[0035] Reference Figure 8 The information output device 1000 of an embodiment of the present invention includes at least one information output unit. Figure 1 An information output unit is shown.

[0036] Figure 2 The information output device is partially shown to be configured with a plurality of information output units, and the plurality of information output units can be connected to each other to form a group.

[0037] Reference Figure 1 , showing 1 information output unit, however, as an optional embodiment, such as Figure 2 , Figure 8 As shown, the information output device may include more than two information output units.

[0038] That is, according to the purpose, characteristics of the application product and user characteristics, the information output device 1000 may include different numbers of information output units IU1, IU2, IU3, IU4, IU5, IU6, IU7, IU8, IU9.

[0039] Reference Figure 1 , Figure 2 , Figure 8 The information output device of one embodiment of the present invention includes at least one information output unit. Figure 1 An information output unit is shown. That is, Figure 1 The information output device may be an information output unit.

[0040] Figure 1 , Figures 4 to 7 The figure is shown based on a single information output unit. Figure 1 An information output unit 100 (hereinafter referred to as information output device 100) is shown for description.

[0041] Reference Figure 1 , Figures 2 to 4 The information output device 100 according to an embodiment of the present invention may include a substrate portion 101 , a driving source portion 110 , a display portion 120 , a base portion 130 , a first driving portion 140 , a second driving portion 150 , and a shielding portion 170 .

[0042] Reference Figure 2The substrate portion 101 of an embodiment of the present invention is electrically connected to a power source and may include a substrate housing 102 , a circuit portion 103 , and a contact plate 104 .

[0043] Reference Figure 2 The substrate housing 102 is connected to a base portion 130 described later, and the base portion 130 can be disposed on the substrate housing 102. The circuit portion 103 is disposed on the substrate housing 102 and can be formed by a printed circuit board (PCB).

[0044] Reference Figure 1 , Figure 2 , Figure 4 The contact plate 104 of one embodiment of the present invention is disposed on the circuit portion 103 and can be disposed between the circuit portion 103 and a driving source portion 110 described later.

[0045] The contact plate 104 may be formed of a conductive material, and may transfer current from the circuit portion 103 to the driving source portion 110. The contact plate 104 may be arranged to contact the driving source portion 110 and the circuit portion 103, respectively.

[0046] Reference Figure 1 , Figure 2 , Figures 4 to 7 The driving source unit 110 of one embodiment of the present invention is configured to be connected to the substrate unit 101 to allow current to flow, and may be formed by a coil.

[0047] The driving source part 110 according to an embodiment of the present invention is formed of a coil, and thus a magnetic field is formed around the driving source part 110 when current flows.

[0048] The driving source part 110 may have various forms, may have a form in which a plurality of circuit wires are wound, and may be formed by changing the number of windings or the like.

[0049] Reference Figure 1 , Figure 2 , Figures 4 to 7 The driving source part 110 of one embodiment of the present invention is formed in a cylindrical shape with openings on both sides, but this is only for the convenience of description, which means the shape arranged on the outer side of the first driving part 140 described later when multiple circuit wires are wound as described above.

[0050] The first driving unit 140 described later may be driven by a magnetic field generated by the current flowing through the driving source unit 110 according to an embodiment of the present invention. As the first driving unit 140 is driven, the second driving unit 150 may perform angular motion or rotational motion.

[0051] Furthermore, as the first driving unit 140 and the second driving unit 150 are driven, a driving force may be provided to the expression unit 120 that is in direct or indirect contact with the first driving unit 140 and the second driving unit 150 .

[0052] Reference Figure 1 , Figure 2 , Figures 4 to 7 In one embodiment of the present invention, a first driving unit 140 described later may be disposed inside the driving source unit 110. The driving source unit 110 and the first driving unit 140 may share a length direction (with Figure 1 The vertical direction is the center axis of the reference.

[0053] Reference Figure 1 , Figure 2 , Figures 4 to 7 The driving source part 110 of one embodiment of the present invention can be disposed between the first driving part 140 and the shielding part 170 described later along the radial direction with the longitudinal central axis as a reference.

[0054] Since the driving source unit 110 is arranged on the inner side of the shielding unit 170, the external power is transmitted to the driving source unit 110 through the substrate unit 101. This has the effect that even if a magnetic field is formed in the driving source unit 110, it will not affect the driving source unit 110 and the first driving unit 140 of another information output device 100 close to a certain information output device 100.

[0055] That is, the plurality of information output devices 100 are not affected by each other's actions when being driven, and each information output device 100 can be driven independently.

[0056] Furthermore, the shielding part 170 blocks the transmission of the magnetic field generated by the driving source part 110 disposed inside to the outside, thereby achieving an effect that a plurality of information output devices 100 disposed close to each other can be driven independently and precisely.

[0057] Reference Figure 1 , Figure 2 , Figures 4 to 7 The display unit 120 of one embodiment of the present invention is formed and configured to be perceived by the user, and can move along a preset direction as driven by the first driving unit 140 and the second driving unit 150 described later.

[0058] The display portion 120 of an embodiment of the present invention can be upward or downward (with the length direction central axis as the reference) Figure 1 as the reference) for displacement.

[0059] Reference Figure 1 , Figure 2 , Figures 4 to 7 In one embodiment of the present invention, the display portion 120 may be arranged along a first direction (with Figure 4 as a reference) to move closer to the driving source portion 110, or in the opposite direction of the first direction (with Figure 5 as a reference) to move away from the driving source portion 110.

[0060] Reference Figure 1 , Figure 2 , Figure 4 The display portion 120 of one embodiment of the present invention may be exposed to the outside through the base portion 130 described later, specifically, through the inlet hole portion 133 h formed in the second accommodation portion 133 .

[0061] Since the expression part 120 is exposed to the outside, the user can sense the movement of the expression part 120 through the touch of fingers or through vision.

[0062] Reference Figure 1 , Figure 2 , Figure 4 In one embodiment of the present invention, the display portion 120 may include a display surface 121 and an outer peripheral surface 125 .

[0063] Reference Figure 1 , Figure 2 , Figure 4 The display surface 121 is an area in the display portion 120 that is relatively far from the driving source portion 110 and may include an area for user identification.

[0064] As an optional embodiment, the user may identify the display portion 120 through the entire area of ​​the display portion 120 , or may identify only the display surface 121 .

[0065] For example, the user may sense the movement of the expression portion 120 by touching the expression surface 121 , and the user may also easily sense the movement of the expression portion 120 through visual perception of the expression surface 121 .

[0066] Reference Figure 1 , Figure 2 In one embodiment of the present invention, the display surface 121 may be formed to be convex toward the outside and include a curved surface. However, it is not limited thereto and may include a columnar region. As an alternative embodiment, it may include a region in a cylindrical shape.

[0067] The display surface 121 of an embodiment of the present invention can be modified in various ways, for example, Figure 1 , the upper surface (with Figure 4 The display surface 121 has a flat shape (with the reference as the reference), and the edge portion formed in the radial direction from the center of the upper surface of the display surface 121 has a predetermined curvature radius.

[0068] Reference Figure 1 The outer peripheral surface 125 is a surface in the region of the display portion 120 facing the second driving portion 150 , and may constitute a lower region of the display portion 120 and be connected to the second driving portion 150 .

[0069] The second driving part 150 can transmit force to the display part 120 through the outer peripheral surface 125. Figure 4 As a reference), the outer peripheral surface 125 is moved along the first direction ( Figure 5 The display surface 121 is moved upwardly in the embodiment of the present invention so that the display surface 121 can be exposed to the outside and the user can feel the display portion 120.

[0070] Reference Figure 4 In one embodiment of the present invention, the outer peripheral surface 125 is connected to the performance surface 121, and the length from the central axis in the longitudinal direction to the radial direction of the performance portion 120 can be formed to be relatively maximum.

[0071] Reference Figure 2 , Figure 4 The outer peripheral surface 125 of one embodiment of the present invention may be in the shape of a circular plate, but is not limited thereto. Various deformations may be performed within the technical concept that the area of ​​the outer peripheral surface 125 is larger than the area of ​​the inlet hole portion 133h formed in the base portion 130, specifically formed in the second accommodating portion 133, such as forming it in a quadrilateral shape.

[0072] As an alternative embodiment, the outer peripheral surface 125 may be formed in a triangular shape within the technical concept that the distance from the center to the outer edge of the outer peripheral surface 125 is greater than the distance from the center to the inner peripheral surface of the inlet hole 133 h of the second accommodation portion 133 .

[0073] Since the area of ​​the outer peripheral surface 125 of one embodiment of the present invention is larger than the area of ​​the entrance hole portion 133h formed in the second accommodating portion 133, when the performance portion 120 obtains power from the second driving portion 150 and moves away from the driving source portion 110, the outer peripheral surface 125 is prevented from passing through the entrance hole portion 133h and escaping to the outside.

[0074] The display part 120 of an embodiment of the present invention can be formed of various materials, and can be formed of an insulating material as a light and durable material, specifically, can include an organic material such as a resin, and can also include an inorganic material such as a ceramic material.

[0075] However, the present invention is not limited thereto, and the display portion 120 may be implemented in various ways, such as being formed of a material such as metal or glass.

[0076] Reference Figure 1 , Figure 2 , Figures 4 to 7 The base portion 130 of an embodiment of the present invention is used to accommodate the driving source portion 110 , the first driving portion 140 , the second driving portion 150 and the display portion 120 , and may include a first accommodating portion 131 , a second accommodating portion 133 , and a third accommodating portion 135 .

[0077] The base portion 130 of one embodiment of the present invention may have a long extended shape so as to accommodate the driving source portion 110, the first driving portion 140, the second driving portion 150 and the display portion 120, and is formed to surround the driving source portion 110, the first driving portion 140, the second driving portion 150 and the display portion 120 as a whole.

[0078] Reference Figure 1 , Figure 2 , Figures 4 to 7 The first receiving portion 131 of one embodiment of the present invention receives the driving source portion 110, the first driving portion 140, and the shielding portion 170, and one side thereof (with Figure 2 The upper side (based on the upper side) can be combined with the third accommodating portion 135, and the other side (based on the upper side) facing the third accommodating portion 135 can be combined with the third accommodating portion 135. Figure 2 The lower side of the substrate 101 (with the substrate 102 as a reference) can be combined with the substrate portion 101, specifically, can be combined with the substrate housing 102.

[0079] Reference Figure 2 In one embodiment of the present invention, the upper surface of the first receiving portion 131 (with Figure 2 A hole portion (not provided with a reference numeral) may be formed, and the first driving unit 140 and the second driving unit 150 may be arranged to face each other through the hole portion.

[0080] Reference Figure 2 In one embodiment of the present invention, the upper surface of the first receiving portion 131 (with Figure 2 A guide portion 132 is formed extending upward.

[0081] The guide portion 132 can pass through the third receiving guide groove portion 135gh formed in the third receiving portion 135 and the second receiving guide groove portion 133gh formed in the second receiving portion 133, thereby enabling the first receiving portion 131, the second receiving portion 133, and the third receiving portion 135 to be arranged in the height direction (in degrees). Figure 2 The effect of aligning and stabilizing the combination is achieved.

[0082] Reference Figure 2 In one embodiment of the present invention, the outer end of the guide portion 132 is aligned with the length direction of the guide portion 132 (in Figure 2 A hook portion 132p is formed to protrude at a predetermined angle with respect to the vertical direction (with the vertical direction as a reference).

[0083] Since the hook portion 132 p is formed to be protruding, it can be combined with the guide protrusion 133 p formed in the second receiving portion 133 in a snap-fitting manner, which has the effect of improving the fastening force between the first receiving portion 131, the second receiving portion 133, and the third receiving portion 135.

[0084] Reference Figure 1 , Figure 2 , Figures 4 to 7The second receiving portion 133 of one embodiment of the present invention is disposed opposite to the first receiving portion 131 and receives the display portion 120, and can be disposed on the upper surface (with Figure 2 An inlet hole portion 133h is formed on the basis of the present invention so that the performance portion 120, especially the performance surface 121, protrudes and is exposed to the outside.

[0085] The first receiving portion 131 and the second receiving portion 133 of an embodiment of the present invention may be disposed adjacent to each other and may be disposed so as not to overlap each other.

[0086] Reference Figure 1 , Figure 2 , Figure 4 In one embodiment of the present invention, a third accommodating portion 135 may be disposed between the first accommodating portion 131 and the second accommodating portion 133 , and a second driving portion 150 may be disposed in the third accommodating portion 135 in a manner that allows for angular motion or rotational motion.

[0087] Reference Figure 2 In one embodiment of the present invention, a second receiving guide groove portion 133gh is formed in a groove shape on one side of the second receiving portion 133, and the second receiving guide groove portion 133gh can be inserted into the guide portion 132 formed in the first receiving portion 131.

[0088] When the second receiving portion 133 moves toward the first receiving portion 131 to be coupled with the first receiving portion 131 , the guide portion 132 formed in the first receiving portion 131 may be inserted along the second receiving guide groove portion 133 gh formed in the second receiving portion 133 .

[0089] Therefore, the second receiving portion 133 can move toward the first receiving portion 131 along a preset coupling path and be coupled with the third receiving portion 135 disposed on the upper side of the first receiving portion 131 .

[0090] Reference Figure 2 In one embodiment of the present invention, a guide protrusion 133p may be formed on the inner side of the second receiving guide groove 133gh formed in the second receiving portion 133 to protrude outward.

[0091] Since the guide protrusion 133p is formed to protrude from the inside of the second receiving guide groove 133gh toward the outside, the hook 132p formed on the guide portion 132 is coupled to the guide protrusion 133p in a snap-fitting manner.

[0092] Furthermore, since the guide protrusion 133 p and the hook 132 p are engaged with each other in a snap-fitting manner, there is an effect of preventing the first receiving portion 131 and the second receiving portion 133 from being released after they are engaged with each other via the third receiving portion 135 .

[0093] Reference Figure 2In one embodiment of the present invention, the guide portion 132 formed in the first accommodating portion 131, the second accommodating guide groove portion 133gh formed in the second accommodating portion 133, the guide protrusion portion 133p and the third accommodating guide groove portion 135gh formed in the third accommodating portion 135 can be formed on one side of the base portion 130, but are not limited to this, and can be respectively equipped in pairs and arranged opposite to each other.

[0094] Therefore, there is an effect of improving the fastening force between the first accommodation portion 131 , the second accommodation portion 133 , and the third accommodation portion 135 .

[0095] Reference Figure 1 , Figure 2 , Figure 4 The third receiving portion 135 of one embodiment of the present invention connects the first receiving portion 131 and the second receiving portion 133, and may be provided with a second driving portion 150. In the third receiving portion 135 of one embodiment of the present invention, the second driving portion 150 may be rotatably provided.

[0096] Reference Figure 2 In one embodiment of the present invention, a third receiving guide groove portion 135gh may be formed in a groove shape on one side of the third receiving portion 135 , and the third receiving guide groove portion 135gh may be formed to communicate with the second receiving guide groove portion 133gh formed in the second receiving portion 133 .

[0097] Reference Figure 2 Since the third accommodating guide groove portion 135gh of one embodiment of the present invention is formed in a groove shape, the guide portion 132 formed in the first accommodating portion 131 can pass through the second accommodating guide groove portion 133gh and the third accommodating guide groove portion 135gh, and the third accommodating portion 135 and the second accommodating portion 133 can be stacked in sequence on the first accommodating portion 131, which has the effect of providing a coupling path for the first accommodating portion 131, the second accommodating portion 133, and the third accommodating portion 135.

[0098] Reference Figure 2 In one embodiment of the present invention, the third accommodating portion 135 may be formed with a groove portion having a curved surface shape (not marked in the figure), which can accommodate the second driving portion 150 described later, specifically, the driving control portion 153 protruding from the second driving body 151.

[0099] The driving control unit 153 according to an embodiment of the present invention can rotate along the rotation center axis AX in a clockwise direction or a counterclockwise direction inside the groove.

[0100] The second driving unit 150 may be provided with a plurality of driving control units 153 , which may be formed to protrude on both sides, and a plurality of grooves for placing the driving control units 153 may be provided corresponding to the plurality of driving control units 153 .

[0101] Reference Figure 2 In the third accommodating portion 135 of one embodiment of the present invention, a hole portion (not marked) communicating with the hole portion formed in the first accommodating portion 131 may be formed, and a support rod 136 connecting a preset area may be extended from the hole portion.

[0102] Reference Figure 2 The support rod 136 of one embodiment of the present invention can contact and support the lower surface (with Figure 4 Specifically, the support rod 136 and the lower surface of the second driving part 150 may be arranged in surface contact.

[0103] Reference Figure 2 , Figure 4 Since the support rod 136 is formed in the third accommodating portion 135 of an embodiment of the present invention, the rotation radius of the second driving portion 150 can be limited when the second driving portion 150 rotates with the longitudinal central axis of the driving control portion 153 as the rotation central axis.

[0104] That is, since the lower surface of the second driving part 150 (with Figure 4 As a reference, the second driving portion 150 is buckled with the supporting rod 136, thereby preventing the second driving portion 150 from rotating toward the first driving portion 140 accommodated in the first accommodating portion 131 through the corresponding position, and stably supporting the position of the second driving portion 150.

[0105] Reference Figure 1 , Figure 2 , Figures 4 to 7 In one embodiment of the present invention, the first driving portion 140 is accommodated in the base portion 130 and may include a first magnetic portion 145 .

[0106] The first magnetic portion 145 of an embodiment of the present invention may contain a magnetic material, and may be formed of a permanent magnet, specifically, a magnet with a relatively low coercive force (eg, an alnico magnet, etc.).

[0107] Reference Figure 1 , Figure 4 The first driving portion 140 of an embodiment of the present invention can be accommodated in the base portion 130 , specifically, can be accommodated in the first accommodation portion 131 , and can be arranged adjacent to the driving source portion 110 accommodated in the first accommodation portion 131 .

[0108] Specifically, the first driving part 140 may be disposed inside the driving source part 110. The first driving part 140 may share a central axis in the longitudinal direction with the driving source part 110.

[0109] The magnetic force of the first magnetic portion 145 of one embodiment of the present invention may be greater than that of the second magnetic portion 155 of the second driving portion 150 .

[0110] Therefore, when the external force applied by the user acts on the display part 120 and causes the second driving part 150 to be unable to rotate, after the external force applied to the display part 120 is removed, the second magnetic part 155 and the second driving body 151 configured with the second magnetic part 155 rotate with the aid of the magnetic force of the first magnetic part 145, which has the effect of making the display part 120 move along the first direction and the opposite direction.

[0111] That is, even if power is only provided for a relatively short period of time due to the external force applied to the performance part 120, resulting in the inability to transmit power to the second drive part 150 via the drive source part 110 and the first drive part 140, the first drive part 140 will be configured to have polarity in a preset direction with the help of the current applied to the drive source part 110. When the external force applied to the performance part 120 is removed, the second drive part 150 can perform angular motion or rotational motion according to the polarity of the first magnetic part 145 possessed by the first drive part 140.

[0112] The first magnetic portion 145 of one embodiment of the present invention may include a first magnetic region 145a (N pole or S pole) and a second magnetic region 145b (S pole or N pole) having different polarities. The first magnetic region 145a and the second magnetic region 145b having different polarities may be located at one point of the first magnetic portion 145, along a direction from the driving source portion 110 toward the performance portion 120, for example, along an up-down direction (with a Figure 1 Arranged in the direction of (as the reference).

[0113] Reference Figure 4 The first magnetic portion 145 of one embodiment of the present invention can be fixed in the inner side of the driving source portion 110 and move in the up-down direction (with Figure 4 A first magnetic region 145a and a second magnetic region 145b are formed on the first magnetic portion 145 (based on the driving source portion 110). When current is applied to the driving source portion 110, the polarities of the first magnetic region 145a and the second magnetic region 145b formed on the first magnetic portion 145 change.

[0114] In the information output device 100 of one embodiment of the present invention, the driving source part 110 surrounds the first magnetic part 145, and the polarity of the first magnetic part 145 changes as the current is applied to the driving source part 110. However, the present invention is not limited to this, and various deformation implementations can be performed within the technical concept that the current is directly or indirectly applied to the first magnetic part 145, and the polarity of the first magnetic region 145a and the second magnetic region 145b is changed.

[0115] As the first magnetic region 145 a and the second magnetic region 145 b located in the first magnetic portion 145 form polarities, power can be transmitted to the second driving portion 150 . Specifically, an attractive force or a repulsive force can be generated for the second magnetic portion 155 included in the second driving portion 150 .

[0116] That is, as current is applied to the driving source unit 110, polarity is formed in the first driving unit 140, specifically in the first magnetic unit 145, and the second magnetic unit 155 of the second driving unit 150 can be pushed or pulled according to the polarity formed in the first magnetic region 145a relatively close to the second driving unit 150.

[0117] By virtue of the interaction between the first magnetic portion 145 of the first driving portion 140 and the second magnetic portion 155 of the second driving portion 150 according to an embodiment of the present invention, the second driving portion 150 can perform angular motion or rotational motion to transmit power to the display portion 120 .

[0118] Reference Figures 1 to 4 The second driving unit 150 of one embodiment of the present invention is disposed between the first driving unit 140 and the display unit 120 , and is rotatably disposed on the base unit 130 .

[0119] The second driving unit 150 may perform angular motion or rotational motion as driven by the first driving unit 140 , and transmit power to the expression unit 120 .

[0120] Reference Figures 4 to 7 , the second driving unit 150 according to an embodiment of the present invention can maintain a contact state with the display unit 120 .

[0121] Therefore, if the second driving unit 150 obtains power from the first driving unit 140 and performs angular motion or rotational motion, the display unit 120 in contact with the second driving unit 150 may move in a first direction (in a direction away from the driving source unit 110 or the first driving unit 140) away from the driving source unit 110 or the first driving unit 140. Figure 4 as the reference, from bottom to top) or the opposite direction (based on Figure 4 As a reference, move from top to bottom).

[0122] Reference Figure 4 In one embodiment of the present invention, the second driving unit 150 may be arranged at a preset interval from the first driving unit 140 .

[0123] Reference Figure 1 , Figure 3 , Figure 4 In one embodiment of the present invention, the second driving unit 150 may include a second driving body 151 and a second magnetic unit 155 .

[0124] Reference Figures 1 to 4The second driving body 151 accommodates the second magnetic portion 155 , which can be accommodated in the base portion 130 , specifically in the third accommodation portion 135 .

[0125] Reference Figure 1 , Figures 4 to 7 The second driving body 151 of one embodiment of the present invention is rotatably disposed in the third receiving portion 135. An accommodating space for accommodating the second magnetic portion 155 is formed inside the second driving body 151.

[0126] Reference Figure 3 , Figure 4 The second driving body 151 of one embodiment of the present invention may be formed into a plurality of surfaces along the circumferential direction of the rotation center axis AX, and may be formed with a driving surface 151a, a base surface 151b, and a connecting surface 151c along the circumference of the rotation center axis AX.

[0127] Reference Figure 3 , Figure 4 The driving surface 151 a is a surface in contact with the expression portion 120 and can maintain a state of contact with the expression portion 120 .

[0128] With the rotation center axis AX of the second driving body 151 as a reference, along the circumferential direction, one side of the driving surface 151 a may be connected to the base surface 151 b , and the other side facing the base surface 151 b may be connected to the connection surface 151 c .

[0129] Reference Figure 3 , Figure 4 A curved surface portion 152 may be formed in a region where the driving surface 151a and the base surface 151b are connected. The curved surface portion 152 may have a predetermined radius of curvature. The curved surface portion 152 may be formed to be convex toward the outer side.

[0130] As an optional embodiment, the curved surface portion 152 may include a boundary line having a circular shape.

[0131] The curved surface portion 152 formed in a predetermined area of ​​the driving surface 151a may be formed on the side of the second driving body 151 protrudingly formed with the driving control portion 153 (in Figure 4 The left side facing the other side (based on Figure 4 is formed on the right side of the reference).

[0132] Since a curved surface 152 is formed in the area where the driving surface 151a and the base surface 151b are connected, when the second driving body 151 obtains power from the first driving part 140 and performs angular motion or rotational motion, the expression part 120 moves gently along the curved surface 152 formed on the driving surface 151a, so that continuous and natural motion can be performed efficiently.

[0133] In addition, the expression portion 120 is arranged in a first direction away from the driving source portion 110 (in Figure 4As a reference, from bottom to top) and then move in the opposite direction (based on Figure 6 As a reference, when moving from top to bottom), the performance portion 120 can move softly while maintaining contact with the second driving body 151.

[0134] Reference Figure 3 , Figure 4 The base surface 151b formed on the second driving body 151 contacts the base portion 130, specifically the third accommodating portion 135. With the rotation center axis AX of the second driving body 151 as a reference, along the peripheral direction, one side of the base surface 151b (with Figure 4 The left side of the base surface 151b (based on Figure 4 The right side of the reference surface 151 can be connected to the driving surface 151a.

[0135] The base surface 151b may be flat and arranged on the third receiving portion 135 in a state of surface contact with the support rod 136 formed in the third receiving portion 135. Figure 4 The second driving body 151 can be stably supported on the third accommodation portion 135.

[0136] Reference Figure 3 , Figure 4 The connection surface 151c formed on the second driving body 151 as a surface connecting the base surface 151b and the driving surface 151a may be formed flat. The section where the connection surface 151c and the base surface 151b are connected may have a predetermined curvature radius and be formed into a curved surface shape.

[0137] Therefore, when the second driving body 151 rotates with the lengthwise central axis of the driving control unit 153 described later as the rotation central axis AX, the second driving body 151 can stably rotate on the third accommodation portion 135 .

[0138] Reference Figure 3 , Figure 4 Except for the section where the connection surface 151c is connected to the base surface 151b, the flattened area may have a predetermined angle. Therefore, the rotation range of the second driving body 151 based on the rotation center axis AX can be limited.

[0139] That is, a virtual straight line passing through a region formed flatly on the connection surface 151 c and a virtual straight line passing through a region formed flatly on the base surface 151 b may be arranged to form a predetermined angle.

[0140] In one embodiment of the present invention, the flat surfaces of the connecting surface 151 c and the base surface 151 b can be perpendicular to each other, and the rotation range of the second driving body 151 can be set to 90 degrees.

[0141] However, the invention is not limited thereto, and the angle formed by the flat surfaces of the connecting surface 151 c and the base surface 151 b may be set according to the rotation range of the second driving body 151 .

[0142] Reference Figure 5 Since the connection surface 151 c is formed flat, when the second driving body 151 rotates, the connection surface 151 c can make surface contact with the support rod 136 formed in the third accommodation portion 135 and stably maintain the position.

[0143] Reference Figures 3 to 7 In one embodiment of the present invention, a drive control unit 153 may be formed on both sides of the second drive body 151 protruding outward. The drive control unit 153 may be formed extending along the longitudinal central axis, and the longitudinal central axis of the drive control unit 153 may be formed by the rotation central axis AX of the second drive body 151.

[0144] Reference Figures 3 to 7 The driving control unit 153 of one embodiment of the present invention is set at a location separated by a specified distance from the center, with the side surface of the second driving body 151 protruding and formed with the driving control unit 153 as a reference.

[0145] In this specification, the side surface of the second driving body 151 refers to Figures 4 to 7 One side of the second driving body 151 seen from the front.

[0146] That is, refer to Figure 4 The driving control unit 153 is biased toward one side (with the center of the second driving body 151 as the reference) Figure 4 , and is located on the longitudinal center axis of the first driving unit 140.

[0147] The curved surface 152 of one embodiment of the present invention can be located at the side where the driving control unit 153 is located (with the center of the second driving body 151 as the reference). Figure 4 The left side facing the other side (based on Figure 4 As a result, the following effects are achieved: when the second driving body 151 rotates with the longitudinal central axis AX of the driving control unit 153 as the rotation central axis, a torque can be easily generated, so that the second driving unit 150 performs an angular motion or a rotational motion, thereby efficiently performing the motion of the display unit 120 and improving the precision expression of the information output device 100.

[0148] Furthermore, since the torque applied to the second driving unit 150 is easily generated, there is an effect of saving power consumption of the information output device 100 .

[0149] Reference Figures 4 to 7The driving control part 153 formed on both side surfaces of the second driving body 151 is placed in the groove of the third accommodating part 135 and can rotate in the groove in a clockwise direction or a counterclockwise direction.

[0150] That is, the second driving unit 150 according to an embodiment of the present invention can rotate in a clockwise direction or a counterclockwise direction with the second driving control unit 153 as a rotation center.

[0151] Reference Figures 1 to 7 The second magnetic portion 155 of one embodiment of the present invention is disposed inside the second driving body 151 and may have regions with different polarities.

[0152] The second magnetic portion 155 of one embodiment of the present invention may include a magnetic material, for example, a permanent magnet. The magnetic force of the second magnetic portion 155 may be smaller than the magnetic force of the first magnetic portion 145 .

[0153] Therefore, since the area formed by the first magnetic part 145 in the second magnetic part 155 changes, the second driving part 150 accommodating the second magnetic part 155 can move, but can prevent the magnetic area formed in the first magnetic part 145 from changing due to the magnetic force of the second magnetic part 155.

[0154] In other words, when the external force applied by the user acts on the display part 120 and causes the second driving part 150 to be unable to rotate, after the external force applied to the display part 120 is removed, the second magnetic part 155 and the second driving body 151 configured with the second magnetic part 155 rotate with the aid of the magnetic force of the first magnetic part 145, thereby causing the display part 120 to move in the first direction and the opposite direction.

[0155] That is, it has the following effect: even if power is only provided for a relatively short period of time due to the external force applied to the performance part 120, resulting in the inability to transmit power to the second drive part 150 via the first drive part 140, the first drive part 140, specifically, the first magnetic part 145 will form polarity in a preset direction with the help of the power obtained from the driving source part 110. If the external force applied to the performance part 120 is removed, the second drive part 150 can perform angular motion or rotational motion with the help of the first drive part 140.

[0156] Reference Figures 4 to 7 The second magnetic portion 155 of one embodiment of the present invention may be separated from the curved portion 152 formed on the second driving body 151 and relatively close to the rotation center axis AX of the second driving body 151 .

[0157] That is, it can be overlapped with the drive control part 153 protruding from the second drive body 151. Therefore, as current is applied to the drive source part 110, the first drive part 140, specifically, the first magnetic part 145 forms polarity, and an attractive force and a repulsive force are generated between the first magnetic part 145 and the second magnetic part 155, and the curved surface part 152 arranged away from the rotation center axis rotates in the clockwise direction or the counterclockwise direction, which has the effect of easily generating a torque for the second drive part 150.

[0158] Reference Figure 4 The lengthwise central axis of the driving control portion 153 formed on the second driving body 151 may intersect the lengthwise central axis of the first magnetic portion 145 perpendicularly.

[0159] Reference Figures 4 to 7 The second magnetic portion 155 of one embodiment of the present invention may include a first magnetic region 155a (N pole or S pole) and a second magnetic region 155b (S pole or N pole) with different polarities. The first magnetic region 155a and the second magnetic region 155b with different polarities may be arranged along the height direction of the second driving body 151 (with Figure 4 Configuration based on the up and down directions.

[0160] Reference Figures 4 to 7 By means of the attraction and repulsion generated between the second magnetic part 155 and the first magnetic part 145 of one embodiment of the present invention, the second driving body 151 can drive the longitudinal central axis AX of the control part 153 as the rotation central axis to rotate clockwise or counterclockwise, so that the display part 120 can rotate in the up and down direction (with Figure 4 as the basis) to move.

[0161] Reference Figure 1 , Figure 2 , Figure 4 The shielding portion 170 of an embodiment of the present invention is accommodated in the base portion 130, specifically, in the first accommodation portion 131, and a hollow space may be formed inside thereof.

[0162] The shielding part 170 of one embodiment of the present invention can be disposed between the first accommodating part 131 and the driving source part 110 and can be formed of a high magnetic permeability material. The shielding part 170 can be formed in a shape that wraps the driving source part 110, and is used to block the magnetic field generated by applying current to the driving source part 110 from being transmitted to the outside.

[0163] Furthermore, the single information output device 100 composed of the driving source unit 110, the first driving unit 140, the second driving unit 150, and the display unit 120 can avoid causing magnetic field influence on other adjacent information output units, so that multiple information output units can be driven independently.

[0164] The shielding portion 170 of an embodiment of the present invention may be formed in a cylindrical shape, but is not limited thereto and may be implemented in various modifications.

[0165] The working principle and effect of the information output device 100 according to an embodiment of the present invention are described as follows.

[0166] Reference Figures 1 to 7 The information output device 100 according to an embodiment of the present invention may include a substrate portion 101 , a driving source portion 110 , a display portion 120 , a base portion 130 , a first driving portion 140 , a second driving portion 150 , and a shielding portion 170 .

[0167] Reference Figure 1 , Figures 4 to 7 In one embodiment of the present invention, the driving source portion 110 may be formed by a coil, and a current may be connected from an external power source through the substrate portion 101 to form a magnetic field.

[0168] By means of the magnetic field formed in the driving source part 110 , different polarities can be formed in the first driving part 140 , specifically in the first magnetic part 145 .

[0169] Reference Figure 4 The first magnetic region 145a formed on the first magnetic portion 145 due to the current applied to the driving source portion 110 can constitute the S pole, and the second magnetic region 145b formed on the first magnetic portion 145 relatively closer to the substrate portion 101 than the first magnetic region 145a constitutes the N pole.

[0170] Reference Figure 4 The first magnetic region 155a formed on the second magnetic portion 155 accommodated inside the second driving body 151 can constitute an S pole, and the second magnetic region 155b formed on the second magnetic portion 155 relatively closer to the performance portion 120 than the first magnetic region 155a can constitute an N pole.

[0171] The polarity configuration of the second magnetic portion 155 is that the first magnetic region 155 a forms an S pole and the second magnetic region 155 b forms an N pole, so a repulsive force is generated between the second magnetic portion 155 and the first magnetic portion 145 .

[0172] Reference Figure 4 , Figure 5 As the repulsive force is generated between the first magnetic portion 145 and the second magnetic portion 155, the second driving body 151 can rotate counterclockwise (with Figure 5 as a reference) for rotation.

[0173] That is, the first magnetic region 155 a formed on the second magnetic portion 155 intends to move to a position away from the driving source portion 110 , and the second magnetic region 155 b moves to a position close to the driving source portion 110 by the attraction.

[0174] Since the drive control unit 153 is disposed on the longitudinal center axis of the first magnetic unit 145, the curved surface 152 formed by the area where the drive surface 151a in the drive body is connected to the base surface 151b is disposed away from the longitudinal center axis of the drive control unit 153 and the first magnetic unit 145, so that torque can be easily generated.

[0175] Furthermore, the second driving unit 150 can be made to perform angular motion or rotational motion, and the expression unit 120 can be efficiently moved, thereby improving the precision expression of the information output device 100.

[0176] In particular, since the torque is easily generated for the second driving unit 150 , the power consumption of the information output device 100 can be reduced.

[0177] As the second driving unit 150 rotates, the display unit 120 also moves along the curved surface 152 away from the driving source unit 110 and the first driving unit 140 (in degrees). Figure 5 As a reference, move from bottom to top).

[0178] Reference Figure 5 Since the connection surface 151c respectively connected to the driving surface 151a and the base surface 151b is formed flat, the virtual straight line passing through the connection surface 151c is perpendicular to the virtual straight line passing through the base surface 151b, thereby limiting the second driving part 150 from rotating above a preset angle.

[0179] Reference Figure 6 , Figure 7 , showing a state where the power applied to the driving source unit 110 is cut off, which is different from Figure 4 The first magnetic region 145a formed on the first magnetic portion 145 forms an N pole, and the second magnetic region 145b formed on the first magnetic portion 145 relatively closer to the substrate portion 101 than the first magnetic region 145a forms an S pole.

[0180] Therefore, the first magnetic region 155a of the second magnetic portion 155 arranged relatively close to the first magnetic portion 145 moves toward the driving source portion 110 due to attraction, and the second magnetic region 155b of the second magnetic portion 155 moves away from the driving source portion 110 due to repulsion.

[0181] In other words, the second driving body 151 rotates in the clockwise direction with the longitudinal central axis of the driving control unit 153 as the rotation central axis AX.

[0182] Therefore, the expression part 120 which keeps contact with the second driving body 151, specifically the driving surface 151a, moves in the direction of the driving source part 110 (in Figure 6 As a reference, move from top to bottom).

[0183] The driving source part 110 of the information output device 100 of one embodiment of the present invention surrounds the first driving part 140. As current is applied to the driving source part 110, the polarity of the first magnetic part 145 changes, and power is transmitted to the second driving part 150 due to the interaction with the second magnetic part 155 equipped with the second driving part 150.

[0184] In addition, by means of the current applied to the driving source part 110, the first driving part 140 can change the polarity of the first magnetic part 145 while maintaining the position, which has the effect of simplifying the structure because no additional power transmission structure is required.

[0185] In addition, a curved surface 152 is formed in the area where the driving surface 151a formed by the second driving body 151 connects the base surface 151b, so that when the expression part 120 moves, the expression part 120 maintains contact with the second driving body 151 and moves gently, and can efficiently perform continuous and natural movements.

[0186] The specific implementation described in the present invention is only an embodiment and does not limit the scope of the present invention in any way. In addition, the line connections or connecting members between the constituent elements shown in the figures exemplarily show functional connections and / or physical connections or circuit connections, which can be replaced or shown as various additional functional connections, physical connections or circuit connections in actual devices. In addition, if there is no specific description such as "necessary" or "importantly", it may not be a constituent element necessary for the application of the present invention.

[0187] Therefore, the idea of ​​the present invention is not limited to the embodiments described above, and the claims and all scopes equivalent to the claims or equivalently changed thereby belong to the idea of ​​the present invention.
