APPARATUS FOR INPUTTING DIGITAL DATA USING LASER

摘要

PURPOSE: A digital input device using a laser is provided to use the laser and conveniently input various data in various input panel without a size and a type of a data input panel. CONSTITUTION: A laser emitting unit(100) examines a laser beam with a date input panel(200). A first laser receiving unit and a second receiving unit(300-2) receives laser light reflected from a fixed location of the data input panel. A data input controller(500) determines a reflection location of the laser light in the data input panel from a time difference between examining time of the laser light and light-receiving time of laser light which receives light from a first laser light receiving unit and a second laser light receiving unit and recognizes an inputted data based on the reflection location.
