Abstract: A tilt adjustment mechanism having an upper housing (11), a lower housing (13) and a shaft assembly is disclosed. The shaft assembly receives the gears (17A,17B) which are pressed on either end of shaft (19). The shaft (19) fits through locating slots in the lower housing. Each of the gears (17A,17B) are activated by internal gears (23A) located on each side of the upper housing (11). The internal (23A) gears are integrally formed with the upper housing (11). The upper housing (11) is hinged on the lower housing (13) and can rotate 20 degrees. The shaft assembly mechanism provides a torsion bar function to insure that the upper housing (11) moves evenly with respect to the lower housing (13). Even motion in the upwards and downwards directions of the housing is provided by even rotational torsional motion and opposite rotational torsional motion of the shaft assembly of the tilt adjustment mechanism. The shaft assembly mechanism decouples the frictional load in the two different rotational directions about its shaft. This permits the adjustment of the forces to optimal levels in both directions. A relatively high force is desired to move the upper housing in a downward direction. This prevents the operator's touches on a display tablet, mounted to the upper housing to cause the tilt adjustment mechanism to move in the downward direction. A relatively low force is required to move the tilt adjustment mechanism in the upwards direction.

Abstract: A print head has a column of printing elements positioned at an angle between zero and ninety degrees relative to a permitted line of motion of the print head. A first motor is operable for positioning the print head along said permitted line of motion of the print head; A second motor is operable for positioning a first print receivable medium along a line of motion relative to the print head, where the line of motion of the first print receivable medium is normal to the permitted line of motion of the print head; A sensor is operable for detecting an insertion into the printer of a second print receivable medium. A third motor is operable for positioning the second print receivable medium along said line of motion relative to the print head, where the line of motion of the second print receivable medium is normal to the permitted line of motion of the print head. A process is operable for sending first signals translated through a first buffer to the first motor for controlling said first motor, second signals translated through a second buffer to said second motor for controlling the second motor, this signals translated through a third buffer to said motor for controlling said third motor, and fourth signals translated through a fourth buffer to said print head for printing images. Upon no detection of the second print receivable medium by the sensor, and receipt of the data signals, the processor is operable to control portrait mode printing of the images on the first print receivable medium by controlling positioning of the print head along the permitted line of motion of the print head. Upon (1) detection of the second print receivable medium by said sensor, and (2) receipt of the data signals, the processor is operable to control landscape mode printing of the images of the second print receivable medium by controlling positioning of the second print receivable medium along the line of motion of the second print receivable medium.

Abstract: @ The invention is a magnetically actuated clapper-style armature wire matrix print head. A unitary molded straight line channel wire matrix wire guide (1) is molded as a single pert. The flux return member (10) is a single formed part with attached magnetic cores (17). The magnetic cores (17) have thermal contact with attached or integral heat sink means (8) that extend from the flux return member in the axial direction with the cores and which may be integrated with the support frame for the print head structure. A rebound absorbing backstop member (33) receives the armatures on the rebound but also serves as a means of maintaining pivotal contact between the end of the armatures (25) and the top edge of the flux return member so that a continuous flux path from the flux return member, through the armature and down through the cores of the electromagnets can be attained.
