20080273203 | METHOD OF EVALUATING PERFORMANCE OF OPTICAL SENSOR AND INK JET PRINTING APPARATUS - Provided are a method of precisely evaluating the performance of an optical sensor including light-emitting elements corresponding to light-emitting wavelengths respectively representing multiple colors as well as a light-receiving element even under a condition in which mists of color inks adhere to the sensor, and a printing apparatus for carrying out the method. To this end, how much the performance of the optical sensor mounted on a carriage decreases is evaluated based on a cumulative number of ejections for each ink color, which number corresponds to the amount of mist, and a degree at which each ink affects each color LED. This makes it possible to precisely evaluate the performance of the optical sensor including the light-emitting elements corresponding to the light-emitting wavelengths respectively representing the multiple colors as well as the light-receiving element even under the condition in which the mists of the color inks adhere to the sensor. | 11-06-2008 |
20090219534 | IMAGING DEVICE FOR SOLDER PASTE INSPECTION - An exemplary imaging device for inspecting solder paste deposited on a printed circuit board includes a first light source, a second light source, and a camera. The first light source and the second light source are disposed adjacent to two different sides of the printed circuit board and above the printed circuit board.
