Claims (11)

1. In a printing device having printing means, drive means for said printing means and means for incrementally, longitudinally advancing paper relative to said printing means, the improvement in said paper 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 operatively 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, said first coupling means including a first lever mounted on said transmitting member for pivotable displacement into and out of operative engagement with said rotating member; a first spring means biasing said first lever into said operative engagement; first detent means mounted on said transmitting means for releasably retaining said first lever out of operative engagement with said rotating member; and selective releasing means coupled to said first detent means for selectively releasing said first detent means to permit the displacement of said first lever into operative engagement with said rotating member for the displacement of said transmitting member; second 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 second spring means; paper engaging means for the displacement of said paper; and second coupling means operatively engaging said transmitting means and said paper engaging means during said displacement from said second to said first position for operative displacement of said paper engaging means.
2. A printing device as recited in claim 1, wherein said disengagement means includes a fixed member in the path of said first lever during the displacement of said transmitting member from said first to said second position for pivotably displacing said first lever out of operative engagement with said rotating member and into locking engagement with said first detent means at said second position.
3. A printing device as recited in claim 2, wherein said first lever includes an inclined camming surface for engagement against said fixed member.
4. A printing device as recited in claim 3, wherein said driving means includes a drive shaft, said drive shaft defining said disengaging means fixed member.
5. A printing device as recited in claim 1, wherein said rotating member is a gear, said first lever being formed with a portion defining a rack for cooperation with said gear for the displacement of said transmitting member.
6. A printing device as recited in claim 1, wherein said selective releasing means includes solenoid means for the selective displacement of said first detent means.
7. A printing device as recited in claim 1, 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.
8. A printing device as recited in claim 1, including an inked ribbon, ribbon engaging means for incrementally, longitudinally advancing said ribbon relative to said printing means; and means operatively coupling said ribbon advancing means and said transmitting member for the longitudinal displacement of said ribbon in response to the displacement of said transmitting member from its second to its first position.
9. A printing device as recited in claim 8, wherein said means coupling said transmitting member and said ribbon advancing means includes a second pivotably mounted lever having a pair of arms, a first of said arms operatively engaging said transmitting member for the pivotable displacement of said second 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 spring means coupled to said second lever for biasing said second lever to its first position.
10. A printing device as recited in claim 8, 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; second 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 second 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 for displacing said ribbon support means from its second to its first position at which it is captured by said second detent means during the displacement of said transmission member from its first to its second position.
11. A printing device as recited in claim 10, wherein said means for selectively releasing said second detent means includes second solenoid means.
