Abstract
A data printer wherein a slip is dropped in a guide chute and a serially operable print head is moved along the length of the slip to print a line of characters. A line feed device comprises a drive gear meshing with a driven gear carrying a feed roller for frictionally advancing the slip from one print line position, extending parallel to the length of the slip, to the next. The driven gear is moveable about the axis of the drive gear and is forced into frictional engagement with the slip by the rotational force imparted to the driven gear by the drive gear.
Claims1
A printer for slips or the like comprising
- means forming a vertical guideway into which a slip may be dropped,
- means forming a floor against which said slip may limit when dropped into said guideway,
- a pair of spaced freely rotatable guide rollers on one side of said guideway,
- a shaft on the side of said guideway opposite said guide rollers,
- a pair of spaced feed rollers on said shaft opposite respective ones of said guide rollers,
- said feed rollers having frictional drive surfaces thereon,
- a drive gear,
- means supporting said drive gear for rotation about an axis,
- a driven gear on said shaft meshing with said drive gear, said drive gear being,
- means for guiding said shaft about said axis of said drive gear,
- a printing device intermediate said guide rollers for printing a line of print on said slip substantially in line with the line of contact between said feed rollers and said slip,
- retainer means normally maintaining said shaft and said feed rollers away from said guide rollers, and
- means other than said drive gear for thereafter rotating said shaft in a direction to further engage said feed rollers with said slip and to line feed said slip past said printing device.
