Abstract

Provided is an information output apparatus including one or more information output units, wherein each information output unit includes a coil arranged to be connected to a power source, such that a current flows in the coil; a base unit configured to accommodate the coil; and a driving indicator, which is arranged in the base unit to be apart from and close to the coil to be driven by a current flowing in the coil and is configured to move in a first direction toward the coil and a direction opposite thereto to rotate while being connected to the base unit and to move in a second direction crossing the first direction to be recognized by a user.

First claim

The invention claimed is:

1. An information output apparatus comprising one or more information output units,
wherein each information output unit comprises:
a coil arranged to be connected to a power source, such that a current flows in the coil;
a base to accommodate the coil; and
a driving indicator, which is arranged in the base to be apart from and close to the coil to be driven by a current flowing in the coil and is configured to move in a first direction toward the coil and a direction opposite thereto to rotate while being connected to the base and to move in a second direction crossing the first direction to be recognized by a user,
wherein the base includes a partitioned space;
wherein both the coil and the driving indicator are each arranged in the partitioned space in the base to spatially separate the coil and the driving indicator to prevent the coil from interfering with the driving indicator; and
wherein the driving indicator comprises a first magnetic portion and a second magnetic portion having different polarities from each other.

2. The information output apparatus of claim 1 , wherein the movement of the driving indicator in the second direction comprises a rotational movement.

3. The information output apparatus of claim 1 , wherein the base comprises a first accommodator to accommodate the driving indicator and a second accommodator to accommodate the coil.

4. The information output apparatus of claim 3 , wherein the first accommodator and the second accommodator of the base are arranged apart from each other.

5. The information output apparatus of claim 1 , wherein:
the driving indicator comprises a main body region and a protrusion protruding from a side surface of the main body region, and
the movement of the driving indicator is controlled through the protrusion.

6. The information output apparatus of claim 5 , wherein the protrusion comprises a curved surface.

7. The information output apparatus of claim 5 , wherein the base comprises a driving groove corresponding to the protrusion of the driving indicator.

8. The information output apparatus of claim 7 , wherein the driving groove comprises a curved surface.

9. The information output apparatus of claim 7 , wherein the base comprises a locking hook for restricting the movement of the protrusion in the driving groove.

10. The information output apparatus of claim 1 , wherein the one or more information output units comprises a plurality of information output units which are arranged to be apart from one another in one direction or another direction different therefrom.

11. An information output apparatus comprising one or more information output units,
wherein each information output unit comprises:
a coil arranged to be connected to a power source, such that a current flows in the coil;
a base to accommodate the coil; and
a driving indicator, which is arranged in the base to be apart from and close to the coil to be driven by a current flowing in the coil, is configured to move in a first direction toward the coil and a direction opposite thereto to rotate while being connected to the base and to move in a second direction crossing the first direction to be recognized by a user, and is configured to induce therein a magnetic field having a magnetic axis-wise direction eccentric in one direction,
wherein the base includes a partitioned space;
wherein both the coil and the driving indicator are each arranged in the partitioned space in the base to spatially separate the coil and the driving indicator to prevent the coil from interfering with the driving indicator; and
wherein the driving indicator comprises a first magnetic portion and a second magnetic portion having different polarities from each other.

12. The information output apparatus of claim 11 , wherein the driving indicator comprises a magnetic body adjacent to the magnetic portion.

13. The information output apparatus of claim 11 , wherein the magnetic portion is tilted with the lengthwise direction of the driving indicator to have a magnetic axis-wise direction eccentric with the driving indicator.

14. The information output apparatus of claim 11 , wherein the magnetic portion has a length extended to reach a center point of the driving indicator in the lengthwise direction.

15. The information output apparatus of claim 11 , wherein the movement of the driving indicator in the second direction comprises a rotational movement.

16. The information output apparatus of claim 11 , wherein:
the driving indicator comprises a main body region and a protrusion protruding from a side surface of the main body region, and
the movement of the driving indicator is controlled through the protrusion.

17. The information output apparatus of claim 16 , wherein the base comprises a driving groove corresponding to the protrusion of the driving indicator.

18. The information output apparatus of claim 11 , wherein the one or more information output units comprises a plurality of information output units which are arranged to be apart from one another in one direction or another direction different therefrom.
