In apparatus for thermally transferring ink from a ribbon, having backing and ink donor layers, to a letter, wherein the apparatus includes a frame, a thermal printhead and a printhead backing roller, there is provided an improvement for urging a ribbon and letter into engagement with one another. The improvement includes the printhead backing roller connected to the frame for rotation in engagement with a letter fed between the roller and a ribbon, and the printhead backing roller including a body portion adapted to flex when engaging a letter for urging a letter into contact with the ink donor layer of a ribbon. Moreover, it is of the invention that the roller body portion include at least one channel formed therein.

Disclosed is a portable magnifier camera that can be selectively positioned into a variety of configurations. At least four distinct viewing configurations are provided: a reading mode wherein the camera rests flatly upon the viewed object; a writing mode wherein the camera rests at an angle upon the viewed object; a hand-held mode wherein the user holds the camera relative to a distant object; and an inspection mode wherein the user holds the viewed object relative to the camera. These configurations enable a user to effectively view objects of differing size and at varying distances.

An electromechanical Braille cell assembly includes a plurality of parallel bimorph reeds. A first plurality of bimorph reeds is mounted to a first side of a printed circuit board by a first plurality of clips and a second plurality of bimorph reeds is mounted to a second side of the printed circuit board by a second plurality of clips. A frame has a top wall, a bottom wall, a first side wall in the form of an angle wall and a second side wall in the form of a flat wall. Pinholes are formed in the angle wall to accommodate Braille pins and the flat wall is slotted to accommodate a plurality of printed circuit boards. A monolithic cap covers all of the Braille pins. Pinholes formed in the cap receive the respective tips of the Braille cells when actuated bimorph reeds cause displacement of the Braille pins.
