Information output apparatus

An information output apparatus comprising:

• an expression surface including a plurality of expression holes;
• and
• a plurality of output modules,
• wherein each of the plurality of output modules includes:
• a pin configured to protrude to the expression surface through the respective plurality of expression holes and express a protrusion signal on the expression surface;
• a first movement assembly located at an inner side of the expression surface and configured such that at least a portion of the first movement assembly moves in a first direction when an electric signal is applied thereto, wherein the first movement assembly includes a magnet;
• a second movement assembly located at the inner side of the expression surface and configured to move in a second direction different from the first direction in cooperation with a motion of the first movement assembly and drive each of the plurality of pins such that each of the plurality of pins protrudes to the expression surface through each of the expression holes;
• and
• a plurality of magnetic bodies which face the first movement assembly,
• wherein each of the plurality of magnetic bodies is spaced apart from the magnet.
