Referring to FIGS. 4 to 7 , the second driving unit 150 according to an embodiment of the present invention may maintain contact with the expression unit 120.

As a result, when the second driving unit 150 receives power from the first driving unit 140 and makes angular or rotational movement, the expression unit 120 in contact with the second driving unit 150 is connected to the driving source unit 110 or the first driving unit 140. It may be moved in a first direction away from the driving unit 140 (from the bottom to the top in FIG. 4) or in the opposite direction (from the top to the bottom in FIG. 4).

An accommodating space capable of accommodating the second magnetic unit 155 may be formed inside the second driving body 151.

Referring to FIGS. 3 and 4, the second driving body 151 according to an embodiment of the present invention may be formed of a plurality of surfaces along the circumferential direction of the rotation center axis (AX). A driving surface 151a, a base surface 151b, and a connection surface 151c may be formed along the circumference.

Referring to FIGS. 3 and 4 , the driving surface 151a is a surface in contact with the expression unit 120 and can remain in contact with the expression unit 120 .

One side of the driving surface (151a) in the circumferential direction based on the rotation center axis (AX) of the second driving body 151 is connected to the base surface (151b), and the other side opposite to this is connected to the connection surface (151c). You can.

Since the curved portion 152 is formed in the area where the driving surface 151a and the base surface 151b are connected, power is transmitted from the first driving part 140 and the second driving body 151 moves angularly or rotationally. When this happens, the expression unit 120 can move smoothly along the curved part 152 formed on the driving surface 151a and efficiently perform continuous and natural movement.

In addition, when the expression unit 120 moves in the first direction away from the driving source unit 110 (from the bottom to the top in FIG. 4) and then moves in the opposite direction (from the top to the bottom in FIG. 6), the expression unit 120 moves There is an effect of being able to move smoothly while maintaining contact with the second driving body 151.

Referring to Figures 3 and 4, the base surface 151b formed on the second driving body 151 is in contact with the base part 130, specifically the third receiving part 135, and is in contact with the second driving body (151).

The base surface 151b may be formed flat and may be disposed on the third accommodating part 135 in a state of surface contact with the support bar 136 formed in the third accommodating part 135. This has the effect of maintaining the initial position (position in FIG. 4) of the second driving body 151 and stably supporting the second driving body 151 on the third receiving portion 135.

Referring to Figures 3 and 4, the connection surface 151c formed on the second driving body 151 is a surface connecting the base surface 151b and the driving surface 151a, and may be formed flat. The section where the connection surface 151c and the base surface 151b are connected may have a predetermined radius of curvature and may be formed in a curved shape.

Due to this, the second driving body 151 can be stably rotated on the third receiving part 135 when rotating using the longitudinal central axis of the driving control unit 153, which will be described later, as the rotational central axis AX.

Referring to FIGS. 3 and 4 , the flat area except for the section where the connection surface 151c and the base surface 151b are connected may be arranged at a predetermined angle. As a result, the rotation range of the second driving body 151 can be limited based on the rotation central axis AX.

That is, a virtual straight line passing through a flat area on the connection surface 151c and a virtual straight line passing through a flat area on the base surface 151b may be arranged at a predetermined angle.

The flat surfaces of the connection surface 151c and the base surface 151b according to an embodiment of the present invention are perpendicular to each other, and the rotation range of the second driving body 151 can be set to 90 degrees.

However, it is not limited to this, and of course, the angle formed by the flat surfaces of the connection surface 151c and the base surface 151b can be formed in various ways depending on the rotation range of the second driving body 151.

Referring to FIG. 5, since the connection surface 151c is formed flat, when the second driving body 151 rotates, the connection surface 151c is formed in the third receiving portion 135 and the support bar 136. It contacts the surface and can maintain its position stably.

Referring to Figures 3 to 7, drive control units 153 may be formed to protrude outward on both sides of the second driving body 151 according to an embodiment of the present invention. The drive control unit 153 may be formed to extend along a longitudinal central axis, and the longitudinal central axis of the drive control unit 153 may be formed as the rotation center axis AX of the second drive body 151.

Due to this, when the second driving body 151 rotates with the longitudinal central axis (AX) of the driving control unit 153 as the rotational axis, torque force can be easily generated, By causing the second driving unit 150 to perform angular or rotational movement, the movement of the expression unit 120 can be efficiently carried out and the precise expression of the information output device 100 can be improved.

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

That is, it can be arranged to overlap with the drive control unit 153 protruding from the second drive body 151. As a result, current is applied to the drive source unit 110, and the polarity of the first drive unit 140, specifically the first magnetic unit 145, is formed, thereby forming a gap between the first magnetic unit 145 and the second magnetic unit 155. Attractive force and repulsive force are generated, and the curved portion 152, which is spaced apart from the central axis of rotation, rotates clockwise or counterclockwise, which has the effect of easily generating a torque force for the second driving portion 150.

Referring to FIG. 4, the longitudinal central axis of the drive control unit 153 formed in the second driving body 151 and the longitudinal central axis of the first magnetic unit 145 may be perpendicular to each other.

Referring to FIGS. 4 to 7, the second magnetic portion 155 according to an embodiment of the present invention includes a first magnetic region 155a (N pole or S pole) and a second magnetic region (155a) of different polarities, respectively. 155b) (S-pole or N-pole), and the first magnetic region 155a and the second magnetic region 155b of different polarities are located in the height direction of the second driving body 151 (up and down based on FIG. 4). direction) can be placed.

The shielding unit 170 may be formed to surround the driving source unit 110 and block the magnetic field generated when a current is applied to the driving source unit 110 from being transmitted to the outside.

In addition, a magnetic field is applied to another information output unit disposed adjacent to the single information output device 100 consisting of the driving source unit 110, the first driving unit 140, the second driving unit 150, and the expression unit 120. This ensures that multiple information output units can be driven independently.

The shielding portion 170 according to an embodiment of the present invention is formed in a cylindrical shape, but is not limited to this and various modifications are possible.

The operating principle and effects of the information output device 100 according to an embodiment of the present invention as described above will be described.

Referring to FIGS. 1 and 4 to 7, the drive source unit 110 according to an embodiment of the present invention may be formed as a coil, and a magnetic field is formed by receiving current from an external power source through the substrate unit 101. It can be.

Different polarities may be formed in the first driving unit 140, specifically the first magnetic unit 145, by the magnetic field formed in the driving source unit 110.

Referring to FIG. 4, the first magnetic region 145a formed on the first magnetic portion 145 when the driving source portion 110 receives current may be formed as an S pole, and the first magnetic portion 145 The second magnetic region 145b, which is formed relatively closer to the substrate portion 101 than the first magnetic region 145a, may be formed as an N pole.

Referring to FIG. 4, the first magnetic region 155a formed on the second magnetic portion 155 accommodated inside the second driving body 151 is the S pole, and the first magnetic region 155a is formed on the second magnetic portion 155.

The polarity arrangement of the second magnetic section 155 is such that the first magnetic region 155a is formed as the S pole and the second magnetic region 155b is formed as the N pole, and accordingly, the second magnetic region 155 is formed as the first magnetic region 155. A repulsive force is generated in the relationship with the unit 145.

Referring to FIGS. 4 and 5, as a repulsive force is generated between the first magnetic force unit 145 and the second magnetic force unit 155, the second drive body 151 rotates the drive control unit 153 to the rotation center axis (AX). It can be rotated counterclockwise (based on FIG. 5).

That is, the first magnetic region 155a formed on the second magnetic portion 155 tries to move to a position away from the driving source portion 110, and the second magnetic region 155b moves toward the driving source portion 110 by attraction. It moves to a location closer to .

The drive control unit 153 is disposed on the longitudinal central axis of the first magnetic unit 145, and a curved portion 152 is formed in the area where the drive surface 151a and the base surface 151b are connected in the drive body portion. As the drive control unit 153 and the first magnetic unit 145 are spaced apart from the longitudinal central axis, torque force can be easily generated.

In addition, by allowing the second driving unit 150 to perform angular or rotational movement, the movement of the expression unit 120 can be carried out efficiently and the precise expression of the information output device 100 can be improved.

As the second driving unit 150 rotates, the expression unit 120 also moves along the curved surface unit 152 in a direction away from the driving source unit 110 and the first driving unit 140 (direction from the bottom to the top based on FIG. 5). I do it.

Referring to FIG. 5, the connection surface 151c connected to the driving surface 151a and the base surface 151b is formed flat, and a virtual straight line passing through the connection surface 151c is a virtual straight line passing through the base surface 151b. By being arranged perpendicular to the straight line, the second driving unit 150 can be controlled to rotate beyond a preset angle.

Referring to FIGS. 6 and 7, it shows a state in which the power applied to the driving source unit 110 is cut off. Unlike FIG. 4, the first magnetic region 145a formed on the first magnetic unit 145 is It may be formed as an N pole, and the second magnetic region 145b, which is formed relatively closer to the substrate portion 101 than the first magnetic region 145a on the first magnetic portion 145, may be formed as an S pole.

In other words, the second driving body 151 rotates clockwise with the longitudinal central axis of the driving control unit 153 as the rotational central axis AX.

As a result, the second driving body 151, specifically the expression unit 120 that maintains contact with the driving surface 151a, can move in the direction toward the driving source unit 110 (from the upper to the lower direction in FIG. 6). .

The information output device 100 according to an embodiment of the present invention has a drive source unit 110 surrounding the first drive unit 140, and as current is applied to the drive source unit 110, the first magnetic unit 145 The polarity changes, and power can be transmitted to the second driving unit 150 due to interaction with the second magnetic unit 155 provided in the second driving unit 150.

In addition, the polarity of the first magnetic unit 145 can be changed while the first driving unit 140 maintains its position by the current applied to the driving source unit 110, so the structure does not require a separate power transmission structure. It has a simplifying effect.

In addition, due to the curved portion 152 being formed in the area where the driving surface 151a and the base surface 151b formed in the second driving body 151 are connected, in the process of moving the expression portion 120, the expression portion ( 120) can maintain contact with the second driving body 151 and move smoothly to efficiently perform continuous and natural movement.
