１とから構成されている。[Prior Art] Conventionally, this type of device is shown in Fig. 2 (Japanese Patent Application No. 6
2-10496). In the figure, reference numeral 1 denotes a support stand, and this figure shows the case of a conveyor. A fabric 2, which is a workpiece, is supported on the conveyor 1. Reference numeral 3 denotes a laser beam emitting swing mirror for cutting or otherwise processing the fabric 2 by scanning and irradiating the fabric 2 with a laser beam two-dimensionally. Reference numeral 4 denotes a cover that is provided in the laser processing apparatus and forms a processing chamber 5 by covering the processing portion of the fabric 2 that is irradiated with laser light, and 6 provides a ventilation flow A onto the conveyor 1 in the processing chamber 5. This is an air blower installed in the processing chamber 5 to generate the gas. This blower device 6 includes an upstream blower 7 for taking in air B from outside the processing chamber 5 and discharging this air to generate a ventilation flow A, and an upstream blower 7 for sucking in this ventilation flow A and discharging it to the outside of the processing chamber 5. A downstream blower 8 is connected to the downstream blower 8 through a duct 9, and an exhaust fan 1 is connected to the downstream blower 8 for discharging the exhaust air from the downstream blower 8 to the outside via a duct 10.
It is composed of 1.

First, a ventilation flow A as shown in FIG. 2 is generated between the upstream side blower 7 and the downstream side blower 8 of the blower device 6 on the conveyor 1. This ventilation flow A needs to be generated as close to the surface of the fabric 2 as possible in order to immediately remove the smoke generated from the processed area. By operating the blower 7.8 and the exhaust fan 11, air B outside the processing chamber 5 → upstream fan - ventilation flow 8 downstream fan 8 → duct 9 - exhaust fan 11
-Duct 10-Air flow such as exhaust C is formed as shown by the arrow in FIG. When the laser processing device is operated under this condition and the laser beam is irradiated from the mirror 3 to the fabric 2 on the conveyor 1 while scanning it two-dimensionally, smoke is generated from the processed part of the fabric 2. The smoke is immediately removed from the processing section by the ventilation flow A, and is carried along with the air forming the air flow and discharged as exhaust C to the outside of the processing chamber 5.
