  • Carrier (50) on which the drive units (60, 70) are joined consists of a lower plate (52), an upper plate (51), and a rear plate (53) which enables the connection of said plates (51 , 52) by lying between them.
  • Primary and secondary drive units (60, 70) are positioned between upper and lower plates (51 , 52), and connect over the mounting area (54, 55) through joints (62, 72) so that they can rotate on mounting axes (a1 , a2).
  • Shafts (63, 73) that are positioned inside the drive units (60, 70) pass through the bodies (61 , 71 ) of drive units (60, 70) and extend out on both sides of the bodies (61 , 71).

  • movement mechanism (40) is seen with the laser head (30) at different positions. According to Figure 8 and 9, when shaft (63, 73) is forwarded by only one of the drive units (60,70), laser head (30) approaches the other drive unit (60, 70), and when it is forwarded by two of them, it gets away from the carrier (50) as seen in Figure 10.
  • position of the laser head (30) can be changed within a certain work area by forwarding the shafts (63, 73) at different amounts.
