LASER MARKER

Document Type and Number:

WIPO Patent Application WO/2020/158144

Kind Code:

A1

Abstract:

Provided is a laser marker where positioning of a laser oscillation unit is carried out with high precision relative to a scanning unit into which an expander of the laser oscillation unit is inserted. A laser marker 1 comprises; a laser oscillation unit 12; a scanning unit which scans laser light of the laser oscillation unit 12; and a base 10 which is provided to the scanning unit and has an insertion part into which an expander 82 of the laser oscillation unit 12 is inserted when the laser oscillation unit 12 is mounted. The base 10 has a downstream-side first guide section 58, and a restricting section 62 which restricts sliding of the laser oscillation unit 12 on the base 10. The laser oscillation unit 12 has: a downstream-side second guide section 92 which defines a mounting direction MD of the laser oscillation unit 12 by engaging the downstream-side first guide section 58 of the base 10; and an abutting section 94 which abuts against the restricting section 62 of the base 10 when the laser oscillation unit 12 is mounted to the scanning unit.
