned at the lowest part, that is, the area closest to the coil part (1020), the movement part (240) is positioned at the highest point, and accordingly, the expression part (2210) is also positioned at the highest point, specifically, when the height at which the expression part (2210) protrudes from the upper unit (1100) is the greatest.

[0297] As an optional embodiment, the first movement area (245) and the second movement area (248) may be supported by the aforementioned driving support member (1070). That is, when the movement member (240) moves, the driving support member (1070) is positioned to correspond to the space (SA) between the first movement member (243) and the second movement member (244), thereby supporting the first movement area (245) and the second movement area (248) over time.

[0298] As an optional embodiment, a connection area (247) may be arranged between the first movement area (245) and the second movement area (248), and the connection area (247) may include a curved surface.

[0299] When the movement unit (240) rotates, the driving support unit (1070) can support at least one area of ​​the connection area (247) before supporting the first movement area (245) and then the second movement area (248), thereby allowing the movement unit (240) to move naturally and the movement of the expression unit (2210) accordingly to be precisely controlled.

[0300] The distance between the driving surface (241a) and the first motion area (245) may be different from the distance between the driving surface (241a) and the second motion area (248). For example, the distance between the driving surface (241a) and the first motion area (245) may be greater than the distance between the driving surface (241a) and the second motion area (248).

[0301] As an optional embodiment, the distance from the morphological central axis of the movement unit (240) to the first movement area (245) may be smaller than the distance from the morphological central axis of the movement unit (240) to the second movement area (248).

[0302] As an optional embodiment, the distance from the motion control unit (249) to the first motion area (245) may be the same as or similar to the distance from the motion control unit (249) to the second motion area (248), and as a further optional embodiment, the distance from the motion control unit (249) to the connection area (247) may also be the same as or similar thereto.

[0303] For example, the connection area (247) may correspond to at least one area of ​​a circle having a radius centered on the center point of the motion control unit (249). Through this, when the motion unit (240) rotates around the motion control unit (249), the driving support unit (1070) supports the first motion area (245), the second motion area (248), and the connection area (247), and the position of the motion control unit (249) may be maintained identically or similarly.

[0304] In addition, the connection area (247) supported by the driving support member (1070) can include a surface close to a curved surface or an arc to efficiently perform smooth and soft movement of the moving member (240).

[0305] Referring to FIG. 33, the inner receiving area (232) of the upper unit (1100) may include a first groove (233c) and a second groove (233d). As described above, the upper unit (1100) is provided as an example for convenience of explanation and may include various forms of covers, housings, or outer walls.

[0306] The first groove (233c) and the second groove (233d) may have a deeply dug shape in the direction of the coil portion (1020). The first moving member (243) and the second moving member (244) may be arranged to correspond to the first groove (233c) and the second groove (233d), respectively, and through this, when the driving force through the coil portion (1020) is transmitted to the moving portion (240), the first moving member (243) and the second moving member (244) of the moving portion (240) may be arranged to correspond to the first groove (233c) and the second groove (233d), and the moving portion (240) may perform angular or rotational movement, and may also perform up and down movement, and through this, stable movement of the moving portion (240) is possible, and precise movement control for the expression portion (2210) may be facilitated.

[0307] As an optional embodiment, a protruding region (PT) may be formed between the first groove (233c) and the second groove (233d). For example, the protruding region (PT) may be formed to be connected to the through-hole (1250). As a specific example, the driving support member (1070) may protrude through the through-hole (1250) and reach the protruding region (PT).

[0308] In this case, as an optional embodiment, the driving support member (1070) may protrude further than the protruding region (PT), in which case the first motion region (245) and the second motion region (248) may be supported over time through the driving support member (1070). As an example, the first motion region (245) may be supported by the upper end of the driving support member (1070), specifically by contact. Through this, the state in which the expression part (2210) is at the lowest point may include being implemented by being physically latched by the upper end of the driving support member (1070). In addition, the second motion region (248) may be supported by the upper end of the driving support member (1070), specifically by contact. Through this, the expression unit (2210) may be implemented by being physically latched by the upper end of the driving support unit (1070) in a position different from the lowest point, or as an optional embodiment, in the highest point.

[0309] As an optional embodiment, the driving support (1070) may not protrude further than the protruding region (PT), in which case the protruding region (PT) may support the first motion region (245) and the second motion region (248) of the motion unit (240) over time.

[0310] For example, the first movement area (245) may be supported by the upper surface of the protruding area (PT), and the state in which the expression part (2210) is placed at the lowest point may be implemented by being physically latched by the upper surface of the protruding area (PT).

[0311] Additionally, the second movement area (248) may be supported by the upper surface of the protruding area (PT), and the state in which the expression part (2210) is placed at the highest point may be implemented by being physically latched by the upper surface of the protruding area (PT).

[0312]

[0313] Additionally, as an optional embodiment, the drive support (1070) or the protruding area (PT) may not support the motion unit (240) or may only support it temporarily, in which case the motion control unit (249) may be supported by an area of ​​the inner receiving area (232) of the upper unit (1100), for example, the boundary surface of the drive groove (234).

[0314] Figures 34 and 35 are drawings for explaining the relationship between the movement unit and the expression unit according to another embodiment of the present invention.

[0315] Referring to FIGS. 34 and 35, the movement unit (3400) and the expression unit (3110) are included. For convenience of explanation, components of the above-described embodiments, such as the coil unit, are not illustrated, but those described in the above-described embodiments can be applied by modifying them identically or similarly within an appropriate range.

[0316] The expression unit (3110) can move according to the movement of the movement unit (3400), and can move upward and downward at least based on the longitudinal direction of the expression unit (3110).

[0317] The expression unit (3110) may include an expression surface (2111) and a support surface (3112).

[0318] Additionally, although not shown, the expression unit (3110) may include a magnetic material (not shown) inside.

[0319] As an optional embodiment, the expression unit (3110) may have a space formed therein, and this space may have an open shape facing the movement unit (3400).

[0320] The movement unit (3400) can move, and can move, for example, through a magnetic field generated by a current flowing in the coil unit as described in the above-described embodiments.

[0321] Additionally, the movement unit (3400) may be supported by a protruding region (PT) during movement. Although not shown, the movement unit (3400) may also be supported by the driving support unit (1070) described in the above-described embodiment.

[0322] As an optional embodiment, the motor unit (3400) may include a drive control unit (3490), for example, one or more on a side, specifically on opposite sides.

[0323] As an optional embodiment, the motion unit (3400) can perform angular or rotational motion centered on the drive control unit (3490).

[0324] A stopper portion (3470) may be formed in one area of ​​the movement portion (3400). The stopper portion (3470) may have a shape that protrudes to have a height from the driving surface of the movement portion (3400), for example, an outer surface having a closed curve similar to a circle.

[0325] Through this, the stopper part (3470) can become a barrier to a member adjacent to the stopper part (3470) as shown in FIG. 38 and FIG. 39.

[0326] For example, as illustrated in FIG. 34, the stopper portion (3470) may serve as a barrier to the support surface (3112) of the expression portion (3110) and thus may resist continuous angular movement in one direction of the movement portion (3400), and as illustrated in FIG. 35, the stopper portion (3470) may serve as a barrier to the protruding area (PT) and thus may resist continuous angular movement in one direction of the movement portion (3400).

[0327] In addition, although not shown, during each movement of the movement section (3400), the stopper section (3470) may function as a variety of barriers while being supported by adjacent members according to design conditions.

[0328] By controlling the movement part (3400) from performing unnecessary continuous angular or rotational movements through the stopper part (3470), the shaking or vibration of the expression part (3110) can be reduced, and precise movement control of the expression part (3110) can be effectively performed.

[0329] In addition, the power required to drive the motion unit (3400) can be reduced by effectively controlling the motion unit (3400).

[0330] FIGS. 36 and 37 are perspective views illustrating optional embodiments of the driving unit of FIGS. 34 and 35.

[0331] Referring to FIGS. 36 and 37, the movement unit (3400') may include a first movement member (3443') and a second movement member (3444'), and a separation space may be formed between them.

[0332] The outer surfaces of the first moving member (3443') and the second moving member (3444') include a driving surface (3411a') on at least one surface to support the expression member (3110) during the movement of the moving member (3400') and provide driving force to the expression member (3110).

[0333] As an optional embodiment, the outer surfaces of the first moving member (3443') and the second moving member (3444') may include curved surfaces. For example, the first moving member (3443') and the second moving member (3444') may have a shape similar to a rotating body, and each may have a shape similar to a disk.

[0334] The drive control unit (3490') may be disposed on at least one side of the first moving member (3443') and the second moving member (3444'), for example, on opposite sides of the facing sides of the first moving member (3443') and the second moving member (3444').

[0335] A first motion area (3445') and a second motion area (3448') can be arranged in a space (SA) between the first motion element (3443') and the second motion element (3444').

[0336] As an optional embodiment, the rising and falling of the expression part (3110) during the movement of the movement part (3400') can be performed through the first movement area (3445') and the second movement area (3448').

[0337] For example, the first movement area (3445') and the second movement area (3448') may be areas that serve as references for the lowest and highest points of the expression unit (3110).

[0338] As an optional embodiment, the first motion area (3445') and the second motion area (3448') may be supported by a protruding area (PT), and as another example, may be supported by the driving support (1070) mentioned in the above-described embodiment.

[0339] As an optional embodiment, a connecting region (3447') may be positioned between the first movement region (3445') and the second movement region (3448'), and the connecting region (3447') may include a curved surface.

[0340] As an optional embodiment, although not shown, a magnetic member (not shown) may be arranged in the moving member (3400'), for example, in the inner space (3450M') of the moving member (3400'). For example, the magnetic member (not shown) may contain a magnetic material, for example, may include a permanent magnet. A stopper member (3470') may be formed in one area of ​​the moving member (3400'). For example, the stopper member (3470') may have a protruding shape so as to have at least a height from the driving surface (3411a'). As a specific example, at least one area of ​​the stopper member (3470') may have a protruding shape so as to have a height equal to the outer surfaces of the first moving member (3443') and the second moving member (3444').

[0341] As an optional embodiment, the stopper portion (3470') may be formed adjacent to the outer surfaces of the first moving member (3443') and the second moving member (3444'), and may be connected to, for example, the second moving area (3448').

[0342] As an optional embodiment, the stopper portion (3470') may have a height based on the outer surfaces of the first moving member (3443') and the second moving member (3444') and may include areas having different heights.

[0343] For example, the height of an area far from the second movement area (3448') among the areas of the stopper portion (3470') may be greater than the height of an area connected to the second movement area (3448').

[0344] Through this form, the stopper part (3470') can perform an effective resistance function during each movement of the movement part (3400').

[0345] In each movement of the movement unit (3400') of the present embodiment, force is applied only until the movement unit (3400') reaches a critical point, and from that point onward, each movement can be performed additionally without applying a separate force.

[0346] Through this, current can be applied to the coil and power can be consumed only during a portion of the entire operation time of the movement process of the motor (3400').

[0347] As an optional embodiment, when current is applied to the coil section only in the initial stage including the start stage of the movement of the movement section (3400') and the movement section (3400') starts to move, the movement section (3400') can easily perform each movement by the torque force through the eccentricity.

[0348] In addition, as an example, one area of ​​the movement unit (3400') may be supported by the upper or protruding area of ​​the driving support unit, for example, by contact, and the state in which the expression unit is placed at the lowest point may be implemented by being physically latched.

[0349] Additionally, as a specific example, another area of ​​the movement unit (3400') may be supported, for example by contact, by the driving support or the protruding area, thereby allowing the expression unit to be placed at a position different from the lowest point, or as an optional embodiment, at the highest point, and this state may include being implemented by being physically latched by the driving support or the protruding area.

[0350] Figure 38 is a cross-sectional view schematically illustrating an information output device according to another embodiment of the present invention.

[0351] Referring to FIG. 38, the information output device according to the present embodiment may include the expression unit (1110), the driving force providing unit (200), and the movement unit (300) of the above-described embodiments, or may use them in a modified form.

[0352] Accordingly, in the following, differences from the above-described embodiments will be mainly explained, and contents that are the same as the above-described embodiments or that can be easily modified by a person having ordinary knowledge in the technical field to which the present invention belongs from the above-described embodiments will be briefly explained or omitted.

[0353] The expression unit (1110) can move in at least one direction so that the user can sense it. Specifically, the expression unit (1110) can move in a second direction (X2), and by this movement, the user can sense the expression unit (1110) tactilely.

[0354] The driving force providing unit (200) may include the driving force providing units (200) of the above-described embodiments, and may include the driving force providing unit (200) described with reference to FIG. 26, FIG. 27, etc. as a specific example.

[0355] The driving force providing unit (200) may include a driving support unit (1070) and a coil unit (1020). The driving support unit (1070) may be formed to extend in the second direction (X2), and the coil unit (1020) may be wound around the driving support unit (1070). A driving force limiting member (1090) may be arranged around the coil unit (1020).

[0356] As an electrical signal is applied to the coil unit (1020), the coil unit (1020) can form a magnetic field along the second direction (X2). This magnetic field can change the polarity of magnetism along the second direction (X2) depending on the type of electrical signal, and as the magnetic member (320) reacts to this change in the polarity of magnetism, the body (310) can rotate around the rotation axis (330).

[0357] The coil portion (1020) may be wound around at least a portion of the drive support portion (1070). For example, the coil portion (1020) may be wound over the entire length of the drive support portion (1070), or as another example, the coil portion (1020) may be wound around only a portion of the drive support portion (1070).

[0358] The driving force providing unit (200) may further include a support (230) protruding toward the motion unit (300). The support (230) may be coupled to the driving support (1070) and extend along the second direction (X2). If the driving support (1070) is formed of a magnetic material, the driving support (1070) and the support (230) may be formed integrally. However, the present invention is not necessarily limited thereto, and only the driving support (1070) may be formed of a magnetic material, and the support (230) may be formed of a non-magnetic material.

[0359] The motion unit (300) may be positioned on one side of the expression unit (1110) and may be formed to be rotatable in at least one direction. The motion unit (300) may rotate the expression unit (1110) in at least one direction while at least one portion thereof rotates.

[0360] Specifically, the movement unit (300) can be formed to be rotatable in at least one direction by a magnetic field formed by the coil unit (1020) when an electric field is applied to the coil unit (1020).

[0361] The movement unit (300) may include a body (310), and the body (310) may include a magnetic member receiving portion (311) in which a magnetic member (320) is received. Accordingly, the body (310) may rotate in at least one direction when a magnetic field is formed by the coil portion (1020), thereby moving the expression portion (1110) disposed on one side of the movement unit (300).

[0362] The information output device illustrated in Fig. 38 may further include a driving force limiting member (1090). The driving force limiting member (1090) may be formed to reduce or limit the transmission of driving force generated from the driving force providing unit (200) in a direction other than the direction from the driving force providing unit (200) toward the expression unit (1110).

[0363] Specifically, the driving force limiting member (1090) can reduce or prevent the magnetic field generated through the coil unit (1020) from interfering with an adjacent space or from interfering with an adjacent space. In addition, the driving force limiting member (1090) can reduce or prevent the magnetic member (320) included in the motion unit (300) from interacting with the coil unit (1020) or other adjacent magnetic members.

[0364] For example, the driving force limiting member (1090) can reduce or shield interference of a magnetic field in a direction away from the side of the coil section (1020) (X-axis direction in the drawing), and can precisely control the movement of the expression section and improve the efficiency of the movement by strengthening the directionality of the magnetic field toward the expression section.

[0365] In addition, in other words, the driving force providing unit (200) utilizes a magnetic field generated from the coil unit (1020), and the motion unit (300) includes a magnetic member (320) that has magnetism, so as to reduce or block the transmission of the magnetic field to the adjacent side space, and effectively allow the force of the magnetic field to reach the expression unit (1110) from the coil unit (1020).

[0366] The driving force limiting member (1090) may be arranged on at least one side of the driving force providing member (200). For example, the driving force limiting member (1090) may be arranged on one outer side of the coil unit (1020), and specifically, may be arranged to overlap at least a portion of the coil unit (1020).

[0367] As an optional embodiment, the driving force limiting member (1090) may be formed to have a height that at least partially overlaps the motion unit (300). Referring again to FIG. 38, it can be seen that the driving force limiting member (1090) is positioned on the outside of the motion unit (300).

[0368] In a preferred embodiment, the driving force limiting member (1090) may be formed to extend to a position corresponding to the uppermost end of the motion unit (300). In other words, the driving force limiting member (1090) may be formed to extend from the coil portion (1020) to cover the entire motion unit (300).

[0369] The driving force limiting member (1090) may be arranged on both sides of the outer side of the coil portion (1020) and the motion unit (300), and as another example, the driving force limiting member (1090) may be arranged to surround at least one area of ​​the outer side of the coil portion (1020) and the motion unit (300).

[0370] The driving force limiting member (1090) can be formed of various materials and may contain, for example, a metal material.

[0371] The driving force limiting member (1090) may be formed of a material that affects the magnetic field generated from the coil section (1020), and may contain, for example, a magnetic material. As a specific example, it may contain iron, nickel, cobalt, and various other magnetic materials.

[0372] Figure 39 is a cross-sectional view schematically illustrating an information output device according to another embodiment of the present invention.

[0373] Referring to FIG. 39, the information output device according to the present embodiment may include a plurality of driving force providing units (200) and a plurality of movement units (300).

[0374] Meanwhile, an expression unit (1110) may be placed on each side of a plurality of movement units (300).

[0375] Each driving force providing unit (200) may include a coil unit (1020), and the coil unit (1020) may be arranged around the driving support unit (1070). As a specific example, the coil unit (1020) may have a form wound around the driving support unit (1070).

[0376] The driving force limiting member (1090) may be placed between the driving force providing units (200) and the movement units (300). For example, the driving force limiting member (1090) may be placed between the driving force providing unit (200) and the movement unit (300) on the left side and the driving force providing unit (200) and the movement unit (300) on the right side with reference to FIG. 39.

[0377] Accordingly, the driving force limiting member (1090) can function to prevent a plurality of driving force providing units (200) and motion units (300) from interfering with or interacting with each other when they are arranged adjacent to each other.

[0378] In addition, in this case, the driving force limiting member (1090) may be formed to have a length, and specifically, may be arranged to overlap at least a portion of the coil portion (1020) and a portion of the motion unit (300). Preferably, the driving force limiting member (1090) may be formed to extend from a position corresponding to the lowest end of the coil portion (1020) to a position corresponding to the highest end of the motion unit (300).

[0379] Figure 40 is a cross-sectional view schematically illustrating an information output device according to another embodiment of the present invention.

[0380] Referring to FIG. 40, the information output device according to the present embodiment may include a plurality of driving force providing units (200) and a plurality of movement units (300).

[0381] Meanwhile, an expression unit (1110) may be placed on each side of a plurality of movement units (300).

[0382] Each driving force providing unit (200) may include a coil unit (1020), and the coil unit (1020) may be arranged around the driving support unit (1070). As a specific example, the coil unit (1020) may have a form wound around the driving support unit (1070).

[0383] The driving force limiting member (1090) may be placed on the outside of each driving force providing unit (200) and movement unit (300). In other words, each driving force providing unit (200) and movement unit (300) may be formed so that the driving force limiting member (1090) is surrounded on the outside.

[0384] Accordingly, the driving force limiting member (1090) can function to prevent a plurality of driving force providing units (200) and motion units (300) from interfering with or interacting with each other when they are arranged adjacent to each other.

[0385] In addition, in this case, the driving force limiting member (1090) may be formed to have a length, and specifically, may be arranged to overlap at least a portion of the coil portion (1020) and a portion of the motion unit (300). Preferably, the driving force limiting member (1090) may be formed to extend from a position corresponding to the lowest end of the coil portion (1020) to a position corresponding to the highest end of the motion unit (300).

[0386] FIG. 41 is a perspective view illustrating an information output device according to one embodiment of the present invention, and FIG. 42 is a cross-sectional view illustrating an information output device according to the embodiment of FIG. 41.

[0387] Referring to FIGS. 41 and 42,

[0388]

[0389]

[0390] An information output device (100) according to one embodiment of the present invention may include a driving unit (110), an expression unit (120), a base unit (130), a first driving unit (140), a second driving unit (150), and a support unit (160).

[0391] According to one embodiment of the present invention, the driving source (110) is connected to a power source (P) and arranged to allow current to flow, and may be formed as a coil. Since it is formed as a coil, when current flows, a magnetic field may be formed around the driving source (110).

[0392] The driving unit (110) can have various shapes, can have a shape in which multiple circuit wires are wound, and can be formed by varying the number of windings, etc. The first driving unit (140) and the second driving unit (150), which will be described later, can be driven through a magnetic field generated by the current flowing in the driving unit (110).

[0393] In addition, as the first driving unit (140) and the second driving unit (150) are driven, the driving force for the movement of the expression unit (120) that is in direct or indirect contact with them can be provided.

[0394] A support member (160), which will be described later, may be placed on the inside of the driving unit (110) according to one embodiment of the present invention.

[0395] According to one embodiment of the present invention, the support member (160) may include a region that is formed to be elongated and may be arranged to penetrate the driving unit (110). As a specific example, the driving unit (110) formed as a coil may be formed to have a shape in which the driving unit (110) is wound multiple times around the region that is formed to be elongated in the support member (160).

[0396] Although not shown in the drawing, one end of the support member (160) can be extended to support the first driving member (140), and the movement of the first driving member (140) can proceed while being supported by one end of the support member (160).

[0397] The support member (160) corresponds to the passage hole (131h) formed in the first receiving member (131), and can be positioned to penetrate the passage hole (131h).

[0398] The support member (160) according to one embodiment of the present invention may include a magnetic material, thereby increasing the size of the magnetic field when a magnetic field is generated through the driving source member (110), and efficiently generating the magnetic field, thereby reducing the power consumption of the information output device (100) and increasing the driving force.

[0399] The expression unit (120) according to one embodiment of the present invention is formed and arranged to be sensed by the user (H), and can move according to the movement of the first driving unit (140) and the second driving unit (150) to be described later, and can move upward or downward (based on FIG. 42) at least with respect to the longitudinal central axis of the expression unit (120).

[0400] The expression unit (120) can move in the first direction (lower side as shown in FIG. 42) to approach the driving unit (110), or can move in the opposite direction to the first direction (upper side as shown in FIG. 42) to move away from the driving unit (110).

[0401] The expression part (120) can be exposed to the outside through an inlet hole (133h) formed in the second receiving part (133) to be described later. Since the expression part (120) is exposed to the outside, the user (H) can sense the movement of the expression part (120) tactilely or visually.

[0402] The expression part (120) according to one embodiment of the present invention may include an expression surface (121), a support surface (122), and a periphery (123).

[0403] The expression surface (121) according to one embodiment of the present invention may include an area recognized by the user (H) as the outermost area of ​​the expression unit (120), specifically, the area furthest from the driving unit (110).

[0404] The user (H) can recognize the expression unit (120) through the entire area of ​​the expression unit (120), but can also recognize only the expression surface (121). For example, the user (H) can detect the movement of the expression unit (120) through contact with the expression surface (121), and the user (H) can easily detect the movement of the expression unit (120) through visual detection of the expression surface (121).

[0405] The expression surface (121) according to one embodiment of the present invention is formed to be convex toward the outside and may include a curved surface. However, it is not limited thereto and may include a columnar region, for example, may include a region having a shape similar to a cylinder.

[0406] According to one embodiment of the present invention, the expression surface (121) can be formed with a flat upper surface (based on FIG. 42), and various deformations can be performed, such as forming only the corner portions with a predetermined radius of curvature.

[0407] The support surface (122) is a surface of the expression section (120) facing the second driving section (150), forming a lower area of ​​the expression section (120), and can come into contact with the second driving section (150).

[0408] The second driving unit (150) can transmit force to the expression unit (120) through the support surface (122). Specifically, when the second driving body (151) is in contact with the support surface (122), the support surface (122) is moved in the first direction (upper side as shown in FIG. 42), and the expression surface (121) is exposed to the outside so that the user (H) can recognize it.

[0409] According to one embodiment of the present invention, the peripheral portion (123) is connected to the support surface (122), and can be formed so that the length from the longitudinal central axis of the expression portion (120) is relatively the largest.

[0410] Specifically, the outer diameter of the circumference (123) can be formed to be larger than the inner diameter of the inlet hole (133h) formed in the second receiving portion (133). This has the effect of preventing the expression portion (120) disposed on the inner side of the second receiving portion (133), specifically the circumference (123), from passing through the inlet hole (133h) and escaping to the outside.

[0411] The expression unit (120) according to one embodiment of the present invention can be formed from various materials, and may be formed from an insulating material that is lightweight and durable. Specifically, it may contain an organic material of the resin series, or an inorganic material such as a ceramic material.

[0412] However, it is not limited to this, and the expression part (120) can be formed of a material such as metal or glass, and various modifications are possible.

[0413] According to one embodiment of the present invention, the base portion (130) accommodates the driving source portion (110) and the expression portion (120), and may include a first receiving portion (131), a second receiving portion (133), and a third receiving portion (135).

[0414] The base portion (130) according to one embodiment of the present invention may have a long, extended shape to accommodate the driving source portion (110), the first driving portion (140), and the second driving portion (150), and may be formed to entirely surround the driving source portion (110), the first driving portion (140), and the second driving portion (150).

[0415] According to one embodiment of the present invention, the first receiving portion (131) receives the driving source portion (110) and the first driving portion (140), and the driving source portion (110) and the support portion (160) can be arranged on one side (lower side as of FIG. 42) of the first receiving portion (131).

[0416] According to one embodiment of the present invention, a layer (not shown in the drawing) in which a passage hole (131h) is formed is arranged at a preset height of the first receiving portion (131), and a driving source portion (110) and a support portion (160) can be arranged in a space formed by the layer portion and the inner wall (131a) of the first receiving portion (131).

[0417] A catch groove can be formed on the upper side based on the layer formed in the first receiving portion (131), and the first driving portion (140) can be hung thereon, and the first driving portion (140) can perform angular or rotational movements.

[0418] According to one embodiment of the present invention, the second receiving portion (133) is arranged to face the first receiving portion (131) and receives the expression portion (120). A passage hole (133h) may be formed on one surface facing the expression portion (121) so that the expression portion (120), specifically the expression surface (121), protrudes and passes through and is exposed to the outside.

[0419] According to one embodiment of the present invention, the first receiving portion (131) and the second receiving portion (133) may be arranged adjacent to each other and may be arranged so as not to overlap each other.

[0420] According to one embodiment of the present invention, a third receiving portion (135) may be arranged between the first receiving portion (131) and the second receiving portion (133), and preset areas of the first driving portion (140) and the second driving portion (150) may be arranged in the third receiving portion (135).

[0421] The third receiving portion (135) covers a pair of engaging grooves (131b) formed facing the first receiving portion (131), and can prevent the first driving portion (140) that is seated in the engaging grooves (131b) from coming off.

[0422] A groove is formed at the lower end of the second receiving portion (133) (based on FIG. 42), the second receiving portion (133) covers the third receiving portion (135), and when positioned on the upper side of the third receiving portion (135), the second driving portion (150) is rotatably seated in the groove. Since the second receiving portion (133) and the third receiving portion (135) are coupled, the second driving portion (150) can be prevented from being detached.

[0423] In addition, the longitudinal central axis of the second driving unit (150) is maintained by connecting the second receiving unit (133) and the third receiving unit (135), and the longitudinal central axis of the first driving unit (140) can be maintained by connecting the second receiving unit (133) and the first receiving unit (131).

[0424] According to one embodiment of the present invention, the third receiving portion (135) may be connected to the second receiving portion (133) on one side (upper side as shown in FIG. 41) and may be connected to the first receiving portion (131) on the opposite side (lower side as shown in FIG. 41).

[0425] In a third receiving portion (135) according to one embodiment of the present invention, a second driving portion (150) to be described later may be arranged, and a driving support (136) and a driving groove portion (137) may be provided.

[0426] The third receiving portion (135) can be opened at the top and bottom, and a driving groove (137) is formed. The driving support member (136) connects the facing inner walls (131a) of the third receiving portion (135) that are opened, and the driving support member (136) can be formed integrally with the third receiving portion (135).

[0427] The rotation center of the second driving unit (150), specifically the second driving body (151), is formed at a point that deviates from the center of the second driving body (151), and since the rotation center of the second driving body (151) is eccentric, as the first movement area (152), the second movement area (153), and the connection area (154) where the second magnetic unit (155) to be described later is fixed in position rotate, the second driving unit (151) comes into contact with the expression unit (120), and there is an effect of being able to move the expression unit (120) in the first direction (upper side as shown in FIG. 42).

[0428] According to one embodiment of the present invention, the first driving unit (140) is disposed inside the base unit (130), specifically the first receiving unit (131) and the third receiving unit (135), and may include a first driving body (141), a magnet holder (144), a first magnetic unit (145), and a first driving control unit (149).

[0429] The first driving unit (140) may be spaced apart from the driving source unit (110) disposed in the first receiving unit (131). The first driving unit (140) may be disposed adjacent to the driving source unit (110) and may be driven by the current flowing in the driving source unit (110) to perform angular or rotational motion.

[0430] The movement of the first driving unit (140) can be transmitted to the second driving unit (150), and when the second driving unit (150) receives power from the first driving unit (140) and performs angular or rotational movement, the expression unit (120) is raised or lowered to move in the first direction (lower side in FIG. 8) toward the driving source unit (110) and in the opposite direction.

[0431] The first driving unit (140) may have a first driving control unit protrudingly formed on both sides. The first driving unit (140) may perform angular or rotational movement around the first driving control unit.

[0432] As an optional embodiment, the central axis of the first drive unit (140) and the first drive control unit may not coincide and may be eccentric.

[0433] As an optional embodiment, the first drive control unit may not be formed in a protruding shape, and the first drive body (141) may be formed in a spherical shape.

[0434] According to one embodiment of the present invention, the first driving body (141) is provided with a flat portion (143) and a curved portion (142), and since the flat portion (143) is formed in a preset section, the polarity formed in the first magnetic portion (145) can be correctly arranged in the up-down direction (based on FIG. 8).

[0435] According to one embodiment of the present invention, a first driving unit (140) is provided with a pair of first driving bodies (141) based on the central portion, and a magnet holder (144) is positioned between the pair of first driving bodies (141), and a first magnetic unit (145) can be accommodated in the magnet holder (144).

[0436] The first magnetic member (145) according to one embodiment of the present invention may contain a magnetic material, for example, a permanent magnet. The first magnetic member (145) may be formed to have a relatively greater magnetic force than the second magnetic member (155) provided in the second driving member (150) to be described later.

[0437] As a result, when an external force applied by a user (H) is applied to the expression unit (120), and the second driving unit (150) cannot rotate, after the external force applied to the expression unit (120) is removed, the second magnetic unit (155) and the second driving unit (150) where the second magnetic unit (155) is arranged are rotated by the magnetic force of the first magnetic unit (145), and the expression unit (120) can be moved in the first direction and the opposite direction.

[0438] That is, even if power (P) provided for only a relatively short time due to an external force applied to the expression unit (120) cannot be transmitted to the second drive unit (150) via the first drive unit (140), the first drive unit (140) performs an angular movement or rotational movement in a direction preset by the power transmitted from the drive source unit (110), and when the external force applied to the expression unit (120) is removed, there is an effect in which the second drive unit (150) can perform an angular movement or rotational movement by the first drive unit (140).

[0439] According to one embodiment of the present invention, the first magnetic portion (145) may have a first magnetic region (N pole or S pole) and a second magnetic region (S pole or N pole) of different polarities, and the first magnetic region (145a) and the second magnetic region (145b) of different polarities may be arranged in a direction from the driving source portion (110) toward the expression portion (120) at one point during the rotation of the first driving portion (140), for example, in the direction of the Z axis (based on FIG. 41).

[0440] According to one embodiment of the present invention, the second driving unit (150) is arranged between the first driving unit (140) and the expression unit (120), and can be formed to perform angular or rotational movement according to the driving of the first driving unit (140) and to move the expression unit (120) in a first direction (lower side as shown in FIG. 42) toward the first driving unit (140) and in the opposite direction (upper side as shown in FIG. 42).

[0441] A second driving unit (150) according to one embodiment of the present invention may include a second driving body (151), and one side of the second driving body (151) may be formed to support the expression unit (120) to provide driving force for the up and down movement of the expression unit (120).

[0442] One side of the second driving body (151) according to one embodiment of the present invention may include a curved surface, and as a more specific embodiment, may include a boundary line having a shape similar to a circle.

[0443] As a result, as the second driving unit (150) and the second driving body (151) move, the outer surface of the second driving unit (151) transmits power to the expression unit (120), specifically, the support surface (122), and the expression unit (120) can move in the first direction (lower side as shown in FIG. 42) toward the first driving unit (140) and in the opposite direction (upper side as shown in FIG. 42).

[0444] The second driving body (151) according to one embodiment of the present invention may have a shape similar to a rotating body, and may be modified in various ways, such as having a shape similar to a disk.

[0445] Due to this, a natural driving force is provided to the support surface (122) of the expression part (120) during each movement or rotational movement of the second driving body (151), thereby enabling the expression part (120) to efficiently perform continuous and natural movement.

[0446] According to one embodiment of the present invention, a connecting portion is connected to a first driving body (141), and a second magnetic portion (155) can be accommodated therein.

[0447] A second driving unit (150) according to one embodiment of the present invention may include a pair of second driving bodies (151), a separation space (SA) is formed between the pair of second driving bodies (151), and a connecting part (drawing symbol not set) may be arranged in the separation space.

[0448] According to one embodiment of the present invention, a connecting portion may accommodate a second magnetic member (155). The second magnetic member (155) may contain a magnetic material, for example, a permanent magnet. The second magnetic member (155) may be formed to have a relatively lower magnetic force than the first magnetic member (145).

[0449] As a result, a change in the magnetic field formed in the second magnetic part (155) occurs due to the magnetic force of the first magnetic part (145), and the second driving part (150) in which the second magnetic part (155) is received can move, but a change in the magnetic field formed in the first magnetic part (145) due to the magnetic force of the second magnetic part (155) can be prevented.

[0450] In other words, when an external force applied by a user (H) is applied to the expression unit (120), and the second driving unit (150) cannot rotate, after the external force applied to the expression unit (120) is removed, the second magnetic unit (155) and the second driving unit (150) where the second magnetic unit (155) is arranged are rotated by the magnetic force of the first magnetic unit (145), and the expression unit (120) can be moved in the first direction and the opposite direction.

[0451] That is, even if power (P) provided for only a relatively short time due to an external force applied to the expression unit (120) cannot be transmitted to the second drive unit (150) via the first drive unit (140), the first drive unit (140) performs an angular movement or rotational movement in a direction preset by the power transmitted from the drive source unit (110), and when the external force applied to the expression unit (120) is removed, there is an effect in which the second drive unit (150) can perform an angular movement or rotational movement by the first drive unit (140).

[0452] The second magnetic portion (155) according to one embodiment of the present invention may have a first magnetic region (N pole or S pole) and a second magnetic region (S pole or N pole) of different polarities, respectively, and the first magnetic region and the second magnetic region of different polarities may be arranged in a direction from the driving source portion (110) toward the expression portion (120) at one point during the rotation of the first driving portion (140), for example, in the direction of the Z axis (based on FIG. 41).

[0453] According to one embodiment of the present invention, the second magnetic force unit (155) may be arranged so as not to coincide with the central axis of the second driving unit (150), specifically the second driving body (151), and, for example, to overlap with a region of the second driving control unit (159).

[0454] This makes it possible to easily generate torque for the second driving unit (150), and to efficiently perform movement for the expression unit (120) by allowing the second driving unit (150) to perform angular or rotational movement, thereby improving the precise expression ability of the information output device (100).

[0455] In addition, since torque for the second driving unit (150) is easily generated, there is an effect of reducing the power consumption of the information output device (100).

[0456] According to one embodiment of the present invention, the second driving unit (150) may be driven by receiving power from the first driving unit (140) that receives power from the driving source unit (110). Specifically, the second driving unit (150) may move by the magnetic field generated by the first driving unit (140).

[0457] That is, it can move due to the repulsive and attractive forces acting on the second driving unit (150), specifically the second magnetic unit (155) accommodated in the connecting unit. The first driving unit (140), specifically the first magnetic unit (145) accommodated in the magnet holder (144), moves due to the magnetic field of the driving source unit (110), and as the first magnetic unit (145) moves, the second magnetic unit (155) of the second driving unit (150) can rotate.

[0458] According to one embodiment of the present invention, a support part (160) may be arranged on the inside of the driving source part (110).

[0459] According to one embodiment of the present invention, the support member (160) may include a region that is formed to be elongated and may be arranged to penetrate the driving unit (110). As a specific example, the driving unit (110) formed as a coil may be formed to have a shape in which the driving unit (110) is wound multiple times around the region that is formed to be elongated in the support member (160).

[0460] The support member (160) corresponds to the passage hole (131h) formed in the first receiving member (131), and can be positioned to penetrate the passage hole (131h).

[0461] The support member (160) according to one embodiment of the present invention may include a magnetic material, thereby increasing the size of the magnetic field when a magnetic field is generated through the driving source member (110), and efficiently generating the magnetic field to reduce power consumption of the information output device (100) and increase driving force.

[0462] The operating principle and effect of the information output device (100) according to one embodiment of the present invention as described above will be described.

[0463] An information output device (100) according to one embodiment of the present invention may include a driving unit (110), an expression unit (120), a base unit (130), a first driving unit (140), a second driving unit (150), and a support unit (160).

[0464] According to one embodiment of the present invention, the driving source (110) may be formed as a coil, and when current is applied from a power source (P), a magnetic field may be formed. A repulsive or attractive force may be applied to the first driving source (140) by the magnetic field formed in the driving source (110).

[0465] This illustrates the fixed position state of the information output device (100). When current is applied to the driving source (110), a magnetic field is formed, and when a repulsive force is applied to the first magnetic force (145), specifically, the first magnetic force (145a), the first magnetic force (145a) tries to move to a position farther away from the driving source (110), and the second magnetic force (145b) moves to a position closer to the driving source (110) by an attractive force.

[0466] The first driving part (140) in which the first magnetic part (145) is received moves due to the movement of the first magnetic part (145).

[0467] The first driving part (140), specifically the first driving body (141), has a curved part (142) and a flat part (143) formed along the outer circumference thereof, and the rotation of the first driving part (140) is stably enabled by the curved part (142), and when the position of the first magnetic part (145) accommodated in the magnet holder (144) moves to the final position as the first magnetic region (145a) and the second magnetic region (145b) move, the flat part (143) makes surface contact with one surface of the first receiving part (131) facing it, and there is an effect of stably maintaining the position.

[0468] After the movement of the first driving unit (140) is completed, the first driving unit (140) transmits power to the second driving unit (150) to cause the second driving unit (150) to move angularly or rotate. The second driving unit (150) according to one embodiment of the present invention receives power from the first driving unit (140) to move, and can move by repulsive force or attractive force with respect to the first driving unit (140).

[0469] When the first magnetic region (145a) of the first driving unit (140), specifically the first magnetic region (145) accommodated in the magnet holder (144) by receiving power from the driving unit (110), is placed above the second magnetic region (145b), the second driving unit (150), specifically the second magnetic region (155b) of the second magnetic region (155) on which the first magnetic region (145a) and the second driving unit (150) exert an attractive force, is moved to be placed close to the first driving unit (140).

[0470] The second driving unit (150) moves around the second driving control unit (159) as a center of rotation due to the movement of the second magnetic force unit (155), and at this time, the second movement area (153) moves to a position close to the first driving unit (140) and can be supported by the driving support (136) formed in the third receiving unit (135).

[0471] As the distance from the center of rotation to the second movement area (153) of the second driving body (151) is formed to be greater than the distance from the center of rotation to the first movement area (152), when the first movement area (152) is directed toward the expression part (120), specifically, the support surface (122), the second driving body (151) can push by supporting the support surface (122) of the expression part (120) upward (based on FIG. 8).

[0472] That is, the first driving part (140) and the second driving part (150) do not directly contact and support each other, but are placed in separate first receiving parts (131) and third receiving parts (135), respectively, so that movement is possible by the magnetic field of the driving source part (110) without being affected by an external force, and when the external force is removed, the position of the second magnetic part (155) changes by a repulsive or attractive force by the first magnetic part (145) of the first driving part (140) whose position has already been determined, and as the second driving part (1500) moves, the expression part (120) can be moved up and down.

[0473] As an example, the information output device (100) according to the present embodiment may further include a driving force limiting member (3090).

[0474] The driving force limiting member (3090) can play a role in reducing or preventing the magnetic field of the driving source (110) from interfering with or interacting with other external elements.

[0475] For example, the driving force limiting member (1090) can reduce or shield the interference of the magnetic field in the direction away from the side of the driving source (110) (X-axis direction in the drawing), and can precisely control the movement of the expression unit and improve the efficiency of the movement by strengthening the directionality of the magnetic field toward the expression unit.

[0476] In addition, in other words, the information output device (100) utilizes a magnetic field generated from a driving source (110), and the first driving source (140) and the second driving source (150) also include a first magnetic force portion (145) and a second magnetic force portion (155) that are magnetic, so that the transmission of the magnetic field to an adjacent side space can be reduced or blocked, and the force of the magnetic field can be effectively directed based on the direction from the driving source (110) toward the expression portion (1110).

[0477] The driving force limiting member (3090) may be arranged on at least one side of the driving source portion. For example, the driving force limiting member (1090) may be arranged on one outer side of the coil portion (1020), and specifically, may be arranged to overlap at least a portion of the coil portion (1020).

[0478] Regarding the arrangement of the driving force limiting member (3090), it may be the same as the above-described embodiments or may be easily modified and adopted from the above-described embodiments.

[0479] Figure 43 is a drawing showing a modified example of Figure 42.

[0480] Referring to FIG. 43, the driving force limiting member (3090) can be formed to be extended to have a length.

[0481] As a specific example, the driving force limiting member (3090) may be formed to extend so as to overlap at least one area of ​​the first driving unit (140) and the second driving unit (150).

[0482] As a preferred embodiment, the driving force limiting member (3090) may be formed to extend from the lowest end of the driving source unit (110) to a portion corresponding to the highest end of the second driving unit (150) based on FIG. 43.

[0483] In other words, the driving force limiting member (3090) can be formed to extend from the driving source (110) so as to cover both the first driving unit (140) and the second driving unit (150).

[0484] Figure 44 is a drawing showing another modified example of Figure 42.

[0485] Referring to FIG. 44, the driving force limiting member (3090) may be formed to be extended to have a length, and a plurality of members may be provided.

[0486] As a specific example, the driving force limiting member (3090) may be extended from the driving source unit (110) to cover the first driving unit (140). In addition, the driving force limiting member (3090) may be additionally provided, and the driving force limiting member (3090) may be arranged to cover the second driving unit (150).

[0487] In other words, the driving force limiting member (3090) can be divided into an element formed by extending from the driving source (110) to a height that can cover the first driving unit (140) and an element that covers the second driving unit (150).

[0488] To explain this from another perspective, it can be said that the driving force limiting member (3090) is provided on the upper and lower sides, respectively, with the third receiving section (135) as the boundary.

[0489] Figure 45 is an exploded perspective view illustrating an information output device according to one embodiment of the present invention.

[0490] The embodiment (30000) illustrated in FIG. 45 differs from the embodiment described with reference to FIGS. 16A to 16C in that it further includes a driving force limiting member (3090).

[0491] Accordingly, in the following, differences from the above-described embodiments will be mainly explained, and contents that are the same as the above-described embodiments or that can be easily modified by a person having ordinary knowledge in the technical field to which the present invention belongs from the above-described embodiments will be briefly explained or omitted.

[0492] Referring to FIG. 45, the information output device (30000) according to the present embodiment may include an upper unit (1100), a lower unit (1200), and a base unit (1300).

[0493] At this time, at least some space (1141) may be formed on the side of the upper unit (1100).

[0494] A driving force limiting member (3090) can be accommodated in the space formed in the upper unit (1100). The driving force limiting member (3090) according to the present embodiment is formed in a plate shape and can be formed in a shape corresponding to the space (1141) formed in the upper unit (1100).

[0495] The driving force limiting member (3090) is accommodated in a space (1141) formed on the side of the upper unit (1100) and can reduce or prevent the motion unit disposed inside the upper unit (1100) from interacting with or interfering with the driving force providing unit or other adjacent motion units.

[0496] Figure 46 is an exploded perspective view showing an information output device according to another embodiment of the present invention.

[0497] The embodiment (40000) illustrated in FIG. 46 differs from the embodiment described with reference to FIGS. 16A to 16C in that it further includes a driving force limiting member (3090).

[0498] Accordingly, in the following, differences from the above-described embodiments will be mainly explained, and contents that are the same as the above-described embodiments or that can be easily modified by a person having ordinary knowledge in the technical field to which the present invention belongs from the above-described embodiments will be briefly explained or omitted.

[0499] Referring to FIG. 46, the information output device (40000) according to the present embodiment may include an upper unit (1100), a lower unit (1200), and a base unit (1300).

[0500] At this time, a driving force limiting member (3090) may be further placed between the upper unit (1100) and the lower unit (1200).

[0501] The driving force limiting member (3090) is arranged between the upper unit (1100) and the lower unit (1200) to reduce or prevent the motion unit arranged inside the upper unit (1100) from interacting with or interfering with the driving force providing member or other adjacent motion units.

[0502] As an example, the driving force limiting member (3090) may be formed in the form of a tray. As a specific example, the driving force limiting member (3090) may include multiple grooves. These grooves can accommodate each of the plurality of motion units when provided. Accordingly, when a plurality of motion units are accommodated in corresponding grooves, the motion units may not interact with or interfere with each other due to the driving force limiting member (3090).

[0503] Figure 47 is an exploded perspective view showing an information output device according to another embodiment of the present invention.

[0504] The embodiment (50000) illustrated in FIG. 47 differs from the embodiment described with reference to FIGS. 16A to 16C in that it further includes a driving force limiting member (3090).

[0505] Accordingly, in the following, differences from the above-described embodiments will be mainly explained, and contents that are the same as the above-described embodiments or that can be easily modified by a person having ordinary knowledge in the technical field to which the present invention belongs from the above-described embodiments will be briefly explained or omitted.

[0506] Referring to FIG. 47, the information output device (50000) according to the present embodiment may include an upper unit (1100), a lower unit (1200), and a base unit (1300).

[0507] At this time, the information output device (50000) may further include a driving force limiting member (3090) formed to surround the periphery of the upper unit (1100).

[0508] The driving force limiting member (3090) may be formed in a ring shape so as to be able to surround the outer perimeter of the upper unit (1100). For example, if the upper unit (1100) is formed in a box shape, the driving force limiting member (3090) may be formed in a ring shape so as to be able to surround the box.

[0509] The driving force limiting member (3090) can reduce or prevent the motion unit disposed inside the upper unit (1100) from interacting with or interfering with other magnetic objects existing outside by wrapping around the perimeter of the upper unit (1100).

[0510] Meanwhile, as an optional embodiment, the upper unit (1100) may be provided with a receiving space along its periphery to accommodate a driving force limiting member (3090). In this case, the driving force limiting member (3090) may be accommodated in the receiving space formed in the upper unit (1100) so as to surround the upper unit (1100).
