Abstract

Provided is a metering device for determining rotation position of a character wheel by using a three-segment oppositely-emitting photoelectricity. The metering device comprises an oblate cylindrical character wheel body equipped with a first light-penetrating window, a second light-penetrating window, and a third light-penetrating window which axially run through the character wheel body. The three light-penetrating windows are arranged against forward rotating direction of the character wheel body. The character wheel body also comprises a photoelectricity module and a coded data processing module. The photoelectricity module is arranged around the cylinder of the character wheel body and comprises five sets of photoelectric tubes, each set including photoelectric tubes arranged opposite to each other. The metering device effectively reduces axial thickness of the character wheel body. The photoelectricity module outputs five-bit coded information. Not only is the rotating position of the character wheel body determined, but also rotating direction of the character wheel body can be judged by the coded information. Thus the problems of incorrect counting when the character wheel rotates reversely and inaccurate carry judgement in the products with conventional technology are resolved.
