High speed printer

Claim 2

In a printer having a plurality of print positions along a print line, the combination comprising: a type element bearing a plurality of type characters and being supported for movement past a print line for presenting type characters borne thereon at said plurality of print positions, a print hammer for impacting a recording medium against a selected type character on said type element at a print position of said print line, said print hammer being pivotally supported for pivotal movement between a rest position and said type element, and guide means for guiding the movement of said print hammer between said rest position and said print element, said print hammer being resilient for flexing about its said pivotal support in a direction transverse to its pivotal movement, said guide means being movable substantially along the print line for flexing said print hammer from one of said plurality of print positions to another of said print positions.

Claim 3

In a printer according to claim 1: said type element bearing said plurality of type characters in at least two columns for movement past a print line and serving to define two print positions on the print lines, and said print hammer having a width corresponding to substantially a single column of type characters for impacting against a type character in only one of said two columns of type faces.

Claim 4

In a printer, the combination comprising: a print drum supported for rotational movement and having type characters arranged in columns about the periphery for movement past a print line, a print hammer supported for pivotal movement to impact against a selected type character on one of said columns of type characters on said print drum, a cam supported for rotational movement for driving said print hammer to impact against a type character, an electromagnetically actuated interposer means supported in engagement with said print hammer and operable in response to a print signal for engaging said cam to drive said print hammer to impact against a type character on said print drum, guide means for guiding the movement of said print hammer to said print drum, said print hammer being resilient about the pivotal support thereof in a direction transverse to its pivotal movement, and said guide means being movable transversely to the pivotal movement of said print hammer for flexing said print hammer to impact against a type character in another column on said print drum.

Claim 5

In a printer, the combination comprising: a print drum supported for rotational movement and having type characters arranged in columns about the periphery for movement past a print line, a print hammer supported for pivotal movement to impact against a selected type character on one of said columns of type characters on said print drum, a cam supported for rotational movement for driving said print hammer to impact against a type character, an electromagnetically actuated interposer means supported in engagement with said print hammer and operable in response to a print signal for engaging said cam to drive said print hammer to impact against a type character on said print drum, guide means for guiding the movement of said print hammer to said print drum, said print hammer being resilient about the pivotal support thereof in a direction transverse to its pivotal movement, and said guide means being movable transversely to the pivotal movement of said print hammer for flexing said print hammer to impact against a type character in another column on said print drum.

Claim 6

In a printer according to claim 3: said guide member being supported for movement substantially parallel to the print line to flex said print hammer for printing at one print position to another print position, and another electromagnetic means operable in response to a signal to shift the print position of said print hammer for moving said guide member to flex said print hammer from one print position to another print position.
