Summary: | PROBLEM TO BE SOLVED: To provide an optical scanner suitable for downsizing. SOLUTION: This optical scanner has an annular semiconductor laser 1 which emits laser beam excited by resonance when receiving a laser beam, a columnar body 11 which is arranged with its outer peripheral surface 12 in a hollow part of the semiconductor laser 1 so as to face the inner peripheral surface 4 of the semiconductor laser 1 and is rotated at a prescribed speed around the central axis and a resonator 13 which is disposed integrally at the columnar body 11 and is arranged with a reflection end face 14 for reflecting the laser beam from the semiconductor laser 1 and making the laser beam incident on the inner peripheral surface 4 of the semiconductor laser 1 at the outer peripheral surface 12 of the columnar body 11. |
