ELECTROMECHANICAL DISPLAY MECHANISM

摘要

A mechanism by which a desired image is created on the face of a display, the mechanism comprising a mechanical multiplex of "drive belts" (4) and "engagement bars" (5), and a series of pairs of gear wheels ("pulleys") (2 and 3) each pair of which is encircled by a set of small concentric partially chromatic translucent plastic "pixel belts" (1). Each white pulley and its associated set of partially coloured pixel belts (1) makes up a "pixel" and the image is made up of a large number of pixels. The drive belts and engagement bars are activated in combination using an "xy" matrix controlled by firmware. An engagement bar, when "lifted", will deflect the drive belts and thereby bring them into direct contact with an entire row of pixel belts, and each pixel belt in the row may then be moved individually by the activation of each individual drive belt to bring each individual pixel belt to the position required of it by the image to be displayed.
