Abstract

An end of scan switch for a scanning component which eliminates ovestsavel is shown in the Figure A scanning component PO, which may be an optical scanning carriage, or a scanning lens, for a copier, IS being driven in the indicated scan direction via a drive cable 12 Cable 12 slides axially within an end of scan switch assembly 14 . Assembly 14 includes a cam 16 which 1s maintained in the indicated position vis-a-vis stationary switch 11 during scan by compression springs 18,18' When the scan component 10 comes to the end of scan position [ encountering hard stop 20 ) cable 12 continues to move axially through assembly 14 moving cam 16 relative to switch 17 Switch 17 is pressed downward by the cam end until the switch IS turned off removing power to the drive motor. A separate circuit is used to reverse and apply power to the drive motor following motor turnoff
