Laser marker

A laser marker comprising:

• a laser light source;
• a scanner configured to two-dimensionally scan laser light, from the laser light source, outward, the scanner having a first scanning mirror and a second scanning mirror;
• a first housing accommodating the laser light source;
• a second housing connected to the first housing and accommodating the scanner, the second housing being rotatable with respect to the first housing;
• a sensor configured to output a detection signal, the detection signal indicating a rotation position of the second housing with respect to the first housing;
• and
• a controller configured to:
• determine, based on the detection signal from the sensor, whether a sensor state is a first state or a second state, the first state indicating that the rotation position of the second housing is either in a first rotation position or in a second rotation position, the second state indicating that the rotation position of the second housing is between the first rotation position and the second rotation position, the second rotation position being perpendicular to the first rotation position;
• control the laser light source to emit the laser light outward when determined that the sensor state is in the first state;
• and
• control the laser light source not to emit the laser light outward when determined that the sensor state is in the second state.
