IPC: H04N1/028
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To provide the driver for a micro scanner that can stably and efficiently drive the micro scanner over a long time, without causing mechanical stresses on the micro scanner. SOLUTION: This driver is provided with a drive signal generator 11, that generates a drive signal with a period equivalent to a mechanical resonance frequency of an optical head, which is reciprocated, turned and displaced by using a hinge as an axis, a driver 12 that applies a drive signal to a micro scanner 1 for exciting the optical head, and a soft start circuit 13 that allows the driver 12 to slowly increase the amplitude of the drive signal up to a prescribed amplitude at the start of driving the micro scanner. Thus, the driver drives the micro scanner with a signal, having a mechanical resonance frequency of the optical head and prevents an excess stress from exerting to the hinge by gradually increasing the amplitude of the drive signal at the start of the drive.
