Print Head Adjusting Mechanism

This article relates generally to print heads and more particularly to a mechanism which permits the adjustment of a print head to a platen or roller surface.

Mechanism 1, shown in the above figure, permits vertical and horizontal adjustments to be made as well as adjustments which are perpendicular to the platen or roller. In the figure, a slide block 2 attached to mounting bar 3 by means of locking plate 4. Plate 4 is bolted to block 2 by means of machine screws (not shown) which pass through holes 5 in plate 4 and screw into threaded holes 6 in block 2. Back plate 7, on which the print head (not shown) is mounted by means of holes 8, has a narrow portion 9 which fits into slot 10 in block 2. A bolt (not shown) connects portion 9 to block 2 via hole 11 in block 2 and hole 12 in portion 9. When mechanism 1 is assembled on mounting bar 3, screws in holes 13 can be adjusted to move the print head to the left or right or move it up or down. By adjusting screws (not shown) in holes 14 in plate 4, the print head can be adjusted so it is parallel to the platen or face plate. Finally. a screw (not shown) in hole 15 is used to rotate back plate 7 slightly so that the print head can be positioned the proper distance from the platen or roller.

Mechanism 1 permits all adjustments to the print head to be made from a face-front working position when the print head is installed.
