Abstract

This application relates to an information output apparatus including at least one information output unit. The information output unit includes a coil unit connected to a power source to allow an electric current to flow therethrough and a base unit formed to accommodate the coil unit. The information output unit also includes an expression unit formed and arranged to allow a user to sense the expression unit and a driving unit arranged in the base unit to be separated from the coil unit. The driving unit is adjacent to the coil unit to be driven by the electric current flowing through the coil unit to perform an angular or rotational movement so as to move the expression unit in a first direction towards the coil unit and an opposite direction.

Claims (40)

1 . An information output apparatus comprising at least one information output unit,

wherein the information output unit comprises:

a coil unit connected to a power source to allow an electric current to flow therethrough;

a base unit formed to accommodate the coil unit;

an expression unit formed and arranged to allow a user to sense the expression unit;

a driving unit arranged in the base unit to be separated from the coil unit, the driving unit being adjacent to the coil unit to be driven by the electric current flowing through the coil unit to perform an angular or rotational movement so as to move the expression unit in a first direction towards the coil unit and an opposite direction;

a driving controller; and

a support unit arranged in the base unit and formed to have a length extending in a length direction, facing the expression unit,

wherein the coil unit is positioned around the support unit,

wherein the driving unit includes a first driving member, a second driving member and a separate area between the first driving member and the second driving member,

wherein the driving controller is arranged on at least one side surface of the first driving member and the second driving member,

wherein each of the first driving member and the second driving member includes a driving surface configured to support the expression unit in response to the driving unit performing the movement to move the expression unit,

wherein at least a moving region, having a surface spaced apart from the driving surfaces, is arranged in the separate area, and wherein the moving region is configured to be supported by an upper end of the support unit by contacting the upper end of the support unit,

wherein the driving unit is configured to perform the angular or rotational movement about the driving controller to drive the expression unit, and

wherein a central axis of the driving unit and a central axis of the driving controller are eccentric with respect to each other.

2 . The information output apparatus of claim 1 , wherein the driving unit includes a magnetic unit having regions of different polarities from each other.

3 . The information output apparatus of claim 1 , wherein the base unit further comprises a first accommodation unit configured to accommodate the coil unit and a second accommodation unit configured to accommodate the driving unit, the second accommodation unit being arranged adjacent to the first accommodation unit in the first direction.

4 . The information output apparatus of claim 3 , further comprising a boundary unit between the first accommodation unit and the second accommodation unit, the boundary unit configured to distinguish the first accommodation unit from the second accommodation unit.

5 . The information output apparatus of claim 1 , wherein the support unit is configured to support the driving unit when the driving unit is moved.

6 . The information output apparatus of claim 1 , further comprising a plurality of information output units,

wherein the plurality of information output units are arranged to be separated from one another in at least one direction.

7 . The information output apparatus of claim 1 , wherein the driving surfaces include a curved surface.

8 . The information output apparatus of claim 1 , wherein each of the first driving member and the second driving member has a rotator or disc shape.

9 . The information output apparatus of claim 8 , wherein each of the first driving member and the second driving member is configured to perform a rotational or angular movement.

10 . The information output apparatus of claim 9 , wherein in response to the first driving member and the second driving member performing the rotational or angular movement, driving power is configured to be provided to a supporting surface of the expression unit so that the expression unit effectively makes continuous movement.

11 . An information output apparatus comprising at least one information output unit,

wherein the information output unit comprises:

a coil unit connected to a power source to allow an electric current to flow therethrough;

a base unit formed to accommodate the coil unit;

an expression unit formed and arranged to allow a user to sense the expression unit;

a driving unit arranged in the base unit to be separated from the coil unit, the driving unit being adjacent to the coil unit to be driven by the electric current flowing through the coil unit to perform an angular or rotational movement so as to move the expression unit in a first direction towards the coil unit and an opposite direction;

a driving controller; and

a support unit arranged in the base unit and formed to have a length extending in a length direction, facing the expression unit,

wherein the coil unit is positioned around the support unit,

wherein the driving unit includes a first driving member, a second driving member and a separate area between the first driving member and the second driving member,

wherein the driving controller is arranged on at least one side surface of the first driving member and the second driving member,

wherein each of the first driving member and the second driving member includes a driving surface configured to support the expression unit in response to the driving unit performing the movement to move the expression unit,

wherein at least a moving region, having a surface spaced apart from the driving surfaces, is arranged in the separate area, and wherein the moving region is configured to be supported by an upper end of the support unit by contacting the upper end of the support unit,

wherein the driving unit is configured to perform the angular or rotational movement about the driving controller to drive the expression unit, and

wherein during the angular or rotational movement of the driving unit, the driving unit is further configured to provide upward and downward movements for causing the driving controller is configured to move up and down in response to the driving unit making an upward movement and a downward movement.
