Abstract
A galvano scanner system has a galvano scanner and a scanner driver for driving the scanner, wherein a microcomputer for generating commands in which digital data representing a drive pattern of the scanner is written is mounted in the scanner driver. The microcomputer for generating commands is actuated by an external or internal trigger signal, and the digital data of the drive pattern is sequentially output. The output data is converted to an analog signal in a DA converter, and a drive control circuit generates a drive signal of the scanner on the basis of the analog signal to drive the galvano scanner. A system that can optimally drive a galvano scanner can be achieved with a small inexpensive system configuration.
