Claims
- 1. In a printing device having printing means, drive means for said printing means, and means for incrementally, longitudinally advancing an inked ribbon relative to said printing means, the improvement in said ribbon advancing means which comprises a continuously rotating member driven by said drive means; a transmitting member displaceable between a first rest position and a second position; first coupling means selectively operably engaging said transmitting member and said rotating member for the selective displacement of said transmitting member between said first and second positions in response to the rotation of said rotating member; spring means coupled to said transmitting member for the storage of energy during the displacement thereof between said first and second positions; means disengaging said transmitting member and said rotating member at said second position to release said transmitting member for return to said first position in response to the energy stored in said spring means; ribbon engaging means; and second coupling means operably engaging said transmitting means and said ribbon engaging means during said displacement of said transmitting member for operative displacement of said ribbon advancing means.
- 2. A printing device as recited in claim 1, wherein said means coupling said transmitting member and said ribbon advancing means includes a pivotably mounted lever having a pair of arms, a first of said arms operatively engaging said transmitting member for the pivotable displacement of said lever between first and second positions corresponding to the first and second positions of said transmitting member, said second arm being operatively coupled to said ribbon advancing means; and second spring means coupled to said lever for biasing said lever to its first position.
- 3. A printing device as recited in claim 2, including ribbon shift means for selectively laterally displacing said ribbon relative to said printing device, said ribbon shift means including ribbon support means pivotably mounted for displacement between first and second positions representative of two laterally shifted positions of said ribbon; means biasing said ribbon support means in said second position; detent means coupled to said ribbon support means for releasably retaining said ribbon support means at said first position; means for the selective displacement of said detent means to release said ribbon support means for displacement from its first to its second position; and means coupling said transmitting member and said ribbon support means, when released, for displacing said ribbon support means from its second to its first position at which it is captured by said detent means during the displacement of said transmission member.
- 4. A printing device as recited in claim 3, wherein said means for selectively releasing said detent means includes solenoid means.
- 5. A printing device as recited in claim 4, wherein said printing device is a flying printer having a continuously rotating print drum and a rotating shaft supporting said print drum, said rotating member being mounted on said print drum shaft for rotation therewith.
- 6. A printing device as recited in claim 3, wherein said second coupling means operably engages said transmitting means and said ribbon engaging means during the displacement of said transmitting means from its second to its first position.
- 7. A printing device as recited in claim 3, wherein said means coupling said transmitting member and said ribbon support means is adapted to displace said ribbon support means, when released, from its second to its first position during the displacement of such transmission member from its first to its second position.
- 8. A printing device having printing means, continuously rotating drive means for said printing means, and means for supporting an inked ribbon in registration with said printing means, the improvement in said printing device which comprises a continuously rotating member driven by said drive means; a transmitting member displaceable between a first rest position and a second position; first coupling means selectively operably engaging said transmitting member and said rotating member for the selective displacement of said transmitting member between said first and second positions in response to the rotation of said rotating member; first spring means coupled to said transmitting member for the storage of energy during the displacement thereof between said first and second positions; means disengaging said transmitting member and said rotating member at said second position to release said transmitting member for return to said first position in response to the energy stored in said spring means; means pivotably mounting said ribbon support means for displacement between first and second positions representative of two laterally shifted positions of said ribbon; second spring means biasing said ribbon support means in its second position; detent means coupled to said ribbon support means for releasably retaining said ribbon support means at its first position; means for selectively releasing said detent means to release said ribbon support means for displacement from its first to its second position; and means coupling said transmitting member and said ribbon support means, when released, for displacing said ribbon support means from its second to its first position at which it is captured by said detent means during the displacement of said transmission member.
- 9. A printing device as recited in claim 8, wherein said means for selectively releasing said detent means includes solinoid means.
- 10. A printing device as recited in claim 8, wherein said printing device is a flying printer having a continuously rotating print drum and a rotating shaft supporting said print drum, said rotating member being mounted on said print drum shaft for rotation therewith.
- 11. A printing device as recited in claim 8, wherein said first and second positions of said ribbon support means present regions of different colored inks into registration with said printing means.
