Abstract
Electrically activated margin setting and clearing is combined with a margin position memory device in a page printer. Readout of the memory to sense the set margin positions in relation to carriage position provides electrical signals to limit carriage travel to the desired length of writing line. A specific semihermaphroditic dashpot having nesting tubular pistons is provided to snub carriage return operation. The dashpot can be used as part of a mechanical left margin structure.

Claims (6)
1. In a page printer of the type having a mechanism-supporting framework and a printing means supported by a carriage for positioning along a writing line, the combination including: A. at least one guide member for supporting said carriage for sliding movement along said writing line; B. a position-settable left margin stop for said carriage, said stop supported by and incrementally positionable along said guide member, said stop comprising one mating member of a separable dashpot; C. carriage return motion snubbing means comprising the other mating member of said dashpot mounted on said carriage for slidable engagement with said first mating member to effect snubbing; and D. wherein said mating members of said dashpot comprise telescoping concentric tubular pistons and respective mating annular recesses to form a labyrinthine passage of increasing length during engagement of each other to increasingly restrict the exhaust of air therefrom.
2. A page printer in accordance with claim 1 wherein said printer is responsive to electrical input signals and said left margin stop is positionable to a desIred margin position by means responsive to electrical activation.
3. In an electrical input signal responsive printer of the type having a carriage incrementally positionable to effect line composition of characters along a writing line, the combination including: A. positioning means for moving said carriage; B. electrical control means for said printer including spacing and carriage return operations in response to respective input signals therefor; C. a margin position memory cooperable with said control means, said memory having a plurality of margin position-defining means which are selectively conditionable to a set state or a cleared state, such that at least one set means defines one margin position for said carriage to establish a maximum length of writing line; and D. margin position memory conditioning means to set and clear said position-defining means in response to electrical activation for either a margin set or a margin clear operation; E. said combination further including margin position memory readout means responsive to said incremental positioning for serially scanning said memory to sense and provide an electrical output signal when a set margin position-defining means is sensed as it occurs in metered relationship to the position of said carriage, said output signal serving to indicate to said control means that the carriage is at the sensed margin position, and wherein said conditioning means employs electro-magnetic means to effect setting and clearing of said margin position-defining means.
4. In an electrical input responsive printer of the type having a carriage incrementally positionable to effect line composition of characters along a writing line, the combination including: A. positioning means for moving said carriage; B. electrical control for said printer including spacing and carriage return operations in response to respective input signals therefor; C. a margin position memory cooperable with said control means, said memory having a plurality of margin position-defining means which are selectively conditionable to a set state or a cleared state, such that at least one set means defines one margin position for said carriage to establish a maximum length of writing line; and D. margin position memory conditioning means to set and clear said position-defining means in response to electrical activation for either a margin set or margin clear operation; E. said combination further including margin position memory readout means responsive to said incremental positioning for serially scanning said memory to sense and provide an electrical output signal when a set margin position-defining means is sensed as it occurs in metered relationship to the position of said carriage, said output signal serving to indicate to said control means that the carriage is at the sensed margin position; and wherein said conditioning means employs electro-magnetic means to set and clear said margin position-defining means, and wherein said readout means magnetically senses each set margin position-defining means.
5. In an electrical input signal responsive printer of the type having a carriage incrementally positionable to effect line composition of characters along a writing line, the combination including: A. positioning means for moving said carriage; B. electrical control means for said printer including spacing and carriage return operations in response to respective input signals therefor; C. a margin position memory cooperable with said control means, said memory having a plurality of margin position-defining means which are selectively conditionable to a set state or a cleared state, such that at least one set means defines one margin position for said carriage to establish a maximum length of writing line; and D. margin position memory conditioning means to set and clear said position-defining means in response to electrical activation for either a margin set or margin clear operation; E. said combination further including margin position memory readout means responsive to said incremental positioning for serially scanning said memory to sense and provide an electrical output signal when a set margin position-defining means is sensed as it occurs in metered relationship to the position of said carriage, said output signal serving to indicate to said control means that the carriage is at the sensed margin position; F. said printer further includes a mechanism supporting framework; G. said memory comprises a linear array of memory elements, said array supported by said framework parallel to said writing line and in proximity to the line of motion of said carriage; and H. said readout means is supported by said carriage for said scanning of said memory means.
6. In an electrical input signal responsive page printer of the type having a carriage incrementally positionable to effect line composition of characters along a writing line by printing means, the combination including: A. positioning means for moving said carriage; B. electrical control means for said printer including said positioning to effect carriage movements including spacing and carriage return in response to respective input signals therefor; C. margin position memory means, cooperable with said control means, having a plurality of various elements selectively conditionable to either a set or a cleared state whereby respective selected and set elements define the left and right margin positions for said carriage to secure or establish a desired length of writing line; and D. memory conditioning means to set and clear said elements in response to respective electrical activation for either a margin set or margin clear operation; E. and wherein said memory conditioning means employs electro-magnetic means to set and clear said elements.
