WORD SPELLING MAIN UNIT, CHARACTER MODULE, AND WORD SPELLING SYSTEM

摘要

A word spelling main unit (100), a character module (200), and a word spelling system. The word spelling main unit (100) comprises a control module (110), and a detection portion (120) used for placing the cubic character module (200). The detection portion (120) is provided with a detection component (130). The detection component (130) is used for obtaining distribution of a detection mark (221) on the cubic character module (200). The control module (110) is used for identifying a character mark (211) on the cubic character module (200) according to the distribution of the detection mark (221). The character module (200) comprises a main body (201). The main body (201) is provided with at least one detection surface (220) and several character surfaces (210). Each of the character surface (210) is provided with a character mark (211). The at least one detection surface (220) is provided with at least one detection mark (221) having one-to-one correspondence to the character mark (211) on each of the several character surfaces (210). Multiple uses of one character module (200) are achieved, and thus, the number of character modules (200) required is generally reduced, the size and costs of the word spelling system are reduced, and a user can conveniently find corresponding characters.
