Adjustable support for print head assembly

A printer including

• a frame having end portions and a paper support surface extending transversely therebetween
• a print head assembly transversely movable along a printing line parallel to said surface and spaced therefrom and
• support means adjustably supporting and guiding said print head for said movement along said printing line and for adjustment in a generally horizontal direction perpendicular to said printing line toward and away from said paper support surface
• said support means including
• a pair of longitudinally extending print head assembly support members having axes parallel to said printing line
• one of said support members being cylindrical and extending through a bore in said print head assembly for sliding and pivotal movement thereon
• bearing means mounting said one support member on said frame for angular displacement about an axis fixed with respect to said frame and parallel to and displaced from the axis of said one support member and
• operating means for angularly displacing said one support member to move said print head assembly in a generally horizontal direction perpendicular to said printing line toward and away from said paper support surface.

• a print head assembly transversely movable along a printing line parallel to said surface and spaced therefrom and
• support means adjustably supporting and guiding said print head for said movement along said printing line and for adjustment in a generally vertical direction perpendicular to said printing line and generally parallel to said paper support surface
• said support means including
• a pair of longitudinally extending print head assembly support members having axes parallel to said printing line
• one of said support members being cylindrical and extending through a bore in said print head assembly for sliding and pivotal movement thereon
• bearing means mounting said other support member on said frame for limited angular displacement about an axis fixed with respect to said frame and parallel to and displaced from the axis of said other support member and
• operating means for displacing said other support member to move said print head assembly in a generally vertical direction perpendicular to said printing line and generally parallel to said paper support surface.

• a print head assembly transversely movable along a printing line parallel to said surface and spaced therefrom and
• support means adjustably supporting and guiding said print head for said movement along said printing line and for adjustment in directions perpendicular to said printing line both generally horizontally toward and away from said paper support surface and generally vertically and generally parallel to said paper support surface
• said support means including
• a pair of longitudinally extending cylindrical print head assembly support members each having a central axis parallel to said printing line
• one of said support members extending through a bore in said print head assembly for sliding and pivotal movement thereon,
• said print head assembly being mounted on the other of said support members for movement parallel to said printing line in a generally horizontal direction toward and away from said paper support surface
• bearing means mounting each of said support members of said frame for angular displacement about an axis fixed with respect to said frame and parallel to and displaced from the axis of its said support member and
• operating means for angularly displacing one of said support members to move said print head assembly in a generally horizontal direction toward and away from said paper support surface and the other of said support members in a generally vertical direction parallel to said paper support surface.
