As an optional embodiment, the second direction may be a direction orthogonal to the first direction, and may be, for example, an X-axis direction based on FIGS. 25 and 26 .

For convenience of description, the first direction and the second direction will be used as having the same meaning even when described below.

The second region 1235B may be formed to correspond to the protrusion 1215 when the drive expression unit 1210 moves in the second direction after moving in the first direction.

That is, when the driving expression unit 1210 rotates, the protruding portion 1215 rises from the first area 1235A and rotates at a predetermined angle to be disposed in the second area 1235B.

The second region 1235B may have a shape corresponding to a state in which the protruding portion 1215 is rotated and disposed, for example, may have a curved surface.

In addition, the second area 1235B has an appropriate width to facilitate movement when the drive expression unit 1210 moves back in the second direction and then descends in a direction opposite to the first direction, for example, rotates. can

Also, the second area 1235B may have a shape similar to a state in which the first area 1235A is rotated.

After the driving expression unit 1210 is disposed in the second region 1235B, the base part 1230 may include a locking step 1236 so as to maintain the same state. The locking jaw 1236 includes an upper surface 1236A and a side surface 1236B, and the upper surface 1236A and the side surface 1236B of the locking jaw 1236 are connected, and the protrusion 1215 according to the motion of the driving expression unit 1210 ) may correspond to the fixing part 1215B.

That is, in the state shown in FIG. 26, the fixing part 1215B of the protruding part 1215 of the driving expression part 1210 is moved by the side surface 1236B of the locking jaw 1236 when no external force is transmitted, For example, rotational movement may be limited.

In addition, when the drive expression unit 1210 moves and the protrusion 1215 corresponds to the second area 1235B of the driving groove 1235, the fixing part 1215B of the protrusion 1215 is the upper surface of the locking jaw 1236 ( 1236A) may restrict movement.

27A to 27D are diagrams for explaining the operation of the output unit of FIG. 25;

The operation of the information output device will be described with reference to FIGS. 27A to 27D in order.

Referring to FIG. 27A , a state in which the drive expression unit 1210 has descended from the state of FIG. 27A , that is, a state in which it does not protrude, may be a state before the user manipulates the input pen 100 . Alternatively, it may show a state after initialization is performed using a reset member.

In this state, when the user manipulates the input pen 100, for example, when the input pen 100 is moved to be adjacent to the drive expression unit 1210, the drive expression unit 1210 generates an upward force by the magnetic field. and can be rotated in the MD1 direction by the protrusion 1215 and the driving groove 1235.

For example, when a force in the first direction is transmitted to the driving expression unit 1210 by a magnetic field generated between the input pen 100 and the driving expression unit 1210, that is, a repulsive force acts on the input pen 100. The protrusion 1215 through the curved surface of the side part 1215A of the lower surface protrusion 1215 and the curved surface of the second area 1235B of the driving groove 1235 or through the curved surface of the first area 1235A and the second area 1235B. ) is disposed as the second area 1235B, the drive expression unit 1210 can be easily rotated.

Referring to FIG. 27B through this, a state in which the driving expression unit 1210 rotates in the MD1 direction of FIG. 27A in the state of FIG. 27A is illustrated.

Through this, the driving expression unit 1210 may rise higher than that shown in FIG. 27A described above, and the driving expression unit 1210 may have a protruding shape.

Then, referring to FIG. 27C , a state in which the driving expression unit 1210 moves in the ND direction of FIG. 27B is illustrated.

That is, the drive expression unit 1210 may move in a direction opposite to the first direction from the state of FIG. 27B, for example, move downward to have the state of FIG. 27C.

In addition, as an optional embodiment, the driving expression unit 1210 may move in the state of FIG. 27c while descending due to gravity even if no additional force is applied in the state of FIG. 27b.

Also, at this time, as long as a predetermined force in the first direction is not transmitted to the driving expression unit 1210, the motion of the driving expression unit 1210 can be controlled. For example, the movement or rotational movement of the drive expression unit 1210 in the second direction may be controlled by the side surface 1236B of the locking protrusion 1236 of the base portion 1230 .

As an optional embodiment, the side surface 1236B of the locking jaw 1236 may have a flat surface.

In this state, the user can sense the protrusion of the driving expression unit 1210 of the output unit IU8, and can sense it visually or tactilely, for example. Also, as an optional embodiment, this protruding state can be maintained.

You can then proceed with the initialization process.

This initialization process may be performed through the reset member IMGU. The reset member IMGU may be formed to react with the drive expression unit 1210 . For example, the reset member IMGU may include a magnetic force member to generate a magnetic field, and may include a permanent magnet as a specific example.

The reset member IMGU may generate a magnetic field, and for example, the reset member IMGU may be formed such that an attractive or repulsive force acts on the drive expression unit 1210 . To this end, the polarity and arrangement direction of the reset member IMGU may be controlled.

The arrangement and operation of the reset member IMGU may be determined in various ways, and the specific details thereof are the same as described above.

The driving expression unit 1210 can move upward by the magnetic field generated between the reset member IMGU and the driving expression unit 1210, and rotate through the configuration of the driving groove 1235 and the protrusion 1215, As shown in FIG. 27D , the driving expression unit 1210 may maintain a non-protruding state.

In the protruding feedback-based smart tablet of this embodiment, one or more, for example, a plurality of output units arranged to be spaced apart from each other in the expression area may be disposed.

Such an output unit may protrude in response to a user's input, for example, in response to an input pen manipulated by a user. As a specific example, the moving part of each output unit may move by a mutual magnetic field with the input pen.

The expression unit of the output unit can be moved by a moving unit, and can protrude as a specific example. A user can easily detect a shape input using an input pen by detecting the expression unit of the protruding output unit through visual or tactile senses. For example, in the case of a disabled user with weak or no eyesight, the protruding shape of the expression part of the output units can be easily grasped with respect to characters or pictures input through an input pen.

As an optional embodiment, even if the input pen is removed, the moving part supporting the expression part can stay at a constant position so that the protruding expression part can be sensed for a period of time desired by the user.

In addition, the user can easily perform an input operation using the user's input pen by initializing using the reset member at a desired time, for example, by lowering the protruding expression unit back to its original state.

In addition, in detail, the drive expression unit can easily move in a first direction by a magnetic field, for example, can ascend, and can move in a second direction, for example, rotate in a clockwise direction by the protrusions and drive grooves of the drive expression unit. there is. In addition, rotational motion of the protruding part may be restricted while the fixing part of the protrusion is supported by the locking jaw of the driving groove. Through this, it is possible to easily maintain a state in which the protrusion of the drive expression unit is lowered, for example, an off state.

Then, when a force is applied to the driving expression unit in a direction opposite to the first direction, a rotational movement, for example, can be rotated in a counterclockwise direction by the protruding portion and the driving groove of the driving expression unit, and a continuous force is applied or force Even if this is removed, the drive expression unit may move in a direction opposite to the first direction, for example, descend. In addition, while the fixing part of the protrusion is supported by the locking jaw of the driving groove, further rotational motion may be restricted. And the protruding state of the drive expression unit can be maintained, for example, it can be maintained in an on state.

Through this, it is possible to easily switch and maintain the on and off states of the driving expression unit, reduce the power consumption for motion of the driving expression unit, and improve the overall energy efficiency of the output unit.
