Abstract
An electronic apparatus for entering pattern data by activating a matrix array of keys with a finger. Pattern data may be input by drawing a pattern data on the keys. The time interval between depression of one key till the depression of a different key while a pattern data is being drawn, is measured by a register. The time interval being measured is symbolically displayed on a display section. Time data representing the time interval being measured is compared with a reference time interval in a comparator. When the coincidence of the two data being compared is detected, the pattern data that has been input by drawing the pattern is displayed on the display section.
