Abstract: A cam shaft 23 is rotated 90 degrees when the plate 10 is fitted on the plate cylinder 60. Thus, as a result of the rotation, a flange part 3T of the tail edge side clamping base 3 is pushed by movement of a spring base 15 which receives a pushing force generated by springs 16. Therefore, the plate 10 is pulled in a tension applying direction. Since the tail edge side clamping base 3 does not receive the limitation of the cam shaft 23 directly, the tail edge side clamping base 3 can be moved in a direction parallel to a shaft of the plate cylinder 60. Thus, a diagonal image adjustment of the plate can be done easily.

In one embodiment of the invention, a print head is movable from a first position spaced-apart from the platen to a second position adjacent the platen, such that the platen and the print head define a clearance therebetween when the print head is in the first position. A dye donor cartridge, which has an elongate neck portion defining a longitudinal axis therealong, is insertable through the aperture and into the housing to a position adjacent the print head. The neck portion is sized to be received through the clearance for interference-free insertion of the cartridge. Moreover, the cartridge includes a dye donor take-up spool that has an elliptically-shaped transverse cross section defining a major axis and is capable of being oriented such that the major axis of the take-up spool is parallel with the longitudinal axis of the neck portion.

Abstract: A system and a method of printing an image represented by a frame of image data utilize a hand-held printer having optical sensors for tracking positions of the hand-held printer relative to the surface of a print medium during a printing process. The change in position of the hand-held printer during the printing process is monitored in real time using navigation information generated by the optical sensors. Each optical sensor contains an array of optoelectronic elements to capture images of the surface of a print medium at fixed time intervals. Preferably, the optical sensors can detect slight pattern variations on the print medium, such as paper fibers or illumination patterns formed by highly reflective surface features and shadowed areas between raised surface features. These features can then be used as references for determining the position and the relative movement of the hand-held printer.

Abstract: In a stencil sheet clamping construction for clamping a leading end portion of a stencil sheet to a stencil printing drum, a press plate is set at a half open position making an acute angle against an upper surface of a base portion when the leading end portion of the stencil sheet is mounted. This allows the leading end portion of the stencil sheet to be lifted above the upper surface of the base portion by floating up of an elastic film belt when the stencil sheet is discharged. This also prevents obstruction of the smooth advance of the leading end portion of the stencil when it is mounted due to the floating up of the elastic film belt.

Abstract: Printer defining a reduced exterior envelope and method of providing same. The printer comprises a housing having a top wall. The printer also has a front side wall with an aperture for receiving a dye-carrying cartridge therethrough. A printhead is disposed in the housing. A movable platen is disposed in the housing in a first position spaced-apart from the printhead and a movable arm attached to the platen and engageable with the cartridge as the cartridge is received through the aperture. The arm moves from a first location to a second location thereof as the arm engages the cartridge and the platen moves from the first position to a second position thereof adjacent the printhead as the arm moves from the first location to the second location. In this manner, the printer defines a reduced exterior envelope because the cartridge is loaded through the aperture in the front sidewall rather through the top wall of the printer.
