LIQUID CRYSTAL MASK AND LIQUID CRYSTAL TYPE LASER MARKER AND CARVING METHOD THEREBY

摘要

PURPOSE: A liquid crystal typed laser marker is provided to indicate a design on a liquid crystal mask that has plural pixels and to carve laser light from the liquid crystal mask by irradiating to an art craft. CONSTITUTION: When dividing the design in a length direction, the laser maker carves the design using the liquid crystal mask(2a) that makes big one side pixel of the originated side to one of an upper and lower direction or a right and left direction. A controller(11) indicates each block(1) on a liquid crystal mask(2a) and irradiates laser light on the liquid crystal mask by outputting a command to each driving unit(32,31) of the first biasing devices(23X)(23Y). The second biasing devices(27X)(27Y) are controlled by the controller to face a carving area corresponding to the block that indicates a carving position.
