Title: Image scanner
Inventor: KARASAWA HIROYUKI
IPC: G02B26/10
Filed: 2002-07-31
Abstract: <P>PROBLEM TO BE SOLVED: To obtain rotation which is immune to noise and has little jitters even when signal transmission is necessary between a scanner motor and a driving circuit by separately constituting the scanner motor and the driving circuit for driving the scanner motor in order to rotate a polygon mirror of large mass at a low speed.  <P>SOLUTION: An FG signal generated by an FG (frequency generator) coil 138 of a motor body 132 for rotating the polygon mirror is digitalized by a signal processor 140 and the digital signal is transmitted to a driving circuit substrate 130. A driving circuit 150 decodes the transmitted signal and generates a driving signal to be supplied to the motor body 132 as a speed feedback signal and transmits the signal. The FG signal of the small amplitude is digitalized on the occasion of the signal transmission and therefore the SN ratio (signal-to-noise ratio) is increased and even if the noise is included therein, the driving signal having no jitters can be generated. Accordingly, the jitters in the rotation of the polygon mirror 114 are eliminated.  <P>COPYRIGHT: (C)2004,JPO
