Abstract
A scanning system that accurately positions a moving carriage assembly in two directions relative to a platen. Such a scanning system includes a frame that has a registration member that extends in the Y direction, and a platen whose plane is normal to the Z direction and which is attached to the frame. The platen receives a substrate in a predetermined position relative to the registration member. The scanning system further includes a base that has a first and second tilted surfaces that extend in the Y direction, and a moving carriage assembly that is disposed between the platen and the base. The moving carriage assembly includes a housing, at least one button connected to the housing, and first and second biased pivot arms with first and second rollers that ride on the first and second tilted surfaces. The biased pivot arms push the housing against the tilted surfaces such that the button contacts the platen and the registration member. Furthermore, the moving scan imaging system also includes a motion inducing system for moving the moving carriage assembly relative to the platen. Beneficially, when the motion inducing system moves the moving carriage assembly the first and second rollers slide and roll along on the tilted surfaces and therefore bias the button toward the registration member.
