Abstract
This application relates to an information output apparatus. In one aspect, the apparatus includes a casing including an expression surface and an expression hole formed in the expression surface. The apparatus also includes a protrusion provided to reciprocate such that at least a part thereof protrudes out of the expression hole and information is expressed on the expression surface. The apparatus also includes a driving module located inside the casing and connected to the protrusion to move the protrusion.
Claims14
An information output apparatus comprising:
- a casing comprising an expression surface and an expression hole formed in the expression surface;
- a protrusion configured to cause information to be expressed on the expression surface based on at least a part of the protrusion protruding from the expression hole of the expression surface;
- a driving module located inside the casing and connected to the protrusion to move the protrusion;
- and
- a skin module located facing the expression surface, the skin module comprising a film having a first surface and a second surface opposite to the first surface, the first surface facing the expression surface,
- wherein the casing comprises an active region in which the expression hole and the expression surface are located, and a non-active region at an edge of the active region,
- wherein the film is not in contact with the expression surface so as to always maintain a separated state from the expression surface in the active region, and
- wherein a separation distance is defined between the first surface of the film and the expression surface, and wherein the separation distance is equal to or greater than a maximum protruding height of the protrusion measured from the expression surface.
