Title:
PATTERN FORMING APPARATUS AND LASER PROCESSING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/039242
Kind Code:
A2
Abstract:
(Object) To provide a pattern forming apparatus capable of ensuring the productivity of forming a pattern on a conveyed base material, and forming a pattern with good visibility while ensuring the mechanical strength of the base material. (Means of achieving the object) A pattern forming apparatus for forming a pattern by emitting a scanning light onto a plurality of base materials conveyed in a predetermined conveying direction, includes a plurality of emitting units including a first emitting unit and a second emitting unit, wherein the first emitting unit includes a first light source unit configured to emit a first laser light; a first conveying direction light scanning unit configured to scan the first laser light in the predetermined conveying direction; a first intersecting direction light scanning unit configured to scan a scanning light, scanned by the first conveying direction light scanning unit, in an intersecting direction that intersects the predetermined conveying direction; and a first light emitting unit configured to emit a first scanning light, scanned by the first intersecting direction light scanning unit, onto a base material among the plurality of base materials, wherein the second emitting unit includes a second light source unit configured to emit a second laser light; a second conveying direction light scanning unit configured to scan the second laser light in the predetermined conveying direction; a second intersecting direction light scanning unit configured to scan a scanning light, scanned by the second conveying direction light scanning unit, in the intersecting direction; and a second light emitting unit configured to emit a second scanning light, scanned by the second intersecting direction light scanning unit, onto another base material among the plurality of base materials, wherein the first light emitting unit emits the first scanning light onto the base material that is different from the another base material onto which the second light emitting unit emits the second scanning light, at a position different from a position where the second light emitting unit emits the second scanning light in the predetermined conveying direction.
