BUILDING BLOCK TYPE SPELLING HOST, CHARACTER MODULE AND SPELLING SYSTEM

摘要

A building block type character module comprises at least two character marks, a first module interface and a second module interface. The first module interface includes a direction detection interface, and the second module interface includes a direction transfer interface. The direction transfer interface includes at least two direction transfer contacts each electrically connected with a direction identification element. The direction detection interface is used to detect the parameters of the direction transfer contact. The building block type spelling system including the building block type character module and the building block type spelling host can calculate the character mark of each of the building block type character modules corresponding to the side of the building block type spelling host toward the user, and read the spelling sentence. The required number of the building block type character modules is small and easy to be found.
