Description

  The present invention relates to a laser marking device that performs marking using line light from a laser.

In the laser marking device provided conventionally, a carrying band is attached to the main body case of the laser marking device so that it can be easily carried (Patent Document 1).
JP 2000-298022 A (FIG. 1)

  In the above-mentioned laser marking device, if the laser marking device is accidentally dropped from the upper surface side onto the ground, the carrying band attached to the main body case is rotated by its own weight so that it can rotate in the horizontal direction. Then, it is located on the ground side and collides with the ground from this carrying band. At this time, if the carrying band is made of, for example, a soft leather, the band itself will bend, so that it is not possible to protect the laser marking device by buffering the impact at the time of dropping. In addition, if the carrying band is made of a hard metal handle, for example, the shock that occurs when the tip of the band hits the ground is transmitted directly to the part that supports the band so that it can be shocked. Without being transmitted to the laser marking device, the laser marking device cannot be protected in the same manner as a leather band. As described above, when the laser marking device falls, if the shock cannot be buffered, there is a problem that the accuracy of the optical system is lowered and the laser emission direction is shifted.

  The present invention has been made in view of the above points, and its purpose is to suppress a drop in the accuracy of the optical system by buffering the impact when the laser marking device is accidentally dropped. It is to provide a laser marking device that can.
