PROBLEM TO BE SOLVED: To reduce space necessary for adjusting the rotation of a light source unit. SOLUTION: In a light source unit 10, the plural beam P(n) of a lead frame 23 are protruded outside from the inside of a package 20. The protruding directions of these leads P(n) is the optical axial direction of a laser lean emitted from the light source unit 10. The leads P(n) are protruded only from the rear wall 213 of the package 20. Thus, when the light source unit 10 is rotated and adjusted around an optical axis, the necessity of securing extra space is eliminated to prevent the interference of the plural leads P(n) with other portions. Therefore, space necessary for adjusting the rotation of the light source unit is reduced. |
