FIELD: coordinate copying duplication technology. SUBSTANCE: all three types of proposed electric mechanical scanner have hemispherical lens, multistructural one output light-sensitive cell placed at focus of lens, disk-shaped plate with microscopical slot made along diameter of disk-shaped plate, container and object driver. Object illumination system is present in first two variants of proposal. Disk-shaped plate surface is parallel to flat part of hemispherical lens and center of disk-shaped plate is set on hemispherical lens axis. Microscopical slot length is equal to paper's sheet width, like known analog has, and microscopical slot is placed close to paper in parallel to paper's sheet width. Object illumination system brightens all chromatic points of image line-part visible through slot, and light beams from these points row are going through lens making image at light-sensitive cell. Proposal third variant differs from first two by presence of shadow flat strip placed between disk-shaped plate and lens close to plate, strip length is two times more that slot length is, and it has width, which exceeds slot width by more than two times. Strip has transversal microscopical slot too, which scans image points whiles strip moving along disk-shaped slope. EFFECT: more simple construction of mechanical scanner. |
