  • Publication number: 20060203230
    Abstract: A position change section of a processing device changes the position of a treatment object, at the time of performing a process by a process section, to correspond to a predetermined position in conformity to the treatment object. An inspection device inspects the occurrence of a defect on the treatment object having been subjected to processes by a plurality of processing devices. Then an analyzing process for specifying in which processing device the defect occurred is carried out based on (i) positional information of the treatment object, in each of the processing devices, and (ii) defect information defected by the inspection device. With this arrangement, during the process of manufacture of treatment objects, it is possible to precisely specify which processing device or processing device group caused the defect, without performing processes such as attaching, to the treatment object, information regarding processing devices which have conducted processes.

  • Patent number: 6898383
    Abstract: A control system for an image forming device includes a sensor mounted on an optical path unobstructed by elements that are subject to wear for detecting a time varying signal representing reflected light from both a photoconductive element and a transfer sheet internal to the image forming device, a memory storing reference values, and a controller to control an image forming operation based on the reference values stored in the memory and the time-varying signal received from the sensor. The controller reads the time-varying signal from the sensor and compares the time-varying signal read to the reference values to determine a condition of the image forming device.
