1. A laser processing apparatus comprising:
a laser irradiation unit;
a conveying device that conveys a plate material along a conveying direction;
a drive unit that moves the laser irradiation unit above the plate material;
a dust collecting unit that moves below the plate material and follows the laser irradiation unit such that the dust collecting unit is disposed directly below the laser irradiation unit; and
a roller that is provided at an opening of the dust collecting unit and is rotatable around an axis parallel to a width direction orthogonal or substantially orthogonal to the conveying direction,
wherein the laser processing apparatus further comprising a driving mechanism that rotates the roller in synchronization with a conveying operation of the plate material by the conveying device,
a non-contact support portion is provided at the opening, and the non-contact support portion suctions a lower surface of the plate material toward a suction surface and supports the plate material without bringing the lower surface of the plate material and the suction surface into contact with each other,
the opening includes an upstream-side opening edge extending along the width direction, and a downstream-side opening edge extending along the width direction on a downstream side of the upstream-side opening edge in the conveying direction in a plan view, and
the roller includes a plurality of rollers, and the non-contact support portion includes a plurality of non-contact support portions, and one or more of the rollers and one or more of the non-contact support portions are provided alternately along the width direction at each of the upstream-side opening edge and the downstream-side opening edge.
