摘要： The present invention provides a multiple-wheel input device comprising a positioning plate, two light-penetrating type encode wheels, a circuit board, and two hollow rollers. The light-penetrating type encode wheel is connected pivotally to both sides of the positioning plate. A gap hole is disposed at the central part of the bottom edge of the positioning plate. Two inclined surfaces are formed at the top edge of the gap hole. An arched board is installed at each side of the gap hole. A fixing bar is installed adjoining to each side of the bottom edge of the gap hole to join the circuit board. A light-emitting device is installed at the central part of the circuit board. A light-receiving device is installed at each side of the light-emitting device. The hollow roller is connected pivotally to the circumference of one side of each encode wheel and outside the two arched boards. When the roller is turned, the encode wheel is jointly turned synchronously. The light emitted from the light-emitting device is reflected by the inclined surface, penetrates the transparent portion of the encode wheel, and is received by the corresponding light-receiving device. The light variation signals are converted to the current variation signals of the light-receiving device. The movements in the X-Y coordinates of the input device (mouse) can thus be known according to the output signals of the encode wheel.

摘要： An encode device, comprises a light source, an encode wheel and a light detector. A hollow dent is formed on the center part of the incident plane of the encode wheel. The inner circumference of the dent is provided with a ring-shaped lens such that the light impinging on the inner circumference of the dent is focused by the ring-shaped lens. The rim of the encode wheel is provided with a plurality of cylindrical lenses which are perpendicular to the ring-shaped lens such that the light leaving the encode wheel can be further focused. Therefore, the working beam projected toward the chip of the light detector has less interference.

摘要： A photo-detector based calculating means having a grating wheel with integrated lenses is provided. The photo-detector based calculating means having a grating wheel with integrated lenses includes a light source (1), a grating wheel (2), and a photo-detector (3), with the light emitted from the light source (1) impinging upon an input plane of the grating wheel (2). The photo-detector (3) has a set of photo-sensitive chips (31) to receive the working light beams emitted from the grating wheel (2). The input plane of the grating wheel (2) has a ring-shaped lens (24) to focus the light emitted from the light source (1). The output plane (23) of the grating wheel (2) has a plurality of tooth-shaped lenses (25), each projecting perpendicularly to the ring-shaped lens (24), which can focus the working beams after the working beams pass through the output plane (23), thus minimizing interference.
