Abstract
A printer for printing data on an original slip and on a copy slip in which both are dropped into a guide chute. Feed and pinch rollers having a higher degree of friction that the friction between the slips tend to drive both slips along the chute and past an ink jet printer. However, a brake initially prevents rotation of the pinch roller and thus retains one of the slips while the other slip is advanced past the printer, at which time the brake is released to enable the feed roller to advance the remaining slip past the printer.
Claims9
A printer for printing data on each of a pair of superimposed record mediums comprising the combination of
- a printing device,
- means for guiding said mediums past said printing device,
- a feed roller,
- means for rotating said feed roller,
- a pinch roller for pressing said mediums into engagement with each other and with said feed roller, said rollers having greater frictional gripping characteristics than the frictional gripping characteristics of said mediums with each other,
- a braking device coupled to said pinch roller,
- means for (preventing) enabling said braking device whereby to prevent rotation of said pinch roller whereby (prevent) to enable said feed roller to advance one only of said mediums past said printing device, and
- means for thereafter (enabling) disabling said braking device to enable said feed roller to advance the other of said mediums past said printing device.
A printer for printing data on each of a pair of record mediums comprising the combination of
- a printing device,
- means for guiding said mediums past said printing device,
- a feed roller,
- means for rotating said feed roller,
- a pinch roller adapted to press said mediums into engagement with each other and with said feed roller,
- said rollers having greater frictional gripping characteristics than the frictional gripping characteristic of said mediums with each other,
- means for holding said pinch roller out of engagement with said mediums,
- means operable by said holding means for preventing rotation of said pinch roller, and
- means responsive to a predetermined movement of one of said mediums past said printing device for disabling said rotation preventing means.
A printer for printing data on each of a pair of superimposed record mediums comprising the combination of
- a printing device,
- a chute for guiding said mediums past said printing device,
- said chute having a first wall,
- a feed roller,
- means for rotating said feed roller,
- a pinch roller for yieldably pressing said mediums into frictional gripping engagement with said feed roller,
- the frictional engagement of said rollers with respective ones of said mediums being greater than the frictional engagement said mediums with each other,
- means for braking said pinch roller whereby to enable said feed roller to advance one only of said mediums toward one end of said chute and past said printing device,
- means for thereafter releasing said braking means whereby to enable said feed roller to advance the other of said mediums toward said one end of said chute and past said printing device,
- said chute having a second wall at said one end of said chute,
- said second wall being located in a plane spaced rearwardly from the plane of said first wall and inclined rearwardly relative to said first wall, and
- means for deflecting a said medium toward said second wall after passing said first wall.
