An alarm equipment providing vocabulary operating at random interval is provided to maximize the memorizing effect of words by showing word information at an irregular time interval. A random time interval calculator(107) calculates irregular time interval, and a memory unit(104) stores word information groups that are a memorizing target. A control unit(101) provides the word information to a user based on the random selection or sequential order in the word information groups of the memory unit. According to the control from the control unit, a display unit(103) displays the word information. |
