| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a transmitter by which an indicating laser beam is emitted toward the specified region and transmission data is transmitted and received. <P>SOLUTION: A laser pointer 4 has a laser diode 45 emitting the indicating laser beam toward the specified region and an LD (Laser Diode) driver 44 modulating the laser beam emitted by the laser diode 45 based on the specified transmission data. The LD driver 44 superimposes a modulation signal corresponding to the transmission data on a bias current to supply a driving current to the laser diode 45. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
