Abstract
A drive system for an optical imaging head assembly of a scanner includes a rack having a first side and a second side opposite the first side, the first side including a toothed surface and the second side including a guide surface, a pinion engaged with the toothed surface of the rack, and at least one guide member contacting the guide surface of the rack.
Claims45
A drive system for an optical imaging head assembly of a scanner, the drive system comprising:
- a rack having a first side and a second side opposite the first side, the first side including a toothed surface and the second side including a guide surface;
- a pinion engaged with the toothed surface of the rack;
- and
- at least one guide member contacting the guide surface of the rack.
A system for moving an optical imaging head assembly of a scanner, the system comprising:
- a rack having a first side and a second side opposite the first side, the first side including a toothed surface and the second side including a guide surface;
- a pinion engaging the toothed surface of the rack;
- and
- at least one guide member contacting the guide surface of the rack,
- wherein the pinion traverses the tooted surface of the rack and the at least one guide member slides along the guide surface of the rack.
A drive system for an optical imaging head assembly of a scanner, the drive system comprising:
- a rack having a first side and a second side opposite the first side, the first side including a toothed surface and the second side including a guide surface;
- means for moving the optical imaging head assembly along the toothed surface of the rack;
- and
- means for guiding the optical imaging head assembly along the guide surface of the rack.
A scanner, comprising:
- a housing;
- a platen supported by the housing;
- an optical imaging head assembly supported between the housing and the platen;
- and
- a drive system adapted to move the optical imaging head assembly relative to the housing and the platen,
- wherein rho drive system includes a rack having a first side including a toothed surface and a second side opposite the first side including a guide surface, a pinion engaged with the toothed surface of the rack, and at least one guide member contacting the guide surface of the rack.
A method of moving an optical imaging head assembly of a scanner, the method comprising:
- engaging a toothed surface provided on a first side of a rack with a pinion supported by the optical imaging head assembly;
- contacting a guide surface provided on a second side of the rack opposite the first side of the rack with at least one guide member supported by the optical imaging head assembly;
- and
- driving the pinion, including moving the optical imaging head assembly along the rack.
