Abstract
This application relates to an information output device using a unit block module. Due to the use of the unit block module, apparatus of various sizes may be simply constructed and/or designed, durability and user convenience may be improved, waterproof properties are provided, power consumption is minimized, and an operation error of a driving module may be minimized. And, when a pin is driven down, the pin may be driven down more easily by the attraction of a magnetic material and a magnetic member.
